Hi @tedony ,

Try starting the tablet in safe mode and check if the problem is still there.

If not then a downloaded app is the cause of the problem.

The trick is to find out which one.

Hi @tedony ,

Try a factory restore (also known as a hard reset) and check if this resolves the problem.

BACKUP the tablet BEFORE performing a FACTORY RESTORE as it will ERASE all your data and downloaded apps.

Once the backup has been completed perform the factory restore using the tablet’s factory restore feature.

Once the factory restore has been completed check if the problem is still there or not.

If still no good then you have a hardware problem.

If the problem is not there anymore, restore the tablet with the backup that you made earlier using the tablet’s restore feature.

Once the tablet has been restored to what it was before, check that it is still OK.

If so, then the reset has resolved the problem
