Samsung Galaxy A12 and Samsung Galaxy A21s:Similarities

Samsung Galaxy A21s has a punch hole selfie camera
Both phones are fitted with a 6.5-inch IPS LCD. That is, same size and same type of panel. The display resolution is the same too: 720 x 1600 pixels. And to cap it, aspect ratio is also the same.
Both smartphones were launched with Android 10, and they are both upgradable to Android 11. Will they get Android 12? That is a discussion for another day.
As far as RAM and internal storage is concerned, once again, Samsung A12 and A21s are evenly matched. And it doesn’t end there: another similarity is in battery capacity and charging technology. Both phones have a 5000mAh battery with 15W fast charging.
At this point, it almost looks like the A12 and A21s are exactly the same device with different branding; right? The list of similarities and shared specs has been quite long. But they do have differences, and we explore those in the next section.
Samsung Galaxy A12 and Samsung Galaxy A21s: Differences

Samsung Galaxy A12
Starting with the visual differences, the A12 has a waterdrop notch on its display, while the A21s has a punch hole in the top left corner. At the back, the camera island layouts are different as well. But the differences are not merely visual and cosmetic; the cameras themselves are different. Galaxy A12 has an 8-megapixel selfie camera, while the A21s has a 13-megapixel selfie camera.
At the back, the rear cameras are both quad shooters and also almost the same, except for the ultrawide camera. The A12 has a 5-megapixel ultrawide snapper, while the A21s has an 8-megapixel ultrawide snapper. All the other specs of the rear camera are similar: a 48-megapixel main shooter, a 2-megapixel macro camera, and another 2-megapixel depth sensor.
Perhaps the most significant difference between Samsung Galaxy A12 and Samsung Galaxy A21s is in the processor department. The A12 has an older and less powerful Helio P35 chipset and PowerVR GE8320 GPU, while the A21s has a more capable EXYNOS 850 chipset and Mali G52 GPU. In layman’s terms, the A21s is the more powerful and more capable of the two devices.
Lastly, is the location of the fingerprint sensor on each device. The A12 has it on the side, while the A21s has it at the back.
Samsung Galaxy A12 and Samsung Galaxy A21s: Conclusions
A comparison between the Samsung Galaxy A12 and Samsung Galaxy A21s is pretty straightforward. They are identical siblings in many ways, but Galaxy A21s is the more capable of the two devices. This is reflected in the prices as well. You pay a little more for the more powerful processor and cameras, if you choose the A21s. Of course, if you are constrained by a budget, the Galaxy A12 is your default option.
The price of Samsung A12 starts from $135 only, while that of the A21s starts from $183. These prices may vary depending on which country you are resident in. Over to you now: we have presented the information you need to make an informed decision. Which is your choice?

The table above has clearly stated the specs of each device and has also gone further to identify which areas one device is better than the other in thick bold letters. So let us go further to state out the similarities and differences between these two smartphones.

Samsung Galaxy A12
Samsung Galaxy A12 and Samsung Galaxy A02s: Similarities
The first and most obvious similarity between these two devices is the fact that they are produced by the same company and are also for the same line-up (Awesome series). Moving forward to the more important things that these devices share in common, we have the screen size to talk about. They both have 6.5-inch PLS IPS displays with a 20:9 aspect ratio, and the same amount of pixels.
Battery life and charging speed also stand out as features these two mid-rangers share in common. The same 5000mAh battery is present in the two devices with a 15W fast charging brick packed in their individual retail boxes.
Also, both devices support a major Android update for 1 year. They both run Android 10 out of the box, but they can both be upgraded to Android 11. Asides the already stated similarities, there are no other similarities to point out.

Samsung Galaxy A02s
Samsung Galaxy A12 and Samsung Galaxy A02s: Differences
First, I want to talk about storage. The Galaxy A12 has more storage options, unlike the Galaxy A02s, which gives 64 GB as it’s maximum storage limit for its ROM capacity. The Galaxy A12 peaks its storage limit at 128 GB on the ROM. When it comes to the RAM capacity on the two phones, they both peak at 4 GB of RAM, but with the A12 you are getting a slightly faster storage.
Now to the processor. The MediaTek Helio P35 chipset on the Galaxy A12 makes it a better option to the Galaxy A02s’ Snapdragon 450. As far as raw power is concerned, the Galaxy A12 is the right pick for you.
Glancing your eyes at the camera abilities of these two devices, you will see that the Galaxy A12offers better spec’d camera than the A02s. The Galaxy A12 has a quad camera setup which houses a main 48MP shooter and even a 5MP ultrawide camera, while the Galaxy A02s has a less powerful 13MP main camera with rather weak complimentary cameras and no ultrawide camera. For the selfie shoots on the both devices, the Galaxy A12 is the clear winner with its 8MP shooter.
Another very noticeable difference is the fact that the Galaxy A02s does not have a fingerprint sensor, while you have a side mounted fingerprint sensor on the Galaxy A12. So if you want a smartphone that you can unlock with biometric data, consider getting the A12 instead of the A02s.
Samsung Galaxy A12 and Samsung Galaxy A02s: Conclusion
Our two contenders in the ring today, Samsung Galaxy A12 and Samsung Galaxy A02s, start off at different prices. The Galaxy A02s goes at a retail price of $110, but paying an extra $25 will get you the Galaxy A12 with even better features at just $135.
