Troubleshooting ...................
Before contacting the service center, you are advised to
follow the instructions below:
• To have optimal operation, fully charge the battery.
• 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.
• To set your phone to factory default, use the Backup
& Reset in the phone’s settings. All your phone data
will be lost permanently. It is strongly advised to fully
back up your phone before resetting.
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.
• Check that the charging port is secured and not
damaged.
