As seen from the specifications of the two devices, there are a few similarities and lots of differences, which we will talk about. Noteworthy is the fact that Samsung proved that the age of a device does not actually determine how it will perform when placed alongside other devices. Like we stated earlier, these devices are clearly a year apart, yet the older device stands head and shoulder above the newer.

As we saw from the table above, the older Samsung Galaxy A51 came up as being the better one, with its specifications clearly higher than the more recent Galaxy A12. Of course, that is understandable, considering that it occupies a higher rung on Samsung’s catalogue. Let us look at a few things that these two smartphones share in common.

First and foremost is the fact that they are both upgradable to Android 11, this is a very important feature that I personally consider before getting a new device and this is because of the sustainability of devices. This feature is mainly common in flagship Android devices, since manufacturers understand that customers are paying much, and so might need the device to last longer than usual. It is good to see this feature on midrange devices from Samsung.



The second shared feature is that the two devices share the same charging speed, 15W fast charge. You might not consider 15W as fast charge, but that is actually a valid way to go – not too fast and also not too slow..

Now, this is where the big guns come to play, and these two devices start throwing punches at one another. There are a lot of differences between them.


The first and most noticeable difference is in the screens. The A51 packs a crisp and bright Super AMOLED display, while it distant relative, the A12, has a less attractive PLS IPS display. Do not get me wrong: the screen on the A12 is good, but definitely nowhere as good as what is on the A51. The A51 also has a 1080 × 2400 pixels resolution as against the 720 ×1600 pixels resolution on the A12. Conclusion: with the A51, you are getting more pixels, hence a brighter screen with more viewing angles.

Another very noticeable difference between these two devices is the processor, the A12 comes with a less powerful MediaTek Helio P35 as against the EXYNOS 9611 chip on the A51. The Galaxy A51 is faster than the A12 and also better for gaming (if you are the type that plays games).


When it comes to photography, bot smartphones have similar main cameras at 48MP, but the game turns in the favour of the A51 since it has better complimentary cameras and also a better chipset to process the images taken and with the selfie camera the A51 packs an even high camera with 32MP as against the 8MP on the A12.

With storage, the A51 gives you a wider option as it packs higher storage variants than the A12. Fingerprint sensors are also positioned differently, as the A51 houses an under display fingerprint sensor thanks to the Super AMOLED screen while the A12 has a side mounted fingerprint sensor.

Well all the blows have been in favour of the A51 but the A12 saved the last and yet one of the best blows for itself and that blow is the battery, the A12 packs a better 5000mah battery as against the 4000mAh battery on the A51. It is just like a losing boxer who delivers a heavy punch at the end of the match so that no one will say he went down without a fight.

Samsung Galaxy A12 vs Samsung Galaxy A51: Conclusions

Well this has been a big contest between the Samsung Galaxy A12 and the Samsung Galaxy A51, so if you are deciding to get any of these devices it is important to keep this article in mind also note that the pricing of these devices is wide, so you will be paying $153 above the price of the A12 ($135) to get the older A51 at $288. Also, since the A12 is a more recent device, it will get more security patches and Android updates than the A51. So the decision all comes down to what you want.
