Amidst the plethora of pricey gadgets and services susceptible to security breaches, it's a breath of fresh air to stumble upon a genuinely entertaining and seemingly harmless iPhone quirk.
Uncovered by security expert Konstantin on Mastodon (and corroborated by TechCrunch), typing the sequence “”:: (two quotation marks followed by two colons) into specific iPhone text fields can trigger a temporary freeze. TechCrunch confirmed that this phenomenon occurs when searching within the Settings app or browsing through the app library; I won't be putting this to the test personally and wouldn't advise others to do so either.
Notably, this glitch doesn't appear to pose a security risk – and it's unlikely to cause lasting damage to affected devices. Furthermore, it's easily avoidable, as the specific character sequence is more akin to something a young child (or a disoriented adult who's just woken up) might accidentally type into their phone.
