Power On/Off Flex Cable Samsung Galaxy S10

The Power On/Off flex cable of the Samsung Galaxy S10 transmits commands from the power button to the motherboard. When this button no longer responds, remains stuck, or activates by itself, this flex cable is generally the cause. It is located under the side chassis, wedged between the screen and the back cover. Replacing this part restores the device's startup and shutdown functions without affecting other components.

This flex cable is a compatible part, manufactured to ensure the same functions as the original manufacturer part. It allows you to offer a repair at an affordable price while maintaining the smartphone's reliability. The repair time remains short since only this flex cable needs to be replaced.

Recognizing Power Button Wear

The power button wears gradually. The first signs appear when you need to press it several times for the phone to respond, or when it remains pressed despite light contact. If the Galaxy S10 turns off by itself without user action, or refuses to start for no apparent reason, the Power flex cable is often the cause. A forced restart sometimes confirms the diagnosis: if the device accepts a key combination but refuses the Power button alone, it is indeed the flex cable that needs to be changed.

Installation and Precautions Before Replacement

The Power flex cable of the Galaxy S10 is located near the side button, in a tight space between the touchscreen and the chassis. Disassembly requires removing the screen properly and disconnecting several connectors before accessing this part. Careful work avoids bending the flex cable itself or damaging the contacts on the motherboard. It is recommended to check the condition of the connector on the new flex cable before reassembly, as a poorly secured connection would leave the button ineffective.

Warranty and Exact Compatibility

This flex cable is guaranteed 2 years by the shop. It equips the Samsung Galaxy S10 G973, the standard model. The supplier also offers this same part for the Galaxy S10 Plus G975 under the same commercial reference, because the flex cable is identical on both devices. Before ordering, verify your customer's device model by going to Settings > About Phone. A Galaxy S10e G970 or a Galaxy S10 Plus will require verifying exact compatibility on the corresponding product sheet.
