If you own a Windows Phone 8.1 device from UK-based Kazam, you are going to be stuck with using that OS from now on. A Kazam rep has confirmed that the company "won't upgrade existing product" to Microsoft's upcoming Windows 10 Mobile.
The news was reported from WMPowerUser but the Kazam rep did not offer a reason for this decision. Kazam released its first Windows Phone 8.1 device, the Thunder 340W, in late 2014. In 2015, it began selling two more phones with the OS, the Thunder 450 and 450WL. All of the phones are in the budget to mid-range variety.
The good news? Kazam has already confirmed it plans to release new smartphones with Windows 10 Mobile pre-installed sometime in the future. That was echoed in the statement sent to WMPU as the Kazam rep stated that "all of our new WP devices will have it going forward." Details about those devices have yet to be revealed.
