Xperia restarts automatically!

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..
Hi... I did have the same problem n I couldn't find any solution... So i send it to repair...

[Q] Xperia Z wont stop vibrating

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?

No,not immersed in water.
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.
Thanks

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.

[POOL] About the touchscreen problem

I only discovered the touchscreen issue yesterday doing the test of the other thread. So, i would like to every z1 owner to answer this pool to know how bad things are and if we can try to find a solution, since i think Sony won't.
So, please answer the poll and post any useful information. I'll start.
My phone model is C6943, I currently don't use case and I'm using a screen protection. I can do the xperia touchscreen test without touching the phone body without problem and also doesn't have problem with pattern password.

Pool? I think you mean "poll"
My 6902 is completely screwed. At first I used a screen protector and the problem wasn't too bad. Then I removed it when I took the phone in to get another issue fixed and soon after that the problem got very bad. I was traveling so couldn't go back to the service center. Now it's a bit better, randomly works and randomly doesn't. When I was home in cold weather though it seemed a lot worse than it is now that I'm back in India where it's warm. Not sure if temperature is a factor, or could be conscience. But a few weeks ago it was so bad you couldn't type even a two letter word using Swype.
Also, I now have a part of my screen in the form of a horizontal line where touch doesn't work at all. No single touch and no drag. Completely dead. Taking it to the service center soon.

You should vote on the first option, then

Guys, check my post "News from whats is causing touch screen problem" to see if is your case!

It's not.
I got problem unlocking with patterns, scrolling pages and when I play some games after few minutes it stop working so I voted the first option. My phone is back to Sony, I hope they know what to do and at last it's Made in China.

Please, post if you use case and screen protections too. This could help understanding the problem.

Additional data : Z1 is being handled in a leather case, back and screen protector removed ( not the one with the logo, the plastic ones that makes your camera blurry )
Touchscreen problem seen in the game Alien Shooter, after some playing, the touch screen becomes less and less responsive ( i tap a button to shoot and use some onscreen joystick to move ) - both become unresponsive/less responsive as you play and the phone gathers some heat ( you can feel the touchscreen becoming hotter )

i have a simple tpu case, i had a bit of problem when playing all touch-based games (not ones with gyro like asphalt).
ever since i got the case it's better, i have the ASF and nillkin matte screen protector

I did not use any case just a chip screen protector. Anyway on a good healthy touch screen the screen protector should not influence the touch screen respond.

Hey guys, I have also this touchscreen issue, and I would appreciate if you give a feedback about warranty service, if sony accepted the problem and replaced a touchpanel or not, and also if the replaced touchscreen is better or not. I´m also thinking about sending it back for warranty repair.
I have also found that my phones touch screen is temperature sensitive, when it get cold or warm it just refuses to detect touch actions. Try it yourself put the phone into cold/hot water for 5 second, take it out, quickly clean the display from water and test the touchscreen. I first tought this behavior is normal and I didn´t cared until I started to play games. After 15minutes of playing the touchscreen bug every time appears. But also after a while its randomly disappears. So this thing is strange. (the bug appears identically also when I have my phone in a plastic case)

For me the warranty worked perfectly, i changed the phone 3 times until get a working one, i called Sony, discribed my problem and they changed for me, only 2 days for the change. BUT i recorded the problem and sent to them, so they accept the change.

Same here. I sent my phone back last week to the store where I bought it 2 months ago. They will send the phone to Sony Center but the time for repair or replace the device will not be 2 or 3 days but from 2 weeks to no eta. When the phone will come back to the store they will send the phone to me. I will post if the problem persist or not.

The problem is if they return a phone with the same problem.

They should be aware about this issue even on the new device so at this time they probably will check that but if they return a phone with the same problem, I will send it back again like many did. Someone had to replace the phone 3 times and I will do the same.

IYeah, you will be a long time without your phone though. I think I'll wait a bit since i rarely get the error and actually only when i try to reproduce it. How bad was yours?

