I personally use vivo smart phone v 5 its prize was 17980/- its Ram is 4 gb , internal memory is 16 gb and very userfriendly to use , sound clarity also. Good I have never face hang issue and its available on zero intrest on loan , so its experiance is realy owsam and you can use many browser at the same time , when u see movie u dont need to go back n see message u directly put message without stop movie , so I m realy happy to choose my Vivo 5 . Its wow experience. Battery back up also good.it is going for full day .
