My samsung galaxy watch sensor on back stopped flashing and now wont detect my sleep or heart rate

[Members_JEf0JfV]

Hi my Samsung Galaxy watch has suddenly not letting my sensor work on the back. Therefore it's not picking up my heart rate or sleep. Any ideas tried every suggestion in settings still nothing. I've cleaned the sensor put it right on wrist but still no flashing green light.

Have you tried switching it on and off? Do you have battery saving modes of any kind selected? Updated to the latest firmware? If nothing else works try factory reset. Otherwise you may need to claim under your warranty.

I tried all the options still not working.After factory reset also same issue. Is it software or hardware issue.beacause watch is not physically damaged it stopped working by itself

We have 2 watches with the same problem both initially stopped working on the same day which to me indicates a common issue.
One of them has started working again (although it has stopped briefly since and restarted). The other refuses to detect the heart rate.
We have tried all of the obvious uninstall, reboot and reset options without success.
Any ideas?

Same here.  So much for tech support.

Same problem for me.  It followed the watch overheating and not charging.  That resolved, but then the HR sensor stopped working. No flashing light and not fixed by turning on and off, nor factory reset.

The same thing happens to me. It's not the first time it's happened. Once, it didn't work for a whole year, and then it magically started working again.
It stopped working last week.
