View answers- AutoA phone ahead of its time
Whether for its impression sensor under the bluffing screen, its instantaneous facial recognition but not bewildered by a simple photo or video, by its photo quality easily rivaling the market's top, or by its screen just sublime , for its price (500-530 euros with delivery in France, I used oppomart that I highly recommend) I can only recommend this phone to who wants a unique smartphone of rare quality.
Pros- The camera
- The SUPER AMOLED screen
- The borderless designer
- The fingerprint sensor under the screen
- Instant facial recognition
- The fast charge that bears his name
Cons- Funtouch OS: some well-hidden settings and a pasted copy of ios #TeamAndroid
- Compatibility in France: phone in English
- The creation of an account vivo: contact the support
- The screen pulls a chouïa on the red ...
- ... but it's really to quibble

Score
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.
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.
