I believe Android made tweaks to the access system at 4.4 (causing thousands of apps to stop functioning), 5, and 6. There are a lot of subtleties. Like *apps* should be able to use the external drive for private activities, even if the card hasn't been formatted for private use. But your other apps won't be able to access that space, except through your own application.
When they say they're concerned about "security", what they're really trying to secure is *you*. Forget about hackers, what they really want is to secure the system for DRM. When everything is served through custom apps, it becomes much harder to offload or bootleg content. The upshot is that they also want to wean us off the idea of "files". Internally, everything needs to be handled through content "providers", rather than simple files. In the future, there will be no more files, only services from which videos can be played, music can be listened, documents can be written, or books read. My understanding, such as it is, is that something similar is happening with the Apple devices, so if you want to plug in an external device, you also have to run an app that can serve specific content (videos, images, music) from those devices. -- Mark On Wednesday, January 16, 2019 at 4:12:41 AM UTC-8, @TiddlyTweeter wrote: > > Mark S. wrote: >> >> >> Re reports, at the moment, for saving I'm interested in: >> >> * Were you saving to internal or external drive? >> > > Footnote about this ... in my understanding initially Android allowed full > access to save anywhere on the phone.
