Got this second hand google pixel 2 from a seller yesterday while setting up and connected to internet .until I started receiving a notification saying "Device managed by admin - Automatically resetting soon." When I tap on it, it gives me an error saying "Device setup keeps stopping". I checked the phone's IMEI but it doesn't classify as lost/stolen. If I try to factory reset the phone, it asks me for a "@google.com" adress. My question is, should I be worried? Is there any way to fix this?
