This feature has been available on the 935 for a while now....
Hold UP during activity > Run Settings > lap key > off
Which firmware/region is your 935 on?
Anyone know how to turn off the manual lap button on the 935?
I wish the up/down buttons were on the right instead of the left.
The Lock Keys and Auto Lock settings ought to disable it (and more).
Would it help to wear your watch on the other wrist, such that the orientation of what is on the ‘outside’ edge (closer to your wrist) and what is on the ‘inside’ edge (closer to your elbow) are reversed?
Auto Lock really isn't a good option for me
The best option by far is not to press the wrong button in the first place.
