Outdated Product
A long-lived smartphone with a powerful battery, ambitious hardware and a quad camera on the back. But first things first. The crown "trick" of the model is a 6000 mAh battery with support for a 15-watt "tank refill" Samsung Charge. The manufacturer claimed two days of battery life of the smartphone in the mode of telephone conversations and up to 16 hours of screen activity when playing video. From the face of the Samsung Galaxy M31 128GB, the user is greeted with a large-caliber screen (6.4" diagonally) based on a Super AMOLED matrix with bright and rich colours. Taking into account the proportions of 19.5:9, the picture is displayed on the gadget's display at a maximum resolution of 2340x1080 pixels. In the bowels of the body of the device, a home-grown “octa-core” of a strong middle li...nk Exynos 9611 is installed. And in terms of memory, the smartphone got hold of 6 GB of RAM and a built-in storage of 128 GB. A 64 MP matrix has been assigned to the role of the leading photomodule of the quad camera of the mobile device. In photography, it is accompanied by an 8MP ultra-wide sensor, a 5MP macro sensor, and a 5MP depth sensor. The device shoots self-portraits at a 32 MP front camera, the lens of which is inscribed in a teardrop-shaped display cutout. One version of the smartphone also has an NFC on board (model with article number SM-M315F/DSN).

In my opinion, this phone can easily be used for both work and gaming.

Great phone for its price. I would say it's even better than some Xiaomi phones that cost 10,000 UAH.
An awesome camera.
A cool OLED display.
Beautiful firmware.
A sufficiently powerful processor.
Plastic frame and back.

The phone is worth the money

Personally, I like everything
The battery holds up decently, all games are played in 6 months and I haven’t encountered any problems
The camera's built-in filters do not provide the saturation and contrast that was expected, but in general the picture turns out good if you increase the contrast and saturation in the editor

If you come to terms with all the downsides, it's a good model.

Processor is not top-notch, but it's fine for not-too-long gaming sessions because of overheating. The battery is excellent. I love One UI, and the screen is quality AMOLED. Of course, it's not glass and metal, but I carry it in a case. I bought it because these drawbacks didn't stop me. The camera is decent for its price: the main sensor works well under good conditions, the wide-angle is okay, and the two fillers are like everywhere else. The sound is average. You can add €74 and buy the M51, which is even better.
Battery, screen, firmware.
Not very fast charging, sometimes overheating

Under the wing of the Galaxy M series of the South Korean brand Samsung, long-lived smartphones have sheltered entirely. The senior model in the line as of the first half of 2020 bears the serial number M31.

Cosmetic update

The smartphone was released as a cosmetic upgrade of the popular Samsung Galaxy M30s. They borrowed a juicy screen based on a Super AMOLED matrix with an Infinity U-style waterdrop notch, an “iron” component with a homegrown Exynos 9611 chipset “at the head of the table” and a 6000 mAh record-breaking battery. So that the process of charging the battery does not stretch for long hours, the gadget was “delivered” with support for Samsung Charge technology (accelerated charging with a power of 15 W).

Camera with the prefix "quad"

Of the innovations, the model increased the amount of memory (up to 6/128 GB), got a separate slot for a microSD card, and acquired an additional “eye” of the main camera. From now on, the rear photomodule has a “quad” prefix: the choice fell on a 64 MP main sensor, 8 MP ultra-wide, 5 MP macro camera and 5 MP depth sensor (for effective background blur in portrait photography). In the centre of the plastic “back” of the device is a platform for a fingerprint scanner.

Out of competition

The addition of the Samsung Galaxy M31 provides a full range of wireless communications (including the NFC chip in the most "running" modification of the smartphone) and support for the Google AR Core augmented reality service. With such data, the model simply does not have direct rivals in the league of solutions from A-brands.
