GoKawiilGuide details methods to control any smart TV using a smartphone
Smart TVs still rely on remote controls, and many now support using a smartphone as a substitute via built-in IR blasters or app-based connectivity. Certain Android phones have infrared hardware and pre-installed universal remote apps that let users pair with their TV brand and control power, volume, and navigation. Devices from Apple, Samsung, and Google lack this IR hardware, but alternative software-based remote options exist for those users.
