phone keeps resetting settings to default - Xperia Z2 Q&A, Help & Troubleshooting

Im having this Issue with my z2 where the phone randomly resets itself while in my pocket. I got the phone Last month and it's been great up till now. The first time it happened I thought I had left the phone unlocked and it reset however I have a pin code set up so that's almost impossible as you have to input this in before you can reset. Does any one know of this issue or a fix for it? I'm concerned the phone has a hardware fault, as I can't imagine it's anything else?
Sorry I'm a bit clueless with this stuff on the most part!
Many thanks

I had this happen to me with my Previous Z2 which was replaced with this one
I havent had it with this replacement
1. Try repairing Via Sony PC companion
Note your storage will be wiped so backup first
2. If it happens again, send to try getting a replacement or repair as this is a device fault from sony and should be covered under warrenty

[Solved] [help] having some problems with p500 after repair

Hi.
I just got my p500 that went to repair( i bricked the phone) and they fixed it and updated to 2.2.2 but im having some issues.
The phone doesn't turn off the screen, even tough its set'd up to and i have to lock it in order to turn off the screen and sometimes just turn back on even without a text or call and i have to again lock it. Other problem is that the phone does not recognize that it's connected to the pc by usb.
I already tried do a reset by restoring the factory settings but it didn't solve anything.
Does anyone know how to fix this? I didn't want to sent it back to repair because it took a long time for they to fix it.
Thanks
All p500 tht was repaired by service hav this prob, I think its due to faulty motherboarf tht they using.
So that means that i will have to send it back =/ Theres really nothing i can do? I even thought it was all software related and if i flash the phone with the 2.2.2 room (im afraid that downgrading the room will brick the phone) but i don't know if this is possible to do with 2.2.2 and because i haven't found how to root this version.
I had the same problem too after get back my O1 from warranty, really feel disappointed with the service.
Anybody can help except sending back to that stupid service centre ?
Did yours took too long to? Mine took almost a month to get back from repair and it came with all this problems.
Im disapointed with the service too.
You should hav been careful in the first place.
Its a dead end now.
I don't see how its a dead end now.
I should have been careful at the first time while was trying different rooms with different methods and that's why the phone died. I sent it to repair and they replaced the motherboard from what i understood. So if it a new motherboard and i havent change anything since and im having these problems i don't see it as a dead end but as a responsibility from lg or the company that repaired the phone and my provider to repair ir. So maybe the first time since it was my fault it would be my responsibility , but they didn't question that and i didn't say anything. After they repair it but with a malfunctioning piece it's their responsibility to fix it. At least that is how i see it.
Im going to have to sent it back to warranty to repair and i hope it doesn't come with the same problems again.
Ok its not a dead end oO''
I understand ur rage... But I jst warning other users to take precautions while messing with the phone. Or they wud also qq over a bricked box..
Gudluck with the service..
Cheers.
Thanks.
I subscribe your adivce.
I have been thinking of reinstall the firmware(the original from lg) to see if it solves the problem, but im having a issue. I can't connect the phone to the computer(only transferring things to the sd card and install or open from there) and i don't know if i can root it with this version i have now, 2.2.2.
Does anyone know how can i do this with the android version and without connecting it to the pc?
PROBLEM SOLVED
I was planing on sending the phone to repair on monday, but at the time and with the phone here i didn't want to give up so i thought of rooting it and reinstalling the firmware, but nothing worked and the phone didn't recognize that it was connected to a computer. So i kept search other ways to reinstall the firmware and came across a website that talked about a "secret menu" code for the phones and i remembered that this phones must had one and that from there i could do something, i did. From there i did a factory reset and, unlike the ones i did before by going to settings-privacy, when the phone rebooted it told me right way that it was connected to the computer. I also tested the problem with the screen light and so far, so good.
So, if anyone else has this problem(sannielyk reportedly had) what i did was entering the "secret menu" code : 3845#*500# and did the factory reset from there.
Apparently it was a software problem or something that wasn't installed right by the lg service. But so far everything is good, and i hope it keeps that away.
Thanks for the help
Edit the title as [solved].
Goodjob bro.
Cheers.
Done.
Thanks
Thx a lot to griffin_1.
I tried ur "secret menu code" to reset the phone & it is really work , now problem solved.
No need to waste time back to the lg centre.
You're welcome. Glad i could help and that sending the phone to lg could be avoided in this situation.
Oh man you saved my life. I don't know how to thank you. Thanks, thanks, thanks a lot, it really worked.
Thanks griffin_1.
I had the same problem and i was going to send it back to LG service. but ive fixed it with the secret code . Thanks again.
hey people i did send my lg p500 to repair becouse something went wrong the change my mainboard and the ime well done , then i got the 2.2.1 as stock rom
good then i did upgrade to Noijins megatron then the problem starts sometimes
if i just use power amp and want to go to the facebook app the phone simply start blinking the buttons like u would overclock your phone.
then it just reboot from alone i think i got the problem 4 or 5 times a day and i simply start beliving that maybe the gprs or the module might be done for the internet.
so i think should i send it to the repair again ? i even try to flash my baseband
same error at the new roms.
i hope you can help me griffin
got the same trouble like u since lg change my motherboard.

