How to tell if this ribbon cable needs replacing

The volume and power buttons on your Galaxy S20 Plus are no longer responding, or only responding erratically. You press them with no result, or the device reacts with a delay. This Power + Volume ribbon cable is the original part that controls these two functions. Replacing it restores normal responsiveness, the same as when you first bought the device.

Before ordering, verify that your device bears the reference SM-G985F or SM-G986B engraved under the battery or on the side chassis. This is the ribbon cable that fits your exact model.

Tested before shipping, it guarantees installation without modification and responsiveness identical to the original. You get back exactly the button behaviour your device had when new.
