using Terminal Emulator I created a file;
cd /storage/emulated/0/Downloaded echo test > test.txt
Then using Android File Transfer I can see files in the same dir but not the test file.
ls -l indicated it's not a chown chmod issue;
-rw-rw---- root sdcard_r 3323 2016-02-22 15:15 other.txt -rw-rw---- root sdcard_r 5 2016-02-22 15:15 test.txt
sync, repluging, killing the client, and changing to PTP then back to MTP did not help but a reboot did so what's up with that?
