As I've got a stack of otherwise-useless old iPads lying around, I'd like to use them for signage: load a web page playing an MP4, don't let the user click on anything. "Guided Access" sounds like it is made for this, but I keep coming back a day or two later and the screen is blanked. It's on wall power and battery is at 100%. Any ideas?
Also you can't hide the Safari title bar, which is slightly annoying. There are a ton of "digital signage" apps out there on the app store, but that's a spam-heavy SEO-poisoned concept to search for so I can't tell if any of them actually do anything that I care about that "Safari displaying a web page" doesn't already do.
