Troubleshooting ..................
Before contacting the service center, here are some
instructions to help you troubleshoot your device:
• For optimal operation, fully charge the battery.
• To improve the phone’s performance, remove
unnecessary files or apps on your phone.
• Update your phone's software via the Updates
application. Or you can touch Settings > System >
About phone > Updates. to update software.
• Reset your phone via Erase all data (factory reset).
Touch Settings > System > Reset options > Erase all
data (factory reset). Another method is to hold down
the Power key and the Volume up key at the same
time when your phone is powered off. All your phone
data will be lost permanently. It is strongly advised to
fully back up your phone data before resetting.
and carry out the following checks:
My phone can't be switched on or is frozen
• When the phone can't be switched on, charge for
at least 20 minutes to ensure the minimum battery
power needed. Then switch it on again.
• When the phone falls into a loop during power on
animation and the user interface can't be accessed,
press and hold the Power key to reset. This eliminates
any abnormal OS booting issues caused by third
party applications.
• If neither method is effective, reset the phone by
pressing the Power key and the Volume up key at the
same time, selecting a language, and then selecting
Wipe data/Factory reset. Press the Volume key to
select, and press the Power key to confirm each
selection.
My phone has not responded for several minutes
• If your phone doesn’t respond, turn off your phone
by pressing and holding the Power key until it turns
off and then restart it again.
• If your phone has a removable battery, remove the
battery and reinsert it, then restart the phone.
• If it still doesn't work, reset the phone.
My phone turns off by itself
• Check that your screen is locked when you are not
using your phone, and make sure that the Power
key is not accidentally pressed while the screen is
unlocked.
• Check the battery charge level.
• If it still doesn't work, reset the phone or update
software.
