F1s is the new flagship by OPPO . It is 5.5 inch variant and has the curved edges which offers a pleasant feeling to the user while in hand. The company has compromised with its safety and durability with its luxurious view the company also offers the pre installed screen guard and gorilla glass 4 which enhances the protection . F1s comes with the fingerprint scanner which was missing in the previous F1 model . OPPO also offers a LED by which you dont miss your important messages .It weighs around 160g which is quite heavy for a smartphone . OPPO F1s now operates on android os v5.1 and has an octo core processor which means no hangs and all the multi tasking is done with ease .OPPO comes with 16MP secondary camera and 13MP primary camera which means it will be heaven for the selfie lovers .This time OPPO has also taken care of the music lovers with their loudspeakers and active noise cancellation . OPPO offers various color variant such as gold, rose gold and grey which all look fabulous and have their unique premium look. OPPO does not disappoints the technical geeks as it offers 4gb of ram that gives the user an advantage to operate various apps at once without any lags . I personally use this phone which I got it from amazon for about 18, 500 INR and a free back cover .At last it is a great phone with all the necessary features which should not be missed .
