First, I would recommend restarting the device.
Restart your iPhone - Apple Support
If that doesn’t work, this sounds like a hardware issue. If the phone has been recently dropped or damaged, that might be the problem. I would recommend making an appointment at your local Apple Store so that they can see exactly what the problem is and how to fix it.
