I am facing the problem recently last 2 3 days
my Xperia restarts automatically
sometimes there is 30% to 40% charging left still its shut automatically and never been start.. i have to change new battery
any solution for this or anyway to find the problem?
regards
anybudy would like to answer this please?
I'm having a similar problem...my x1 sometimes shuts down while in the middle of doing something, like opening apps, sliding out the keyboard or even navigating touchflo. I suspect it could be a battery problem, as someone in the forum discovered, having also shut down problems, that his battery is loose and the connectors are not properly met so he stuck a bit of hard paper to fix it, but I checked mine and the battery is not loose. I don't want to spend on a new battery if these shut downs weren't really cause by faulty batteries, so yeah anyone has a clearer understanding on this?
Hi all
I am also having a similar problem the past 2 days and as of now i cant use the qwerty keyboard because just as i begin to slide the qwerty out the screen goes black and the phone need to be rebooted.
I have just changed to Valkyrie 2.4 yesterday thinking that maybe its was software problem with Touch X but the problem still persists. Only difference is that with Touch X the phone would reboot itself.
Anyone else having any similar issues and what would the fix be, or shall i be off to my nearest service provider for repairs?
Thanks
Uhm.. about that problem when you slide it out and the device turns off.. i had that too and i send it in to repair.. it will probably be fixed under warranty, and stock rom or custom rom doesnt matter the problem was still there... and it happend to me 5 days ago..

'When i slide the thing out it sometimes restarts'
I used to have that with the stock ROM so this all might be more software related...
yeah I am having the same problem, No Water Damage btw. i found that if i sometimes in portrait mode if pressure is applied to the top right region, it will shutdown and/or restart. When I slide my screen up to landscape mode it screen is just black. I'm going to contact Sony Ericsson to see what they have to say about this.

It resets when the phone freezes. Sometimes it freezes so bad you have to manual reset.
My phone is doing the same thing but when i slide it up. The screen goes blank and then it restarts by itself. I never flashed my phone so I thought it was a firmware issue. I finally updated to the R3A firmware and lo and behold the same results, but instead it didn't restart, it just turned off or the screen goes blank. I've sent the phone to Sony Ericsson and they told me that I would have my phone back in 7 to 10 business days, but they're liars!!! It's been 13 business days and counting and no word as to whether the phone can be fixed or updates on status other than it's in "work in process". So then I called again today and complained to SE and the result is that they are "awaiting parts and Xperia parts are on back-order". After further probing SE told me that they would call me on Monday to officially let me know what the hell is going and why it's taking so long to repair my phone. I paid $800 usd for the phone and I would expect that their repair service would be a lot better and quicker than what it is! During my wait time for my phone, my PS3 broke down, I sent it in, got it fixed and returned already. That was within a week. There is definitely something wrong I tell you! They just need to send me a new phone!
Sorry about my rant guys, but I'm pissed!!!
My damn phone has the same issue, Until now, this hasn't been repaired for it's crack. And I'm almost out of warranty days, I think I bought it 2md day after the xperia was released. I'll try testing abou the presuure point though. I give you update
I did have the same problem..

I'm disappointed..
Well got the sleep of death last night.
Set the Alarm, woke up this morning after the alarm time to find the Z with the notification light blinking but otherwise completely unresponsive.
Had to do a power plus vol + reset.
Anything I can do to track down the cause?
Phone is rooted but bootloader is still locked.
Could be an application.

Well the only permanent SU grant I've given is to better battery stats.
If it happens again I may try revoking the grant and see if it makes a difference.
I have to add here, I'm regularly getting the Sleep of Death on mine, and it's not rooted, still completely stock... so I'm thinking it's not related to rooting or any kind of root-level process.
Initially I thought it might be to do with the new-fangled 'Stamina' mode - so that's turned off too now, but I'm STILL getting it - however, some days I don't - and there's absolutely no pattern to it at all.
My next step, though I don't want to do it, will be to take it back to factory settings (no installed apps, no accounts, no syncing etc) and see if I still get it then - if I do, then it'll be jolly well back into its little Sony box and back from whence it came toute-suite... (or quickly, if that doesn't mean quickly). LOL.
As an aside, on older Xperia models (was just reading) the Sleep of Death was a 'feature' but when connecting to USB, it was recognised as the QUALCOMM device - I've just plugged my death-sleeping Xperia Z into usb, and I get NOTHING.
Question: Does everyone get a green flashing LED when in Sleep-of-Death? Mine's always green, and flashing around 1Hz (once a second) for around 300ms (I would imagine, haven't timed it!)
Perhaps an Android Update will resolve it....!
Not sure if it will help, but on my old V the sleep of death disappeared when I switched off wifi
Sent from my gorgeous White Xperia Z
It's interesting you say that; as I was away a few days ago, and forgot my charger, so put the phone into Airplane Mode overnight, and for 2 nights, didn't have the Sleep of Death.
Tonight, I will try with no wifi, and see what happens.
Thanks!

