stops working after looking at "Settings"

[mozai]

• Device: Samsung SM-G730W8
• Operating system: Android 4.4.2
• Application Version: 2.7

Expected behavior

Always change the icon and toggle LED light when tapping the button.

Actual behavior

Changes icon but LED light does not turn on.

How to reproduce

1. Open app
2. Click button, observe button changing and LED light turning on/off
3. Click hamburger menu button (upper-left)
4. Click Settings, then '<-' back.
5. Click button, observe button changing and LED does not turn on/off

Workaround

• go to Android task manager, 'End' the Torchlight app. It will work as expected next time it is started
• never ever use the hamburger menu in the upper-left

@mozai I'm currently busy with #13 and I expect it's fixed when I'm done with that.
