A misplaced TV remote does not necessarily mean buying a replacement. An old Android phone or tablet can work as a TV remote for free, as long as the television supports mobile control. Most smart TVs can be controlled through an app, as long as the phone and TV are connected to the same Wi-Fi network.
How to use an Android phone as a TV remote
The most common method is to connect the Android phone and TV to the same Wi-Fi network and then pair them through a compatible remote app. Once connected, the phone can be used to change channels, adjust the volume, and navigate the TV interface. These apps vary by device and may display advertisements. Some TVs and remote apps support Bluetooth instead of Wi-Fi. Bluetooth lets the phone connect directly to the TV, though compatibility depends on the television and the app being used. Unlike Wi-Fi or Bluetooth, an IR blaster does not require the phone and TV to be connected to the same network. It sends commands directly to the TV’s infrared receiver, similar to a conventional remote.
The Wi-Fi and Bluetooth methods can be used without buying additional hardware when the TV and phone support them. An IR blaster, meanwhile, requires a separate accessory but can be useful when wireless TV control is unavailable.
