Here im the user of vivo v3 for past 3 months and I hace to say the design of mobile is done very nicely.it gives a premium look and feel.and now coming to performance the phone heats up a lot even for casual usage and sometime touch wont work and I encountered auto restart 6 times in my usage I think it due to heat.and camera focus is not good and some times when u launch camera it wont open.also sometimes background apps are getting killed.finger print works perfectly.i wont recommend this as it has issues and we wont get softwareupdates also.sometimes network signal will go suddenly and wifi range is pathetic
