By Michael Gold TAIPEI (Reuters) – Taiwans HTC Corp will return to growth in the final three months of 2014 after a bruising few years that has seen market share dwindle amid steep sales declines. The October-to-December period will see the companys first rise in year-on-year total revenue in 12 quarters, company chief financial officer Chialin Chang said after the firms quarterly investor conference. Those products likely will include HTCs first-ever phone based on the Windows operating system from Microsoft Corp, a partnership Chang said was going well. HTC is also working on a smartwatch with Silicon Valley internet giant Google Inc, but Chang wouldnt say when the product would hit the market. Sales at the beleaguered phone company, which once sold one out of every 10 smartphones worldwide, have only notched two months of year-on-year growth out of the past 32.
