My bro use been using Vivo V3 for over a month and I am really impressed. The BEST part about this phone is its software FunTouch OS. It has tons of feature to make everyday use of phone very easy. V3 has built in call recorder and call blocker . It has excellent security features. It has built in firewall and app locker. The call quality is very nice. The 3GB ram helps in smooth operations. Camera is statisfactory with nice video features such as ability to shoot video is slow motion as well as fast motion. Gaming too is decent with no lag or major heat up issues. Battery life is bit on minus side. The built in video player has the same features as Mx Player. Hence I did not feel the need to install it.
