While the Redmond giant had at its Wednesday event announced that all modern Lumia devices will get update to Windows 10, it has now added a few caveats.
On Thursday, the Microsoft Lumia Conversation blog published a Q&A with Chris Weber, Corporate Vice President of Sales for the Microsoft Mobile Devices group, noting that "not every [Lumia] phone will upgrade or support all possible Windows 10 features."
Answering a question about which of "today's Lumia devices can be upgraded to Windows 10", Weber said that Microsoft's goal is for "majority of the Lumia phones running Windows Phone 8 and 8.1."
"We're making it as easy as possible to get Windows 10. Windows 10 has been designed to run well on today's Lumia phones. Like any upgrade to a new platform, not every phone will upgrade or support all possible Windows 10 features, and certain features and experiences will require more advanced future hardware. Our goal is for the majority of the Lumia phones running Windows Phone 8 and 8.1 to join the Windows ecosystem along with an expected hundreds of millions of PCs, tablets and other devices running the next generation of Windows," said Weber.
With the usage "today's Lumia phones", we can expect several phones will not qualify for the upgrade. A significant number of Windows Phone devices, some even more than two years old, have received the Windows Phone 8 and Windows Phone 8.1 upgrades, but their hardware may not support the minimum requirements for the Windows 10 upgrade.
Although Weber didn't share any list of devices that will get updated to Windows 10, he pointed out that "the budget-friendly Lumia 435, the selfie-happy Lumia 735, or the gorgeous gold-edition Lumia 930" will be able to get update to Windows 10 as it becomes available.
