Vivo is the most selling brand in India.why many people buy vivo phones I don’t know may be for it’s good selfie camera. But only camera is not the matter. Vivo v7+ is not a good set at its price range.May be It has good camera but the battery life is not good. At this price range vivo doesn’t give full HD or amoled screen, which is a very bad thing. Processor is mediatech at this price range! Which differs the performance of the phone.
