You install either GSConnect (Gnome Shell) or KDE-connect (KDE) on your Linux PC/Laptop.
You install KDE-connect on your android phone/tablet/e-reader. (Google Play)
You also need to install SSHFS on your Linux PC/Laptop to browse the filesystem.
After that you can "pair" your Linux PC/Laptop with your Android device and "mount" your device storage and start browsing in your file browser.
Great way to copy e-books or other media files to/from your device. You can also see things like battery status, notifications and copy over URL:s. You can even get your phone to start making noise so you can find it...
Works fine with my Bouye Likebook Plus and my Huawei Mediapad 5 as well as on my Android phone.
