Few weeks ago, many users of Lumia 925 and Lumia 1020 reported a bug in their handsets that would freeze their device while trying to wake it up from sleep mode. The issue started after the devices were updated to Windows Phone 8.1.
Microsoft's Kevin Lee shed some light on the problems customers were reporting since updating to Windows Phone 8.1.
"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."
Microsoft has now acknowledged this issue, and promises to provide a fix soon.
“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!”
