Describe the bug
We have an urgent issue with a Solar2d App when used by our uses on Samsung Device. I have narrowed down the issue to this command: -

display.save( displayedPhoto, { filename="img1.jpg", baseDir=system.TemporaryDirectory, isFullResolution=false, backgroundColor={0, 0, 0, 0} } )

The crash happens when the display.save is called against any display group.

I have tried to recreate the crash on Android Studio with the same OS but it does not crash.

Device Details are: -

Model Name: Galaxy Tab A
Model Number: SM-T510

Android Version 11
Kernel Version: 4.4.177

I have modified your Solar2d Camera App to include the above save line which also creates the crash. I enclose the project.

I have also include the crash report from the device.
