For many years, we've had to live with the fact that our smartphones and tablets don't always have an LED (Light-Emitting Diode) panel on the front side. The reason for this is simple: the manufacturers are just too smart and clever, and they've figured out a way to put the LED panel on the backside of the device. And that is exactly what they have done, and it's not a mistake, because this way, they can make more money.

The problem is that, for us, this means that we can't use our smartphones and tablets as our main mode of communication. And that is really sad, because the whole point of having a smartphone or a tablet is to be able to use it as a tool for communicating with the outside world.
