I didn't know that. I thought Tips was an app that gave you a couple of dozens of tips, and nothing else.
Would naming it "User Manual" be any better?
That’s why they’ve never read the manual.
I tried to find the answer to a problem I had and it's not there. I inherited an iphone where the side ringer mute toggle bounces back after setting, it's a mechanical error. There is no software "unmute" override - unless you use assistive touch. It took quote a while of wading through google results and well-intentioned-but-clueless advice from people before I found someone who revealed this. The manual just says assistive touch can help adjust volume so it is technically true I guess but the keyword "mute" is not there.
I did learn about the triple-click shortcut from than online manual just now, so I should thank it for that (even though it neglects to mention it needs to be enabled first).
The manual is also available as an 843-page ebook [2], and is accessible via the Tips app, which is preinstalled on the home screen.
It's not quite like the days when a paper manual would be right in the box, but it's close. And I think most people would be unhappy if their sleek new phone came with an 843-page tome (not to mention how much paper that would waste).
