I've taken some nice photos with my NS4G and wanted to crop one of them. I have PicSay Pro, but unfortunately, it will not work with images at their native resolution, so the output is a much smaller image. I tried Photoshop Express, same result. It seems that neither of these will allow you to edit a photo and export at its original resolution. So aside from importing the photo onto my PC and cropping in Photoshop there, do I have any other options on Android?
