Then execute the PM Disable-User command [06:45] 7. Check the App Settings page to make sure it's marked as "disabled" [08:21] Commands: adb devices adb shell pm disable-user --user 0 com.samsung.android.da.daagent Samsung has a number of pre-installed applications that sit and run in the background (doing whatever it is Samsung wants them to do). For me, this is not something I enjoy, so when I see a random notification appear out of nowhere, I do my best to make sure it doesn't happen again. That's what happened the other day with my Samsung Galaxy Note 10 smartphone. All of a sudden I received a notification from the Dual Messenger app and was told that it noticed I had the WhatsApp application installed. The goal of this notification, for Samsung, is to remind their users of the service and to (hopefully) get them to begin using it. Again, I don't like some service running in the background of the phone checking to see for when I install a certain application. So I went into the App Settings page for the Dual Messager application and tried to uninstall it. There is no uninstall button at all, and even Samsung has grayed out the Disable button. I figure, the next best thing is to go in and turn off notification for the application entirely. Should be easy, right? Except Samsung has made it so that we cannot turn off notifications for this app. We can't even control the permissions the application is automatically granted. This is when I begin to get annoyed and try the usual pm uninstall command within the ADB shell to uninstall bloatware. I've done these videos before. Except this command didn't work either. When looking into why, the reasons I found were that the Dual Messanger application isn't even an application itself. It's what's known as an app stub, and cannot be uninstalled in this way. Nor can it be disabled from the system either. We can, however, execute a different ADB shell command to disable the Dual Messenger service entirely. This will stop the app/service from running in the background. And will result in us no longer receiving any unwarranted notifications. This tutorial will work on all modern Samsung smartphones running the OneUI firmware. These commands actually work across all Android smartphones and tablets which are running Android Lollipop and higher. However, I have personally tested this on the Samsung Galaxy S8, Galaxy S9, Galaxy S10, and Galaxy S20. As well as the Galaxy Note 9, Galaxy Note 10, and Galaxy Note 20.
