How do I get my phone to be unlocked on the three android screen?

[AC Question]

My phone has been shutting off by itself and then turning back on. One day it shut off and when I tried to turn it back on it got stuck on the loading screen. I also brought it to at&t and the guy said that it isn't supposed to say "locked" in pink on the top of the screen. It does currently and I wanted to see if I could unlock it maybe that would help?
