Most interactions we have with our phones happen via the display screen. If it becomes unresponsive, you are in trouble, although a simple reboot could fix the problem.

It gets even worse for those with broken screens that render the devices almost unusable, making it nearly impossible to perform even the basic of tasks like turning off the phone via the power menu on the screen.
