Lumia Denim update is expected to fix freezing issue on Lumia 1020 and Lumia 925. Lumiaconversations

The Lumia 1020 and Lumia 925 are suffering from a random freezing issue after the Windows Phone 8.1 update.

The bug has affected Windows Phone devices on developer preview version as well as those running with stock carrier update. Thankfully, Microsoft has acknowledged the issue.

Kevin Lee, partner director of program management at Microsoft, in a posting at the community, has stated that the issue is due to a power regulator logic failure and there could be a number of reasons for the device failing to power up the CPU and peripherals.

Microsoft has promised to release the next software update with the bug fix for the issue, soon. Microsoft's next update will be Lumia Denim, reports WMPU. Here is Microsoft's statement regarding the bug fix update.

Hi Folks,

I'm sorry we've been dark - I work closely with the Lumia engineering team that's working directly on this. Trying to shed a little light on this...

Beginning in early September we started to receive an increased number of customer feedback regarding Microsoft Lumia 1020 and 925 device freezes. During the last two months we have been reaching out for more and more data and devices to systematically reproduce and narrow down the root cause. It turned out to be a power regulator logic failure where in combination with multiple reasons the device fails to power up the CPU and peripherals after idling into a deep sleep state.

I am pleased to pass on that we have a fix candidate under validation which we expect to push out the soon with the next SW update!

Appreciate your patience.
