You’ll see hex dumps, register states, and thread backtraces. It looks like a robot having a stroke. But we only care about one specific line: In simple terms, a kernel panic is iOS’s
Have a panic log you can’t crack? Drop the PanicString in the comments—I’ll translate it for you.
If your iPhone crashes randomly twice a week or more, you likely have a hardware problem. If it happens once a month, it’s probably a software bug.
