Why does my phone keep going black?

[AC Question]

I have an Alcatel one touch fierce and I've had my phone for about 2 months now and its been working great. Besides the fact that the screen goes black every 5 seconds after being left alone, but it doesn't lock. It's been hard reading long messages when I have to touch the screen whenever it starts to go dark. I tried to fix it by changing the lock settings but that does not work either. Please help.

Welcome to AC.

Try Settings, Display, Screen Timeout.
