Asus started its Zenfone series back in 2014 and has followed up with regular releases reaching a total of 80 devices under the Zenfone lineup but it seems that may soon come to a close. A new report from Taiwanese media TechNews suggests that Asus is pulling the plug on the Zenfone series. The report cites people familiar with the matter who claim Asus is undergoing an organizational restructuring.
Asus actually issued a statement about its restructuring back in June after its financial report indicated its first quarterly loss in over four years.
The report states that Asus will discontinue its Zenfone division and will move employees to the ROG Phone department. The restructuring process will also unfortunately result in cutting down the number of employees in the PC departments across Taiwan and China.There were plans to move some employees across to the Zenfone and ROG Phone teams but that will not be the case. Asus has not issued an official comment on the matter at the time of this writing.
Update: Asus has released an official statement refuting this report. The company is to restructure parts of its business, but the Zenfones aren't going away yet - you can read the statement here.
