Use It as a Remote Control and Stream Sports, TV Shows, and Movies to Your Television
With live TV streaming services such as Sling TV, you can watch over one hundred live channels both on your old Android phone and on your living room TV. Just connect your TV to a Chromecast device or the Fire TV and use your smartphone as a remote control.
If you own a smartphone with an infrared emitter, you may also want to try one of many available universal remote apps available on Play Store. For example, AnyMote Universal Remote+ is compatible with over 900,000 devices, making it possible to replace all remote controls in your home with a single Android smartphone.
