    "good"

    It is a somewhat good device, good in question if you only want it for work and data movement use, but for gaming I certainly do not recommend it. To be honest it's a good device, but I think it could have been better, although the front flash is something very cool. In the same way for photos it is defended, only that at night it is not recommended if you do not want to use the flash.

    Good

    It is a mobile with good design, a nice screen, but it is ticked and it gets slow, being new, I have a Huawei p 9 lite from 2017 and in terms of fluidity and performance it is incomparable. It also has android 8, it should have 9. A mobile with some limitations.

    Positives
    • Design, screen and agile.
    Negatives
    • Increased performance in heavy applications and on-screen color adjustments.

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.
