Taiwanese smartphone maker HTC said its sales fell nearly 68 percent in June, its biggest slump in more than two years.
HTC's smartphones, once very popular, have lost their edge over the emergence of rivals such as Apple, Samsung Electronics, and more recently Xiaomi.
The Taiwanese company said its June sales fell to T$2.2 billion ($72 million), from T$6.9 billion a year ago and T$2.45 billion in May.
HTC has recently released new flagship phones but obviously the sales have been lower than expected. And the company's middle-end and entry-level models feature neither new specs nor high performance-price ratio.
Last week, HTC said it plans to slash nearly a quarter of its global workforce - or 1,500 jobs - through layoffs at its factory in Taiwan.
HTC has also sold its Pixel team to Google for $1.1 billion. More recently, the company combined its virtual reality and mobile divisions in an effort to refocus and sold its Vive team to Valve.
