Dead side buttons making your S26 Ultra frustrating to use? Pressing volume up and down and getting nothing back is a real annoyance, and the power button matters just as much for locking the screen and waking the phone.
What You’re Getting
This is a replacement flex cable that carries the power and volume button circuitry for the Samsung Galaxy S26 Ultra, model SM-S948B. You receive one new cable, not a used or refurbished one. Each unit is checked and in good condition before it leaves our shelves, so you start with a part that is ready to fit.
Why This Part Works
The cable is designed to match the original button layout on the S26 Ultra, so the buttons sit where you expect and respond with the right press feel. Because the power and volume buttons share one flex strip, replacing it addresses both controls in a single job rather than two separate repairs.
Installation Notes
Side-button flex cables are delicate, so take your time. Work on a clean, flat surface and wear an ESD strap to protect the phone’s internals from static discharge. Never bend the ribbon past 90 degrees, since sharp folds can crack the traces and leave you with a second problem. If you are not confident opening the handset, a qualified technician is the safer route.
