How do I unlock a frozen screen?

[AC Question]

I was in the middle of texting, and everything froze. None of the buttons will change anything. There is a series of pressing the power button and the home button a few times and holding one or both of them, but I can't remember what it is.

Hi, welcome to the forums! What phone and Android version do you have? Which texting app were you using?
