S6 Screen Glitched/Broken?

Hey guys. My wife's s6 just did something really weird and I have no idea how to fix it. Her screen seems to be glitched or messed up. I don't know how to describe it. When ever I turn the phone on the screen turns on for 2 secs but all the words and images are all over the screen and then the scree shuts off but the applications are still usable. I tried doing a restart but didn't work and I then tried upgrading it but also didn't work. I tried to kinda mess with the brightness but still nothing. We just got this phone like 3 weeks ago and it was working fine up to 20 mins ago. She hasn't dropped it or done any water damage. Can anyone please help me to see what is going on with this phone.

I cant provide photos because i am new user. If anyone know how i can get around this without posting 10 times let me know so i can show you the screen of my wifes phone. I posted a similar help post on android central with pictures if you need to see the screen.
