Samsung Galaxy S6 - would like screen to turn on with incoming text

A

AC Question

On my previous S4, my entire screen would turn on and open to an incoming text message. It would also turn back on every 5 minutes or so until I attended to it. I can not find a similar setting on my S6. I prefer to not have beeps/vibrations due to my workplace. The little LED light is not enough notification.

Thanks for any help.
