Im using vivo v3 since last 2 months. As compared to other Chinese or Android phones below 15k. This one is best phone. first if you buying a smart phone above 10k. That should have classic cemara. In this particular phone you r getting 13 MP back and 8 MP front camera. With lots of staff s like auto focusings, Motion capture, beauty mood and etc.
Apart from camera. you are getting 3gb ram. 32 gb internal( 24gb usable) .Snapdragon octa core processor. With lighting fast fingerprint scanner.
3.5mm jack.
Must tell you guys the ram management in this phone is very good and efficient. It have 2550 man battery. If you buy v3 you will come to know that maH doesnt matters too much. Because its battery backup is simply awesome.
Its never hangs out till now.
Security management is also good. Vivo using their default asps for ram cleaning and app locks.
Another feature I have found in this phone you can able to take long screenshot. Like 15 pages in one short. Simply amazing phone with lots of Features. Im loving it. Go for it.
