Shield: External Touchscreen Rotation in Console Mode


I have an external touchscreen (PQ Labs G4) that I want to hook up to my Shield Tablet using USB OTG. It is mostly working, except that when in console mode, the touchscreen input is rotated 90 degrees.

I’ve also tried compiling the open source Android build, because I found a thread with a potential fix to the problem (, but the open source version doesn’t appear to even have console mode support.

When using Mirror mode, the touchscreen works perfectly, but then I get cropped sides to the display, and don’t get the 4K resolution I’d like.

Thanks for any help you can provide!
