Does it always seems like you never can find your remote control when you need it the most? Or that you have collected a clutter of remote controls and you can never find the right one?
One device that most people keep with them at all times is their smartphone and fortunately for products like the Roku 3, there are a lot of Apps available to install on your smartphone to remotely control the Roku. If you have an Android phone like the Micromax Canvas Knight2, you can go to Google Play to search for a Roku remote control application.
One of these applications is Romoku. Once you downloaded and installed Romoku, it will search for any Roku devices connected to the same WI-FI network as your Roku box.
After connection to your Roku, you can use Romoku to then control your Roku. Most of these applications only allow basic remote control functions but they should be good enough for most users. You can control Roku's own streaming channels as well as other streaming services like Amazon as shown here on a Samsung Smart LED TV.
