Useful Functions of Samsung Devices: Unlocking Hidden Power

In today’s mobile- and smart-device-driven world, owning a device from Samsung means you’re not just getting hardware — you’re tapping into an ecosystem full of smart features waiting to be discovered. Whether you’re using a Galaxy phone, a tablet, or a smart appliance, there are many useful functions built into Samsung devices that often go unnoticed. In this post, we’ll walk through several of these features, show you how to enable them, and explain why they might make your life easier.

1. Multi-Control & Screen Mirroring

One of the most practical features found in recent Galaxy devices is the ability to connect and control multiple devices seamlessly. For example, the “Multi Control” feature lets you use a keyboard and mouse connected to one Samsung device to control another linked Samsung device — dragging and dropping files between them.

Similarly, “Smart View” allows you to mirror your phone’s screen to a TV or compatible display. This makes sharing videos, photos or presentations far more convenient. Samsung

Why it matters: If you work across devices (phone + tablet + TV) or like to project content for family or clients, being able to control everything from one interface saves time and hassle.

How to enable:

For Multi Control: Go to Settings → Connected devices, enable Multi Control on all devices. Drag & drop between devices once connected. Samsung
For Smart View: On your phone, pull down the Quick Settings panel, tap “Smart View”, select the display you want, and mirror away. Make sure both devices are on the same WiFi. Samsung

2. Digital Wallet & Secure Sharing

Security and convenience go hand in hand with Samsung’s built-in features. With the Samsung Wallet app (or Digital Wallet), you can securely store payment cards, IDs, tickets, boarding passes and more — all behind Samsung’s Knox Vault security system. Samsung

Another useful tool is Private Share—designed for securely sharing sensitive files between compatible Samsung devices. Samsung

Why it matters: Minimises the need for physical cards or print-outs, and it offers strong security for personal data sharing.

Tips:

Enable biometrics (fingerprint or face) for Samsung Wallet for extra protection.
Before sharing files, ensure the receiving device is trusted and connected.
Regularly review what’s stored in your Wallet and remove items you no longer need.

3. Digital Wellbeing & Usage Control

In our always-connected lives, staying in control of how we use our devices is crucial. Samsung’s Digital Wellbeing tools help you monitor your screen time, set app usage limits and manage content access — especially useful for parents. Samsung

Why it matters: Enables healthier device habits, better focus and more mindful usage. Also helpful for managing children’s device time.

How to use:

Go to Settings → Digital Wellbeing & parental controls.
Review the Dashboard for app usage.
Set limits, bedtime mode or schedule focus times.
Consider enabling content restrictions if children use the device.

4. Hidden & Advanced Features You Should Enable

Samsung devices hide a number of advanced or lesser-known features that deliver big gains in convenience. According to a comprehensive guide by Tom’s Guide, features include: taking selfies with gestures, customizing side-key shortcuts, enabling RAW photos, locking home screen layouts, running dual apps and more.

Another list from Android Police highlights such functions as Secure Folder, Edge Panels, dual-messenger/clone apps and deeper customization. Android Police

Why it matters: These hidden features let you tailor your Samsung device to your way of working or living — instead of working around the defaults.

Some suggestions:

Enable “Double-tap display to turn on/off” for quick wake. Tom’s Guide
Create a “Secure Folder” for private apps and files. Android Police
Use Edge Panels (if your device supports them) to get fast access to tools and contacts. Android Police
Try running two copies of the same app (for example two WhatsApp accounts) if dual-SIM is active. Tom’s Guide

5. Samsung AI Features (for Newer Devices)

If you have one of the newer Samsung devices (for example S24, S25 series or newer tab/flip devices), you’ll find powerful AI-driven functions embedded in the OS. These include “Circle to Search”, “Writing Assist/Chat Assist”, “Audio Eraser” for videos, “Note Assist” inside Samsung Notes, and more. Samsung

Key examples:

Circle to Search: Use your finger or S Pen to circle an object or text in any app or image to search for related information online. Samsung
Audio Eraser: When editing a video in the Gallery app, you can remove unwanted background noises like wind or voices. Samsung
Note Assist: In Samsung Notes, you can summarise, translate or format your notes automatically with AI. Samsung

Why it matters: These features turn your device into more than just a phone — they become intelligent assistants that help you write, search, edit and multitask faster.

Usage tips:

Check if your device model supports these AI features (some are limited to later models or certain One UI versions). Samsung
Explore these features right after a software update — often new AI tools are added.
Use “Circle to Search” when you’re unsure what something is (e.g., an object in a photo or a menu in a foreign language) — it can save you a lot of time.

6. Customize & Automate with Routines

Another smart function in Samsung devices is the ability to create routines and automation based on conditions — for example time of day, location, connection to WiFi, headphone connection etc. While older versions called this feature “Bixby Routines”, newer One UI versions may just call it “Modes & Routines”. Using these you can automate tasks like switching sound profiles, launching apps, turning on Do Not Disturb, adjusting brightness, etc. Samsung+1

Why it matters: Automation removes repetitive steps and makes your device adapt to your lifestyle — not the other way around.

Example routine idea:

At 22:00, when you connect your phone to your bedside charger: turn on Do Not Disturb, reduce screen brightness, launch a sleep tracking app.
When you plug in your headphones: open your favourite podcast app & set volume to a comfortable level.
When you arrive home: connect to home WiFi, turn off mobile data, disable roaming, open your smart-home control app.

7. Productivity & Multitasking Enhancements

Samsung has made strong gains when it comes to productivity features — especially for those who use their phones/tablets as work tools. For example, the “7 powerful Galaxy S25 features for productivity” article highlights how the personal assistant via Galaxy AI can manage cross-app workflows, transcription, schedule awareness, and seamless connection with other Samsung devices (tablets, watches) in the ecosystem. Samsung Business Insights

Why it matters: If you use your device for more than calls and social media — say emails, documents, video calls, multitasking — these features can boost your efficiency significantly.

Suggestions:

Use split-screen or app-pairing to keep two apps visible at once (e.g., a document and a reference webpage).
Use drag-and-drop between apps or devices (available with Multi Control).
Explore the productivity assistant and workflow features on newer devices — check your Settings for “Galaxy AI” or “Personal assistant” options.

8. Security, Privacy & Device Health

Finally, no list of useful functions would be complete without security, privacy and device maintenance. Samsung devices include helpful tools to keep your device healthy and your data secure. Some features include: device optimisation, storage cleanup, battery usage monitoring, and secure folders for private data. The Sun

Why it matters: Devices slow down over time, storage fills up, and unused apps drain battery — proactive maintenance keeps your phone running smoothly. And privacy features mean your personal data stays safe.

How to use:

In Settings → Device Care (or Battery & device care) run an optimisation check. Close power-hungry apps, clear cache/storage, check battery health. The Sun
Use Secure Folder to isolate apps and files that you don’t want exposed.
In the Wallet or Wallet-equivalent app, ensure biometric lock is enabled.
Review permissions for apps (camera, mic, location) and disable those you don’t use.
