Vivo V3 is the best smartphone made by the Vivo till date. I am using the V3 for past six months and the experience is just great.
It has a 5 inch which is not too large and not too small. It just feels perfect in your hands. The size of phone is very comfortable.
It has a octa core processor with 3 gigabytes of ram and 32 gigabytes of internal storage, expandable upto 128 gigabytes.
Battery backup is just great. The internet is always on on my phone and it lasts more than a day. Also it supports fast charging which is just awesome.
The picture quality is also good. Overall its a nice product and have very good features.
