Since the Windows Phone 7.8 update halt, there has been a massive amount of speculation as to what might have caused such a decision to be made. Now, there's some kind of build-up to that with a confirmation from Nokia.

Per reports, Nokia Russia has confirmed on its official Twitter page that the update was halted as Microsoft is performing some finalizations on the latest refresh.

"Microsoft decided to temporarily suspend distribution updates WP7.8 for finalization," Nokia Russia writes on its Twitter page in response to a question from a user if the Lumia 800 will be getting the Windows Phone 7.8 update.

"While this is common knowledge by now, Microsoft has been communicating very little around the Windows Phone 7.5 software update, making this the first official confirmation from some-one close to Microsoft that the roll-out has indeed been halted," WMPoweruser states.

The update, which was mainly intended for updating the start screen and lock screen, has proved to be pretty buggy, with Live Tile issues causing high battery and data usage for the users.

This is a brand new build-up to the latest on the Windows Phone 7.8 after it was reported earlier that Microsoft had officially confirmed that the company is seriously looking into the problems caused by the new Windows Phone update, and is on its way to develop a fix for the live tile bug.

"Yes.. We identified a minor issue where some 7.8 tiles stop updating and we are working on a fix now," Microsoft's Joe Belfiore, who leads the Windows Phone Team, previously confirmed on Twitter.

Microsoft Engineer Mark Chamberlain earlier noted that the Live Tile bug can cause two problems:

1. Live tile causing continuous web requests (and side effects such as battery drain)

2. Live tile failing to update.

It is also said that the first one can cause data overages and therefore be very costly to users.

"The fixes will be considered for inclusion in an update to the phone operating system. In the forum post above, several posters have been able to get around the problem by unpinning and repinning the live tiles. This might be a temporary workaround," Chamberlain wrote on MSDN.
