Hi I am using the Samsung galaxy S23 ultra it's a great phone. There are however a few small problems I use a talking clock App and in power save mode it doesn't work even if you grant it permission. I bought a screen gard for Samsung at first I was very disappointed I couldn't get my fingertips to read. I wasn't going to give up most of my App requests it. All you need to do to overcome this problem is to delete all your finger prints that you made before you put on the screen gard and reinstall them after you put on the screen gard.
