review with features, price and specifications

22 mayo, 2021

The Galaxy S family is Samsung’s main workhorse at the beginning of the year. Despite following the tradition the South Korean company has changed its declaration of intent, launching in 2020 three proposals for this family: Samsung Galaxy S20, S20 + and S20 Ultra. Although the Samsung Galaxy S20 Ultra has captured a good part of the attention, its younger brothers are still interesting.

After several days of use with the Samsung Galaxy S20, it is necessary to tell what we have found with the device after passing it through our analysis table. It is one of the few compact proposals of the high range, with a clear objective of trying to win in its segment. We are going to review both its specifications and features as well as detail the experience we have had with Samsung’s “small” flagship.

Design: compaction as a key factor


The Samsung Galaxy S20 has several differentiating points in its design, so let’s start by reeling off its back. The first thing that strikes us is rear module, platform that houses the triple camera of the device. Although it is not as massive as in the case of the Ultra model, it occupies a good part of the first upper third of the device, in addition to protruding from the body of the terminal in a remarkable way. If we use the mobile without a cover, it is easy for it to “dance” on any surface since the module is the first point of support for the phone. This size also implies dust accumulation quite simply, nothing dramatic, but point to keep in mind.

The main problem with the Samsung Galaxy S20 at the design level is how slippery it is. Apart from fingerprints, it also attracts a lot the little fat that the fingers may contain

The rear glass is not matte, which means that footprints are quite easily marked, something common in this type of finish, although somewhat exaggerated in the case of this Samsung Galaxy S20. What is not so common is how slippery the device is. Unless we hold it quite firmly, the terminal will “try” to escape from our hands, something that makes it more prone to falls. In this case, unlike the Ultra model, a cover is not included so we recommend using the device with one to improve grip and eliminate the problem of fingerprints.


Despite being a slippery device the Samsung Galaxy S20 is enjoyed and a lot in hand. It is one of the most compact bets on the market, growing just 1.2mm compared to the Samsung Galaxy S10. Also helping here is its weight of just 163 grams, quite a rest for the hand in a high-end range that is starting to establish over 200 grams as a standard.

Height (millimeters) Width (mm) Thickness (millimeters) Weight (grams) Screen (inch) Drums Surface (cm2) Volume (cc)
Samsung Galaxy S10 149.9 70.4 7.8 157 6.1 3,400 105.52 82.31
Samsung Galaxy S20 151.1 69.1 7.9 163 6.2 4,000 104.41 82.48
Samsung Galaxy S10 + 157.6 74.1 7.8 175 6.4 4,100 116.78 91,089
Samsung Galaxy S20 + 161.9 73.7 7.8 186 6.9 4,000 104.41 82.48
Samsung Galaxy S10 5G 163.3 77.1 7.9 198 6.7 4,500 125.06 98.79

Img 7566 It is not a particularly thin terminal, but the thickness is in line with what we usually find in the high range.

As we can see, the differences in size and weight compared to the rest of the members of the Galaxy family are notable, this being the least wide of all and achieving a good balance at the surface and volume level, even more so considering that it houses a 4,000mAh battery. Once we have seen how it looks in front of its own family, we will make the comparison with terminals with a similar screen diagonal.

Height (millimeters) Width (mm) Thickness (millimeters) Weight (grams) Screen (inch) Drums Surface (cm2) Volume (cc)
Samsung Galaxy S20 151.1 69.1 7.9 163 6.2 4,000 104.41 82.48
Huawei P40 148.9 71.1 8.5 175 6.7 3,800 105.86 89.98
Google Pixel 4 147.05 68.8 8.2 162 5.7 2,800 101.17 82.95
Sony Xperia 5 158 68 8.2 164 6.1 3,140 107.44 88.10
LG G8S THINQ 155.3 76.6 8.1 180 6.21 3,550 118.96 96.24
iPhone 11 Pro 144 71.4 8.1 188 5.8 3,179 102.81 83.28

Compared to other terminals with a similar screen diagonal the Samsung Galaxy S20 manages to place itself on the podium of compact mobiles. With a 4,000mAh battery and a 6.2-inch panel, it has less volume than a Huawei P40, a model with less screen, height and battery. The translation of this is that, despite being a terminal of more than 6.2 inches, it is compact, comfortable and easy to use with one hand, with the only handicap of being slippery as we discussed earlier.

