Advanced: com.samsung.android.da.daagent Advanced Vendor documentation
Samsung's Dual Messenger, which installs a second copy of a messaging app so you can use two accounts. You can disable it, with a caveat: read what stops working first.
What it does
Dual Messenger lets you run a second copy of supported messaging apps, such as WhatsApp or Facebook Messenger, with a different account and its own contact list. You turn it on per app under Advanced features in Settings, and the second copy carries a badge on its icon. It runs while second copies exist.
If you disable it
Second copies of messaging apps stop working. If you use a second account through Dual Messenger, back up those chats first, because removing the second copy deletes its data.
How to disable it
On most phones Settings greys out Disable for this package, so ADB is the way to turn it off. The commands below work without root and can be undone.
