Android TV not casting from phone — Wi-Fi, Google Cast, app and device issues
Technician
• Brand/model of the TV or box (Sony Bravia Android TV, TCL, Hisense, Philips, Xiaomi Mi Box, Nvidia Shield, Chromecast with Google TV, etc.)?
• Are you using built-in Chromecast / Google Cast, the Google Home app screen mirroring, or a specific app (YouTube, Netflix, Disney+, Spotify, etc.)?
• Phone type: Android (Samsung, Pixel, Xiaomi, etc.) or iPhone?
• What exactly happens: TV doesn’t appear in the cast device list, cast icon is missing, stuck on “connecting”, black screen, or video plays on the phone only?
• Is the Android TV on Wi-Fi or Ethernet, and is your phone on the same Wi-Fi network (same router, not a guest network)?
The more detail we have, the better we can fix an Android TV not casting from phone instead of just rebooting things randomly.
Technician
A few things usually break casting:
• The TV and phone are on different subnets or guest networks (even if it’s the same router name).
• Router features like AP isolation / client isolation block devices from seeing each other.
• The Google Cast receiver service on the TV is frozen after an update or long uptime.
• Out-of-date Android TV firmware, Google Play services, or casting apps on the phone.
We’ll:
1) Confirm the Android TV and phone really share the same network and can discover each other.
2) Restart the casting stack on both the TV and phone (not just a quick TV power tap).
3) Check Chromecast built-in / Google Cast settings on the Android TV and the router’s isolation / guest options.
That almost always fixes an Android TV not casting from phone or stuck on “connecting”.
Technician
Step 1 — Make sure phone and Android TV are on the same LAN
1) On the TV, go to Settings ▸ Network & Internet → confirm it shows your main network and not “Guest” or a separate VLAN.
2) On the phone, open Wi-Fi details for your network and note the IP (for example 192.168.1.50).
3) On the TV, check its IP in Network status. Ideally, the first three numbers match (e.g. 192.168.1.x). If the TV is 192.168.0.x and the phone is 192.168.1.x, they’re on different subnets and casting to Android TV will fail until that’s fixed.
Step 2 — Turn off isolation and restart router
• In the router interface, temporarily disable guest Wi-Fi, “AP/client isolation”, “wireless isolation”, or “block LAN to WLAN”.
• Reboot the router after changing settings (full restart, not just Wi-Fi toggle).
Once the network lets devices see each other, we’ll refresh Chromecast built-in on the TV.
Technician
Step 3 — Hard-restart Android TV and Chromecast built-in
1) On the TV go to Settings ▸ Apps ▸ See all apps ▸ Show system apps (wording varies).
2) Find Chromecast built-in or Google Cast Receiver → choose Force stop, then Clear cache (not data).
3) On some Sony / Google TV models you can also Uninstall updates and let it auto-update again — this often fixes casting issues after a system update.
4) Fully power-cycle the TV: unplug it from the wall for 60 seconds, then plug back in and turn it on.
Step 4 — Refresh casting on the phone
• On your Android phone, update Google Home, Google Play services, YouTube/Netflix in the Play Store.
• Clear cache for one test app (YouTube ▸ Storage ▸ Clear cache).
• Turn Wi-Fi off/on and close all recent apps.
Now try casting from YouTube again and see if the Android TV appears in the cast list more quickly.
Technician
Step 5 — Optimise Wi-Fi and streaming path
• If possible, keep the Android TV on wired Ethernet (that’s ideal) and your phone on a strong Wi-Fi signal — preferably the same band (both on 5 GHz) and close to the router.
• Avoid VPN, ad-blocking DNS apps, or “data saver” modes on the phone; these often break casting from phone to Android TV.
• In the router settings, disable QoS rules that throttle streaming apps and turn off “AP isolation” on the Wi-Fi band used by the phone.
Step 6 — Test with a known good app & lower quality
• From the phone, open YouTube, tap the cast icon, pick the TV, and play a short 1080p video.
• If it stutters, drop the quality to 720p in YouTube and check whether the cast stabilises.
• If YouTube is solid but Netflix/Disney+ still misbehave, we’ll clear those apps’ cache and sign-in tokens next; sometimes it’s app-specific casting issues.
Technician
Try this on the TV (names vary a bit by brand):
• Go to Settings ▸ Apps ▸ See all apps ▸ Chromecast built-in and make sure it isn’t disabled or restricted.
• Under Settings ▸ Apps ▸ Special app access, check any item about “Display over other apps” or “System services” related to casting and ensure they’re allowed.
• On Sony/Philips models, look under Settings ▸ Network & Internet ▸ Remote start / IP control / Home network and enable options that allow the TV to be powered on via network (helps reliability for casting to Android TV in standby).
• For iPhones, make sure AirPlay / HomeKit or “Apple AirPlay & HomeKit” is turned on in TV settings; then use the AirPlay icon in supported apps or iOS Screen Mirroring rather than Google Cast.
Once these are on, more apps and both Android and iPhone should see the TV as a cast target.
