Would like to suggest a possible need to the dev wizards on HN, and also request pointers to something good that may already be out there: I would like a phone app that would disable anything that a user doesn't actually need (not something like the existing google android feature that identifies apps that haven't been used in x months). It may ask a user what they actually need (for example, calling, SMS, a browser, etc.). The app would identify all the software/apps on the phone that are not required for the above needs and identify / disable them (say for example Location services). When you get a new phone one could start off with an absolute minimum. It would need ongoing updates, as the app universe and surveillance technologies continuously evolve.
