Its funny that you posted this, because the first day that I bought mine, I was changing a song on my phone and the laser alert on my whistler radar detector goes off so I drop my phone and slam on the brakes. I don't see a cop so I pick it up to change the song again and suddenly realize that my phone is setting off the laser alert. There are 4 infrared lasers located at the corners of the phone. They are for motion, detecting when you swipe your hand above the phone. If you record your phone (with a different camera) you'll see the infrared lasers flashing in the corners.
If you want the laser alerts to stop, go to settings, moto, and turn off the actions (reach for screen... And the other 2)
