Yesterday, I downloaded Layer Paint v.1.3 and it was successfully installed on my cellphone. I explored it and some features have problems. Can't import very large image to Layer Paint. What I did, I import an image to Sketchbook Express and do linearts. After that, I exported into PNG file. Then, I tried to that file and it was imported. Since Sketchbook Express can't produce a transparent background, what I did again, I switch the blend mode from Normal to Multiply on that image so I can color it properly. After color, shade. After shade, export then DONE!! :D
