Pen Issues

[JingMing]

I am having a strange issue with pen. When sp3 is plugged into ac power the pen writes like crap missing strokes in OneNote (both metro and non metro version) and when the sp3 is running on battery it writes like a charm... anyone else experiencing this? I have in i7 512gb model...I tried replacing pen and that didn't work.

I am glad I am not the only one having this problem. Yes I am facing this problem too, the only solution for the time being for me is to unplug when i am trying to use the sp3 pen. Hope the coming firmware update helps.

Beside this, do any of you guys faced the problem that SP3 pen sometimes will randomly inking at the bottom of the screen while your pen tips are actually writting at the middle of the screen?
