One note on the phones thing: some camera apps (on Android, dunno about iOS) provide additional settings. For example, the Samsung stock camera has a "pro" mode, which lets you adjust the white balance, exposure, metering, and "ISO". Third party apps will provide histograms, long exposure, time stamps, etc. It's all similar to how many people used disposable film cameras (no options except aim and push the capture button) or cheap reusable cams (zoom, maybe exposure, etc) but film cameras that let you adjust everything existed at the same time
