Bug description

On crDroid 12 (Android 16), QQ crashes and automatically restarts immediately after a QR code scan result is successfully recognized and displayed.

The scan itself works correctly, but when QQ attempts to enter the QR login/auth confirmation page, the entire QQ process dies and is restarted by the system.

This issue is reproducible consistently.

Steps to reproduce

Step 1. Open QQ
Step 2. Open the built-in QR scanner
Step 3. Scan any QR code
Step 4. Wait until the scan result is recognized and displayed
Step 5. QQ immediately crashes and restarts automatically

Solution

Unknown at the moment.

Possibly related to QR login/auth activity handling or WebView interaction on Android 16.

Additional context

• The QR code is recognized successfully before the crash occurs.
• The crash seems to happen specifically when QQ transitions to the QR login authorization page.
• Issue reproduced multiple times.
• Other basic QQ functions appear normal.

Acknowledgements

• I've checked device is officially supported and that no support is provided for unofficial devices (for device specific reports and not source related).
• I'm running latest version available on crdroid.net for this device and that the device is still maintainer supported (not flagged unsupported on download page)
• I have searched the existing issues and this is a new and no duplicate or related to another open issue.
