    Low-mid-range telephone at a medium or high average price

    It has a good screen, as is almost normal for Samsung, a battery of 3,000 that should be sufficient without demanding use, but thanks to the poor optimization it does not hold a day of use and the applications that we can not remove, unless we change the room, or being root, it is impossible for us to uninstall everything and the 16 GB that it offers us, it is insufficient for us to use, it has a good daytime camera and good video quality but this, and the little storage that we are left as users, it is almost mandatory to buy a micro sd

    Positives
    • Amoled display
    • Double chip and micro sd
    • Front flash
    Negatives
    • After a short time of use I can not lower the brightness, since the lower half begins to combuste and this worsens every day
    • Optification
    • Overheating
    • Drums
    • Apps that we can't remove

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.
