Well oppo f1s comes with 4gb ram, 5.5 inch display, 64gb ROM and 30000mh battery .As I said the overall view and specifications are good but the phone comes up with heating problem which is major problem for user, especially for those who surf net 24x7.The best part of this phone is its camera.If you are looking to buy this phone I strongly recommend you to buy vivo v5.
It feels sad when you buy phone for 18k to 20k n it comes up with this kinda problems.
