I dropped it at my school and was fine until I got home. I dropped it 5 times on a road and sidewalk. What happen this time?
@kayanna based on this " dropped it 5 times " it is most likely a broken LCD. Of course it is possible that it is a broken/dislodged display cable but unless you disassemble it, it will be hard to say. Let us know what exact model your Galaxy is and post some pictures of what your screen shows with your question. Use this guide Adding images to an existing question for that.
