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.
