Unfortunately I need my electronic ID that only runs on Windows, Apple, iOS and the Google Android unless you can spoof it. Not even regular Linux or with Wine. And I use it near daily.

Boo Sweden.

Boo EU.

Would Android running in an LXC conatiner suffice? That’s what SailfishOS offers, and many users report their ID apps working that way, also Swedes.

Not sure what you mean.

I wonder how hard it’d be to flash android on a pi zero or similar to display only the ID forever. I’d never put something like that on my phone.

You could just install Waydroid. It’s recently become part of the Debian repos and supports armhf.

It should run fine with a fast microSD and nothing else running, considering the Pi Zero is a slow device.
