Ubuntu – Android phone keeps remounting itself

I have a problem when copying pictures and videos from my android phone, the android phone keeps remounting itself and because of that the copying process halts and I can't copy the files that I want to copy.

I use Ubuntu 14.04 LTS (kernel version: 4.2.0), I had other problems with other phones when copying files like some files not copying. I am also wondering if I upgrade to a newer kernel or just update the whole distro to a newer version (which would also update the kernel version), will problems with the MTP mounting and stuff like this be fixed? Do you know any temporary fix I can do so the phone doesn't automatically remount itself every time when I try to copy somehting?
