The Punkt MC02 phone doesn't run GrapheneOS. It still runs a fork of Android 13 while #GrapheneOS is solely based on Android 15. MC02 is clearly using the LineageOS update client, not the GrapheneOS update client. It's problematic that some people think it's a way to get GrapheneOS.

MC02 appears to use an older version of our sandboxed Google Play compatibility layer, but they haven't kept up with our updates at all so they don't have the full app compatibility of GrapheneOS. We're unsure how much other code they used from GrapheneOS but it's not current.

There are many companies selling devices with GrapheneOS preinstalled. It's also very easy to install it on your own with https://grapheneos.org/install/web from a web browser on another device. MC02 isn't a way to obtain GrapheneOS preinstalled and GrapheneOS can't be installed onto it.

There's a lot of media coverage about the device including reviews where it's portrayed as running GrapheneOS. We weren't contacted by news publications about their stories/reviews. We would have been happy to correct misconceptions if we have been contacted about any of this.
