I recently changed my default messaging application from the standard Note 4 Messages to Verizon's Message+, so I can send and receive MMS via Wi-Fi. However, since making the change both the LED and Smart Alert (vibration when the device is picked up to notify of missed messages) have ceased to notify me of missed text messages even after the two reminders I have selected in the Message+ Settings menu have sounded. I have tried selecting each of the available LED color choices in the Message+ Settings menu thinking that perhaps I had chosen a color the Note 4 LED is not configured to reproduce to no avail. Suggestions?
