Connecting a smartphone to Android TV opens up a lot of possibilities: from broadcasting videos and games on the big screen to controlling the TV as a remote control. But not everyone knows that there are several connection methods, and each is suitable for different tasks. For example, wireless screen transfer via Miracast or Google Cast is ideal for watching movies, and USB debugging will be needed by developers or those who want to deeply customize the system.

In this article we will analyze all the current connection methods - from simple (via Wi-Fi Direct) to advanced (using ADB). You will learn which method to choose for your TV model (Sony Bravia, Xiaomi Mi TV, Nvidia Shield etc.), how to avoid common mistakes (for example, screen freezing or no sound), and what applications will simplify the process. And if you encounter a problem, at the end of the article there is FAQ with solutions for typical failures.

1. Connection via Google Cast (Chromecast built-in)

The most popular method is using technology Google Cast, which is built into most Android TVdevices (for example, Sony KD-55X80J or TCL 6-Series). It allows you to broadcast content from your phone to your TV screen wirelessly, while maintaining control from your mobile device.

To use Google Cast, follow these steps:

  • 📱 Open an application on your phone that supports broadcasting (for example, YouTube, Netflix or Google Photos).
  • 🔍 Find the icon "Broadcast"** (usually in the upper right corner) and select your Android TV from the list.
  • 🖥️ Confirm the connection on the TV, if necessary.
  • 🎬 Start playing content - it will automatically appear on the big screen.

This method also works for screen mirroring (full image transfer from the phone), but with reservations: some models (for example Xiaomi Mi Box S) require turning on options Enable wireless display in settings Android TV (Settings → Devices → Wireless display).

💡

If the broadcast icon does not appear, check whether the phone and TV are connected to one Wi-Fi network. Some applications (for example, Disney+) block the broadcast due to DRM restrictions.

⚠️ Attention: On TVs with Android TV 12+ (for example, Google TV Chromecast 2023), additional confirmation via Google Account. If a code appears on the TV screen, enter it on your phone in the browser using the link cast.google.com.

2. Wireless mirroring via Miracast (Wi-Fi Direct)

Miracast is a wireless screen transfer standard that does not require an Internet connection. It is useful if you do not have a router or want to stream content on the go (for example, from a phone to a portable Android TV box). However, not all TVs support Miracast out of the box - on some models (Philips 7000 Series) this function must be enabled manually.

Connection instructions:

  1. On the TV, go to Settings → Networks and Internet → Wi-Fi Direct (or Wireless display).
  2. Activate the mode "Waiting for connection"**.
  3. On phone, open Settings → Connected devices → Wireless display (on Samsung — Smart View, on Xiaomi — Wireless Display).
  4. Select your TV from the list and confirm the connection.

If the image is on TV slows down or breaks, try:

  • 📶 Reduce the distance between devices (optimally - up to 3 meters).
  • 🔄 Reboot both devices.
  • 🔧 In the phone settings, select mode Performance instead of Battery saving.
Why Miracast may not work on some TVs?

On devices with Android TV 9.0 and lower, sometimes there is no support Miracast due to manufacturer restrictions. Also, the problem may be in the firmware - check for updates in Settings → System → Software update.

Connection method Requires Wi-Fi Supports audio Latency (ms) Suitable for games
Google Cast Yes Yes 100–300 No (lag)
Miracast No Yes 50–150 Conditionally (depending on the model)
USB debugging No No 0 Yes (for emulators)
HDMI (MHL) No Yes 0 Yes

3. USB connection (ADB and MTP)

If you need not just to broadcast the screen, but control the TV from your phone (for example, for debugging or installing applications), use USB connection with USB debuggingenabled. This method is suitable for Android TV boxes (Nvidia Shield, Xiaomi Mi Boxand some TVs (Sony with a port USB Type-C).

Step-by-step guide:

Enable developer mode on Android TV (Settings → About TV → Click 7 times on the build number)

Activate USB debugging (Settings → Developer preferences → USB debugging)

Install on the phone ADB drivers (for example, via Minimal ADB and Fastboot)

Connect the phone to the TV with a cable USB-A → USB-C (or adapter)

-->

After connecting, check the connection with the command:

adb devices

If your serial number appears in the response Android TV, the connection is now established:

  • 📁 Transfer files via adb push /path/to/file /sdcard/.
  • 🎮 Control your TV from your phone (for example, via Scrcpy).
  • 🔧 Install APK: adb install app.apk.
⚠️ Attention: On some TVs (LG with WebOS or Samsung Tizen) USB debugging is not available —this method only works on pure Android TV.

4. Connection via HDMI (MHL or USB-C)

For minimal latency (important for gaming or watching videos in high definition) use wired connection via HDMI. There are two options:

  1. MHL (Mobile High-Definition Link) - for old phones with a port Micro-USB.
  2. USB-C → HDMI - for modern smartphones (for example, Samsung Galaxy S22, Google Pixel 7).

What you will need:

  • 🔌 Adapter USB-C → HDMI (for example, Anker 810 or original from Samsung).
  • 📺 Cable HDMI 2.0 (for support 4K@60Hz).
  • ⚡ Source power supply for the phone (the port USB-C on the adapter usually does not charge the device).

How to connect:

  1. Connect the phone to the adapter, and the adapter to the port HDMI on the TV.
  2. On the TV, select the appropriate source signal (HDMI 1/2/3).
  3. If the image does not appear, turn on Image transmission via HDMI (to Samsung — DeX).
💡

A wired connection via HDMI provides zero latency and supports resolutions up to 4K HDR, but requires compatible adapter. Not all phones support audio output via HDMI - check the specifications of the model.

5. Controlling Android TV from your phone as a remote control

If you do not need screen broadcasting, but only TV control (switching channels, launching applications), use the official application Android TV Remote Control from Google or an alternative like Yatse.

How to set up:

  1. Install the application on your phone Android TV Remote Control from Google Play.
  2. Connect your phone and TV to the same Wi-Fi network.
  3. Launch the application and select your TV from the list.
  4. Confirm pairing on screen Android TV.

Advantages of this method:

  • 🎛️ Complete replacement of the remote control with a touch keyboard.
  • 🔍 Voice search through the phone microphone.
  • 📱 Quick access to installed applications.
⚠️ Attention: On TVs with Android TV 10+ application Android TV Remote Control may require firmware update to work correctly. If the buttons do not respond, check the software version in Settings → System → Update.
