    My second cell phone

    Nowadays, after formatting and using a Google account and not having much on it, it was even possible to use it comfortably for basic apps like Facebook, YouTube, banking, etc. But when it's almost full, the system becomes so slow that it's almost unusable due to frequent crashes. I've dropped it on the floor, it's fallen many times, and even gone down a flight of stairs, and it continued working normally (always using a case and screen protector). But today there are much better basic phones that still receive updates. + I managed to run Minecraft 1.17 without crashing.

    Lousy

    I had it before and it was working very well until there came a time when the phone didn't respond well, including WhatsApp. Then it broke in early 2025, but for me it was a decent phone, but remember that it's a low-end phone from 2019, so you have to let it rest.

    Perfect cell phone for its time. It runs games fairly smoothly on a daily basis.

    Good cell phone for anyone, good camera, good processor, even though they say it's bad, it runs smoothly for all of today's applications.

Ki Cost-effective
Score
Not available
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.
