Microsoft and Nokia have officially confirmed that the distribution of Windows Phone 7.8 to older Lumia devices including to Lumia 800 has been temporarily suspended. The reason for the suspension of update was given by Microsoft’s Windows Phone program Manager, Joe Belfiore had given that the company had found a minor issue and was working on a fix. The problem with the 7.8 update was that of strange behavior of Windows Live Tiles.
The Windows Phone 7.8 update started approaching the market on 31 January 2013 on Nokia devices is more of a skin-deep update rolled out to Windows Phone 7.5 users bringing in some features from Windows Phone 8. The main reason this upgrade was necessary because smartphones running Windows Phone 7.5 cannot be upgraded to Windows Phone 8 even no matter how good the hardware specifications might be because the former was built on a different platform than the latter.
This update added some new features including a new start screen with resizable live tiles, as in Windows Phone 8. It also brings Windows Phone 8 branding to existing Lumia devices on the splash screen and icons for Games, Office and Windows Phone Store. It also doubles the number of theme and accent colours to 20 and adds other new lock screen features: the option to automatically display the Bing Picture of the Day plus the ‘A1B2C3′ PIN/password challenge to prevent accidental device wipes on phones connected to Exchange accounts.
