Lumia 925 smartphone users who have subscribed to T-Mobile's wireless network service in the US can check out for the official Lumia Denim software update for their devices.

The much expected update has now started rolling out, according to an official T-Mobile listing which means that Lumia 925 users should get new OTA notifications.

Lumia Denim upgrade should be available in the form of a bulky 530MB file. Users can check for the software manually, as well as by navigating to Settings > Phone Updates, within their handsets.

After installation of Lumia Denim, the software automatically gets bumped to the newer Windows Phone 8.1 version bearing number 3051.50009.1451.0018.

Manually checking software version

  • From the home screen, swipe left to Applications.
  • Tap Settings.
  • Tap About.
  • Tap More Info.
  • Read the firmware revision number on the phone

Key enhancements brought by Lumia Denim, for T-Mobile-driven Lumia 925 users:

Cortana: Microsoft's personal digital assistant (PDA) is now active in more geographies across the world. Cortana brings features such as improved natural language, car kit integration via Bluetooth for contacts, snooze reminders and calendar improvements.

Live Folders: With this feature, users can create new folders by just dragging and dropping Live Tiles on top of each other, similar to how folders are created in Apple's iOS platform. Each folder can be renamed by tapping on the text field above the open folder.

Apps corner – A customised Start screen, where only specific apps or games are accessible can be created. This could be particularly useful for employers who have issued Windows Phones to employees.

SMS merge and forwarding – This feature allows users to select individual text messages to either delete them out of a messaging thread, or to copy and paste them into a new message in order to forward them.

Snooze Times – Snooze Time within the alarm application can be customised.

Consumer VPN – Privacy and security is ensured when using data while connected to public Wi-Fi hotspots or even with a home Wi-Fi.

Mobile Web Site improvements in IE – Users should notice comparatively faster download speeds and improved browsing experience within Microsoft's Internet Explorer (IE) web browser.

Store Live Tile (US only) – The Store Live Tile displays featured apps and games that are the most popular in the store, and also sorts games by user relevance.

Pre-requisites to install latest Lumia Denim update, within T-Mobile's Lumia 925:

  • 50% or higher battery life
  • Wi-Fi or data connection
  • 529 MB available memory (File size of update: 529 MB)

Lumia 925 can install the Lumia Denim update in their smartphones, and let us know about the software's functionality. However, if an error message indicating "'Update needs more space" is displayed during installation, then more space needs to be freed up by temporarily removing applications/media files such as videos and music.

To find out which are the apps consuming a chunk of the phone's space, head to Phone Storage.
