Oppo f9 is my latest smartphone.
Cons -
User interface by oppo is pretty boring
( Camera)
Camera tend to make photos more saturated and warm.
Lose of details
Portrait mode is garbage
( Looks)
That notch looks stupid, I prefer a standard notch.
( Performance)
Full of bugs
When you start to use the f9 as your daily driver you start to notice alot of bugs here& there
Hope oppo fixes it with future updates
Lags
Phone shows small lags while doing hefty tasks
