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!
Samsung has missed a trick with me .I have bought every thing off Samsung including watches for me and me with .I'm talking about every time a new phone comes out we have it ..we now both have the Note 10+ and must say I'm am very disappointed they have removed the O2 sensor which right at this moment we needed .They are removing no adding stuff to the phones including the long gone IR blaster .All I can say Samsung just ordered 2 X Huawei GT2e watches and now looking at changing over phone too .
Can somebody confirm this, but I thought that the Note 9 was the last Samsung Galaxy phone with an oxygen sensor included.
Also, the oxygen sensor on the Note 9 appears to be a lot less accurate than on previous models. I read in another forum that placing your palm over the oxygen sensor is better than the finger, and I found that to be much more accurate & reliable... It now gives results very similar to my Note 4 and my real oxygen sensor.
