This phone is recently launch by oppo . It is quite best phone . The camera is best 10 out of 10 . According to the 16mp camera is best phone. And if any one budget is less then 20000 then you must buy this phone it is best phone under 20000. It not hanging phone becouse this cpu is using Octa-core ( 4x1.7 GHz Cortex-A53 & 4x1.0 GHz Cortex-A53) and 4 gb ram it can easily supported any game without lag . But only 1 thing is not good is that the android is 5.1 lollipop . This phone is in 2 colur it must be 3 or more colour them also white and gold is good . The radio , bluetooth and usb is supported . Best thing is that screen is gorilla glass 4 .
