Reading only the title, I thought "I am having this problem exactly now!". However, it is not about lack of security updates (it's an old Motorola phone). It is a smartphone that belonged to my late father who passed away in 2020. He had a google account with password and the phone has a pattern to draw in the lock screen. I know Google and the phone manufacturers are concerned with the stealing of phones, so they make it as hard as they can to use a phone without authorization, even if you try to reset the phone and erase all user data. Does anyone know if there is a process to remove a google account from a phone even if I have to prove to Google that he died of natural causes?
