I cannot copy files to my Android MTP files or my pen drives

Question

I plug in my pen-drive and it copies a few files before nemo freezes and shuts down. And the data remains partially copied. I have been looking around for stuff on AskUbuntu. Using this, I figured out the mount point was

/run/user/$UID/gvfs

I tried this link from another AskUbuntu answer.

I tried this

umount /var/run/user/$UID/gvfs

umount: /var/run/user/0/gvfs: no mount point specified.

Tried this from this)

sudo chmod 777 -R /var/run/user/$UID/gvfs/*

Nor did the accepted answer Considering the device name if GT P5100

Answer 1

So, I have been using Nemo as a file explorer and it doesn't seem to work when I use Nemo. When I switched to Nautilus temporarily, the files transferred sucessfully.
