I want to know the answer to the following question:
How many mobile phone manufacturers signed the EU's common EPS (MoU)?
All the background I'm provided with is that "The European Standardisation Bodies CEN, CENELEC and ETSI (independent of the OMTP/GSMA proposal) defined a common External Power Supply (EPS) for use with smartphones sold in the EU based on micro-USB.". Is that enough to answer the question?
