How Accurate Is Samsung Galaxy Oxygen Saturation?

Samsung Galaxy oxygen saturation is a feature on the Samsung Galaxy Watch that allows you to measure the amount of oxygen in your blood. This is a valuable tool for people with lung diseases who need to monitor their oxygen levels.

According to the study by the Center for Evidence-Based Medicine (CEBM) at Oxford University, Professor Lionel Tarassenko and Professor Trisha Greenhalgh reported that there’s no evidence that applications on Samsung Galaxy phones can reliably monitor SpO2.

Although the Samsung Galaxy oxygen saturation app is a handy tool, it is not always accurate.

The root mean square deviation (RMSD) of more than 257 data points derived from the blood sample analysis of 12 human participants was 2.6%.

The performance evaluation of the smartphone pulse oximeter meets the FDA/ISO clearance requirements of 3.5 percent RMSD blood oxygen saturation (SpO2) value for clinical pulse oximetry. This is the first report of pulse oximetry measurements produced from a smartphone that meet all FDA/ISO accuracy certification requirements.

Both the Samsung S9 and S10 are equipped with an inbuilt pulse oximeter; therefore, more than 100 million smartphones now in circulation could be utilized to collect clinically precise spot SpO2 measures to aid in the at-home assessment of COVID-19 patients.

How Does Samsung Galaxy Oxygen Saturation Work?

  • The saturation of oxygen in the blood, or SpO2, indicates the amount of oxygen in the blood. SpO2 is a measurement of arterial oxygen saturation, which is the quantity of oxygenated hemoglobin in the blood.
  • Reading your SpO2 is identical to reading your heart rate.
  • There is a sensor to monitor blood oxygen on the Galaxy Note 4 at home or anywhere else, and you may view your blood oxygen level by making these simple settings.

Procedures for Measuring Blood Oxygen Level (Spo2):

  1. Launch the S Health application on your Note 4. (If it’s not already on your phone, you may get it from Samsung Apps or the Google Play Store.)
  2. If this is your first time launching the S Health app, initial setup is required.
  3. Touch the More icon in the upper-right corner of the display, then tap the Manage Items option.
  4. On that page, you should notice the available health tracker options, such as Heart rate, SpO4, Stress, Blood glucose, and Blood pressure.
  5. Activate the SpO2 item and then return to the S Health main screen.
  6. Scroll down to the list of previously added objects, locate the SpO2 card, and then hit the Measure button.
  7. Place your finger on the sensor, which is located on the back of your Galaxy Note 4, and wait for the measurement to finish.
  8. Remain calm and quiet until you obtain the desired result.

Your measured blood oxygen (SpO2 level) can be saved and tracked over time.


Do I Need A Screen Protector For Samsung Galaxy S10?

The Galaxy S10 has a screen protector that enables access to all touch-screen functions, including the ultrasonic fingerprint sensor.

This two-pack of identical replacement screen protectors includes a microfiber cleaning cloth, dust removal stickers, and a soft-edge squeegee for a smooth installation.

What Are The Specs Of Galaxy S10?

This is not only a new phone. It introduces a new way of considering the capabilities of a phone. Samsung reimagined the phone while you determined the possibilities. Galaxy S7 and S7 edge models. Rethink the capabilities of a phone.


The beauty of what Samsung have designed is that it fits comfortably in your hand while maintaining a large screen size. And the gracefully curved front and rear fit perfectly in your hand. It is as aesthetically pleasing as it is functional.


With a separate game control center and gameplay recording, mobile gaming has significantly improved. With the fast processor of the Galaxy S7 and S7 edge, the game has become incredibly lifelike.


Samsung has redesigned the Galaxy S7 and S7 edge with expandable capacity in mind. Even when everything is operating at maximum capacity, the exceptionally quick processors and enormous RAM keep everything going smoothly. While the larger battery provides longer endurance.

Dust and Water Resistance

The Galaxy S7 and S7 edge are always with you. In the shower, the pool, or the rain. Up to 30 minutes or 1.5 meters beneath. We’ve also figured out how to entirely seal up the interior components while keeping the micro USB ports and earphone jacks accessible, so you won’t need to bother with any additional caps or covers.

Intelligent Switch

Without the photos, files, and data stored on our phones, their value would be diminished. Using the Samsung Smart Switch software, you may transfer everything from your previous device to your Galaxy S7 or S7 edge. It is quite simple.

Samsung Galaxy S9 What Hasn’t Aged Well?

As expected, the battery life is the first aspect of an aging phone to deteriorate, and this phone is no exception. The small S9 with its 3000mAh battery was never a battery champion to begin with, but nowadays it’s difficult to get through an entire day with even minimal usage.

Thankfully, many of Samsung’s service centers provide battery replacements by licensed technicians, which should theory help your S9 last as long as a brand-new phone, though I cannot say from experience.


The S9’s single camera was already subpar when it was released, and it has not improved over time. One UI brings new camera software, but the image processing has the same Samsung tendencies as the Galaxy S20; shadows and color saturation are consistently increased, facial details are aggressively smoothed (yes, even with Beauty Mode disabled), and the slightest subject movement can result in a blurry mess. Additionally, the night mode leaves much to be desired, especially by today’s standards.

Still, it’s not a terrible camera, and while I wish there were options for ultra-wide or telephoto photos, it’s adequate for the task, and Samsung did an excellent job with its manual camera controls, even with its original software.

Samsung Galaxy S9, Two Years On Should You Buy It?

In spite of its challenges, the Galaxy S9 has held up exceptionally well over the past two years, thanks partly to ongoing software upgrades and a wonderful physical design that has not worsened.

It definitely lacks the cutting-edge capabilities of more recent smartphones, but Samsung equipped the S9 with so many physical features at launch that it’s not difficult to picture using it daily in 2020.

The Galaxy S9 feels like a current flagship, especially now that it runs the same Android 10 and One UI 2 software as the Galaxy S20.

You won’t get quite the same camera quality or battery life, but with a price tag of less than $500 today (with used ones widely available for even less), you’re still getting a great value if you get one now.

What Is Good About Galaxy S9?

The Galaxy S9’s iris scanner performs exceptionally well in complete darkness or brightly lighted areas (though admittedly, direct sunlight can often trip it up). Similar to the depth-mapping facial recognition utilized on smartphones such as the Pixel 4, it is incredibly easy to use and effective in nearly all circumstances.

The capacitive fingerprint sensor on the rear of the phone remains one of my preferred methods for unlocking a phone. The sensor is located immediately below the S9’s single camera, which is where my index finger normally rests when I hold the phone.

This makes it simple to unlock the phone without even turning on the screen; however, the sensor is still a bit flush, so a case may be useful for locating it by feel.

Moreover, this rear-mounted sensor offers one of the best features that in-display fingerprint sensors have eliminated. The sensor also functions as a gesture pad, allowing you to lower the notification shade with a simple back swipe.

This is particularly useful for larger phones like the S9+, where it’s difficult to get the notification tray without shifting the phone’s location in your hand, but I adore it on the smaller S9 as well.


The remaining hardware is equally durable. You still get most of the same features as recent Samsung handsets, including IP68 water resistance and wireless charging, however unlike the S20, you cannot wirelessly charge other devices with the S9.

There is even a headphone connector on the S9; personally, this makes little difference to me, as I haven’t used wired headphones in years, but for some, this is a crucial feature.
