One of my tuition friend have that phone and I have used it for sometime phone has good internal memory but is not a good phone to use. Firstly it has a huge weight also sometimes it gets hang little bit means stop working for a few seconds also I didnt liked its camera quality. One plus 5 is not the best phone as compared to its price.
THEME-friends its theme is not good it has a very bad theme. Also it has a bad display.
STORAGE -if we talked about its storage OK we can say that it has a good storage of having internal memory of 128GB and can be expanded up to 256GB .Also a very good ram that of 6GB.
CAMERA-It has an rear camera of 16 mp and a front camera also 16mp but I dont thought that it was having that much clearity in the camera. It has a single camera at its front and but of no use and dual camera at its back having a little bit of good quality.
DISPLAY-yes of course it has good display having a gorrila glass and also a 5.5inch screen so it has a benefit of having gorilla glass so that display will not break easily if filled by mistake also.
But its price is not good it is very high as compared with its specifications it should be less than what it is. So finally I only say that it is not a very good mobile.
