    Diagnostic Hardware Specs: iPhone 16 Plus | OS Version: iOS 18.0.1 | Archive Source: Apple Support Community #256701639

    I am running into a persistent issue on my iPhone 16 Plus running iOS 18.0.1.
    Whenever the machine encounters Capacitive sensor threshold over-sensitivity in one-handed grip, the following diagnostic log appears in Console:

    CoreMotion: [CameraControl] Pressure register 0xb331 registered threshold exceedance in portrait hold

    I verified that hardware connections are intact and tested across different power sources. What is the verified diagnostic procedure to permanently eliminate this symptom?
