If you own a Windows Phone-powered handset and it has less than 8GB of internal storage, don’t expect it to receive the forthcoming Windows 10 Mobile software update. Microsoft has quietly mentioned in one of Windows 10 information pages that Windows 10 Mobile won’t be compatible with handsets that have 4GB of internal storage (or officially ‘at least 8GB’), irrespective of the presence of a microSD slot.
While most “modern” Windows Phone handsets won’t be affected with this hardware requirement, there are still a handful of smartphones that won’t be able to receive the update. The affected handsets include the Lumia 530, Kazam Thunder 450W, Kazam Thunder 450WL, Karbonn Titanium Wind W4, Celkon Win 400, iBall Andi4L Pulse, BLU Win JR LTE, and Yezz Billy 4.
Microsoft detailed in March that Windows 10 Mobile will be compatible with devices that have at least 512MB of RAM, and 4GB of internal storage (provided the device has a microSD card slot). But now it seems you need to have at least 8GB of built-in storage in the device. Our attempt to get a clarification from Microsoft did not bear anything meaningful as the company said it doesn’t have anything more to share as of now.
