SAMSUNG J5 PRIME BACK BUTTON SENSOR

1. Back Button Function: In most smartphones, including the Samsung Galaxy J5 Prime, the back button is a hardware button that allows users to navigate back to the previous screen or exit from the current application.

2. Button Sensor: The back button is not a simple mechanical button but typically incorporates a sensor or switch that detects when it's pressed. This sensor sends a signal to the device's motherboard or controller to perform the desired action.

3. Location: The back button is usually located on the lower front part of the smartphone, near the device's physical "Home" button (if present) and other navigation buttons.

4. Replacement: If the back button sensor is damaged, unresponsive, or malfunctioning, it may require replacement to restore proper functionality.

5. Professional Repair: Replacing the back button sensor often requires technical expertise and the necessary tools for disassembling the device. It's recommended to have the replacement performed by a skilled technician or at an authorized service center to ensure proper installation and avoid further damage.
