Hardware and exterior
1.1 Why does my phone not recognize my SIM card?
1. Your SIM card may not be inserted correctly.
(i) Both SIM card slots on the Mate S only support nano-SIM cards. Please ensure you use a nano-SIM
card with your phone.
(ii) If you are currently using another type of SIM card, you should request a nano-SIM card from your
network operator. Cut SIM cards are not recommended as they may have damaged contacts or fail to fit
properly, which could lead to intermittent issues. The rough edges of a cut SIM card may also damage
your phone.
(iii) If you are using a nano-SIM card, please ensure it is inserted correctly, as shown below.
2. If your phone does not recognize your SIM card, or if recognition is intermittent, try following the
steps below:
(i) Verify that you are using a standard nano-SIM card. Standard nano-SIM cards have a ring of plastic
insulation around the metal chip. If one side of this ring is missing, your card has previously been cut.
September 2015
INTERNAL
10
(ii) If you are using a SIM card that has been cut to size, it is strongly recommended that you request a
standard nano-SIM card from your network operator. Cut SIM cards are not recommended as they may
have damaged contacts or fail to fit properly, which could lead to intermittent issues.
(iii) If you are using a SIM card that has been cut in store, it is recommended that you request a standard
nano-SIM card from your network operator. Cut SIM cards are known to cause issues.
(iv) If you are using an old SIM card, you can try wiping the metal contacts with alcohol to remove
oxidation. If problems persist, you should request a new nano-SIM card from your network operator.
(v) If you are using a China Telecom SIM card, this is only compatible with the custom China Telecom
Mate S model (CRR-CL00/CL10). China Telecom SIM cards will not work with China Mobile or dual
4G SIM models.
(vi) If none of the above apply, please take your phone and SIM card to a service center.
Why must I use a standard nano-SIM card?
The Mate S phone is designed to accept standard nano-SIM cards only. This is to prevent damage from
the insertion of badly-cut SIM cards.
1.2 Manufacturing issues
1.2.1 Why is there a gap between the screen and bezel? Why is the gap
uneven?
1. Due to material and manufacturing limitations, it is impossible to eliminate such gaps or make them
perfectly even.
2. The gap between the screen and bezel conforms to industry quality standards (a gap no larger than 0.3
mm). Huawei phone housings exceed industry standards.
3. Try to insert two sheets of A4 paper (each 0.1 mm thick) into the gap to determine how wide it is.
If you are unable to insert both sheets, the gap is less than 0.2 mm wide, which meets standards. If both
sheets can be inserted into the gap, please take your phone to a Huawei service center.
1.2.2 Why does the camera flash catch on my hand?
The camera flash is slightly recessed to prevent it from catching and causing injury. Please note that this
does not affect performance.
Note: If the user asks for a replacement, please inform them that this issue is not covered by the
warranty.

1.2.3 Why does the fingerprint reader catch on my hand?
The fingerprint reader is slightly recessed and has rounded corners to prevent it from catching and
causing injury. Please note that this does not affect performance.
Note: If the user asks for a replacement, please inform them that this issue is not covered by the
warranty except when the product is new, out of the original packaging.
1.2.4 Why are the plastic antenna cutouts not flush with the rear cover?
The Mate S is made using the same processes as the iPhone 6. During manufacturing, nonuniform
polishing of metal and plastic parts can produce a slightly uneven finish. Please note that this does not
affect performance.
Note: If the user asks for a replacement, please inform them that this issue is not covered by the
warranty.
1.2.5 Why are there three faint marks either side of the earpiece on the
Gold Mate S?
In order to combine functionality and looks, the front indicator light, camera flash and ambient light
sensor are covered with a translucent coating. Please note that this does not affect performance.
Note: If the user requests a replacement phone, please inform them that this issue is not covered by the
warranty.
1.2.6 Why do the power key and volume key protrude by different
lengths from the phone?
The power and volume keys are moving parts and are subject to manufacturing limitations. This means
they are not entirely uniform. This issue is not considered a fault unless performance is affected.
September 2015
INTERNAL

