Compare Samsung Galaxy A51 VS Samsung Galaxy A50s VS Samsung Galaxy A50


Samsung being the market leader in smartphones for many years now, it is logical to think that among its catalog, however wide, there are best selling models in each season. In the present generation, that honor has touched the Samsung Galaxy A50, one of the most balanced models in terms of performance and price of its refundable series A. But now it has been their turn to renew.



It has already undergone an intermediate renovation. To this Samsung Galaxy A51 which debuts on Thursday was followed by a Samsung Galaxy A50s mid season. It is time, therefore, to check what has changed in the year that has elapsed between the Samsung Galaxy A50 and the Galaxy A51. What does Samsung give us at the change of season so that we opt for the new copy of its midline?

Similar powers, but we grow in RAM and screen diagonal

Land the Samsung Galaxy A51, we lift the hood to see what changes its manufacturer has made in the engine and we run into the same brain that has accompanied the inaugural model and also the renewal mid-season. The Exynos 9611 seems to remain at the forefront of controls with its eight cores at 2.3 GHz and 1.7 GHz, although memory has undergone an evolution.

The Galaxy A50 arrived with 4 GB and in the Galaxy A50s we had the option of keeping them in the same figure or growing up to 6 GB, now in the Samsung Galaxy A51, there is no possibility of going back. Galaxy A51 comes with three RAM options (4 GB or 6 GB or 8 GB) Globally along with 64 GB or 128 GB storage. And of course, the microSD tray is maintained.

As for the screen, there have also been changes. Mainly because Samsung changes the way the front camera is placed and we no longer have a top-notch but a perforation on the screen. This allows the manufacturer to further stretch the diagonal and also increase the ratio. We no longer speak of 6.4 inches 19.5: 9 as in the previous models but of 6.5 inches 20: 9. FullHD +, that does not change, only now it is 2,400 x 1,080 pixels, nor does it change to have a fingerprint reader under the panel.

As a curiosity, the model has not changed much in terms of dimensions and weight this year. We now have 7.9 millimeters thick instead of the original 7.7 millimeters and the phone now weighs 172 grams instead of 166 grams (it went to 169 grams in the A50s). All this without changing the battery, which remains at 4,000 mAh and respects the fast charging of 15W that it has had in the last generation.

The cameras grow in number and resolution, although not all

The photographic section already changed when the Samsung Galaxy A50 jump to the Galaxy A50s. The triple system was maintained but now we no longer found 25 megapixels in the main sensor but a 48 megapixel brand of the house, with an ISOCELL. But both the secondary lens, the super wide angle and the one in charge of depth readings kept the resolution at 8 and 5 megapixels.

Now, the Samsung Galaxy A51 introduces the fourth camera and varies some resolution. The main camera remains at 48 megapixels, the super wide-angle rises to 12 megapixels and we still have 5 megapixels for depth readings. The fourth camera, with a macro lens, is 5 megapixels and makes the Galaxy A51 even more versatile in photographic matters.

As for the front camera, the only change occurs in the lens because it is now a bit darker. If in the Galaxy A50s we already find 32 megapixels with f / 2.0 lens now we have them with an f / 2.2 lens, but it does not change the utility of it or the software functions.

For the rest, we still have Samsung ornaments for this midline. The presence of Samsung Pay is maintained alongside the NFC chip, the ability to use two SIM cards is maintained and Bixby does not stop accompanying us during the trip, hidden behind a One UI that runs on Android 9.0 Pie. We assume that the update to Android 10 and One UI 2.0 will not do much to beg.
