s5 screen suddenly small

[Android Central Question]

So i was downloading an app and it required "root access" i wasnt sure about what it was but pressed ok nevertheless. Suddenly my phone restarted and everything in the screen was smaller, everything. The keyboard is the only thing that stayed the same size. I can change the font but everything is still small. I really dont know what happened or how to fix it and would really appreciate some help. Id upload some screenshots so you could see but apparently i cant do it

Welcome to Android Central! Is the phone rooted? What app were you installing, and where did you install it from? Can you uninstall that app?
