i.e. can you see more than the latest notification, and can you see who has messaged if it is part of a group message? I loved my Vivoactive 3, but i ended up changing it for the fitbit due to the notification being so rubbish. I miss the accuracy of the Garmin sooo much i would be tempeted to go out and get the 4s ... if it could improve the Notification function i think i would order it right now...
