Blackberry is to stop designing Smart phones in-house after 14 years, the company has announced.Once a market leader, the company has struggled to keep pace with modern handsets produced by rivals such as Apple and Samsung, reports BBC.In May, the company’s chief executive, John Chen, said he would know by September whether the hardware business was likely to become profitable.Now, Blackberry says it will outsource hardware development to partners. But the company has not yet confirmed when any further Blackberry phones will be released.‘I always wanted to make sure that we keep having the iconic devices,’ Mr Chen told BNN. ‘I just need to find a way to be efficient and be able to make money. I think we found the model.’The company said it sold about 400,000 Smart phones in its second quarter - fewer than the previous three months.‘Blackberry can`t keep producing its own phones indefinitely just to serve a small subset of its clients addicted to its home-grown devices,’ said Ben Wood of the CCS Insight consultancy.‘Blackberry had made no secret of the fact that it might shut down its own phone-making business. Pushing it out to a third party is a sensible solution - but any manufacturer making Blackberry branded devices will ultimately face the same challenges.’