Can I ask where did you buy your XZ? like all the people, who have this SOD problem, could you all write, where did you bought your XZs? may be it could clarify thing...
I bought mine in HK about a week now, and nothing like SOD or anything faulty, yet (touch wood, thank god). So I was thinking may be it was one of the earlier batches from manufacturer, that were defected.
Well, mine is UK based, and supplied by CPW (Carphone Warehouse) - fully unbranded, network independent device.
To add to the SoD issue, it happened earlier on without being on charge - and NO notification light flashing - it was, in effect behaving like it was turned off - no LEDs, no screen, no response to buttons. Hard reset (Vol Up+Pwr) fixed it again - 90% battery remaining when it happened.
It's gotta be down to some software related thing... surely...? Just - what?! Roll on 4.2.2

It does seem to be completely random some days I would get 2 SODs other times nothing for 2-3 days. It happened in the first 24hours I bought the phone. Mine was bought in Taiwan CC602, it's completely sold out so no replacement until the next batch arrives. However, the softkey reboot isn't such a big problem for me.
Stamina mode does seem to make it happen more often as well as task killers like ESTask Manager. Mine happened before root and after root. It has only happened when it hasn't been charging.

Mine was from Clove.co.uk, it's a sim free model.
I haven't had the problem since so hopefully it was a once off or at least is pretty rare.
I don't use stamina mode and I usually leave the wifi on.
Got SOD yesterday. At one moment i took the phone and tried to wake it up, but there`s no response from the phone. Set it in charging dock and wait for 15 minutes, still nothing, LED notification was totally off. After hard reset (3 times vibro) phone started fine. Stamina mode is always off, phone is rooted but the BL is factory locked. Bought it officially in Russia, color is black, 13W06.
After Xperia T and Xperia V, “Sleep Of Death” issue, has also appeared on the new Sony Xperia Z. There is nothing official right now, only some testimonials, from people who own the device, in forums and blogs.They experienced this issue with the Android 4.1.2 – Build 10.1.A.1.350 installed.
I have ordered Xperia Z and waiting eagerly for it.. but after knowing all these things.. I am very much worried.. I sold my beautiful Arc to buy this grand cell.. :crying:
This has happened to me too, the first time was within 24 hours after taking it out of the box. So far it has happened like 3 times in a week. 2 times it was overnight and the other time it was within 30 mins of the last use. I'm currently testing if turning wifi off before I go to sleep would make the problem go away but I'm not sure on that yet.

Official reposnse it that it has been identified. There's an update rolling out today but not sure if that's related or not?
Sony forum thread here
Hi,
Lately i am experiencing a lot of troubles while typing a message or just unlocking my lockscreen.
The touchscreen respods bad, sometimes it starts moving out of itsselve... Its really annoying to work with the phone like that...
Someone facing the same problems?
Suggestions? Fixes?
Btw. The phone is stock, nothing changed or replaced...
The onling thing i did was removing the shaterproof film (and my Sony logo )
Try repairing it with Sony's PC Companion or Sony's Update Service first.
remember to backup your stuff before proceeding.
Do full wipes.

Did you try to shut the phone down for 30 seconds and restarting it, seems to fix many unusual android issues.
I have noticed sometimes that my phone on the odd occasion does not repsond to screen press.
I am also experiencing the same problem.
Did a factory reset but still the same problem comes occasionally.. any solution ?

