Mic stopped working

I got the amber update for my Lumia 720 and it was working fine for a day. Suddenly the mic stops working. I did not realize it until I found that there is no audio for the videos shot. Did multiple soft resets and the problem persisted. After much googling, found a reply to a suggestion in this link:

Hello guys! To solve headset and microphone issues after upgrading to WP 8, just deactivate all TTY/TDD features from Accessibility options in settings menu.

Enabled the TTY to full and the mic started working (check immediately by voice command - long press windows key) Disabled the TTY and the mic still works. Glad that it was only a software issue.


Update: The issue worsened over time and the above solution did not work many times. Took it to the service center and they replaced the mic/USB unit under warranty.

Brilliant ! Absolutely no way to watch what I want! (XBOX Music & Videos)

I downloaded some videos from MSDN Channel9 site and copied to my phone. These have long file names and this is how I see it in the Music & Videos App (XBOX).  The screen or the file names doesn't scroll right!. How am I supposed to view what I want? Tried to get a landscape view but the view is locked. I am utterly disappointed with this serious lack of some basic functionality. Totally surprised and disgusted, especially knowing that this thing is from Microsoft, the 'gurus' in UI and functionality. Lack of testing? or Lack of commitment?
