One of the more unique features of the Samsung Galaxy S4 is the inferred sensor at the top. The built in Watchon app and IR sensor makes the S4 a pretty useful universal remote. You can set up individual rooms. The code base is pretty extensive. The app had no trouble finding the code for a very old Viewsonic TV in my bedroom. The app also makes recommendations for you based on what you like. It also can show you HD channels only.
