Samsung Galaxy A21s Review: Amazing Look

Samsung Galaxy A21s Review: Samsung launches tons of smartphones per annum, but in doing so, they are doing to bring some overpriced and underpowering phones. The Galaxy M11 we reviewed a short time ago was one such example, and since then I even have been using the Galaxy A21s alongside my favourite budget phone at the instant, the Galaxy M21. The A21s is slightly costlier than the M21 for an equivalent memory configuration, so which one do you have to pick? Let’s determine during this review of the Samsung Galaxy A21s Review.

Samsung Galaxy A21s Review:


  • A stunning and mesmerizing reflective rear panel
  • Slightly hefty and an all-plastic build

So, the primary thing to love about the Galaxy A21s is its design.

Take a glance at this thing, absolutely stunning. This glossy and reflective real panel could mesmerize you for days, I do know it did on behalf of me so. because of its curved body, the phone has a superb grip also with a touch little bit of heft too, though I would’ve preferred something lighter. Surprisingly, the A21s is slightly heavier than the Galaxy M21 which comes with a 20% larger battery. Samsung Galaxy A21s Review

As expected, Samsung has gone with an all-out plastic build and therefore the glossy finish definitely aids in some smudges and fingerprints sticking to the phone. Yet, I’m happy to report that it’s not what you call a “fingerprint magnet”. Therefore, you’ll retain the gorgeous search for long without breaking any sweat.

Ergonomic button placement

Both the facility & volume rockers reside on the proper while a SIM tray sits on the left side of the phone. The buttons click just fine and are positioned tolerably to be at reach. the highest portion of A21s remains mostly barren apart from the microphone, while a 3.5mm headphone jack, a Type-C data/charging port, and a speaker grille are often found at rock bottom.

Once again going to the rear of the phone, it borrows the L-shaped camera module from other phones just like the Galaxy M31 with a small but inconsiderable bump. Adjacent to the cameras may be a traditional fingerprint sensor we’ve typically seen in many budget-oriented and mid-range Samsung smartphones. Anyway, A21s has an impressive design for a reasonable phone albeit the corporate could’ve worked the load a touch. Therefore, this is often one among the sole two things that I am keen on this phone. Samsung Galaxy A21s Review


  • 6.5-inches PLS TFT LCD panel with HD+ resolution
  • Mediocre sharpness & colour reproduction, plus screen flickering issue

Moving on, the display is typically where Samsung phones shine the brightest but sadly it’s not the case here. It’s just bad, so bad. Even the trendier punch-hole cutout for the front-facing camera isn’t ready to save grace for the phone’s display quality. I mean, have a peek for yourself. This undersaturated panel features a terrible colour reproduction and you’ll instantly recognize the mediocrity.

Samsung Galaxy A21s Price, Samsung Galaxy A21s, Samsung Galaxy A21s Performance, Samsung Galaxy A21s Review, Samsung Galaxy A21s Camera, Samsung Galaxy A21s Design, Samsung Galaxy A21s battery, Samsung Galaxy A21s Gaming

Getting to the nitty-gritty details, the Galaxy A21s features a 6.5” Infinity-O PLS TFT LCD panel with an HD+ resolution and a 20:9 ratio. So yeah, the viewing experience on this phone wasn’t great in the least. The sharpness isn’t quite there and I’ve already talked about the inferior colours.

Punch-hole cutout can’t save the averageness

The punch hole on the left corner does increase the modern-ness of the phone and everyone, but it’s still a victim to mild screen bleed around the outline of the cutout. Brightness is okay for indoors although the A21s will cause you to add terms of visibility when you’re directly under the sun.

Adding further insult to the injury is how the display flickers. What?! That, in no way, should be happening on a 2020 phone. When sliding down the brightness of the phone to the minimum or turning on the “Medium Power Saving” mode, I could clearly notice how the Samsung Galaxy A21s fails to close-in on the set level of brightness during my review. this is often most noticeable when you’ve turned off dark mode and are using light-themed applications like Facebook, or simply browsing through the settings. Samsung Galaxy A21s Review

Talking about the dark mode, I need to admit it’s well implemented albeit it lacks the Always-on Display feature found on AMOLED-boasting Samsung mid-rangers just like the Galaxy M21. beat all, A21s features a less-than-average display with forgettable colours, average sharpness, and a frightening screen-flicker issue. the quality Galaxy A20 of last year had a shocking AMOLED panel and that I cannot fathom why the corporate goes with a menial one on its successors.


