Before contacting the service center, you are advised
to follow the instructions below:

To improve the phone’s performance, remove
unnecessary files or apps on your phone.
•
To update your system software, use the System
Updates command in your phone’s settings.

My phone can't be switched on
•
When the phone can't be switched on, charge for
at least 10 minutes to ensure the minimum battery
power needed. Then switch it on again.
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 re-insert it, then restart the phone.
My phone turns off by itself
•
When your phone turns off by itself, make sure
that the Power key is not accidentally pressed.
•
Check the battery charge level.
•
Check your phone’s settings for turning off the
phone at a certain time.

If it still doesn't work,
Factory
reset the phone via
the Backup & reset in the phone’s Settings. Make
sure you have backed up your data.
My phone can't charge properly
•
Make sure that you are using the proper charger
that comes with the phone.
•
If your phone has a removable battery, make sure
that your battery is inserted properly and the
battery terminal makes good contact with the
phone. It must be inserted before plugging in the
charger.
•
Make sure that your battery is not completely
discharged; if the battery power has been
discharged for a long time, it may take around 10
minutes to display the battery charging indicator
on the screen.

Make sure that charging is carried out under
normal conditions (0°C (32°F) to 55°C (131°F)).
•
When abroad, check that the voltage input is
compatible.
