Oppo A57 is one of the best handset I ever used, it’s was really attractive and nice designed, the camera was best in best, it’s picture and displayed was so fine. Oppo A57 is really a great mobile I had using, nice battery backup for long hour, Good headphone and perfect charger, It’s charge very fast and last long time your battery, very good Android version, high capacity to control your phone virus, best screen lock and security. I really like and enjoyed to buy oppo A57 mobile and also every of my friend use it.
