Lumia 1520 No one can hear me on calls without speaker

[WPCentral Question]

So I upgraded my Lumia 1520 to Windows 8.1. Now when I call anyone they say it sounds like I'm a mile away and most people can't hear me. On speaker it works fine and there's no issue. Any advice?

Try a soft reset as a first rule and go from there

I did a soft and hard reset. Still not working.
