I used this answer, I have played with it but for my life I just can't get it working quickly. I can turn the flash on and off easily with a button, no issue, code works well.

But every time I turn the light on there is a delay and makes for a kind of slow app. I have seen torch apps which are pretty instant.

Any help?

Me too!
Trying to get this delay away for a week

Has anyone come across a way around the delay issue? I'm trying to take a picture with a single flash (not double) and when I press the button it takes a good 3 seconds before the flash goes on!

Sorry for reviving this old post but can someone tell me what to put in the header file for this?
