Why does the LED notifications rarely work? I know about the Light Flow app but I have been reading it is screwing up some phones. I know my LED is not broken as I have seen it flash once or twice(and tried the led tester app and it lights up every single color I tried). I dont care about the timing (which is slow), I care about missing a text from an hour ago because the light never went off in the first place. This has got to be a software bug right? I read somewhere that samsung phones have problems with LEDs.
