After having gotten my LED issues more or less worked out on GPA10, I updated to 11 and am now having issues again, albeit a different one. I wiped data and cache and reinstalled GPA11, and the issue persists.
The LED will flash when I receive a notification, and turn off when the screen is on as expected with a stock build, but when the screen turns off again the LED does not start flashing again. This is a little frustrating for me. I've tested it and it happens with every type of notification, be it email, SMS, whatever. All of my apps are stock and I am using the default kernel.
