Here’s just one problem caused by overloading the iPhone’s home button. Let’s say I’m in Safari, and I want to launch another app. Most of the time, the app I want to use is on the first home screen. How do I get from Safari to the first home screen? In earlier versions of iOS, it used to be simple. To get to the first1 home screen, hit the home button.
That’s not how it works anymore. If I want to go to the first home screen in iOS 4,2 it’s more likely to play out like this:
In some cases, you’ll have to hit home fewer times. In others,3 more.
You can’t even resort to just hitting the home button blindly a bunch of times, because if you hit it too rapidly, the iPhone will interpret it as a double-tap. Besides, you don’t know how often to hit it; if you hit it too often, you’ll jump into the «Search iPhone» screen. For example, if you’ve previously launched another app from the first home screen,4 the whole process looks very similar to what I’ve shown above, but the same number of home button taps now brings you to the search screen:
It’s a constant game of «are we there yet?» «No.» «Are we there yet?» «No». «Are we there yet?» …
This isn’t a hypothetical example. This is something I do probably a dozen times a day, and every time, it causes me a tiny bit of frustration because I’m doing more work (and I’m being forced to think more) than I should be.
What’s the Point of Remembering the Home Screens’ State?
It’s not clear to me why Apple does this at all. If I launch an app from the fifth home screen, is it highly likely that the next app I want to launch is also on that home screen? If I launch an app from inside a folder, is it highly likely that the next app I want to launch is also inside that folder? Probably not. So why not just send me to the first home screen when I hit home? That way, I always know where I end up when I hit «home».
Need something from the first home screen? Hit home. Need something from the second home screen? Hit home, swipe once. Third? Hit home, swipe twice. Want to search? Hit home, swipe once. You don’t have to wait and see where the home button brings you; you can do it blindly. You know what the result of every interaction will be before you do it. Never a miscommunication. Your iPhone is predictable again.
