If your phone mirroring or “Multi-Control” fails to connect:
Check Samsung Account:
Ensure both the Galaxy XR and your smartphone are signed into the exact same Samsung Account.
Toggle UWB & Bluetooth:
Turn Bluetooth and Ultra-Wideband (UWB) off and back on via the Quick Panel on both devices.
Wi-Fi Synchronization:
Both devices must be on the same Wi-Fi network (preferably the 6GHz band of a Wi-Fi 7 or 6E router) for features like Wireless DeX to function.
Reset Connections:
Go to Settings > General Management > Reset > Reset Network Settings to clear any corrupted handshake protocols.
