Samsung just launched its first M-series smartphone of 2020, dubbed the Samsung Galaxy M31. The smartphone focuses on tech-savvy young millennials and Gen Z. It is built upon the 2019-launched Galaxy M30 and M30s. However, we see major improvements in the camera and battery department. The smartphone is being called the ‘Mega monster’ by Samsung since it comes with a 6000 mAh battery and a 64 MP camera sensor.

Design and Display

Aesthetically, the Samsung Galaxy M31 is reminiscent of its predecessor, the Galaxy M30, spare for the squircle fingerprint reader on the back and the rectangular camera housing with an added camera sensor. It comes with a polycarbonate back casing and is available in Ocean Blue and Space black colors. Despite boasting a huge battery, the Galaxy M31  is just 8.9mm thick and weighs only 191 grams.

On the display front, the smartphone features a 6.4-inch Super AMOLED display with FHD+ (1080p) resolution and 19.5:9 aspect ratio just like its predecessor.

Internals and Storage

Samsung Galaxy M31 comes with the Exynos 9611 chipset at the helm, paired with 6 GB RAM and 64 GB or 128 GB of onboard UFS 2.1 storage. In case that’s not enough, it has a memory card slot as well.

Software-wise, the smartphone runs on Samsung One UI 2 on top of Android 10.


One of the highlights of this mid-range smartphone is its quad-sensor rear camera that comes with a 64 MP main sensor accompanied by an 8 MP ultra-wide sensor, a 5 MP macro lens, and a 5 MP depth sensor. On the front, it sports a 16 MP single sensor for selfies that sits in the waterdrop notch.

Battery and Pricing

The mid-ranger is powered by a massive 6000 mAh battery backed by 15W fast charging. It is not the fastest in the category but will perform reasonably well.

The smartphone will go on sale on 5th March 2020, and the base variant will set users back by $208 while the maxed-out variant with 6 GB RAM and 128 GB onboard storage will cost $222.
