Using a USB Cable

Connecting your Android phone to a mini projector using a USB cable is one of the most straightforward methods. This approach is ideal for projectors that allow direct data transfer from your phone.

Detailed Steps:

  1. Locate the USB port on your mini projector. It’s often marked with the USB symbol.
  2. Take your Android phone’s USB cable (typically a Micro USB or USB-C cable) and plug one end into your phone.
  3. Insert the other end of the cable into the USB port on your projector.
  4. Set your projector to USB mode. You can typically do this by pressing the ‘Source’ button on your projector or remote until you see the USB option.
  5. On your Android phone, a notification might appear asking what you want to do with the USB connection. Select ‘File Transfer’ (or similar option).
  6. The projector should then display your phone’s screen. If not, you may need to select the correct file or media you want to display through the projector’s menu.


This method is simple and doesn’t require a Wi-Fi connection. However, it may not work with all projectors and could limit the use of your phone while connected.

Wireless Connection via Wi-Fi Direct

Wi-Fi Direct is a wireless standard that enables devices to connect directly to each other without needing a Wi-Fi network.

Detailed Steps:

  1. Check if your mini projector supports Wi-Fi Direct and turn it on. You can typically find this option in the settings menu under the Wi-Fi or network section.
  2. On your Android phone, go to Settings > Wi-Fi.
  3. Tap on the three dots or ‘More’ option and select ‘Wi-Fi Direct.’ Your phone will start searching for devices.
  4. Select your projector from the list of available devices. You might need to accept a prompt on the projector to establish the connection.
  5. Once connected, you can use apps that support Wi-Fi Direct to project your content.


Wi-Fi Direct is a convenient wireless connection option that doesn’t rely on a separate network. However, it may not be supported by all mini projectors and might have a steeper learning curve for new users.

Using Bluetooth

If your projector supports Bluetooth, you can use it for a wireless and convenient connection, though it’s more common for transmitting audio rather than video.

Detailed Steps:

  1. Turn on Bluetooth on your mini projector, usually available in the settings menu.
  2. Enable Bluetooth on your Android phone by going to Settings > Connected devices > Bluetooth.
  3. On your phone, look for your projector in the list of available devices and tap on it to pair.
  4. If prompted, confirm the pairing code on both your phone and projector.
  5. Once connected, you can use the projector with apps that support Bluetooth projection.


Bluetooth connections are wireless and convenient for audio. However, they are less common for video and might require compatible apps or additional setup.

HDMI Connection

Many mini projectors come equipped with HDMI ports that offer a reliable and high-quality connection for video and audio.

Detailed Steps:

  1. Purchase an HDMI cable and an adapter for your Android phone if it doesn’t have a dedicated HDMI port (Micro USB to HDMI or USB-C to HDMI).
  2. Connect the HDMI end to your projector and the appropriate end to your phone’s adapter.
  3. Plug the adapter into your phone.
  4. Switch the input on your projector to the HDMI port you’re using.
  5. Your phone’s screen should now be mirrored on the projector.


HDMI connections provide excellent video and audio quality and are widely compatible. However, they require you to be tethered to the projector and might need additional adapters.

Screencast with Miracast

Miracast technology allows you to wirelessly mirror your Android phone’s screen to your projector if both devices support Miracast.

Detailed Steps:

  1. Ensure both your Android phone and the mini projector support Miracast. This can usually be checked in the device’s specifications or settings.
  2. Enable Miracast on your projector. This option may be located in the input or network settings.
  3. On your phone, go to Settings > Display > Cast (the precise pathway might differ depending on your Android version).
  4. Tap on the three-dot menu and select ‘Enable wireless display’ if not already enabled.
  5. Select your projector from the list of available devices.
  6. Follow any prompts to complete connection setup. Your phone’s screen should now be visible through the projector.


Miracast allows for wireless screen mirroring but requires compatible devices. It may not support some apps due to rights restrictions (like streaming services).

Google Home App

The Google Home app can help you connect your phone to a mini projector if it has built-in Chromecast or is connected to a Chromecast device.

Detailed Steps:

  1. Make sure your projector has Chromecast functionality or is connected to a Chromecast device, and that it’s on the same Wi-Fi network as your phone.
  2. Download the Google Home app on your Android phone.
  3. Open the app and follow the setup instructions to add your Chromecast or projector to the app.
  4. Once your devices are connected, tap on your device in the app and select ‘Cast my screen’ at the bottom.
  5. Follow the prompts to begin casting your phone’s screen to your projector.


Using the Google Home app is a user-friendly way to send your phone’s display to your projector, assuming you have Chromecast or a connected device. It’s wire-free but relies on a stable Wi-Fi connection.

Third-party Apps

Many third-party apps are designed to facilitate connections between Android devices and projectors, like EZCast or AllCast.

Detailed Steps:

  1. Install a third-party app compatible with your mini projector.
  2. Connect both your phone and projector to the same Wi-Fi network.
  3. Open the app on your phone and follow the instructions to detect and connect to your projector.
  4. Once connected, use the app’s interface to select and project your media.


Third-party apps offer alternative connection methods and may support a variety of file types. However, they may introduce compatibility issues and require a bit of trial and error to find the right app.
