o2 saturation rate measuring capability with S21 Ultra?

[userWw5rphV0JL]

Does anyone know if the galaxy S21 ultra has the ability to check my (o2 sat)- oxygen saturating rate.  It has an option in Samsung health but it's not letting me turn it on. I was able to use it on my older Samsung phone all the time. Please help if you know.  Thank you.. Kevin

It doesn't have the sensors, so no you can't. The last Samsung phone to have that was the S10

Thank you very much Tom. I figured with 4-5 camera lenses on this phone one of them might have been an o2 sensor. I'm on oxygen 24/7 and you've been a big help. Hope you have a great day. Kevin

The Galaxy Watch 3 and 4 both have O2 sensors.

Oh great, I've been debating on getting a smart watch and didn't think about a smart watch having an o2 sensor. Thank you Oxford and have a blessed day
