MTP is not particularly useful. If it must be used, it seems to be more stable in Windows Explorer. Otherwise, using another protocol might be a better solution. For example, using some ADB GUI tools.
With mtp_enable = false, the phone storage is not even accessible, Internal Storage folder doesn't open. (I did Exit Dopus after changing the preference.)
So, would have to use Windows File Explorer to work on portable devices ig.
Since Windows File Explorer works for me, I would prefer that, FTP is too much trouble for slower speeds.
I did try with two different wires and on both the ports, same issue. As I pointed out earlier, the issue is .nomedia files (in the folders mentioned above) getting created automatically instantly after deletion. That auto creation happens even when deleting using Files app or third party explorers on the device.
Thanks for trying to help.
Since it's a Samsung device, and they are messy with standards, I think best option for me is just use Windows File Explorer when I have to deal with such folders.
