Checkpoint software has released an app in the Play Store called Quadroot Scanner.
I'd installed and ran it and it said my device was not affected by this bug. My guess is that many/most/all of the Turbo 2's out there are the same but get the scanner and check for yourself for peace of mind if you need it.
I saw that someone posted about this so I decided to dig a little further. I would have posted this in that thread but for some reason the threas is locked...
