Chang stated he chose to resign to pursue his own "personal career plan".
According to HTC, Chang joined the Taiwanese smartphone brand in April 2012 as chief financial officer after leaving the U.S-based investment bank Goldman Sachs.
The note to the investors revealed that there is no replacement for Chang as of the moment, though the status will likely change anytime soon. Now it looks HTC is going to be losing another member of its ranks, the company's president for Smartphones and Connected Devices, Chialin Chang, stepping down. The deal also granted Google a non-exclusive license to use HTC's intellectual property. HTC, for one, is gearing up for the release of its new smartphone that is expected to compete head-on with the bigger tech players in terms of specs and features. Google has been serious about making its own hardware with its Pixel smartphones and other devices, while HTC's efforts in the smartphone market have continued to dwindle despite releasing formidable handsets. This affirms that HTC is no more the company it used to be, at least in term of sales. Hopefully, the company will find someone who can help HTC revisit its glory days when it was one of the top smartphone manufacturers in the world. The new smartphone, which is in the headlines as the HTC U12, is likely to support 5G connectivity and could come with a Qualcomm Snapdragon 845 SoC. Instead, the upcoming Android flagship phone will be announced sometime after MWC 2018. The reason given for the resignation was simply "personal career plan"; the resignation comes just weeks after Google confirmed that it was buying the smartphone and connected devices section of HTC.
