[Q] Galaxy S3 Front Cam Issue

Hi guys,

I'm not usually using my front camera, but today i realized it has a big green-pink pixelated stripe.
What do you think about that? It might be a hardware of software/firmware issue?
What should i do?
Thanks!

I attached some photos taken with the camera and the stripe doesn't appear when it's too dark or bright..