Note: If the user asks for a replacement, please inform them that this issue is not covered by the
warranty if it does not affect performance.
1.2.7 The paint has rubbed off my black/purple phone, leaving white
marks visible. Why?
1. All phones are checked thoroughly for cosmetic defects before they are shipped.
2. Paint near micro-USB connectors, headset sockets, SIM card trays and pin holes is susceptible to
scraping. Paint on the phone's rear housing can be rubbed off when the phone is placed on a table or in
pockets.
3. The above issues are common to all dark-colored metal phone housings and are not considered faults
unless they affect the functioning of the phone.
Note: If the user asks for a replacement, please inform them that this issue is not covered by the
warranty.
1.2.8 The rear cover on the phone bends when pressed. Why?
The thickness of phone batteries varies with charge. By design, there is a safety gap between the battery
and rear cover. If the rear cover is pressed, there will be some movement, but this is entirely normal.
Please rest assured that all Huawei phones must pass strict quality checks before they are shipped.
Note: If the user asks for a replacement, please inform them that this issue is not covered by the
warranty.
1.2.9 The tempered glass screen protector has an uneven surface. Why?
Screens are rigorously checked for defects before shipping. The phone features a Corning Gorilla Glass
3 screen which is highly scratch-resistant and can withstand ordinary scrapes and knocks. Additional
screen protectors are not required.
If users insist on using a tempered glass screen protector, it is recommended that they purchase the
official Huawei super-thin (0.2 mm thick) tempered glass screen protector on Vmall.
If the issue persists, users should take their phone to a Huawei service center where the official Huawei
protector can be applied by a technician.
Note: If the user asks for a replacement, please inform them that this issue is not covered by the
warranty if it does not affect performance.
(Below is the method used by service center technicians to apply screen protectors. Telephone and
online support staff should ignore this section.)
Service center application method:
If the surface of the 0.2 mm super-thin tempered glass screen protector is uneven, technicians should
assist users as follows:
Loosen the two screws located at the bottom of both sides of the phone.
Squeeze out any air bubbles beneath the tempered glass screen protector.
Replace the two old screws with new ones and tighten.
Note: Service centers should keep T2 screwdriver bits for the aforementioned screws. T3 bits should
also be kept in case screws are damaged during removal, in which case T3 bits should be used.

1.2.10 After some use, the phone's front and rear housing have dents.
Why?
1. Huawei phones comply with industry quality standards and are checked rigorously before they are
shipped.
2. The rear housing is made of aluminum alloy, which can be dented by hard impacts. It is
recommended that you use a protective phone case.
Note: If the user asks for a replacement, please inform them that this issue is not covered by the
warranty.
1.2.11 The rear camera lens cover is cracked or scratched. Why?
1. All lenses are rigorously checked for defects before shipping. Lens covers are made with sapphire
glass which is scratch-resistant and can cope with ordinary scrapes and knocks. However, lens covers
may crack or become scratched if struck by sharp, hard objects.
2. Users should use a protective case and keep their phone away from sharp or abrasive objects such as
keys or grit.
3. In principle, the user is responsible for any post-sales damage caused to the rear lens cover. Such
damage cannot be repaired under the warranty, but the camera lens can be replaced outside the warranty.
Note: If the user asks for a replacement, please inform them that this issue is not covered by the
warranty.
1.2.12 Why is the rear flash cover recessed?
The camera flash is slightly recessed to prevent it from catching and causing injury.
Note: If the user asks for a replacement, please inform them that this issue is not covered by the
warranty.
1.2.13 Why is there a gap between the rear housing and the phone keys
or SIM card tray? Why is the gap so wide or uneven?
1. The SIM card tray and keys are moving parts and are subject to material and manufacturing
limitations. It is impossible to eliminate such gaps or make them perfectly even.
2. The gap conforms with industry quality standards (a gap no larger than 0.3 mm). Huawei phone
housings exceed industry standards.
3. Try to insert two sheets of A4 paper (each 0.1 mm thick) into the gap to determine how wide it is.
If you are unable to insert both sheets, the gap is less than 0.2 mm wide, which meets standards. If both
sheets can be inserted into the gap, please take your phone to a Huawei service center.

