I found the setting, and something interesting as well:
Settings > Accessibility > Flash notification
When I came into the settings it was already unchecked, yet my phone was exhibiting behavior as if it was. I had to check the setting and exit the menus. Then I went back in to uncheck the setting and exited the menus again. This time the setting ...
S3 users have reported similar issue while receiving calls and alarm going off at AndroidCentral forums here.
The solution posted there is to go to Settings > My Device > Accessibility > Hearing > Flash Notification
Un-check Flash Notification.
Even if the flash notification box is not checked, check it once and un-check it again. It should ...
Was annoying, but has stopped, by doing the following:
Go to: Settings > My Device > Accessibility> Hearing> Flash notification
Select flash, close out, return and deselect flash.
Working properly now!
This question was asked over at StackOverflow HERE
Basically, the answer is No. The OS is limited to pretty much just FLASH_ON and FLASH_OFF. Though I have seen some flashlight/torch apps that have a 'turbo' mode that makes the LED even brighter (but that's not what you want and these types of apps usually require ROOT access).
Another workaround is to ...
As a Nexus 7 owner, I can confirm for you that it does not have a LED flash for its front-facing camera. In fact, off the top of my head, I can't think of a single device that does.
Documentation of a feature that isn't present is going to be hard to come by. A good verification of this fact, however, is in ifixit's teardown pictures (see steps 12 and 13). ...
I don't know how to detect a Volume Up/Down button press for 'n' seconds, so I would give an alternate solution. You would have to install Xposed Additions Pro and TeslaLED Flashlight. The former needs root access and Xposed Framework installed.
Visit my answer here. Under the heading "Instructions for Xposed Additions" follow steps 1-6.
u need to flash the rom named Karatep. the one you flashed in for k6 power.
K6 Note (Karatep)
Here is a workaround you could use.
Create a Task to toggle torch ( alternatively get a TeslaLED plugin -it supports a lot of devices).
I am not sure if this is my device limitation but the Hardware state is only limited to media button and not power button but nevertheless I believe the outcome will be the same.

Both of those functions consume a large amount of energy. The phone's processor and other components require a minimum amount of energy to remain stable. The battery can only output so much at a time. The phone is not letting you use both simultaneously time to avoid a "brown-out" and potential crash or other failure (perhaps it is unsafe for the battery as ...
Theres a Torch app in the market that toggles on open.
Do you want a single button on home screen? Then you need to shortcut it.
Do you need it on your lock screen: swipe for widgets.
Do you need it on voice activation? "Ok google, open app flashlight/torch"
Do you want it on your shortcut bar? Drag it from programs.
Im not really sure what you want.
