Greetings! I just switched to the HTC Droid Inc 4g from my Blackberry dinosaur two weeks ago, so I'm pretty new to Droid. I love the phone for what it can do at my work place, with exception to phone calls. I hope I'm just missing something and this isn't a hardware/software issue... After I answer or dial a call, the screen goes dark without it being near my face or my finger. The only way I can hang up is to hit the power button which brings the screen alive, therefore allowing me to hit "End". It gets really annoying when I have to enter in prompts and the screen keeps locking on my mid-way through entering my cc number . Other times, the screen stays on for the entire call, never going black when I bring the phone to my ear. Everything I've experienced thus far screams a proximity sensor issue. At first I thought I could live with it, but occasionally I see the little red light to the right of the logo powered up and I can't help but think it's sucking battery power. Just for verification, this is the prox sensor, right? Btw, I have no screen protector.
