Does Samsung S9 Has Spo2 Monitor? My Honest Take
Honestly, I’ve spent way too much time chasing down features on phones that just aren’t there. You see the marketing hype, you hear the buzz, and you start to wonder if your current device can do the latest trendy health trick.
So, does Samsung S9 has SpO2 monitor capabilities? The short answer for most people is a resounding no, but the story is a little more complicated than a simple yes or no.
I remember when the buzz around SpO2 on wearables really took off. I’d just bought the S9, feeling pretty good about its camera and screen, and then I saw articles talking about blood oxygen tracking. My immediate thought was, ‘Great, another thing my phone can do!’ Turns out, I was about $300 and a lot of frustration away from actually having that feature on a device.
It’s a classic case of the bells and whistles that sound amazing on paper but aren’t baked into the hardware of older models.
Samsung S9: The Spo2 Question
Let’s cut to the chase: the Samsung Galaxy S9, in its original release configuration, does not have a dedicated SpO2 sensor built into the hardware. You won’t find a little red light or a specific sensor array on the back or side that’s designed to measure your blood oxygen saturation levels. This is a hardware limitation, pure and simple. The technology for SpO2 monitoring, which involves shining light through your skin and measuring how much is absorbed by oxygenated versus deoxygenated blood, simply wasn’t integrated into the S9’s design.
It’s a bit like buying a fancy blender that has settings for ‘smoothie’ and ‘ice crush’ but then expecting it to also churn butter. The internal mechanisms just aren’t there.
Why the Confusion? Smartwatch Echoes
So, if the phone itself doesn’t have it, why does this question even come up? It’s mostly due to the explosion of smartwatches and fitness trackers that *do* offer SpO2 monitoring. Companies like Samsung, Apple, and Garmin have been packing these sensors into their newer wearable devices for several years now. When people see SpO2 features advertised by Samsung, they often assume it’s a feature that trickles down to their flagship phones, regardless of release year.

My own experience here is pretty telling. I spent nearly a week trying to find a hidden setting or a specific app that would magically enable SpO2 on my S9 after I read a few online discussions. I even downloaded a few third-party apps that *claimed* to do it, promising to use the camera flash and sensor. What a joke. They’d give me readings that fluctuated wildly, sometimes suggesting I was anemic at sea level, other times acting like I was training for Everest in my living room. It felt less like science and more like a random number generator.
After about five days of this nonsense, I finally admitted defeat and looked up the specs for the S9 again. That’s when it hit me: the hardware simply wasn’t there to begin with. I wasted probably 8 hours of my life on that wild goose chase, not to mention the frustration.
Your S9 and Health Tracking: What’s Actually Possible
While SpO2 is a no-go for the S9 itself, don’t despair if you’re interested in health tracking. The phone can still be a hub for your health data, especially when paired with other devices. Samsung Health, the company’s native health app, is quite capable. It can track your steps, monitor your heart rate (using the built-in sensor on the back of the phone!), log your workouts, and even record your sleep patterns when you manually input data or sync with a compatible wearable.
The heart rate sensor on the S9, though not as precise as a dedicated chest strap or some newer wearables, is reasonably accurate for general fitness tracking. I used it for years to get a ballpark figure during my runs, and it was good enough for what I needed back then.
Here’s a quick breakdown of what the S9 *can* do for health tracking:
| Feature | Samsung S9 Capability | Verdict |
|---|---|---|
| Step Counting | Yes, via built-in accelerometer and Samsung Health. | Reliable for daily activity tracking. |
| Heart Rate Monitoring | Yes, using the rear sensor. | Decent for general fitness, not medical grade. |
| Sleep Tracking | Manual logging or sync with wearables. | Depends on connected devices or user input. |
| Blood Oxygen (SpO2) | No, not natively. | Requires a separate device like a smartwatch. |
| ECG/EKG | No. | Requires a dedicated device. |
The core issue is that SpO2 requires specific optical sensors, and those simply weren’t a standard feature on phones released in 2018, when the S9 came out. It’s a technology that matured and became cost-effective for mass adoption in smartphones a few years later. (See Also: Does Samsung Gear S3 Classic Monitor Sleep )
The Counter-Argument: Could Software Fix It?
