I am running into a persistent issue on my iPhone 16 Pro Max 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 0xb3c9 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?
