Notification flash not working

Problem solved. Getting the info straight from Apple is what did it. (It seems that I had not locked the phone on my previous tests of the flash.)

Thanks very much for your help!

The link you provided only goes to a page that says the page can't be found. Yes, the camera flash works, and the flashlight too.

I've been to a number of youtube videos showing how to turn the led on, but none of them help -- I can only assume that the procedure they give is the same as apple's, but if you can give me an effective link to what apple says, then I'll for sure read it.
