iOS Text String Bug: A Few Characters Can Crash iPhone

A report highlights an iOS quirk where typing a four-character sequence (two double quotes followed by two colons) in Spotlight or the App Library can cause a brief soft reboot on iOS 17 and sometimes a short freeze on iOS 18/18.1. The issue is not remotely exploitable, is not deemed a security vulnerability, and appears user-triggered only; Apple is expected to address it in future updates, though users should be wary of prank prompts encouraging the input.
