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?

Help my phone keeps rebooting at random time when it is not suppose to

Hello i need help. My phone keeps rebooting itself at random times like playing a game,locking my phone,updafing stuffs and much more it doesnt happen all the same just 10/100 chance it does happen. I am using pandoriam 5.5 and was thinking of updating it to 5.7 but if the same issue happens in 5.7 i dont think i want a rooted phone anymore help????

Its nothing to think about... reflash and my gutt feeling say that the reboots disapear.
If not, via odin make a flash to stock.
If that didnt help.. it may be a hardware issue..
No worrys i think.

Hi.
Yes.. if you dont wipe you could inheret the fault.
Factory wipe and then install rom.
Your other hang problem could be fixed to i think. Who knows in the end?

Maybe I just found another possible cause for this long lasting problem. Sorry for bothering this old thread again.
I reactivate old but gold Samsungs with 4G by flashing the most recent stable cfw available. So I did with some SGS3 LTE and I was wondering, why every phone had problems with it. One just curiously lost EFS wich led to continously booting (could be fixed by restore), one had a sudden problem with the powerbutton (could be fixed by soldering a new switch), one just didn't like the SoC-standby (setting kernel to min. 800MHz fixed that) and finally today I found the last one to have a problem with the screen. When the screen blacks out due to energysavings primarly the system loses the connection to the digitizer wich is not the main issue. But 30 seconds after the display shuts off, the standby comes in not so handy and the screen gets a short circuit wich leds to a reboot. So I tried to exchange with a shattered display with broken touch and, oh wonder, everything is working fine. I then connected the suspected display to another mainboard and guess what? Yes, it rebooted exactly 30 secs after the screen blacked out.
Is anyone here still on this device and can replicate my sightings? I'd love to use /e/ on all of these cute little thingies and maybe someone else could do this also by just replacing the display?

...a few facts to add: I tried "keep display active during charging" (development options) over night connected to a powerbank and it stayed on. Just locking the phone made it go nuts and reboot 30 secs after...

Softkey Vibrate

Does anyone know what determines whether the softkeys vibrate on touch? Turning volume down to silent doesn't change anything but I've noticed that sometimes there is no vibration and I can't figure out the reason.

There is an option to turn it off in the sound settings,vibrate on touch.

But there's been many times when I've not been near any settings for a while and I notice the soft keys not vibrating.

I don't know if it's a software or hardware problem.can you try a factory reset?or repair the phone via pc companion.
Sent from my C6602 using xda premium

Firstly I'll monitor exactly what I'm doing when it next happens. I'm not rooted or unlocked yet so I guess it's nothing I've done (unless it's an app, if that's possible)

Right, so it's been almost a week. Unfortunately, I'm still having problems with no obvious explanation.
I soft-bricked my phone a few days ago so I've completely reset it. I was under the impression that it was only softkeys and haptic feedback that was being lost but today I'm sure a couple of time I've received messages without vibration (phone was in my lap and I can see the screen turn on but felt nothing).
My friend on his One X told me he often loses softkey feedback and haptics but that a message always brings it back. So until today I was putting it down to Jellybean (there seems to be a lot of S3 users with same issues too). Some S3 user reported that turning battery saving off has brought back feedback but I've not used stamina or anything like that, might there be something enabled by default I want to get rid of?
I kinda want to install CM10.1 to test on 4.2 but I'd need unlocked bootloader and I'm not sure how Amazon feel about that.
The motor seems to be ok... It sounds like a Bee or some paper trapped but from what I read that's normal because it's a thin phone. It's loud too.
When using the Service Tests area it seems to work without fail, but I need to test that after it turns off.

I'm still having this issue and I'm almost certain it must be a hardware fault.
Am I right in thinking that if I run a vibration test in the service menu then no system or app settings should prevent it vibrating?
Sometimes it fails to vibrate even in that test.

[Q] Logging? Phone shutting down (SwG 2.06)

Running flex's SwG 2.06. A few times since migrating to 4.3 my device has "shutdown" where it goes from launcher to an htc screen like when you power off/reboot the device. Earlier I let it sit like that for 5+ minutes as I packed my bag to hit the road and went down to my car. Still at the same screen when I got to my car. Had to manually power off and back on by holding the power button till it turned off.
I don't know if it's 4.3, rom or app related. Is there something I can run that wont destroy my battery that'll log or something to give me anything to diagnose my issue? I don't seem to have any abnormal battery usage... I think...
Thanks

Download alogcat from the playstore, or rewipe and reflash.

:( Problem : Screen turns on with a delay

Hi,
Been using this phone for over a week now and extremely satisfied.
Since a couple of days I have noticed that on a random basis whenever I press the power button to wake the phone, it takes a while to come back on. Sometimes it takes even up to 4 seconds to wake up. It's very annoying.
What I have observed is off the phone is unused for a while then it happens more. If I wake the phone immediately, then it wakes up very fast. Sometimes even on an incoming call its delayed for a couple of seconds though not everytime.
I have flashed the official 534 official Generic Indian FTF twice now and updated to 257 but still this issue is present.
I am downloading RomAur as I type, will flashing it help?
The phone otherwise is super snappy with no problems.
Any input will be highly appreciated
Thanks in advance
cheers!!

No flashing it won't help.. You need to unlock bootloader to flash it and if you don't backup TA, bye bye camera.. I suggest you flash stock ftf and do a factory reset... There might be some app slowing down the wakeup.. I haveDS battery saver and it can delay screen wakeup to reduce load on CPU...

I was able to flash RomAur without unlocking the bootloader, but it didn't help. The problem was my bad memory card, removed it and the problem is gone now. Thanks for your input
