For the past week, after some reset on my galaxy active, my hear rate monitor isn't working properly. Don't work automatically and when I send manually goes like 85% of the process, flashes the green light on the back of the watch and keep track of my heart rate on the screen but tells me that wasn't able to measure my heart rate and to try again later.
Tried almost everything on my smartphone and on my watch regarding configuration but it keeps having this issue.
My Phone is a Galaxy S8 Plus and firmware and apps are up to date. Same goes for my wearable that hás been updtaed by Galaxy Store. It seems that pedometer is not working properly as well.
I've already done restore but don't know if is the same as factory reset. Done that both on Phone and watch. Since then this problem started.
Also following this link the method for restoring is not working on active.. The message rebooting appears but after that restart normally
My bad! You can do this on the Galaxy Watch Active by following these steps:
On the Apps screen, tap (Settings) → General → Reset. Before performing the Factory Data Reset, remember to make backup copies of all important data stored in the Galaxy Watch
If the issue still there after a Reset and everything is up to date, I will encourage you to get this examined by one of our engineers to see what is causing the issue. Locate your closest one from here: https://www.samsung.com/uk/support/service-centre/
