For me oppo f1s is the best until which is being launched by the the oppo company .Best part with the phone is his 16 MP front camera which is very impressive and RAM of 3 GB which is also good . It have a superb sound quality and cant be compare with any other phone of same range.Due to 3 GB RAM it is very fast to access .and doesn’t hang at all .The design of this phone is quite similar to Apple iPhone 6, a slightly change in the button in the display which have a fingerprint senor . A lot of new feature is given like a new way of snapshot and may other .IT’s best phone within the range of 17, 500-18, 900 rupees of Indian currency
