Xperia V standby hang, cannot wake up

anyone experience Xperia V cannot wake up or hang in standby?
it happens at nite after i sleep. but when i wake up, i press the power button several times but the screen doesnt on. notification light is working and blinking.
only way is to remove battery. its been happening everyday. even alarm is not working. checked my backup(sms, call log), it didnt backup. :crying:

I at least dont have that problem. Is your phone stock? Rooted etc?

I have this problem too. Not rooted. Probably, while charging this problem not appears.

Wrong section. This belongs in Q&A.
And for your problem, few users with.XT and XTX also reported similar problems. They are known as SoD (Sleep of Death).
There is no known fix yet. One users took it back to the store and the the Sony tech guru told him it's an isolated problem and he got a new one. So I suggest you go back to the store.
For anyone using adw launcher, one user reported that that caused his SoD. When he uninstalled that it was gone. Can be an app.
Try factory reset, and start first day without installing apps. And day by day add a new app, this way you can rule out if apps cause the problem.
Also format internal and external sdcard. Don't just empty them by wiping, you should really format, so no traces of possible app malfunction can be found back by the system.

Did I help? please press thanks button

after several days of testing, it doesnt hang on mine for 3 days already.
i guess its because there is a additional line in build prop "dalvik.vm.heapsize=36m" that cause this? this also cause my Need For Speed Most Wanted to force close too.
i also increase min clock freq to 594MHz.
also run TempMonitor(paid) on my notification bar.
not sure the above method works for most of u.. but try if it works.

I've got this problem since the first day. Got the phone, booted it up without even installing a sim card/downloading anything, plugged it into the charger, and it froze.
Since then it would go a few days without freezing, or it would freeze 3 times a day. The freezing always happen in standby mode.
Since it froze on a fresh system with no apps installed, it can't be app-related. There are users who have never experienced this problem, so I suppose the only way is to return the phone or take it to your local sony service center.
Normally it would just hang there and you'd have to pull the battery out. There was once where it hung and the phone got incredibly hot, and battery would be drained really fast.
Currently I am experimenting with keeping WiFi OFF, and surprisingly the phone has been fine for 4 days straight without freezing now. Its just something I'm trying and by no means this is a fix, but returning the phone to a sony store isn't an option for you, you might want to see if this works for you.

for those still having SOD, maybe u can try this. not sure it helps or not. because before i install jellybean, i review the code in build.prop first. so that is why it didnt happen on me for 2 weeks. well, i test it out yesterday.
use either ES file explorer or Root explorer, go to system -> build.prop.
find this line dalvik.vm.heapsize=36m, put a # in front of it to disable this code.
it could be because there is another similar code, thus conflict. u can find another similar line at the bottom of build.prop.
hope it helps!

Have you had anymore sod since disabling that?

Xperia TL (LT30at) sleep of death issues

So, just this last week after having my new Sony Xperia TL for a month I started experiencing the sleep of death issues, I haven't tried to do the restore via PC companion yet, if it does it again tonight I will. (I'll probably want to do that before updating to JellyBean anyways).
So far it's only happened at night, when on the charger for four+ hours, it's been hit and miss, happened two nights in a row, then worked two nights in a row, then locked up again last night.
The locked state; the screen is off doesn't respond to lock button, the notification light is blinking. I have to reboot it with the Volume Up + power button.
I thought I had fixed it by removing the PSM store (Installed that shortly before this fun started)..
Any other tips?
here's some links:
Xperia V sleep of death
http://talk.sonymobile.com/thread/60422?start=0&tstart=0

So, on Saturday (when I posted this) I disabled the ATT wifi hotspot software, and also in the apps section of developer options;
Checked "don't keep activities"
I'm not sure if I've solved the problem but the last two nights it hasn't locked up and yesterday the battery life was the best I've ever had.

I have only experienced this with wifi on. So long as wifi is off, it's not had a SoD issue. Irritating.

Seems legit

That's what happened to me just now. I checked "don't keep activities" but left wifi on. I'll see if it happens again. No point in having a smart phone if i cant use my wifi.

Did you have any more sod issues?
Since I've rooted and installed XperimenT version 1.7.1 I haven't had any sod.

Sod returned for me last night.
The only thing I changed yesterday was installing dead trigger. I rebooted into recovery and cleared the cache and dalvik.

I saw this thread for the v and noticed that this is also in our Rom.

