Xperia Z1C sudden crash and reboot - Xperia Z1 Compact Q&A, Help & Troubleshooting

Hello,
I want to mention that I didnt have any problems with my phone until 1 week ago. I just connected my phone to the charger right before I sleep, as usual, but I didnt notice that it rebooted the whole night. When I woke up I saw my phone with the time crashed and it was really hot. I turned it off for 2 hours but that of course didnt fix anything, so I tried to repair it through Xperia Companion. Then my phone seemed to be fine until a few hours later, it crashed and after a few minutes it rebooted. I didnt give up and I reset it to factory settings, but no difference at all. The phone keeps crashing and rebooting at random times (sometimes with an error message like " {this app} has stopped working", various apps but usually "Xperia Home"). What could cause this issue?

If it's persistent with a phone restore by PCCompanion, I would say some hardware failure. Are you rooted? You could maybe try with a different custom rom or something, and see what happens...

Thanks for replying, I'll try a custom rom. Do you have any good one to suggest?

If you don't care about camera, any of the newer N roms are very nice - https://forum.xda-developers.com/sony-xperia-z1-compact/general/z1c-nougat-roms-t3460868. If camera is an issue, you'll need to stay on LP. Try Jaguar or Cm12.

*UPDATE*
I searched a bit further about my issue and in the depth of my search I found someone that told that some clean type apps can cause this problem. I have Clean Master on my phone so I deleted it. From that time I havent experienced any crash or freeze or reboot. I still dont know the reason I had this app for 8 months without any problems, I dont understand what changed now.

I thought when you said you restored with PCCompanion that meant that it was happening with clean flash and no apps installed. Cleaner apps can often cause those types of problems, and it's questionable if they even help anything. If you must have one, I recommend SDMaid.

It didnt even cross my mind that it would be any difference to mention that I reinstalled all the apps I had because I never thought that such a "usefull" app could do that damage to a phone. Im glad its fixed .

Same problem. Connected my phone to charger, wake up next morning and saw that data disabled that pops up every time phone boots, but i didn't bother and just swiped it. Later that day i kept on seeing those notifications but i didn't bother as always until my phone just froze while i was using it. I could lock it but screen just went black and same image stayed there when i unlocked it. I had to restart it with that force button under sim cover. Problem was still there after reboot so i did factory reset and it was good for few days (more like 1 day) but it happened again. So i did system reinstall with pccompanion and it worked until for a week maybe and i thought i fixed it until few hours ago when it happened again. Phone was hot whenever that happened and crash.monitor keeps crashing ironically (i think that's the cause.) I never had any cleaning apps (i had clean master app lock for locking my apps tho)

oh my god... this is exactly the same Problem and I've been having it also for about the same time. It happened first on the night from Wed, 21st to Thur 22nd. When I woke up I only saw this screen which says, thats its restoring Apps (E.g. "Restoring apps 70 out of 200" and ongoing) Happens sometimes when it crashed - which was rare - so I didn't bother too much with it, but it kept freezing suddenly and randomly at any kind of app and screen went black, only thing I could still do was long press Power button, but sometimes it wouldnt even recognize the touch e.g. to select reboot. After a while in that state it soft rebooted itself. I also force rebooted it a few times with Power + Volume Up Key.
Also tried everything, like factory reset, Software repair through Xperia Companion, then switched SD-Card, an even replaced the battery because I didn't know what else it could be. This got me so far, that I was considering flashing a different Rom and just f*** it. Now I happen to find this thread by looking through the Xperia Forum - I didn't find it through Google... That's kinda sad, I might've not opened my phone if that App is srsly at fault... but oh well. I am just as surprised as you: I thought it could be an app but had everything up to date. And tbh.. I didn't even bother with this Clean Master. I installed it 3 years ago and used it a few times.. and kinda forgot about it, so it didn't come to my mind at all that this could be the problem. I'll uninstall it now and report back if it's solved for me, too.

Can you go to diagnostics and see application incidents. If you see only crash monitor tell me. That's where problem lies most likely

In diagnostics in "start" tab i can see everything. It says 19 systems incidents, 96 application not responding and 75 Application incidents. All of this was from yesterday and earlier. Hadnt had a crash today but I'll see how it goes from now on. What do you mean by "see only crash monitor"? You mean if you didn't accept sony to collect the crash data?
You also wrote, you were using Clean Master, did you uninstall it and did this fix the issue for you, too?

