I can’t hear myself when I record on the front camera or the back at all, Siri doesn’t detect any sound and neither does the voice message feature, I can not hear music when I plug in my headphones and when I call the person on the other end can not hear anything. Well that’s how it was at first, now the call will just fail and when I click the voice message icon it just closes immediately. But I can play music out loud and get notifications and others videos. WHAT THE HECK
