When I was sitting downstairs in the den I heard a strange static noise coming from the coffee table and I was wondering what it was. I picked up my cell phone from the table and I noticed that the noise was coming from it. Also the screen keeps flickering on and off. I don't know why it has started doing this because I don't remember spilling any water on it or dropping it. It also turns off after i've left it on for a while. I hope it's not broken.
