Okay this is incredibly annoying. My Captivate locks while I am in a call. If I pull the phone away from my ear, the screen will stay blacked out until I press the power button. For a split second, the screen shows locked then automatically transitions to the phone UI. Even if I use speaker phone, the phone eventually locks and I must depress the power button to end the call or dial other numbers. Is this normal for this device? I previously owned the iPhone 3g and the screen would black out, but would come right back on when you moved the phone away from your face or if you just shook the phone a bit. Any info or recommendations would be much appreciated. Thanks!
