  • The best feature is the pretty glass back

    In 2019 you can get much better phones for this price. See UMIDIGI f2 and UMIDIGI Power instead.
    I got this phone about a year ago, it had the best specs for it's price at the time. The p23 wasn't good demanding games, but it was surprisingly smooth when doing social media, 2d games, etc. The GPU just wasn't great.
    I used it for about six months, then one day it fell out of my pocket when I was sitting down. The screen cracked even though the phone only fell like two feet! A few months later the entire screen came out of the frame and I got a new phone.
    White using the phone, I also noticed that the dual Camera system is fake. I tried covering the bottom lense in bokeh mode and the phone didn't tell me to stop. Taking photos in bokeh and regular mode made the same image. The camera sucks at night, too.
    The phone is good if you discount the camera. The big screen is nice and the processor is good. Screen is bright. But since mine broke and the camera is fake, I would recommend it.

    What a nice phone. Battery last all day no problem. Display is nice. Sound is good. USB-C. 3.5mm jack. Small phone with big display. Wish it got Android 9.0 but I guess it's not gonna get anymore updates. Camera is surprisingly good.

  • Good looking, but not worth the price.

    Phone looks great, feels good in hand (Slippery do to glass back and steel side).
    average screen.
    bad call quality (background noises even when you are dialing!)
    battery lasts only for 2 days with 2 hours music and around 1 hour wifi use, even less if you use GPS.

    selfi is good, but standard app is not recommended, better to download one.
    main camera, all the time blurry 1 patch got it fixedand its back to being blurry again even after downgradeing or setting it back to factory defaults.

    it comes with a black silicone case (looks good)
    and a protective film for the screen.

    if you really want this phone be prepared to install custom rom,
    factory ram is Androind 8.1 hoever with no bloatware, however camery is bad and phone sometime lags.

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.
