Vivo is a company which only only and only runs on marketting .
The price is almost 18 thousand but for that price u get mediatech 6750 chipset which is totally outdated.Even the chinese companies don't use them .This u may not know while buying a phone they only say octacore prosesor and not only that in the official website they don't even mention about that .U will come to know about that when u will downlpad some apps like CPUz etc.
They say 4gb ram but they dont say that they provide u with 4 gb DDR3 based ram which is also outdated.
They say that the display is very nice easily visible in sunlight but u know the display is just 720p hd display which is not full hd.
The only highlight is the frontfacing camera only for selfie . The back facing camera is also not good .its just 13 megapixel and that also without laser auto foucus . CONCLUSION
I strongly recomend don't buy this phone . if u just want selfie camera then add some 5000 rs and buy ur self a dslr.
