Xperia V spontaneous self reboot issue - Sony Xperia T, TL, TX, V

I'm using the Xperia V running the latest Jelly Bean stock firmware (see my signature). I while ago, my phone started to spontaneously reboot itself, sometimes during standby, sometimes while I had the screen on. I know that others had this issue as well, but none of the threads I found were really helpful.
I can't really explain this, as I didn't change anything in he past couple weeks. The only thing that happened was that I once dropped from about 1m in our living room, but I doubt that that would cause such a problem.
As for software, I'm using the Aviate launcher, and I have Android Tuner installed which helps to keep my memory free and reduce battery usage. AT is set to kill background processes when the screen is turned off, and important processes are all excluded from that. But again, I haven't changed anything in the past couple weeks before the reboot issue suddenly appeared, so I doubt it's any of the software I use.
So, does anyone have any ideas as to what might be the cause of this? It seems to happen less frequently when using WiFi instead of 3G. Might 3G be the cause? (I'm just guessing wildly, I really have no clue as to what causes what in an Android phone.)

My xperia t reboots whenever I switch it off and I have to force turn it off. Try a software repair

[Q] Galaxy Note not waking up?

I can't put my finger on this issue I've been having with my Note.
Don't get me wrong, this device is a godsend!
The problem I've been having is that sometimes when I take my Note out of my pocket and try to press the unlock or menu button it doesn't show anything on the screen. I've read about people having issues with delay before it pops up, but it doesn't pop up even after 10 seconds or a minute, it feels like the device 'hangs' or doesn't want to wake up. The only way I can turn the phone on again is by pressing the unlock button for like 10 seconds and the phone reboots.
I thought it was a problem with Green Power, I thought it maybe had issues turning off the wifi or data when the screen was locked and that the service would cause the OS to crash or 'hang'. When I look at my battery history after the reboot it shows that I lost a significant amount of battery (5-15%, depending on how long it took for me to 'discover' the crash) and there's a 'jump' in the graph.
Things I've tried:
Stock rom - problem persists
Different kernels - tried all the kernels available in the market including stock, problem persists
Add a bit of paper between back-cover and battery (to make sure it doesn't lose contact)
Checked if there was dust between battery connections
Tried different sim card
Tried disabling wifi and data all day (mysteriously persists)
DIfferent governors (ondemand and interactive) (the phone reverts to default governor after the forced reboot, normal? i have my phone set to interactive on boot, but somehow it skips that after the forced reboot)
I've attached a picture of the battery graph. According to the stats there's a 25 minute gap where the phone was 'stuck' and you can see that the screen was on and active for that duration.
There are NO funny apps running in the background, this is is a clean install with some standard Samsung apps frozen.
tl;dr version: phone randomly won't wake up; battery loss after forced reboot;
I might have found the issue myself. Now when I come to think of it, I think it always occurs after I've been in my car for like a 30 min drive... Maybe the phone is having trouble switching networks? Anyone know what might be causing this?
Or better yet, how can I research this issue? Can I enable some logging somewhere to track this?
I had the note for about 10 days and today, about 1 hour ago it happened to me for the first time. I tried the home button to wake the screen but nothing, tried the power , nothing and holding the power but nothing happened. I had to pull the battery.
I had this problem in the beginning, but no more.
It's one of two things, in my case. Restoring apps (with data) from Titaium backup, or SetCPU or both. Do a factory reset, reinstall apps without data. If using setCPU, disable it for a while to see if it happens again. It's been over a week and the problem is gone.

I was using System Tuner instead of SetCPU to freeze apps and change governor, maybe I've just been using the wrong app? I deleted it just in case. Will see if the problem persists, thanks!
The nasty thing about it is that it seems to happen randomly (but it most likely doesn't) and is pretty rare (happens once every 3 days).
Still, I don't like the fact of not being available for X amount of time, even if it's 30 minutes.
I'm on stock room and unrooted. Like I said first time it's happened.
i've had the GNote since 4 days now , and yesterday same thing happened as the device was in my pocket and i couldnt wake it up at all , battery pull solved it.
im on stock , non rooted
I can't believe that we are the only ones with this issue. Anyone else? OR better yet, how did you resolve it?
Dont know if this is the same issue as the streak had, but with the streak if you kept it your pocket with the screen facing your body this would sometimes happen. Flipping it so that it that the screen doesnt face your body in your pocket solved this issue.

