@topcaser Nearly all regressions are upstream regressions since that's most of the code and we're very careful with our changes. Most of the regressions specific to GrapheneOS have to do with porting to new Android releases, so it's the upstream code changes causing issues either due to needing changes to our device support code or the features we add / changes we make. We have a lot of our own code but it's not changing much beyond porting to new releases. We slowly add new stuff.
