The blinking red LED on BlackBerry 10 is iconic. It's been there forever and it's something that we love our BlackBerry for. You always know when there is a notification thanks to the little red light blinking. At times I find myself plugging away at work and the LED will constantly be blowing up. Rather than having to unlock my device and head into the Hub to dismiss the notification, I've found you can simply tap the standby button on top of the device and it kills the LED. The notifications will still be there, but you can go about your business with no LED until you get a chance to check them out. Cool, huh?
