It's hard to explain what in the hell is happening with this phone. Here's what it does, when you turn on the phone, it goes through its usual process of booting up. After booting up, and at least use the phone for ten second, the phone's screen turns off, the phone vibrate for one time, the screen comes back on at the lock screen, vibrates 3 times, and it repeats this process forever. I had a video for you to see what the phone was doing, but im a new user. so i cant show you the video on youtube. ill probably put the video in a zip later on tonight.
