Oppo really needs to improve their smartphone line as what they omly focus on is their camera and look or style if I want a better smart phone I would require a smooth working smart phone with the faster processor and likely Better ram. As one of my friends bought this device I used it and it started laging on even not so heavy game like hill climb racing this phone really over heats in small time which is not good for a smartphone at this price range and will be a waste of money. This phone needs a huge yon of improvements.
