iphone xr wont shutdown and cant use apps

Hello buckleycm,

Thank you for participating in the Apple Support Communities! It sounds like your iPhone XR may be frozen or unresponsive and we'd be happy to help with what to do next.

Let's start by forcing the iPhone to restart following the steps here:

Force restart iPhone - Apple Support

"Force restart an iPhone with Face ID

To force restart iPhone X, iPhone XS, iPhone XR, iPhone 11, iPhone 12, or iPhone 13, do the following:

Press and quickly release the volume up button, press and quickly release the volume down button, then press and hold the side button. When the Apple logo appears, release the button.

Let us know if you're still not able to use apps after that.

Take care.
