The Back of Your iPhone Has a Secret Button -- Here's What It Can Do
We're a few months out from the release of iOS 26, which will introduce a whole new look to the iPhone. But what if you're still holding on to an older iPhone that won't get the Liquid Glass redesign or Apple Intelligence for screenshots? What if you're itching to try out something new like the Camera Control button on the latest models?
Good news: There's a hidden feature that lets you quickly activate your iPhone camera without unlocking your device or touching the screen, and it works on some fairly old devices. All you need to do is set up the secret "button" on the back of your iPhone.

You can use this feature to not only launch your camera app, but also turn on your flashlight or activate Shazam to identify a song before it ends. You can summon your iPhone's Control Center or Notification Center without having to swipe down from the top of your screen. In fact, with a little bit of imagination, you can use this feature to perform almost any of your phone's functions.
The feature is called Back Tap, and like the Action Button on newer iPhones, it gives you one more way to interact with your device without touching the screen. You can activate it by tapping anywhere on the back of your phone, including on the camera module. And the best part is that it works even if you have a fairly thick case on your iPhone.
Back Tap is available on iPhones as old as iPhone 8, as long as they're running iOS 14 or later. We'll show you how to enable it and how to use it with your Shortcuts app for nearly endless possibilities.

What is the iPhone Back Tap feature?
Back Tap is an iPhone feature introduced in iOS 14. It lets you perform shortcuts on your iPhone by double or triple tapping on the back of the device.
You can customize Back Tap on your iPhone to easily perform common actions like pulling up the Control Center or Notification Center, especially useful if you have a larger phone and can't swipe down from the top of the screen without some complex finger gymnastics. You can even have two separate functions enabled at the same time: Back Tap can distinguish between a Double Tap and a Triple Tap.
Depending on the number of times you touch the back of your iPhone, you can set Double Tap to open your Notification Center and Triple Tap to take a screenshot. Or, you can make Double Tap open the Control Center and Triple Tap launch the Magnifier app. Experiment with Back Tap to find the right combinations of taps and functions that best fit your needs.
And you aren't just limited to the Back Tap options that are available by default. Thanks to the Shortcuts app, you can set up Back Tap to perform specific functions or launch any app. For example, you can create a simple shortcut that opens Shazam or starts a voice recording, then activate it with a quick Double Tap or Triple Tap. You can also use Back Tap to trigger a more elaborate shortcut, such as automatically sending photos and videos to specific photo albums.
How do I set up Back Tap on my iPhone?
To enable Back Tap, go to your Settings app. Then go to Accessibility → Touch → Back Tap. There, you'll find a list of options for configuring Double Tap and Triple Tap.
Here is the full list of functions that you can map to a Double Tap or Triple Tap:
None
Accessibility Shortcut
System
App Switcher
Camera
Control Center
Flashlight
Home
Lock Rotation
Lock Screen
Mute
Notification Center

Classic Invert
Color Filters
Control Nearby Devices
Dim Flashing Lights
Live Captions
Live Speech
Magnifier
Smart Invert
Speak Screen
VoiceOver
Zoom
Zoom Controller
Scroll Gestures
Scroll Down
Scroll Up
At the bottom of the menu, you'll also see a list of Shortcuts. These options will vary depending on what's available in your Shortcuts app.
The one potential downside to Back Tap is that you don't get any tactile feedback when you use it, so you might accidentally trigger it at the wrong time and not realize it until later. For instance, you might double tap without meaning to and set off your flashlight by accident. In that case, you might want to remap your Double Tap to a less conspicuous function. Or, you can leave Double Tap off and only use Triple Tap, which you probably won't trigger as often.
How do I use Back Tap to take a quick photo?
One way to set up Back Tap is to map Double Tap to the Camera and Triple Tap to Volume Up or Volume Down. Because you can press either of the volume buttons to instantly take a picture, you can get the same effect if your volume buttons are mapped to Back Tap. With this combination, you can capture a photo with five quick taps on the back of your iPhone (though you'll have to pause briefly between performing the Double Tap and Triple Tap, so that your phone can distinguish between the two actions).
This Back Tap combination even works if your phone is locked. Again, spend some time trying out different combinations of taps and features to find which ones are most useful for you.

