Hii friends, the vivo v9 youth is very good phone.but the main issue is with video calling as its not having volte feature for network, i am not able to use jio to jio direct video calls.and camera quality is not so good.firstly it has battery backup problem.and it has slow motion video recording feature, not a waterproof mobile.overall excellent mobile with superb finishing.but I am not satisfied with vivo v9 youth.
