This could be a case of a bad digitizer or just an improperly seated cable. Confirm that this issue is consistent in any app. If the issue is consistent, check the digitizer cable and socket for damage or debris. Re-seat the connector and see if re-seating (and/or cleaning) fixed the issue. If not the issue may be a bad digitizer. Hope this helps and let us know what happens.
