Have you followed the instructions of selecting Voice Isolation during phone calls? Messenger is a Meta (Facebook) product and does not support Voice Isolation.


Please review the step by step instructions for enabling Voice Isolation in the Apple Support article shared below.

You need to have Apple perform diagnostics on your iPhone. It can be done in person at an Apple Retail Store or at an Apple Authorized Service Provider. You can also contact Apple Support and request remote diagnostics.


If you’re in the US please call  1-800-MY-APPLE or outside the US, consult the support articles below.
