Your smartphone is probably one of the most frequently used devices you own, but chances are you are only using a fraction of what it can actually do. Modern phones are packed with shortcuts, accessibility tools, multitasking features, privacy options, and clever controls that can make everyday tasks considerably easier.
Some of these features are obvious once you know where to look, while others are tucked away inside settings menus that most people rarely explore. Depending on whether you use an iPhone, Android phone, or Samsung Galaxy device, the exact options and menu names can vary, but the idea is the same: your phone may be capable of much more than simply making calls, sending messages, browsing the internet, and taking photographs.
Here are 10 useful phone functions that are easy to overlook and worth exploring.
1. Tap the Back of Your iPhone to Trigger Shortcuts
If you have a compatible iPhone, you may be able to control certain actions simply by tapping the back of the device.
Apple’s Back Tap feature allows you to assign an action to either a double tap or triple tap on the back of the phone. Once configured, you can use it to perform tasks such as taking a screenshot, opening a selected feature, activating an accessibility function, or launching a shortcut.
To explore it, go to:
Settings → Accessibility → Touch → Back Tap
You can then choose whether you want a double-tap or triple-tap gesture and select an available action.
This can be particularly convenient when you regularly perform the same task. Instead of navigating through several menus, a quick tap can become your shortcut.
Just remember that the available options can vary depending on your iPhone model and iOS version.
2. Use Split Screen on Android
Android phones can be surprisingly good at multitasking. One particularly useful feature is split-screen mode, which allows two compatible applications to appear on the screen simultaneously.
Imagine you are following a recipe while watching a cooking video, comparing information between two apps, or writing notes while reading a webpage. Rather than repeatedly switching between applications, you can display both at once.
The exact process varies between Android manufacturers and software versions, but it generally involves opening the recent-apps screen, selecting the app’s menu, and choosing an option such as Split screen.
Not every application supports split-screen mode, but many common apps do.
Once you get used to it, this feature can save an impressive amount of time, especially if you frequently multitask on your phone.
3. Create a Private Space With Samsung Secure Folder
Samsung Galaxy phones offer a feature called Secure Folder, designed to provide an additional protected area for selected apps and files.
Instead of keeping everything in the same general storage space, you can place certain photos, documents, applications, and other content inside Secure Folder and protect access using authentication options such as a PIN, password, or biometric security.
It can be useful if you share your phone with family members, want to separate personal material from other content, or simply want another layer of protection for sensitive files.
Think of it as a separate private area within your phone rather than simply another ordinary folder.
Because Samsung’s software changes over time, the exact location and available options may differ between Galaxy models and One UI versions.
4. Scan Documents Without Installing Another App
Many people install a dedicated scanning application when they need to digitize a document, but iPhone users already have document-scanning capabilities built into Apple’s apps.
In the Notes app, you can create a note and use the camera options to find Scan Documents. The phone can detect the edges of a page, capture the document, and save the resulting scan inside the note.
This is particularly useful for receipts, forms, handwritten pages, invoices, school documents, or anything else you want to keep digitally.
The advantage is convenience. Instead of searching an app store, downloading another application, creating an account, and giving that app additional permissions, you can use a feature already integrated into the phone.
Some other phone platforms also provide built-in scanning tools, so it is worth checking your camera, notes, or document applications before downloading a third-party scanner.
5. Turn Your Phone Into a More Accessible Device
Accessibility settings are sometimes overlooked because people assume they are only intended for users with specific disabilities. In reality, many accessibility tools can be useful to almost anyone.
For example, iPhones include Sound Recognition, which can notify you when the phone detects certain sounds. Depending on the supported options, these can include things such as alarms, doorbells, or other environmental sounds.
This can be useful when you are wearing headphones, working in a noisy environment, or simply want your phone to pay attention to sounds you might otherwise miss.
Other accessibility features can enlarge text, increase contrast, provide spoken descriptions, change touch behavior, or make navigation easier.
Spend a few minutes exploring the accessibility section of your phone. You may discover a feature that solves a problem you did not realize your phone could handle.
6. Pin One App Before Handing Over Your Android Phone
Have you ever handed your phone to someone so they could look at one photo, watch a video, or make a quick call, only to wonder whether they might accidentally open something else?
Android’s screen pinning feature can help in situations like this.
When enabled, screen pinning restricts the device to a selected application until you deliberately exit the pinned mode using the required unlock method.
This means you can give someone access to a particular app without giving them unrestricted access to everything on your phone.
The exact settings can differ depending on the Android manufacturer and version, so search your phone’s Settings app for screen pinning or app pinning if you want to activate it.
It is a small privacy feature, but it can be extremely useful when you frequently lend your phone to other people.
7. Make a Samsung Phone Easier to Use With One Hand
Large smartphone displays are excellent for watching videos, browsing websites, and viewing photographs, but they can sometimes be awkward to operate with one hand.
