General, unbreakable crypto security applied to all contents is a feature that very few people ever needed or even tried to achieve.

Until a few years ago you were perfectly content with keeping an agenda in your pocket and pictures in your living room's drawer. A minimum of privacy is of course needed and welcome; however, unless you're planning a major terror attack, or strategic war plans, or you have incredibly valuable industrial secrets (all cases in which you'll probably be using specialized SW to keep your information) you don't really need incredibly advanced security simply because nobody is going to spend vast amounts of time and resources to uncover your little secrets. The GP is talking about switching phone (spending money) to obtain a level of security that he won't need in a million years.
