Oxygen saturation is usually shortened to SpO2, which is a measure of the oxygen concentration in the blood. On many Samsung phones, a series of sensors on the back of the phone can be used to measure Spo2 in a method called pulse oximetry, which can emit and absorb light waves through the blood vessels of the finger.
Samsung has further expanded this feature and even removed it completely from many new phones, but if your device still has the function of reading SpO2, you can perform a beneficial health assessment.
How to measure oxygen saturation
Samsung has eliminated the disposable universal sensors on newer phones still uses the Samsung Health app to measure oxygen saturation. As long as your phone supports it, this is a fairly simple process it is simple to step to measure the oxygen saturation in the blood.
- Open the Samsung Health app.
- Tap manage items, then enable Oxygen saturation.
- Back out to the main screen of the app and tap Measure next to Oxygen saturation.
- When prompted, place your finger on the oxygen saturation sensor on the back of your phone.
- Stay still while your phone is measuring oxygen saturation levels.
After the mobile phone completes the oxygen saturation measurement, the system will notify you that you can pick up the mobile phone from the sensor, and then will provide you with the percentage indicating the oxygen saturation. You will also display your heart rate in BPM beats per minute, and you can click to read information about what SpO2 is and the appropriate steps to get the most accurate reading.
