BlackBerry started generating cash again under Chief Executive Officer John Chen's turnaround strategy but the company's revenue declined. BlackBerry on Friday said that the company's revenue fell to $793 million from $1.19 billion a year earlier. Cash flow was positive $43 million in the third quarter, while the company had negative cash flow of $36 million in the second quarter.

The Waterloo, Ontario-based company reported a net loss of $148 million, or 28 cents a share, in the quarter ended Nov. 29.

The company recognized revenue on about 2 million smartphones in the quarter, down from 2.1 in the second quarter. About 46 percent of its revenue came from hardware, with another 46 percent from services. Software and other revenue was 8 percent.

Blackberry said that it continues to target sustainable adjusted profitability some time in fiscal 2016.

BlackBerry launched its Classic smartphone on Wednesday, hoping to help win back market share and woo customers still using older versions of its physical keyboard devices.

The company has also completed its acquisition of Secusmart, a privately held firm that specializes in voice and data encryption.

The terms of the deal were not disclosed.

Secusmart's technology is being used to protect the devices of government officials in both Canada and Germany, including the BlackBerry device used by German Chancellor Angela Merkel.

BlackBerry is also working with Boeing on Boeing's Android smartphone.

"We're pleased to announce that Boeing is collaborating with BlackBerry to provide a secure mobile solution for Android devices utilizing our BES 12 platform," BlackBerry CEO John Chen said on a conference call held to discuss its quarterly results.

The Boeing Black phone being developed by the aerospace contractor can self-destruct if it is tampered with.
