Screen stays black

I operate a Samsung SGH 1497 with Android 4.1.2

11.93GB with 3.63 GB remaining.

I launch App but screen stays black. The ribbon shows, and has some versatility.

Even the stock “Dance Center” tries to load than then goes black.

took a video should you wish to review.

Hey I am facing the same issue can someone help us. Thanks in advance!

never resolved this. recently, I wipe a bunch of memory and other apps began to operate better.
have not tried SU since then- you might ensure there is a much memory available as possible and give it a shot- let me know …GLUCK!
