My hopes are that someone knows how to disable these in UI 2.1. They just kill me when I am trying to type messages and a window keeps popping up over my work with incoming messages. Stupid and so GD iOS'ish it's ridiculous!! The answer before UI 2.1 was the simple command "adb shell settings put global heads_up_notifications_enabled 0" which Samsung must have changed the control variable. I am really hoping someone technical can tell us the new way to disable these annoying pop-ups again which we've been able to do so since Galaxy S5!
I've been asked by a lot of friends on how to disable those notifications which pop up on the top of your phone's screen. They are mistakenly called "pop-up notifications", but their real name is Heads-Up notifications and can be really useful, but sometimes they are extremely annoying. Specially if you need to use a button or something that is located on the top of the screen right when the notification appears. Some ROMs do allow to turn them off in the Settings, but most of them don't.
So in this thread (which is my first here on XDA) I'm gonna put all the info I gathered during my research about disabling the Heads-Up notifications. These methods will COMPLETELY disable them for all applications while MAINTAINING regular notifications in the status bar. All of these methods are free. Some require a rooted device and some don't.
1- ADB method (using your computer) [FREE]
Before trying this method, make sure you have installed Android ADB in your computer, that your phone is connected AND that you have "USB debugging" option enabled in the phone Settings.
If you don't have Android ADB, you can download it here: http://forum.xda-developers.com/show...php?p=48915118. If you have any questions concerning ADB and how to use it, take a look at this thread: http://forum.xda-developers.com/show....php?t=2225405
a) Open a terminal and check if the device is connected using the following command:
b) You should see your phone on the list that appears. Now use the following command:
