Notification Sound Cutting Off

[kapnkool]

Asking for a friend. She is noticing on her J7 that the text notification sounds are getting cut off abruptly when a text comes in. She has NO long conversations, volumes are turned up, and she's tried several different sounds to troubleshoot. It can be quite random as well..where some texts will play the full sound, while others will not play it. Any advice? Thanks in advance.
