Hi, I've only had this happen once. A full DFU is not required at all, and if anyone claims that it is necessary, they're wrong. A simple restart will bring things back to normal. If you haptic feedback on, then it is easier than with it off. While haptic feedback is on, press the down volume and the side button in for a few seconds until you feel the haptic feedback. This has brought up the shutdown dialog. Be careful here, as you could accidentally call emergency services if you have that feature enabled. What you do is to flick left until the haptic feedback feels like you're hitting the left wall. When you're at this point, you are on the "Power Down" button, so double-tap and your iPhone will turn itself off. Wait about a minute between double-tapping to shutdown, and holding the side button to turn the iPhone back on. Once it restarts fully, VO will be working normally again.
If VO is off, then flicking left will not result in the haptic feedback hitting the left wall. So, you'd then need to press the side button three times to turn VO on, then follow the steps above to turn the iPhone off and back on. I haven't totally figured out what the trigger is that causes this to happen, but I believe it has something to do with the screen going to sleep while on the call. If it's a shorter call where the screen does not put itself to sleep, then this does not usually happen. At least in my situation, that's been the case. Later...

Also, was using the Find Me, the phone was there, and it was even saying that it was ringing, after I requested it. Again, no sound! How to report such a problem to Apple? Sometimes I feel like at the call centre thy are trying more to say that it is normal than trying to understand the issue. Also, they will ask for a full restore with DFU mode… I can see this happening… Às 21:06 de 05/10/2019, Loy Green escreveu: > I experienced this once my self.
