iPhone glitching after iOS 16 update

I have the same problem, when I updated my phone, there was another update too (15.7) but I skipped that and updated to iOS 16. Can it be the reason of glitching? (mine is iPhone XR)

I updated my iPhone 11 to iOS 16 but keyboard disappears when Bluetooth is on

Apple said that the update works properly only with the original phone displays… Mh:/
