Motorola wont be assembling phones in the United States for much longer. The Wall Street Journal is reporting that the company will close its Texas factory — essential to its Moto Maker assembly process — by the end of this year. Motorola has since confirmed the unfortunate news to The Verge. And the reason is simple: Motorolas smartphones arent selling well enough to keep the place running. What we found was that the North American market was exceptionally tough, Motorola President Rick Osterloh told the Journal. The plants fate was thrown into question after Lenovo announced plans to purchase Motorola Mobility from Google early this year.
