With the device stream functionality, you can now view augmented reality experiences directly on a mobile device running Magic Leap Mobile App (MLA). Device streaming superimposes the digital content and audio over live video recorded from the world camera, and then streams that to your mobile device over your Wi-Fi local area network (LAN). You can use the device stream to view system menus, landscape apps, and immersive apps.
Limitations
While the device is streaming, the streaming icon in the upper-left of your view reminds you that you are streaming.
Keep these limitations in mind:
- Apps that require the world camera for image recognition and other purposes might not work correctly while the streaming service is using the world camera
- Video capture is not supported while streaming and device streaming is not supported while you are capturing video
- To protect privacy, some content such as notifications are not streamed
- To improve streaming performance while using Helio, use only one Helio window at a time
Streaming to a macOS or Windows PC
You can stream to your computer over your device's Wi-Fi network. Unless you have configured your device for Wi-Fi debugging, you need to connect a USB cable between your PC and your device to initiate the device stream, even though the stream itself is transported over Wi-Fi.
Prerequisites:
- USB-C cable
- Developer Mode enabled on Magic Leap device
- The Lab for macOS or Windows
- Connect the Magic Leap device over Wi-Fi to the same local network as your macOS or Windows PC
To enable device stream and stream to your PC:
- In the Magic Leap device, go to "Settings -> Device -> Developer", and then turn on "Enable Device Stream". If prompted to set up a Magic Leap Mobile App pairing, select "Later"
- In The Lab, install the "Device Stream" package and then launch it
- Connect the device to your computer through USB cable. The device stream program automatically detects the device
- On the device, select Accept at the New Connection Request notification prompt.
- The device stream should appear in the window
- Disconnect the USB-C cable
The device streaming app can configure your device for Wi-Fi debugging so that you can initiate new device streams without the USB cable.
To initiate a new device stream untethered:
- Initiate a device stream
- Click the triangle next to the device serial number
- Click and then click "Use Network"
- On the device, select "Accept" at the "New Connection Request" notification prompt
- Disconnect the USB-C cable
- Click the triangle next to the IP address
- Click next to the IP address, and then click "Remember"

Device Stream Guide
By default, the Device Stream Guide is displayed when starting device stream on the Magic Leap Mobile App.
To skip this screen when starting device stream, launch the Magic Leap Mobile App, go to the menu (☰ icon or swipe-right on Android) > Settings, and then turn off "Enable Device Stream Guide".
