CaptainKneedeep Welcome! GrapheneOS only works on Pixels. See here for the supported devices: https://grapheneos.org/faq#supported-devices
CaptainKneedeep use my Iphone as an underwater camera in a housing which uses the default icons on the lock screen to open and use the camera. Anyone know if GOS uses the same areas?
If your underwater housing is specific to iPhone's theb you won't be able to put a Google Pixel camera inside it.
GrapheneOS does have similar lockscreen shortcuts on the bottom left and right that you can interchange with different options (camera, flashlight, Mute/Silent mode, etc.)
There's also a feature (not enabled by default) that allows you to quickly access the camera from the lockscreen by double tapping the lock button.
