I disagree with this because my mics were working, done the upgrade to the latest software then they immediately stopped working. It's not as though the mic unsoldered itself whilst on the desk, is it? Let's face it, it instantly affeted thousands or millions of people at the same time.
The second the Samsung S6 Edge was released I ditched my Nokia Lumia 930 because it was terrible and Microsoft couldn't even get Skype to work (blank webcam, constant freezing or restarting, many missing features compared to Android...) on their own phone OS. If you go on many websites you see download for Android but not supported on Windows Phone. I think the term is white elephant
Good luck if you still use the 930.
