xperia z ultra software very unstable - Sony Xperia Z Ultra

my Sony xperia z ultra goes berserk and haywire quite often........I guess the software is quite unstable ... Sometimes after opening the home page the phone strangely starts operating on its own.. The pages gets changing, sometimes the contacts gets clicked, phone calls get activated...once my phone was lying ideal and after i got a missed phone the phone automaticaly started went on a dial mode dialing the phone number from my call logs
Today suddenly the wifi got activated, the home page got rotating and kept changing....I mean the phone is lying in front of me and i am not even touching the phone and everything is happening on its own the phone going berserk......
Help .. has anybody else going through this same problem........
Today while i was browsing the twitter ...suddenly my twitter went overactive ...automatically getting clicked on send tweet tab and sending blank tweets....
Godd..........is it a ghostttttttttttt.... i am lost and pulling my hair.. never seen a phone behave like this in my 20 years of having a moble phone with me...

Note: If you initiate this process, you will lose all the data stored in your phone’s memory. All settings within the apps will be lost. You will only retain the data on your card; like your music, photos and videos.
1. From your Home screen, select ‘Apps’
2. Select ‘Settings’
3. Tap ‘Backup & Reset’
4. Now, hit ‘Factory Data Reset’
5. Tap ‘Reset Phone’
6. Then hit ‘Erase Everything’
Once this process is completed, your Sony Xperia Z Ultra will reboot itself. That’s it, most smartphones abnormities are solved by simply performing a hard rest.

Model?
Firmware build please?
-Latest is 14.1.B.1.526. (if your is lower, update it)
-Download Sony update service
-Follow instruction.

its firmware ending with 510 .. no we havent got the new update of 526 in our country.... as jutley said will try doing a hard reset.. hope it works..

Even with the latest firm the phone its far away from the stability in the 475 firm. In my case it must be with the backlight optimization on if not acts funny (not only for the booting...)

Dirty screen? have it if i touch my screen with water on my hands or flour. It stick to the protection and do like if I was touching the screen again and again until I clean it ^^

If I have to pick which Z Ultra C6802 firmware is the most stable, I will definitely go for the .475 firmware, without any doubt.
In all honesty, with the latest firmware updates, it feels more like a downgrade to me. With Optimised backlight always on, the colors of the display looks dull & faded.
If you untick Optimised backlight & restart your phone, then it will go haywire to the point that you wish you've never purchase it in the first place.
Sony has taken a step forward & 2 steps back with their latest firmware updates - Tell me What's the point of rolling out enhancements & new updates, at the expense of firmware stability?

There must be dirt or water in the screen due to sweaty hands on you r screen causing this. I had the same pribelm. Lock the phone and wipe the screen with a neat cloth or paper. It will be gone.

unstable xperia z ultra software
Tried everything damn thing you all guys asked me do.. even resetting it twice... nothing seems to work...... finally called the sony service center guys... well they admitted its a software issue and needs to be updated and quite strangely its a an update which they claim can be done only in the serivce center and not in my home thru pc companion nor over the air thru from my mobile....
Its sound quite strange to me and hearing for the first time about a software update which sony service center provides exclusively provides and which is no available to the end user..
Anyways i am quite exacerbated by the whole thing and finally decided to go back to my note 2 which i have still retained..
Sorry Xperia guys ...do u have think i have made a mistake by changing over to z ultra from note 2 .. or its a just a one of thing.... which should get settled by this sony service center upgrade...
sending it tomorrow, will keep you guys posted.........if it doesnt work even after this i guess i need to pop of my xperia

My guess is that they simply reflash the ROM. There is a new update out today BTW. Have you tried it?

xperia z ultra updated to firmware ending 532
my mobile just got returned from service center with the new firmware installed.... now to see if the bugs have dissappeared..
never imagined sony can release just a major high end phone with so much of bugs in it.