I have had the TL for about a week now and have had this sleep of death happen twice. First time it happened i was charging it during the day with a little bit of use here and there. The second time it happened was overnight while i was sleeping. I was depending on the phone's alarm to wake me up, it never did. Woke up an hour later on my own and luckily wasn't late to work. I read somewhere else that killing active apps before putting it on the charger helps. It's been two night using this theory and so far so good. I am not rooted or unlocked. 1) Does anyone know if this is a hardware or software issue? 2) Should I return it for another device? I have a few more days to return it if need be. 3) Does the update to Jelly Bean bring a fix? Rumor has it March 12th is when the TL gets JB.
Oh and I have wifi on when I'm home.

No jellybean doesn't fix it. I'm running rooted jellybean (xperiment 2.0).
Friday night while charging it did the sod. I didn't change anything and its been fine the last four nights. I have no idea what causes it. I thought it was the line in build.prop, but not anymore.

Have you tried leaving wifi off?

Turned it off last night and the phone didn't SOD. The interesting thing is the night before I checked my phone about an hour before my alarm was supposed to go off and it woke up fine.
Any idea if it is wifi, why? Is there a build.prop tweak we can do to sort this out?

I have been keeping my wifi on for the last few days, and so far no more SOD. Only thing I have been doing is clearing any active apps before going to bed. As long as this keeps working, I'm good with it. Think it's been about 5 days so far. Will post if anything changes.
Sent from my Xoom using Tapatalk 2

If clearing active apps keeps it from locking up, one of the apps has to be the problem. Wonder if it'd be worth posting an app list?
Sent from my LT30p using xda app-developers app

I downloaded a system cleaner Friday and since I've run that there hasn't been any sod.
I've left WiFi on overnight all four nights.
Sent from my LT30p using xda app-developers app

So in my drunken state last night I forgot to clear my apps before passing out. I did not get a SOD. I probably got lucky. I also want to throw out there that the first week of ownership, I kept everything stock and only added my email apps since I heard jelly bean was coming out. I always do a factory reset after a big change in OS, so I didn't want to have to set up all my screens again. Anyway, I hot my SOD's during that time. So I think the issue is bigger than an app related one. Maybe the Jelly Bean update fixed it.

Seems like the consensus on the net is leaning towards Wifi setting "don't keep activities" for solving this. Just picked up my V last week and promptly had 3 SoD's after changing the wifi setting to "only if connected". Yesterday switched back after some searching and so far no issues. We'll se how it goes coming week.
BTW, my phone came with latest 4.1.2 and still has.

Since I've installed that system cleaner app, the phone hasn't locked up overnight.
I have wifi set to location mode, which seems to turn wifi off when the screen is off.
So, it's either a file problem, or a wifi problem.
Up time; 83 hours, xperiment 2.3.
I'd be curious if anyone with sod, flashed cm10.1 and still experienced them.

My guess is the latest Sony firmware has solved this problem. I haven't had any strange settings since anything above .141 and have not had any SOD's.

even i am using the TL... haven't experience a such issue yet.. but one thing.. mine gets heated very soon and battery drains really fast..can notice it clearly

Xperia TL "Android System" using tons of the battery.

So ever since the JB update, I've noticed that the Android System is using up a good chunk of the battery. The phone seems to be "waking up" constantly. Anyone else have this problem?

Let it sink for a week or so then it normally should go down.
Sent from my LT30p, 4.1.2 stock, DooMKernel v7,root access, unlocked bootloader.

Alrighty then. Thanks for the advice

I have had JB installed for almost 3 months now and it still sleeps very bad. Android system is around 11% in the android battery stats, i guess that's normal, but i just cant figure out whats waking up my device so often. I was so desperate to get it to sleep properly that i disabled auto sync, restricted background data for most apps and i disabled a lot of 'm. that didn't work. The highest wakelock in bbs is audioOut_2 but there's no real answer on whats causing this problem (for some people it's viber but i'm not using that) does any of you have the same problem? My drain on 3G is more than 3%/hour, that's way more than my xperia arc used to have.

I've been reading around forums and stuff. Trying to gather any information I can. From what I've read, it's just a bug in the Jelly Bean software. But of course, it could also be an app that is causing the wake ups.

In sound settings disable the last 4 options. Touch sounds and vibrate on touch and screen lock sound.
That will most likely fix your problem.
Please keep us updated.
Cheers!

