The phone is amazing and best phone at the rate of 25k the specs of the phone is pretty amazing and the fingerprint sacnner is pretty effective. The display size of the phone is 5.5 inch which is a large screen and the display quality of the phone is good.
In india oneplus provide oxyegen os which is mostly like the stock android but you can change the os just by installing rom through the recovery mode. I have been using oneplus two from last two month and it is the best phone that I ever used untill now.
The phone is amazingly good and worth of buy
