Galaxy S4 battery full notification sound
So I just got the new S4 yesterday and I noticed it doesnt play the notification sound when the battery is fully charged? It just vibrates and displays the LCD screen and I cant for the life of me figure out how to enable this?? If the feature has been taken off the new device then that really is annoying as id like to be notified by sound when my batter is fully charged like it did on my Galaxy Apollo and S2, Is this normal and how do I enable this?? Thanks.
