Why do most of the videos I play show up green and pixelated?

[Android Central Question]

Videos on my Galaxy S6 have always shown up as green and pixelated. Very few Videos do not. Almost all youtube videos and even some Snapchat stories show up this way. Why? Here's a screenshot of a Snapchat video and how it looks.

Can anyone help?

You've had this happening since DAY 1????
Looks like a hardware issue! I would have returned that ASAP

Welcome to Android Central! Does this also happen in Safe Mode? https://support.t-mobile.com/docs/DOC-29226

I agree with @mhinc, you'll probably have to get it exchanged, or bring it into a repair shop (if it's not under warranty).
