Samsung Galaxy M31s Hands-On Review: Price and Specs

Samsung Galaxy M31s

The is the latest in all too similar phones from Samsung. It is the upgraded Galaxy M31, identical to that of the M21, and upgraded to the M30. All these phones are very similar, almost identical with some bits switched around, and have all been introduced over the course of one year.

So what’s the situation with the Galaxy M31s? Well, it seems despite the overwhelming similarity on paper, the Galaxy M31s seems to have a different body this time around, even though it oddly doesn’t look all that different at first glance. Yet, there are enough changes here that need to go through a fine-toothed comb. These changes do subtly change the way you use the phone, so they aren’t insignificant.

But as mentioned before, the Galaxy M31s is very similar to the other two phones, especially the M30s, in terms of hardware specifications. The display, the chipset, the memory and storage configuration, most of the cameras, and the battery are all identical across these models. This means if you already own a Galaxy M30s, then you really aren’t missing out on much with the Galaxy M31s.
