Japan's VAIO Phone Biz, a Windows 10 Mobile smartphone that launched in Japan earlier this year, won't be getting the Windows 10 Mobile Anniversary Update for a little while.
According to a support page on VAIO's Japanese site (via MSPU), the issue is related to Continuum support for the Phone Biz. The page adds that VAIO is working with Microsoft on this bug and will roll out the Anniversary Update to the Phone Biz when the issue has been resolved.
The VAIO Phone Biz launched in April for the price of ¥59,184, or about $530. It has a 5.5-inch full HD display, a Qualcomm Snapdragon 617 processor, 3GB of RAM, 16GB of internal storage, a 13MP rear camera and a 5MP front-facing camera. It does support Continuum via a wireless connection to a display, but it does not include support for a hardware dock. VAIO has no plans on selling the Phone Biz outside of Japan.
