Do both messenger app copies get notifications separately?

Yes. Each instance created through Turn On/Off an Available app sends its own notifications, so you can tell which account received a new message without opening either app.

Can I remove the second app instance later?

Yes, return to Tap on Settings ➔ Tap on Advanced features ➔ Tap on Dual Messenger and turn the toggle off for that app. This uninstalls the second copy and its data.

Does Dual Messenger require a dual-SIM phone?

No, the feature works on any supported Samsung device. It is most useful on dual-SIM phones, but a single-SIM device can still run two accounts of the same app for personal and work use.

Why does the second app instance take up storage separately?

Each instance installed via Tap on Install keeps its own app data and cache, independent from the original. This is what allows both accounts to stay logged in but also means storage use is counted twice.

Samsung: Set Up Dual Messenger for a Second WhatsApp Account

Switching between two WhatsApp or Facebook accounts on one phone usually means logging out and back in every time, which gets tedious fast on a dual-SIM device. Samsung's One UI includes a built-in function that installs a second, independent copy of supported messenger apps so both accounts stay logged in at once. Not every messenger app on your phone supports this, which is why the option sometimes seems to be missing.

Install Dual Messenger Apps auf Samsung

Dual Messenger is a One UI feature that creates a second, independent instance of a supported messenger app on the same Samsung device. Both copies run with separate accounts, separate notifications, and separate chat histories, so you no longer have to log out of one WhatsApp or Facebook account to use the other.

This is especially useful on dual-SIM Samsung phones, where each SIM slot can be tied to its own messenger account. Without Dual Messenger, only one account per app can stay active, forcing constant logins whenever you switch numbers or contexts.

To set it up, go to Tap on Settings ➔ Tap on Advanced features ➔ Tap on Dual Messenger. There you see a list of supported apps already installed on your phone. Turn On/Off an Available app to enable the second instance, then confirm with Tap on Install. The second app icon appears on your home screen shortly after, marked with a small badge so you can tell the two apart.

If an app you need is missing from the list, it likely does not support Dual Messenger or needs an update first. In that case, using a separate work profile or a second device remains the only reliable alternative.

Frequently asked questions

Only apps that support running two instances appear under Tap on Dual Messenger. If a messenger is missing, update it from the Play Store first, since older versions are sometimes filtered out.
