My elderly Mom has a Galaxy A15 (Android version 14). She currently has ONE UI 6.1 installed on her phone. She pushed the update on Tuesday (to update to One UI7) and after it completed it totally locked her phone up. She couldn't even use it, it would BRIEFLY show the home screen, then a pop would come on for some games and I couldn't get it to close. I ended up having to run it in safe mode and un-install the update so that I could get it back operational. But I never could find (under apps or anywhere) this gaming ad that kept coming up. I'm afraid to re-install the UI7 update that it will do it again and I won't be able to get it fixed. Anyone else had anything like this happen and if so, should I install the update, or wait longer?