Samsung Galaxy devices offer One-Handed Mode, which reduces the usable display area so that controls are easier to reach.
This can be helpful when you are walking, carrying a bag, holding something in your other hand, or simply trying to reach the opposite corner of a large screen.
Once activated, the interface can be reduced and repositioned toward one side of the display.
The exact gesture or activation method can depend on the Samsung model and software version, but you can usually locate the feature by searching the Settings menu for One-handed mode.
It is one of those features that may seem unnecessary until you actually need it.
8. Turn Your iPhone Keyboard Into a Trackpad
Editing text on a touchscreen can be frustrating. Trying to place the cursor between two letters with your finger often requires several attempts.
Fortunately, iPhone users have a handy keyboard trick.
When typing, pressing and holding the space bar can turn the keyboard area into a trackpad. You can then move your finger around to position the cursor more precisely within your text.
This becomes especially useful when editing long messages, emails, notes, or documents.
Instead of repeatedly tapping the exact location where you want the cursor to appear, you can slide it into position.
Once you discover this trick, it can become one of those tiny conveniences you use almost every day.
9. Customize Quick Settings and Shortcuts
Your phone’s quick-settings area is designed to give you rapid access to commonly used functions, but many people never customize it.
On many Android phones, you can rearrange the available quick settings so that the controls you use most frequently are easier to reach.
Depending on your device, these may include Wi-Fi, Bluetooth, screen recording, flashlight, mobile data, hotspot, airplane mode, location, or other tools.
Samsung Galaxy phones also offer customizable shortcut areas and features such as Edge panels, which can provide quick access to selected applications and tools.
The benefit is simple: rather than searching through Settings every time you need something, you can place frequently used controls where they are immediately accessible.
Take a look at the edit option in your notification or quick-settings panel. You may find several useful functions that are currently hidden from your main view.
10. Scan QR Codes Directly With Your Camera
QR codes are now everywhere: restaurant menus, event tickets, product packaging, payment systems, websites, and advertisements.
The good news is that most modern smartphones can recognize QR codes directly through the camera or a built-in scanning function. In many cases, you do not need to download a special QR-code application.
Simply open the camera and point it toward the code. If your phone supports automatic QR recognition, a notification or link should appear.
This is a perfect example of a feature that became so common that many people forget it is built into their phones.
Before installing another scanning app, check whether your camera already performs the task.
Why These Hidden Features Are Worth Exploring
The most useful smartphone features are not always the flashy ones advertised when a new phone is released.
Sometimes the features that make the biggest difference are tiny conveniences: being able to position a cursor precisely, scan a document without another application, protect a private folder, use two apps simultaneously, or trigger a shortcut without opening a menu.
These functions can save time because they eliminate unnecessary steps.
They can also improve privacy and accessibility. Features such as Secure Folder and screen pinning give you more control over what other people can access, while accessibility tools can make your phone easier to use in a variety of situations.
A Few Things to Remember
Because smartphones come from many different manufacturers, there is no universal set of instructions that works on every device.
An option available on one Samsung Galaxy model may not appear on another. Likewise, an iPhone feature can depend on the particular iOS version and device model.
If you cannot find one of these functions, do not assume your phone is missing it immediately. Try searching the Settings app for the feature’s name.
It is also a good idea to keep your operating system updated. Manufacturers frequently introduce new functions, improve existing ones, or move settings to different locations.
And when experimenting with unfamiliar settings, avoid changing security or privacy options unless you understand what they do.
Make Your Phone Work for You
Most people spend hours each week using their smartphones, yet many never explore beyond the handful of apps and functions they already know.
That means there is a good chance your phone has useful tools sitting quietly in its settings, waiting to be discovered.
Try exploring one feature at a time. Set up Back Tap if you use an iPhone. Experiment with split-screen multitasking if you have Android. Check whether your Samsung phone has Secure Folder or One-Handed Mode. Look through accessibility settings and customize your quick controls.
You do not need to learn every function at once. Even discovering two or three new shortcuts can make your everyday phone experience noticeably smoother.
Conclusion :
Smartphones have evolved into remarkably capable little computers, and their most useful abilities are not always obvious. Features such as back-tap shortcuts, document scanning, split-screen multitasking, private storage, screen pinning, one-handed operation, sound recognition, customizable shortcuts, and QR scanning can make everyday tasks faster and more convenient.
What makes these functions particularly interesting is that many of them do not require buying a new phone or installing another application. They may already be sitting inside the device you carry with you every day.
So the next time you find yourself thinking, “There must be an easier way to do this,” take a moment to explore your phone’s settings. You might discover that the solution has been there all along.
Smartphones are designed to be powerful, but the real benefit comes from knowing how to use that power. A few minutes of exploration today could save you countless small frustrations in the future.
