How can I installer the Google dialer (phone app) on any phone without root? I want Google's Dialer phone app on my Nextbit Robin running Android 6.0.1 Marshmallow but without using root.

It's an official APK Google released by mistake that does not limit which phone it can be installed on. Unlike the other versions that can only be installed on Nexus phones.
