Samsung A51:

We have a very lightweight plastic backed device with colors bouncing all over the place when put in the certain light.

On the right side of the phone, we have our power and volume buttons while the left side is buttonless but houses the SIM card tray near the top of the phone which can hold two SIM cards and a micro SD card slot for additional storage.

Type-c port, headphone jack, and the primary speaker are found on the bottom.

Samsung A50s:

You get that GLASSTIC back with the slightly updated triple camera setup placed on the top right corner. I appreciate the little update here in aesthetics as I did find the earlier A50 playing it a little bit too safe. And surprisingly I did notice at the moment I got the device in my hands and I do have a more comfortable grip because of this.

We get the exact same placements as first A50. A noise-cancelling mic for speakerphone up top, a dual SIM card tray with a dedicated micro SD card slot on the left side. Volume rocker and power button on the right and a 3.5 millimeter audio jack USB, type-c port, mic for regular calls, and single downward firing speaker at the bottom.

Samsung A51:

It’s great to see that mid-range phones now having all kinds of lenses to allow you to take all kinds of photos. Even in the a 51 you can see there are four camera lenses.

  • 48 Megapixel (f/2.0, Main Camera)
  • 12 Megapixel (f/2.2 Ultra-Wide)
  • 5 Megapixel (f/2.4 Macro)
  • Depth Sensor
  • 32 Megapixel Selfie Camera (f/2.2)

I have to say, I’m pretty impressed with sapmles. It’s at par with any other smartphone that’s available in this price range and in some cases it’s actually just better than them.

Samsung A50s:

Now let’s talk about the camera’s of A50s. This comes with triple camera setup.

  • 48 Megapixel (f/2.0, Main Camera)
  • 8 Megapixel (f/2.2 Ultra-Wide)
  • 5 Depth Sensor (f/2.2)
  • 32 Megapixel Selfie Camera (f/2.0)

I didn’t expect a great image. We can expect more detail as having a bigger sensor should do so. We get the usual Samsung post-processing though highlights by default tend to overexpose, this can be easily remedied by tapping the focus and lowering the exposure level.

In good lighting conditions, it’s really hard to tell the difference between the quality of the 48 megapixel shooter compared to the 8 megapixel ultra wide. But come low lighting conditions and you can really tell from their. Dynamic range is adequate not the best we’ve seen from a smartphone.

Portrait-wise, subject background separation is pretty good and when I was taking samples I felt like some sharpening was lacking but that wasn’t the case after all.

For video, the A50s can shoot up to 4k at 30 frames per second, you also get Samsung slo-mo and super slo-mo features. Both of which are actually very usable even for only 720p video.

Samsung A51:

One thing that is no surprise here is the trademark Samsung infinity display. It’s a 6.5 inch Super AMOLED with a 1080p resolution and though it isn’t curved it does have some really slim bezels. Instead of a notch for the selfie camera, there’s a punch-hole.

The viewing experience on this screen is great with plenty of sharpness and contrast. Colors can be set accurately in the color settings and brightness is respectable, you can get over 400 nits with a manual slider and around 613 nits in bright conditions with auto mode toggled.

There’s an always on display, which will show you the time and notifications when the phone is asleep and there’s a under-display fingerprint reader to wake up the phone with, it’s reliable but not the fastest around.

Samsung A50s:

The Samsung Galaxy A50s gets a 6.4 inch full HD+, Super AMOLED infinity u panel with a resolution of 2340 by 1080. And a pixel density of 403 pixels per inch. Display protection actually isn’t specified but I think it’s safe to assume that we do get during the glass 3.

If you head over to screen mode in the display settings, you’ll notice that the A50s now has a Vivid profile and gets rid of the other amoled profiles found on the A50.


Samsung A51:

Talking about the speakers of this phone, they are not very good. There is only one bottom firing speaker. For better experience, you should use the 3.5mm audio jack while games or watching movies.

Samsung A50s:

The downward firing speaker produces an average sound signature that kind of lacks in both the highs and lows. It should get you through short viewings but if you plan to just kick it back all day I think it’d be best if users take advantage of the 3.5 millimeter audio jack.

Samsung A51:

Now as for performance, here’s where I felt there was a slight drawback when I was playing games like Asphalt 9 and also PUBG. It was smooth, but I did find the phone becoming quite warm at the top area of the phone. So if you guys are playing games for a long period of time, keep that in mind.

Samsung A50s:

Tthe Galaxy A50s gets an Exynos 9611 chipset coupled with the Mali-G72 MP3 GPU. For configuration, you can get the A50s and either 4 or 6 GB of ram with either 64 or 128 Gb of internal storage.

There is no difference in performance. I played PUBG and I didn’t find any lags or drops. And You can play that game with 60FPS with low settings.

Samsung A51:

There’s rocking OneUI 2.0 based on Android 10 and just like their design Samsung has this a uniform thing with their software as well. So you pretty much get the same kind of software experience as you will see on the flagship phones with some features exclusive to them but overall it’s the same kind of software experience that you will experience on this phone.

One UI 2.0 is one of my favorite Android skins. It comes with very minimal bloatware and feels super-optimized.

Samsung A50s:

On the software front, users will be greeted with Android 9 pie out of the box skin with OneUI on top. This iteration of OneUI basically comes from the Note 10 series, get a power icon on the drop down menu, link to windows features also here, and so much more.

It is practically the same OneUI we’ve all come to love or learn to love. It’s very clean looking as a whole but not without its own notification bugs and such. Though we never ran into any trouble when consuming media, browsing the web, and even like gaming on this.



Samsung A51:

The battery efficiency of these Galaxy A Series devices have been impressive. That’s an important indication when looking at the potential longevity of a handset like this. The battery is sealed and it’s not user replaceable.

This phone comes with 4000 mAh battery and it will survive a full day even with heavy usage. It comes with 15-Watt charger which will charge your phone from 0% to 100% in 1.5 hours.

Samsung A50s:

The A50s supports the 4000 mAh battery with 15-watt fast charging capabilities. I still have 20% in the tank, I still always have to charge this phone before I go to bed though, so that’s why I say it’s average.

In the PC mark battery test, our A50s got a score of 9 hours while in our standard video loop test we got a total of 13 hours of playback.


A50s is cheaper than the A51. In almost every situation, both the phones perfomed almost same. Now which one you should buy? I would say that if you are a camera lover then you should buy A51 and on the other hand, if you just want a good performance then I will recommend A50s.

Personally, I am leaning towards the A50s just because of that performance in less price.
