iOS 16.1 update

There seems to be major issue with the ios16.1 update. Since last midnight when the phone software was upgraded there is a major issue of making and receiving calls. I am not able to hear any voice after 12 secs into conversation. It is not a network issue.

the wallpaper has stopped shuffling when I added more pictures.

rest of the issues will be reported as faced. Kindly sort out the issue. I think the update is not fully compatible with iPhone 13
