iPhone 16 running on 18.0.1 runs into Kernel Panics, happened 2 times since I bought the phone.
My iPhone 16, has run in Kernel Panics 2 times in the last few weeks since I bought the phone, I checked the system analytics in the phone and noticed 2 panic files, then I did some digging into these .ips files with AI I found out this,
Summary of the Issue:
The panic was triggered by a component called EXBrightComponent (likely related to screen brightness) during its initialization. The error message "[EXBright] Invalid input (start=1120618203827 end=1120618151936)!" indicates that the component received incorrect time values (start time being after end time), leading to the fatal error.
What Happened:
- Invalid Time Input: The EXBrightComponent, responsible for managing screen brightness, was being initialized. It received two time values, a start time and an end time, that were logically inconsistent. The start time was actually after the end time.
- Fatal Error: This invalid input caused a fatal error within the EXBrightComponent. The component couldn't proceed with its initialization because the fundamental logic of its operation was violated.
- Kernel Panic: Because this error occurred within a low-level system component (an "exclave" component, meaning it runs in a somewhat isolated area for security), the entire operating system was affected. The kernel (the core of iOS) detected this unrecoverable error and initiated a panic, causing the phone to crash and reboot.
Key Details from the Log:
- Bug Type 210: This is the general code for kernel panics.
- iPhone OS 18.0.1 (22A3370): The specific iOS version running on your phone. This is helpful for Apple in diagnosing the issue.
- Exclaves: These are isolated memory regions where certain system components run to enhance security.
- Invalid input (start=..., end=...): The root cause of the panic – incorrect time values being passed to the brightness component.
- SecureRTBuddyProxy: A kernel extension related to display brightness and display control that appears in the backtrace. This extension might be involved, although the primary issue originates from EXBrightComponent.
- EXBrightKext: Another kernel extension related to display brightness.
What to Do:
- Software Update: Ensure your iPhone is running the latest version of iOS. Updating often fixes bugs, and Apple might have already addressed this one.
- Monitor for Recurrence: If the panic happens again, especially under similar circumstances (e.g., adjusting brightness), it indicates a persistent software issue.
- Contact Apple Support: If the problem continues, contact Apple Support. The panic log provides valuable information they can use to diagnose and resolve the issue. They might suggest a restore as a next step.
Now I've updated my iPhone to 18.1, my concern here is that even though this seems to be a software related issue I didn't find any details related to this in apples iOS 18.1's bug fixes page, so I'm worried this might be a hardware issue if it is then I need suggestions to what to do next? do I go back to the store and demand a new piece? what are my options here? I am a dev too, so this clearly does seem like a software related issue, but I'm no expert. Please help out any suggestions are welcome. I'm a little sceptical to attach the entire .ips file not sure if it contains any PII information, its a pretty huge file. I hope the summary helps though.
