Question:

Why are two lines unintentionally connected when testing the touch function on my Galaxy S20 FE using the "Touch Screen Test App"?

 

Answer:

The "Touch Screen Test App" does not display the touch information provided by the Galaxy S20 FE accurately. This issue occurs within the app and does not affect the actual functioning of the touch screen in regular usage. Actual apps operate based on accurate touch information provided by the device.
