Motorola has announced the Signature 27, a $1,599 flagship phone that will go on sale on November 26, specifically designed to support GrapheneOS, a hardened Android-based operating system. Developed in collaboration with the GrapheneOS Foundation, the phone features a 6.8-inch AMOLED display, Snapdragon 8 Elite Extreme Gen 6 chip, up to 16 GB of RAM, and a 7,000 mAh battery with 90 W wired charging. Although the phone is built for GrapheneOS, it's unclear when the operating system will be available for it or if it will come pre-installed. Motorola promises seven years of Android OS upgrades, making the Signature 27 an attractive option for those seeking a secure and long-lasting device, particularly with its potential to move beyond traditional Pixel support for GrapheneOS.
