Hey redd1999,
Thanks for the question. Have you tried restarting or resetting the iPhone? If not, let's definitely give both a whirl:
Turn your iOS device off and on (restart) and reset

If the issue persists after a restart/reset, let’s see if we can isolate to software or hardware by backing up and restoring your device as new:

After erasing and setting up as a new device, your device is now in a factory configuration. Test to determine if erasing and setting up as a new device resolved the issue. Content on the device may have caused unexpected behavior.
If the issue is still present, you may want to contact Apple Support.
