Iphone XS Max freezing after IOS 16 Update

Hello Caligrafix,

Welcome to Apple Support Communities!

We want to make sure your iPhone is working perfectly for you.

To learn more bout the freezing, does this happen in all apps or only certain ones?

Installing pending app updates can help resolve a software related app issue. Use these steps to check for updates: How to manually update apps on your Apple device - Apple Support

"How to manually update apps on your iPhone or iPad

1. Open the App Store.
2. Tap your profile icon at the top of the screen.
3. Scroll to see pending updates and release notes. Tap Update next to an app to update only that app, or tap Update All."

Let’s also try a normal restart to see if that helps to quickly resolve this. Our Apple Support page has the proper steps if needed: Restart your iPhone - Apple Support

"How to restart your iPhone X, 11, 12, or 13

1. Press and hold either volume button and the side button until the power-off slider appears.

2. Drag the slider, then wait 30 seconds for your device to turn off. If your device is frozen or unresponsive, force restart your device.

3. To turn your device back on, press and hold the side button (on the right side of your iPhone) until you see the Apple logo."

We hope this helps to resolve the issue and get the iPhone working perfectly again on iOS 16.

Cheers!
