Anyone else with the latest update can inform us?
As said I got a Fenix instead and although it's a great fitness companion, I still miss the galaxy watch so fingers crossed regarding the HR sensor.
Can you give a little more detail on how you got it to work. If i understand AOD it means always on display? I turned that on in my settings, and while the display stays on during my workout the widget for Samsung Health still goes to sleep. Which I believe is the main issue. The heart rate monitor its self works perefectly. I was at the doctors and the device they put on my fingure matched my watch HR exaclty. So I agree with what most said its the Samsung Health app. After reading your post i started paying attention, at Orange Theory when i'm on the rower my arms position causes the widget to be up longer so during that period it reads my HR more accurately. But when I'm doing weights or on the tread it switches back to the time on the watch. Did you figure out a way to keep the workout up on your watch during your workout? or did you just use the 'always on' setting ? OR did you use a specific watch face type ?
The problem in my humble option is not with AOD but with the HR sensor itself, or more precisely the software interacting with it. I can only assume its the Health App as other 3rd party apps seems to work well with Tizen/Galaxy Watch.
I've posted before but to recap, on Gear Tracker it reports the sensor as being restarted for example 29 times in an hours workout, HR during this workout is 95% spot on. The Galaxy itself or Samsung Health doesnt have the ability to restart the sensor immeditely on failure hence the flatlining and break in HR when looking at data whether on the Watch or in S Health.
Next time you workout and it freezes, quickly switch back to the watch face (with HR icon on) and you may see the HR is actually working OK, just that Samsung Health cant see it..
Just my inout for what its worth
New update came out. Maybe someone can test if Samsung sorted out these problems with it ?
(I don't own the watch anymore since I returned it after seing that HR doesn't work correctly)
