Need notification sounds for all messages, including follow-up With updated Lollipop on Samsung S4, the notification is sounded for the first message from a contact, but not any of the follow-up messages.  Annoying to constantly check for reply messages by unlocking the home screen with the phone in my hand all the time.  All settings are set to full sound and vibration.  Any suggestions?
I have the same problem since updating to lollipop.  You might try another app for messaging called Messages Plus which can be downloaded from the play store.  It will alert you after every response.  I'm not crazy about the format but at least it does alert you after each response.
