Product Description

The SAMSUNG gh81-23273a is a side key flexible printed circuit board (FPCB) assembly designed as a service replacement component for Samsung mobile devices. This part handles the physical button input signals for side-mounted keys, translating mechanical button presses into electrical signals recognized by the device. It is typically replaced by mobile device repair technicians when side buttons become unresponsive, intermittent, or physically damaged.
