Why is my Razr Maxx making strange noises at night?


AC Question

Strange noises at night

I have a Motorla Razr Maxx with a strange problem: Sometimes, at night, it makes strange notification sounds that aren't associated with any app I've ever used. It sounds like something being thrown. Last night this happened three times. Then, at about 6am, it started playing some guy talking, as if from a radio ad. I had to turn the phone off to get it to stop, but clearly this is not a permanent solution since I won't receive emergency calls. Has anyone dealt with a problem like this before?
