You cannot start the measurement at any given time and there is no history whatsoever. A most pathetic move from Samsung. Clearly shows how much they care about their customers.
Samsung... in a moment of great needs for a worldwide COVID-19 pandemic emergency you should really open up the feature of measuring SpO2 for all the enabled devices everywhere in the world. I am trying to measure the oxygen level of my old parents that show some symptoms, the Emergency dept. and intensive care units are already full. This feature could make a difference in chances of survivability if I am able to bring them being diagnosed in time should the app report unusual oxygen levels.
So please... PLEASE, open up this functionality. Get it back! The world needs your help.
To all of you wanting to gain this feature back, since Canadians don't have the "stress test" and Samsung doesn't give us any help. This is especially critical for covid measurements. Here's what you do.
Go to your Samsung health icon. Uninstall it. Then go here https://www.google.com/url?sa=t&source=web&rct=j&url=https://www.sammobile.com/apk/samsung-health/sa... and download the apk (it's an older version). After it's installed, go to your Samsung apps and turn off "auto update".
Use the app as you did, your SpO2 function is back!
Please put it back, especially now. That way I don't have to take a pulse oximeter with me. I can also trend the 02. Trending whether I am under stress is not as important. You can see that in heart raises or, sometimes 02 drops.
I am an apnea sufferer and have problems at altitude, please bring it back!
