There is no way this thing is %100 open source. Last time I built a full AOSP from scratch, I found out: - VoLTE and SMS over LTE is a proprietary library. - WiFi calling is a proprietary library. - the Vendor partition is entirely proprietary, and at least for the Pixel, is different depending on if you use the AOSP version or the stock Google Version. - For the Pixel 3a, you cannot even POST the phone without adding a proprietary library! I would be shocked if it's different for the Pixel 4. I know for a fact that you cannot even boot a Pixel 3a without adding proprietary libraries.

In my opinion, if Nitrokey was at all serious about making this 100% open source and secure, they would help mainline the kernel for it.
