I got a one plus review unit from one plus last year. The back of the phone is very good the roughness feels very good. It has 4 gb ram that can do multitasking easily.
When I booted the phone it took almost 25 seconds to open. Gaming is very good no lags at all. The camera of the phone is not so flagship but its good. Overall it is a great phone at 23000 rs. I would rate it 9/10.
