    Diagnostic Hardware Specs: iPhone 16 Pro Max | OS Version: iOS 18.1 | Archive Source: Apple Support Community #256389073

    I am running into a persistent issue on my iPhone 16 Pro Max 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 0xe058 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?

    Tuning force pressure settings to Firmer and changing launch trigger from Single Click to Double Click.

    Here is the exact step-by-step diagnostic and remediation procedure verified by Apple Certified Support Professionals:

    1. Go to Settings > Accessibility > Camera Control. Change Pressure and Light Press Sensitivity to Firmer.
    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.