  • Quad-cameras at the back
  • (48MP primary, 8MP ultrawide, 2MP macro, 2MP depth sensor)
  • 13MP front-facing camera inside a punch-hole cutout

Camera-wise, the Galaxy A21s features a quad-lens system at the rear with a 48MP primary sensor, an 8MP ultrawide lens, a 2MP macro lens, and a 2MP depth sensor.

Macro Images

As usual, the 2MP macro lens is just about useless as shots begin barren of any detail.

And you’ll get to put during a lot of labour for just a mediocre shot.

Normal Images

The other three lenses are literally excellent. But comparing the first 48MP sensor with the M21, it’s almost identical apart from the minute difference in colour tone.

Both these phones are capable of capturing good daylight images, with good colours, contrast, and dynamic range. Likewise, they’re also on par when it involves details and sharpness.

Wideangle Images

Wide-angle photos share an identical story. That is, it’s just like that of the M21 images. In day times, you’ll get good colours, sufficient dynamic range, and wide field of view.

Overall, the A21s wide-angle images are better than your typical budget phones like Realme 6i or the Redmi Note 9.

Portrait Images

In terms of portraits too, its good for the worth with good subject focus, decent bokeh, and background colours.

It is almost just like that of the M21’s portrait as you’ll see during this image here.

Selfie Images

Selfie-wise, you get a 13MP sensor whose images look almost nearly as good because of the selfies from the 20MP sensor of the Galaxy M21. there’s just a small difference in complexion, otherwise, images from both the devices look almost identical.

The portrait selfies share an equivalent fate where both have good colours but average edge detection.

Nighttime Images

Nighttime images on the A21s wildly vary between the traditional and wide-angle mode, with the latter leading to much warmer shots. Details aren’t quite there either. and therefore the most disappointing part is, you don’t get night mode here.

Finally, videos are maxed bent FHD resolution at 30fps on both front and rear cameras of Galaxy A21s; both of which lack any kind of stabilization. Recordings from the rear camera are ok for normal users because it has good colour reproduction and a touch wide field of view. On the contrary, selfie videos are riddled with overexposure and a terrible dynamic range.

But, overall, I’ve liked the cameras of the A21s, It’s almost just like that of M21, and is best than say its competitors just like the Redmi Note 9 or the Realme 6i.

Performance & Memory

  • Octa-core Exynos 850 SoC (8nm)
  • Either 3, 4, or 6GB of RAM with up to 64GB of internal storage

The performance on this phone isn’t one for the books either. Well, Samsung has been consistently notorious regarding indecent chipset selection but this one takes the cake for the foremost out-of-place SoC placed on a midrange phone. And yeah, it’s a homegrown Exynos silicon from the corporate. To be fair, it’s manufactured under a way efficient 8nm process node and thus is extremely energy-friendly.

Samsung Galaxy A21s Price, Samsung Galaxy A21s, Samsung Galaxy A21s Performance, Samsung Galaxy A21s Review, Samsung Galaxy A21s Camera, Samsung Galaxy A21s Design, Samsung Galaxy A21s battery, Samsung Galaxy A21s Gaming

This new Exynos 850 has octa-core Cortex-A55 CPU, all clocked at 2.0GHz. We’re already conversant in this Arm design and know that it’s a power-efficient CPU. due to this, the performance of A21s is below a suitable level. In terms of memory, you’ll choose from 3, 4, or 6GB of RAM with up to 64GB of internal storage counting on the market. It runs on OneUI Core rather than the quality OneUI and thus is barren of certain features sort of a dedicated night mode on the camera, Secure Folder, etc.

But it didn’t really bother me because the core experience was just about what I’ve come to seem for from OneUI. My review unit features a 4/64GB configuration and my experience with the phone was as abysmal as you’ll imagine. I’m sure memory management could get a touch better in higher RAM variants but I can guarantee that paying for more memory won’t end in a faster, swifter workflow on the A21s.

