Vivo is a multi billion mobile company from japan which is being very successful in India. I bought Vivo V9 3 months ago. After using it for 1 months. I think this doesnt worth the money this phone is totally over priced. PERFORMANCE-It is powered by Snapdragon 626 processor which is enough for the normal user but not for high end gamers and hard core user.
Two sectors in which this phone is good that is camera and display.
CAMERA-It has rear dual camera( 16Mp + 5Mp) this combination is pretty good for every photo lover. Front camera( 24Mp) vivo is always known for its selfie camera which keeps going with this device.
DISPLAY-Its display has notch which looks pretty good. With 16: 9 Fhd+ resolution makes phone with good in display
My Opinion- I would suggest you to not to buy this device because things which this device is giving are being given by other manufacturer like Xiaomi at 10k less than this device so dont waste your money look for good options in market.
