So finally here vivo launched a best phone.no doubt features of vivo v5s is so cool .eg.vivo camera is so good means 20mp front camera with ultra hd .cool sound.usable gestures.battery power.rare camera 13 mp.fingerprint sensor open within 2sec.mattle body .slim.nd other cool features.but the only one feature of vivo which is negative that is when the calling is the .phone lock easily open no security there.one more negative point that is direct viedo calling system not in vivo and other phone like samsung direct viedo call in present .its is one more negative pointbof vivo v5s but allo the features of vivo is so cool nd usable.for this generation vivo is best .??
