Is there any particular reason why only two fingers are tracked by the touchscreen on Sabre i.MX6Q board? We see that with both Linux and Android images.

Thanks,

-Ben

There is no particular reason. The HW supports more than 2 touches, however the SW delivered only enables 2. You can  modify the driver to enable more than 2 touches.
