Finding an Old Zombie Game removed from playstore

This was a game I played around 2018 or so.

It's a zombie game where your character tries to survive a zombie world with the help of a friend that communicates through a phone or radio. You mostly hide or run away from zombies, gather resources, and find a way to escape to the next area.

The end is a twist where the friend was an intelligent zombie all along.

Can't recall the title at all, but help is appreciated.
