When the device no longer turns on, restarts without reason, or the Power button does not respond, this flex cable is often the cause. Its replacement restores control of the device and the reliability of its power on and off functions. Here is the original manufacturer version, compatible with the Galaxy S23 Ultra.

An original part selected and inspected

This Power flex cable is an original Samsung part. It comes from the manufacturer's production line and meets all technical specifications of the Galaxy S23 Ultra.

It has been verified before shipment to rule out any manufacturing defects, ensuring immediate reliability after installation.

Installation and precautions

Replacing the Power flex cable requires disassembling the device and accessing the motherboard. This operation requires specialized tools, including a disassembly kit and good knowledge of electronic assembly. The flex cable connects to a connector on the motherboard. Any mishandling risks damaging the connector or other nearby components. If you are not trained in this type of repair, calling on a professional remains preferable.
