Is your iPhone 16 Pro power button not working, failing to lock or wake the screen, or responding only sometimes? In this HowFixit guide, I'll show you how to replace the Side Button and Camera Control flex cable step by step.
Follow the disassembly needed to reach the button flex cable beneath the logic board, including back glass, battery, camera, display, and logic board removal. Then install the replacement cable, reassemble the iPhone, test both buttons, and replace the display and back glass sealing adhesive.
I also explain how to check a stuck or hard-to-press button and distinguish a flex cable fault from physical damage. This repair covers the Side Button and Camera Control mechanical click mechanism. The separate Camera Control sensor is not replaced, so light-press or swipe problems may need a different repair.

🌟FAQ:
❓Question: Will a new flex cable fix a stuck power button?
✔️Answer: Not always. Inspect the external button, internal bracket, and surrounding frame for dirt or deformation.
❓Question: Do I need to remove the display and logic board?
✔️Answer: Yes. In the procedure shown, the Side Button flex cable runs underneath the logic board, so I remove both the display and the logic board to access it.
❓Question: Does this button flex cable replacement require soldering?
✔️Answer: The procedure shown uses screws, adhesive, and cable connectors; it does not require soldering.
