HTC has been on a tear this year, registering month after month of record revenue thanks to strong demand for its Android-powered smartphones. The Taiwan-based vendor saw six straight months of record revenue until October, when it recorded revenue of NT$44.11 billion, a 2.8% dip compared to September. Revenue was up 36% over October 2010, however. Apple’s iPhone 4S sold more than 4 million units during its launch weekend alone following the device’s release on October 14th, and while the new Apple smartphone may have had some impact on sales of HTC phones, the company had already issued light fourth-quarter guidance during its third-quarter earnings report. HTC clarified on Monday that fourth-quarter sales would grow between 20% and 30% compared to the same quarter last year, but would decline from the NT$135.8 billion reported last quarter.
