Make sure that the phone we sent you has the correct Graphene OS version.
You can use the Auditor APP that comes with Graphene OS to make sure that the OS version we installed on your phone is the original one without any modifications (Please note that unfortunately the Auditor APP no longer supports CalyxOS).
For more information about the APP, please follow this link https://attestation.app/about. In short the Auditor APP
"uses hardware-based security features to validate the identity of a device along with authenticity and integrity of the operating system. It will verify that the device is running the stock operating system with the bootloader locked and that no tampering with the operating system has occurred."
Use the APP already installed on your phone (or redownload it from Aurora store or any other APP store of your preference) and follow the steps indicated.
We made a very small tutorial in the video below. The phone on the left is our Google Pixel 4A with Graphene OS installed. The phone used as Auditor in the video is a Huawei.
Any device with Android 8.0 or later can run the Auditor app and use it to verify other devices. However, only devices launched with Android 8.0 or later have the necessary hardware support for being verified. Each device model also needs to be explicitly integrated into the app. The following devices are currently supported by the most recent stable release:
