Hi, I actually buy the new iphone 7 Plus, i have a problem with whatsapp video, when i touch and hold camera button to video, i got twice shutter camera sound so my video always recorded shutter sound. Do you guys have any issue like me? i want to know it is whatsapp problem or my device. I've already uninstall WA and install again but not worked. I've already restore my iPhone with itunes but not worked. NB: Other apps like Instagram, Line Messenger, BBM = No problem (I assume maybe they use default iOS camera). Other Problems again, I can't muted my Camera Shutter Sound too. Thanks anyway!
