    Diagnostic Hardware Specs: iPhone 16 Plus | OS Version: iOS 18.1 | Archive Source: Apple Support Community #256844648

    I am running into a persistent issue on my iPhone 16 Plus running iOS 18.1.
    Whenever the machine encounters Capacitive sensor threshold over-sensitivity in one-handed grip, the following diagnostic log appears in Console:

    CoreMotion: [CameraControl] Pressure register 0x62e1 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?

    2. In Settings > Camera > Camera Control, change Launch Camera to Double Click.
    3. Disable swipe gesture adjustments if exposure sliding is not required.

    Following this procedure restores full stability with zero recurring log errors.
