Overview
What this part is
The USB-C port on the Samsung Galaxy S25 sits on a small board at the bottom of the phone. Dirt, liquid or a worn cable can damage the pins, so the phone charges slowly, only at an angle, or not at all, and may not connect to a computer.
This replacement board fixes those port faults. First, clean the port gently with a wooden or plastic pick and try another cable and charger. If charging still fails, the board is a likely cause. The phone opens from the back, so the job needs heat, the right tools and new adhesive.

How to check your model
Open Settings › About phone. The model name should read Galaxy S25 and the model number should be SM-S931B. The model number is also printed on the box.

Professional installation
How a technician fits this part
- Power the Galaxy S25 off, remove the SIM tray and warm the edges of the back glass to soften the adhesive.
- Lift the back glass, remove the screws and covers, and disconnect the battery before anything else.
- Remove the lower covers and loudspeaker, disconnect the port board flex and unscrew the old board.
- Fit the new board, reconnect all flex cables and the battery, then test charging and USB data before sealing.
- Refit the covers and screws, apply new adhesive and press the back glass down evenly while it cures.
- Run a final check on the Galaxy S25: calls, signal, speakers, buttons, cameras and charging.
Check that the part matches the device before fitting it or removing any adhesive backing. Once a part has been fitted, it cannot be returned for a change of mind. Faulty parts are always covered.
FAQ
Frequently asked questions
Will this fit my Galaxy S25?
Yes, if Settings › About phone shows model number SM-S931B. It does not fit the Galaxy S25+, S25 Ultra, S25 Edge, S25 FE or any other model.
Does it fit the Galaxy S25+?
No. The Galaxy S25+ (SM-S936B) is a larger phone with different internal parts. This part is for the standard Galaxy S25 (SM-S931B) only.
Will it support fast charging?
It restores the charging port, so normal charging and fast charging should work again with a compatible Samsung charger and cable. If the battery is worn or the main board is faulty, charging may still be slow.
Is it made by Samsung?
No. It is a brand new, OEM-quality USB-C charging port board made to fit the Galaxy S25, and every part is tested before dispatch.
Should I fit it myself?
We recommend professional installation. Opening a Galaxy S25 means heating and lifting the back glass, disconnecting the battery safely and resealing with new adhesive.
