Samsung unveiled a new smartphone in the M series produced by the company on Tuesday, February 25, 2020; The Galaxy M31, which is the seventh member of the family after the Galaxy M10, Galaxy M20, Galaxy M30, Galaxy M40, Galaxy M10s and Galaxy M30s, has many similarities to its predecessor, and here, too, a large OLED screen and a very large battery in one Plastic body is used. The main difference of the M31 compared to the previous M30s of this family is to be found in the main camera of the device, which for the first time in a smartphone outside the Galaxy S, Note and Galaxy A is clearly equipped with a resolution beyond 48 megapixels.
Available in black and blue, the Galaxy M31 does not differ much in design from the M30s, as mentioned, and has a large screen with Infinity U notch, small margins on the sides and top and bottom of the screen, and the number and location of rear cameras. It has not changed. The 8.9mm thickness of this model is still a bit higher than expected thanks to its bulky battery and weighs 191 grams, which is not a light phone.
The screen of the phone, like the M30s, measures 6.4 inches (16.21 cm) and has a full HD Plus resolution and is made with Super AMOLED technology. The maximum brightness of this panel is announced by the manufacturer, 420nits, and the Gorilla Glass 3 cover also protects it.
The notch area at the top of the screen uses a 32-megapixel selfie camera, which doubles the resolution of the M30s, and adds 4K shooting and slow motion capture. Apart from its main function, this camera is also used to detect faces and unlock the screen in this way.
On the back of the phone and on the left side, we find a set of four camera lenses, the number of which is one more than the M30s, and there are changes in the resolution and type of cameras; The main change is the 64-megapixel camera (apparently the Samsung ISOCELL Bright GW1), which replaces the 48-megapixel camera on the M30s. This camera apparently comes with a faster lens, thus offering higher quality on paper than before. The Ultra-8-megapixel camera with 123-degree field of view has not changed from the past, and the 5-megapixel depth-of-field camera remains in place. Apart from these cameras, we come across a new 5-megapixel camera for taking close-up (macro) images that was not present in the M30s. The phone’s fingerprint sensor is also located in the same area next to the camera set.
Unlike the camera, Samsung has shown no interest in improving the specifications of the M31, and the phone still uses the relatively old 10-nanometer Exynos 9611 processor with A73 and A53 cores. The RAM of this model is fixed at 6 GB and has 64 or 128 GB of internal memory. The microSD slot is also not forgotten in this phone and through it, the internal memory can be upgraded to another 512 GB.
Another strength of the Galaxy M31 lies in its battery, which, as in the past, with a capacity of 6,000 mAh, offers high durability on paper, and from Samsung’s point of view, regardless of the type of user use, it will be suitable for a full day. The official announced times for this battery include 21 hours of web browsing with WiFi, 119 hours of music playback, 26 hours of video display and 48 hours of LTE network calls. This battery is charged by Samsung’s usual 15-watt charger.
