I installed GrapheneOS on Pixel 7 and the sandboxed play services. As I noticed in Play store, the Play Protect certification has the status "Device is not certified".
I thougt I can get the certification state by registration at Google. So afterwards I registered my device, technically the Google Play Service Framework ID (GSF), on www.google.com/android/uncertified website.
Found out the Framework ID (GSF) with this App: https://www.apkmirror.com/apk/evozi/device-id/
After this I forced the stop of Play Store, cleared the cache and storage of app "Google Play Store".
I would have expected the Play Store to be in a certified state now, unfortunately it is not. Should the certification registration work with GrapheneOS? Or is the Framework ID (GSF) maybe an another one because of the sandbox layer?
