knocking or tapping on outgoing calls
I had an Android (Google Pixel) and experienced knocking and tapping sounds for over a year. T-Mobile store changed the SIM card. It didn't help. This went on for more than a year. Then I got an IPho...
I have the same issue and found the same apple support page and also just switched to T-Mobile and discovered the knocking when I made a call but it went away when they called me back... hopefully this ain't my new normal.
