    Practical, 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.

    Good 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.

    Compare, 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)

What is a Ki score?
Ki is an automatic score based on the specifications and prices of devices. It is calculated using over 200 variables to rank smartphones, tablets and other devices from best to worst.
How do we calculate the Ki?

In this case, to determine the score we evaluate 5 general aspects:

  • Design and screen
  • Hardware and performance
  • Camera
  • Connectivity
  • Battery

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.

Does the Ki score change?

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.
