1) the screen is oled, I have never dealt with them before and now I tried it. yes, the black color is perfect, infinite contrast, there are no questions about this, but the main annoying problem is color distortion. open settings in light theme (or any white picture) and tilt the phone 20 degrees, white becomes blue-green. Let's say the phone is on the table, you want to see the time, tap on the screen, it lights up, and at an angle you watch your wallpaper with a distorted color, I still could not get used to such a "feature" of a device for 70k. at the same time, this distortion is not visible when viewed through the camera, so everything is perfect in the reviews on YouTube. 60Hz - you walk and envy Android users with their smoothness of 120Hz
2) edges - visually they look better, but in the hand the rounded case is better like in 10 and 11, for me tactile sensations are more important
3) faceid - one of those technologies that seems convenient until you start using it, it won’t recognize you in a mask, you can turn it off, but then enter the code every time, if you hold the phone horizontally, it won’t recognize your face
4) nightmod - if you take a sober look at the photos that are obtained, it is very far from reality, it looks like some kind of wildly processed photos with colors and noise twisted to the utmost
