I've noticed the S-pen on my phone does not point exactly to where I touch on the screen with it. Noticed it mostly on the Snote pad, cause that's got a grid of tiny squares (like graph paper). Always prod the wrong square. (and no it's not my eyesight!!) I've tried the *#1*# (or whatever) test menu, but that doesn't allow you to calibrate, but merely test various aspects of the phone, rather than alter them. Any tips?
