If your phone does not have enough RAM available, Scope tends to crash when loading panos. As of version 1.03, the Scope App uses mipmaps to make panos look sharper and overall better but requires even more RAM as a result.
Memory usage is directly related to the resolution of your panorama. So if your 18432 x 1536 panorama is crashing the application, outputting it as a lower resolution should help.
