- AutoPractical, powerful and good value for money.
Design: more than acceptable quality despite having a plastic finish on the back, with a normal weight and an infinite screen only shared with the essential frames. Screen: the screen, in my opinion, is precisely one of its strengths. As I said before, practically its entire dimension is usable, with AMOLED technology, FullHD + resolution and with 6.4 inches that are more than enough to enjoy perfectly viewing photos, videos, games, documents ... and so on. Camera: the quadruple 64MP main camera, 8MP wide angle, 5MP depth and 5MP macro, together with a correct use of the settings, focuses and perspectives will make your photos truly spectacular and the envy of Instagram media;). Final conclusion: If you are looking for a mid-range mobile with great value for money, without a doubt the Samsung Galaxy M31 is the best possible option. You will be more than satisfied.Positives
- Screen, camera, battery for the whole day.
- Cover, battery life, notification led.
- AutoGood battery, spectacular photographs, ...
Serious, sober design, with curved sides and round corners, easy to handle in the hand, comfortable to wear. Its weight compared to my previous mobile is higher, Large screen, easy to view, bright colors, adequate brightness, something that I want to emphasize and importance is that its screen allows you to use the mobile under the sun with perfect visualization. The sound from its speakers is good, which can be improved, but the sound emits well and sounds good. Spectacular photos by day, at night they lose a bit of quality, and the image is reduced. Battery: The first week of use, with average use, the battery life was perfectly 2-3 days. The fast charge lasts about 3 hours to fully charge the mobile, this would improve it, being able to be even faster.Positives

- AutoCompare, inquire and decide
After several weeks testing the Samsung m31 smartphone, my opinion at the user level is the following: - The battery, which for me is one of its great attractions, withstands intensive use very well (calls lasting several hours, music in the background, use of internet, games ...). My old terminal had to charge it 2 times to last the whole day, with this I have plenty. - Camera, it has a great quality for my level of use that is at home (family photos, some landscape), things like that. If it detects documents you have the option to scan them, but I prefer to have a specific App for it. The photos are good and where it is most noticeable is when the photo is taken and you zoom in, the details are superior. I still haven't gotten to the point of the video and it doesn't seem like a big deal to me, but I think it may be a matter of time and learning. - In the time that I have it I have had 2 software updates and know that it is one of the smartphones that will be updated to Android 11 (it was to be expected)Positives
- AutoIncredible mobile at an unbeatable price
I've been testing the M31 for a couple of weeks now and I'm really liking it: The pack includes the phone, the instructions and the clip to remove the SIM / SD card slot. It would be nice to include headphones and a plastic case, as it adds more value to the product. -It has a 600mAh battery that lasts 2 days of normal use, it is a very large battery so the charge takes about 3h but thanks to the fast charge it takes much less. -Design: it is not especially striking, the blue color is quite muted although it changes tone according to the reflection of the light. I don't quite like the plastic finish because fingerprints and sweat marks remain on the back. It is surprisingly light for the battery it has. -Display: it is an almost infinite screen, without frames, with a great image quality and an intensity of colors that provides an incredible user experience. -Camera: I was very pleasantly surprised, the image quality is really good for both cameras.

- AutoI love it!
I love its design, its color, how light it is and, above all, the speed with which I navigate and open the applications. Its screen is great for my taste, because I like it with a big screen. The image quality is very good, it takes beautiful photos and I can do what I want, professionals. The battery lasts me more than a day and that I spend almost all day with the hooked because I work with him. I love unlocking with the finger, it recognizes the fingerprint at the moment and it takes less time than if I have to put the code or with facial recognition, which as with a mask or glasses does not recognize me because in the end you have to put the code to unlock.
- AutoDelighted with the Samsung Galaxy M31
I needed a mobile like the Samsung Galaxy M31, it offers everything I need for my day to day, processing speed, photo quality, fast battery charging, 6.4-inch infinite screen, Android 10 operating system and very nice, mine is red, I love it.Positives
- Photo quality
- Battery charge time
- Charging cable
- AutoVery complete: battery, quad camera, ...
Handy with one hand. You access all the buttons. The weight is adequate. The fingerprint works fine and the facial recognition works great even with glasses and something dark. Regarding connectivity, everything is perfect. The playback of the various audio and video formats is also great. 64 Gb internal memory is more than enough, but if you want more, you can put an external memory card. Slot for 2 SIM and 1 microSD. The large screen and the color and resolution are fantastic. The battery is amazing, it lasts the unimaginable. Much more than expected and using it a lot. And in case you run out of it, the fast charge means that in a very short time you can use it again for a long period. I have been 2 whole days and with a lot of use. The issue of the quad camera is also another level. You have all kinds of night modes, macro, slow, super slow, wide angle ... And video in 4K. And the front camera will make selfies look like they were made with the rear camera.Positives

In this case, to determine the score we evaluate 5 general aspects:
- Design and screen
- Hardware and performance
Once these 5 factors have been rated, we introduce the price variable. This means that any two devices with the same ratings get a different Ki score for quality vs price.
Even a device objectively worse than another may have a higher Ki score if it has a better price.
The Ki varies as time goes by. As new devices with better specifications enter the market the Ki score of older devices will go down, always being compensated of their decrease in price.