Lightweight apps work fine though

Yet, the Exynos 850 can handle lightweight apps and multitasking between them pretty much. But if they’re joined by another heavy apps or games, then the equation becomes entirely different. Memory management isn’t great (a reminder once more that the unit I’m using has 4GB RAM) and therefore the phone misbehaves when it goes to within the hay|love|make out|make love|get laid|have sex|know|do it|be intimate|have intercourse|have it away|have it off|screw|fuck|jazz|eff|hump|lie with|bed|have a go at it|bang|get it on|bonk|copulate|mate|pair|couple”> roll in the hay RAM-intensive applications still in the memory and you are trying to wake it up.


Likewise, don’t expect any outlandishly extravagant gaming experience on the A21s either. Popular titles like PUBG Mobile, PUBG Lite, and Call of Duty: Mobile is playable but there’s a catch with each of them. PUBGm was almost entirely unplayable with noticeable lag & stutter under “Smooth” graphics and “Low” frame rate, even under “Deathmatch” mode.


So, I attempted out its lite version instead which ran comparatively well under “Smooth” graphics and “Medium” frame rate. Shockingly, I witnessed smooth gameplay in CoD under “Medium” graphics and “High” frame rate. Besides these, other undemanding games like Injustice 2, Mobile Legends are well within the playable boundary too.


  • 5000mAh battery with 15W fast charging
  • Easily a two-day phone with light to medium usage

Do you remember how I said that the planning of the Galaxy A21s is one among the sole two things I prefer about the phone? Well, the opposite thing is the battery. it’s an enormous 5000mAh cell albeit some “M” series phones from Samsung accompany a bigger 6000mAh battery. Nevertheless, I can honestly say it’s a far better endurance than those phones which is especially because of the subsequent factors:


The phone easily lasted me two days which consisted of hours of web browsing, YouTube binging, and a touch little bit of gaming now then. What’s more impressive is how the phone is susceptible to excessive heating even after a protracted session of gaming. So, good job on the battery front, Samsung! Still, charging it’s a pain as I clocked in 2 hours and 26 minutes to completely charge the phone from nil to full.

In the middle of praising the phone for its excellent battery, I need to share a rather unfortunate incident. My review unit of the A21s suddenly visited the boot menu and got stuck there once when it had been running low on battery. I commit it to memory had about 14% charge left and even as I used to be close to plug-in the cable, all I could see was the Samsung logo on the startup screen. Thus, I had to force restart the device by long-pressing the facility and volume-down button directly. However, this didn’t reoccur next time the phone was running low on battery. Samsung Galaxy A21s Review


What else? Yes, let’s discuss the fingerprint sensor. The registration process was a touch weird, to start with. Usually, a phone would prompt you to scan the front of the finger, then its edges separately to urge an honest read of the whole finger. But on this phone, all you would like to try to do is scan the finger within the same position (if you are feeling like it) and that’s about it. Samsung Galaxy A21s Review

As a result, the phone would only recognize my fingerprint, like 3 out of 5 times. A21s also features face-unlock which isn’t the fastest and only works with sufficient ambient light around you. Samsung Galaxy A21s Review

The audio output from the only bottom-firing speaker is okay, but only at low to medium volume. Cranking up the loudness will end in lossy and distorted audio. It supports Dolby Atmos too but that only works on wired earphones or Bluetooth headsets. Here, the wired output is considerably better than the speakers. Samsung Galaxy A21s Review

Samsung Galaxy A21s Review: Pros & Cons


  • Excellent design with a fashionable reflective rear panel
  • Great battery endurance (a proper two-day phone)
  • Decent camera performance


  • Terrible value for money
  • Forgettable display with unsaturated colours & minimal sharpness
  • Exynos 850 is power-efficient but not that powerful


In conclusion, the Samsung Galaxy A21s is an honestly worse-than-average smartphone for the worth as I discovered during my review. Featuring an HD+ TFT panel, a processor with only power-efficient CPU cores, etc. speak volumes. the sole things in its favour are the planning, and battery endurance. Samsung Galaxy A21s Review

But ultimately, these are like putting lipstick on a pig. The end-user experience is simply not well worth the price and that we strongly recommend you choose the Galaxy M21 instead, which has an AMOLED display, powerful Exynos 9611 SoC, and better cameras at a more or less an equivalent price.
