This is incredibly strange, and I just want to see if anyone else has noticed this. One of our phones was sitting on a table, not even remotely touching anything. It hadn't been used for at least 30 minutes or so. Out of nowhere, it woke up and unlocked to the home screen. It is an iPhone 6S Plus with Touch ID enabled, so I'm wondering if maybe 9.3.2 introduced a glitch with the Touch ID sensor. In any case, this was pretty disconcerting.
