Well, I'm french, I just did the update for the 14.3 IOS and since I did that, like many many people around, I got two troubles :
1 - when i make a call, the sound is like the person I'm calling is on Mars ! I have to push my ear on the phone to hear it a little. When I put the speaker no problem.
2 - I can't use siri anymore. When i say "hey siri" it doesn't recognize my voice anymore. BUT when i start siri manually, he can understand without any problem my voice. By the way when i record a sound in a message the sound is very low to and many noice like it's a message from Mars again. On the video too.
As a phone is made to phone, it's a little annoying no ? I can make a call with the speaker but well it's not the point.
All is working fine for youtube, etc... Bluetooth too. I read and try like most of you all those settings tips around but helpless.
It was working fine and just after the update it wasn't. And it's not a setting problem, not a phone problem, it's an IOS firmware problem and it's a shame that apple didn't do anything since many months.
So any way to have my phone back ?
PS : I even try to delete all settings and data and start a new phone. Same thing.
PS 2 : i called Apple in France, they don't know the problem yet... Incredible.