iOS 26 Might Be Apple's Riskiest Redesign Yet
It's official, Apple's big software redesign is here, and all of your devices are about to look a lot different. At WWDC 2025 Apple unveiled 'Liquid Glass,' which is its own Apple way of saying, 'Your iPhone is getting a lot more bubbly.' The big visual overhaul changes the look of the UI inside Apple devices across the board, including your iPhone, MacBook, Apple Watch, and even your Apple TV 4K streaming box. And while the full gamut of Apple products is affected by the visual vibe shift, it's iOS that will probably catch the most attention—and for good reason. For one, lots and lots of people use iPhones in America, and even the slightest tweak to the UI can affect people on a mass scale. Secondly, from what I can tell without seeing the redesign for myself, iOS seems to be the most heavily impacted by the new design. I mean, seriously, check this out: Today, we're announcing our most beautiful software design change yet with Liquid Glass. And for the very first time, it's coming to iOS 26, iPadOS 26, macOS 26, watchOS 26, and tvOS 26 at once! — Greg Joswiak (@gregjoz) June 9, 2025 While Apple doesn't state it explicitly, the redesign seems to be heavily influenced by what some designers might call 'glassmorphism,' which is a visual style in UI that incorporates lots of opaque menus and, unlike Apple's current flat 'neumorphic' design, adds a bit of shape to icons that were previously kind of 2D. See (ironically) other operating systems from, *cough, cough* Microsoft, if you want another example of what glassmorphism might manifest as. Someone more knowledgeable than I could probably nerd out over the new look with a few thousand words, but a design maven I am not. When I look at Liquid Glass, I see things in a simpler light. I see mostly one thing: risk. On one hand, that risk is exciting. I think Apple's UI is due for an update. By Apple's own estimation, the last visual overhaul was way back in iOS 7, when iPhones still had a physical home button and 'Obamacare' was still a topic of political discussion. Not only that, but Apple, for good reason, has been accused a lot in recent years of not attempting to push the boundaries like it once did under the leadership of Steve Jobs and Jony Ive. A good way to show people you're not afraid to try something new is to, well, try something new. That's exactly what Apple did; it took a risk on a redesign that changes some pretty core elements of your iPhone's UI—icons, menus, you name it. But just like any bold new endeavor, there are going to be some tradeoffs. One of those tradeoffs, in this case, may be accessibility. As many of you have already noted, there are some visual quirks to Apple's glassmorphic era, and legibility may be at stake. As much as I actually like the look aesthetically of Apple's new Liquid Glass overhaul, I think there are going to be some big haters, and I can't exactly blame them. Having clear windows may look future-forward, but when that design encounters, say, I don't know, text on a page, things can get a little messy. What you get, at times, is a visually muddled menu that conflicts with other elements on a page. I'm not jumping to any conclusions yet since I haven't really seen the redesign for myself or how it interacts with web pages or apps, but objectively, it seems like there isn't as much contrast as Apple's previous look. One thing I've definitely noticed so far is that subtle differences in where a menu lands in an app or web page can make a huge impact. For instance, check out this picture. apple just introduced "Liquid Glass" design in iOS. it's beautiful, futuristic… and completely unreadable. what are we doing here? 😵💫 — Kalash (@amikalash) June 9, 2025 I don't know about you, but what I see is a blurry, visual disaster. But, if you check out the video this screenshot is pulled from, just a second makes all the difference. Here's the same visual demonstration, but the menu is offset just slightly on the text underneath. I feel like there's a pretty big difference in legibility here. It's not perfect by any means, and I certainly wouldn't call it accessible, but it looks a lot better. This is all to say that I think there will be subtle differences that determine whether you're seeing something clear, pleasing, and visually distinct or if you're looking at a garbled glassmorphic mess. From what I can tell, there will also be different Liquid Glass styles to choose from, which may affect the accessibility of menus. There's also the fact that this redesign doesn't officially launch until the fall, so anything could change. How you feel about Liquid Glass is obviously up for debate, but one thing is clear (pun intended), and that's that whatever Apple is doing with the iOS redesign and Liquid Glass writ large is definitely a bigger risk than past overhauls. To risk accessibility or legibility on a platform as big as iOS takes some real vision—whether good or bad. Let's just hope that the vision, for the sake of everyone out there with an iPhone, isn't quite as blurry or illegible as some of these early looks might suggest.

