Camera Flash Doesn't Work topic

For no reason my camera flash sometimes doesn't work. When it doesn't work neither will other camera app flashes nor apps to use flash as a flashlight. A phone restart fixes it but by then of course the scene you wanted to photograph is gone.

I am stock VZW 4.4.4 never rooted in a month old Asurian replacement phone. I seldom use flash so I don't know how often this issue occurs. I never happened on my original note 3 however again I seldom used flash. Also I have read this happens to many other people but no measure to cure or prevent it other than the slow restart process.

Anybody know a real fix? Thanks!
