Oppo is a very bad brand .Oppo have not basic features like other Android samsung, xoami mi, etc. Basic features is calling without net video or voice call to any other Android device without third party aap.Because everyone not use third-party aap, and everyone not turn on data everytime.Battery backeup is bad.Camera is not good.Fake ads on tv and site are oppo camera phone.its a name only. I suggest those 'who wants to buy oppo' don't buy because very expensive, features is not in it and wasta
