Motorola says the Signature 27 will be its first device to support GrapheneOS, a hardened, open-source operating system based on the Android Open Source Project. The company developed the device in partnership with the GrapheneOS Foundation.

Motorola says the phone is built to meet GrapheneOS requirements for hardware and updates. It also says the Signature 27 is its first device with a performant implementation of ARM Memory Tagging Extension. Motorola plans to share more details on that implementation in the coming months.
