Microphone issue during video calls on various apps when speaker mode is on
I am facing issue on various video calls apps eg facetime, messenger, viber, whatspp that voice is interrupted or muted on other end when speaker mode is on. Its new iphone 13 pro bought 3 weeks back running on ios 15.1.1 , the issue was there in previous ios version too. Problem is only during video calls and no issue during audio calls.
I tested hardware microphone using video, voice recording etc all seems ok. Not sure if its hw issue or ios issue? Has anyone experienced similar issue? What could be solution? Shall I exchange my phone assuming its hardware microphone issue or wait for next ios update assuming its ios bug? -Thanks.
