Hi guys in this review I wanna share some of my opinions on oppo f1s.i think this is not a good phone at .we all know that oppo is still down in stock market in producing great products.at last this oppo company have launched oppof1s which is only good and exelent in camera and music .my mom have buyed it two months ago by the first day the optimaisation of ram is very very poor.they say that its coming with 4gb of ram.and one more bad thing about this phone is storage its coming with 64 gb of rom but over all its only with 51.56gb of rom .what a worst thing.i will not prefer to buy it .its a bad product from oppo.
