Hey guys today I am sharing my personal experience on oppo a57.Guys please dont buy this mobile.it is overpriced.At that rate u can get urself a better smartphone.Moreover the company doesn’t give android ubgrades.The phone is still running on android 6 Marshmallow.The phone provides you 13mp primary camera and 16mp front facing camera.runs on marshmallow with 1.4 GHz Qualcomm MSM8940 octa core processor.The phone provides you 3gb ram and 32gb internal memory with dual sim nano+ nano , dual standby 4g+ 4g.The battery power of the phone is 2900mAH.The screen size of the phone is 5.2 inch with 1280 x 720 pixels resolution.So guys if u are planning to buy this then think twice before you proceed.urs well wisher??
