Turning Off Other People's TVs Instead of having to pair your GS4 with other devices, The Off Button works by sending out universal IR power codes (367 to be exact) while you point your device towards the television you'd like to shut off. Cycling through 367 codes will take roughly seven minutes, though most functional codes will be between 1-100. After cycling to the correct code and having the television turn off, press the large power button again to stop sending signals (otherwise it will turn the TV back on). Note: You won't be able to kill every single TV in a bar or pub at once, since you have to point your IR blaster at each TV individually, but it could be a relatively quick process if the TV models are all the same. See the next section to speed things up.

Saving Power Codes Cycling through numerous codes can be annoying when you already know the one that works, so cut that time out completely. If there's a television you want to regularly shut off, like at a local bar or your workplace, then take note of the code between 1 and 367 that turns it off, then go to the Saved Codes tab. In here, you can save various codes for use at another time. Tap on a slot, label your code (i.g. "Dad's room"), then simply input the code that shut that specific television off. You will now be able to automatically shut off the television without cycling through countless codes. Convenient, right?

Wreaking True Havoc Want to get some great laughs while out with friends? Then spend some extra time with The Off Button when out at a sports bar or something. Attempt to save as many codes of televisions in your vicinity, then use check the Send Continuously at the bottom of the My Codes page. This will definitely get your bartender annoyed (or thinking about the supernatural).

And It Could Get Even Better It's a minimal app with some major amusement, and will turn you into the TV terror you always wanted to be. One improvement that I would like to see is to have the app ask if I would like to save a code as soon as it works. This would make it a little easier on users, though it's not a huge deal.
