The central control screen is a display located on the central console, primarily showing car audio, vehicle information, rearview camera images, etc. It can be a single-touch or multi-touch LCD screen, operated via physical buttons.
My car's central control screen also had random jumping issues before, and I've specifically researched this problem. Generally, it's most related to system software - the program freezes while running, causing the screen to register phantom touches. The simplest solution is to force restart by long-pressing the power button - remember to hold it for over 10 seconds until the screen completely turns black before releasing. If restarting doesn't work, try a factory reset (this option can be found in system settings), but make sure to note down your Bluetooth and navigation configurations beforehand. Also pay special attention to screen protectors - some low-quality tempered glass films on the market can affect touch sensitivity, and you'll immediately notice the difference after removal. Wiring issues are also common, like loose connectors or dust in ports causing poor contact - this is best diagnosed by a dealership using professional equipment. For daily use, regularly clear background apps as full memory will slow down screen response.
Over the past decade of driving, I've encountered several instances of the central control screen malfunctioning, each with different causes. Once, the screen suddenly filled with static and started changing songs on its own; it turned out that moisture had seeped into the dashboard during windshield tinting, and it took three days of airing out to return to normal. If the car is driven over rough roads frequently, the wiring behind the screen can loosen, and sometimes tapping the side of the dashboard might help. Software conflicts are particularly troublesome—after installing a knockoff navigation app last time, the screen started flickering, but it stopped immediately after uninstalling. I recommend regularly updating the system via USB, as the patches pushed by manufacturers can fix many minor issues. If the cause remains elusive, it's best to head straight to the repair shop; never attempt to dismantle the screen casing yourself, as the delicate components inside can easily be damaged. Nowadays, new cars are internet-connected, and some brands even allow remote rebooting of the central control via a mobile app.
