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 Settings > System > System
updates.
• Reset your phone via Settings > System > Reset > Factory data
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. Select Wipe data / factory reset > Yes > Factory data reset
to reset. 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, then select
Wipe data / factory reset > Yes > Factory data reset to reset.
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.
