Same. Got the P2 because it'll be updated. With KRACK and BlueBorn and all sorts of nasty exploits out there, waiting on another party pretty much meant not being able to use my phone at all. I moved to a P2 from an unlocked S7 which is apparently back on a quarterly update and still doesn't have the BlueBorn patch, which is par for the course from Samsung. They only seem to patch their latest phones, and only for a few months before they drop the ball again.
I kinda feel like the P2 is a downgrade from the S7. No microsd, no wireless charging. But right now security is such a big issue maybe it's worth it.
