How to tell when the main ribbon cable needs replacing

The main ribbon cable of the Galaxy S20 Plus connects the motherboard to all internal components of the device. Its failure manifests through seemingly random malfunctions: the screen no longer responds to touch in certain areas, calls fail to connect, mobile data disappears without reason, or the device restarts spontaneously. Unlike a software failure, these symptoms persist after a complete restart and are not related to an update. If your phone displays these signs, the main ribbon cable has likely suffered a connection break or corrosion.

A faulty ribbon cable cannot be repaired: it must be replaced. This original manufacturer ribbon cable supplied in Service Pack is identical to the one that left the Samsung factory during initial assembly. It restores reliable connection between the motherboard and components, thereby restoring normal operation of your device.
