Need to know if this is a bug or what! When I make a call, regardless of using speakerphone or holding the handset to my ear, the screen goes blank repeatedly during the call. This is not correlating with the screen time-out choice I have set (which is currently 2 minutes). For example, if I call a toll-free # and have to enter information on the dialpad at the automated prompts, I have to tilt the phone front to back to get the screen to come on again so I can see the dialpad to enter the numbers required. Again, this happens regardless of whether speakerphone is on or off. It's quite annoying to say the least, when I have to enter lots of things via the dialpad and keep tilting my phone just to do this. I also have to tilt the phone to get the screen to come back so I can use the end call slider. Do I have a bum Transform?
