I owned Oppo A57 one month back. It’s sound reception is not so much good as compared to other smart phone in this budget. After one week it’s sound reception is not working properly. It is not so much user friendly almost it is not user friendly. It’s style is not special or unique and nothing impressive in it’s style & design. It works on android operating system and it has not any other features but it’s camera is good. It’s look is not good or fantastic and for this it feel you shame. It’s price is so much high [means costly] for this types of smart phone. At last I recommend you to not buy this phone.
