    Not sure if this has already been covered here but I found the "Activate on Wrist Raise" behavior not 100% reliable until I realized the algorithm is looking for the arm to be horizontal before doing the wrist turn towards you.

    If your forearm is at an angle it frequently doesn't trigger.

    So make sure your forearm is horizontal before you turn your wrist and it is 100% reliable. Takes about 10 minutes to refine this action and it becomes habit after that.

    Try it.

    Read.

    OP already elaborated. #

    you're wrong. my arm is literally at a 45 degree angle at the moment and when i turn the wrist the watch face activates.

    Bob Newhart executes this perfectly at about :54 seconds into the Main Title sequence:

    And it was much, much harder for him, what with Jony Ive being only five years old and Tim Cook being only 12 at the time and the prototype was very crude.

    agreed - mine activates at an angle as well, does NOT need to be horizontal

    Are people having trouble getting it to trigger? Works for me virtually 100% when I'm sitting upright or standing. When reclining, I sometimes need to touch the screen or tap the crown (expected).

    Try the horizontal arm technique. When you're laying down your arm is often at a weird angle. Report back if it helps.

    I've said this before, but Casio's have had an "auto-light" feature for at least 10 years, which seems similarly unreliable. I can't believe Apple couldn't perfect this after all this time.

    I'm not sure of the science behind it, but I've gotten very good at getting the screen to activate with minimal motion of my arm. It just takes practice and eventually muscle memory takes over.

    Nah, can't be more perfect than Apple as of right now. :D

    After wearing the Pebble since it launched my "wrist raise" instinctively includes a "flick" even when wearing a normal watch. Haven't had a problem thus far because of that.

    (The pebble backlight turns on with a wrist "flick.")

    That clearly isn't a wrist raise. You're just rotating your arm.

    Well, booo-urns to Apple's specific wording. #

    Wish it worked on a wrist-turn....

    Twist your wrist. I can make mine go on consistently without raising my arm at all.

    Only Apple products can get us to change the way we use our body parts.

    I think Apple can learn a couple things from Casio. My calculator watch has an 'auto light' feature, that automatically turns on the light when I check the time. It's actually quite good at knowing when I want to look at the time and when I'm just moving my arm around (walking, etc), to avoid false positives.

    Just took a quick vine:

    Works fine for me with that same motion, so maybe your accelerometer is out of wack, or just not as sensitive.

    I don't know why, but I've always loved Newhart. I wasn't even born until it was almost off the air, but I still like it. :)

    It would be good if you could increase the sensitivity if you judged your battery life could take it based on your use of the watch

    I'm usually left with >50% battery life a few false screen activations would not kill the battery too much but reduce my frustration considerably

    I'm doing the same thing and it's activating mine.

    OP is right. it doesn't always happen but i have noticed this when sitting on the sofa leaning on my left arm (With the watch). some time it doesn't register unless my arm is parallel to the floor.
