Outlooks matter especially when you purchase an electronic gadget and this " matter " has obviously pushed the companies to take the design descriptions of a gadget to an another level. Samsung, as you already know, has always built their face as a company that engineers products with a premium-level look . And when it comes about Samsung Galaxy M31 model, it's almost next to impossible to overlook it's physical glow.

Dimensionally, it counts 159.2 mm x 75.1 mm x 8.9 mm ( height x  width x thickness ) . It weighs 191grams, that's quite a heavy one and you will feel it's bulkiness in your hands while you hold it. Samsung Galaxy M31 is enriched with two different colours , i.e., Ocean Blue and Space Black. And meanwhile, you are being served with an odd, that is, it's rear part is inviting in nature.

But, what does it invite ? It invites your fingerprints whenever you hold it as it's rear part is glossy in nature and cannot avoid the settlement of finger marks. What you can do is just keep a small piece of cleaning cloth with you wherever you step out of your house and use it to clean all those smudges. This will help the rear part to remain smudge-free, otherwise, spots could become permanent on it.

Sides are slightly curved to lessen the pointyness and becomes friendly to your holding hands. On the right side of the device, power and volume buttons have been placed and on it's left hand side, sim slots exist.

At the bottom part, you will get 3.5 mm headphone jack, primary microphone, USB Type - C port and speaker . On the top, you will get a secondary microphone. Now, in meantime, I would like to give you a short clarification between primary and secondary microphone, in terms of its uses. Primary microphone comes into use when you talk in your mobile phone without speakers. On the contrary, secondary microphone comes into effect when you turn on your speakers while you talk. That's the difference in use.

Samsung Galaxy M31 won't dry up your curiosity of photography because Galaxy M31 has been made ready to shoot out quality pictures for your subjects. Galaxy M31 has been powered up with Quad camera set up on the rear part of it and with a single selfie shooter in the front part.

Quad camera set up consists of following :-

1. 64 MP primary camera ( f/1.8 aperture )

2. 8 MP ultra wide angle camera with 123°

field of view ( f/2.2. aperture )

3. 5 MP depth sensor

4. 5 MP macro camera

Single front camera is of 32 megapixel.

This is all about the descriptions of camera. But how much worthful will they be ? Let me give you the detail of their performance step by step.

Primary camera is good at its photography as it clicks decent shots with a fine clarity. Wide angle camera is also a good contributor but you can't believe entirely on its zooming capabilities as zooming results blur images which is obviously not acceptable to anyone. Remaining 5 MP depth sensor and macro camera produces fine-level photos. However, Macro works better in outside environment than the inside one.

In several cases of photography you need to separate the subject from the background and what we use for that is portrait mode that blurs the background. But, won't be it nice if you can set the amount of blur according to your needs ? In M31's portrait mode, it's possible to adjust the blur - level. That's quite good .

Selfie camera plays well and comes out with decent and clear photos with a concerned amount of brightness on it, despite the fact, it wouldn't remain a good shooter if photography takes place in low light. So make sure you have a proper lighting environment around you.

Scene Optimizer is a camera feature found in Samsung smartphones. Before explaining it, I would like to highlight the problem first for which you can prefer Scene Optimizer as a solution. It often happens that you are not able to capture a nice pic of a scene just because the camera mode that you have used to click was not appropriate for the scene you have shooted. Or, let say, that particular scene demands an another camera mode to get captured in a very nice way. How will it be then when you get a feature in your phone that automatically sets the best camera mode just before you click a pic ? Scene Optimizer does that and eases photography. You don't need to select the mode by yourself anymore. Works good in Galaxy M31.


Fingerprint scanner is positioned near the quad camera set up on the back of it. Address of the scanner is well appreciated because the fingers smoothly reach it.

There are some other applications present in this model like Digital Wellbeing , Parental control which are going to secure you to some extent.

1. Digital Wellbeing - an application that detects the mental condition of an individual when he/she interacts with the technology.

2. Parental control - if parents think that somehow if their phone get into the hands of their children and open that applications which they think that their children shouldn't come in contact with then they could hide those applications conditionally .


6000 mAh battery is really an mammoth for this device which makes the model a little bulkier. But, who can ignore it's performance ? Can you feel the gravity of it ? A battery of 6000 mAh capacity . Surely deserves " WOW "reactions from the audience because meanwhile you need to put your attention on its affordable price. To say in other words, the price at which you are getting all these features in Galaxy M31 is really commendable. Samsung Galaxy M31 stands for 2 days in a stretch without being plugged for charging. That's really nice .
