/sys/class/graphics/fb0/bits_per_pixel You'll be disappointed to know that it ships stock with 16-bit color (65,535) output. We are display limited, but allowing the display to have a wider color gamut can only help when looking at pictures or even playing games. There's quite a bit of color dithering at 16-bit and it's worsened with the poor Pentile screen Motorola chose. Anyway: open the file with rw root permissions, change 16 to 32, and save. The screen will flicker briefly and it'll now display 32-bit (24-bit color + 8 bit alpha). Don't expect banding to go away with grayscale things like Android's widgets. This is primarily for color banding seen in pictures or other complex color things.
