Tested replacement built for repair benches. This home key button PCB membrane flex cable is made for the iPhone 4S, and each unit gets checked for good condition before it leaves our warehouse.
What You’re Getting
You receive one home key button assembly on a PCB membrane flex cable. The membrane carries the home button press to the logic board, so a worn or faulty unit can cause sluggish or missing presses. Swapping in a fresh flex brings that main button back to life.
Why This Part Works
Your home button handles unlocking, returning to the home screen, and Siri activation, so a dead button slows down daily use. This flex is built for the 4S specifically, so the connector and button position line up with the original design. Nothing needs modifying to fit.
Installation Notes
Work on a clean, well-lit bench. Always wear an ESD strap to protect the logic board from static. Test the phone before you install anything, so you know the fault is really the button. Keep the cable bend under 90 degrees, because sharp folds can crack the membrane. Professional installation is the safest route if you are new to phone repairs.
