Has anyone had this issue? The pen will randomly start having inconsistent input. Sometimes it doesn't recognize at all, and other times it will shoot inking downwards. The eraser works very sporadically and sometimes not at all also. It's weird because this problem can go away for hours or even days, then come up again. Some things I have tried are changing power source, unplugging power, removing battery and reinserting battery into pen, touching pen to screen then inserting battery, 2 button reset, factory restore (to a point where the issue didn't occur), changing pen batteries, buying a replacement pen. Nothing seems to fix this other than it fixing itself sometimes. I will gladly try anything you guys suggest to fix this. Update: I discovered I only have this issue with my palm touching the screen. If you're able to help me figure this issue out, it's probably going to be a fix that addresses repairing palm-rejection functionality.
