Troubleshooting
1. Can not turn on the tablet
Check the tablet’s power level, please charge it before starting it. In
case your tablet still cannot be turned on, you may try to reset it
2. No sound from earphone
Check if volume is set to ‘0’. Or earphone may be broken, please
change for another one.
3. Big noise
Check if there is dust in the earphone or speaker. Check if the file is
broken.
4. Frozen to any operation
Please pin the reset hole in the rear side of the tablet, and restart it
again.
5. Screen drift or unresponsive screen
Press and hold the power button for about 15 seconds to force the
tablet to shut down. Calibration will be automatically done after you
start up your tablet. Or you can try to reset it.
6. Application not workable
Possible reasons may be that this app is not compatible with your OS or
the downloaded .apk file is broken so you may need to download a full
version.
8. How delete a Google account?
If an account is added, the account is shown in “Accounts & sync” of
“Settings”, where you may also add another account. To delete an
undesired account, go to “Settings” → “Privacy settings” → “Factory
data reset”. Your tablet’s internal storage, downloaded apps, etc. will
also be deleted, except the info in your flash memory. Be careful before
you carry out this operation.
