Yes, for example: ‘C-x C-f /sdcard/ RET’

It's this one:
directory-files-and-attributes("/sdcard/" nil nil t string)
I also tried what happens in ‘M-x shell‘ and for example ‘cat’ does the
same:
$ cat /sdcard/existent-file
cat: /sdcard/existent-file: Permission denied
$ cat /sdcard/non-existent-file
cat: /sdcard/non-existent-file: No such file or directory
This at least verifies that /sdcard points to the right location.
The same happens in Termux if and only if I remove the given storage
permission from it. But in Emacs, it happens whether the permission is
given or not.
