Hello, i just experienced the same thing @abi did. (S9+) Phone said an update was ready, updated, now the phones stuck on the lock screen. I swipe my code, the screen goes black then goes back to the lock screen. An update must have went out because i received one and it said it was an update to Android 10. Unfortunately for me, unlike @abi, i didn’t keep proper backups and have about 5 months of pictures on the phone. Is there anyway to get the phone unlocked or are all my pictures toast?
