Siri is responding to everyone
my siri is responding to everyone, whenever anyone says hey siri, the siri is responding and activated, i am really fed up with this bug
This is not a bug. It's by design. Siri is not limited to a single person's voice in any way.
There is no way to make Siri only respond to your voice if that is what you are thinking.
Siri merely responds to "Hey Siri", not a specific person's voice.
