I am using oppo f5 youth. Its a best offline snartphone for aeffective price range. Good battery backup , full screen , fast processing amazing camera. 16990/- not any best mobile in this price range who beat oppo f5 youth. I am very imppressed with quality theu are provinding f5 will rock. 1080p phones with a huge batteries should be pushed more at low prices. It is very intelligence rare camera. Best camera quality. I like this phone beacause so light weight and long battery and fast browsing internet.
