Hi friends I am using vivo v3 from last two years I am fully satisfied with this phone as per my work and used
Vivo v3 has five inches screen size which is very comfortable to hold and also having lot of feature which are very useful for our life as smart pick up etc.
Both camra back and front picture quality is good but battery backup is reduces after two years it should need to be improve, all necessary sw and feature are available in this phone one more important things about vivo is that if Viom said about three GB Ram its means all three GB are empty including all phone company install software as whatsapp, facebook etc.
