If Android updates are important to Android smartphone users, Lumia owners look forward for Windows upgrades. Ever since Microsoft demonstrated the Windows 10 Mobile features on Lumia 950 series, Lumia users have been eager to try out the new OS on their existing devices. Earlier it was revealed that Windows 10 Mobile will start rolling out in December but a new report says Lumia users will have to wait until next year for a new OS.

According to ZDNet's Mary Jo Foley, Microsoft will begin rolling out the Windows 10 Mobile for WP devices in early 2016.

"This November we introduced Windows 10 to phones including brand new features such as Continuum and Universal Windows Apps with the introduction of the Lumia 950 and 950 XL. The Windows 10 Mobile upgrade will begin rolling out early next year to select existing Windows 8 and 8.1 phones," ZDNet quoted a company spokesperson as saying.

Microsoft latest flagships, Lumia 950 and Lumia 950XL among other devices such as Lumia 550 currently run Windows 10 Mobile out of the box. But most of the devices are eligible for the upgrade and devices in the first batch include, Lumia 630, Lumia 635, Lumia 640, Lumia 745 and Lumia 830. The OTA update will continue rolling out to other Lumia devices including, Lumia 520, Lumia 532, Lumia 625, Lumia 720, Lumia 820, Lumia 920, Lumia 925, Lumia 930, Lumia 1020 and Lumia 1320, an earlier report said.

But Microsoft has already confirmed that Lumia 430, Lumia 435, Lumia 532, Lumia 535, Lumia 540, Lumia 635 (1GB RAM), Lumia 640, Lumia 640 XL, Lumia 735, Lumia 830, and Lumia 930 will be updated first.

Windows 10 Mobile has received a lot of praise for its worthy features such as Continuum, improved Action Center, new Microsoft Edge browser and more.
