Troubleshooting ..............

Before contacting the service center, you are advised to follow

the instructions below:

• You are advised to fully charge ( ) the battery for optimal

operation.

• Avoid storing large amounts of data in your phone as this may

affect its performance.

• Use the FOTA (Firmware Over The Air) Upgrade tool to update

your phone's software. To access System updates, touch the

Application tab from the Home screen, then select System

updates or touch Settings\About phone\System updates.

Touch and the phone will search for the latest software.

If you want to update the system, touch the button, and

when that’s finished, touch to complete the upgrade. Now

your phone will have the latest version of the software. You

should turn on data connection or Wi-Fi before searching for

updates. Settings for auto-check frequency are also available

once you restart the phone. If you have chosen auto-check,

when the system discovers the new version, a dialog will pop

up to choose download or ignore, the notification will also

appear in status bar.

During FOTA downloading or updating, to avoid errors in

locating the correct update packages, do not change your

default storage location.

• Use Factory data reset and Mobile Upgrade tool to perform

phone formatting or software upgrading (to reset factory data,

hold down the Power key and the Volume up key at the same

time under power off mode). ALL User phone data: contacts,

photos, messages and files, downloaded applications will be

lost permanently. It is strongly advised to fully back up the

phone data and profile via Smart Suite before doing formatting

and upgrading.

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

try to switch on again.

• When the phone falls into a loop during power on-off animation

and the user interface can't be accessed, press and hold the

Volume down key to enter Safe Mode. This eliminates any

abnormal OS booting issues caused by 3rd party APKs.

• If neither method is effective, please reset the phone using the

Power key and the Volume up key (holding both together) or

upgrade software via Mobile Upgrade tool.
