About your complaint, my Vivo V5 works fine. I tried playing music in background, then I could receive WhatsApp
immediately with the sound and sd Card has Problem music sound together work. For volume sound, and only 155 mb Capa City thougn it actwauy capable of 8 gig when formet it on Vivo my smartphone works fine too, if I clicked checklist Ascending rintone, the volume ringing will play from low to loud when people call me, if the Ascending ringtone switch off, it will play the standard volume that I set on my smartphone. If I set loud, it will play loud when people call my smartphone and vice versa.
I have been using Vivo V5 for 4 months.
