iPhone 16 Pro Max Proximity Sensor flex cable replacement helps when the screen does not react as it should. If the display stays on during calls, or if brightness changes feel wrong, the sensor flex may be damaged. Also, drops, frame bends, or past repairs can weaken this area. Therefore, a new flex can bring back stable screen response.
This front sensor flex carries both proximity and ambient light signals, as listed. In addition, it suits repair shops and confident DIY installers. You can target the faulty sensor path instead of replacing the whole device. Also, a clean swap often reduces random screen wake and odd dimming. As a result, daily calling and viewing feel smoother. Plus, you gain more control over how the display reacts to light and face position.
Before you start, test with different apps and basic settings. Then restart the phone and rule out case or screen protector issues. Next, power the device down and organise screws by location. Also, route the flex flat and avoid sharp bends near connectors. After that, test screen on/off behaviour and auto-brightness before final reassembly. Finally, close the phone only after the display reacts in a steady and predictable way.