Thanks for your reply. I did some research, and apparently it had to do with static being built up in the screen from wearing it towards your body in your pocket.
This issue was that you couldn't swipe the lockscreen cause the touch screen wouldn't respond. The problem we are having is that the screen won't even turn on and that the system locks up.
Same issue here with my 2 days old Galaxy Note, that's how I found this forum. In my case it went from not waking up occasionally to every time WIFI was ON (I did some experimenting with settings to see which one could be the one causing the problem). But then...occasionally it would not wake up even with WIFI OFF: very annoying. And this is my first Android, so I didn't have any custom anything, pretty much same as out of the box when I got it The only solution was to reset the handset. And definitely has nothing to do with having it in my pocket as I don't carry it in my pocket. Rang Samsung, they told me it was faulty, I returned it. Now I'm concern the next one is going to have screen issues? As so many people complain in this forum? we'll see.
My issues have been resolved after flashing AbyssNote 1.4 and when I stopped using System Tuner. I've started using Voltage Control instead and now I'm not even having problem @ 100Mhz undervolted 50mV from stock.
Same problem with my wife's Gnote, totally stock, just a small handful of apps installed. Happened twice, about a week apart.
She does a lot of travelling, maybe you're right about that. But it happens after she gets home when it's still OK.
Had the same same issue twice in two days and had to do a battery pull, just did a master reset and re -installed the applications manually, so far so go.
YOu guys think its a hardware or a software issue?
Hmm.. Happened to me too about three times in the last two weeks. I am on stock rom but rooted, and running Green Power. Hopefully samsung will fix it in the next updates. Seems like a software bug to me. Maybe not enough juice when in deep sleep?

Hello
its the problem of your kernel. try Abyys 1.4 and use XDA Superpower to adjust the CPU-Frequency automatically

It's very well possible that the stock kernel has faulty settings for the CPU. Haven't had the problem again with AbyssNote 1.4 and Voltage Control (even with custom cpu frequencies)
I just got my note today.
Battery in, turnt it on a few mins playing around.... the problem started
and hasnt since stopped...
Anyone tried contacting samsung about this?

at this point we're just guessing, there haven't been any official confirmations of the problem as far as i know.
But if it's so accute that it keeps happening all the time you must have a faulty device.. call samsung ?

[Q] Galaxy Note GT-N7000 crashing regurlaly how to find out the culprit?

My Note has started crashing regurlaly, I have had it since release and have a lot of software on it. I am not sure when it started happening but it is definatley getting worse as time goes on.
Is there any log file or event browser that can be installed to tell me what is causing the problem?
When I say crashing I mean literally crashing dead not a force close. I either find it in my pocket turned off and then have to hold the power button for an age to turn it on or sometimes it is sat on the desk and I suddenly hear the noise it makes when it re boots.
Any suggestions for finding out what the problem is that don't involve uninstalling software until the problem goes away?!
Thanks
Have you tried better battery stats? It gives a list of processes that have been running.
Definitely strange - do you have an anti-virus program you can run to see if it can help?
That sounds like a Sod (Sleep of Death) issue that's been reported many times b0t with no definitive solution of yet..
Some said changing modem helped, others with changing kernel or even ROM but no consistent solution across all users
Try to fix permissions through advenced menu in recovery but am afraid there is not much I can help with

Please post your current configuration Kernel, Anti Virus program if any, undervolting, overclocking ?
By any chance are you using easy task killer... if you are just change the auto optimize to nothing - I did that and it stopped sleeping...if your problem is persisting then you could just do a factory reset and use default settings...

My note recently started crashing as well, whenever i turn on my mobile data plan or the wifi it will crash right away
However this is ironic because when ever i put my mobile in charging mood than i have no problems at all.
So im thinking ,is this the battery problem or the software problem?

If the meter say less than 1850mAh in full charge than u need a new battery.

wifi issues with ics

Hey, my wifi always goes out and needs to be restarted while using ICS. at first it would happen like three times a day. now its a couple itmes an hour. it is very very very annoying. does anyone know a fix for this???
I don't have this problem, but do you have a wifi-sleep timer set up? Maybe an app is doing something?
No i dont. This issue was posted before in the threads but never had a solution. I always wipe EVERYTHING so i dont know why this happens with me.
Sent from my XT862 using Tapatalk
It's not just you. I get MANY wifi drops as well. I don't use it often, but when I do, I get a drop every 15 minutes or so. It happens very randomly: as in not when I'm loading a page, just randomly I'll see the logo go white then disappear.
My solution? A frustrated sigh and a switch of wifi on and off.

I did no have this problem on the AOKP 4/12 build, but do have it now on the 4/30 build. No idea why.
The audio issue is also ALOT worse for me. most of my phone calls do the silence thing where there is no audio. Today it caused me to run into alot of trouble. i hope these issues get fixed soon. I think it was the bluetooth updates in the changelog that caused the problems to occur more. As they are supposed to be bluetooth related. Unforunately i might have to go back to gingerbread
I am able to use 1x data & WIFI on ICS Rom only. Neither WiFi or Data works with Stock ROM.
Before It used to work in Stock ROM, but now it does not. So I am sticking to CM9
I have this issue too but I use juice defender. I only really use it for 2 functions
1. Enable WiFi when I'm home (constantly on) and disable when I'm away
2. Turn off data at night from 1am to 6am
when i flashed ICS the effectiveness is shady. A lot of times when i turn on the screen wifi is disabled but will reenable after a few seconds during the day. also at night sometimes it won't disable until later than 1am and will randomly enable and disable at like 4 am or something. sucks because i'll randomly get a bunch of notifications for emails twitter etc. and it will wake me up.

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!

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

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.

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.

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?

I downloaded a system cleaner Friday and since I've run that there hasn't been any sod.

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
