As stated above, the spots are a symptom of the manufacturing process. The story is that its due to the adhesive they use too bond the AMOLED display to the back of the motherboard. It may have to do with the solvent in the adhesive. It's there in virtually all RAZR and RAZR MAXX phones to one degree or another.
