Recently I have discovered that literally all sensors on my Note 4 suddenly stopped working. This include the proximity sensor as well as the gyroscope sensor and GPS, etc.:
How can I fix it? Why is it happening? I haven't tried performing a factory reset because I don't want to do that unless it's necessary. Now the screen won't turn off during a call, and the GPS doesn't work in Google maps. I can't even shoot videos in landscape.
This phone is not rooted. Running on Android 5.0.1.
