For Samsung A21 , A215 - Replacement Home Button , Fingerprint Reader Scanner - Green

Restore secure authentication and rapid device unlocking with this High-Sensitivity Capacitive Fingerprint Scanner. Specifically engineered for the Samsung A21 (SM-A215), this module features a precision-molded contact surface finished in the factory-original Green colorway. It utilizes a high-density FPC (Flexible Printed Circuit) for low-latency communication with the motherboard’s secure enclave. This component is essential for resolving hardware-level biometric failures such as "Fingerprint hardware not available" errors, unresponsive touch recognition, or physical damage to the rear-mounted scanner that compromises the device's security protocols.
