Exploring the Hidden Features of Your Smartphone

31 December 2025

Smartphones have become an essential part of our daily lives. From staying connected to managing tasks and entertainment, these pocket-sized powerhouses do it all. But did you know that your smartphone has hidden features that can make your experience even better?

Many of these features are buried deep in settings or require a specific combination of actions to activate. In this article, we'll uncover some of these hidden gems that can help boost your productivity, security, and overall smartphone experience.

1. Secret Codes for Quick Access

Most smartphones come with secret USSD codes that give you access to hidden menus and diagnostic tools. These codes vary by manufacturer and operating system, but here are some useful ones:

- Check Your IMEI Number: Dial `*#06#` to instantly display your phone’s IMEI number.
- Test Your Phone’s Hardware: On Android, typing `#0#` opens a diagnostic menu to check your display, sensors, and more.
- Field Test Mode (iPhone): Dial `3001#12345#` and press call to access a menu that provides in-depth network and signal strength details.

These codes can help you troubleshoot issues without needing third-party apps.

2. One-Handed Mode for Better Accessibility

Struggling to use your phone with one hand? Many smartphones now have a built-in one-handed mode that shrinks the screen for easier navigation.

- On iPhone: Lightly swipe down on the bottom edge of the screen to bring content closer.
- On Android: Enable one-handed mode in Settings > Advanced Features (varies by brand).

This feature is a game-changer when you’re juggling multiple tasks or holding your phone with one hand.

3. Hidden Trackpad in Your Keyboard

Ever tried editing text on your phone and found it frustrating to move the cursor? Your keyboard has a hidden trackpad mode!

How to activate it:

- iPhone: Press and hold the space bar, and the keyboard transforms into a trackpad, letting you move the cursor freely.
- Android (Gboard): Press and hold the space bar to use the trackpad or swipe along the space bar for precision cursor movement.

This small trick can save you time when correcting typos or positioning the cursor in a long message.

4. Hidden Apps with Guest Mode

Ever handed your phone to someone and worried about your private photos or messages? Guest Mode is your best friend!

How to activate it:

- Android: Go to Settings > System > Multiple Users > Enable Guest Mode.
- iPhone: While iOS doesn’t have Guest Mode, you can enable "Guided Access" (Settings > Accessibility) to lock the phone to a single app before handing it over.

This feature is perfect for lending your phone without compromising privacy.

5. Screen Pinning: Lock an App on Screen

If you want to keep someone restricted to just one app (like a kid watching YouTube), Screen Pinning is a must-use feature.

How to enable it:

- Android: Go to Settings > Security > Screen Pinning and turn it on. Once enabled, open the app, press the Overview button (Recent Apps), and pin the app.
- iPhone Alternative: Use Guided Access to limit access to a specific app.

Once pinned, the user can't exit the app without entering your phone’s authentication method. Great for preventing accidental snooping!

6. Built-in Document Scanner

Did you know your smartphone has a built-in document scanner? Forget downloading extra apps!

How to use it:

- iPhone: Open the Notes app, tap the Camera icon, and select "Scan Documents."
- Android: Open Google Drive, tap the "+" button, select "Scan," and capture your document.

This feature is incredibly useful for scanning receipts, documents, and important papers on the go.

7. Back Tap Gesture for Quick Actions

Imagine tapping the back of your phone to take a screenshot or open an app. Well, it's possible!

How to enable it:

- iPhone: Go to Settings > Accessibility > Touch > Back Tap and set a double or triple tap shortcut.
- Android: Some Android phones (like Pixel devices) offer a similar feature under Settings > Gestures. Others may require third-party apps for this function.

This feature adds convenience and makes common tasks quicker.

8. Wi-Fi Sharing with QR Code

Instead of telling guests your complicated Wi-Fi password, why not share it instantly with a QR code?

How to generate a Wi-Fi QR Code:

- Android: Go to Wi-Fi settings, tap on the connected network, and select "Share." A QR code appears for instant access.
- iPhone Alternative: While iPhones don’t generate QR codes, you can automatically share Wi-Fi with nearby Apple devices by bringing them close and selecting "Share Password."

This trick makes sharing Wi-Fi faster and more secure.

9. Customize Vibration Patterns for Contacts

Want to know who's calling without looking at your screen? Custom vibration patterns can help!

How to set it up:

- iPhone: Go to Contacts > Select a Contact > Edit > Ringtone > Vibration > Create New Vibration.
- Android: Some Android devices allow this under Contact settings, or you can use third-party apps to achieve the same effect.

Now, you’ll recognize important calls just by feeling the vibration. No need to check your phone constantly!

10. Dark Mode Scheduling for Eye Comfort

Dark Mode is great for reducing eye strain, but did you know you can schedule it automatically?

How to enable scheduling:

- iPhone: Go to Settings > Display & Brightness > Toggle “Automatic” and set a custom schedule.
- Android: Settings > Display > Dark Mode > Schedule (options may vary by device).

Using Dark Mode at night can help reduce blue light exposure and even save battery on OLED screens.

11. Emergency SOS Shortcut

Your smartphone can quickly call for help in emergencies with built-in SOS features.

How to activate Emergency SOS:

- iPhone: Press the side button and volume button together, or rapidly press the power button five times.
- Android: Go to Settings > Safety & Emergency > Emergency SOS and customize actions like auto-calling emergency contacts.

This life-saving feature ensures you’re prepared for unexpected situations.

12. Live Captions for Any Video

Struggling to watch a video without sound? Live Captions can generate real-time subtitles for any media.

How to enable Live Captions:

- Android: Settings > Accessibility > Live Caption.
- iPhone: Enable Live Captions in Settings > Accessibility > Live Captions (Beta).

This feature is fantastic for accessibility and watching videos in noisy environments.
