#+title: MTP on Linux: Mount Your Phone Without a File Manager
#+description: Mounting Android phones on Fedora Linux with jmtpfs.
#+slug: mtp-linux
#+filetags: :linux:
I recently ran into trouble attempting to mount my GrapheneOS phone to my laptop
running Fedora Linux via the [[https://en.wikipedia.org/wiki/Media_transfer_protocol][Media Transfer Protocol]] (MTP) and discovered a
simple and effective solution.
* Use a Universal Serial Bus (USB) 3.0 Port
First, ensure that the device was plugged in to the laptop through a USB 3.0
port, if possible. From a brief glance online, it seems that USB 2.0 ports may
cause issues with dropped connections over MTP. This is purely anecdotal since I
don't have any evidence to link showing that USB 2.0 causes issues, but I can
confirm that switching to a USB 3.0 port seemed to cut out most of my issues.
* Switch USB Preferences to MTP
Secondly, you need to ensure that the phone's USB preferences/mode is changed to
MTP or File Transfer once the phone is plugged in. Other modes will not allow
you to access the phone's file system.
* Install =jmtpfs=
Next, I used the =jmtpfs= package to mount my phone to my laptop. There are
other packages that exist, but this one worked perfectly for me. On Fedora
Linux, you can install it like this:
#+begin_src sh
sudo dnf install jmtpfs -y
#+end_src
* Create a Mount Point
Once you have the package installed, you just need to create a folder for the
device to use as a mount point. In my case, I used =/mnt/pixel=:
#+begin_src sh
sudo mkdir /mnt/pixel
sudo chown -R $USER:$USER /mnt/pixel
#+end_src
* Mount & Access the Phone's File System
Finally, plug-in and mount the device, and you should be able to see all storage
(internal and external) inside your new folder!
#+begin_src sh
jmtpfs /mnt/pixel
#+end_src
The output should look something like this:
#+begin_src sh
Device 0 (VID=18d1 and PID=4ee1) is a Google Inc Nexus/Pixel (MTP).
Android device detected, assigning default bug flags
#+end_src
Now you are mounted and can do anything you'd like with the device's files:
#+begin_src sh
cd /mnt/pixel
ls -lha
#+end_src
From here, you will be able to see any internal or external storage available on
the device:
#+begin_src sh
total 0
drwxr-xr-x. 3 user user 0 Jan 1 1970 .
drwxr-xr-x. 1 root root 10 Oct 4 13:29 ..
drwxr-xr-x. 16 user user 0 Apr 21 4426383 'Internal shared storage'
#+end_src