2.3 What is multi-window mode and how do I enable it?
Multi-window mode is also known as multi-screen mode. It allows you to run multiple apps
concurrently on your phone. Currently, Huawei phones are able to display two screens at a time. Not all
apps support this feature. Select Add to see a list of compatible apps.
How to enable multi-screen mode:
First enable Multi-screen from the drop-down shortcuts screen. Return to the home screen then touch
and hold Recent to enter multi-screen mode.
Note: You can touch the Back key, Home key or Recent key to exit multi-screen mode.
2.4 What is encrypted SMS?
Encrypted SMS is a highly secure, encrypted messaging service. When encrypted SMS is used,
messages are encrypted on the sender's phone before being sent. Recipients must decrypt messages
using their Huawei ID password before they can be read. This makes SMS messages much more secure.
Messages are stored on servers in an encrypted form or are kept in the phone's secure storage module.
In order to use encrypted SMS, both the sender and the recipient must use supported Huawei phones
with the encrypted SMS feature enabled. To enable encrypted SMS, you must associate your phone
number with a Huawei ID. A number can only be associated with one ID. An ID can be associated with
more than one number. When you change your phone or SIM card, this account association will not be
affected provided you retain your old number.
2.4.1 How do I activate encrypted SMS?
First ensure you have a working data or Wi-Fi connection. Open the Menu beneath the message list and
select Settings and then Attach signature to open the encrypted SMS menu. Enable the switch for the
SIM card you wish to use and then follow the instructions to activate the encrypted SMS feature.
September 2015
INTERNAL
19
2.4.2 Encrypted SMS activation failed. Why?
1. Your phone needs to send SMS messages to activate this feature. Please check that you have
sufficient calling credit.
2. Please ensure you have good phone reception when trying to activate the encrypted SMS feature.
2.4.3 When I send an encrypted message, the recipient only sees garbled
text. Why?
If the recipient's phone does not support the Huawei encrypted SMS feature, please use ordinary SMS.
2.4.4 I am unable to view encrypted messages. Why?
Ensure that the SIM card used to receive messages is inserted and then try again.
2.4.5 Nothing happens when I select an encrypted SMS. Why?
Users of phones produced by other manufacturers may be accustomed to opening encrypted messages
with a single touch. On Huawei phones, users should open encrypted messages with a quick double
touch.
To open an encrypted message, users must touch the text inside the message dialog box, as shown below.
If users only touch the edge of the box, the encrypted message will not be opened. If users report that
they are unable to open encrypted messages, please check that they have touched the text inside the box.
September 2015
INTERNAL
20
2.4.6 The remaining characters counter to the right of the compose
window is inaccurate. Why?
The number of characters you type may not match the decrease shown by the remaining characters
counter. This is because the total character count for a message may change after it is encrypted. The
counter on the right shows the number of characters remaining after the message has been encrypted.
2.4.7 Why are some messages still garbled even after I decrypt them
with my password?
A password for one Huawei ID cannot be used to decrypt messages retrieved with a different Huawei ID.
If you have used different Huawei IDs to retrieve encrypted messages during one session, you will not
be able to use one Huawei ID password to decrypt all of them. For example: After retrieving an
encrypted message using phone number XXX, you may change the SIM card (and associated Huawei
ID) and retrieve another encrypted message using phone number YYY. When you open the message list
and select an encrypted message, you will be prompted to enter your Huawei ID password. This
password will only decrypt messages that were downloaded with the corresponding Huawei ID.
2.4.8 Why can't I copy or forward encrypted messages?
Encrypted messages are sent, received and stored in an encrypted form. Recipients must decrypt
messages using their Huawei ID password before they can be read. This makes SMS messages much
more secure. Even if an encrypted message is copied or forwarded to another recipient, they will be
unable to decrypt its contents. Therefore, in the interest of security, encrypted messages can only be
viewed by you and cannot be copied or forwarded.
2.4.9 Why can't I always use my fingerprint to decrypt messages?
To use fingerprint decryption, the following conditions must be met:
1. The Huawei ID used to receive the message must match the ID of the current SIM card.
2. The Huawei ID associated with the encrypted SMS feature must also have an associated fingerprint.
2.4.10 How do I back up and restore encrypted messages?
For security reasons, when the user syncs encrypted messages to the cloud, they will be stored in an
encrypted format on the remote server. Only the user who backed up the encrypted messages may
download and decrypt them. To use the backup and restore feature, you must use a Huawei phone that
supports encrypted SMS. The same Huawei ID must be used both to back up and restore. The user can
use the backup feature to back up encrypted messages to their Huawei Cloud Drive. For security
reasons, these will be stored on the remote server in encrypted form. Backed up messages can only be
restored with the Huawei ID that was used to perform the backup. Users must log in using this ID on a
Huawei phone that supports encrypted SMS and recover their messages. These can then be decrypted
and viewed.
2.5 What is native 24-bit decoding?
24-bit audio offers higher resolution audio playback. All audio output on the Mate S's HiSilicon Kirin
935 chip is 24-bit.
September 2015
INTERNAL
21
Native decoding allows audio files to be decoded and played by your phone's digital signal processor
(DSP), which currently supports MP3 and WAV files. This setup is called low-power audio playback
and allows your phone to consume very little power while playing music.
Low-power audio playback limitations:
MP3: Low-power playback is supported for non-VBR, stereo MP3 files (videos not included) played
through the earpiece, loudspeaker or a wired headset. MP3 files must be stored locally and have a
duration of more than one minute (internet streams are not supported). Playback is not supported if
other music players are using low-power playback mode or if there is an active phone call, internet call
or VOIP call. The music player must be configured to play only audio files.
WAV: Low-power playback is supported for stereo WAV files (videos not included) played through the
earpiece, loudspeaker or a wired headset. WAV files must be stored locally and have a duration of more
than one minute (internet streams are not supported). Playback is not supported if other music players
are using low-power playback mode or if there is an active phone call, internet call or VOIP call. The
music player must be configured to play only audio files.
2.5.1 If I need to achieve a signal-to-noise ratio (SNR) of 110 dB, what
sort of test file should I use?
You should perform the test with a 24-bit WAV file.
2.5.2 When listening to music, how do I activate low-power audio
playback to prolong battery life?
Please refer to the above limitations for guidance on using low-power audio playback.
2.6 How can I print from my phone?
Check that your printer supports the Mopria Print Service. You will not be able to the use the print
feature if your printer does not support the Mopria Print Service, therefore be sure to check with your
printer retailer before purchasing to ensure that you choose the correct model.
Once you have confirmed that your printer supports the Mopria Print Service, you need to establish the
connection with your printer. The connection is made using the default Mopria printing protocol. We
recommend using the connection method outlined in (i) below for faster printing speeds and a better
user experience.

