so I've changed a splintered display including a new flex-cable with front camera, brightness and proximity sensor of an iPhone 8 for my first time and it is working nearly as wanted... nearly!
The proximity sensor does not work anymore but everything else: The front camera, the display, the home button, the automatic setting of brightness and also the earpice is working without a problem. The sensor is plugged in its place and can "see" through the cut-out.
My question is: Is there any step missing? Do I (which I doubt) have to activate again because it is a new hardware component?
Thanks in advance!
