Am I wrong (again) but I thought with today's smart phones and most of them having fixed batteries, ie - one's you can't simply open the mobile's case and remove the battery, I was under the impression that with the right software, for certain organizations / people, it is possible to use your mobile phones GPS to locate you or your mobile, any time day or night 24 / 7.
Not only your track GPS location but same as your PC, laptop, etc. remotely turn on your webcam as well without you knowing or being able to do anything about it.
See --> George Orwell's novel Nineteen Eighty-Four. - - - he might have got the year wrong - BUT, just in case - - - - - -
