First of all I would like to say thanks to wolke for such a good app! I found it very useful and practical. There is one thing that bothers me. If you activate the led/torch in lowpower screen and after releasing, there's a little "snap" sound from the device. It doesn't sound good. Think it could be harmful in the long run for the LED? Edit: I just found out that you can hear the same sound after closing camera app (after photo taken) and also from closing a flashlight app. Wonder why...
