I can't find the same device as the one you provided (Samsung S2x Android 13). I found a Samsung S23 Android 14 but couldn't reproduce your problem. I remember that the Android native SDK fixed a problem with the video frame uStride/vStride error in the onCaptureVideoFrame callback. I'm not sure if it is related to this but I think you can try to upgrade to 6.3.1 to see if it works or not.

The issue has been resolved after upgrading to the latest package version. It is likely due to updates in the Android native SDK. The app is now working fine on Samsung Galaxy S20, S21, and S22. We are closing this ticket
