samsung galaxy s6 active message ticker?

[olive242]

I just switched from a galaxy s3 to a s6 active. When I receive a message and my phone is locked, the notification ticker does not show the preview of the message, only the little envelope. Unfortunately, I use the ticker to read/skim the message while I'm at work. I've noticed the ticker working sometimes when I'm actually using the phone but I NEED it when the phone is just sitting on my desk locked. Please help.
