It is the awesome android phone in his own brand. I suggest that you should buy it. This phone has a great features .it comes with a 64GB of internal storage and 6GB of RAM which is perfect for a android user. It has a dual rear camera of( 48 + 5) MP and a front camera of 16 MP , nice performance and it allows you to do multi task at one time without any sweat breaking. Oppo has a FHD display of 6.5 inches which is nice for watching HD videos , and you can use 256 GB of internal expandable memory .but it's price is somewhat costly for a normal person to buy it, and due to the big screen it can't adjust in a normal pocket .it gives two slot of 4G & 4G( dual Nano sim) .Resolution of touchscreen is ( 2340 × 1080) pixels. Good phone but price is more that we can't afford. Even this is a good quality smart phone.
