Touchscreen multitouch radius of interaction is a lot more than previous S 8.4

I'm not exactly sure how to word this but two fingers on the screen close together doesn't work as well as my Tab S 8.4. On the 8.4, I could have the sides of my index and middle finger touching and the screen would recognize this as two separate points. This freaks the S2 8.0 out, and my fingers tips must be close to 3/4" inch (2cm) apart for them to be recognized as two points.

Is this a hardware thing, or is there a way to adjust this in software? Or am I going to have to custom build a kernel?