This is your bad luck. I never had any problems with Zu, now I,m on third firmware, I have changed the country code, rooted etc. And never had any problems with the phone. Maybe your problem is deeper than o simple firmware install, that is why they asked to send the phone to service. I guess it's just bad luck

Because it's already perfect.
Nah, i don't know. Maybe the updates are location based, i.e the models that got sold in Asia have some problems, and Sony is trying to fix them, and the "western" versions are from a newer batch and don't have these problems. Maybe Sony noticed something funky from the first batch, but then it was too late, so they went like "**** **** ****! Execute them updates!", and meanwhile in peaceful Europe - nothing. We got the good ones.
This is of course completely wrong and i have no idea what i'm talking about, but it could be. Could. But i doubt it. Yes. I doubt it. I'll stop now. Soon. OK, now.

usually, Restore factory setting can solve it

Hi..my hp start crazy justnow..so try with reset with secret orange button (inside sim slot) with needle or pin.
Press along 5 second..till or hp was shutdown. Now my phone coming back to normal...

Xperia mini pro sk17i reboot loops

Hi,
I bought a mini pro sk17i a week back. I updated the phone via pc companion to 2.3.4 (4.0.2.A.0.58). The phone was working fine, but after 2 days it started to reboot itself after a call. after 5 continuous reboot i reset the phone (erased all data), then it worked fine for 2 days. Today while i was shopping i made a call, then it started to reboot. One of the things i noticed was from that point any number i dialed was not showing in the call logs. i couldnt reset the data as i was busy shopping and kept the phone in ma pocket. Later i find the phone is switched off mode. I tried pressing power button but nothing happens. Took the battery out and re inserted the battery. did a reset and it started to work fine. When i took the battery out it was a lil hot (warm) and the phone was also warm (battery area).
Here are my questions;
1.Why did this happen.
2. The phone was a lil hot when i removed the battery, can any part inside the phone be damaged if it goes hot.
3. Is this because of hardware problem/Software problem.
(I did a full reflash using flashtool and the latest firmware, till now its working fine.. dunno if this will happen again)
seems like firmware problem to me.
take the phone to service center if haplens again.
but I guess its fixed now, tho I dont know the reason, might be something happened by updating
It happened again. I flashed back to 4.0.2.A.0.42. What could be the problem.

This might be due to any software you installing after flashing...
Try to remember what you do after flashing and uninstall that software
Else get global copy of .58 update and flash that .ftf packageby using flashtool...

Have you had this issue since flashing back to .42?
We will roll out a new software starting next week (.6x) mainly meant to improve the memory management to avoid reboots. Might be exactly what you need.
The roll out will start 12W02 but all phones won't get it at the same time so I cannot say for sure when your phone will get it.
Please post again and let me know when you got this so I know if it helped or not.

Hi Markus, Thanks for the response. As soon as i bought the phone i updated the firmware using pc companion. The flashing part went fine and the phone was working fine for 3 days, then it started reboots and turnoffs. I reinstalled the firmware and the same happened again. Then i observed this repeatedly happens when i finish call or lock the phone once it happens. i Also noticed the last called persons info is not stored in call log. But if u plug it for charging then the phone is fine. I rolled back to the previous .42 version. It was working fine for 4 days, yesterday after an hour of music playback (battery was around 44% or below) this happened again. i turned off the phone once it started restarting itself . then turned it on and cleaned the call logs. From that point its working fine without any shutdowns/restarts. Please help, i'm pretty sure that this is not a hardware issue. if the phone can run fine for 3 days without any probs..

me too when i use GPS or Wlan (.42 and .58 Firmware).
Thanks for the info.
I suggest you wait for the new update (.6x) which should hopefully be available for your phone very soon. If this won't fix the problem you have or if you don't feel like waiting for it (I cannot give an exact date when you will get it) you should contact a service center and have them examine the phone and do whatever necessary to get it working properly.
Repair routines varies a lot depending on market and local laws so you should give the local support a call and ask for some info about this if you choose to go with the service option.