Some might argue that a software update *could* enable SpO2 monitoring. I disagree. While software can certainly enhance existing hardware, it can’t create new hardware functions out of thin air. If the physical components – the specific LEDs and photodiodes needed to measure blood oxygen – aren’t present in the phone, no amount of clever coding will make them appear. It’s like trying to teach a rock to sing opera; it’s fundamentally not equipped for the task.
Think about it this way: the S9’s heart rate sensor works because there are specific light emitters and sensors designed to detect changes in blood flow. SpO2 monitoring uses a similar principle but requires different wavelengths of light and more sensitive detection for a different physiological measurement. The S9’s existing sensors are tuned for heart rate, not blood oxygen.
According to research published by the American Heart Association, accurate SpO2 monitoring relies on specific wavelengths of light (typically red and infrared) and precise calibration. While phone cameras can capture light, they aren’t designed or calibrated for the nuanced measurements required for medical-grade or even reliable consumer-grade blood oxygen readings. The ambient light, camera sensor’s sensitivity range, and lack of specialized LEDs make it an impossible task for the S9.
If You Need Spo2, What’s the Real Solution?
If tracking your blood oxygen levels is something you genuinely want or need to do, your best bet is to look at dedicated devices. Smartwatches like the Samsung Galaxy Watch series (newer models, of course), Apple Watch, Fitbit, Garmin, and others are equipped with the necessary sensors. These devices are specifically designed for health and fitness tracking, and SpO2 is a common feature in mid-to-high-end models released in the last few years.
When I finally accepted my S9 couldn’t do SpO2, I invested in a Garmin smartwatch. The difference was night and day. The readings were consistent, and I could actually trust the data it provided, which was crucial for some training adjustments I was making. It cost me about $250, but that felt like a much better investment than continuing to chase phantom features on my phone.
So, does Samsung S9 has SpO2 monitor? The definitive answer is no. But that doesn’t mean your S9 is useless for health tracking; it just means you need to be realistic about its capabilities and consider pairing it with the right companion device if SpO2 is a must-have for you.

Can I Use My Samsung S9 Camera to Measure Blood Oxygen?
No, you cannot reliably measure your blood oxygen (SpO2) using just your Samsung S9’s camera and flash. While some apps might claim to do this, they lack the specialized hardware and calibration needed for accurate readings. The results are typically unreliable and should not be trusted for health-related decisions.
Does Samsung Health App Support Spo2 Tracking on the S9?
The Samsung Health app itself can display SpO2 data, but it requires a compatible wearable device that has a built-in SpO2 sensor. The S9 phone itself does not collect this data, so the app cannot show it for the S9 alone.
Are There Any Samsung Phones That Do Have Spo2 Sensors?
Yes, newer Samsung Galaxy S and Note series phones, as well as later Galaxy Watch models, have incorporated SpO2 sensors. For example, the Galaxy Watch 4 and newer, and some S-series phones released after the S9, have this capability integrated. Always check the specific model’s specifications before purchasing.
How Accurate Are Spo2 Monitors on Smartwatches?
Generally, SpO2 monitors on reputable smartwatches offer good accuracy for wellness tracking and identifying trends. However, they are typically not considered medical-grade devices. For precise medical diagnosis or monitoring, always consult with a healthcare professional and consider medical-grade equipment.
Final Verdict
So, to bring it back around, does Samsung S9 has SpO2 monitor functionality? The answer, as we’ve established, is a pretty firm no. It’s a hardware limitation, plain and simple, and no amount of software wizardry can change that.
If you’re looking for blood oxygen tracking, your S9 isn’t going to cut it. You’ll need to consider a newer smartphone model or, more practically for dedicated health metrics, a smartwatch or fitness tracker that explicitly lists SpO2 as a feature.
Don’t let marketing tempt you into believing older tech can do everything newer tech can. It’s a lesson I learned the hard way, and one that saved me a lot of head-scratching down the line.
Consider what health metrics are truly important to you. If it’s basic activity and heart rate, your S9 might still serve you well, especially when paired with Samsung Health. But for anything more advanced like SpO2, it’s time to look at your options beyond that specific model.