I was able to reproduce the problem in many ways, Touch Screen Test, Opening the phone with Patterns, Scrolling Pages or with Launcher instead of switch the page it was opening the applications and at last when I was gaming at one point the touch stopped working and I had to wait, so this made my mind to send it back. On daily use was all ok but in some circumstances was frustrating.

i had the problem with cm11. and when I retored to stock then the problem was gone:S

I'm on stock and I got the problem.
Today for the first time I got the problem when writing on handrite. So I thought about using my phone warranty to get anotehr one. But it don't always fails when i do the method to reproduce it. So, how do you test if your new phone is working and how do you prove that it isn't? I mean what if i take the phone to warranty and it works?
And for you who already changed phone, it is working?

[Q] Touch malfunction

Hello lovely people of XDA.
Both my wife and me have the Z1, i for my part have experienced screen self cracking and now she is experiencing touch malfunction.
It acts out from time to time, making typing a pain in the a** and playing games even more dificult.
F.ex. if she presses the F key, it registers the D etc.
Ive made a video of this availible here:
http://youtu.be/McGnrGfVpq8 (Sorry about the music, but there was too mutch background noise).
This happens on the home screen, during Candy Crush(yeah i know) and during texting.
Ive repaired the phone twice(previous and newest firmware) via Sony PC Software and still its no good.
It even acted out on the first boot.
Has anyone ever seen anything like this?
Can't seem too find any solution.

Theres a well documented thread about touchscreen issues, I myself was one of the people it affected, your problem sounds slightly different.
The method to test was put the phone on a flat surface and make contact with the screen, move around and if you notice a break in contact then you more than likely have the bug.
Holding the metal frame of the phone in your hand eradicated the issue for some (me included) but it was certainly a pain.
My problem went away on it's own but some weren't so lucky.
Have a search for the thread in here, it's more than likely still active.
If nothing helps from that thread then it's more than likely a case of doing a warranty repair. (if it's the same issue)

Hello there and thank you for your reply.
As it seems to me there has been no solution to the problem, ive tried holding the phone without a case and the problem persist.
People are talking about the new update fixing it, but ive tried both updating and reseting the phone so that did not do anything.
It seems like the only thing to do is to send it in for a warranty repair.
With my self cracking the workshop told me that some of the frames where faulty placed in the factory and therefore might crack the screen after a long time under pressure.
Perhaps this is related somehow, though it feels and looks like a software bug.
Thank you for your reply, i'll be sure to keep a look out on that thread. (i found it now, but i could not find it before i posted this :S)
Thanks again

The kitkat update was rumored to remedy these touch screen issues. Have you updated? My C6906 was giving me occasional touch screen issues but they are non-existent after updating.
Sent from my C6906 using XDA Premium 4 mobile app

Yes i have installed Kit Kat, seemed to help at first but started acting out again the same day.
I even did a factory reset with newest firmware downloaded through PC Companion.
I'll keep looking around and post my findings.(If any)
Update:
So we both sent our phones to the service center and sold them right afterwards. Could not find a solution for the problem and the service center ended up replacing my handset and my wifes screen.
I now have a Nexus 6(it's so fantastic!) and she has an iPhone6 plus(Blaaarh...)...

No vibration at random times

Hi
I've noticed an odd problem the last few days, my phone vibrator suddenly stops working. It'll work for a bit and then suddenly stop and then start again without any apparent pattern. I downloaded the Sony Diagnostics app and it fails the vibration test when this happens - the problem is system wide.. The only recent things that I have done with the phone is wash it briefly after using it with dirty hands and changed my sim to go from 3G to 4G. I don't have any other issues with the phone, a restart doesn't always solve the problem
Anyone come across this before?
Edit: fix title

Bump..., it just happened again now

same problem
I have the same issue, but if i turn the mobile in landscape then tap the mic end of the phone whilst running vibrate diagnostic the vibrate comes back intermitently!

Seems like this is a common problem across the Xperia line of devices, there's quite a few threads about other devices with similar problems. Usually giving my phone a shake brings the vibrator back to life for a short while. It's starting to seem like it doesn't work more often than it does

Mine just stopped working today ugh. Let me know if you found a fix for this. Hope it isn't hardware issue

It must be a hardware problem if giving a shake brings it back, it sounds like there's something lose inside although I don't know if that's just how the vibrator is designed to give it space to vibrate or something else. Sony have recommended I send it in for evaluation, gonna be a pain

Giving it a shake does not solve a thing...
Still, instead of sending it to Sony for repair, I got a replacement from Amazon who is shipping the replacement before I return the faulty item...

