Why does my Marshmallow Note5 have Nougat features?

[AC Question]

I have a dual SIM HK version of the Note5 with firmware 6.0.1. Ive been reading about the upcoming Nougat update, but it seems my phone already has most of the new features.

For example, i already have the new pulldown notification menu, the blue light filter, the battery monitoring/extending feature, and the multi window update, all of which should only have arrived with Android N.

So does anybody have any ideas on why my phone has these updates, but not all, while still running Marshmallow? Id be very appreciative of any thoughts on the subject.

IIRC Those features were in the Marshmallow release of the Note 7, which made their way to the Note 5 after its demise. They're not Nougat-specific.

These are in fact part of the Grace UX addition to Marshmallow 6.0.1 that Samsung did.. With Grace UX, some of the Nougat features were added ahead of the Nougat release. See also https://www.sammobile.com/2016/11/2...-update-for-the-galaxy-note-5-in-south-korea/
