Until a few years ago I was using Blackberry OS 10, which allowed for getting a backup image of the phone through USB (backing up literally everything). It also had "securely wipe device" functionality (or something along those lines) to make sure restoring files after a whipe was impossible/harder. I'm still blown away by the fact that (unrooted) Android does not offer such basic functionality. Even many years later. And by the fact that Android is spyware by design, but thats another discussion. According to another comment here Iphone also has similar backup features to BBOS10. Conclusion: don't buy an Android phone and do as describe in parent post?
