You're trying to find the remote control, but it's nowhere to be seen. It could be down in the cushions, or maybe one of the kids made off with it. Whatever the reason, it's annoying, and you wish you had a better solution. Depending on the phone you own, that better solution may be in your pocket right this moment: a smartphone with an integrated IR blaster, enabling you to control your TV and select other devices with the same device you're always carrying around. If your current phone doesn't have a built-in blaster, though, you're not without some options.
