Going to take advantage of an Android thread here to ask something that has driven me crazy for ~3 years:
How do I disable "pop-down" notifications? i.e. facebook messenger, on receiving a message, drops down a little message box from the top with that message. It stays there for about 2 seconds and then disappears... unless further messages in that chat appears.
The only way I can disable this is by muting that chat, which is not ideal. Same for Hangouts and other messaging apps. It drives me insane.
Swipe a notification to the side a little bit, and you get a gear icon. Tap that, and you can set that app's max allowed notification importance. You can block all notifications, relegate them to only being visible when you pull down the notification bar, or allow normal icons but not "peeking" notifications.
Yep, there's a new feature in Android O that gives you full control over notifications. You can have them make a sound and pop up, only make a sound, make no sound, or not show up at all. And you can set that per app, and even per notification type if they are targetting O api
Not the OP, but my experience is some apps(integrated?) use "android system" for notifications despite the app's notifications being disabled. May be a 'root' issue, but root also makes fixes via terminal or adb viable.
I believe the feature you're talking about is "Heads Up Notifications" introduced in Lollipop (5.0). Go into Settings > Notifications, find and turn off Heads up. Then you'll just see the icon in the top bar, but no drop down.
