Replacement Charging Port Board for Samsung Galaxy Note 8 and Note 9

Replacement Charging Port Daughter Board for Samsung Galaxy Note 8 and Note 9

Restore wired charging and related lower-board functions on a compatible Samsung Galaxy Note series device with this replacement charging port daughter board.

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

The Samsung Galaxy Note 8 and Galaxy Note 9 use different daughter boards. 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 flex cable, software problem, liquid ingress, or another defective component.

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

Proper diagnosis is recommended before replacing the charging port daughter board.

Product Quality Notes

This replacement daughter board 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, antenna performance, board appearance, component markings, and included subcomponents may vary depending on the component grade and production batch.

Depending on the model and supplier, the daughter board may include:

• USB-C charging connector
• Lower microphone
• Antenna contacts
• Spring contacts
• Board connectors
• Supporting electronic components

Included components may vary. Compare the replacement board carefully with the original part before installation.

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

Regional and Carrier Compatibility Notice

Samsung Galaxy Note devices were produced in multiple regional, carrier, and chipset configurations.

A board designed for one SM-N950 or SM-N960 variant may not function correctly in another variant, even when the external phone model appears identical.

Differences may include:

• Daughter-board shape
• Connector position
• Antenna contacts
• Microphone configuration
• Supporting components
• Cellular antenna routing
• Regional or carrier-specific circuitry

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

Installation of an incompatible board may result in poor charging, microphone failure, weak or missing cellular reception, USB problems, or other functionality issues.

Installation Notes

Professional installation is strongly recommended.

Replacing the daughter board requires opening the rear housing and carefully removing internal components. Improper handling may damage the rear glass, display, battery, wireless charging assembly, loudspeaker, S Pen components, antennas, mainboard, flex cables, or connector sockets.

Before final installation:

• Confirm the complete Samsung model number
• Compare the replacement board with the original part
• Inspect the board shape, connectors, contacts, and mounting points
• Disconnect the battery before removing or connecting components
• Inspect the mainboard-to-daughter-board interconnect flex cable
• 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 the lower microphone
• Test calls, voice recordings, and speakerphone operation
• Check loudspeaker operation
• Test cellular signal and mobile-data connectivity
• Test Wi-Fi, Bluetooth, and GPS where appropriate
• Confirm that no moisture or charging warning remains
• Test wireless charging to identify unrelated charging faults
• Confirm S Pen detection and charging where applicable

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

The USB-C port must be correctly aligned with the frame opening before screws are tightened. 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 daughter board and USB-C port 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 or carrier compatibility
• Debris, lint, dirt, or contamination inside the USB-C port
• Bent, broken, damaged, or corroded connector pins
• Damaged board connectors, contacts, or electronic components
• Torn, folded, punctured, stretched, or damaged flex cables
• Damaged microphones, antenna contacts, or grounding points
• 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
• Problems caused by a damaged interconnect flex cable
• 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.
