While Microsoft has been revelling in the number of upgrades its Windows 10 operating system has achieved so far globally since its launch last Wednesday, we are yet to know for sure when the mobile version of Windows 10 will see the light of the day.
To soothe a few nerves, just a day after the official launch, Microsoft released a list of Lumia smartphones that would get the Windows 10 Mobile upgrade on first priority.
These phones were Lumia 430, Lumia 435, Lumia 532, Lumia 535, Lumia 540, Lumia 640, Lumia 640 XL, Lumia 735, Lumia 830 and Lumia 930.
Of these, only Lumia 640 and Lumia 535 are currently available in Microsoft’s UK stores.
If you thought that your Windows phone didn't feature in this list, don't worry. Microsoft has also confirmed that ultimately all Lumia phones will be upgraded to Windows 10. These will bring in existing phones like Lumia 735 and Lumia 520 which are still selling in the UK.
"This is an initial list of in-market devices to receive the Windows 10 update. It is our ambition to bring Windows 10 to all Lumia devices running Lumia Denim software, noting that some features will vary, based on the hardware specifications," it said.
Once available, Windows 10 Mobile will sport an Action Center, which will act like a hub of notifications across Windows devices. Using this, you will be able to view, respond to or dismiss notifications either on your phone, tablet or your PC.
You will also be able to switch between messaging platforms while chatting with people on your Windows phone. So far, SMS and Skype are fully integrated and Microsoft is working on integrating other popular messaging platforms like Facebook Messenger and Whatsapp.
Since all Lumia phones with varied specifications will be upgraded, the type of upgrade your phone will receive will depend on how rich it is in terms of specifications. While a Lumia phone with 512MB RAM and a screen resolution of 800x480 pixels can make the cut, Windows 10 will support devices with as high as 3GB RAM and 2560×2048 resolution.
Windows 10 Mobile will also support Qualcomm's processors like the Snapdragon 208, 210, 615, 808 and the latest Snapdragon 810 chip for faster operability. However, only 32-bit operations will be supported by the Mobile OS.
In terms of new features, the new OS will bring you HERE maps data, turn-by-turn navigation as well as Cortana integration. You will also be able to sync your music and playlists with OneDrive and browse the internet using the latest Edge browser.
Further updates on your Lumia phone will be Microsoft's new Continuum, new battery saving features, a universal Windows store, Face Detection feature within the built-in Camera app, removal of 3G download limits, VPN support as well as ability to convert and save web images as .png?width=700&quality=70 and .jpg?width=700&quality=70 images.
