Xperia Z3 doesn't stop rebooting - Xperia Z3 Compact Q&A, Help & Troubleshooting

That's it. My Z3c reboots over and over again, until the batery is dead. No idea what can I do. The whole problem started because was not conecting. I have tried installing new firmwares but dind't help.

This very much seem like an hardware issue with your phone if installing a new firmware didn't resolve your problem.
What were you doing with the phone when the issue started to happen, and have you ever submerged the phone in water?

[Q] My xperia TX sometimes cannot wake up

Just bought a xperia TX few weeks ago
But I feel that there are some problems during I use.
Sometimes when I want to wake it up from standby mode
It doesn't wake up and the screen keeps nothing appears
But the notification light still works, so that the phone should still working and not ran out of battery
The solution I use is pull the battery off and place it again....
This happened about 4 times in a week...
My phone is 7.0.A.3.197
even it is rooted or not, the situation still here.
Is there any idea to solve it?
Had exactly the same problem with my T and tried every posible documented solution but nothing worked. So I just dropped my T to service yesterday and expecting to collect it tonight, after that we'll see what the problem really is. The guy from sony said they have had this issue in the U and Sola but nothing reported so far on the T. He claimmed however that for this issue is to be settle in first quarter 2013 via update of course, in those devices. But did not mention something about this in the T.
In anyway I don't feel like is software related, my bet goes to a hardware issue in some unlucky devices.
I started a post here called Xperia T SOD so keep an eye on it as later on I'll report my findings after the Sony Service job.

Sorry for push back the post.
I noticed that this situation happened when I connected to my home's wifi for a long time.
Because during the holidays, the times of my phone suddenly dead from sleeping mode is increased.
I am using mobile data at outside and Wifi at home, and the situation always happen at home, so that I think that the phone maybe dead from sleeping mode in a significant condition, that means the Wifi connection.
I tried to set the wifi keep on during sleep only when plugged in, then the the situation haven't happen again in previous two weeks!:laugh:

[Q] Sony Xperia T keeps restarting

hi,
Ive got a problem with my SXT. It kept restarting randomly during the day. I rooted it before and was everything fine till one day. Now I cant use my phone cause it keeps restarting all the time. When i switch it on i cant evan touch the screen without restart. Ive flashed few roms already, stock ones either and nothing helps. I also wiped all data, cache etc.
Really strange problem cause phone works fine when its charging.
Has anyone any idea?
ps. repair via pc companion didnt help too.
Thanks.
Does your phone have CWM? Just wipe cache and dalvik cache
Or you can repair your phone by using PCC/Update Service

did you check the sim card ? , sim card broken also cause automatic restarting
sorry for my bad english
Hi,
No, I didnt check it. Will do ASAP.
btw. Ive updated my fw to the newest one.
edit. sim card seems to be fine. :/
SIM card placement causes random restarts. Make sure it's on their seated properly and securely.

Did you cut your sim down to size or is it a factory micro sim? I know cut down ones mess it up.

atleast you have try all, nothing work. thats the best choice u have, send it to sony center:good:
Having the same issues
Only my phone is also freezing even after repairs using both the PC Companion and also SEUS, reformatting my sd card and also a return to Sony.
SIM card is original Micro Sim It is crashing anything from 5 to 10 times a day, with data and/or wifi turned on. Even with the data and wifi turned off I am getting restarts.
Wondering if returning it to Sony did you any good dajbanana? or whether I need to raise the phone as faulty to the point it needs replacement with Sony GB?
you are using a kernel what is not ment for the rom? i mean, using a cm10 kernel on stock rom for example.

If that was the case it wouldn't even boot up, and also he would not be able to repair using pccomapnion or seus

What was the outcome in the end? It looks like my T is suffering the same symptoms :crying:
Battery is dying. Battery management of this phone is one big crap.
Only solution is new battery.

or a new phone?
So the only solution for this issue is to send off to Sony for them to replace the battery components? I had a strong feeling it may be battery related. First(and to be last) phone I have owned which hasnt had a removable battery. But then I wasnt fussed as I have never had to replace a battery on a device in my life!
I am with you. My last phone was Motorola Photon, my friend still has it with original battery and it is 2 years old phone.
This is big fail in mobile device.
Even new battery jumps down by more than 100mV, when you make a call for example. I will try again when it reaches 3,7V (nominal voltage).
It is even worse. About 160mV dropdown when starting a call.
i think the battery was a problem for me to it crapped out and i think thats also a reason why it wont work so goodbye sony hellooooo google/lg :laugh:

[Q] Xperia SP reboots when WIFI is on and screen goes to sleep

Xperia SP on stock 4.3 ROM. Bootloader is locked and the phone is not rooted.
Issue started a few days ago, whenever the screen goes off while the WIFI is on the phone reboots. Once it reboots, if I don't switch WIFI off the phone keeps rebooting and warms up. While the screen is on, the phone works great, no issues at all. When the screen goes off, it reboots.
What I've tried so far:
Boot into safe mode, same issue
Repair with SUS, same issue
Downgrade to stock 4.1, same issue
Upgrade to different stock 4.3, same issue
Is anyone else seeing this? Any ideas for a workaround?
Thx
I can only suggest go to a repair centre and ask for a refund or fix. This sounds like a hardware issue and you've tried like all the possible solutions there is nothing more you can do.
You can try any custom ROM.. But I dunno if that helps.

