next button behavior changed by itself?

[Android Central Question]

until today hitting the next button on my S7 showed all open apps in cascading list of full sized screens layered on top of one another. But as of today it shows instead a group of small bars with the app name on them. I cannot figure out how this changed, I didn't receive any updates and have deliberately changed any settings. And I would really like it back the way it was if anyone knows how to fix this, thx.

I don't know why it happened or how to fix it, but to keep confusing people, refer to it as the Recents button. It's your recently-used apps, not the next one you should run.
