Expose setting to prevent automount
By default, connecting an Android device (Redmi 10) automounts it (so that we can browse it with the file manager).
However, this prevents Shotwell (the default Gnome photo manager) to import the photos, because the device is "already used".
To avoid the problem, I used this workaround:
gsettings set org.gnome.desktop.media-handling automount false
However, I think an option to disable automount should be exposed in the settings UI, because without disabling this option it is not possible to import photos from an Android device.
Note: In removable drive settings, even if all actions are disabled, the device is still considered "already used" when trying to import from Shotwell.
