Hi friends I was using the phone vivo v3 from last 4 months. It’s a great experience and the futures of the phone are better for me. It’s a 4g with dual sim. Supports all apps and you can run 5 to 10 email Ids at a time. And the Sim and memory slots you can insert very easy way, no need to open the back cover. It’s available in two colors gold and white. And surprisingly I got 2years warranty and also got a flip cover and a back cover. The video clarity is very excellent and sound is very clarity. Futures are good for office work.
