Keeps getting better and better I have S5 Android 4.4 and this app works on my Ubuntu 16.04 Transferring files are very easy and 100 times faster then Bluetooth 4.0. Transfer files from and to mobile phone. I use the clipboard copy feature heavily. I use it on my workstation  desktop and laptop and so far no crashes or failures. Good job KDE I am very satisfied. I am so proud of this app. Thanks for the repo ppa developer.
