Overview
What this part is
The USB-C port on the Galaxy S26 Ultra is soldered to a small board at the bottom of the phone. Daily plugging in, pocket lint and liquid can wear or corrode it, so the cable feels loose, charging stops and starts, or a computer does not see the phone.
This board replaces the whole port assembly for the Galaxy S26 Ultra SM-S948B. Before ordering, try a different cable and charger and clean the port gently with a wooden or plastic pick, as lint is a common cause.

Before you order

How to check your model
Open Settings › About phone. The model name should read Galaxy S26 Ultra, not Galaxy S26 or Galaxy S26+. The model number should read SM-S948B.
If the phone charges wirelessly but not by cable, the port board is the likely fault.
Professional installation
How a technician fits this part
- Power off the phone and warm the back glass to soften the adhesive.
- Lift the back glass and disconnect the battery.
- Remove the lower cover and speaker, then unclip the flex cables from the old board.
- Fit the new board and reconnect every cable firmly.
- Reconnect the battery and test wired charging and a computer connection.
- Refit the parts and back glass with new adhesive.
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 S26 Ultra?
Yes, if Settings › About phone shows Galaxy S26 Ultra with model number SM-S948B.
Does it fit the Galaxy S26 or S26+?
No. Those models use different charging boards.
Will it fix wireless charging?
No. Wireless charging uses a separate coil. This board only fixes charging and data through the USB-C port.
Is it made by Samsung?
No. It is a brand new, OEM-quality charging port board made to fit the Galaxy S26 Ultra, and every part is tested before dispatch.
Should I fit it myself?
We recommend professional installation. The back glass has to be heated and lifted, and several cables are unclipped to reach the board.
How quickly will it arrive?
