HOW TO Unlock On/Off Icons for Toggle Switches on Your iPhone

Apple's iOS doesn't have the best reputation when it comes to customization, but with every new iOS version we get, there are more options to personalize. Your iPhone comes packed with plenty of tweaks and hacks to make the device feel truly yours, and one of those is a fun yet useful mod that adds on and off icons for toggle switches on your iPhone.

In iOS 13 or higher, activating these icons couldn't be simpler.
Head to Settings –> Accessibility –> Display & Text Size, then tap the toggle next to "On/Off Labels." Now, your enabled toggles will sport an "I" or "1," depending on your interpretation, while disabled toggles will show an "O" or "0." This setting applies to all toggle switches throughout the Settings app, but it also applies to preferences throughout supported apps as well.

While these icons don't really do anything, they serve two purposes. First, they add another visual cue to know whether a setting is on or off. In Apple's human interface guidelines, it states that "the addition of labels makes it easier to perceive whether a switch is on or off." Second, it serves as a fun aesthetic choice for your toggles.
