Design Samsung Galaxy M31

Continuity in a design that is falling behind

The Samsung Galaxy M31 will not be remembered as the smartphone with the best design and finishes in the South Korean firm’s catalog.

In this smartphone we will not find a cast of premium materials or science fiction designs. Samsung has preferred to invest a little less abroad to give the rest inside.

At first glance at the Galaxy M31 , we found few aesthetic differences in terms of overall design as both share the smooth, rounded lines outlined against a polycarbonate back that forms the unibody of the Samsung Galaxy M31 . The Galaxy M31 we’re reviewing sports the shiny metallic blue finish, but it’s also available in black and red finishes. Samsung Galaxy S23 price Bangladesh. The curve is a constant in the design of this Samsung mobile, which fits perfectly in the palm of the hand.

It is a smartphone with a size of 159.2 x 75.1 cm and 8.9 mm thick . Quite an achievement considering that it is a mobile that is very well equipped in terms of battery and that it remains at 191 grams of weight .

The most prominent element on the back is the camera module located in the upper left corner. This module follows the square distribution trend that Samsung has adopted in its 2020 models, with a very contained thickness that barely protrudes from the back.

Centered in the upper third is the fingerprint sensor . As was the case in the Samsung Galaxy M30s, the fingerprint sensor remains too long and does not provide easy activation.

In addition, its shallow depth means that it is not easy to find it by touch . This, together with the ease of catching fingerprints on its glossy finish, will make it difficult to keep the back of the smartphone clean.

The edges of the Samsung Galaxy M31 present a very clean profile in which all the buttons are grouped on the right edge. As was the case with the fingerprint sensor, the position of these buttons is somewhat high and they are not entirely comfortable.

The power button does allow correct activation, but this is not the case with the volume buttons, which have been located above the power button and, to activate them, it is necessary to stretch out the hand, endangering the grip.

On the opposite side we only find the tray to house two SIM cards simultaneously and a microSD card to expand the internal memory.

The most interesting thing is found in the lower part of the Samsung Galaxy M31 since here is the 3.5 mm headphone jack , the USB type C that provides data connectivity and fast charging, as well as the only external multimedia speaker that integrates this Samsung smartphone.

The unibody body of the Samsung Galaxy M31 curves darkening towards black until it reaches the front, where it meets a flat screen using a black plastic frame as an intermediary for the assembly.

The front camera is integrated into the screen by means of a drop-type notch that breaks the symmetry of the side and upper frames, while the lower part shows off a chin.

Broadly speaking, the design is exactly the same as the South Korean firm has been showing in its latest M series models, featuring soft, rounded lines and the presence of a unibody polycarbonate casing that covers the entire back.

The frames are in a hurry for a mid-range smartphone such as this Samsung Galaxy M31 that we are analyzing.

An outstanding screen for this price range

Samsung usually stands out for the quality of the screen that it mounts on all its smartphones, each one according to its category, of course. With the Galaxy M31 it was not going to make an exception and the South Korean firm maintains the same type of screen that it had already been using in its Galaxy M range phones from last year.

It is a 6.4-inch Infinity-U panel with an aspect ratio of 19.5: 9 with Full HD+ resolution (2,340 x 1,080 px) and Super AMOLED technology that improves quality compared to the IPS screens they mount its most direct rivals. Thanks to the AMOLED technology of this screen, the Galaxy M31 displays intense and vibrant colors, something that some users can perceive as oversaturated, and purer blacks that enhance the contrast. The intensity of the colors can be adjusted without major problems from the Screen settings of the operating system.

Overall it’s a good quality screen , although we found the screen tending towards a somewhat cool white balance to our liking, so we’ve opted for a Vivid screen setting with a slight correction.

The brightness level is really impressive for a mobile in this category , presenting an intensity typical of higher-end mobiles since, despite not having official support for HDR, the brightness of its screen does allow it to display this type of content and In fact, this function is automatically activated when playing HDR videos on YouTube .

Thanks to this high level of brightness, we have not had any problem viewing the content on the screen outdoors, even in full sun , showing a very reactive automatic adjustment that managed to adapt to different changes in ambient light quickly and accurately.