I sent mine to Sony under warranty and they've replaced some components. I've not managed to start using it in full again but the diagnostic app hasn't flagged up any problems yet

Same thing happens for me.. I googled it and read a post somewhere and someone said it only stops working when he is typing and shaking the device provides a temporary fix...
Shaking it did work for me as well only for a couple of Mins then it stopped again.. I turned off vibration feedback on my keyboard and the issue has not returned.. So for me it seems to be a matter of rapid use

It happend for me 1 month ago after i listen music during the shower
Vibrate stop and not work until you shake phone.
Anyone could fix it?
I email to usa support and repair phone by their steps last night. But nothing changed.
Unfortaunatly my phone doesn't have warranty and even we don't have official sony office in Iran.

Important
any fix guys ??
i have the same problem !

Same thing here, keyboard kills it and shaking (massive shake from up and downwards) brings it back..
All is temporary of course..
Can some one please post updated information? Did you find software fix? Hardware fix helped?
Please note.

Also guys, lets find some common stuff maybe theres something we all did that caused it
For example i have:
1. Rooted
2. Recovery installed
3. Xposed installed
4. Modded dual speakers for calls
Mention if you've got any of these or other things that might be related..

I also have this issue. This issue has been occurring since the first Lollipop update. Never had a problem with KitKat.
My phone is stock with a full wipe install of 5.1.1. However, I did have all my apps reinstalled before the issue occurred. I never tested if this issue occurs with no apps installed as this is my only phone.

Mine stopped working also.. No shake or bump fixes this, not even temporary. This is so annoying, i never appreciated this feature so much, guess i took it for granted, but now that it's gone.. i'm constantly missing calls and texts..
Good part is now that it started falling apart for no reason, I might as well unlock it's BL and start messing with it

I have been having the same issue with my xperia z3. Vibration stops working when typing or spamming home and back button at random times . I can't see any pattern to it nor any reasonable explanaition to why this is happening. I have never let water come near my phone, nor have I ever rooted it. A tap on the bottom right corner always fixes the issue until the next time it happens. Has anyone found a permanent fix or what the root of the problem is? I feel reluctant to send my phone for repair as it would definitely take more than two weeks. I am also worried that once they open it for a repair it will never be waterproof again. As I can see, a large number of people are affected. Any solution?

Same problem here with Xperia Z5 Compact, but I also have another problem, because vibration does not work at all on vibration mode.
The phone is new, I have latest android update from Sony.
It is working when the sound is on, I have checked settings, and it says vibration is on.

Hi there, I have same issue with my Brand new Sony xperia E4g, i've bought it only for 1 week. I think this was hardware problem, when shaking my phone, it work, then when i turn it to some another positions, it doesnt work, or sound weird then doesnt work. Over all, it will work if i give a shake, then doesnt work in some specifical positions. Anyone have idea? should I take it to warranty service? Thanks

Same problem...
When vibration stop to work, you had to shake your device. So, the vibration will work again...
It's an hardware issue: I tried to flash another rom. I tried to root/unroot: it doesn't matter.
I sent my Z3C in warranty, but they didn't solve anything

I just had this problem a 2 weeks ago and today while writing message. 2 weeks ago, it just stopped working - so i rebooted device and it started working again. Today, it stopped working, so i just tapped back of phone, and it was working again. After a while it stopped working again, so i rebooted it and it's working fine for now but i saw a long time ago that sometimes that vibrations are randomly losing, and sometimes, that vibrations just feels and sound "weird". Specially when then phone is turned with screen upside down (that situaton happened to me every time when was laying in bed, on side or on back). I can't send it to support, i dont have any other phone that i can use as my backup phone... Ofc phone is rooted, xposed too, MM installed, and it had meet succesfully without any problem with normal water. Im washing it sometimes under stream of tap water, checking before that every side its closed properly...
