How to use Galaxy S9 dual messenger to run two accounts of messenger apps simultaneously on Galaxy S9 and S9+?

You can simultaneously use two (or even three) accounts for WhatsApp, Facebook, WeChat, Facebook Messenger, Telegrams and other messenger apps with Galaxy S9 dual messenger feature

Galaxy S9 dual messenger makes it possible to have two accounts of the supported messenger apps (e.g., WhatsApp, Facebook Messenger, WeChat, Telegram, Viber…) and Facebook accounts in Galaxy S9 and S9+.

You can use these two messenger accounts simultaneously on Galaxy S9 or S9+.

Galaxy S9 dual messenger works on all Galaxy S9 and S9+ phones. It does NOT require the dual-SIM version of Galaxy S9 or S9+.

Dual messenger was first introduced in Galaxy S8. You can use the identical dual messenger feature on Galaxy S8, S8+, S9, S9+, Note 8 and Note 9.

This guide shows you how to use Galaxy S9 dual messenger to enable two accounts of messenger apps on Galaxy S9 and S9+. It also shows you how to disable individual messenger apps on Galaxy S9 dual messenger.

Why may you need to have two accounts of WhatsApp and other messenger apps in Galaxy S9 and S9+?

Many Galaxy S9 or S9+ owners may have different social profiles when they are in office, and when they are at home.

You may never want to mess up your personal WhatsApp or Facebook account with the account for work.

Some owners may want to show themselves differently in social media to buddies and to parents or teachers or supervisors.

Many Android apps support multiple profiles. For example, you can add multiple Google accounts to Galaxy S9. In Google+, you can quickly switch to different profiles.

But some apps limit one account on one device.

WhatsApp has been notoriously enforcing this policy since day 1. Facebook also requires you to sign out if you want to switch the account on the same phone.

But with more and more Galaxy S9 and S9+ owners use two SIM cards on the phone, there is a genuine need for running two messenger accounts concurrently on the phone.

Anyway, two or more WhatsApp (and other messenger apps) accounts can make your life easier by separating different aspects of your daily life.

Samsung initially tried to solve the work-life separation issue with the secure folder, which is a Knox-based container (like a small virtual machine, but not full Knox), in Galaxy S7 and S7 edge.

Secure folder works well in creating two spaces in one phone. But most owners do not use this feature because it is not so convenient. You … Read the rest

Galaxy S9 status icons are more or less universal in all regions; while Galaxy S9 notification icons depend on individual apps, whose developers can use whatever they want.
