Hello friends, right now I am using vivo v3 4G smart phone. This is my first vivo phone and I am impressed by its performance, it is such a nice phone in this range I bought it for Rs12500 . It is a very handy phone and also very tough phone, it has 3 GB RAM and 64 GB internal memory, and the processor is 1.5Ghz snapdragon 616 octa core which is very good according to me I am using it from last 6 minths and it never hanged, and it has around 2500MAh battery which is not that good I think it should be around 3000MAh, overall it is good phone.
