    For $ 215 records Slow240fps / SuperLento960fps and 4K (30fps)

    For $ 220 or less .... I like the performance despite its 4Ram never fails in social networks but you can extend the internal memory up to 512GB, you can protect it with any case, the construction materials give you confidence to use it freely, I have not been able to drain the battery with 12 hours of use testing Samsung applications etc, you can record videos up to 4K and share on any smarttv screen, excellent and those 32MP-F2.0 / 64MP-F1.8 of your camera stand out day and night, Today February 9, 2021 it has 1Ui 2.5, patch 1Dic2020 and on the waiting list for Android 11 in 1Ui3.0, you can charge it at any time and you will get good levels of charge for its large durable battery I like the gesture of the fingerprint sensor to see the notification panel, has DOLBY ATMOS AND Always on Display

    • Will not lose value
    • $ 215 Price is right
    • recognized brand
    • Unsurpassed 60Hz display
    • no need macro lens
    • The fingerprint sensor manages the notification panel
    • No Protection A / P67
    • 1UiCORE instead of normal 1Ui
    • 20 clipboards missing
    • Last version missing NOTES (Although it works fine)
    • more options are missing in editing to edit video / photo
    • It can be improved, but I don't need it.

    The best smartphone in the range of R $ 1300 ~ R $ 1400

    This is the most balanced smartphone in this price range that is already in Brazil. Good cameras, battery that lasts a whole day of very intense use, being part of it heavy games. It runs most of the heavy games I tested at medium / high and has a simply sensational screen, very vibrant and colorful, and the maximum brightness is very high. It has a good sound with bass, it seems almost stereo. It is beautiful despite being plastic. Handles many apps in RAM. The only problem is that it heats up when playing heavy games, but if it runs in battery saving mode, it heats up less, and also, it takes a while to charge because of the 15w charger, but you will probably charge it at night then it is not such a problem, as a few minute charge guarantees many hours of moderate use.

    • Full day battery for heavy users
    • Incredible Super Amoled Full HD screen
    • Good cameras
    • Good RAM management
    • Satisfactory sound with bass
    • Shoot in 4k from the front and rear
    • It runs most heavy games, but it heats up
    • The flash is not very powerful
    • The charger is 15w instead of the 18w supported
    • Chipset does not yet support Gcam

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.
