Ever felt stuck carrying two phones just because you run two WhatsApp or Telegram accounts? Yeah, same struggle. Good news: Samsung Galaxy S25 has a built-in feature called Dual Apps (Dual Messenger) that lets you clone supported apps and run two accounts on one device — clean, simple, and no sketchy hacks.
This guide walks you through exact steps, real-world tips, common issues, and privacy insights so you can enable dual apps on your Galaxy S25 like a pro.
No fluff. Just stuff that actually works.
What Is Dual Apps (Dual Messenger) on Samsung Galaxy S25?
Dual Apps, officially called Dual Messenger, is a native Samsung feature built into One UI. It allows you to install a second instance of supported messaging apps on the same phone.
Each app runs independently:
- Separate login
- Separate chat history
- Separate notifications
- Separate app data
Think of it as two apps, one phone, zero drama.
Apps commonly supported
Support may vary by region and One UI version, but usually includes:
- Telegram
- Facebook Messenger
- Signal (region-dependent)
Not every app supports cloning — especially banking or payment apps.
Step-by-Step: Enable Dual Apps on Samsung Galaxy S25
Let’s slow it down and do it right.
Step 1: Open Settings
- From your home screen or app drawer, open Settings.
- Scroll down and tap Advanced features.
- This is where Samsung hides all the power-user goodies.
Step 2: Go to Dual Messenger
- Inside Advanced features, tap Dual Messenger.
- Your Galaxy S25 will scan installed apps and show a list of apps that support cloning.
- If an app doesn’t appear here, Samsung doesn’t officially support duplicating it.
Step 3: Enable the App You Want to Clone
Toggle the app you want to duplicate.
Samsung will:
- Create a second app instance
- Add a small dual-app badge on the icon
- Install it automatically
Confirm when prompted.
Step 4: Sign In to the Second Account
- Open the cloned app.
- Log in using your second phone number or account.
- The original app stays logged in — no conflicts.
You now have two independent apps running side by side.
How to Manage Dual Apps Like a Pro
Once enabled, you can fine-tune how dual apps behave.
Change notifications
Each app has its own notification controls.
If the cloned app feels quiet:
- Go to Settings > Notifications
- Make sure alerts aren’t blocked or battery-restricted
Identify the cloned app easily
Samsung adds a dual-app badge to the cloned icon.
This helps avoid accidentally opening the wrong account.
Remove a dual app safely
To uninstall the cloned app:
- Go to Settings > Advanced features > Dual Messenger
- Toggle the app off
- Confirm removal
This deletes data from the cloned app only — the original app stays untouched.

Common causes:
- Outdated One UI version

Privacy & Security: What You Should Know (Important)
Dual Apps run as separate app instances, but they still live on the same device.
Based on qualitative research from leading universities studying Android privacy:
- Most privacy risks come from permissions, not cloning itself
- Cloned apps should be treated like completely separate apps
- Each app can access contacts, storage, camera — if you allow it
Best practices
- Review permissions for both apps
- Enable two-factor authentication
- Avoid cloning banking or payment apps
- Lock sensitive apps with Secure Folder if needed
Samsung’s native Dual Messenger is far safer than third-party cloning apps.
Alternatives to Dual Apps (When You Need More Control)
If Dual Messenger doesn’t fit your use case:
Work Profile (Android Enterprise)
Best for business users:
- Strong data separation
- Corporate-level security
- Separate app store environment
Downside: more complex setup.
Third-Party Parallel Apps
Not recommended unless absolutely necessary.
- Higher privacy risk
- Potential data leaks
- Inconsistent updates
Native Samsung features always win here.
Conclusion
If you want to run two accounts on one Samsung Galaxy S25, Dual Apps is the cleanest and safest solution.
- No third-party tools
- No sketchy permissions
- No performance hit
Just a native Samsung feature that works exactly as advertised.
Once you try it, you’ll wonder why you ever carried two phones.
