I have fixed the back button problem where it registers more than 1 press on the GPD XD+.
Its not software its hardware debouncing.
One 1uf non-polarised capacitor across the button works.
It requires removing the motherboard from your XD+ and looking at the button contact side.
There are 6 test points above the back/home contacts.
Solder a wire to the bottom left test point and solder a wire to ground and put the capacitor across it.
Find a suitable place to put the capacitor, I used a SMD ceramic cap.
I might soon provide a service to do this mod.
