I own a Galaxy S9+ which has a heart rate and SpO2 sensor.
I can occasionally record my heart rate and blood oxygen with Samsung Health, but I noticed that when I start an exercise, there doesn't seem to be a way to track those vitals during the exercice.
Am I missing something or is it just not possible to do so with the smartphone?
It's not always easy to get your Heart Rate / O² with the S9+ just sitting. It'd be pretty much impossible while exercising.
You'd be far better off getting a watch, or other device that is designed to continuously measure your HR.
Hi, unfortunately it is not possible to measure HR continuously on your phone.
We recommend using a wearable device like the Galaxy Watch Active with your phone if you want to measure your heart rate.
You can check compatible wearables using the steps below :
1.Navigate to and open the Samsung Health app, and then tap Menu (the three horizontal lines).
2.Tap Accessories for a list of products.
