What app is this, and what do I need to uninstall to get rid of it

[Android Central Question]

Whenever my phone rings, or I make a phone call, I am getting a really annoying interface. I have no idea what app I need to kill in order to remove it. Anyone have any ideas?

I can't post a screenshot directly. Basically the link is imgur.com/gallery/lA6wk

You have any Microsoft apps installed? Go through all your recent app installs and remove them one at a time until it stops.