2.11 Why doesn't the screen turn off when I place my phone
next to my ear during a call?
Ensure that your ear covers the proximity sensor. The screen will only turn off when the proximity
sensor is covered. Keeping the earpiece level with your ear should resolve this issue. If the earpiece is
not next to or level with your ear during a call and you do not touch the display, the screen will turn off
automatically after a short period. Press the power key to turn the display back on.

2.14 Smart screenshot
2.14.1 What is smart screenshot?
Smart screenshot is brand-new touch technology jointly developed by Huawei and Qeexo. This
technology can distinguish touch operations by fingers or knuckles. Your phone includes this technology.
You can double-touch any screen using your knuckles to achieve instant screenshot, which improves
screenshot efficiency.
You can also draw a circle on the screen using your knuckle to partially capture the screen. For example,
to share a part of a WeChat record, circle the content using your knuckle to share it with others.
2.14.2 Are there any differences between screenshot using knuckles or
composite buttons?
No.
2.14.3 Why does my phone suddenly take a screenshot when I use it
normally?
Your phone takes a screenshot based on the instructions from your knuckles by detecting the screen
touch capacity and gravity sensor signals. The probability of triggering the screenshot with fingers by
mistake during normal use is extremely low. You may occasionally trigger screenshot if you
continuously knock the screen hard with your nails. Make sure you use the phone normally, and do not
knock the screen hard with your nails.
2.14.4 How do I partially capture the screen?
On any screen, use the knuckle of any finger (such as the thumb or index finger) to touch the screen a
little harder, and then draw a closed pattern without leaving the screen. After your phone successfully
identifies the knuckle, it generates a blue track that moves along your knuckle's path.

INTERNAL
27
*For reference purposes only. Your phone's interface may differ from the interface shown in this image.
2.14.5 Why can't I draw a track and partially capture a screenshot using
my knuckle?
Your phone implements partial screenshot based on the gravity sensor signals. If you only lightly draw a
circle on the screen, even when you use your knuckle, your phone can't receive the signals. Rapidly
draw a circle on the screen a little harder to achieve partial screenshot. Practice several times to master
this operation.
2.14.6 How do I disable the Smart screenshots feature?
Go to Settings > Motion control > Smart screenshots/Screen recording and turn off the switch.
2.14.7 Why do I fail to partially capture the screen even if I draw a
circle?
Successful screenshot using your knuckles depends on whether the circle is closed and whether any
lines are crossed. If you draw a rectangle or a circle, screenshot is successful in most cases. However, if
the shapes vary greatly from the algorithms, for example, 6, C, 8, and W, screenshot fails. Screenshot
can be successful if an irregular polygon is closed, for example, a heptagon or a starfish. Practice more
to master this operation.
2.14.8 Does smart screenshot affect the phone's standby time?
The algorithm for identifying the knuckles is integrated on the hardware drive and consumes very little
current. Therefore, it doesn't affect the standby time.