[Q] Lower Buttons gone Haywire on Sony S Tablet

Hi! Im finally bringing this up to the general community after a month of suffering from this thing my Sony S Tablet is experiencing through. My Sony S Tablet randomly touches itself on the screen, to be more specific the lower function buttons ( Back key, Home Key, and Recently used app Key). Its really annoying when im browsing the net either stock browser/dolphin HD or watch videos on Gallery/Quickpic the tab touches the back button or home button and repeatedly does that and wont stop until i lock the tab or even turns it off. Its getting more worst as each day passes by. I think i noticed this one after doing this one:
stifilz said:
Then you are very, very, very, very lucky. LOL One of the only regions left that we can root (as Sony removed 3.2.1 from servers when 4.0.3 ICS R1A/R2A came out.
You are on 11000 version so flash this:
0035
http://www.mediafire.com/?cti11ejoxpxx4cm
This will give you 3.2 (newer than 11000) kernel 10 (don't worry about the k10 issue, not relevant with 3.2)
Then flash this:
0042 (under kernel 10 3.2.1 : ) )

There are the files to install:
Move to SD card (not possible without SD)
Insert SD card
Turn off tab
Hold VOL DOWN BUTTON
Turn on tab, while still holding VOL DOWN
TAHDAH recovery menu. Flash as above
NB vol up, down are up, down and use power to select, install update from SD card, choose update from zip.

When i first recieved this one all was well. but only when i tried rooting/upgrading it for the first time and it became worst when i successfully upgraded from HC to ICS 4.0.3 RC5
I tried:
1. Factory reset via Recovery Mode
2. Factory reset via settings
3. Erasing everything on the external storage
4. Changing into "Medium" the touch and hold delay
but still the problem persists. Anyone got any clue regarding whats happening on my Sony S Tablet? I also got queries
1. Could this be a problem with virus? i tried clearing up the external storage but its still there
2. How could i revert back to the original ROM i was in when i first recieved it? i dont care if its HC as long as the annoying problem disappears
3. What if i lost my Original receipt of my Tab could i still avail its warranty if i finally decided to send it back to the service team?
4. And is there any cure to this madness my tab is into?
5. Anyone knows whats the specific name my tablet is experiencing? Google cant be my bestfriend if i wont give him specific items to be searched
Any forms of help, suggestions and advices are warmly appreciated. Thanks!
Do you have a screen protector installed? Had the same problem about one week after installing the protector. The problem disappeared after some air escaped after rubbing the screen protector. Looks like there was some sort of static interference with the touch screen. Haven't had this problem again since. Good luck!

Probably from Heating
Touch screen recognizes touch from heating. I had the same problem too, and here is what I noticed:
when the battery level goes to ~<20%, the problem starts. charged it to full, and it was gone. checked 2 times. Doesn't cause problem when fully charged.
when the battery level goes down, the tablet slightly overheats at the bottom. I think that is what causing it. Try charging it to full and report it here if the problem still persists
Have that issue also. Don't think it's too common actually. The reps. at my local Sony Center just laughed at me, and said they never heard such thing before.. Never noticed if it's battery related, but will look for it, next time it occurs. That'll mean it's a hardware defect that can't be solved without changing to a new unit.. =(
Batery is probably at the same location.
If thats the case i be worried, sony has bad reputation when it comes to batery's if they become hot verry rapidly they can explode.
Sony vaio team is the one that made this tablet and the xperia tablet s.
my batery is in top near camera can become warm, i defiantly put my tablet upside down next time it becomes warm to see if i can re produce this, if thats the case others probably have same issue also.
http://news.softpedia.com/news/Sony-Exploding-Batteries-Chronicles-37848.shtml
I have the Same Problem. I can't use it anymore.
Still waiting A Response from sony support.
Any clue how To Solve this?
Even with full batery, the tablet is crazy.
-bump- the problem returned... anyone else experiences the same thing?
Still present after JB update. This time though, it is more aggressive than before.. :S
Sent from my Xperia Z
anyone tried sending it back to sony or has found some answers to this annoying presses?
I have had Mine to service at Sony Center twice. They replaced The mainboard both times and The screen The second time. Definately not hardware related.. Will send it back a third time tomorrow and Ask for a refund. Will be cheaper for Sony, as the mainboard probably costs almost as much as The device it self..

