BlackBerry has launched a low-cost touchscreen device, the Z3, as the embattled smartphone maker looks to revive sales in emerging markets, Reuters has reported. The handset is the first in a line of devices being made with FIH Mobile Ltd, a unit of the giant Taiwanese Foxconn Technology Group best known for assembling gadgets like iPhones and iPads for Apple Inc. The Z3 is the first phone to be launched by BlackBerry since the new CEO, John Chen, took the helm late last year. “If the market doesn’t receive this product well, then we definitely have some negative issues to deal with,” Chen said. BlackBerry said it doesn’t have an official sales target for the device, but Chen said he expects to sell millions of Z3 handsets around the world, without disclosing further details.