2.15.2 When I am using the Mini mode for screen recording, why does
the recording consist of several files, each of around 10 MB?
The Mini mode is designed to make it easier for users to share screen recordings quickly using instant
messaging apps such as WeChat. Instant messaging apps place restrictions on the size of video files that
can be sent to friends, e.g. WeChat, which does not allow files larger than 20 MB. Any videos larger
than the app's limit will be compressed by the app, which significantly decreases the video resolution.
Mini mode provides a solution to this issue by creating a new video file each time a recording file
reaches a certain size (e.g. 19 to 20 MB).
Due to the file size restrictions of many popular instant messaging apps, the size of each video file in
Mini mode is 15 to 16 MB for models purchased outside of China.
2.15.3 Why is the resolution poor when using Mini mode for screen
recording?
As described in section 2.15.2 "When I am using the Mini mode for screen recording, why does the
recording consist of several files, each of around 10 MB?", the Mini mode is designed to record videos
that can be sent using instant messaging apps. The size of each video file is restricted to prevent instant
messaging apps from compressing the video. If the resolution is set to high, a 19 to 20 MB file will only
record a very short clip.
If the resolution is set to high and there are no file size restrictions, the resolution will decrease
significantly when the video is sent using an instant messaging app, as the app will compress the video
to a lower resolution.
We therefore opted for FWVGA resolution for clips recorded in Mini mode in order to keep the file size
low and ensure an acceptable image quality.
You can also record a screen recording using HD mode and then share your clip by uploading it onto a
video-sharing website.
2.15.4 Why can't I record a video, make a voice recording, or send voice
messages when I am using the screen recording feature?
Your voice is recorded automatically when you make a screen recording. Starting a screen recording
will turn on your phone's microphone. Android does not currently support the use of the microphone by
more than one app at once. This means that you cannot record video, make a voice recording, send
voice messages, or use other apps that require the use of the microphone when you are using the screen
recording feature. Turn off screen recording if you wish to access these features.
2.15.5 Where are screen recording files stored? Why does my phone say
that there is insufficient storage space when I still have space
remaining on my microSD card (or internal storage)?
Screen recording files are saved in the system's default storage location. You can change the default
storage location by going to Settings > Device > Storage > Default storage.
2.15.6 Why does the screen recording end automatically?
The screen recording will end automatically in the following circumstances:

September 2015
After 5 minutes of recording
INTERNAL
32
Just like video recording, the screen recording feature involves processes such as audio and video
encoding, which increase battery consumption. In addition, screen recording files also take up space on
your phone's internal memory. A 5-minute screen recording is normally sufficient for most users. In
order to avoid excessive battery consumption/large file sizes, the maximum screen recording time is
restricted to 5 minutes.

When you make/receive calls
The screen recording feature will record your voice. In order to prevent any confidential information
that you discuss during a call from being inadvertently disclosed when you share your screen recording
online, your phone will automatically stop and then save your screen recording when you make/receive
a call.

When there is insufficient storage space
When you have insufficient storage space (less than 50 MB), many of your phone's features may be
restricted by the system and your phone may slow down significantly. The screen recording will stop
automatically in order to prevent your phone from slowing down further and ensure that basic features
(e.g. calling) continue to function properly.

When the screen goes off due to inactivity or pressing the power key.
Screen recordings will end automatically when the screen goes off to reduce power consumption.

