I don't believe this has anything to do with the touchscreen sensitivity.
It's for defining how long you need to keep an item touched till the touch is regarded as "held" (like right mouse button), not as a single touch (like a left-click).
Till now, I had three Z2s of different serial number ranges (0, 1xxx, 3xxx, and 4xxx) - I never changed this setting (default: "Kurz" (short)), but ALL Z2s had touchscreen issues; the one with the serial 3xxx that bad as the screen did not respond to anything. I had to restart the Z2 using the hardware reset button.
So sorry; but this just isn't it.
