Again oppo launched a new best phone OPPO A57. Design of this phone is very classy, I love it’s look from both side. If I talk about the performance of this phone that is very great. I am using it from last week and tested it evey where like antutu benchmark or other different - 2 applications. BUILD QUALITY of this phone is very impressive but this phone is little slippery but if you can use a cover then it is not. Battery backup of this phone average. I am a game lover person and I play games on it daily. Overall this phone is very good, camera is cool RAM and PROCESSOR are also work very fast, If you want to buy it then go head.;)
