Security is a major consideration for us so I'm looking for the most secure off the shelf solution for this. I'd like to encrypt all data on the phone and use encryption for txt and phone calls. There are a number of apps in the android market that claim to do this but how can I trust them? For example, I tested one but it requires a lot of permissions such as internet access, how do I know it is not actually some kind of backdoor? I know that Boeing is producing a secure phone which is no doubt good but probably too expensive for us. I was thinking of maybe installing Cyanogenmod onto something, using a permissions management app to try and lock down some backdoors and searching out a trustworthy text and phone encryption app. Any good ideas out there?
