*Note:

  2. Not the whole going blank, the button is still there. However, the preview before taking picture/video became black screen

Walter,
Are you able to easily recover from the 'blank screen'?  Or must you kill camera, and start again?

[Walter Chen[:ypwalter][:wachen]]

Hi, 
    I am unable to recover it from the blank screen with 3 button. 3 buttons would be there. You can switch to gallery, but if you switch back the camera won't recover from its original status. Also, if you trigger the button to take the shot, the button would grey out. And, switching between camera or video doesn't work any more.
    You must kill camera and start again.

I've been digging through this since last week; looks like under some conditions, the camera driver exhausts its shared memory and doesn't recover.  Investigation is continuing.

umm...It's strange to mark backward since this one opened earlier.
And, this one is one for otoro.

I marked this one a dupe because the other bug has more detailed information, and I strongly suspect these are related.  I'm happy to leave them separated too.
