Android/Google does not fulfill the spirit of that. Yes it’s technically Linux, but it’s not what one expects from a Linux experience. We all know this, we all know Linux is under the hood, but “Linux phone” is basically shorthand for more user control, more open source aspects, more secure/private, and far away from companies like Google/apple/etc. Android phones do not fill that request even with graphene and such. Google still has too much control.
