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 can not be turned on, you may reset it before you turn it on.
2. No sound from earphone
Check if volume is set to ‘0’. Or earphone may be broken, please change 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 use a pin to reset and then restart your tablet.
5. Screen drift or unresponsive screen
To correct it, you may a) Go to Settings → Accessibility → Touch panel calibration to
calibrate it; b) In case calibration can not be carried out, you may pull down 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. c) Use a USB mouse to carry
out calibration operations on your tablet.
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 & snc” 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, installed
apps, etc. will also be deleted, except pre-installed apps and the data in your flash
memory. Be careful before you carry out this operation.
