Few weeks ago, several Nokia Lumia 925 and Nokia Lumia 1020 users started to report a bug in their handsets that would freeze their device while trying to wake it up from sleep mode. The issue started only after the said devices were updated to Windows Phone 8.1. Microsoft has now acknowledged this issue, and promises to provide a fix soon.
The company announced the availability of Windows Phone 8.1 in July. The update arrived on Lumia handsets as “Lumia Cyan” update which bundled Windows Phone 8.1, as well as several Lumia exclusive features. The update started gradually rolling out to several handsets across different regions and carriers.
The aforementioned bug, however, only affects select Lumia 925 and Lumia 1020 handsets. Those who were affected had no choice but to soft reset the phone to turn it on. A Microsoft representative Kevin Lee, who is the Partner Director of Program Management, however, assure users that they have found the issue.
“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.”
He further added, “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!” He is likely talking about the Lumia Denim update.
