Ubuntu doesn't recognize my Galaxy 9 phone

Solution 1:

I had a similar problem but with Samsung S6 Edge. I used Android File Transfer for linux and it worked! Worked fantastically actually! In a nutshell,... "It just works!"

You will have to download and build it from Github: https://github.com/whoozle/android-file-transfer-linux

Just to add to the limited instructions on the "how to build page" on Github for the less technical, also google's your friend if the instructions underneath aren't clear enough;

1. ~$ sudo apt-get install build-essential cmake libqt4-dev ninja-build libfuse-dev libreadline-dev
2. Find a path in your pc where you want to keep the source code for AFTL
3. Clone AFTL to that location then as the instructions on the github page says...
4. ~$ mkdir build
5. ~$ cd build
6. ~$ cmake ..
7. A little bit of a modification here to build things much faster! ~$ make -j<number of cores you have>. So in my case with an i7 cpu it s ~$ make -j8
8. ~$ cd qt
9. ~$ ./android-file-transfer
10. In many computers it will give you some pop-up error saying that there is already some other process or rather using MTP or busy or something similar. It will give you the option to kill them by pressing "abort". DO THAT! It will kill those useless non-function processes. Then you will get AFTL running showing you all the folders on your phone.
11. Have fun!
