Oppo A57 is a mid range device which is poor performance device. the phone is powered by a low end processor snapdragon 435 chipset which results in slow and poor performance of the phone. the phone looks like a copy of apple which same design, but the feel and texture of the phone is quite cheap like poor quality metal. the display of the phone is 5.2 inches which is good but downside is it comes in a low resolution of only 720p which is very low for a 5.2 inch display. the phone lags a lot and it overheating after regular use after 30 to 40 minutes of running. the camera is vibrant but not clear. the photo looks very artificial taken from this phone. so overall I don’t recommend it.
