I bought the phone just after the launch. This my first oneplus device. The first the thing we notice is speed of the device. It is the fastest device that I have used.
Display
It has got killer display. Because of the 90 Hz display, everything feels smooth. The colors in the screen is also good and vibrant.
Performance
I already mentioned the speed of the device. Heavy games run smoothly. It never got stuck . The software is clean and fast. One of the best software I have seen.
Camera
It has got a above average camera. The night mode is pretty crazy, it takes great photos at night
The most crazy thing about the phone is charging speed. The best I have seen
