Stock Android is freezing my phone more and more?

[Android Central Question]

When I first got my phone this app didn't show however over time when I hit show apps button so I can close YouTube for example it is a green box app stating stock Android and when I tap it or swipe it away my phone locks up it's annoying this issue has increased significantly I thought about uninstalling it but I'm not sure what can I do?

What phone do you have, what carrier version is it, and what version of Android is it running?