[Q] Stock S III boot loop - SIM?

My stock, never-rooted GT-I9300 (4.1.2, I9300BWELK1, JZO54K.I9300XXEMC2) is plagued by boot loop problems. It first started about 3 months ago, where the blue charge LED would suddenly come on and the phone would not wake from sleep. I pulled the battery, then when it was turned on it showed the initial S III logo, then the O2 logo followed by the glowing Samsung logo. Then repeated from the O2 logo endlessly. I pulled the battery again, then the next morning restarted it without the SIM or SD card in, and it had done a partial factory reset - i.e. lots of phone contacts were there with the texts, but all the settings had reverted to default. Later that day while on charge the same thing happened again, and I sent it away to O2 for repair.
When it returned, the same thing happened 6 weeks later although this time it was on when it froze and went straight to the O2/blue LED stage. Another repair (I'm fairly sure these 'repairs' were just factory resets...), and 6 weeks later exactly the same. Back to the O2 shop for another repair.
This time they replaced the 'main board' and when it came back it had a different Wi-Fi MAC address. This time only 6 days elapsed before the same fault arose again, and finally I was eligible for a replacement handset. This lasted 2 days before a boot loop condition occurred again! This time, being sure it couldn't be a hardware fault I tried my own /data and /cache wipe, which worked. I skipped all but the must-have apps, and I thought this was going to be stable but once more this past weekend the boot loop happened again (I've got my restoration procedure down to about 15 minutes thanks to the practice!)
I don't know what could be causing this and I'm fed up with resetting my phone. Are all S IIIs this unstable? I've never had a phone that required a factory reset within 18 months! When it is in the boot loop, I can access recovery and download modes, but safe-mode start-up has no effect.
The last remaining candidates I can think of are a problem with my SIM card, or a defect with my SD card... or an app. Can anyone suggest the best way to troubleshoot this? I'd really really rather not have to skip importing my settings as I have among other things many SSIDs I don't easily have access to re-create.
What ROM are you on? 4.1.2?

No, not all S3 owners experience this, a factory reset solves most of these issues however, if it doesn't, a trip to the Samsung service center will help.
I'd say it's probably a dodgy app, or some kind of unstable firmware update for your region/carrier, since hardware replacements didn't help with it.

Hmm. Thanks for the reply. I'm not sure I know anyone else with and S III on O2-UK but it seems to be news to O2, so I assumed it must be fairly rare.
I'm not sure about dodgy apps; testing them one app at a time isn't really feasible as it can take up to 6 or 7 weeks to fail judging by past performance. Are there any logs or similar that I can pull out somehow in the event of a boot loop? I've seen about logcats but I am not sure if this would be of use

Everything to carries is "news".
I can't help with logs and whatnot, so I'll leave that to someone else.
You can always flash and downgrade to the older firmware that didn't give you a problem, if the problem persists, it is indeed an app.
Even when rooted, informative logs are nigh on impossible to get

Thanks again for the replies. I'm not wild about downgrading. I liked the improvements! Is it possible to downgrade in a carrier supported way? Retaining warranty compliant has been rather useful in the past few months!

