Two days ago(already received a new one under warranty...thank god DFW is close lol) I was using my S4A. I put it in my cargo pocket as I was pulling out of my driveway to go to class. 10 mins later, as I was getting out of my truck, I went to wake the screen to silence it, and nothing happened. My LED was still flashing, ringtones were still playing as I received calls and text messages. I'm just curious really if anyone else has had this issue, or if I should chalk it up to a dysfunctional phone.
