Whenever the notification LED activates, it acts weird. It'll be fine for a few seconds but then it says on for a little too long (maybe a second), then flashes brighter than normal after that and turns off, and flickers back on a after another second or less. It does this in random patterns. It used to be fine, just flashing normally in a steady pattern. I can't figure out if it's a hardware or software issue. I've restored the phone to factory settings and still the same thing. Just got it 2 weeks ago and only noticed it today. I uninstalled a lot of recent apps I installed as well but the problem persists. Anybody have an idea?
