If the steps above doesn't help, the next step we can try is to restore the iPhone and set it up as new to test.

You'll need a computer and a cable to do this.

It’s an iOS 16 issue. Had everything in my phone replaced, screen, rear system (which is all sensors, motherboard, battery, etc…) and the issue persists. Apple is yet to formally acknowledge it, I wasted 3 days at an Apple Store trying to get it fixed…

Find a way to downgrade to iOS 15 or sell the phone 😅 - more seriously I can only hope they will release a bug fix update soon that covers this issue. I’m still disappointed and expect better from Apple.

They’d need to use a proprietary flashing tool (which will likely erase your data) and this is assuming this tool exists. The only other possible way is rear system replacement in the hopes that they have old stock of rear systems that haven’t been updated to iOS 16.
