Will you accompany us to see them?

Samsung Galaxy A21s vs Samsung Galaxy A30s

Samsung's best sellers, finally face to face ... Which one will be worth more?

In this case we are talking about the Samsung Galaxy A21s and its more performance cousin the Galaxy A30s, two smartphones that maintain the best credentials of Samsung experience but they lower their prices greatly, the first around 150 euros and the second below 250 euros with a datasheet a little more attractive.

It is not easy to choose in these cases, the truth, because differences in the cheapest cut are usually not too obviousAlthough this time it certainly seems that the slightly higher investment of the Galaxy S30s is worth it. In any case, we will not stay in this initial assessment, because what we want is give you a cable when choosing the most suitable mobile for you.

What if we like Samsung and we don't want to spend too much money? Well, here we analyze two good options such as the Galaxy A21s and Galaxy A30s, so that we can all decide which one to buy with all the necessary information.

Design and build: two different concepts with Samsung DNA

The first thing that should be noted here in both terminals is that, certainly, it is one device from 2019 versus another from 2020, so the aesthetic touches are expected. In fact, the Galaxy A21s shows an all-screen hole design for the front camera, while the Galaxy A30s is content to keep the notch in the form of a drop of water without being too disturbing either.

For the rest, we will not find palpable differences in two smartphones built in plastic materials, with a front in tempered glass without noble signature although with a much less optimized size and weight in the most economical model, as you will now see.

In fact, the Galaxy A21s measures 163.7 x 75.3 x 8.9 millimeters and weighs 192 grams, with a 6.5-inch panel, while the Galaxy A30s enjoy a 6.4-inch screen in a size of 158.5 x 74.7 x 7.8 mm, stopping the scale at the 169 grams.

The rest of the differences in design and construction are in its main photographic module, with more cameras on the Galaxy A21s although showing similar utility and versatility, and with a traditional fingerprint reader on its back instead of the Integrated optics under the panel that mounts the Galaxy A30s in a much more comfortable position.

Both have Type-C USB, both also have a 3.5 mm audio jack connector that makes it possible to enjoy FM Radio with headphones as antenna, and both they arrive in several striking colors so that the youngest of the place can choose at ease.

The screen tips the balance, IPS vs Super AMOLED

Well yes, in this case the truth is that here is the section that changes everything, and we all know that the screen focuses practically the entire user experience on a smartphone, so having a panel with Super AMOLED technology instead of an IPS it's key for the Galaxy A30s.

We are not going to discover the benefits of one technology or another, we have already done it a thousand times, but there is no color - never better said - between the much more attractive experience of seeing an AMOLED compared to an IPS, without also counting on the energy saving inherent in OLED technology.

In this case, however, the PLS IPS panel of the Galaxy A21s, with 6.5 inches and HD + resolution (1,600 x 720 pixels) in 20: 9 format, although it has almost exactly the same screen density as the 6.4-inch Super AMOLED and HD + resolution (1,560 x 720 pixels) in 19.5; 9 format of the Galaxy A30s, both hovering around the 270 pixels per inch.

It won't clash with the Galaxy A21s, which saves quite a bit of money, but We must not forget that Super AMOLED technology is better and offers higher quality clearly. Furthermore, it even allows the Galaxy A30s take better advantage of its front with 84.9% screen ratio to total size (82.8% on the Galaxy A21s).

Samsung signs the hardware platform with a note of sufficient for these two Galaxy

In the hardware section I have mixed feelings, and that is on the one hand the Galaxy A21s offers a Samsung Exynos 850 chipset with manufacturing technology 8 nanometers, ensuring better energy optimization, although it is certainly a less powerful chipset the 14 nanometer Exynos 7904 that mounts the Galaxy A30s.

The two however will play according to what is expected of a basic cut smartphone, so there will be no power problems in any, leaving the differences in two clear sections that now we reel off.

On the one hand the graphic part, much more performance in the most expensive model, since the Galaxy A30s offers an ARM Mali-G71 MP2 GPU leaving for the Galaxy A21s a Mali-G52 of a noticeably inferior conception.

We compare the Samsung Galaxy A21s and Samsung Galaxy A31: which of the two is better?

Nevertheless, those who seek greater autonomy, award for the Galaxy A21s, since its 8 nanometer chipset will offer better energy optimization and also this model has a 5,000 mAh battery, huge, also with respect to the 4,000 mAh of the Galaxy A30s. At least, consolation for the A30s, they both have fast charge up to 15W no wireless bragging.

In terms of memory, enough for both of us too, with options that start from 3 GB of RAM and 32 GB of storage, always expandable via microSD cards. In the Galaxy A30s model, for Spain, its configurations start from 4 GB of RAM and 64 GB of storage, so a little more for it.

Connectivity is identical too, with full compatibility up to 4G LTE and active dual SIM, Dual band Wi-Fi, Bluetooth 5.0 LE, aGPS with GLONASS, GALILEO and BDS, NFC and radio FM radio, in addition to the aforementioned audio jack and USB-C connectors.

Quite a few differences in mobile photography, with quality over quantity

Regarding mobile photography, the conceptions here are very different, perhaps marked by the age of both devices, prioritizing quantity over quality in the most modern, which is also the cheapest.

In fact, the Galaxy A21s has up to 4 sensors, although two will be very little usable with 2 MP for macro and depth, leaving to the Galaxy A30s with "only" three cameras, the angular, the ultra wide angle and the depth to improve focus.

Here you have your technical possibilities in a table, because this is much better understood face to face:

48 MP wide (f / 2.0), PDAF25 MP wide (f / 1.7), PDAF
8 MP ultrawide (f / 2.2), 123º8 MP ultrawide (f / 2.2), 13mm-equivalent

While the results will not be too different, it seems clear that the Galaxy A30s bet on fewer sensors and better quality, especially its main 25 megapixel with aperture f / 1.7. In the case of the Galaxy A21s, it is about offering the maximum versatility with only acceptable results without much fanfare.

On the front we find a 13 megapixel sensor in the Galaxy A21s, for a 16 MP sensor in the Galaxy A30s, and both models have ability to record video up to FHD 1080p resolution at 30 frames per second with both the front and rear modules.

Samsung Galaxy A21s vs Samsung Galaxy A30s, which one do I buy?

As you have already seen, it is about two quite similar smartphones in terms of target audience, with a level of benefits and approximately 100 euros difference so that we can choose from all perspectives.

If your budget is very tight, The Galaxy A21s will not disappoint you in any case, although if you can spend that extra, the truth is that the Galaxy A30s jumps a little bit in power, better screen, more memory and average cameras but with a touch of quality more due to the superiority of its sensors.

In any case, the differences are minimal and that should not mislead us, because we are facing two incoming smartphones that, first, must enter through the eyes. So that, If you like the hole in the screen, you only have the Galaxy A21s on the horizon, what about if He notch It is not a problem for you, you can opt for the Galaxy A30s.

There is another key difference that could tip the balance, and that is autonomy, which in your case is clearly in favor of the Galaxy A21s with much more capacity, 5,000 mAh, and the same fast charge of 15W.

Otherwise, the choice remains your responsibility as always, although now with all the information of both models to be able to compare them accordingly inside a Samsung catalog full of attractive options with your One UI experience and Android 10 in both cases.
