Some detailed observations
Booting XFCE UI:


 * Booting is extremely slow. It stays in the Samsung splash screen for a minute and a half and then starts booting pmOS. However, if I connect the charger when the tablet is powered off, it displays the charging icon as usual, and then starts booting pmOS immediately.
 * Sometimes the screen goes black for a split second and then it returns to normal.
 * Cannot boot into weston somehow. Seems that the interface does not work here. It seems common between other devices that share the same kernel (any DE that uses Wayland).
 * Create a file called /etc/X11/Xwrapper.config with the line `needs_root_rights=yes` to get X working.
 * The tablet freezes when the device is powered off or rebooted (from terminal and from XFCE UI).
 * After a couple of minutes (if using XFCE UI), the tablet is frozen entirely.
 * SSH does not work. If the command `sudo service sshd status` is executed on terminal, system tells me that SSH is currently loaded and functioning. However, it does not seem to work from USB (172.16.42.1) nor from WiFi. Nevertheless, telnet works.
 * I see slightly wrong colors on images.

Booting with MATE makes some differences:


 * The UI does not freeze after a couple of minutes.
 * Reboot/Shutdown works (only via UI).