When your phone switches to Ultra power saving mode
Ultra power saving mode is designed to be used when the battery level is low. In ultra power saving
mode, you can only use your phone's basic features such as calling/messaging. All other features will be
disabled. When this mode is enabled, your screen recording will be stopped and saved automatically.
2.15.7 I always need to wait for the timer to countdown before the
screen recording starts. Is there a quicker way to start a screen
recording?
Touch the timer to skip the countdown and start recording immediately.
2.15.8 The screen recording timer button is obstructing the controls in
my game. What can I do?
You can drag the timer button to another location on the screen.
2.15.9 My screen recording failed to be shared over WeChat?
Check that you followed the correct steps to share your video. We recommend that you touch the Share
button, which you can find in the Gallery or by swiping down on the notification bar. Select WeChat to
share your screen recording with your friends.
If you use the "+" icon in WeChat to select your screen recording, WeChat will compress your video. If
compression fails, your recording will not be sent. Even if your recording is sent, the resolution will
decrease significantly due to compression. We therefore recommend that you do not use this method to
send your videos in WeChat.

starting/stopping a screen recording. Why?
Check that motion control is enabled for screen recording by going to Settings > Motion control >
Smart screenshots/screen recording.
Your phone's gravity sensor must register your knuckle gesture in order for the motion control feature to
work properly. If you only touch very lightly on the screen, the gravity sensor will not register your
gesture. Try touching slightly harder on the screen (similar to how you would knock on a door). Practice
touching twice on the screen with two knuckles to start/stop screen recordings.
2.15.11 Why can't I play screen recordings in full-screen mode on my
phone (or my friend's phone)?
Make sure that you are using your phone's default video player. Some online video players are unable to
detect the video orientation automatically, therefore you will not be able to play the video in full-screen
mode.
2.15.12 Why doesn't the virtual navigation bar work when I'm playing a
screen recording?
Check whether the virtual navigation bar is part of the screen recording. Your phone's video player will
automatically hide the virtual navigation bar during playback so that you can view your screen
recording in full-screen mode. This means that the virtual navigation bar you see on the screen is
actually part of the screen recording.
If you want to access the phone's navigation bar during playback, simply touch the center of the screen.
2.15.13 When sending screen recordings in WeChat, why does WeChat
need to compress the recording? Why does the resolution decrease?
WeChat restricts the size of video files that are shared with friends to a maximum of 20 MB.
When you record in HD mode, even a short recording is likely to exceed 20 MB, therefore WeChat will
compress the file before it is sent.
If you wish to share your screen recording using WeChat, we recommend that you select Mini mode to
make your recording. This mode will use a lower bit rate (compared with HD mode, the quality will
decrease slightly). In addition, the recording will be split into numerous files of no more than 19 to 20
MB each, enabling you to send each file in WeChat without the need to compress your recording.

2.16.3 Why does the size of image previews vary? When I release my
finger, why doesn't the phone open the image?
When you touch an image, the size of the image preview will vary between the size of month view
thumbnails and week view thumbnails, depending on how much pressure you apply to the screen. When
the size of the preview reaches its maximum (i.e. the size of a thumbnail in the week view), release your
finger to open the image. If you release your finger before the preview reaches the maximum size, the
image will not open.
2.16.4 How can I disable the preview feature in the month view?
Go to Settings > Accessibility > Pressure sensing and then disable Image zoom.
2.16.5 Is the image preview feature in the month view still available

3.16 Why can I still turn the Unlock screen switch on/off when
there are no fingerprints in the fingerprint list?
Check whether you have enabled Privacy protection and added a visitor fingerprint. If the owner has not
added any fingerprints, a visitor fingerprint can still be added to unlock the screen and enter visitor
mode, therefore the screen lock switch can still be turned on/off.
To view the list of visitor fingerprints, go to Settings > Privacy & passwords > Security > Privacy
protection, then enter the screen unlock password and touch Manage fingerprints.
3.17 My phone vibrates when fingerprint unlock fails. Can I