Yes, you are probably right.
I noticed today that it reboots while charging too, with or withouth WiFi on, so it looks like a hardware issue.

[Q] Anyone experiencing SERIOUS crashes after the Z1 sound-fix update [on stock]?

Hey XDA'ers,
First off, in case anyone mentions that I have to use the search function of XDA: I did an I couldn't find any thread with this exact question, so I presume it's okay. Now, ever since I've installed the sound fixing update Over The Air, my phone crashes quite often. This happens most often when I play music through my amplifier with a standard 3.5mm cable. There seems to be about half an hour in between but it varies. The music would suddenly stop and my phone won't turn on anymore, with a completely black screen. If I then wait a little longer, the phone restarts and it does not even require me to enter my SIM's PIN code which is odd on its own, as if it doesn't fully crash but reboot on its own or something. I thought it only happened while listening to audio, but it just happened again when I only tried to open the Album app, I got the message that the app crashed and while that message was popping up (it was still a bit transparent) the phone froze and rebooted.
Now, I'm used to regular apps suddenly crashing with my Xperia Z1 which is weird to begin with, but opening these apps again just gets rid of the problem. It was only a minor annoyance so far, but it did make the Z1 look like the firmware wasn't stable at all (multiple apps keep crashing, even the front camera today as well...). But now that the phone even reboots at least every day, the minor annoyance is becoming a major annoyance. I really don't want to reinstall the firmware because it takes too much time to reinstall all the apps and data I have on the device.
So I'm just wondering now, am I the only one with this issue? I don't suppose there's an easy way to fix it without factory resetting or reflashing firmware. And by the way, I'm completely on stock with my device. I haven't rooted, unlocked the bootloader or anything. If you've experienced this as well, please let me know. Maybe we can dive into it. Have you for example reset factory settings with the issue reoccurring? Have you flashed the firmware yourself and did the issue perhaps stop? I'd love to know.

Try repair the Z1 via PC companion, you will not lose any data to do that and maybe will fix the problem, otherwise a Factory Reset will be recommended.

Wait, this PC Companion repair does not erase any kind of data on my phone? Are you sure?
I thought it would just reflash my firmware and basically do a factory reset. Which is not what I'm looking for.
Have you not experienced any app crashes or rather sudden phone reboots?
I have the same. Sudden reboots. It was the same way when I was rooted on the.. 757 firmware.
I did the repair with Sony update. Still the reboots but even more random. When rooted it usually rebooted when using camera.
Also the touchscreen doesn't react like normal sometimes. Not that often it happens but it happens.
Reboots about once every day and at completely random occasions.
I'm guessing it's the firmware, just have to wait until a stable firmware comes. Until then we are stuck beeing testpilots for Sony developers.

I only had some weird problems with the camera but only at first after that no problem

why you are afraid to start from 0 ... I can not understand ... too much of laziness??? your stories of wanting to keep your data, tends to cause bugs that are not on a clean system...
You can save the very important files on your computer... And restore the principal after...
You should atleast try a repair but for me everything actually got worse after the repair.
Someone at Sony replied to me with "have you tried your phone without the sim card". Are there known issues with simcards making our phones crashing I wonder?

[Q] Xperia V keeps on rebooting.

Hey XDA,
I hope you guys can help me with this annoying problem I am having with my Xperia V.
Two weeks ago I flashed UniQue3 on my phone since I was pretty satisfied with the previous version and I wanted to try the new one. (I had stock installed before that, since it had android 4.3).
Then crazy stuff started happening: My phone would just reboot when I was typing a message or browsing the web. No biggy, this happened before sometime as well. This time it was different. It happened constantly. I could not use Whatsapp for longer than 5 min before my phone just rebooted. Funny thing is this only happened when I was not charging it. It happened while charging it as well, but not nearly as often, maybe once every 5 hours.
My phone would not shut down either if I did not use my screen. I can listen to music for hours without it rebooting, but as soon as I try to answer or even read a message my phone reboots...
So I thought it might be the ROM. I installed CyanogenMod and at first it was better. But after two days everything started again. I am really confused as to what is wrong and I can't find a proper answer online. Some say it's Android 4.3, others say it's the battery.
So I was hoping you guys could help me out.
Greetings,
Krytos.
Try flashing the stock Rom and see if the problem still happens

Just flashed the stock rom and it did not help. Issue is still present.
Which tells you it's a hardware prob = bacterie
Yeah, that's what I thought. Gladly I bought a battery like three days ago, so I hope that will fix my issues.
maybe hardware problem of battery or even board.
Try to lock boot loader if it is open.
