Hi, I've had my X for 3 days, upgraded from HTC Eris - trying Moto due to signal issues in my area. I read (sorry can't find it to post there) about the screen going black during phone calls related to a sensor in the phone. Mine doesn't go black. I started searching for ways to keep my face from beeping, muting and hanging up on people. I almost returned the phone day one thinking I'd dropped 3 of 5 calls. Is this something that is missing in my phone. I did the hold the finger over the area of sensor as suggested by a poster - no blank screen appeared. What is this little droid talking about when it tells me I can see the widget gallery and launcher pro? How do I find this? Thanks for any replies. I like to know what I should know prior to talking to customer service or in store reps so I get right answers.
