Samsung Galaxy S4 TV Remote Control Feature. How it works?

Samsung galaxy S4 TV remote control is the one of the best things that i have found. The already installed app WatchOn controls this feature. I got my Samsung Galaxy S4 a month ago and yesterday i discovered this feature. I didn't read Samsung galaxy S4 reviews before, therefore i didn't know about it.

Two days ago i heard about this somewhere on YouTube and installed a remote control app from Google play store. That wasn't working well. So i lost hope that this feature is not very good. But yester when i was browsing different apps. I came across "WatchOn" app. I opened it and i saw a remote control like window. I selected TV, then i selected TV make. after that the app asked me to use the power off feature. I used it and then the app asked me whether your TV turned off/on. I said yes because the Off/On button was working. Once WatchON saved my TV setting I used all the buttons all features were working. Volume up/down, channel up/down and numbers, mute, A/V button all were working extremely well. That was a surprise, even my TV remote control isn't so perfect.

The range is excellent. I tried the remote control feature from 20 feet distance and it was working like a charm. This app is perfect you won't need a remote control if you have this app.

Then i read online about remote control feature of Samsung Galaxy S4 and i came to know that Samsung has pre-installed remote controls of more than 350 brands. Isn't this awesome? ? ?
