Asus, Android 8, no problem.
Samsung, Android 12, yes problem.

Anyway, in your code,

                            (tramp-shell-quote-argument localname)))
             ;; We insert also filename/. and filename/.., because "ls" doesn't.
             ;; Looks like it does include them in toybox, since Android 6.
             (unless (re-search-backward "\\.$" nil t)
               (narrow-to-region (point-max) (point-max))


$ adb shell ls -a /sdcard/|fgrep .
.face

Anyway, so on this samsung with android 12, you get /sdcard/.. etc. but
you don't rewrite them back to .. etc.
