The Motorola Signature 27 will be the first non-Pixel phone to officially support GrapheneOS, according to confirmation from the privacy-focused Android project reported by Android Authority and other outlets. Until now, users wanting the security-hardened operating system had to rely exclusively on Google Pixel hardware, as software and security components in Pixel devices and Tensor chips uniquely matched the project’s requirements.
Motorola Signature 27 Hardware Specs and GrapheneOS Requirements
GrapheneOS creators confirmed the U.S.-bound Motorola Signature 27 will run the platform in a reply to an X user, though exact release timing remains unconfirmed. The high-end flagship was announced earlier in the week and will feature Qualcomm’s Snapdragon 8 Elite Extreme Gen 6 chip. According to coverage from Tbreak, GrapheneOS pointed to hardware memory tagging, stronger secure-element integration, and long-term software support as necessary prerequisites for its first Motorola devices. Motorola has promised seven Android upgrades and seven years of security updates for the phone.

Pre-Installed Software Versus User Installation Plans
While the Motorola Signature 27 is first in line for support, the project has previously stated plans to sell devices with GrapheneOS pre-installed, alongside allowing buyers to purchase standard retail variants and flash the software themselves. Neither Motorola nor GrapheneOS has confirmed which distribution route the Signature 27 will use. Future versions of Motorola’s Razr flip and Razr Fold devices are also expected to support the operating system.

Pro Tip: GrapheneOS restricts standard Android app permissions and allows users to block all networking on a per-app basis. Because it is based on the Android Open Source Project (AOSP), it omits proprietary Google apps and relies instead on third-party app stores like F-Droid.
