Samsung Galaxy M13 Power Buttom Flex Cable

 Samsung Galaxy M13 Power Button Flex Cable

The Power Button Flex Cable is a crucial internal component of the Samsung Galaxy M13 that enables the function of the physical power button and, for the M13 models that use it, the fingerprint sensor.

This part is typically a thin, ribbon-like circuit board (Flex PCB) that runs from the location of the external button key to the main motherboard of the phone.

 Functionality

• Power On/Off/Lock: It registers the press of the external power button and sends the signal to the phone’s main board to turn the device on/off or lock/unlock the screen.
• Fingerprint Sensor (on compatible models): In many Samsung Galaxy M-series phones, the power button doubles as the fingerprint scanner. The flex cable integrates this sensor, allowing you to use your fingerprint for security.
• Volume Control (sometimes combined): In some designs, the power and volume button circuitry are housed on the same or adjacent flex cables.
