Motorola shares fell 4 cents to US$7.64 in pre-market trading.

The Schaumburg, Illinois, company reported net income of US$162 million, or 7 cents per share in the April-June quarter. That's up from US$26 million, or 1 cent per share, a year ago.

Excluding items, Motorola would have earned 9 cents per share. That exceeded the average estimate of analysts polled by Thomson Reuters by a penny a share.

Overall revenue fell 1.5 percent to US$5.4 billion from US$5.5 billion. Analysts expected US$5.2 billion.

Revenue in the cell phone unit was US$1.7 billion, up from US$1.6 billion in the first quarter. The total number of cell phones still fell, from 8.5 million to 8.3 million, but Motorola sold more of its pricey smart phones: 2.7 million, compared to 2.3 million in the first quarter.
