I have been using the v5 s phone of vivo since 2 years and in between this 2 years I didnt face any hanging or slow related problems its 4 gb ram enables a fast processing work on this phone.i feel I am a lucky user to use a phone with such features it includes.its music is awesome.It has 20 mp front camera with portrait mode and have many more camera features such as professional. slow.and many more it also provides us a sexy sound system inside our phone.But as per the phone the battery is relatively less. It has dual screen mode where we can use two apps at a time.you can chat with your loved ones and even watch videos. Song at a time in the same screen. Its camera also has a great focusing capacity.The headphone of this phone is also awesome too.This phone has an unique feature of hifi which allows us listen music With the highest audio quality.It has finger print sensor on the home button which plays a great role in people's demand as because many people doesnt like fingerprint lock at the back. It is an awesome offered by vivo. Which is only meant for music and camera. This phone is the best product of vivo to buy at a medium range
