There are many alternatives to PaintTool SAI that work on Android, but PaintTool SAI is not available on Android. MediBang Paint is the best Android alternative for free. Paint Tool SAI won’t work on my tablet; the cursor won’t move at all. You should uninstall all tablet drivers, including those for your XP-Pen. You can do this by opening Start > Control Panel > Programs and Features and checking the list of programs. Reboot your computer after you have uninstalled any tablet software.
