<Calls a bit more active now>Sony's (SNE +2.2%) flagship Xperia Z Android phone is off to a strong start: Digitimes reports initial volumes allocated for Japan, France, Germany, Hong Kong, and Taiwan fully sold out on the first day of pre-sale orders. The Verge just gave the Xperia Z a score of 7.2/10: it's likes the Z's sleek design, waterproofing, headphones, and battery life-boosting Stamina mode, but not its camera and ergonomics. Sony is hoping to sell 50M smartphones in FY13 (ends in March), up from 34M in FY12
