Something weird happens to my phone. At times when I am browsing through my apps in the applications window, the phone suddenly goes back to the home screen after about 10-15 secs of inactivity. It vibrates a little bit as if the back button is being pressed. I am 100% sure I am not pressing the back button. Other times, when I start up an app (gmail, facebook, internet, music player, etc) it goes back after about 10 secs of inactivity. It seems to always want to go back to the home screen and it will keep going back till it arrives at the home screen. I just got my phone two days ago and haven't done anything much on the phone yet.
