You are using GrapheneOS on a compatible device

A free operating system is always the right choice if you want to be independent of large corporations such as Google or Apple. However, an operating system called GrapheneOS stands out with its numerous security features and is therefore highly recommended for activist purposes. For example, Graphene supports an LTE-only mode that can prevent various attacks on the mobile network. You can also deactivate all of the smartphone's sensors. GrapheneOS only supports a few devices. You can find out what these are and what else it can do on the GrapheneOS website.
