Android TV not casting from phone — Wi-Fi, Chromecast built-in, app and router issues
Technician
• Exact Android TV brand/model (Sony, TCL, Hisense, Philips, Xiaomi, Nvidia Shield, etc.)?
• Are you using the cast icon from an app (YouTube, Netflix, Prime Video, etc.) or screen mirroring from the phone settings?
• What type of phone: Android (Samsung, Pixel, Xiaomi…) or iPhone?
• What do you see when you try to cast: TV not listed, “no devices found”, stuck on “connecting”, black screen, or “something went wrong”?
The more detail we have, the easier it is to fix Android TV not casting from phone without you factory-resetting everything for nothing.
Technician
Common causes when an Android TV won’t cast from phone:
• Phone and TV end up on different Wi-Fi bands or networks (main vs guest, 2.4 GHz vs 5 GHz, separate router/extender).
• The TV’s Chromecast built-in / Google Cast service has glitched after an update or after the TV waking from standby.
• Router features like AP isolation / client isolation or “guest mode” block devices from discovering each other.
• Corrupted app cache on the phone (YouTube, Netflix, Google Play services) causing casting stuck on “connecting”.
We’ll:
1) Make sure the phone and Android TV are truly on the same network and able to talk to each other.
2) Restart and refresh Chromecast built-in on the TV.
3) Clean up problematic apps and services on the phone so casting to Android TV becomes instant again.
Technician
Step 1 — Confirm phone and Android TV are really on the same network
1) On the Android TV go to Settings > Network & Internet and check the network name (SSID) and IP address.
2) On the phone, open Wi-Fi settings and make sure it’s connected to that exact same SSID.
3) If your router has both 2.4 GHz and 5 GHz with the same name, that’s fine — Google Cast works across bands — but we want to avoid:
• “Guest” or “IoT” networks for either device.
• Separate mesh nodes that use client isolation or “AP isolation”.
4) In your router’s Wi-Fi settings, turn OFF “AP isolation / client isolation” or “Wireless isolation” on the SSID where the TV and phone connect.
Step 2 — Simple connectivity test
• On the Android TV, open the YouTube app.
• On the phone, open YouTube, tap the cast icon, and see if “Link with TV code” is offered.
• If the TV never appears in the device list, we know discovery is being blocked and will adjust router/TV settings next.
Technician
Step 3 — Fully restart Android TV and Chromecast built-in
1) On the TV, go to Settings > System > Restart (or long-press the power button and choose “Restart”). Avoid just turning the TV off/on with the remote.
2) After it reboots, go to Settings > Apps > See all apps.
3) Find Chromecast built-in (or “Google Cast”), then choose:
• Force stop
• Clear cache (do not erase data yet)
4) Do the same “Force stop + clear cache” for:
• Google Play services
• Google TV / “Android TV Home” if present
Step 4 — Re-test casting from the phone
• On your phone, also reboot once, then open YouTube and tap the cast icon.
• Pick the TV when it shows, wait up to 20–30 seconds for the Android TV casting handshake to finish.
If this fixes YouTube but other apps still don’t cast, we’ll clean those specific apps next.
Technician
Step 5 — Fix casting issues in a specific app (Netflix example)
On the phone:
1) Open Settings > Apps > Netflix (or the app that won’t cast).
2) Tap Storage & cache → Clear cache, then Clear storage/data.
3) Make sure Google Play services and the Google Home app are updated in the Play Store.
On the Android TV:
4) Open the Play Store and update Netflix (or affected app) and any pending system app updates.
5) Confirm the TV’s Date & time are correct and set to your region; wrong time can cause secure stream/cast failures.
6) Launch Netflix on the TV once and sign in fully so the TV is registered as a valid playback device.
Then try again: open Netflix on your phone, tap the cast icon, choose your Android TV, and start a video. This usually fixes “Android TV can’t connect to this device” errors for premium apps.
Technician
• Android TV uses Google Cast / Chromecast built-in, not native AirPlay (unless your TV specifically advertises AirPlay support).
• From an iPhone, you cast using the cast icon inside supported apps (YouTube, Netflix, Disney+, etc.), not via Control Center’s screen mirroring button.
To make Android TV show up on iPhone:
1) Make sure iPhone and Android TV are on the same Wi-Fi and not on a guest network.
2) Open a Chromecast-enabled app like YouTube on the iPhone — you should see the cast icon at the top.
3) If no devices appear, reinstall the Google Home app on iPhone and set it up so it discovers the Android TV on the network.
4) If the TV still doesn’t appear, we’ll double-check that Chromecast built-in is enabled on the TV and that router isolation isn’t blocking cross-platform casting.
Once that’s done, casting from both Android and iOS phones to your Android TV should be consistent.

