You can enter mobile phone settings-multi-screen interaction-turn on multi-screen interaction, and the mobile phone will automatically search for devices that support WLAN display (some models do not support voice synchronization).
The use of multi-screen interactive function requires the connected devices to support WLAN display function, and the mobile phone and the connected devices use the same WiFi network for scanning connection.
The specific steps are as follows (taking vivo Y85 as an example):
1. Find the setting icon on the mobile phone desktop and enter the setting interface.
2, enter the settings to find multi-screen interaction.
3. Open "Multi-screen Interaction" in Multi-screen Interaction and scan the connection.
