Ive been using the o2 sensor for o2 sat since the s7 edge , s8 ,s9 n now the s10. In the s10 i believe samsung has used a faulty sensor if u press the sensor with slight pressure it would read o2 sats of below 90% with barely touching the sensor it seems to give better results but never more than 98%. Tested side by side with the older s series phones. And then they have now removed it as a standalone feature of samsung health wen infact they used the o2 sensor as a selling point on the older models. It looks more like a cover up and they are trying to prevent people from getting aware of the issue with the samsung health update. Perhaps they are trying to avoid recalls of their new flagship. Id dare them to prove me wrong.