Preventive setup for Android TV casting
• Keep your Android TV on the main home Wi-Fi, not guest or isolated networks; avoid “AP isolation” on that SSID.
• Name your main Wi-Fi clearly (e.g.
Home_Main) and connect both TV and phones only there.• Allow the TV to install system and app updates, but once a month reboot it fully via Settings > Restart to clear stale Cast sessions.
• Keep the Google Home app and major streaming apps updated on your phone; outdated apps are a common cause of Android TV cast not working.
• If you change router, SSID or password, update Wi-Fi on the TV first, then relaunch casting apps on the phones so they rediscover the TV cleanly.
These small habits make it much less likely that “Android TV won’t cast from phone” shows up again out of nowhere.
Technician
Step 6 — Deep checks before factory reset
• Confirm Wi-Fi or Ethernet is connected on the TV and that apps on the TV can stream normally.
• In Settings > Apps > Chromecast built-in, clear cache and storage, then reboot the TV.
• In Settings > System > About, install any pending system/firmware updates for the Android TV.
• On the router, briefly disable guest Wi-Fi and any “Block LAN to WLAN” style options, then test casting again.
Step 7 — Last resort: reset casting or the TV
• Some brands include a “Reset Chromecast built-in” or “Reset Google Cast” option in the TV’s apps menu — try that first.
• If nothing helps and the TV still never appears as a cast target, a full factory data reset of the Android TV often brings casting back — but you’ll need to sign into apps again.
We can walk through those exact menus for your TV brand live in chat so you don’t lose more settings than necessary.

Quick answer: the accepted fix
Accepted fix when Android TV won’t cast from phone: make sure the phone and TV are on the same main Wi-Fi network (not guest or isolated), then restart the router, Android TV (via Settings > Restart) and the phone. On the TV, force stop and clear cache for Chromecast built-in and update system apps. Finally, clear cache/data for the casting app on your phone and try again. In most cases this makes your Android TV appear in the cast list and connect without errors.
Why Android TV suddenly stops casting from your phone
Most Android TV casting problems come down to network discovery or a stuck Cast service. Router updates can change Wi-Fi isolation or guest settings, so even though both devices see the internet they can’t see each other. Android TV firmware or app updates can also glitch Chromecast built-in / Google Cast, leaving your phone stuck on “connecting” or showing “no devices found”. Corrupted cache in apps like YouTube, Netflix or Google Play services is another frequent reason why an Android phone can’t cast to Android TV until those apps are reset.
How to test if Android TV casting is really fixed
After each change, use a simple test: open YouTube on your phone, tap the cast icon, and choose your Android TV. If the TV appears quickly, connects, and starts playing within a few seconds, Google Cast discovery and connection are working. Try a second app like Netflix or Disney+ to confirm it’s not app-specific. If video plays fine but casting drops after standby or overnight, your Android TV or router power-saving features may be putting network and Cast services to sleep too aggressively, so disabling deep sleep or scheduled power-saving on the TV can help keep casting stable.
Android TV won’t cast — quick troubleshooting tips
Most cases are fixed by cleaning up Wi-Fi, restarting Android TV properly, and resetting Chromecast built-in.
Quick path: make sure your Android TV and phone are on the same main Wi-Fi, not guest network. Restart the router and Android TV from the Settings menu, then force stop and clear cache for Chromecast built-in and Google Play services on the TV. On the phone, clear cache/data for the app you’re casting from and update the Google Home app. If your Android TV is still not showing up as a cast device, check the router for AP isolation and, as a last resort, reset Chromecast built-in or perform a factory reset of the TV.

FAQ
Why won’t my Android TV show up when I try to cast from my phone?
This usually means the phone and Android TV aren’t seeing each other on the network. Make sure both are on the same non-guest Wi-Fi, turn off AP/client isolation on the router, and restart the TV via Settings > System > Restart. Then clear cache for Chromecast built-in on the TV and try casting again.
Do my phone and Android TV have to be on the same Wi-Fi to cast?
Yes. For Google Cast / Chromecast built-in, your phone and Android TV must be on the same local network. Using different SSIDs, guest networks, VPNs, or mobile data can prevent the cast icon from finding your TV or cause “no devices found” errors.
How do I fix Android TV stuck on “connecting” when casting?
First restart your router, Android TV (from Settings) and phone. Then on the TV, force stop and clear cache for Chromecast built-in and Google Play services. On the phone, clear cache/data for the app you cast from and update the Google Home app. This typically fixes Android TV stuck on connecting during casting.
When should I reset Chromecast built-in or factory-reset my Android TV?
Reset Chromecast built-in if your TV never appears as a cast target, even after restarts and cache clears. Only factory-reset Android TV if casting still doesn’t work for any app or phone and you’ve ruled out router issues — a reset will sign you out of apps and remove custom settings.
