you will have to reset your phone to factory default which will erase all data on your phone. you then have to start from scratch with a new GOOGLEPLAY android card and a new email address for it. If that does not restart your phone, then you will need to buy s new one. I would recommend you buy the SONY XPERIA brand or Wyliefox which is a British brands my mates have them with no problems. go to settings app on your phone and click on factory reset. My Samsung J3 2017 phone will not yet update android 10 software, they are 12 months behind, I wont be buying another samsung phone because of this problem, they just want users to keep buying their newer phones every 2 years when my knee I bought in 2017 on 4G still works fine, they are getting as greedy and worse than APPLE and Nokia for failing to update the latest android operating software!
