userofgos silverhand IndigoMizumi See here for an official source: https://xcancel.com/GrapheneOS/status/2065150023621312769#m It's the 2027 and later Motorola flagships which will be supported by GrapheneOS. Support for lower end devices is planned but will require updates and security features to trickle down to those. The initially supported ones will be higher end and more expensive than Pixels.
Johnnyloans silverhand I heard the 2027 signature and razr, but there are multiple razrs so 1 or more of those.
