Explanation
A drifting cursor on a touchscreen tablet - in the absence of visible physical damage - is a classic symptom of a miscalibrated digitizer. Calibration maps the touch sensor grid to the display coordinates; when it drifts out of alignment, touch inputs register offset from where the user actually touched. Physical damage (A) is ruled out by the technician's observation. Screen rotation (B) would cause touch inputs to be mirrored or rotated, not drift. A depleted touch-pen battery (C) would affect stylus input, not general cursor behavior on a standard capacitive touchscreen.
