Why doesn't the double tap wake up the screen?

My screen isn't frozen, I can still wake up the screen on my Alcatel Fierce 4 Android by pressing the power button on the right side of the phone, but I'm so used to just tapping the screen to wake it up. Why doesn't the "tapping" method work anymore?

Answer this question I have this problem too

Is this a good question?
