The way we connect with each other has changed dramatically over the past couple of decades. Early mobile phones had just one function: to facilitate voice calls. Today? Many of us would rather text someone than call them. Yet, when it comes to keeping track of these modern communications, we don’t have that many options. You can choose between a loud chime or an easily-missed vibration alert, and that’s it. But it wasn’t always this way.
I am, of course, talking about the humble notification LED — once present on all manner of phones, smart and dumb. Unfortunately, you’ll be hard-pressed to find a mainstream smartphone with one today.
