Explanation
When a tablet is dropped and one portion of the touchscreen stops responding, the most likely cause is physical damage to the digitizer - the component that detects touch input - not the display itself. Testing the digitizer confirms whether it is functioning and identifies the extent of the damage before any other steps are taken. Updating drivers would address software-level touch issues, not physical damage from a drop. Replacing the screen protector removes a surface layer with scratches but cannot restore a damaged digitizer underneath. A factory reset addresses software problems and would not fix hardware damage caused by physical impact.
