Can’t Find Devices When Mirroring Your Phone? 5 Reasons and Corresponding Solutions

Reason 1: Inconsistent Network Environments

• Issue: The phone and display device are not connected to the same Wi-Fi network. This is the most common reason.
• Solution: Check the network connections of your phone and TV/mirroring adapter separately to ensure they are connected to the Wi-Fi of the same router.

Reason 2: Mirroring Function Disabled

• Issue: The wireless mirroring receiving function of the TV or projector is turned off.
• Solution: In the TV’s settings menu, find options like “Multi-Screen Interaction,” “Screen Mirroring,” “AirPlay,” or “Wireless Display” and confirm they are enabled.

Reason 3: Router Isolation Settings

• Issue: Some routers have “AP Isolation” or “Guest Mode” enabled, preventing devices on the same Wi-Fi from discovering each other.
• Solution: Log in to the router’s management backend, find the “AP Isolation” option in “Wireless Settings,” and disable it.

Reason 4: Device Restart or Cache Issues

• Issue: Long-term device operation causes software cache conflicts.
• Solution: A simple and effective method: restart your phone, TV, and router.

Reason 5: Device Compatibility Problems

• Issue: Older phones or TVs may not support newer mirroring protocols.
• Solution: Try using the mirroring function built into video apps (e.g., Tencent Video) (based on DLNA). For screen mirroring, consider purchasing an external mirroring adapter to expand the functionality of older devices.

Troubleshoot from easiest to most complex according to the above list, and 99% of “device not found” issues can be resolved. If the problem persists, try mirroring your computer to the same device—this helps you determine if the issue lies with the phone or the receiving device.
