You're a cynical one. So you think I decided to make up a story, login to UKP, type it up and post it.
I am cynical, because I have seen it happen so many times over the years.
I think maybe something happened which frightened you enough to trigger posting a warning story, but not the exact one you describe, as there are inconsistencies some of which others have pointed out.
The main one being that your daughters phone could have just remained locked. Once you unlocked it that surely raises more questions than leaving it locked? How did you explain why had you set up a new code on your daughters old phone and charged it up and which had been lying in a phone graveyard? It seems fortuitous you had some kind of premonition in the days before that your wife was about to discover it? If so why wipe it clean and put it back in the phone collection charged up with a sim in it. Just bin it like a burner. Its all overly complex.
But hey it doesn't matter most seem to accept it as accurate so all is well.
