Someone is making encrypted Android phones in Switzerland, they said they would cost about $600.00, and should be shipping by now. They can interoperate with regular Android phones if those phones have their app installed. I don't know what happens, if one calls a phone that does not support encryption. Boeing is, or will soon be making such a phone, specifically intended for classified communication. I don't know whether they will be sold to the public.
