I have been using my Atom for several weeks and today the sensor at the bottom of the phone in the middle stopped working. I first noticed that I couldn't unlock with a fingerprint so I decided to delete the fingerprint and start again. But it doesn't respond to touch, so I can't shut programs with that button or use the fingerprint device.
