I see some core team on this thread, so just wanted to say THANK YOU! Awesome job! Keep fighting for the users!
I'm totally the wrong person to offer recommendations on mobile, but so far it works very well for me, but then, I use almost no third party apps, and none of them are Play store only. My only complaint is the hardware (outside of their control).
I wish that were true, but if you delete the 100s of binary blobs (many with effectively root access) copied from a stock donor vendor partition the phone won't function at all.
There is no such thing as a fully open source and user controlled Android device today.
It would be nice if the firmware itself was free software so that it could be shipped alongside the Linux kernel, maintained indefinitely and we could customize it however we want. The hardware is supposed to do what we want it to do, not what the manufacturer lets us do.
I don't like the fact every single device out there has entirely separate computers inside them running unknown proprietary software. It feels like our operating systems aren't operating the system anymore, it's like they're just some user app sandboxed away from the real system. This presentation explains what I mean:
It's an imperfect reality. Security by isolation of devices via IOMMU addresses real concerns such as devices being able to access RAM via DMA. It's great that GrapheneOS is doing this.