Apple unveils iOS 26 with Liquid Glass interface at its Worldwide Developers Conference
Apple kicked off its annual Worldwide Developers Conference on Monday with an array of announcements on new features coming this fall via iOS 26, its latest operating system upgrade. Leading the pack is a new user interface enhancement called Liquid Glass. CEO Tim Cook and other Apple executives used words like "beautiful," "gorgeous" and "delightful" to describe changes on the horizon for its devices. And while they emphasized a fresh user interface and elevated app features, they also reassured users that the tools would remain familiar and accessible. Read on for details on the latest bells and whistles coming to Apple's user interface. iOS 26, iPadOS 26, macOS Tahoe 26 Apple is adopting a new nomenclature for identifying its operating systems, one that is more straightforward than its previous numbering system. Rather than iOS 19, Apple's next iPhone iOS will be called iOS 26 to align with the upcoming year. iOS 26, along with iPadOS 26, macOS Tahoe 26, watchOS 26, and tvOS 261 are slated to be released as free updates in September 2025. Design upgrades, including Liquid Glass Alan Dye, Apple's vice president of human interface design, calls the new OS, the company's "broadest design update ever." A hallmark feature of the new OS is Liquid Glass, described by the company as an "expressive material" meant to mimic the qualities of glass. The dynamic new interface make apps, widgets and docs appear translucent, allowing users to see multiple layers of their screen at once. Liquid Glass also creates more movement on your interface by morphing into your display. For example, as messages pop up on your home screen, the time display starts to shrink to accommodate them. The color of Liquid Glass also shifts depending on the content on your screen and adapts between light and dark environments. "From navigating apps to system experiences like the lock screen notifications and control center app icons have been crafted with multiple layers of Liquid Glass and come to life in light mode, dark mode, colorful, new tints, or an all new clear look," said Dye during the company's keynote Monday. Apple Intelligence Apple also delivered long-awaited updates to Apple Intelligence, the company's artificial intelligence system that's now integrated with ChatGPT. AI-powered features arriving this fall include Live Translation, which automatically translates messages as they're being received. "So if you're making plans with some new friends while studying abroad, your message can be translated as you type and delivered in their preferred language, and when they respond, each text can be instantly translated for you," said Leslie Ikemoto, an engineering director at Apple said at the conference Monday. Visual Intelligence, another AI tool, allows users to take a screenshot of an image they see online — say, a cute sweater they come across on one of their apps — and then look up where to find a similar design online. They can also ask ChatGPT specific questions about the image, such as, keeping with the example of the sweater, "What material is this made of?" Another feature builds on Apple broad selection of emojis by giving users the power to combine and personalize existing emojis to create their own unique expressions. In their presentation, Apple showed how someone could merge the lightbulb emoji with the sloth emoji to indicate they were the last one to get a joke, for example. Still lingering on Apple's to do list is new AI integrations for Siri. Apple introduced updates to the voice assistant at last year's conference, but the full suite of upgrades for the voice assistant have yet to take effect. "We're continuing our work to deliver the features that make Siri even more personal," said senior vice president of software engineering Craig Federighi on Monday. "This work needed more time to reach our high quality bar, and we look forward to sharing more about it in the coming year." In a research note, Wedbush tech analyst Dan Ives noted that the Apple Intelligence rollout has been slower than expected, but also estimates that over the next few years, 25% of the world population will access AI through an Apple-powered device. "While many on [Wall] Street are heading into WWDC as underwhelming given the slower-than-expected rollout of Apple Intelligence, we disagree with this bearish narrative and strongly believe this will be the start of AI monetization period of the Apple ecosystem as the company will continue to lay the foundation through its new operating system updates across Mac, iOS, iPad and others with its '26" update,'" Ives said. contributed to this report.
