I am using this mobile for more than 6 months and also writingy revoew from this mobile. Through my personal experience I say that
This is one of the best product of oppo.
This mobile has 5.1 lolipop Android
2gb ram.
16gb rom.
It gives u a look similar to iphone, like it has its own o-cloud but not as functional as iphone does.
The most favorite thing about this device is its camera.
U could have the best experience of photograpy with its 13mp amazing camera quite favourable for selfie lovers.
Oppo offers a bunch of lock screen wallpapers. Seriously You won, t find it in samsung or huawei. Another most surprising thing about it is it, s battery time. It gave u a long lasting battery time n better then many other smart phones. I surely recommend you this mobile to fulfil all of ur required demands
