Want to Open an iPhone App Without Touching the Screen? Here’s How

You can launch any app and perform other useful functions just by tapping the back of your iPhone.

If you don’t have an iPhone 16, you might think you’re missing out on the new Camera Control button that lets you quickly open the camera app. Luckily, if you have an iPhone from the past few years, there’s already a hidden «button» that can open the camera — or any other app. To access it, all you need to do is tap the back of your device.

The feature is part of the Back Tap tool in your iPhone’s accessibility settings. Once enabled, it can trigger almost anything your phone can do, from turning on the flashlight to opening Shazam before a song ends. You can even set it to open the Control Center, take a screenshot or run a custom Shortcut with two or three quick taps. It’s fast, discreet and surprisingly powerful once you set it up.

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. 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 limited to just 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

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.

The FDA Just Upgraded an Egg Recall to the Highest Severity Level. Are You Affected?

Over 6 million eggs were caught up in a salmonella-related recall in September. Now, the FDA says there’s a «reasonable probability» of serious illness.

Scan your shelves for cartons from Black Sheep Egg Company. The company voluntarily recalled more than 6 million eggs after the US Food and Drug Administration found environmental samples at one of its processing centers tested positive for salmonella.

«Of the samples collected, 40 environmental samples were positive for salmonella including seven different strains of salmonella,» said the initial recall alert from the FDA. «Some of these strains are known to cause human illness.»

While multiple Black Sheep Egg Company products have been affected by this recall, the FDA identified 12- and 18-count cartons of Black Sheep Egg Company Free Range Large Grade A Brown Eggs as Class 1.

This is the agency’s highest-severity level recall, and it warns against consuming a product that could «cause serious adverse health consequences or death.»

Which products are affected by the recall?

The recall doesn’t affect every Black Sheep Egg Company egg carton, but check the eggs in your fridge.

You should get rid of the following products if they have a Best By date between Aug. 7 and Oct. 31, or a UPC code that reads 860010568507 or 860010568538:

Free Range Grade A Large Brown Eggs, 12-count cartons
Free Range Grade A Large Brown Eggs, 18-count cartons
Free Range Grade AA Large Brown Eggs, loose-packed in boxes
Free Range Grade AA Medium Brown Eggs, loose-packed in boxes
Free Range Grade AA Large Brown Eggs, loose open skid
Free Range Grade AA Medium Brown Eggs, loose open skid
Free Range Grade AA Large White Eggs, loose open skid
Free Range Grade AA Medium White Eggs, loose open skid
Free Range Grade AA Large White Eggs, 12-count cartons
Free Range Grade AA Medium White Eggs, 18-count cartons

Additionally, Black Sheep Egg Company is a supplier for Kenz Henz in Texas. Kenz Henz is also issuing a voluntary recall of the following product if it has a Best By date between Oct. 11 and Oct. 17 and a UPC code of 86949400030:

Grade AA Large Pasture Raised eggs, 12-count cartons

Where did the affected eggs come from?

According to the FDA, the salmonella samples were found in Black Sheep Egg Company’s Arkansas processing center.

While Black Sheep Egg Company cooperated with the FDA and voluntarily recalled the potentially contaminated eggs, it had already shipped products to other companies within Arkansas and Missouri. These eggs may have been repackaged and further distributed to other states, so this recall could expand over time.

What should I do if I find the affected eggs in my fridge?

If you find a recalled Black Sheep Egg Company or Kenz Henz product in your refrigerator, discard it immediately. If you’ve eaten any eggs, monitor yourself for signs of illness.

«Illness usually occurs within 12 to 72 hours after eating food that is contaminated with salmonella, and the symptoms usually last four to seven days,» the FDA statement said. «Symptoms include diarrhea, fever, and abdominal cramps. Children younger than five, the elderly, and people with weakened immune systems are more likely to have severe infections.»

If you believe you’ve developed symptoms of a salmonella infection, contact a healthcare provider immediately.

If you find affected eggs in your home, carefully sanitize any countertops, surfaces or containers the eggs have touched. Wash utensils and cooking implements with hot soapy water, then wash your hands afterward.

Samsung TVs Now Can Provide Weather Forecast, Find a Pizza Place

The company is adding a Perplexity AI app to all of its new TVs and even older ones.

You’re sprawled on the couch, watching the latest stream of your favorite show. Why not plan your next vacation while you’re at it? That’s the thought behind Samsung’s latest AI innovation, the Perplexity TV app. It’s a standalone AI agent available on all 2025 Samsung TVs and, later this year, on 2023 and 2024 TVs with the latest OS upgrade.

Earlier this month, at the Berlin consumer-electronics show IFA 2025, the company introduced Samsung Vision AI, which allowed TV viewers to access more information about the shows and actors they were watching. Viewers can also use the Vision AI Companion in other ways, such as receiving recommendations for shows and movies. The Perplexity TV app builds on Vision AI’s skillset.

Don’t miss any of our unbiased tech content and lab-based reviews. Add CNET as a preferred Google source.

Samsung integrated AI across a wide range of its products, including smartphones, appliances, earbuds, tablets and TVs, as part of the company’s vision to «leap forward as an AI-driven company that makes the best use of AI, works with AI, and grows with AI,» executive Roh Tae-Moon said at the 2025 Tech Forum in Silicon Valley last week.

‘Curiosity can strike at any time’

Samsung partnered with Perplexity, a self-proclaimed «free AI-powered answer engine.» Samsung says its Perplexity TV app can provide the weather forecast, find you the closest pizza shop or tell you the date of the Kentucky Derby.

Ryan Foutty, Perplexity’s vice president of business, said creating an AI app for TVs makes sense because «curiosity can strike at any time» and that consumers should be able to access information from AI regardless of the AI-driven interfaces they are using.

Use the apps tab on your Samsung TV to access the Perplexity TV App, or hit the AI button on your remote to access Samsung’s Vision AI Companion. You can also ask the AI questions by speaking into the built-in microphone on the remote and TV, or using the on-screen keyboard.

CNET expert isn’t yet sold

CNET’s David Katzmaier saw Samsung’s AI-enhanced TVs earlier this year at CES 2025, and isn’t quite convinced that this is a vital addition.

«At first blush, a built-in AI agent doesn’t seem to me like a good reason to choose one TV over another,» Katzmaier said. «To make it worthwhile, Samsung needs to prove that it’s better than, say, Perplexity on your phone.»
