USB massive storage not recognized in Galaxy S20, Android 11.
The built-in file explorer shows files in USB.
But in android api such as android.provider.MediaStore.getExternalVolumeNames(Context), the mount path not found. (It shows Primary and sdcard path. )
In Android 11 below, it works fine.
I think it is compatibility issue.
Please let me know how to list up files and open files in USB(OTG).
