Oppo f1s is the best phone in its price range. The phone camera clarity is even better than Apple iPhone. The phone comes with octacore processor having 3 GB RAM and 32 GB ROM ( inbuilt) and external memory card up-to 128 GB and most of all have dual sim card option with 4G support. It has finger print password protection and o-cloud option as well. Definitely a smart phone for smart people. Good going OPPO.
