Shortly after the update to Kit Kat 4.4.2, my droid started displaying a red and white blinking notification LED (red on the outside, white in the middle). The Motorola KB for LEDs just says that other app providers might display their own combinations of LED colors for notifications. Anyone else getting this color combination? Should I be concerned? I've gotten very nervous about about my phone lately since the periodic hanging started, presumably caused by Kit Kat (reviewing other forums about that).
