Screen mirroring on the OnePlus 15 is meant to make sharing your screen quick and seamless, whether you are casting videos, photos, or presentations. When it fails to connect or suddenly stops working, it can feel confusing and inconvenient. In most cases, the problem is caused by connection settings, compatibility issues, or minor system glitches that are easy to fix.
Why Screen Mirroring Is Not Working on Your OnePlus 15
- The phone and TV are not connected to the same Wi-Fi network.
- Screen casting permissions or features are turned off.
- The receiving device does not fully support Miracast or wireless display.
- Temporary system glitches are preventing the connection.
- Software issues after a recent update.
1. Make Sure Both Devices Are on the Same Wi-Fi Network
Screen mirroring relies on a shared local network to detect nearby devices. If your phone and TV are connected to different Wi-Fi networks, they will not see each other at all.
Open Settings, and then tap Wi-Fi.
Connect your OnePlus 15 to the same Wi-Fi network used by your TV or streaming device.
Once connected, try screen mirroring again.
2. Turn Screen Cast Off and Back On
The screen cast feature can sometimes stop responding in the background. Turning it off and back on refreshes the connection and forces the phone to rescan nearby devices.
Open Settings, and then tap Bluetooth and device connection.
Tap Cast, and then turn Screen Cast off.
Wait a few seconds, turn it back on, and check if your TV appears.
3. Restart Your OnePlus 15
A restart clears temporary system processes that may be blocking screen mirroring. This simple step often fixes issues caused by background glitches.
Press and hold the Power button until the power menu appears.
Tap Restart, and then wait for the phone to boot up fully.
Try screen mirroring again after the restart.
4. Restart the TV or Casting Device
The issue may not be with your phone at all. TVs and streaming devices can also freeze or stop responding to casting requests.
Turn off your TV or streaming device completely.
Unplug it from power for about thirty seconds, and then turn it back on.
Once it is fully loaded, try connecting your OnePlus 15 again.
5. Check Compatibility with Your TV
Not all TVs support Android screen mirroring the same way. Some require Miracast support, while others rely on Chromecast or proprietary casting systems.
Check your TV settings and look for Screen Mirroring, Miracast, or Wireless Display.
If your TV does not support these features, consider using a Chromecast or compatible adapter.
After confirming compatibility, retry the connection.
6. Update Your Phone Software
Outdated software can cause casting features to stop working properly. Updates often include fixes for wireless display and connectivity issues.
Open Settings, and then tap About device.
Tap Software update, and then check for updates.
Install any available update and test screen mirroring again.
Screen mirroring problems on the OnePlus 15 are usually temporary and easy to resolve. Once both devices are properly connected and refreshed, casting your screen should work smoothly again.
