Samsung Galaxy S21 has officially launched and available on the market for quite some time. It’s another superb device from Samsung with a lot of great features. Not only features, but compared to previous Galaxy S iterations, this time Samsung choose a rather bold design to show case (or to show off) the rear cameras on Galaxy S21. Having both great features and design and being a Samsung flagship, it makes Samsung Galaxy S21 to be the popular target for counterfeiting.

Now if you are reading this article, it’s very likely you are interested to get Samsung Galaxy S21 but for whatever reasons, you haven’t got one in your hands or you have got one but a little bit pessimistic whether you are holding the original or fake one. That’s the reason why I’m making this article, to help people (like you) to differentiate between the real Samsung Galaxy S21 with the fake one, so that people won’t get trapped buying a fake Galaxy S21 and paying the real price for it.

If your main intention to go and buy the fake Galaxy S21 and pay it for the fake price, then it’s totally fine. You are getting what you are paying. However, there are out there, casual non-geek people (you may be one of them) who may get deceived by other people / organizations, where these people intend to buy a real Galaxy S21, willing to pay for the real Galaxy S21 price, but they are getting fake Galaxy S21.

Don’t just leverage on Benchmarking application, such as AnTuTu or 3DMark or Geekbench, because based on my own experience in the past, these apps can be cloned and tweaked to show fake device to show like a real one. Use these methods instead, to ensure you are getting the real Samsung Galaxy S21.

How to check if the Samsung Galaxy S21 5G / S21+ 5G / S21 Ultra 5G is the real one.

In today’s highly advance technology and interconnected world, it’s not difficult for a small company or even individual to create and market a fake or cloned smartphone. Being a flagship and a popular model, Samsung Galaxy S21 5G, S21+ 5G and S21 Ultra 5G are also one of the targeted smartphone for cloning. You should not be surprised that there are close-enough replica that’s being sold out there. So these are the most obvious and easiest way to spot the differences whether the S21 is a real deal or a fake one.

1) Smartphone Color.

Samsung Galaxy S21 series are only available in these colors (color for the Samsung U.S):

Samsung Galaxy S21 SeriesColor availability
Samsung Galaxy S21 5GPhantom Gray, Phantom Pink, Phantom Violet, Phantom White.
Samsung Galaxy S21+ 5GPhantom Black, Phantom Gold, Phantom Red, Phantom Silver, Phantom Violet.
Samsung Galaxy S21 Ultra 5GPhantom Black, Phantom Brown, Phantom Navy, Phantom Silver, Phantom Titanium.
Samsung Galaxy S21 series color availability for US market

For Non-U.S market, head to to check the official color availability. Any Galaxy S21 colors outside the official color, for sure that’s not the real one.

2) Rear cameras. 

Samsung Galaxy S21 and S21+ have 3 rear cameras, while S21 Ultra has 4 rear cameras. Go to Camera app, cover all the rear camera holes with your fingers, and while you switching between photo mode (zoom, wide, ultra wide and telephoto), uncover the rear camera one by one, ensuring all of the cameras are working and not just dummy. If one of them is not working as expected, then you know that’s not the real one.

3) Rear cameras zoom. 

One of the unique selling point of all Samsung Galaxy S21 series is the capability to do space zoom up to 30x for S21 and S21+ and up to 100x for S21 Ultra. Open the Camera app, zoom the picture to the maximum. If you don’t get up to 30x on S21 and S21+ or if you don’t get up to 100x on S21 Ultra, then you know that’s not the real one.

4) Front-facing camera. 

Now go to the front, do similar thing. Cover the punch hole front camera. Then go to Camera app, switch to front camera, then uncover the camera to see if it is working. If it’s not, then you know that’s not the real one.

5) Single Take camera mode.

All Samsung Galaxy S21 variants have Single Take mode on the Camera app. Single Take mode is a new feature available on Samsung Galaxy S21 series that lets you capture short videos for 5-15 seconds. Now open the Camera app and find Single Take mode. Tap on Single Take and start capturing the short videos. If there’s no Single Take mode nor if Single Take mode doesn’t function as it is, then you know that’s not the real one.

6) Fingerprint sensor. 

All Samsung Galaxy S21 variants use the ultrasonic in-display finger print scanner. So as part of the setup, register with one finger. Once setup is done, locked the phone and turn back on. Now try to unlock the phone but using different fingers (not the one you are registering). If you never register that other fingers but still manage to unlock the device, then you know, it’s not the real one.

7) 120 Hz Display. 

All Samsung Galaxy S21 variants come with 120 Hz refresh rate. Ensure you have the settings. Go to Settings > Display, tap on the Motion Smoothness. The real one should have the “Adaptive” option which basically to adjust your screen refresh rate up to 120Hz. Tap on “Adaptive” to activate it. Then using any Internet Browser on the Samsung Galaxy S21, go to TestUfo (link: to test the refresh rate. Ensure you are getting 120 Hz, otherwise you know that it’s not the real one.

8) Bixby. 

Bixby is the standard voice-assistant that comes with Galaxy S21. Ensure it’s there and working. Press and hold the Side button (Power button) for a few second to activate Bixby. Once activated, ensure it’s Bixby and not Google Assistant – Bixby has ‘B’ logo on it (refer to video below for more details).

9) Wireless Charging.

All Samsung Galaxy S21 variants comes with wireless charging capability. To test the wireless charging, put the S21 to any of wireless charger, if it’s the real one, the phone should start charging.

10) Wireless Powershare. 

On top of Wireless Charging capability, all Samsung Galaxy S21 variants also comes with reverse wireless charging capability – Samsung called it as Wireless Powershare. To test this feature, first you have to enable Wireless PowerShare. Go to Settings > Battery and Device Care > Battery. Scroll down and find “Wireless power sharing”. Turn it ON. Once turned on, using any other items with wireless charging capability (Eg: phone or earbuds), put the other item at the back of Galaxy S21. If it has reverse wireless charging capability, it should start charging your other item (refer to video below for more details).

11) Android version. 

All Samsung Galaxy S21 variants comes pre-packaged with Android 11. So ensure you see Android 11 or above (in case you buy it after it gets updated to latest version of Android). To check the Android version, go to Settings > About Phone > Software Information. If you see Android version as 11 (or above), don’t stop there. Do a few taps on Android version to bring you the real Android version it has. If it’s really Android 11, it should show you the “Android 11 logo”.

I guess that’s it. While there are other things to check (such as 5G and WiFi 6 connectivity, camera quality, etc) but those listed and mentioned above are what I think the most obvious one (and easy one) that both casual non-geek users are able to spot it right away and difficult for the replicator to replicate it – since obviously they don’t have the technology and capability yet to do so (but they are catching up soon).

Things like box, camera quality, AnTutu and Geekbench results are not so obvious one and easy for the replicator to replicate them (Eg: AnTuTu or Geekbench, like I mentioned earlier, they can easily manipulate the results).

In case points above are not enough, have a look at the video from AllSortz below for more review on the S21 Fake and how close it can get to the real one.

Tips to buy and make sure getting the real Samsung Galaxy S21 5G / S21+ 5G / S21 Ultra 5G

If you are buying a brand new one, it’s highly recommended to buy from official trusted store (Eg: Samsung store, telco shops – if you are re-contracting or big-name electronic stores). You shouldn’t have issue or problem.

But what if you are buying brand new or buying second hand on some other markets, shops, or buying online, make sure the phone has those capabilities and features I described above. Also if you are buying online, ask the seller to meet you in person.

Of course if the price is way below the market price, don’t rush to buy before doing all the checking mentioned above.
