If i ever need to use the dialpad while in a call it's really hit or miss. I take the phone away from my ear to use the dialpad and the screen turns back on just fine, but then often turns off as i bring my finger to press a number, and quickly comes back on as i move my finger away. This goes back and forth until i try coming at the screen from a different angle. I actually have to send my finger on a covert mission to avoid the sensor. My finger is never actually over the sensor though. Is anyone else having this problem? Is there any way to adjust the IR sensitivity?