You go search to internet and search for the previous OTA firmware of STS (Sony Tablet S)... for examples 4.0.3 Release 1a (signed-nbx03_001-ota-120803002).
- Download it (in zip file)
- put it into your sd card (in zip file)
- switch off your STS
- switch it back on while holding button 'ON' and Volume + button (hold together)
- Once the Sony logo appear, release the button 'ON' but not the volume +
- Once the blue screen appear with menus then release the volume + button
- Choose 'Update via sd card' ( scroll with volume - & select by pushing 'ON' button )
- Once choose then wait until it reboot.
- tadaaaa...finish...you are now downgrade from 4.0.3 Release 5a...and the screen touch by itself will no longer appear.
pssst : STS will ask for update to 4.0.3 Release 5a..... i don't think you would since previously we having the issue.
Good day.

Xperia Z2 Black Screen

Hey Guys,
Just got my new Xperia Z2 2 days ago, the phone looks nice. Compared to the Samsung Galaxy phones I had before (S4 & Note 2), the Z2 feels like a real phone especially with the glass frame.
The phone is fast with a nice camera, the only comment about it is "too much bezel" which I think SONY could've done a better job by "trimming" the huge bezel....
Today I unlocked the bootloader and was about to root the phone when all of a sudden the screen went black with no light at all
Tried to reset the phone, reboot....etc. nothing really worked, I did some search and found out that this is a common issue with the Xperia Z & Z1 as well and looks like Z2 is having the same issue..
Just had to take the phone back to the SONY store, they didn't have a replacement and they told me that If I needed a replacement, that'd be back order and I'd have to wait another month !!!
Also, they were hesitant about returning the phone and told me if I used it for over 30 min., then they can't return it and they'd have to sent it for repair....luckily I had used only 25 min. !!!
Just be aware of the issue. Also, does anyone know if the black screen issue is very common on the Xperia ?? I liked the phone and was thinking about buying another one.

hmmm, if i was you i would use the phone as it is and wait for some couple of months before rooting it since it is new on the market and issues will keep on going till bugs are sorted out and that rooting should be updated with new files and then after users review i think then you might just root it but for now there's too much bug even with its stock firmware its normal wait a bit Disable all apps that you don't use for now
Screen of death
I had a similar situation with my new Z2 although nothing to do with the bootloader, rooting the phone etc.
Basically screen went blank after using a magnetic charge adaptor. Anyways depends what country youre in/phone provider.
I got my phone via a plan and was well over 30 mins of use. My phone lasted about 1.5 weeks and my provider have a 30 day exchange policy if a fault is present.
My phone wouldn’t respond regardless of the power button and volume buttons same time. when on charge I got a flashing red light, not the constant orange charge light.
Anyways went to a shop and got a replacement on the spot.
I don’t know if its common with a Z2 as they are just too new yet. Overall im very happy with mine and suspect I just got a faulty phone, it happens.
Same here buddy! I tried the top three, xperia included. Xperia is good and I have no complaints.
Obsessed with rooting and romming since the android SGS years, I bought an Xperia Z2 also to stop my obsession lol!
After 15-AUG, I may root, if a root is available on locked bootloader. Lets wait for DoomLord to attack on the stock first.
Thanks guys,
Well, I don't consider any android phone to be really a phone without rooting...
BTW, Does anyone know a way to run rooted apps on non-rooted phones ??
Thanks again.... :good:
you cant run rooted apps without root :/
unless you mean something else