Well late Friday night it did it again. Not sure when exactly as I was asleep. Woke up in the middle of the night and went to check the time, Looked at my phone to find the blue LED on when it should have been red for charging or green for fully charged, and it was very hot - wouldn't turn on either. Pulled the battery but it kust went into the loop. I was away from home so I couldn't do any troubleshooting and had no choice but to wipe.
This time I didn't restore settings and the only apps I installed were SMS Backup & Restore and Puzzle Alarm (I know this isn't the culprit as I only started using it this week!). Gone are all my precious wifi SSIDs but otherwise I'm not sure I've noticed the difference.
So I'm now not connected to my work wifi, nor have I set up my work email or Lync - two of the things I use my phone for must after Facebook which I've also not reinstalled. Facebook mobile web is really hard to use by comparison.
By chance I popped into the O2 shop later that day and had the fortune to bump into a Samsung rep who had never heard of this and agreed that I was unfortunate to have these problems (how touching!) and suggested I speak directly to Samsung support rather than O2 which I will do this week. I will also contact O2 about a replacement SIM and look into replacing the SD too.
This is really silly. I'm not keen on downgrading the software because the first thing either Samsung or O2 will do is upgrade it again. Frankly at this point I'm fed up with the whole thing but I've got a year left on the contract and even a pretty much new handset like mine won't fetch enough.

Z2 rebooting automatically

Hey guys I'm new to the forum so go easy on my
So here's the story, last month when the .314 update came I was to impatient to wait until it got the over the air update so I dowloaded it from XDA flashed it using flash tools. I've done the many times before tomy z2 and also to my previous phones and everything went fine. But this time after around 20% of the flashing was complete the completion bar just got stuck there forever. I waited an hour but nothing seemed to be happening so knowing well that it'll brick my phone I unplugged it from the PC. After some googling I found out that there was a new version of flashtools available so I unisntalled my previous version and installed the new one and flashed the same ftf file again. This time to my relief the flashing went normal and my phone was successpfully updated. After a few hours of use my phone just randomly restarted. I didn't pay any attention to it but in the following days my phone started restarting at the most random times around 3-4 times a day. So obviously I knew that something has gone wrong. So I used my booted my phone into safe mode but the problem presisted, I tried doing a hard reset and then I use SUS to repair it but the problem was still there.I even flashed the singtel version of the same firmware version but even then the phone just randomly rebooted. There's nothing wrong with the sim because I switched the sim too (because some people kept insisting that the sim is to blame although I knew in my case that it wasn't) but as I expected the problem presisted. Now I'm at a loss as to what to do.I bought the phone from singapore but right now I don't live there so I can't claim warranty (even if I could).
So I turn to you, the experts in XDA it would be great help if you guys can guid me to a solution or atlesat tell me what the hell is actually wrong with the phone.
Ps: the restarts are entirely random. eg: I can play asphault for hours or shoot 4K for a long time without any problems but then I try texting someone and the phone restarts.

Telephony is actualy the phone part of a smart phone, its sim card slot to the app it self
Usualy when there is a problem with any one of those it will cause a phone to not function properly
In this case yours is one of them
Replacement or repair is needed ;D

I see. Unfortunately the country I live I'm in at the moment doesn't have a sony service centre or anything of the sort so I have to go back to Singapore to actually give it for repairs.
But how is it possible that I got a hardware damage just by a flashing error? I mean before that incident the phone worked just fine for 3 months and I've never dropped my phone or done anything to actually damage it physically.

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.
Sent from my E5823 using XDA Free mobile app
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.

Z2 shut itself down every 2 hours

Hello all, I'm really sorry if this issue mentioned before..
Well I have a Z2 , updated it from KitKat to lollipop to marshmallow, all good and great, never had any issues..
I had to sell the device cause I live in Syria and really short of money, so I did a factory reset, and sold it..
The buyer now telling me that device turns itself off ,while not using it, every 2 hours, he gets it back on without a charger, and find same battery, he's telling me battery life is great and normal no issues..
He did a factory reset, and he said he repaired the software via Sony application on PC. Still same issue..
Only activity he did, was getting his Facebook and some apps from Xperia T2 to the Z2 through Sony Application on PC, but he deleted them later, and still same issue, according to him...
Any ideas or suggestions about this please???
Thanks in advance.

But how it never happened before!
Only when the buyer bought it!
Why you think so? And any solution?

happened to me once the phone automatically shuts down it self at sharp 2 am i flashed a new ftf using flash tool it was all good it happened because of kernal auditor i believe. tell your buyer to run the phone in safe mode and use it and check if it shuts down again. if it shuts down again it might be a motherboard issue.
