Thank you for this. Interesting too, I can't imagine what the difference between "torch-light0" and "flashlight" is.

Can you do a ls- l on both of those directories please? On the other devices, the control file is world readable and writable. If it's obvious which one is which, you could try turning the torch on and off manually, e.g. to turn it on

Code:

echo 1 > /sys/class/leds/torch-light0/brightness

And to turn it off:

Code:

echo 0 > /sys/class/leds/torch-light0/brightness

I have some other changes to package, so if we can figure this out tonight I should be able to provide a working flashlight app pretty much straight away.
