“Hey Siri, I just” causes an infinite loop!
Just found this today on my Apple Watch. Maybe everyone already knows about it.
If you say, “Hey Siri, I just”, Siri responds with, “I don’t know what you mean by, ‘Hey Siri, I just'”. Siri then hears itself saying “Hey Siri, I just” and responds again with the same message, forever, until you press the button to stop it.
Kind of neat.
Edit: mine is an Apple Watch 3, watchOS 6.1
Edit 2: *Hey Siri, I just caused an infinite loop* also works!