Random reboots

Yet another problem with my device: random reboots. No matter what I'm doing, lots of apps open or only one, battery high or low: the screen goes black, the red LED blinks a few times and off the device goes. Any other people experiencing the same?
You most certainly have a faulty unit.
It happened once. I got the phone on Tuesday. I was reading on Flipboard. Let's see how it goes.
Sent from my E5823 using XDA Free mobile app
it happened to me too, it was within 7 days period so i exchanged it for another one, the new one has been problem free
one of my friend also had random rebooting problem on her z3c and she sent it in twice for repair without success, if i didn't hear her case i wouldn't have demanded an exchange
Happened to me too, listening to music with my headphones, I pause the music to talk to someone, 5 minutes later press the headphones button to play, nothing happens and when I check the phone it was rebooting. Hasn't happened again yet, was 7 days ago
My phone has rebooted maybe 5 times in two weeks. Usually phone has been idling on table.

Seeing all responses here, it doesn't look very promising... I dont want to send it back yet, because the "service and repair" here in NL is a joke. They do a factory reset, say everything is fixed and send it back to you. I've experienced this before several times with my Z3c...
Hope a sofware update gets rid of these blackouts and bugs.
I got zero reboots after 1 week so i wanted to let you know because its to easy to get negative things out while the people with no problems dont come to the web because they have no reason yet
I had this problem, I fixed it by flashing latest build from xperifirm, and
I also had noticed media storage app using 1gb of memory so I forced close n cleared data and problem has gone.

that's exactly what they did for my friend's z3c, they kept believing it was a simple software problem, you gotta be tough to get more
like the other guy said, my first z5c would reboot just sitting on the table doing nothing, i suspect this might be more than software
Ill repeat, mine does not reboot for itself, and if would be, its an obvious sign 1) you did something what the device doesnt like, 2) you clearly have a faulty unit. Peace of cake, nothing to worry about, just exchange it and voila.
I've been having this problem on my brand new Z5 as well. I bought it from Clove so I really don't want to have to send it back. Gonna try and see if I can narrow down the cause or try to see how I could fix it (factory reset, reflashing the stock firmware or whatever).
Really hope it clears up.
Edit: So I repaired via PC Companion and I don't want to speak too soon but it looks like it's all good. The first time it happened was after installing a bunch of apps, including some older ones as well as some obscure ones. It's entirely possible that one of those apps were at fault. I've tried my hardest to replicate the issue since the repair (and being much more conservative with the apps that I've installed) and I haven't seen it happen once. I'm definitely hopeful now that it was an app-related issue and not a hardware one.

Just out of curiousity..
What color is your device and from where did you purchase it?
Ive been hearing about faulty white Z5Cs which Sony acknowledged even.
Mine is black. But I have only had one spontaneous reboot the second day after I bought it. 3 weeks now and it hasn't happened again.

Mine is black color.
I have it since 4 days, and it already rebooted three times randomly ...
I don't know if I'll keep this phone or resend back and have an other brand device.
It happened with my white one when I had my SD card plugged in. I sent it back and got a new one
Mine's black and it never rebooted on its own
Black Z5C. I've been getting that kind of reboot regardless of repairing via PC Companion, or build number.
Any thoughts on what might be the issue?
Also, off topic, I believe I have two dead pixels (installed Screen test, and two pixels can't reproduce blue color) and I was wondering if that was an issue that might get me a new phone or just repair (it's been 2 months since I got it)?
I've had it for a month and maybe have gotten one or two reboots. I recently took a week long vacation and got 4 or 5 freeze/reboots. I'd be viewing photos, taking a picture, recording 4k and it would freeze. Power button could still bring up the menu but screen is not responsive. Eventually it reboots with the red led flashing. Only one it just rebooted with no warning
I have between 0 to 3 restarts/day. Sometime it crashes and freezes in the crash without restart. That is very nasty. I'll try to track it down.

