I've noticed that (besides covering the screen with your palm) you can turn it off by rotating your wrist away from you, which is normal, like the screen going off by putting your arm down. I have Raise to Wake off, screen timeout at 15 sec. That being said, sometimes when I do that my screen wont go off right away. It takes a couple times. Same goes for the covering it with my palm. It only happens every once in a while and I noticed it's usually after a notification or swiping up the control panel from the bottom. Has anyone else noticed? I did put a screen protector on my watch and don't recall this happening prior to that so maybe that's what it is. I guess the only way to test that would be to take it off but I figured I'd see if anyone else noticed the same or had the same happen (or any other weird things a screen protector might cause) before I do that so I could maybe avoid having to buy another one.
