I've been using Samsung gear sport watch for more than a year and been using Galaxy watch for almost 8 or 9 months.
One thing, i noticed on both of my watches that they keep counting steps while I'm driving a car.
For example, if I've walked 5000 steps and then start driving my car, after around an hour, it displays more than 6000 steps.. (means it adds almost 1000 steps to my already taken steps for an hour's driving)
Same goes for the floors. If i climb 4 floors, it counts 6 floors.
inside car it can count steps for bumpy roads because jerking measured as steps..but no idea about stairs...I observed in my device that,pedometer takes to count after 1 or 2 seconds..means it can skip 3 or 4 steps which is negligible but you observing extra steps when climbing thats have no idea
no it's not possible because sensor made up of such a way that related to device movements with some vehicles or human...as an example if you put a steps then little jerking detecting as steps same when you are traveling too
