my phone was stolen and got back again after complaining to the police. it is Samsung Galaxy J7 (6). Factory reset was done by the thief. i am not sure how my device has been removed from my google account. after the factory reset i am trying to restart my phone using my google account and i enter my google account and password. now it says "unable to sign into due to a unknown error. please try using another account or try after 24 hours."
what is the solution?