[SOLVED][Xperia M4 E2333] - Startup Logo bootloop or Android continous rebooting

Hi all,
after 3 days of searching, maybe I've found something sounds good, but I'll stay in test mode for a while and I'll keep you in touch in case it is really stable.
What's happend :
3 days ago I did a simple ''factory reset'' and since then I experience a continous reboots after a minute or two alive in Android official 6.0.1 and a bootloops when processor cames really hot.
At this time on internet you can find lots of people with the same issue and all of us without any solutions at all.
Now here the list of my tries :
- Did again a ''factory reset'' with Sony companion and Sony flashtool Emma : no changes
- Call Sony for support? Warranty still okay? : do not waste your time, Sony wants your money and thats it ! (take a try anyway, you will see by yourself)
- So let's root the phone! Even if you do not know what to do, you can find looots of Tutorials and lots of very geek competent guys to help you (better than Sony support anyway), thanks XDA Developers !!!
- Even if I've completely erased all partitions with TRWP, when flashing and back again in stock Android with xperifirm : still no changes !!!
Now, during those tries I've noticed that the temperature of processor is dangerously high, and that for every startup process.
You know, at the end I think that the bootloop (I guess in that case only) it is made by temperature mainboard automatic protection.
Anyway, before to play freesbee with and go to buy a new one, I've tried to :
- open the back side (very simple but all operations should made very carefully)
- unplugged the battery for 15 minutes
- take off processor's metal protection to avoid heat retention
- plugged the battery again
- close the back side and started Android
Since then the phone is still alive !!! Just working as it should...
I'm trying all I can do to stress it to see if any problems happend again, installing back all apps, using Root features to uninstall useless Google or Sony apps, restet the phone several times.
The processor still heat up every time you do something or restart, but I do not experiencing sudden rebooting or bootloops again at the moment.
As far as I'm concerned, I would say as well that it is a processor issue, but I'm not a scientist, so I guess this apply to different Xperia models and not only to M4 Aqua Dual.
DO NOT FORGET that this is not a real solution. I just did the only thing that you cannot normally do with that kind of phone : unplug the battery.
I hope I can give some good ideas to all of you, or maybe a good way to a solution .
Happy to share,
Flaximuss
More information please

So, I will explain what has happened.
I received a Warning Statin "Unfortunately, Hike as stopped" followed by "Unfortunately Google has stopped" "Unfortunately home has stopped"...
So I shut my phone off, which I used to do every time and restarted it.
My what happened next is something I haven't experienced before.
My Xperia, just displayed "SONY" logo and nothing else. I know to flash and I have done that many times before. So I was lethargic that I could easily bring my sony back to the world. but that didn't happen anyway :crying: :crying:
I read so many threads in XDA but none of them could have faced what I'm facing. Coz my Sony Xperia Aqua M4 will not vibrate so I couldn't able to differentiate Hard and Soft boot.
After waiting for a restless 24hours I tried to open my Sony Xperia Aqua M4 that's when the real problem started...
I found a video that if we remove the battery and reinsert it then everything will be fine.
so, I removed the back cover.
Flip opened that Copper Layer (I really don't know its purpose though) and unplugged 3 battery plugs. That when the things began to get out of my hand.
After reinserting the plug I started my mobile once again only to see the Sony Logo and not the blue waves. So I tried to restart the mobile by pressing the Rest button near the SD Card Slot only then I came to know it stopped working.
So once again I unplugged the battery and this time I had that copper layer trimmed and replugged the battery.
And this time no Sony Logo too :crying: but I could feel the temperature of metal on the board rising to its peak. I don't know what to do...
Is there a way to make my Sony work again?
Pieces of Advice Please.......
Temporal solution
If you don't want to disarm your phone I got one solution:
1) Press the screen with your thumb and the back panel with index finge, near the nfc logo
2) At the time of starting it helps sometimes.
It is an hardware problem.
The solution worked but...

Hi, the phone has started up, however, is there any way to make the solution last?
Please it would be really nice that there is a chance to recover the phone.

Of course there is a way to save your phone, but nowadays the process cost more than buying another M4 AQUA used. You can do "reballing" or a little "reflow" in any refurbishing store if you want but I recommend changing that phone. It is not so good to use mate.
