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...

Help my xperia X1 is driving me crazy

Hi guys.
I have a wierd problem my xperia X1 touch screen keeps "failing" every 3-4days ok more explenation:
The touch function on the screen is not working this happens like every 3-4 days then i take out battery over night and the next morning its working 3-4 days again. Now the screen is not totally "failed" when its going into power save mode (the screen darkens) and i touch it it lights up again. Any idea what can be causing this? Oh and ive tried many different ROMS im now on the swedish stock R3AA....something rom and still the same problem, ANY help or ideas would be greatly appreciated.
I never turn it of (see below for explenation) can this be the problem maybe?
Oh and another problem i´ve had since the beginning is when i put in charger and the phone is turned off it emties the battery, seems like i have to charge it turned on, is this normal?
Hope somebody can help me
Sorry if my english is bad

Sounds like a hardware problem.
I'd flash the stock ROM and SPL and send it back to sony for repair because if this is happening everytime you flash then its unlikely to be a problem with the roms your using.
Give sony a ring and they should be able to help.

Yeah, definitely sounds like a hardware problem. I recommend contacting SE for repair. I hope your phone is still covered by warranty.

It is a badly problem,but I never have this problem,so I can't help U,sorry!

Xperia Z Touchscreen troubles

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
Hit thanks if I helped u.Sent from my Killer Xperia Z(C6602) using xda premium.

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.

[Q] x8 restarting after screen light timeout

My xperia x8 is driving me insane. Everytime my mobile's screen turns off/times out, after 2-3 seconds it restarts. I have flashed it's stock firmware i found on the web because i was dealing with the same issue before with the difference that before the flash, it wouldn't occur only on screen timeout, but it could happen anytime, usualy exactly after the boot. I also bought a new battery just to be sure because the previous one was a little puffed but that didn't help. Please help me fix my mobile please

Have you tried a different variation of the same stock firmware? If not I would give it a go. Idk what you have done, but a factory reset through flashtool should set things straight.

Remove your battery, check the little patch behind it for water damage. That is all I can think of. Because flashing those .ftfs is literally wiping your device as clean as it will go. So it sounds like something wrong more on the hardware side of things. Because if you have an issue in one ROM, if it is software related, it should not transcend into the other.

i had bought a new battery because the old one was a little buffed. the upside was that it kept going until the screen timeout, when with the old battery it would restart instantly after the sony ericsson screen. Could it be kernel issue or something like that? The device was my brother's who took care of it alot. he never droped it or anything. My last guess is that he charged it with a different charger not optimal for the device, that's why the buffed battery and the hardware issue! sounds plausible?

i just asked him and he told me he actually did, multiple times. Does this senario stand?

I think it may be probably a kernel problem....try using SEUS or Sony PC companion and flash latest firmware in your phone..i think it will work..:good:

It won't be a kernel issue if you have fully flashed stock .ftfs. But booting to the first Sony Erricson boot screen would usually indicate a kernel issue or problem with the chargemon.

pc companion was the first thing i tried, before buying a new battery.didn't make a difference. as i told before, is it plausible that the charging with a non sony ericsson charger caused the problem? i tried 3 stock roms, i don't think its a sw problem anymore. i am thinking of taking it to sony's tecs to give it a look but i don't want them to play smartasses on me so tracking the problem as much as possible would be a good start.

Yeah fair enough. I'm sorry but that is my sugestions exhausted I'm afraid. Buy yes, sounds more along the lines of a hardware issue.

[Q] Phone starts and sounds but screen remains black, with backlight on!!

Hello all,
My Xperia was in a serious bootloop that I couldn't fix, not with pc companion not with flashtool flashing stock roms. So I gave up and sent it to the closest Sony Mobile certified repair store, it took them one month to tell me they couldn't fix it, they said they opened it, changed the battery and it still had the same problem so they also gave up and gave it to me, they did say the problem could be the motherboard. I'm now living in Brazil and getting a motherboard for the c6602 is impossible first of all because the phone was never commercialized here (and importing is impossible, it'd take 2.5 months and they'd charge me 200% of the part price, unfortunately that's how Brazil works ). Something interesting that happened is that when I got my phone back they had solved the bootloop issue but they created another issue, the phone starts makes all the sounds the screen turns on BUT all you can see in the screen is the black color, so the backlight is on but nothing shows up.
Could I be able to fix this via software? or the only option is changing the motherboard (or maybe fixing something on it)?
If any of you knows how to fix this I'd appreciate an answer.

Because I sent it to sony and they said the problem was the motherboard and the problems the phone's been giving are pretty random, for example at the beginning the problem was that it had random reboot each one with more frequency, it when from that to just work with the ac adapter connected, it went from that to a bootloop of just showing the sony logo and restarting, after I got it from sony the problem is that it boots app (without needing to be connected) it makes all the sounds like it was working perfectly but the screen is ON but black. So because all this I'm convinced it's the motherboard.

I see changing the battery didn't fix your problem.
I think it's so sad that this phone with just more than a year of life are getting this serious problems and sony isn't doing **** to help us. They keps my phone 1 month just to tell me that it couldn't get fixed, they said they changed the battery and all but still the same problem. I've reached a point when I just don't trust sony anymore, I'm getting a galaxy s4 on monday but still I wanna fix this crappy-phone.

Well, in my case it happened out of nowhere, I wasn't doing anything special with the phone..., I'm thinking maybe restoring the TA partition would fix something? I don't know... I found the motherboard for 80 euros in aliexpress
