Samsung has released the Samsung TV Remote app for Android smartphones that only works with Samsung TVs. A version of the app is available for the Samsung Galaxy Tab as well as for Android smartphones. In addition to the standard TV remote features, the app provides a qwerty keyboard to input text on the TV. The Samsung TV Remote app is free and works with phones running Android 2.1 and newer.
Cable providers and TV manufacturers are smart to provide mobile apps for consumers. I enjoy using the Xfinity TV app on my iPad to see what is currently on TV, change TV channels, and I can even watch On Demand content. Comcast is developing an Android version of the Xfinity TV app that I am looking forward to installing on my phone.
Dish Users will find the free DISH Remote Access app useful. With it you can watch any TV channel that you subscribe to on your phone, control your DVR, search the program guide, and control your TV. Those who are lucky enough to have Verizon FiOS service can use the FiOS Mobile Remote app to control their TV as well as display pictures from the phone on the TV. Verizon provides a separate app for DVR control. Of course, if you ware one of the few people who own a Google TV, you can install the Google TV Remote app to control it from an Android phone.
