iPhone 7plus calls not working properly
Using the phone app or other apps like Facebook messenger, the call either immediately drops and says call failed, or the speaker is heavily distorted or replaced with loud static.
I’ve tried soft and hard resets, updating my iOS, restoring my iPhone, and resetting the settings. I haven't downloaded anything in quite awhile for this to suddenly happen and my phone hasn’t been near water or anything so I’m not sure what could have caused this issue.
Any suggestions or troubleshooting tips would be greatly appreciated.
