So this is really annoying now. For months the watch has been fine but a couple of weeks ago now I got half way through a run and the watch stopped recording. I use the watches work out app, select running (basic work out) and press start. It records for about 10 minutes and then stops. So a couple of days ago I set the screen to stary on during the run and it was fine for one run. I ran again today and again it stoped after about 2km; no record of the run at all. Any help would be greatly appreciated.
I have been having the same issue for a few months. It appears to cancel my cycle tracking usually within the first 10 minutes. Once it is OK for 30 minutes plus it seems to cope. I thought it might be stopping due to water so set it once to the water lock but it still stopped early so I have discounted this theory. Turning my S3 watch off and on sometimes help but not always.
I just fixed this on my galaxy watch after weeks of frustration. The bad news - You need to reset it. Thew good news - you can just re-download your watch faces and apps again quite easily but more importantly, it doesn't stop during a workout anymore
Even after reset, I had the problem again (I have already reset 4 times the watch because of this).
Today, I had another problem, during the workout (cycling), I paused for some street workout and when resuming the cycling, the distance has remained frozen, but the time goes on. I realized that after several kilometers.
Unfortunately for us, this watch is a shame, sleep analyzing is wrong, I never finished a training and had a complete heart rate analysis.
