Pick the Galaxy M31 up and it feels comfortable to hold in the hand. The sides are slightly curved which helps with grip. Samsung has positioned the power and volume buttons on the right of the device. The power button is easy to reach but the volume buttons could have been positioned better. On the left is the SIM tray which did not sit perfectly flush on our review unit. The Galaxy M31 has a 3.5mm headphone jack, primary microphone, USB Type-C port, and speaker at the bottom. The top only has the secondary microphone.
When you look at the back of the Galaxy M31, you'll see some changes. The camera module is similar to that of the Galaxy M30s but it now packs a Quad camera. Next to this is the fingerprint scanner which was comfortable for us to reach while holding the smartphone.SPECIFICATION
