Why does my phone glitch?

[AC Question]

why does my phone glitch?

Every time I am on my phone and either texting or doing something else my phone will glitch and the screen will turn completely black for about 2 seconds. It looks like it is going to either close out of what I am doing or shut off. Does anybody know why this is happening?

We need to know what phone you're talking about and whether it's still under warranty - because if it is, just have it replaced.
