After the installation of the version iOS 13.5.1 few days ago, my microphone don’t work when I use app like whatsapp to call or videocall. In all the other way, it works properly. I tried to erase the app, change parameters and more.. but nothing works. My app is gb whatsapp Any help, please??
Go to settings > general > reset > reset Network settings , see if this helps
Iphone has 4 microphones 2 near charger port “for normal “ 1 near front camera “for free hand call/loudspeaker/video call/video recording using front camera” your problem is related to this so you need to change front camera 1 near back camera “for video recording using back camera”
