Nokia has pushed a Windows Phone update v.8.0.10521.155 to Malaysian Lumia 1520 users. The update contains general performance and usability improvements. The Lumia 1520 was the first Nokia product to come with Lumia Black (Windows Phone Update 3), which brought many UI enhancements, improvements to camera, Glance Screen and more.
Update v8.0.10521.155 was pushed to certain markets several weeks ago, and to Malaysia on March 2. There is no changelog available so we’re not entirely sure what the update has brought.
To check for updates go to Settings > Phone Update and tap the Check for Updates button.