Having dealt with the dimensions, it is interesting to address the design lines of this Samsung Galaxy S20 since there have been changes compared to the previous generation. Samsung has decided not to make the sides of the panel so curved (which we will talk about later) something that, in the opinion of the server, is a success. The terminal does not lose its soul “Edge”, so little useful on a practical level but so striking on a visual level for many users. It is still a terminal that stands out for being curved and continues to work well visually, without being as exaggerated as in previous generations.

The build quality of the Samsung Galaxy S20 is excellent. Metal frames, glass and a design line in which curves are the protagonists in front and behind

The terminal is not symmetrical seen from the front since although the frame reduction exercise is excellent, there is still a small lower chin wider than the side and front frames. The only drawback of the front is that the junction between the edge of the device and the screen leaves a tiny gap through which dirt can enter.

The frame that surrounds the terminal is metallic and houses the volume and power buttons on its right side, with the SIM card slot on the top of the terminal. The base of the terminal houses the main speaker and the USB Type C that is not aligned in this case in the center, as in the case of the Ultra, but slightly displaced towards the bottom.

Img 7569 The top speaker is difficult to perceive. It is located between the frame and the screen, very discreet.

The location of the front speaker is striking, located between the top frame and the screen. It is so discreet that it is difficult to see it with the naked eye. In the same way, we have a small hole in the screen to avoid the notch, something that allows the Samsung Galaxy S20, according to GSMarena data, to achieve a frontal utilization of 89.5%. The hole, in our opinion, is quite aesthetic and we forget about it after a few minutes of use. Later we will talk about how it affects the content, but we already tell you that it will not pose any problem.

In short, the Samsung Galaxy S20 is a nice terminal, well built and very comfortable in hand. Its main drawback is how slippery it is in the hand, something that can be easily solved with a cover.

Display: sir, have you heard of 120 Hz?

Img 7548 6.1 inches, great front end and 120 Hz. Well, this looks great.

Once they knock on your door to tell you about the benefits of 120 Hz and you have the opportunity to try them, going back becomes very complicated. Samsung once again opts for a panel with WQHD + resolution with Super AMOLED technology, support for HDR 10 and 6.2 inches in the case of this S20. However, the main strength is 120 hertz, one of the highest refresh rates on the market.

Betting on 120 Hz implies giving up the QHD + resolution. Resolutions below 2K do support this high refresh rate

Using 120 hertz, however, has a small tribute associated with it: the resolution. The default terminal is configured in Full HD + and 60 Hz, being able to configure it to go down to HD + or to go up to Quad HD +. If we go up to 2K we lose the possibility of 120 hertz.

OLED, AMOLED, Super AMOLED and Dynamic AMOLED: how Samsung's screens differ

Samsung Galaxy S20

The jump to this refresh rate is more than remarkable. It is quite noticeable at the scroll level and allows the transitions and animations of the system to move more fluidly (twice the FPS, neither more nor less). In our opinion it may be worth sacrificing resolution for the refresh rate as the user experience changes completely.

Img 7540 The problem with the curves of the Galaxy S20 is the difference between the content in flat and the rest in the curve. It is easy to see reflections and shadows.

Beyond the refresh rate in general terms we are facing an outstanding screen with good levels of brightness, more than enough contrast, very sharp (especially in QHD +) and with a very high pixel density. Play in your favor compared to last year the low curvature that has been chosen in this generation. There is still a small shading in this area, visible to the naked eye, but it does not cloud the user experience. The viewing angles are correct, with slight color variations quite common in AMOLED panels.
