Does ice work on a locked phone?

Does ice really have any effect on a locked phone? I've heard some rumors that applying ice to a phone's screen can somehow unlock it, but it sounds a bit too outlandish to be true. Is there any scientific basis behind this supposed hack, or is it just another internet hoax? If it does work, how does the ice interact with the phone's mechanism to unlock it? I'm genuinely curious about this, and I'd like to know if there's any legitimacy to this supposed method of bypassing phone locks.
