Taiwanese-based smartphone manufacturer HTC has been struggling recently, having just announced its 25 straight month of declining year-on-year sales.

In order to right the ship, current CFO Chialin Chang has been appointed as the new global head of sales. According to a statement posted by HTC, Chang's previous experience in sales should be an asset in his new position, and the move is part of an internal restructuring that hopes to consolidate operations.

Chang takes over for Jason Mackenzie, who had previously headed both marketing and sales for HTC. Mackenzie will now be North American chief after earning the position back in 2011.

Since his appointment as CFO in April of 2012, Chang has cut R&D spending and helped reorganize HTC's China operations, but has still hot been able to stop the bleeding. HTC shares have fallen short of expectations for nine consecutive quarters amid manufacturing delays and quality control problems.

Hopefully HTC will be able to turn things around next year, with rumors of its alleged HTC One flagship sequel set for an early 2014 release.
