When I first installed GrapheneOS, F-Droid gave me the option install Google Play. Later, I found out Aurora Store exists, installed it, them uninstalled Google Play. I found out many apps don't work without Google Play, so I need to reinstall it, but the initial way I installed it isn't available anymore.

    qll-the-struubl Hey there~ I think you may be confusing something, because F-Droid is not bundled into GrapheneOS and it definitely doesn't house any Google Play apps.

    What you're probably referring to is GrapheneOS' "Apps" app.

    To install Sandboxed Google Play, do the following:

    1. Swipe up to open your app drawer
    2. You will see an app called "Apps". Tap on that.
    3. You will see Google Play Services there, along with 3 other apps (Auditor, PDF Viewer and Camera).
    4. Tap on Google Play Services and install them. :)
