Oppo is a wellknown chinies company which provides specially good camera phones.But Oppo A57 is not good as it’s price.I bought this phone last month to gift my wife, but it has lots of issues.Oppo A57 hasn’t support direct video calling, It’s battery backup is very poor, .It comes with 5.2 inch display with 3000mah battery.Processer is 1.4 only but price is above 15000.In this phone also heating issue while suffering on net for 20 to30 minutes only. very bad experience with this phone.I suggest everyone who read my review, never go for this phone.You can buy Redmi note 4, or samsung on8, which are far better option.
