    Mediocre in every way. almost bad.

    It was my last LG, and the best of the three I had because the other two were a m#€+&@. The design was nice, plus it was military certified, and the sound was pretty good, but that's where the positives end, as the battery was poor, the memories insufficient, the layer complicated (and on top of that, it was full of useless advertising and bloatware), the plain display, the horrible cameras, and to top it off, the performance was enough not to freeze (the P22 is similar to the SD625 in my old Nubia M2). At least I was getting regular updates. I do not recommend it today for any reason. There are much better options at affordable prices.

    Pros
    • Sound, mono, but very powerful.
    • Well built design.
    • military certification.
    • Regular updates.
    Cons
    • Fair and necessary performance.
    • Horrible cameras.
    • poor battery.
    • Unfortunate screen.
    • short memories.
    • Complicated layer full of bloatware and advertising.

    Decent cell phone, although in the time of 1 year or more it begins to fail

    This cell phone was given to me 3 years ago, and although I am very fond of it, it does not take away from the fact that it has several errors and a very low power, after 2 years it was when I noticed major failures in the cell phone, it gets stuck a lot, I can not install things, it got me locked up too much just being able to use social networks (and that also gets stuck there)

    Pros
    • Withstand falls and bumps
    Cons
    • Poor software quality
    • 4.6
    • Screen6.5
    • Performance3.0
    • Camera2.2

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.
