You can always use Uvh which should update. When I played with it, I first
removed the older libmpt libraries.  U is for update, but it didn't in my
case, saying a library supplied by the older version was required by vlc.

If there is nothing to be updated, Uvh will just install.  At any rate,

I'm not sure what happened.  As I think I said, I removed the older version
first.

One point that I've found on more recent distributions is make sure the
phone is unlocked when plugging it in.

I use a window manager with fewer features (dwm) so I didn't see any icon.
On distributions that I do use to access the phone, on one of them, Lubuntu
with LXDE, it will show up and be accessible in the file browser.  On the
others, I run the command simple-mtpfs (or variant, depending upon
distribution) to mount it.  However, I wasn't able to successfully install
any of those (simple-mtpfs, mtpfs, or jmtpfs) on CentOS.

Honestly, I don't know.  However, I'm no expert programmer (or packager, I
just ran rpmbuild -ba on the spec file to build it.)