2. If you have enrolled your fingerprint, go to Settings > Fingerprint ID > Fingerprint management
and check whether Unlock screen has been enabled.
3. Make sure you use the correct finger to unlock your phone. For example, if you have enrolled the
fingerprint of your index finger but use the middle finger to unlock your phone, your phone can't be
unlocked.
3.24 Why does the fingerprint unlock feature frequently fail to
work properly?
The fingerprint sensor on Huawei phones is designed to work at temperatures ranging from –20℃ to
+75℃. If the fingerprint sensor fails to recognize your fingerprint, this is usually due to the ambient
conditions.
This problem is normally observed during cold periods when the finger's skin is susceptible to peeling,
causing temporary changes in the shape of your fingerprint. In addition, the fingerprint sensor may also
not work properly late at night or when you wake up in the morning due to changes in the depth of
fingerprint ridges caused by dry fingers and slow circulation.
1. Check whether the skin on your finger is dry, peeling or damaged.
The fingerprint sensor is designed to work at temperatures ranging from –20℃ to +75℃.
Solutions:
Use another finger.
Use skincare products to keep your skin moist and prevent it from peeling or cracking.
If you are suffering from dry skin, exercising or using warm water to wash your hands can help relieve
the problem.
2. Check whether the surface of the fingerprint sensor is dirty. Clean it if necessary.
3. If the fingerprint sensor is still not working properly, check whether your phone vibrates when you
use the sensor. If so, this means your phone did not recognize your fingerprint and the screen was not
unlocked.
Solutions:
Try to cover the whole of the fingerprint sensor with your fingertip.
You can record six images for each fingerprint - two for the center of each fingerprint (the most
commonly used part) and four for the surrounding areas. The greater the surface area you record, the
greater the accuracy of the fingerprint sensor. Try registering your fingerprint again following the steps
above. When registering your fingerprint, avoid using the same area of your finger for each of the six
images.
September 2015
INTERNAL
51
3.25 Why does it takes a long time to unlock the screen after my
phone has been used for a certain period?
1. Your fingers may become dry in autumn and winter. In this case, you can press your finger against the
fingerprint sensor more strongly and keep your finger moderately humid by blowing hot air on it or
washing it.
2. Blood circulation slows when you sleep and the fingerprint pattern gets shallower. Even though the
fingerprint characteristics remain unchanged, it may feel smoother. In this case, you need to press
harder.
3. The working temperature of the fingerprint sensor is from –20°C to +75°C.
3.26 Why does my phone fail to read my fingerprint?
1. Your phone may fail to read your fingerprint if your finger is too dry, sweaty, wet, or is damaged.
Wipe your finger and try again. If your fingers are dry, you may need to press your finger against the
sensor more strongly.
2. You can try enrolling your fingerprint again. While you are enrolling your fingerprint, use the gesture
you often use, enroll as many fingerprint areas as possible, and avoid enrolling the same area of your
fingerprint, so the enrolled fingerprint image will be consistent with that read by your phone when you
press your finger against the fingerprint sensor.
3. Make sure the finger area you press against the fingerprint sensor is the same as the one you enrolled
on your phone. It is recommended you use the gesture you often use when you enroll your fingerprint.
3.27 What can I do to successfully unlock the screen if my
fingers are dry?
When your fingers are dry naturally, in dry seasons (autumn and winter) or in plateau areas, during rest,
or after you carry heavy objects, you may fail to unlock the screen using your fingerprint.
Fingerprints increase the friction between your finger and the object you want to touch. If your
fingerprint is too dry, the friction will decrease.
Solution:
1. Press your finger against the fingerprint sensor more strongly.
2. Keep your fingers moderately humid by blowing hot air onto them or washing them.
3.28 What can I do to successfully unlock the screen if my
fingers are wet or sweaty?
If your fingers are sweaty or still wet after you wash your hands, you may fail to unlock the screen
using your fingerprint.
To solve this problem: Wipe your fingers with tissues and ensure your fingers are free of water or sweat.
September 2015
INTERNAL
52
3.29 Why do people whose fingerprint patterns are shallow
often fail to unlock the screen using the fingerprint?
Female and children's fingers are slim and their fingerprint patterns are shallow.
1. Slim fingers may not be able to touch the edges of the fingerprint sensor, which may result in an
incorrect fingerprint image collection. The edges of your phone's fingerprint sensor provide a weak but
stable electricity signal. When a finger touches the edges, the sensor generates sensing capacitance on
its surface to produce the fingerprint image. If the finger doesn't touch the edges properly, the image
quality may be poor.
2. Shallow fingerprint patterns may also cause poor quality fingerprint images.
To solve this problem: Use the finger pad to cover the whole fingerprint sensor and its edges to enroll
clear and stable fingerprints.
