Guys lets talk about oppo a57. it provides battery backup of 2900mah, it provides resolution of 720*1280MP, internal storage is 32gb. Its front camera is 16MP & back camera is 13MP. Provides 3gb ram. it has heating issue. cant use for gaming as it gets slow some times, its style attracts. sound quality is also good. earphones is not having best quality sound delivery. hanging problem exists. system up-gradation is very time consuming. it costs too much. its interface is user friendly.
Thank you!
