I am trying to take pictures with a smartphone camera of scratches which may/may not exist on another powered off smart phone. Is there a way to do this without changing the angle of the camera?

Change the angle of the lighting? To make scratches visible, you want them to be able to cast shadows (or rather have a shadow cast onto them), so the lighting should be quite from the side. Don't use an on-camera light or flash, obviously.
