First install GrapheneOS

ErminioOttone

Hello to everyone, I just installed for the first GOS on my phone. I am noticing that at each restart there is an initial message saying " hey this phone is not running the stock OS " and then it boot fine. My question is, does everyone has this initial message from the system during the restart or just the start of the phone ?
Thanks :)

ErminioOttone Yes it's normal and only means that GrapheneOS is not verified by Google which is why you see the warning. It is shown at every restart.

ErminioOttone Hello and welcome.

Yes don't worry, it's normal and this is expected behavior.

Yellow : Means you're using another operating system and the boot loader is locked (perfect)
Orange : Means you're using another operating system but the boot loader is unlocled (to correct)
Red : The OS is compromised and cannot be trusted (critical)
