dragging problems

[overhead]

Touchscreen goes crazy when dragging. Am typing this on the device, which is an experia z1 tablett, so it works to tap. When dragging the input jumpsaround the whole screen, will try toattach video where i ammakingsmal circles in the middle of the screen. Have cleaned the screen thorouly, no scratches. Is the solution software or is the tablet scrap?
