Google account help needed
Hi all, I recently purchased a truck that has a Joying 10.1 tablet deck receiver installed. When I try to download apps or access Google, it keeps trying to log in with the prior owner’s account and will not let me add mine. Any ideas how to get it to forget his and add mine would be appreciated! I have been trying everything I can think of and searching online but not having any luck. TIA!!
In the Google ssettings you have the option "Add other account".

But the best and most simple one is to "reset to factory defaults".
In that case all accounts will be removed and what has additionally been installed by that user.
