And let me add that coming to market with a new product in a mature industry is incredibly hard.
I can't see this succeed, only the die hard linux geeks will try it out. Just look at the forums, and even the videos posted on pine64.org. They're more interested in you trying to load many different distros on the phone instead of providing a polished distro that has all the basic and required apps that a phone needs in 2021. You know, texting, social media apps, games etc. They seem more focused on showing people they actually can run fedora on a phone then trying to provide a full solution. At least System76 did that right with Pop_OS
Also as I mentioned, Android, is open source, and there are custom roms available (provided you have a phone you can root). I think you'd be better off using a custom rom and use all of androids tried and true services and apps.
Let me just add the LTT video that pine64 linked too basically said its not a daily driver phone but rather for those on linux who want to play with it.
