Anyone else have any issues with the proximity sensor. I've noticed that unlike my DROID incredible 2, when I pull my phone away during a call the screen doesn't come back on. I assume the proximity sensor would turn the screen back on but I'm not sure if this is just a software issue or if I could have a defective sensor. And right now I have no case and no screen protector and my finger doesn't cover up the sensor at anytime. This is my only issue I've noticed with the phone and any suggestions would be appreciated!!
