iPhone XR won't shut off or open apps
My iPhone XR isn't responding correctly. I try to open an app and nothing happens. I've tried to soft reset it and power it off, but the phone just vibrates and doesn't come up with the slider to power off. The side button, volume buttons, and ringer works fine. The screen turns on and stays on until it goes into sleep mode. I've tried connecting it to iTunes but the phone won't trust the computer. Any suggestions?
iPhone XR, iOS 13
