Why does the Three.js AR demo show a 'plane-detection' unsupported error on my device?

Based on the error message you're encountering, it appears that your device or the WebXR Extension you're using doesn't support the 'plane-detection' feature that the Three.js AR plane detection example requires.

The error "The required feature 'plane-detection' is not supported" indicates that while your device can run WebXR content, it doesn't have the capability to detect and track real-world planes in your environment, which is necessary for this specific demo.

Here are some suggestions to address this issue:

1. Device Compatibility: Not all devices support all WebXR features. The Samsung A22 might not have the necessary hardware or software support for plane detection in AR.

2. WebXR Extension Limitations: The WebXR Extension you're using might be providing basic WebXR functionality but not the advanced feature of plane detection.

3. Try a Different Demo: You could try other Three.js WebXR examples that don't require plane detection, such as basic AR examples.

4. Use ARCore-supported Device: If possible, try using a device that explicitly supports ARCore (Google's AR platform), as these typically have better support for features like plane detection.

5. Check Browser Compatibility: Make sure you're using a browser that fully supports WebXR features. Chrome is generally recommended for WebXR content.

Unfortunately, if your device or the WebXR Extension doesn't support plane detection, you won't be able to run this specific example without changing to a device that supports this feature.