3.30 Why does the fingerprint sensor often fail to recognize my
fingerprint and respond slowly when I'm unlocking the screen?
Circulation in your fingers will deteriorate in high-altitude locations, when sedentary or when lifting
heavy objects, resulting in dry skin and therefore slight changes to the shape of your fingerprint. Refer
to the solutions for dry skin above, e.g. press slightly harder on the fingerprint sensor and keep your
skin moist by breathing onto your fingers or washing your hands and then wiping them dry.
3.31 Why does my phone read my fingerprint slowly in winter
or when the weather is dry?
Your fingerprint changes with different environmental elements, such as temperature, humidity, acidity,
and oiliness. Fingerprint enrolling and reading are also affected by fingerprint patterns.
Before enrolling your fingerprint, clean your fingers. Keep your fingers in a moderate humidity and
moist condition. For example, if your fingers are too dry, your phone may fail to identify your
fingerprint.
If your fingers are sweaty, it is recommended you use tissues to wipe them before you unlock the
screen.
If your fingers are dry, you may need to press your finger against the sensor more strongly.
3.32 Why can I unlock the screen using other fingerprints?
1. Other fingers may have accidentally touched the fingerprint sensor when you were registering.
You can register six fingerprint images in total. However, it is recommended you do not register
multiple fingerprints for the same mode.
2. You may have registered the fingerprints in visitor mode.
If privacy protection is enabled, go to Settings > Security > Privacy protection > Fingerprint
Management to check.
September 2015
INTERNAL
53
3. If the problem persists, delete all the fingerprints in owner and visitor modes, restart your phone, and
register your fingerprints again.
3.33 Why can I only unlock my phone with my fingerprint after
I restart it?
Check how often this occurs. This problem is caused by a software defect rather than the hardware of
the fingerprint sensor or your phone. Please pay attention to the follow-up version instructions.
3.34 Why can't I unlock the screen using my fingerprint? Why
can't I find the fingerprint option under Settings?
If you can't unlock your screen using your fingerprint, go to Settings > Privacy & security and check
whether there is a fingerprint ID option. If not, restart your phone and check whether the fingerprint ID
option exists.
If you can't find the fingerprint ID option under Settings, take your phone to a Huawei service center.
3.35 Why can't I unlock the screen using my fingerprint when
my phone is connected to another brand charger?
Please use the standard charger that comes with your phone.
Non-standard chargers have different anti-interference capabilities. The interference from the power
supply will affect the performance of the fingerprint sensor.
3.36 Why can I unlock my screen even if my finger is not
perfectly aligned with the fingerprint sensor?
Your phone's fingerprint sensor has an identification angle of 360 degrees, so it can read your
fingerprint even if your finger is not perfectly aligned with the sensor.
3.37 Can anyone access my fingerprint information?
Your fingerprint information is stored independently within the hardware package. No one can read the
fingerprint information, and the fingerprint information will not be uploaded to any server. This storage
mechanism contributed to our cooperation with Alipay in establishing industrial standards for a
fingerprint-based payment system.
September 2015
INTERNAL
54
3.38 Why do I have to register my fingerprint several times and
at different angles?
Your phone can record a large area of your fingerprint when you register it several times at different
angles, making it easier for your phone to read. For example: If you register four different areas of your
fingerprint, you can use any one of them to unlock your phone.
When you register your fingerprint, the screen will tell you to record the center and edges of your finger
several times. Your phone has a fingerprint identification angle of 360 degrees. Press your finger against
the sensor at any angle to register it.
Multiple fingerprint images will be registered. If any image does not register, your phone will ask you to
do it again.
2. The fingerprint sensor is pressure-sensitive. There is a weak signal surrounding the depressed
fingerprint identification area. When you press your finger against this area, your fingerprint is
transmitted to the contact surface for identification.
For female users, use the finger pad to press the fingerprint sensor and make sure the edges of your
finger are fully enrolled to make it easier to unlock.
3. Fingers may be dry or wet (oily or sweaty). If your finger is dry, to avoid unclear fingerprint images,
you need to press your finger against the fingerprint sensor more strongly. If your finger is wet, sweaty,

Camera and multimedia
5.1 Optical image stabilization (OIS) doesn't work well for
large amounts of camera shake. Why?
The OIS feature can correct small amounts of camera shake in everyday shooting scenarios. However,
due to the device's limited size, it cannot stabilize an image taken with a large amount of camera shake.
5.2 The rear camera is off-center. Why?
The Mate S lens is equipped with the latest optical image stabilization technology. When you take a
photo, the phone will automatically adjust the position of the lens to capture the best possible shot.
