The floor counter on my galaxy watch has always worked pretty well, maybe a floor out here or there. recently the thing has gone nuts, I cant quite remember if there has been a recent update or not but for the past few weeks my average floors for the days have been around 80 on my watch. I wake up in the morning and have climbed around 15 floors in my sleep. I have factory reset the watch, connected it to different phones, changed the watchface, played with the altimeter. the step counter is still working fine but the floors is CRAZY.
