Since the upgrade to marshmallow a few days ago, I only get the little envelope notification and my command keys lighting up when I have a new text message. Before, I would see it scrolling through the top of the notification bar if I had another app open (example fb) so I didnt have to leave the app to read it. Now I do I have the preview message turned on under messages and notifications. I have restarted it, pulled the battery, memory card and sim card but still nothing. My husband and friends dont have this problem? Anyone know how to fix it?
