Xperia z alarm when phone off

Some Xperia V units suffering from ‘Sleep of Death’ bug

A number of Sony Xperia V (LT25i) owners are reporting that they are suffering from a Sleep of Death (SoD) bug on their handsets. For those that don’t know, ‘Sleep of Death’ refers to a problem where a user will have trouble waking their smartphone from a standby state – often users will have to remove the battery and restart the phone to get it to work again.

There are dozens of reports over at the official Sony Mobile Talk forums of users complaining about very similar issues. Reports of this problem first started around the phones release, in early December. Since then, new people have steadily been chiming in with their own stories of woe.

The Sony Xperia Support team appear to have gone AWOL since their last post on the matter on 10 January. At that point they commented. “I’m just posting to inform you that this is being investigated with high priority at the moment. I will get back to you all as soon as I have more information or even better a fix. ”

Their doesn’t seem to be any fix for users right now. Some users report that upgrading to the latest firmware (9.0.1.D.0.10 ) helps, but others are saying it makes no difference. The support team, earlier on, suggested booting the phone in safe mode. but many users say this also doesn’t resolve the issue.

It seems that this bug affects at least a sizeable minority of Xperia V owners judging by the number of comments on the support forum thread. We hope Sony Mobile comes back with a proper fix for all Xperia V owners, for what is one of its current flagship handsets. We also hope no such issues plague the upcoming Xperia Z, especially after garnering much positive attention since it was unveiled.

Comments from Xperia V owners suffering from ‘Sleep of Death’ bug

“I got my Xperia V a couple of weeks ago and I am really pleased with it. I only have one problem which I do not know how to fix. Sometimes when the phone is in standby, I cannot turn it on again by pressing the power button. There is absolutely no response when I do so. I can see the phone is still on because when I have a message, the LED is blinking. The only thing that works is taking out the battery and power it back up. I think it has happened to me 4 times over the past 2 weeks.”

“I upgraded my Xperia Arc to Xperia V a week ago and the first days it worked perfectly. The last two days I noticed that the alarm did not ring and then when I investigated the phone I could not start it with the on/off button on the right side. I could see it was on since the light blinked blue for new message but I could not start/open the phone. I had to remove the battery and put it back and then the phone kicked on.”

“I need to report yet another freeze-in-standby-problem. It usually happens during night-time while my phone’s out of use for many hours. Only way to get going again is to re-insert the battery. This is a serious joy-killer on an else absolutely wonderful phone. ”

“I have woken up late, and hence came to work late 3 times, due to this “sleep of death” problem on my Xperia V. Can’t imagine after so many years using the phone as alarm clock, now I have to rely on the mechanic alarm clock again.”
