What is the microphone sub-board on the Galaxy Note 20 Ultra 5G for?
The microphone sub-board is the small intermediate circuit that connects the microphone to the phone's motherboard. It carries the voice picked up during a call, a voice recording, or a voice command. A weakened solder joint or a drop is enough to break this connection, even though the microphone itself remains intact.
On the Samsung Galaxy Note 20 Ultra 5G, replacing this board rather than the entire microphone allows for a more targeted repair, without disassembling the whole audio assembly.
Signs of a faulty board
A caller who can no longer hear anything during calls, while the speakers work normally, almost always points to this component. Same diagnosis if the voice assistant no longer responds, or if recording apps stay silent despite a microphone tested as working.
Before ordering, it's worth checking that the problem isn't debris stuck in the microphone grille: a simple cleaning sometimes fixes what seemed like an electronic fault.
What is a Samsung Service Pack part?
The title of this listing says it: Service Pack. This means a genuine manufacturer part, delivered in Samsung's dedicated repair packaging, the one authorized centers receive for their repairs. Nothing has been replaced or reglued: it's a new part, from the official supply chain, packaged for repair rather than for factory assembly.
This distinction matters when buying: a Service Pack microphone sub-board is neither a copy nor a refurbished component. It corresponds to what an authorized repairer would fit on the same model.
Compatible with which Galaxy Note 20 Ultra 5G?
This microphone sub-board is designed for the Samsung Galaxy Note 20 Ultra 5G. The manufacturer reference GH96-13570A lets you check, before ordering, that it is indeed the part fitted on this device.
A slightly different connector or placement from one generation to the next is enough to make a sub-board incompatible with another model: the manufacturer reference remains the most reliable marker for a repairer.
Fitting and precautions
Accessing the microphone sub-board requires opening the phone's chassis down to the ribbon cable connecting it to the motherboard. The connector is small and disconnects easily with a suitable tool, without forcing the ribbon cable itself.
As with any smartphone repair, the phone must be turned off and the battery disconnected before handling this component, to avoid any short circuit on the motherboard.
Warranty
This part is covered by a 2-year warranty.
