The iPhone’s home button is responsible for at least six different default functions—waking the lock screen, opening the multitasking interface, scanning Touch ID, summoning Siri, triggering Reachability, and going to the home screen. Objectively, that’s a lot to ask of one single button.
With all of this stuff going on, you’ll sometimes encounter situations where you didn’t mean to trigger a certain function. Other times, you’ll double-click or triple-click, but the action you were trying to perform isn’t registered. To help get things under control once and for all, or to get even more functionality out of your home button, check out the tips below.
If you’d like to disable this feature, start by heading to the General menu in your iPhone’s main Settings. From here, tap the Accessibility entry, then scroll down a bit and toggle the switch next to Reachability. From now on, double-tapping your home button won’t cause anything to happen.
2. Decrease Click Speed
For double- and triple-click functions, there’s a certain speed that these gestures need to be performed with, otherwise the multitasking interface or your accessibility shortcut won’t be launched. For some people, the default speed between clicks might be too fast.
If you’d like to change this, head to the same Accessibility menu in Settings under General. From here, scroll down a bit, then select the Home Button option. Next, set the Click Speed to either Slow or Slowest, and from now on, you can take a little more time between button presses when launching double- and triple-click gestures.
3- Disable Siri to Prevent Accidental Triggering
How to Disable Siri Altogether
Don’t find Siri all that useful? You can disable her altogether—not just on the lock screen. Just note that this will NOT help you when accidentally long-pressing the home button in your pocket, because Siri’s backup, Voice Control, will activate instead, and there’s no way to disable Voice Control.
If you still want to disable Siri altogether and use Voice Control instead, head to the General menu in Settings, then select the Siri option. From here, turn the feature off using the switch at the top of the screen, then press “Turn Off Siri” when prompted.
Up until this point, I’ve only covered tips that involve removing or slowing down home button functionality for the sake of simplifying things. But you can actually add functionality to this button by assigning a triple-click gesture. Unlike Siri and Reachability, it’s quite hard to trigger accidentally, so it’s something you may want to consider.
This even works with multiple accessibility shortcuts enabled, in which case you’ll be prompted to choose an action after triple-clicking.
If you’re still not happy with your iPhone’s home button, or if it’s currently broken or buggy, you may want to try an entirely new way to interact with your device. Instead of using a mechanical button to do everything, a feature called AssistiveTouch lets you control your iPhone with on-screen buttons.
To enable this option, start by heading to the “AssistiveTouch” entry in your iPhone’s Accessibility menu. Use the toggle up top to enable the feature, then a small, semi-transparent button will appear. Tap this button, and it will expand to show several more controls like Home, Siri, and Control Center. Even better, you can add or remove actions from this pop-up menu by using the “Customize Top Level Menu” option in the AssistiveTouch settings menu.
