Nokia Lumia 925 and 1020 have a WP8.1 freezing bug, but a solution is on the way http://tinyurl.com/muuy2ju 答案揭晓了 之前休眠换不醒 要软开机才能用 果然是8.1的问题 难怪维修无用.... 简单的说就是CPU和电源出现了软件逻辑的冲突...? 预计在下次韧体更新时修复 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!
