4 Get your Android device working under Linux Mint(KDE)
Independent developers have done an incredible job at bringing Android support to GNU/Linux. In order to be able to connect and access your Android devices from KDE's Dolphin, search for kio-mtp (select the version of Linux Mint you are running). If the package is still in 'testing/unstable' stage, LInux Mint will ask you to deliberately click on the button 'Show unstable package' so that you are aware of the fact) and then the rest it one-click install.
It will also add and enable that repo where the packages is hosted so you can get future updates automatically. Do the same process for 'libmtp' and once both these packages are installed, reboot your system. Now you can connect and access your Android devices from Linux Mint
