14 Troubleshooting
Before contacting the service center, here are some instructions to help
you troubleshoot your device:
• To have optimal operation, fully charge the battery.
• To improve the devices performance, remove unnecessary files or apps
on your device.
• Update your device’s software via the Updates application. Or you can
touch Settings > About tablet >Software Updates to update software.
• Reset your device via Factory data reset. You can touch Settings >
Backup & reset > Factory data reset, and then touch RESET TABLET.
Another method is to hold down the Power key and the Volume up
key at the same time when your device is powered off. All your device
data will be lost permanently. It is strongly advised to fully back up your
device data before resetting.
and carry out the following checks:
My device can’t be switched on or is frozen
• When the device 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 device falls into a loop during power on animation and the
user interface can’t be accessed, press and hold the Volume up key to
enter Recovery mode. This eliminates any abnormal OS booting issues
caused by third party applications.
• If neither method is effective, reset the device using the Power key and
the Volume up key (holding both together).
My device has not responded for several minutes
• If your device doesn’t respond, turn off your device by pressing and
holding the Power key until it turns off and then restart it again.
• If it still doesn’t work, reset the device.
My device turns off by itself
• Check that your screen is locked when you are not using your device,
and make sure that the Power key is not accidentally pressed while the
screen is unlocked.
• Check the battery charge level.
• If it still doesn’t work, reset the device.
