Unresponsive iPhone 4 Home Button

The iPhone’s home button had been rather unresponsive for a month or two. On standby mode, when I press it sometimes it takes some time before the screen lights up. Sometimes it doesn’t at all and I have to press it again, harder. The same unresponsiveness happens when I try to exit out of an application or try to launch the fast app switcher.

At first, I thought it’s just dust and lint so I blasted air through the available openings in the hope of dislodging any that may have accumulated. That didn’t work at all. I was starting to fear that I need to have the button replaced. But today, I found a possible solution here and here:

  1. Open a built-in application
  2. Press and hold the power button until the slide to shutdown swipe bar appears.
  3. Release the power button
  4. Press and hold the home button lightly until screen returns to icon screen

It does seem to work at first, but probably psychological, because soon it seems the button was back to its old unresponsive ways.

So I kept looking and I found one that does make sense here. I have my Accessibility triple-click Home button setting enabled. I figure that with this enabled, the OS will wait just a millisecond more to see if there’s an upcoming third click before responding. Turning off triple click improved responsiveness. Now how to shorten the double-click wait…
