15.7.3 iOS update made iPhone SE (1st gen) useless
The 15.7.3 iOS update which autoinstalled essentially soft bricked my child's iPhone SE.
You can log in, but the UI freezes frequently for 30 seconds or more and normal actions like FaceTime and sending messages do not work or cause crashes.
Backing up the phone to a computer does not work, phone shows up erratically in Finder.
Restarting helps momentarily, but freezing issues appear immediately e.g. if opening messages.
Is there any fix for this? Apparently the update cannot be rolled back. Tried setting up their account on another old iPhone SE, but that also forced install of 15.7.3 – remains to be seen if that phone becomes soft bricked as well.
