    Good camera, not very good screen and excellent battery

    The camera is good during the day, at night it is not. For games it only works with not very demanding ones, the screen quality is not perfect but not that bad either. The battery is too good, it lasts more than a day. The sound is not very good, it is low and it does not sound very well.

    Powerful mobile at the height of the best

    After several weeks of testing, I am very happy with the mobile for its fantastic qualities: - Very nice and modern design without curved lines and in my case in a beautiful white a little iridescent color. - Screen: the screen has preceded me perfect, elongated and large enough of 6.5 inches to see everything in a good size and perfect. - Despite being large, the mobile is not very heavy (192 grams) and is easily handled with both hands and one. - The battery has surprised me a lot, it has 5000 mAh that last up to two days, I also really liked the fast charge of 18. -Another pleasant surprise I have taken with the cameras, it has a module with four lenses in the back, the main one with 48 mp and the front camera with 13 mp. You can take photos in portrait mode by adjusting the blur,, macro, food, panorama and pro. It has an 8-core processor with 4 Gb of Ram and 64 Gb of storage so the mobile is very fast. I recommend it.

    mobile 10

    This mobile has pleasantly surprised us. Due to its large screen size that makes it perfect for checking emails, photos, reading ... due to its system speed. But above all the camera is spectacular. Photos come out with professional quality. It is capable of capturing moving images with great clarity. It is far superior to many high-end mobiles. The battery lasts a long time even in operation and its recharging is done in half the time of our previous mobile. I would recommend it to anyone. It is a purchase of 10.

    Nothing to envy to the high end

    It has a very elegant design, it weighs nothing, the screen is excellent, it has the best cameras that I have been able to try, and a lot of positive things. In short, it is the best phone I have tried to date. I love its infinite screen, the position of the camera and that it is only the perforation of this for me is perfect since not being in the middle gives the feeling of having the whole screen complete.

    A smartphone with very good qualities

    After a few weeks testing the Samsung A21s I can give my opinion on it. The size of the Samsung A21s is large, previously it had a Samsung of the J series. Its design is very modern with a rounded shape, hence, although its size is large, and its weight is light, it is perfect for its grip and can even be used with a hand, on the right side it has its buttons for volume and lock. Its screen is 6.5 "and it is an infinite screen which I liked a lot since to watch videos, play etc the experience is very good if you have to put a serious problem that outdoors although the brightness is at maximum it is difficult to appreciate the content In summary, in normal conditions, the image quality is very good for all the features that it offers us.

    I love it

    I have had the new Samsung galaxy A21s for days, but I have noticed slight differences with other models I had at home, the battery charge is very fast and I can take "perfect" photos without having much knowledge of photography. The screen is huge and allows me to watch series, YouTube and make video calls seeing all the details.

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.
