How to cast your phone to a TV

A step-by-step guide, then cast to TV apps. Methods depend on your phone and TV brand; check the TV’s settings and manual.
Check what your TV supports
Many smart TVs and streaming sticks support casting or mirroring from phones, but which standards depend on the brand. Look in the TV’s settings or manual for casting or screen mirroring.
Cast from inside apps
Put phone and TV on the same Wi-Fi network, open a video app and tap the cast icon. The TV then streams the video itself, so your phone stays free and uses less battery.
Mirror the whole screen
For photos, games or apps without a cast button, use screen mirroring from your phone’s quick settings or control centre. Turn on do not disturb first so notifications do not appear on the TV.
When it does not work
Restart both devices, check they are on the same network, update the TV, and move closer to the router. If Wi-Fi is the problem, a cable adapter is the reliable fallback. Compare apps in cast to TV apps; for a remote on your phone, see TV remote apps.
