Why is my phone giving me weird messages when started up?

Sometimes when I turn on my phone, it gives me a screen that says Factory Mode. I can't get out of this black and white screen. I tried shutting it down, pressing volume buttons, and pressing volume buttons and power button, but it doesn't do anything. Sometimes it randomly changes screens. Right now, it's showing me

I am able to navigate through the options by pressing the volume buttons, but other than that I cannot do anything else.

This is the second time that it has happened to me, and the only way it works is if I drain it out of power and let it shut down on its own. Is there any other way? Please help!
