Show Notifications missing in app settings I'm trying to disable app notification for a particular app. The usual method is to go to System > Apps > click on the app > uncheck the "show notifications" checkbox.

The problem is, this checkbox doesn't appear for this app, or for any of the random apps that I sampled which are installed on my phone (eg. GMail).

Am I missing something? I'm running a Samsung Galaxy (SGH-S730M) with Android 4.0.4. I found instructions (with screenshots) that look like they date back to Android OS 2.x or 1.6.
The feature isn't present in Android 4.0.4: it was added in 4.1.
