Wrist gesture since update 21.00

Not "always on" for me.  Did you check your settings?

system > backlight > During Activity > Timeout (I use 8 sec, but perhaps you have it set to no timeout?)

I set it so it should turn on only when a gesture is detected, but it's detecting a movement 90% of the time.

Previously, it was turning on only when I moved my arm to look at the clock

I realized that afer 21.00 update, gesture backlight works fine during interval training. I twist my arm to look at the watch and backlight is on. I twist it back to normal running position, and it is turned off.

But for any other activity than interval training, the twist of my arm is wrongly detected and backlight is always on

I've noticed the same thing during a run activity.  I try to turn it off, but it comes right back on.

Did you check the separate backlight settings for Not During Activity? And perhaps change them, then change them back to what you what.

(Apologies if this is obvious, but I thought I'd mention it for completeness).

Problem stays with the new 23.00. All time lighten.

and still in 24.10
