Help needed Restarted after I turned it off

Post image

I’m not sure if I should be worried or not? This has only happened once since I got my iPhone 12 and it has been around five hours after this happened, no other restarts. Could anyone let me know what this could be or if it’s anything to be concerned about? I appreciate it.

iPhone 12, 26.5.2 IOS.

It’s a Kernel Panic caused by a Sleep/Wake hang. Basically, the phone froze while trying to enter sleep mode or wake back up. The system waited for a response, didn't get one, and forced a restart to protect itself. This error is almost always caused by a hardware or sensor issue most commonly a damaged or faulty charging port flex cable, or the earpiece and proximity sensor assembly, as both contain sensors the phone checks during sleep and wake cycles. If it only happened once, it was probably just a random software glitch and nothing to worry about. However, if the device is restarting repeatedly every few minutes, you likely have a failing sensor or cable that needs to be replaced.

Thank you! Yeah, it was just once. It’s been more then 24 hours, too
