Now that CopperheadOS has launched on the Nexus 6P I have had a chance to test it out. Rather than continue on with this discussion in the Guardian Rom thread I think CopperheadOS has earned its own thread. The first release of the 6P Rom was on the weekend and all I can say is that I am impressed. I have used other ROMs on the Nexus 6P but they all have two key faults. 1.) Few ROMS are designed to operate without Google services (from message pushing through to Google Play) 2.)Security from the ground up CopperheadOS is rock stable and the battery life is fantastic. I have not got to the bottom of the security settings yet but am impressed. If you really are interested in a security focused Android build I strongly recommend it. If you like it make sure you support the developers.
