Turn Android Phone Into Chromecast: Full Guide

This guide shows you how to turn an Android phone or tablet into a Chromecast receiver, letting other devices cast videos, music, and screen mirrors to it. You’ll need an Android device running Android 6.0 or newer, a stable Wi-Fi network, and a casting app from the Google Play Store. No root required.

What You’ll Need

• An Android phone or tablet (Android 6.0 or later) that will act as the receiver.
• A second device (phone, tablet, or computer) to cast from — this can be another Android, an iPhone, or a Chrome browser.
• Both devices must be on the same Wi-Fi network.
• A casting receiver app installed on the Android device. Popular options include AirScreen, Cast Receiver, or AllCast Receiver — all free on the Play Store.

Step-by-Step

1. Install a casting receiver app. Open the Google Play Store on the Android device you want to use as the receiver. Search for “Cast Receiver” or “AirScreen” and install one. These apps make your device appear as a Chromecast-compatible device on the network.
2. Connect both devices to the same Wi-Fi. Go to Settings > Wi-Fi on both devices and ensure they are on the same network. If you have a dual-band router, make sure both are on the same band (2.4GHz or 5GHz) — some casting apps have trouble across bands.
3. Open the receiver app. Launch the app you installed. It will typically show a welcome screen with the device name and a status like “Ready to Cast.” Some apps ask for permissions (nearby devices, notifications) — grant them so the app can run in the background.
4. Keep the receiver screen on (or adjust settings). For the first test, keep the screen on. Many receiver apps have a setting to keep the screen awake or run in the background. If you want to use the device for other tasks, enable the “keep awake” or “background mode” option in the app’s settings.
5. Start casting from your source device. On the device you want to cast from, open a casting-supported app like YouTube, Netflix, or Google Chrome. Tap the Cast icon (a rectangle with a Wi-Fi-like symbol in the corner). A list of available devices appears — your Android receiver should show up with the name you set (often the device model or a custom name from the app).
6. Select your Android device. Tap its name. The casting will begin. The receiver app will show a live preview of what’s being cast, and the source device will show “Casting to [device name].”
7. Control playback. You can play, pause, seek, and adjust volume from the casting device. The receiver app may also show playback controls, but the source device is the primary controller.
8. Stop casting. Tap the Cast icon again on the source device and select “Disconnect” or “Stop Casting.” The receiver app will return to its idle screen.

Common Mistakes

• Devices on different Wi-Fi networks or bands. This is the most common issue. Even if they’re on the same router, a 2.4GHz and a 5GHz network are separate networks. Use the same SSID for both.
• Receiver app not running in the background. Many apps close when you switch to another app or the screen sleeps. Check the app’s settings for “background mode” or “keep awake.”
• Firewall or router isolation. Some routers have “AP isolation” or “client isolation” enabled, which blocks device-to-device communication. Disable this in your router settings.
• Using a VPN on either device. A VPN can interfere with local network discovery. Turn it off temporarily.
• Battery optimization killing the app. Android’s battery saver may stop the receiver app. Go to Settings > Battery > Battery optimization, find the app, and set it to “Don’t optimize.”

Tips

• Set a custom device name. In the receiver app’s settings, you can change the name that appears on other devices. Use something recognizable like “Living Room TV” or “Bedroom Display.”
• Use a wired connection for the receiver. If your phone supports Ethernet (via USB adapter), a wired connection improves stability and reduces lag.
• Keep the receiver plugged in. Casting drains battery quickly. Keep the device charging while in use.
• For screen mirroring, use the source’s native cast. On Android, use Google Home’s “Cast screen” feature. On Windows, use Chrome’s “Cast” menu. The receiver app handles both.
• Update the receiver app regularly. Developers frequently fix compatibility issues with new Android versions and casting protocols.

Troubleshooting

• Device not showing up in the cast list. Check that both devices are on the same Wi-Fi. Restart the receiver app and the source app. If still not visible, try restarting your router.
• Connection drops after a few seconds. This often indicates a weak Wi-Fi signal. Move the receiver closer to the router. Also, disable any power-saving features on the receiver that might throttle the network.
• Audio plays but video is black. This can happen with DRM-protected content (like some streaming services). The receiver app may not support HDCP. Try a different app or use a screen mirror instead.
• Cast works but there’s noticeable lag. Reduce the casting resolution in the receiver app settings (e.g., from 1080p to 720p). Also, close other apps on the receiver to free up CPU.
• Receiver app keeps crashing. Clear the app’s cache (Settings > Apps > [App] > Storage > Clear Cache). If that fails, uninstall and reinstall the app. Make sure your Android OS is updated.

Frequently Asked Questions

Is this exactly like a real Chromecast?

Functionally, yes for most apps. The receiver app mimics the Chromecast protocol, so apps like YouTube, Netflix, and Spotify will see it as a Chromecast. However, some advanced features like Google Cast’s guest mode or certain DRM-protected content may not work.

Can I use my phone as a Chromecast while using other apps?

Yes, if the receiver app supports background mode. Many apps allow you to run the receiver in the background, but the phone’s performance may be affected. For best results, dedicate the device to casting.

Does this work with iPhone or Windows?

Yes. Any device that supports Chromecast (iPhone, iPad, Windows with Chrome, etc.) can cast to your Android receiver as long as they’re on the same network.

Will casting work without internet?

No, you need an internet connection for most streaming services. However, local casting (e.g., casting a video from your phone’s storage) may work over a local network without internet, but the receiver app still needs a Wi-Fi network to communicate.

Is there a difference between free and paid receiver apps?

Free apps usually have ads and may limit resolution or session duration. Paid versions often remove ads, add higher resolution support, and provide better stability. For occasional use, free apps are fine.

Can I cast to my Android from another Android?

Yes, absolutely. Both devices just need to be on the same Wi-Fi. Use the Cast icon in apps like YouTube or use Google Home’s “Cast screen” feature.
