[Q] Z3 Tablet driving me crazy (Digitizer/Touch Sensitivity) topic

I have a Z3 Tablet Compact that I preordered. So I have been using it since it was launched.

The tablet is very good in almost every way. The software is very smooth, the design is nice and it's impressively thin.
I also very much appreciate the battery life. With normal usage I get about 7-8 hours of screen on time.

BUT, the digitizer is driving me mad. Too often it just doesn't know when I want to "click" something and when I'm just trying to scroll.
I frequently click something and it just doesn't record it. So I click it again, no big deal. It's the scrolling that's really getting to me.
If I, for instance, try to browse the frontpage of The Guardians mobile site, I find myself accidentally clicking on about four different links before I get to the bottom of the page.
Because of this I have to be extremely careful and try to use the absolute edge of the page for scrolling.
Today I visited a site where I seriously couldn't get past one section of the page. It consisted of large pictures and text covering the full width of the page. These were all links. Every time I tried to scroll it assumed I wanted to click on the picture. I had to give up. That really annoyed me.

Sites or apps with lots of videos grouped together (Youtube for instance) have the same problem.
I have tried changing the value for "Touch & Hold Delay" under Settings>Accessibility as someone suggested on another site. This did not help.

Does your tablets have this issue? Should I demand that they replace it?
Is there maybe an app that you can use to alter the sensitivity of the touch input?

I have or have owned several other android devices and none of them suffer from this problem.
