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 recently switched to T-Mobile and hear this knocking sound every time I call a specific friend. I used to call this same friend for many years with AT&T and the same phone, and never had the issue.
DEFINITELY a T-Mobile network issue and they should own up to it
