Power Button Fingerprint Sensor Flex Cable A13

The Power Button Fingerprint Sensor Flex Cable for the Samsung Galaxy A13 is a dual-function internal replacement component designed to restore both physical button input and biometric authentication to your device. Because the Galaxy A13 incorporates its fingerprint scanner directly into the frame-mounted side key, this single assembly unifies the tactile power button mechanism and the capacitive biometric scanner onto one flexible ribbon circuit.

Key Features & Specifications

• Dual-Function Assembly: Integrates the tactile power key (dome switch) and high-precision biometric fingerprint scanner into a single module.

• Direct OEM Fit: Manufactured to exact factory specifications for precise alignment within the phone’s inner frame and chassis.

• High-Conductivity Flex Circuit: Premium ribbon cable engineered to deliver stable power signal transfer, fast response times, and reliable biometric readings.

• Pre-Attached Motherboard Connector: Features a plug-and-play terminal connector designed to snap directly onto the main logic board without soldering.

Common Symptoms Requiring Replacement

Installing a new power button fingerprint flex cable will resolve issues such as:

• Unresponsive Power Button: The physical button no longer clicks, feels stuck, or fails to lock/unlock the display.

• Biometric Sensor Errors: The fingerprint scanner fails to recognize prints, reads intermittently, or causes the “Fingerprint sensor not responding” error in Android settings.

• Missing Settings Option: The system no longer detects the biometric hardware, causing fingerprint menu options to disappear completely.

• Torn Cable Assembly: Physical damage, tears, or sharp bends caused to the original flex cable during a previous screen, frame, or battery replacement.

Hardware Compatibility & Model Variants

Samsung produced distinct hardware revisions of the Galaxy A13 series. The flex cables are not cross-compatible between 4G and 5G models. Please verify your model number prior to purchase:
