I'm not sure why did I got this "2016 flagship killer" Oneplus 2 that's still running Lollipop anymore, maybe it's time to "upgrade" to a 2014 flagship Samsung Galaxy S5 running Marshmallow. Hopefully the update will be ready before Android N becomes outdated.
Before anyone says "community build", it is what it is, a community build, i.e. not final. And it's been a month since the community build is out and it's still not ready.
