According to figures out from comScore, for the quarter ended June 30, Motorola accounted for 11.7% of all smartphone activity in the U.S., putting it as the fourth most-used smartphone brand in the U.S. But with that number down 1.1% from a year ago, this points to how the company unit sales are actually in decline there as well. In Google's last quarterly earnings, the first to include Motorola, Google noted that Motorola posted a GAAP operating loss of $233 million ($192 million for the mobile segment and $41 million for the home segment), equivalent to -19% of Motorola revenues in the second quarter of 2012.