Technician
Preventive setup for Android TV casting
• Keep a single, stable home network name (SSID) and avoid changing it — otherwise apps may lose access to previously paired TVs.
• Leave the Android TV on Ethernet if possible, and keep your main casting phones on the same router (not repeaters with isolation turned on).
• Disable overly aggressive router features like “Guest mode for all Wi-Fi”, heavy parental controls that block local traffic, or AP isolation.
• When you see Android TV firmware updates, install them, then reboot the TV and test casting with a simple app like YouTube right away.
• Periodically restart the TV (or schedule a weekly auto-restart) so the Google Cast receiver doesn’t get bogged down after weeks of uptime.
These small steps make casting from Android or iPhone to Android TV far more reliable.
Technician
• Make sure you’re signed into the same account in the app on your phone and (if it has one) on the TV.
• Update that specific app to the latest version; some services only expose the cast button in newer builds.
• On Android phones, clear cache and then force stop the problem app. On iPhone, delete/reinstall it.
• Check the service’s help page to confirm they support casting to Android TV / Chromecast; a few niche apps don’t support Google Cast at all.
If even Google’s own apps (YouTube, Google TV, etc.) refuse to cast after you’ve done all the network and TV steps, we may look at resetting Android TV network settings or, as a last resort, a factory reset of the TV. We can walk you through that live in chat so you don’t lose more than necessary.

Quick answer: the accepted fix
Accepted fix when Android TV won’t cast from phone: make sure the Android TV and phone are on the same home network (no guest Wi-Fi or VPN), then reboot the router, TV and phone. On the TV, force stop and clear cache for Chromecast built-in, ensure casting/AirPlay are enabled, and update Android TV firmware. On the phone, update Google Home and streaming apps, clear their cache, then try casting again from YouTube as a test.
Why Android TV stops casting from your phone
Most Android TV casting problems come down to three things: network isolation, a frozen Google Cast receiver on the TV, or outdated firmware/apps. Router updates can put phones on a guest SSID or enable AP isolation, blocking discovery so the Android TV doesn’t appear in the cast list. Long uptimes or buggy updates can cause Chromecast built-in to crash on the TV, so apps stay stuck on “connecting”. And if your Android phone or iPhone uses an old app build, VPN, or battery/data saver mode, casting or screen mirroring to Android TV may fail even when Wi-Fi looks fine.
How to test if casting to Android TV is really fixed
After making changes, leave the Android TV and router on for a while and perform a few tests. First, open YouTube or Netflix on your phone, check that the cast icon appears, and confirm that the TV shows up instantly in the device list. Start a 1080p video and see if it plays smoothly on the TV without your phone screen staying active. Then try casting from another app (like Spotify or a local video via Google Photos) and, if you have one, from a second device such as an iPhone. If multiple apps and devices can cast reliably to the Android TV with no “can’t connect” messages, your Android TV casting setup is in good shape.
Android TV won’t cast from phone — quick troubleshooting tips
Most cases are fixed by aligning networks and refreshing Chromecast built-in and your apps.
Quick path: verify your Android TV and phone are on the same network (no guest Wi-Fi, no VPN), then reboot the router, TV and phone. On Android TV, force stop and clear the cache for Chromecast built-in / Google Cast, make sure casting or AirPlay is enabled, and install pending system updates. On your phone, update Google Home and streaming apps, clear their cache, and test using YouTube’s cast button. If only one app fails to cast, update or reinstall that app — some services require the latest version before they show the cast icon.

FAQ
Why won’t my Android TV cast from my phone even though Wi-Fi works?
Even if the internet works, casting to Android TV needs your phone and TV on the same local network with no isolation. Guest Wi-Fi, AP/client isolation, VPNs, or a frozen Chromecast built-in app on the TV can stop discovery so the TV never appears in the cast list or gets stuck on “connecting”. Rebooting the router, TV and Chromecast built-in usually restores casting.
Does my phone have to be on the same Wi-Fi as Android TV to cast?
Yes. For Google Cast and most Android TV casting features, your phone must be on the same home network as the TV. That means the same router (and normally the same subnet), not a separate guest SSID, corporate Wi-Fi, or mobile hotspot. If they’re separated, your phone often can’t discover the TV and the cast icon will show “no devices found”.
How do I fix Android TV not showing up in the cast list?
First, connect the phone and Android TV to the same network and turn off VPNs or guest Wi-Fi. Then reboot the router and TV, force stop and clear the cache for Chromecast built-in on the TV, and update the Google Home app and streaming apps on your phone. In many cases this makes the Android TV appear instantly in the cast device list again.
When should I reset Chromecast built-in or Android TV for casting issues?
If multiple apps can’t cast, the TV doesn’t appear on any phone, or casting breaks again right after every reboot, you may need to reset the Chromecast built-in app (clear data/uninstall updates) or, as a last resort, perform a factory reset of Android TV after backing up your logins. This refreshes the casting stack when normal restarts aren’t enough.
