Ios 16 bug

Same here. I was expecting some hiccups (as every year), but iOS 16 is particularly bad quality. I want to downgrade right now. Anyone know how?

In my case I get this after associating a Focus with a Lock Screen wallpaper configuration:

• Settings - Focus - pick one and delete
• Now I see a frozen wheel on a black screen

what doesn’t work:

• reboot phone - Settings app still unavailable as a black screen with frozen wheel
• swipe up - freezes the entire phone with a dark grey opaque screen, no further inputs accepted
• press side buttons to lock phone, renders control back to enter home, but does not fix lost settings app

all the while the battery drain and temperature of the phone keep rising.

a hard reset also doesn’t recover the situation, really brilliant. I don‘t think Apple tests their product beyond software unit tests. 10 years a customer and it seems to just get worse year on year.

I figured this one out by accident!

A focus selected in the settings app crashes the settings app if you have removed from your device an app which you configured in the focus.

so in my case, I had removed the Reminders app (using 50GB for some weird reason that is not fixed yet). In 2 focus modes I have the reminders app added to permissible list.

when I reinstalled the app, the crashing stopped in the settings app.

not very robust software indeed, but the workaround helps.

Can I downgrade to 15.7?

No
