HTC's prospects picked up this week when we learned the company had reportedly started a partnership with Amazon to develop the online retail giant's first smartphone. Unfortunately, the struggling phone-maker is finishing off the week with a bit of bad news. Bloomberg said Friday that HTC's vice president and head of global PR, corporate and internal communications Lorain Wong left the company today after taking the job just four months ago.

HTC's chief marketing officer Ben Ho confirmed the news, telling Bloomberg that Wong left for personal reasons, but will stay on as a consultant for another three or four months, likely while the company searches for a replacement. The Taiwanese smartphone maker has struggled to gain market share and build global brand recognition over the past year, posting its first quarterly loss ever earlier this month.

HTC has certainly had a rough summer. Following slumping sales even for the highly rated HTC One, the company saw an exodus of its executive team, including chief product manager Kouji Kodera, COO Matthew Costello, and HTC Asia CEO Lennard Hoornik. Now we can add Wong to the list.
