Device::Find failed:Device is already used by another process

I failed to mount my mtp device to a directory. Error: Device::Find failed:Device is already used by another process

I use:
Arch linux
KDE, Dolphin

I can view file in mtp device using Dolphine, but can't mount it by executing aft-mtp-mount ~/mnt.

MTP is exclusive, meaning that you can't access to the same device using different apps. You have to close/kill any apps accessing your device first. Try running UI app, it will offer you to kill the other processes.

I found my mtp device is used by kiod5. I can mount it if I killed kiod5.

With a fresh install of Kubuntu 21.10, I found that I could no longer use go-mtpfs

I had never heard of 'aft' , literally stumbled upon it searching for an answer to mount this Galaxy S5. Also the problem was compounded by Dolphin connecting automatically to the phone.

Initially I got

aft-mtp-mount ~/myphone

Device::Find failed:Device is already used by another process
connect failed: no MTP device found

then found this issue, went into the GUI and killed the process that was using the phone. It was kiod5. Exited the GUI and ..

aft-mtp-mount ~/myphone

your device does not have android EditObject extension, mounting read-only

I only need read-only mode. It mounted just fine, exactly as required.

So, a HUGE thanks to the developers of "android-file-transfer-linux"
