I just got my new device from Garmin - black Index S2. So I made a few measurements and weight looks to be ok, other parametrs I don't know, no other devices to compare. All will be pretty good, if scale could be activated as wrote in guide - by short foot tap. Mostly it don't working and scale stay off. But I discovered that gesture of whole scale like in smartwatches is working. Is this special place on glass where need to tap? In Garmin's clip about scale it all working like a charm, but in practice it is not so cool. Or my copy won't to listen to me?
