    Its not after any software update but my 720's mic suddenly stopped working. It works perfectly on voice recording and other similar apps but the issue is only when making calls. Is this some kind of a hardware issue? How do I get this rectified?

    If it was a hardware issue it wouldn't work at all.

    You can try a soft reset to see if that helps at all.

    Soft reset - volume down + power button until phone vibrates. Phone restarts. No data deleted.
