I installed last update and now my only phone is useless!! I can’t make even a phone call. No apps will open and I can’t even restart it. I tried the suggestions and nothing. If you don’t update you constantly are reminded, which I try to ignore as my phone was working fine now it is useless!
Unable to do anything with my IPhone 12 after last update
Which update ? Beta or release ? You should never install a beta on a principal device. If it is a release, contact Apple support.
