Oppo simply called a simplest phone of indian market. it is useful mble, good battery back up and it has low light perfomance camera is good and what they u have compared to this mobile it was awesome front cam clarity, its specification is too good, and it has struk less mobile. ewally I like it so much, if I have share my experince guys with oppo f1s get back to result today. if u might they have open too much apps then working perfectly.
