I have a very close friend that works for the clandestine service, Mussolini. He tells me that they have backdoors into all cellphones that exist. I didn't believe him at first but looking at the recent vault 7 leaks[0], now I am not doubting him.

EDIT: Also it's not hacking/breaking in when it's a built in backdoor.