I've had this problem only sometimes when charging outside...When u feel that the touch isn't working as it should,put on your earphones and look out for a low buzzing sound..if u hear anything,then unplug the charger from the wall and check in another socket..hopefully the problem in my phone was that current was leaching onto the capacitive screen so if I touch just once,it registers a number of touches..hope this helps u get rid of the problem

That may be the solution to the problem you had but this isnt the problem here , it happens when whether the phone is charging or not and I think themichelanne is having the same problem.
Power off the phone with power+ vol up - wait for 1 vibrate followed by 3 vibrates and leave the phone then wait for 30 second before powering on, solved it for me....no problem in touch till now and i hope it does not come in future.
BTW This phone is really really full of problems.
Also happens to me when using some chargers
I bought my unbranded UK Xperia Z in Expansys, since I live in Portugal they sent a extra charger for the european standard socket. I had this exact same problem with it, the screen was extremely unresponsive and unprecise while charging. Now I use the charger from my old N900 and have no issues. Also, charging from a lower volt/amperage source like a computer I have no problems.
Since the capacitive screen is very sensitive, a low quality AC-DC adapter will generate issues (possibly due to the current/voltage not being 100% stable).

The issue is still unresolved, i did a factory reset but still the touchscreen stops responding ocassionally...
Need serious help guys...
Could be a bad screen protector.

me too
Im also experiencing the same problem. So annoying, especially while texting. Xperia Z's touch not proving to be how it should be.
This happens with this phone for me, and previous android phones. Usually its just the app open not responding to touch events, but my softkeys still work and I can force kill and restart whatever im doing. Sometimes I have to reset. It seems to be happening more frequently since updating to 67, but its not often enough really bother me. using a tool like romtoolbox to increase the amount of touch events android can process seems to improve it somewhat.

Have you found any solutions for this? I have been experiencing this since 4.2.2 update. I don't know what happened. Can you please explain what's wrong and what's happening? Have you got it fixed yet? My screen freezes frequently so I'm unable to use the phone.
I have been experiencing this problem since a long time. But I have found no solutions for it. I took out my screen protector and the freezing thing got to normal but still it freezes sometime, but more when the screen protector is on. I'm pretty sure this problem is caused by the screen or the android farmware. I'm downgrading my OS, please reply to this. Mine is C6602. C6603 doesn't experience any problems like that.
How I fixed my Xperia Z5 touch screen
Hi everyone,
So, my Z5 touch screen was not working at all anymore, I have tried every manipulation recommended on the internet but did not succeed to get it working that way.
Here is what I did to get it fixed eventually:
- Installed sony companion
- Launched the "fix software" program (I don't know the exact name of the program in english)
- Followed the steps (took a while, something like two hours)
Then my phone rebooted, but nothing, still the same issue. Tried taking off the sim card, rebooted and same problem. Then, I put it back in the phone, and for some reason, the touch screen decided to work again. Although, I lost a lot of data in the process, but worth it.
I don't know if it is a general fix, but on my phone it just worked that way. Although, I have noticed that my phone started overheating something like two weeks before the touch screen problem appeared, I assume those two problems are linked in some way. Still did not find any fix for the overheating problem except putting it under cool water or let it cool down for 10 minutes.
I hope I helped with my post, good luck for those who are experiencing this issue.
My Xperia Z started to act weird from two days ago, when it started to vibrate during all the time.
I restarted the phone,discharged the battery and recharged it again but it does not help me at all. It keeps vibrating even when the phone is turned off and it seems that it will never stop.
Did you guys had any similar issue?
Plzzz somebody help me:crying::crying::crying:
Did you tried a hard reset?(hold power and Vol Up at least 15 seconds)
And if i understand right, it vibrates too if you shut it down, or only from boot on?

I now that it seems crazy but the problem started in my pocket when the phone was together with my bio-metric passport for a couple of hours. Maybe it s caused from the chip of the passport?!
I want to share another fact with you:
Always before having this issue when I was pressing the phone from both sides with two fingers close to the menu button it starts vibrating but stops immediately after releasing it. I don't know if it happens to all Xperia Z mobile phones.

