    There are better options

    The truth is, a very bad cell phone for what it offers. There are thousands of better options for a similar price to this one. I would consider it to be a good option for people who rarely use cell phones, for secondary uses, or for children.

    Pros

    It's a very bad phone, I don't think anyone should have a phone like that.

    It's slow, not very powerful, it crashes a lot, it doesn't usually load games properly, it has little memory, and it's not very useful for everyday use. If you just want to call and send messages, it's perfect, but for the rest of things it's not good enough.

    Pros
    • It is quite resistant

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.
