I recently got a cheap tablet with an online course, and I want to use it i'n my car's center console as a music player. The problem is that the home screen keeps resetting... When I launch an app and return to the home screen it freezes for a second or two, and then the home screen is reset to how it was when I got it. It also seems to reset every time I turn it off and on again. I already tried to do a factory reset, but that didn't help either... any tips?
