@nathaneltitane Storage properties are clarified in https://wiki.termux.com/wiki/Internal_and_external_storage. You can have full access only to internal and shared storage.

Only applications using Storage Access Framework APIs are able to write to external storage. Termux command line tools, like bash or coreutils, are not using Android APIs and in general not part of Android OS runtime. They are executed by Linux kernel and are subject for restrictions implied by DAC (chmod/chown) and MAC (SELinux).
