BYOM (Multi-Device
Collaboration with Phones)
Screen Projection
After a HarmonyOS device searches for and finds
a large screen and successfully connects to it, the
device can invoke the microphone, speaker, and
camera of the large screen as virtual peripherals.
1. Enable Wi-Fi on the large screen, and turn on
Wi-Fi and Bluetooth on your phone.
2. In the lower right corner of the large screen's
home screen, choose Settings > Smart
Functions and enable Multi-Device
Collaboration. (If the large screen runs
HarmonyOS 4.0, you also need to enable
Multi-screen Interaction for the large screen.)
3. Swipe down from the status bar of the mobile
phone to open the notification panel, enable
Wireless Projection, and search for and
connect to an available large screen.
4. On the status bar of Wireless Projection, you
can use the large screen's camera, speaker,
and camera via Switch audio/video.
Method
• Upon the first use of multi-device collaboration on
your device, obtain authorization from the large
screen and enter the device connection code.
• Audio and video switching can be performed only
on the phone.
• This function applies only to models that support
the Wi-Fi function.
