Stupid iPhones with their extra text message reminders.
I thought you used a Samsung S9, like mine.
My cell adds some new bloatware with every update.
I just got this "safety" feature to prevent butt dialing which I do not need. This latest annoyance locks the screen until you swipe it the way it likes, so we are all better protected from accidentally touching our screens.
I haven't gone to find this thing and kill it yet, but soon.
