I forgot some passwords/codes/keys on my phone
• Perform a factory data reset.
• If you still cannot access your phone, apply to the authorized repair
center, but remember that it will not be regarded as a warranty case.
How to back up my device data
• Go to Settings > System > Backup (refer to “4.22 System > Backup”)
No action after touching the touch screen
• Check whether there is any damage to the screen. If yes, please back
up your data and take your device and proof of purchase to our repair
centre to get more professional technical assistance.
• If the issue occurs while using a third-party app, make sure the app is
compatible with your device and Android version. Try uninstalling the
third-party app.
• Check if the issue occurs during charging. If yes, we recommend trying
the official charger and data cable.
(Note: The voltage instability of non-standard chargers and data cables
may cause the touchscreen to become unresponsive).
• Make sure the temperature where the device is being used is neither too
hot nor too cold. The standard working temperature of the capacitive
touchscreen is -10°C~60°C. Excessively high or low temperatures will
cause the touchscreen to become unresponsive.
• If there is a screen protector on the screen, see if the touchscreen
works after removing it.
• Make sure there are no stains such as water or sweat on the touchscreen.
If there are, wipe the screen and try again.
• If it still doesn't work, reset the phone or update software.
Cannot turn on camera flash mode
• Charge your device until the battery level is at least 30%. Camera flash
cannot be used when the battery is running low.
