Welcome to Android Central! I assume you mean that the screen goes to sleep while you're playing a video, and then when you try to turn it on, you see the lockscreen first, correct? You don't mean that the screen is freezing, right?

Are you watching the video using an app like YouTube, or are you streaming it on the mobile browser?
