Blood Oxygen sleep monitoring

[Nickh101]

Has anyone had a problem with the oxygen monitor not working while you're asleep. 

I can't get it to monitor me while i sleep at all on my new Galaxy Watch 4. 

Bugging me i have to say. 

As far as im aware its correctly fitted on my wrist and can take a reading anytime using the watch and its turned on in Samsung health to monitor while sleeping. But not a single night has this worked yet. 

UPDATE.... 

You will be pleased to know I've just installed a new update this morning on the watch and the option to turn on blood oxygen monitoring is now in the settings for samsung health on the watch...

In the UK with Samsung Watch 4 4g no update available so the option to turn on Blood oxygen monitoring isn't available.  Please raise with Tec support to solve issue
