Troubleshooting .................................
Before contacting the service centre, 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 on 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 Updats, touch the Application tab from the Home screen,
then select Updats 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 software
version. You should turn on data connection or Wi-Fi before searching for
updates. Auto-check settings are also available. 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 the status bar.
Don't change your default storage location while FOTA is downloading or
