Description

The CS40L26 chip is strictly responsible for processing the intricate data received from the under-display ultrasonic fingerprint scanner and transmitting it securely to the CPU. When the device experiences severe impacts or liquid ingress, the solder joints of this IC can fracture, or the chip itself can fail internally. This results in complete biometric failure, even after replacing the screen or the sensor module itself. Replacing this component fully restores the phone’s ability to read fingerprints with its original biometric speed and precision.

Technical Specifications & Features:

• Broad Flagship Compatibility: Precision-engineered to perfectly match the logic boards of the entire Samsung Galaxy S23, S24, and S25 lineups.

• OEM Biometric Performance: Guarantees highly accurate processing of ultrasonic data, ensuring instantaneous screen unlocking without any delay.

• Definitive Hardware Fix: Directly resolves persistent fingerprint faults that are not fixed by screen replacements or factory resets, pointing strictly to logic board circuit failures.
