When I'm laying down and turn my wrist to view the watch, nothing happens; the screen doesn't wake. Even with a very very deliberate movement of my arm it won't activate. In fact the only way to activate the screen while laying down is tapping it. But when sitting or standing it works perfectly. Strangely enough it works perfectly even when my arm seems to be in the exact same position as it is when I'm laying. It was doing this to some degree since I got it, but now it never activates while laying. What the hell is going on!? I'm tried restoring the watch, resetting it etc. No change.
