Not sure if this had been mentioned before, but it's something that I use all the time, so I wanted to share.
For those of you that take advantage of the S-pen and action memo, if you use it to write down grocery/shopping lists, when you open up the list in action memo, you can actually put your phone in standby and when you wake the phone, the list will still be open on top of the lock screen. No need to unlock the phone, in order to see the list again. For me, this is a huge help when I'm shopping because I'll go to one isle, get all the items on the list, take the phone off standby, cross off the items on the list, and then put the phone back on standby. I do this continually throughout the store, until I've obtained all the items I need.
Love the G-Note series!
