    Seems high end

    It is a very round mobile in all aspects. The screen excelent its maximum illumination the always on display very useful and looks very good. The unlocking many criticize him but he grabs his hand to the location very easy and is fast enough. The sound very strong and sharp, excellent. The cameras all very good although the telescopic and wide angle costs them in low light in addition to the second they have no night mode and the 900fps slow motion seems tricky and half difficult to hit at the moment that records at that speed although it looks good and in 240 It looks much better and is easier to use, video recording in general very good and stabilization the same. It is beautiful. The front camera also looks great and the retractable system also works very well and is fun close to a fall and from the height of the waist comes to close and if we press it is also saved. The buttons have a good touch and do not dance. Fast loading excellent.

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.
