Motion Sensor Not Working
So my iPhone 6s has been working great for the 8 months that I've had it. Now all of a sudden, the motion sensor isn't working. It works to flip the screen in apps like Netflix and Youtube, but for anything else it doesn't work. I've seen videos on Youtube about using the compass app to fix this, but the compass app isn't even registering that it's using a motion sensor.
iPhone 6s, iOS 12
