Here are some tips for dealing with a malfunctioning central control touchscreen: 1. Incomplete removal of the screen protector: Residual film adhering to the surface can affect sensitivity. This is the easiest issue to resolve—simply remove the screen protector completely. 2. Issues with the screen itself: There can be various causes for this, such as damage to the touchscreen itself, faulty wiring, or loose connections, among others. Most problems caused by the screen itself require professional inspection and repair at a specialized repair shop or 4S dealership. 3. Prolonged use of the screen: You can use a paperclip or toothpick to press the RST hole (reset button) on the central control screen, effectively restoring it to its initial state. Afterward, reinstalling the system should allow normal use.