Doesn't happen on mine.
Maybe you should Send it to a Service Center or go to the shop where you bought it and ask for warranty. Did you Already tried to re-flash Stock Rom using FT?
Try flashing an old 4.1.1 one, it could be the NFC sensor. The downgrade will Also downgrade the NFC software. It may help.
If I should upload mine 4.1.1. ftf, just ask.

no, NFC does not interact with vibrator motor. That two devices is so separated
Sony must replace your phone in any reason. That's definitely sony fault.
Just had the same problem, My sony Z is a repaired one just over a month old. It is Always in a Leather Case. Just 15 min ago the Phone just started vibrating (thought it was a call) non stop. Turned the Phone off but didn't stop. Turned it on again but nothing changed.
meanwhile searched the web for solutions, only thing i could find that it was hardware related.
Since the Phone is little to big for my pocket i thought it could be from flexing the Phone or something like that. So i put it back in it's case, and put it flat on my hand and gave it a firm tap on the back with my other hand. The 2nd try was succesfull and the Phone stopped vibrating.
Checked if normal vibration still works and found no problems.
My experience with the latest Phones is getting worse with every model they (HTC / Sony) release. Feels like the phones suffer more and more from stupid (hardware) problems. Looks like the Urge of releasing a new model every half year is showing its flaws...
Mine vibrating too and getting worse!
The store guy told me it was the cover I had it in. Bollocks. The cover has been off for two weeks and still it vibrates! Seems to be worse if I charge it via a USB charger in my car. Related perhaps? I just tried the suggested holding down of power and volume and it has stopped vibrating. Fingers crossed! Glad I'm not the only one but need a fix
same thing here. my phone is vibrating RIGHT NOW!
my z3 is dual sim model the D6633. only 2 weeks old.
the phone first stop working on the touch screen. phone would not react to any finger. so when its locked, i can use the camera button to wake up and take pictures. still will not respond when i touch it.
then the phone getting warm at top area near the headphone.
so i google it how to turn off z3 with button, so i did, power+ volume
when phone turn back on, no screen. only a black screen with back lighting on. i can tell when i put phone right infront my eye.
then the phone start vibrate!!! none stop vibrate.
at this moment, i CAN turn off the phone with power+ volume but WON'T stop the vibrate.
really need a help, im in US and purchase this Z3 from NEWEGG and it is a DUAL SIM model, can i get warranty in SONY retail store????
GOD! why me
vibration problem
Hello,
I had the same problem.
Sony claims that there products are waterproof.
We as customers like that and want to try it out.
Maybe not in a swimming pool but at least clean it under de faucet.
That should be no problem, it is waterproof right!!!
After a while this vibration problem occur to your device.
Because none of these solutions help to stop this problem I decide to open my Xperia Z2.
My surprise was that I saw very small tracks of water inside!
Then I put it in the hot sun while it was open en the problem disappeared.
My conclusion:
It is NOT waterproof en a small short circuit causes the vibration problem.
Two days ago, my Xperia Z was on 1% battery, so I put it on charge. A few hours later, I go back to my phone, which had now turned off. I couldn't turn it back on, and I've also tried all the reset/hard reset ways. I left it on charge a bit longer (which all in all turned out to be 11 hours), still no success of turning it on. I took the charger out, then put it back in, which resulted in the red indicator light to come on (not flashing) for a minute, then switch off. But I still couldn't turn it on.
The battery is non-removable, which kind of sucks.
I've had my phone for about a year now.
I've read about this Sudden Death thing happening to the Xperia Z phones after the new software update, I don't know how true that is.
Apparently Sony has released a software update which MIGHT fix Sudden Death, but the thing is, because my phone is dead, PC Companion (updates your phone) won't detect my phone for update! So how can that even be possible?
Put a rubber band across it so that power and vol up are permanently pressed. Charge it that way for several hours and try again booting it
Look in the other thread about the same...seems like it has more importance than yours.. Hopefully you will get it working
My advice is just to leave it in the charger for some time... And hopefully it will work at some point

It didn't work, unfortunately.
I eventually sent my Xperia Z to Sony for repair. I have received an email saying that their engineers could not repair it, and have sent out a like for like exchange handset which I should receive in a few days.
that happen to me today, brought it in and there is a reset button right next to the sim card...very tiny, hard to see, use a pin and push it in...should reset afterwards...mine did ...hope that helps
Flash it
Hard reboot your phone and then flash a firmware using Flashtool if required. I have run into issues like this with my Xperia Z few times.
