Ok that makes a lot more sense. As the guy said HTC don't do a good job of communicating these features, the advert shows a guy falling asleep and as he shuts his eyes the phone locks... I have never actually had this problem though generally I can read a screen full of text before the phone locks. My scrolling will reset the lock timeout. Videos and games stop the phone from locking.
