Hello friends, I have used this Vivo V9 smartphone for 1 week, and I come to the decision that I have maked a mistake by purchasing such expensive phone. This phone is having 4gb ram, 64gb internal storage and Qualcom Snapdragon 626. But it is not sufficient for 23, 990Rs. The battery backup is ok 3260mah. But one thing that is great is its front camera which is of 23megapixels. And at last I have to say that Vivo need to upgrade this phone.
