How to Tell When the Connection Flex Cable Needs Replacing

The connection flex cable of the Samsung Galaxy M52 5G ensures communication between the motherboard and external components: volume buttons, power button, proximity sensor. When this flex cable is damaged, the phone no longer responds to button presses, or recognizes them intermittently. The proximity sensor may also stop working, leaving the screen on during calls. This is an original manufacturer part supplied in Service Pack packaging, new and untreated, identified by its reference GH59-15514A.

Before ordering, verify that the malfunction is indeed caused by this flex cable: test the buttons in the device settings to rule out a software lock. If multiple buttons respond only intermittently, or not at all, the flex cable is probably the cause. A faulty flex cable can also be recognized by unexpected restarts or a screen that never turns off during calls.

Compatibility with Samsung Galaxy M52 5G

This flex cable is designed exclusively for the Samsung Galaxy M52 5G (model M526). It fits inside the internal compartment and connects directly to the motherboard to activate all the phone's control elements. Before placing your order, verify that you have a Galaxy M52 5G by checking your phone's settings (Settings > About phone). Any other model, even similar ones in the Galaxy M range, requires a different part.

What's in the Package

You receive the connection flex cable only, ready to be installed. It is new, supplied in its Samsung workshop packaging without having undergone any refurbishment. No tools are included: installation requires a precision screwdriver to access the internal compartment and disconnect the old flex cable before connecting the new one.

Installation and Essential Precautions

Installing this flex cable requires opening the phone and carefully disconnecting existing flex cables. This is an internal procedure that risks damaging other components if not performed carefully. The flex cable itself is fragile and must be handled without bending its connectors. Strictly follow the reverse assembly order when closing the device to avoid short circuits. If you are not comfortable with micro-electronics, entrust this repair to an authorized professional.

Warranty and Commitment

This original manufacturer part comes with a 2-year warranty. It covers manufacturing defects and failures occurring under normal usage conditions. The warranty does not apply to damage related to installation, impacts, or submersion. Keep your invoice and proof of purchase to assert your rights in case of any issue.
