Phones with SpO2 sensor (Which ones?)

In this guide, we will discuss “Phones with SpO2 sensors’ ‘ and some considerations if you are planning on buying a phone or smartwatch to measure your blood oxygen levels. Phones are not only considered for texting or talking anymore, as they were regarded a few years ago, now phones are said to predict your overall health status.

Phones with SpO2 sensor

Here are some of the phones with a SpO2 sensor and heart rate sensor:

  • Samsung Galaxy Note 4 (heart rate, SpO2)
  • Samsung Galaxy S6 and S6 Edge (heart rate, SpO2)
  • Galaxy Note 5 (heart rate, SpO2)
  • Galaxy S6 Edge+ (heart rate, SpO2)
  • Galaxy S7 (heart rate, SpO2)

If you are looking to buy a phone that includes a SpO2 sensor and/or heart rate sensor, here we will mention some of the specifications and additional things to be aware of before buying. However, this is not a complete list of all the devices out there with a SpO2 sensor so if there is a phone you might be interested in buying, make sure it says specifically that it includes a SpO2 sensor.

Samsung Galaxy Note 4

The Samsung Galaxy Note 4 was launched back in 2014. It has a 3GB RAM with a powerful CPR (Snapdragon 805/Exynos 5433). It also has a Super AMOLED 2K high-resolution display and as we have mentioned, it has a heart rate sensor and alsoSpO2, UV, fingerprint and Barometer sensors.

Samsung Galaxy S6 and S6 Edge

Samsung introduced major changes to the Galaxy S6 series back in 2014. The Galaxy S6 Edge was the first phone with greatly curved edges. The S6 and S6 Edge have a 5.1 inches, Super AMOLED 2K screen. It works with Android 5 Lollipop or Marshmallow and it has a CPU of octa-core Exynos 7420 (X2.1GHz+4X1.5GHz). We can find that these devices come with a heart rate monitor, a barometer and Blood Oxygen checker.

Samsung Galaxy Note 5 

After the S6 and S6 edge, Samsung decides to launch another Galaxy Note line flagship, the Galaxy Note 5. Even if the Note 5 is not very different from the previously mentioned devices, it has some differences in respect to the screen size, Stylus, design and RAM. Additionally, it comes with a heart rate sensor, a barometer, front-facing fingerprint and also a blood oxygen checker.

Samsung Galaxy S6 Edge+

As indicated on, “It is a slight improvement on Galaxy S6 Edge. S6 Edge+ comes with a bigger screen, bigger battery and 4GB of RAM. It is like Galaxy Note 5 meets Galaxy S6 Edge. In hardware specs it’s like Galaxy Note 5 while in all the features except for screen size, battery size and RAM, it’s like Galaxy S6 Edge including sensors, camera, CPU, GPU etc”.

Samsung Galaxy S7

The Samsung Galaxy S7 just like its predecessor, includes a 5.1-inch long display, QuadHD Super AMOLED display protected by Corning Gorilla Glass 4. It is brilliantly designed, and it contains a powerful CPU quad-core  Snapdragon 820 / octa-core Exynos 8890, 4GB RAM and 3000mAh battery. 

How can I measure my SpO2 levels?

Here is a step-by-step on how to measure your SpO2 levels if you have a Samsung Galaxy phone, although instructions may vary:

Step 1: Launch Samsung Health on your Galaxy device

Step 2: Scroll down to Stress and tap Measure

Step 3: Place your fingertip on the SpO2 sensor and make sure you stay still while you’re taking the measurement

Step 4: Once done, lift your fingertip from the sensor and you can review your data in the resulting My Stress screen

However, if you can’t find it following the instructions above try using the older method of measuring SpO2 levels by following these steps:

Step 1: Launch Samsung Health on your Galaxy device

Step 2: Scroll to the bottom, tap on Manage items and enable Oxygen saturation if necessary

Step 3: Tap Measure next to Oxygen saturation from the app’s main screen

Step 4: Place your fingertip on the SpO2 sensor and stay still throughout the measurement process

Should I use my phone to check my blood oxygen saturation level?

Pulse oximeters are medical devices that can measure your oxygen levels in the blood, and it is usually measured in medical services or when needed. If you have followed the evolution of the virus worldwide, you may know by now that it is especially aggressive with people who have a weakened immune system and compromised breathing abilities, which makes them have less or lower oxygen concentrations in their blood.

Subsequently, more and more people are trying to find other ways to keep track of their health on their own during these times. Since pulse oximeters are expensive, some people have seen a more affordable solution in getting a smartphone with a SpO2 sensor.

As indicated on, “For years, phone manufacturers like Samsung and numerous app developers have pitched the idea that you could use your phone to measure heart rate and even blood oxygen data, but as the evidence came in that this was not the most effective solution”. However, it is much more frequent these days to see people getting smartwatches with built-in SpO2 monitors to monitor their blood oxygen levels, leaving the smartphones to fade as the primary option for such purposes but, is it truly a good option?

Visit your doctor regularly

Having a phone or smartwatch that measures your SpO2 doesn’t mean that you are exempt from going to the doctor, especially if you have a medical condition. Many doctors will have varied opinions in regards to those devices being the solution you have been looking for. 

Even more so, we can find studies where researchers assure there is no scientific evidence supporting that smartphone technology is the most accurate and secure way of measuring your blood oxygen saturation and even if you find such studies, they will advise you not to trust their data entirely. 

However, you may have a relative or a friend that has recommended a certain device that has been working wonders for them. You may have heard of Fitbit and Garmin, which are brands that offer devices that have SpO2 sensors but you could also find them in Apple watches and other brands. 

Finally, our advice is not to trust 100% in those devices, always consult with a medical professional if you are concerned about your SpO2 readings which could not be accurate.  

Why is this blog about Phones with SpO2 sensor important?

As we have seen, there are several phones with SpO2 sensors, from different brands even if we only mentioned Samsung devices. More and more people are looking for a less expensive solution healthwise and in terms of measuring their blood oxygen levels on the go. However, many scientists and researchers ask people not to trust 100% on smartphones and smartwatches to monitor their blood oxygen levels and recommend listening to your doctor by visiting regularly.

However, we can say that they can be used and interpreted with caution so this means that if you start feeling as if the measurements are not normal or they are a bit odd, consult with your physician as soon as possible.

If your phone does, you can check your blood oxygen levels and heart rate anytime with Pulse Oximeter, wherever you are. You can check your levels when you wake up, relax, before and after exercise, or before a big meeting.

Can smartphones measure oxygen saturation?

No evidence indicates that any smartphone technology is accurate for the measurement of blood oxygen saturation. However, some smartwatch manufacturers in Fitbit, Huawei and Garmin offer a range of devices that have SpO2 sensors, which are said to detect variations in your blood oxygen levels.

Does Galaxy s10 have an oxygen sensor?

The Galaxy S10 is equipped with a sensor that can estimate the amount of oxygen in your blood, or peripheral capillary oxygen saturation (SpO2) and this sensor work in conjunction with the Samsung Health App. However, some of the most recent or newest Samsung phones have done away with this feature.

What is the HRM sensor in mobile?

The HRM sensor or Heart Rate Monitor in a phone is a built-in sensor that lets users measure their heart rate variability. However, more smartwatches have this option included and it is said to be more accurate than phones.

Is your heartbeat unique?

It is said that every individual has a unique heartbeat. This is based on the size and shape of your heart and the orientation of your valves, meaning your physiology. This will not change unless you have a major cardiac event, such as a heart attack.
