I read somewhere that the drawing apps allow you to export drawings with layers as .psd files. Has anyone done this? Can you also export for Illustrator?
The best DRAWING application across the board for phones & computers is Autodesk Sketchbook Designer. I have it on my Note 2 & it can easily be exported to photoshop, illustrator, zbrush, Maya, etc, etc. it's also very simple to learn, doesn't need a lot of memory and is bloody cheap...
Notice, I emphasized DRAWING & not painting. Painting is a completely different subject...
