Shade how would you install the orignal version without Google play store?
Use Aurora Store. However i must say that safest download method is through Play Store.
Shade remove google connection then give it to people as apk they even do it for none pixel phones
Not all of them revoke the network permission. GCam modders try to bring the features of Pixel Camera to other devices and don't necessarily care about privacy or security.
Plus some official Google Apps, including Pixel Camera, are benefiting from hardware acceleration on GrapheneOS.
Modded versions change the name of the app to avoid conflicting with the official one, thus not benefiting from hardware acceleration because they are not recognized by the system as the official one does (someone correct me if I'm wrong).
Shade why didn't Graphene brought Google's camera app
I think it's not open sourced, so it can't be shipped with GrapheneOS.
