How can i get my Phone to blackout with a wallet phone case?

[AC Question]

I bought a boost mobile cell phone ( Galaxy prevail lte ) and Got a wallet phone case for it. What i want to know is when i open my phone that has the wallet case on, will the screen come on. just like when I'm on a phone call and i hold the phone to my ear the screen black out. can i do the same thing with the wallet case?

It might, but I doubt it. Most cases like the flip cases, the phone sensors are designed with that function in mind. This might be a similar situation.
