Hi,

Just a week ago i purchased samsunggalaxy j2. Since last 3 days i noticed when the phone locked the home screen truned to black and white. But when i using phone..everything is okay. I face this problem only when phone got locked.

Is this any major problem or not?? And how can i solve this issue?

Sounds like an issue to me. Since it is brand new, I would take it back and have them replace it.
