Ubook Pro m CPU - H6

Hello for now,

someone here happens to have the same error - When I write in note with the H6 pen, for example, everything works fine, but sometimes the pen jumps up and down or stops completely, which makes writing and drawing a bit tiring in the long run. Is there a fix for this ? I can also take a picture of it. I’ve tried one Note, Whiteboard and other apps, that’s not the reason.

Best regards

Your Spirit