What firmware are you on? Yeah, it sucks to have issues on a brand new handset especially at this price! Try to check if there's update available. I'm currently on .531 and haven't had any SOD so far.

I have experienced this bug on multiple occasions as well since I first got the phone. The phone randomly goes to sleep but the backlight stays on. Then I am not able to unlock the phone by pressing the power button and I need to hard-reset it (vol up+power) to bring it back to life.
For me it happened once or twice already even with Optimized backlight checked

happened to me when i was trying to share a dinosaur effect photo in the camera app

I actually experienced the bug on a few occasions right now and can't see a pattern. It doesn't matter if I have optimized lightening on or other functions it will just randomly happen on different occasions.
I have just flashed the newest .534 firmware and soon after the same thing happaned again so I guess it has not been fixed as of yet.

Arrgh! I just experienced this screen bug . And this is for the first time in last 4 days of owning the phone. It occurred while the phone was lying on the table (battery 9%) & I picked it up to make a call, but the screen won't light up. Had to hard boot using vol up + power button. Have not touched the optimised backlight option (still checked). Hope sony fixes this asap!

DAMN ! I'm on 14.1.G.1.534 and I just got this ! it hasn't even been 24 hours yet since I bought this phone. terribly disappointed.this could be such a great device. hope it doesn't keep happening - Sony Xperia Z1 C9602 - wtf sony.

I've had this happen twice since been on 534 firmware and had to use the red button to force the device down. Very frustrating but I think Sony will sort it and all will be good.

i have just about had enough of sony to be honest, i cant believe this is the third sony device in a row where there is something wrong with it, i bought the xperia z tablet, the touch screen was way to sensitive until an update fixed it, i bought the z ultra and returned it because of the sod, and now this, i turned off my phone last night as i didnt want to be interrupted, try to turn it on this morning, the sony screen comes up, then a blank gray screen, rebooted it a few times with no luck, the last time i just left it and eventually it booted to the home screen
and just now, i opened the camera app, just get a black screen, open snapchat to see if the camera works there, nope, it says error with the camera please restart device, so i do, only to experience the sod again...
honestly, with my experiences with xperia, i have had enough, i can put up with mediocrity only for a bit, if i keep on putting up with this crap, it makes me look like a fool
stuff you sony

Same here, terrible bug. Screen is actually there, but backlight won't turn on. I have to position phones screen towards the light source in order to go to the screen settings to uncheck optimised backlight option. If it is checked I have to uncheck it to get backlight to turn on and vice versa. Sony, fix that as soon as possible 'cause you got some pissed Xperia Z1 users here!

Im with a uk model and still on the original 518 version, and I've been playing it around for several days but no SOD issue

same issue with z1 C6903
i using z1 with .534 also facing same problem for past a week. it is dead when phone calls in. have to hard reset too. come on sony, this is issue is not new. we need a solution.
mind you, the phone is not launch in my country but i manage to use it.

Hi All,
I am from India and using Z1 (C6902) and its been 3 days since using my phone and thank god, no SOD at all...
maybe since mine is C6902 thats why ... i dont know but no SOD here till now

I have noticed this bug after i rooted my z1. (root via kingo tool), before it was working ok.
So when power off button pressed, screen still active...
after some tries, i have disabled auto-brightness check box. its now more or less working.

You're buying products that are relatively new (except the Tablet Z) and expect no bugs at all? LOL I think you need to step back and look at the whole picture. To be honest Sony releases updates in a fast and consistent manner so you should be happy that do this. Even the Nexus devices have their share of bugs and always see people react like bugs do not exist. There will always be bugs and what you want from a manufacturer is to release fixes.

Hi, me too having this bug. I had this SOD twice since last 7 days. Had to do a hard reset both the times. Waiting for sony to fix it. I think its the jelly bean bug and not the Sony's firmware's bug but can be fixed, i think.
I am from india and on the latest fw. 534.
Please let me know if there is any solution to this available in the market. Thanks in advance.

Eh.. To be honest this is not a feature but a small bug/error.
Normal the LEDS should go off when you turn your screen of while playing music. But for some reason the LEDS can stay on. Cause is unknown but it is not a real feature of the device

With Android 4.3 update, Sony started that the illumination bar (for music) will work even when the screen is off. So that's why I was a bit worried that it did not worked properly
