I agree with you, I feel like I need to put more pressure on this than my Samsung Note 10.1, my SO's iPhone 4s, or even my old LG Optimus & iPhone 3g. I got used to it after a while but I wish there was a way to re-calibrate the screen sensitivity.
If someone knows of a way to do it (without requiring root) I'd appreciate it so much. (Unlocking bootloader/rooting invalidates warranty in the US AFAIK, so I don't want to do it quite yet..)
