Smart TVs have evolved with features like AirPlay and voice control, but the remote remains essential. Using your phone as a remote is convenient since you always carry it and it's easier to misplace a physical remote. Typing on a phone's keyboard is far easier than using an on-screen keyboard with a TV remote.

Some modern Android phones include built-in IR blasters with universal remote apps preinstalled. Launch the app, add your TV manufacturer, and test buttons to confirm correct infrared commands. This method can even turn your TV on and off, though IR hardware is rare on mainstream phones from Samsung, Google, or Apple.

Most smart TV platforms offer official companion apps. Google TV and Android TV users can use the Google TV app on both Android and iOS, requiring the same Wi-Fi network and Bluetooth enabled. Roku and Fire TV have their own mobile apps with familiar D-pad controls and QWERTY keyboards for easier text entry. Apple TV users can add the Remote app to Control Center without installing anything extra.

Third-party universal remote apps like TV Remote Control (500,000+ downloads, 4.6 stars) work across brands via Wi-Fi or infrared. You're not limited to manufacturer apps—choose whichever interface you prefer.
