Basically I suspect that certain functions of the multitouch object are FUBAR'd, but I'm absolutely open to the possibility that I'm just doing this wrong.
I'm attempting to move the object relative to the touch position. I been struggling with this for months & this is the closest I can get to it.
Test this MFA on windows & then build an APK & test on device.

For me, it works more or less as-expected on windows. There is some very slight glitching, but more or less works properly
On Android however, the Ydelta is always off, initially by about -100, & then gradually varies depending on the velocity of the drag motion. This causes my object to "teleport" on the Y-axis on a new touch occuring, which is not the desired behaviour.
I'd greatly appreciate anybody taking a look at this to see if they have the same issue I'm having on my device.
