I recently completed the reset procedure described earlier in this thread and have now had a chance to test if it has made a difference.   Completed a 1.5 hour, 16 mile ride with auto-pause OFF, screen always-on OFF. No issues with activity tracking ending early. ... View more

Yes, yes, yes!   First thing you should do out of the box with new electronics is charge to 100% without trying to use it.   Li-ion batteries like to be 50%-70% charged for the greatest longevity. Obviously this isn't practical, so we use the battery as needed. But draining to 0% as the first thing to do is a terrible idea. This should only be done as a periodic maintenance every few months to calibrate the software in whatever device you're using to know what 0% state of charge looks like before charging to 100% immideately after. Never leave a Li-ion battery at 0% or at 100% for long or you're going to have serious longevity issues with the battery. ... View more

I was already pretty successfuly using the "screen always on" during a workout as a resolution, but went ahead and followed the reset steps provided by support. Hope it helps! I'll test next time the weather isn't trying to kill me. ... View more

Thanks for the tip, Neil! I just finished a 15 mile ride with no issues using your tips. Here is a sample of my settings. The only settings that matter are within the Samsung Health app on the watch, not the ones on your phone.   On the watch Samsung Health app: Auto-Detect: OFF for Cycling (ON for Walking/Running)   When starting a workout under the "..." menu: Auto-Pause: OFF Screen Always On: ON   Tracked for about an hour and a half with no issues. I was running Strava for tracking on my phone just in case but didn't need to save what it recorded! Very happy to have a complete ride tracked with HR. ... View more

That looks like the version number for the Android Samsung Health app which was released 3/26/2020. I would think that the app installed on the watch with the version number I stated previously would be more relevant to causing/resolving this issue. ... View more

I do have auto-pause turned on and in my limited testing it seems to crash during the pause. Do anyone in this thread have a ticket open with Samsung?   EDIT: Just got in touch with Samsung and it sounds like they are aware of the issue and are working on it. Here is the response I received: "Yes, this is already reported to us and we are working on it as soon as possible. I appreciate you reaching to us to report about this, No worries, we will make sure this will be resolved immediately." ... View more

Thank you for your thorough testing! This is defintely a bug and it started for me recently as well.   I use the watch mostly for tracking cycling. Today's 15 mile ride was split up into 3 "workouts" Workout 1 - 1 mile, started from widget. stopped tracking when I paused riding for 30 seconds. Workout 2 - 6.2 miles, started from widget. stopped tracking when I paused riding for 60 seconds. Got frustrated and resatarted the watch at this point... Workout 3 - 8 miles, started from inside the Samsung Health app on the watch. Tracking did not stop and I was able to complete tracking by "finishing" the workout on the watch.    Somewhere between the restart and starting the workout from the Samsung Health app it seems to have worked better. I'll try it again in a few days.   ... View more
