One of the big features I was looking forward to was the ability to pin a note to the always on display. More specifically a "todo list". I can't figure it out on my AT&T variant. I've seen videos and when they take a screen off memo all they do is hit the on button and it shows up right below the time on the AOD. Not mine though, it just shows up as a notification bubble under the time. If I double click it, it takes up the whole screen and does away with the time and date. What am I doing wrong?
