Replacement Charging Port Flex Cable for Samsung Galaxy S8, S8 Plus, S9, and S9 Plus

Replacement Charging Port Flex Cable for Samsung Galaxy S8, S8 Plus, S9, and S9 Plus

Restore wired charging and related lower-device functions on a compatible Samsung Galaxy S series device with this replacement charging port flex cable.

This internal component is designed to replace a damaged or defective USB-C charging port flex affected by intermittent charging, failed USB connections, loose cable fitment, microphone problems, physical connector damage, or other hardware-related faults.

The Samsung Galaxy S8, Galaxy S8 Plus, Galaxy S9, and Galaxy S9 Plus use different charging port flex assemblies. Select the exact phone model and model number before ordering, as these components are not interchangeable.

Common Charging-Port Failure Symptoms

Replacement may be appropriate when the device:

• Does not charge through a USB-C cable
• Charges only when the cable is held at a particular angle
• Repeatedly connects and disconnects while charging
• Displays a moisture, accessory, or charging-related warning
• Is not detected by a computer
• Cannot complete USB data transfer
• Has a loose, bent, damaged, or corroded USB-C port
• Has compacted debris that cannot be safely removed
• Charges slowly despite using compatible charging equipment
• Does not activate Samsung fast charging
• Has poor microphone performance during calls or recordings
• Produces muffled, distorted, quiet, or intermittent lower-microphone audio
• Stops charging after impact or liquid exposure
• Charges wirelessly but not through the USB-C connector

These symptoms may also be caused by a defective battery, damaged USB-C cable, unsuitable power adapter, contaminated connector, charging-control circuit fault, mainboard damage, damaged interconnect cable, software problems, liquid ingress, or another defective component.

A persistent moisture warning may be caused by moisture, corrosion, contamination, software, the charging port flex, its connector, or the mainboard. Replacing the flex cable does not guarantee that the warning will be resolved.

Proper diagnosis is recommended before replacing the charging port flex cable.

Product Quality Notes

This replacement charging port flex cable may be aftermarket, refurbished original, pulled original, or otherwise sourced depending on the selected product option and available inventory.

Charging speed, USB-C connector fitment, microphone performance, data-transfer stability, flex-cable appearance, component markings, antenna performance, and included subcomponents may vary depending on the component grade and production batch.

Depending on the model and supplier, the charging port flex assembly may include:

• USB-C charging connector
• Lower microphone
• Flex-cable connectors
• Antenna or grounding contacts
• Supporting electronic components
• Mounting or alignment sections

Included components may vary. Compare the replacement flex carefully with the original component before installation.

A replacement charging port flex will not resolve charging problems caused by the battery, mainboard, charging-control circuitry, damaged board connectors, unsuitable accessories, or software.

Regional, Carrier, and Chipset Compatibility Notice

Samsung Galaxy S8 and Galaxy S9 series devices were produced in multiple regional, carrier, and chipset configurations.

A charging port flex cable designed for one SM-G950, SM-G955, SM-G960, or SM-G965 variant may not function correctly in another variant, even when the external phone model appears identical.

Differences may include:

• Flex-cable shape
• Connector position
• USB-C port design
• Antenna or grounding contacts
• Microphone configuration
• Supporting electronic components
• Cellular antenna routing
• Regional or carrier-specific circuitry

Confirm the complete model number and visually compare the original and replacement components before installation.

Installation of an incompatible charging port flex may result in:

• Failed or intermittent charging
• Slow or unavailable fast charging
• Microphone failure
• USB data-transfer problems
• Moisture-detection warnings
• Weak or missing cellular reception
• Poor antenna performance
• Other lower-device functionality problems

Charging port flex cables are not interchangeable between the Galaxy S8, S8 Plus, S9, and S9 Plus.

Installation Notes

Professional installation is strongly recommended.

Replacing the charging port flex cable requires opening the rear housing and carefully removing internal components. Improper handling may damage the rear glass, display, battery, wireless charging assembly, loudspeaker, antennas, fingerprint-sensor flex cable, mainboard, other flex cables, or connector sockets.

Before final installation:

• Confirm the complete Samsung model number
• Compare the replacement flex cable with the original component
• Inspect the flex shape, connectors, contacts, microphones, and mounting points
• Disconnect the battery before removing or connecting components
• Protect the fingerprint-sensor flex cable when removing the rear cover
• Inspect the related mainboard and interconnect connectors
• Remove dust, lint, corrosion, and debris from the surrounding area
• Test wired charging before resealing the device
• Test charging with more than one known-good cable and adapter
• Confirm standard and fast-charging operation
• Confirm USB connection and data transfer with a computer
• Test compatible USB-C accessories where applicable
• Test the lower microphone
• Test calls, voice recordings, and speakerphone operation
• Check loudspeaker operation
• Test cellular signal and mobile-data connectivity
• Test Wi-Fi, Bluetooth, GPS, and NFC where appropriate
• Confirm that no moisture or charging warning remains
• Test wireless charging to identify unrelated charging faults
• Test the fingerprint sensor before resealing the rear cover
• Check for unexpected restarting or other abnormal behaviour

Do not force connectors into place. Bent pins, damaged sockets, torn flex cables, misplaced screws, or excessive pressure may permanently damage the charging port flex or mainboard.

The USB-C port must be correctly aligned with the frame opening before the surrounding components are secured. Poor alignment may cause difficult cable insertion, incomplete connection, housing pressure, or premature port damage.

No tools, adhesive, rear-cover seal, or installation materials are included.

Water-Resistance Notice

Opening the device compromises the original factory seal.

A replacement rear-cover adhesive seal may help reduce exposure to dust and incidental moisture, but original water resistance cannot be restored or guaranteed after repair.

The charging port flex and USB-C connector must be installed and aligned correctly. Improper installation may leave openings that allow moisture or debris to enter the device.

Avoid exposing a repaired device to water, steam, high humidity, or other liquids.

Warranty

This component includes a 30-day limited parts-only warranty against manufacturing defects, subject to the applicable 3C-Easy Markham Component Warranty.

The warranty does not cover:

• Incorrect regional, carrier, or chipset compatibility
• Installation in an incompatible SM-G950, SM-G955, SM-G960, or SM-G965 variant
• Debris, lint, dirt, or contamination inside the USB-C port
• Bent, broken, damaged, or corroded connector pins
• Torn, folded, punctured, stretched, or damaged flex cables
• Damaged flex connectors, contacts, microphones, or electronic components
• Bent connector pins or damaged mainboard sockets
• Damage to the rear glass or fingerprint-sensor flex cable
• Improper installation or incorrect part selection
• Physical, impact, or pressure damage
• Liquid, moisture, or corrosion damage
• Damage caused by excessive heat or soldering
• Damage caused by unsuitable charging accessories
• Charging issues caused by the battery or mainboard
• USB, microphone, antenna, or signal issues caused by unrelated components
• Software, accessory, sensor, or compatibility limitations
• Persistent moisture warnings caused by unrelated faults
• Labour, diagnostics, installation, removal, or related repair costs

The component must be connected and fully tested before final installation.
