Just like the HTC One, the Samsung Galaxy S 4 features an IR blaster along with a companion app to see what's on TV and get recommendations. Samsung's version is called WatchON and doesn't appear to be as robust as HTC TV, but it gets the job done. WatchON lets you control your TV as well as a cable or satellite box through the IR blaster at the top of Galaxy S 4. You will need to go through an initial setup, but soon after, you will be able see your TV guide on your GS4 and get recommendations based on your interests. Just tap on a show or sporting event to get more information and once more to change the channel to that particular program. We put together this hands on video showing you how to set it up as well as some of the features from the WatchON app. Skip on past the break to see how it works, and don't forget to check out our other Galaxy S 4 guides.

Can i connect my ps3 to this app
Works great but I can only use it on one tv. Which kinda sucks. I have 5 tvs but only can control 1
You can add more TV’s. You have to select the option to add another room. You can only program one TV per room.

Search google play for “IR Universal Remote” by wavespark. Its a free Infrared universal remote application that lets you control your tv and other devices like your xbox360.
keep going with the app as you CAN have AV receivers and a lot of other devices.
I’ve set up my TV, bluray player, AV receiver, Apple TV, WDTV, but I cant get my Strong settop box to work. :(
My app, which clicking on Show, try to change TV Channel rather then DirecTV box channel. Don’t know how to setup correctly.