In system accidents there should be only com.sonyericsson.crashmonitor.
I said i was using Clean Master AppLock not antivirus. It's just app that can lock other apps with pin so nobody can acces it without pin.
Also you can check out this where we discuss about same problem

umm in system incidents it only shows a time and date whenever a crash happened. If you mean App incidents instead: I think I understand what you're getting at. As in: If theres another app in the incidents, this is the culprit. Well, as I said it happened very randomly before you can't pin it down on a certain app. Whatever I was using crashed and gave a crash report but most incidents were with "system-ui" Anyways, had no crash since uninstall of Clean Master. So I'm good for now.
When did I mention antivirus? Im referring to this:

So Clean Master, even if you only use it to Pin Lock your apps, might be the problem. Do you still have this problem anyway? Seems like yes, since you're considering to flash a custom Rom.

You don't need phone to be turned on to use xperia companion and flashing new software. Just open it click on repair software and follow instructions. After that just dont install official facebook app since thats most likley cause of crashing. Install some 3rd party client like simple pro. I use that one its awesome

[PROBLEM] Random freezes/crashes on Desire

Hey,
I know theres a lot of threads about htc/android phones freezing and crashing/rebooting but none of them really described my exact situation. And since it's getting worse and worse and driving me crazy, I wanted to ask for help.
As the title suggests my HTC Desire keeps freezing and crashing (sometimes rebooting, too).
It all probably started shortly before I first rooted my device, following the great sticky noob-tutorial. First problem was, that sometimes my phone wouldn't wake up from standby, especially after I a missed call (rooting didn't solve that problem).
Some time later, now rooted and with a custom ROM, I noticed, that sometimes when I wanted to use my phone, it showed the PIN-screen, which obviously means, that it rebooted quietly (don't remember if this also happened before rooting).
A few days ago it started to completely freeze, when connected to the charger. Orange LED showed it was charging but no reaction to pressing any buttons or disconnect the charger.
Since yesterday it also crashes randomly in standby mode (can't wake it up) or e.g. when watching a video (just freezes the device, no reaction to button-pressing, screen stays on etc.)
now I am running the stability test with the charger connected - no problem for 1h10min til now...
The ROM I am running is the latest cool sense (problems also existed before the latest update)
No modification of CPU (I used to use SetCPU but since I thought that would cause the problems I uninstalled it -> no improvement)
What could be the problem here? (And how can I solve it, of course?)
Anything else than a full wipe, which could help? (that would be my last option...)
Thanks for helping...
it just happened again -.-
I was just backing up some apps with titanium backup and in the middle of scrolling through the list - freeze!
dunno what to do...
is this hardware or software related?...
Hello.
It would be pretty easy if it is a soft problem. This kind of problems are usually dealt with by installing another ROM and see if the problems persist. So if you want to try and eliminate the last option, go and install another ROM, it can be a Stock ROOT-ed ROM, Sense or anything.
The fact that you mentioned your phone was crashing even before rooting got me thinking it is a motherboard fault. I've read some threads in which people had the same problems, and in the end they all got to the same conclusion: motherboard fault. The only resolve with this is to get it to guarantee.
So first of all try installing another ROM and if the problems persist, you will need to install a RUU and see if this one eliminates your problem. If not then I don't know if there is anything else you could do, besides getting it to the guarantee.
I wait for your progress.
Hi,
thanks for your reply.
The funny thing is, that I didnt have those problems with this ROM in the beginning. Everything was fine, that's why I was using it the whole time. But as I said before, it became worse by and by... thats why I thought it could be an app or so...
that would be a recent list of apps: appbrain.com/user/marioiram/
Cannot even sync my newest list, because after freezing while watching a video, it froze again shortly after reboot... still getting worse
Try reinstalling the ROM or installing another ROM.
hm.. just when I was thinking about following your advice, my desire stopped freezing xD
no crash, no freeze oder reboot since my last post.
I even tried to force it by watching videos, playing games, connect to the charger etc.
everything is fine... strange.
Will see for how long
Well this is good news. Just keep in mind what you can do if the rebooting comes back. Hope it doesn't
Well, it did xD
Now even shortly after reboot. I'll try ROM changes as soon as I get home but there's something I noticed: it often freezes when it's supposed to display a whatsapp notification and sometimes it seems there's a problem with the sdcard (just bought a new one because my old one went nuts). Sometimes the notification 'sdcard was removed unexpectedly' (translated from German) is appearing, but after waiting a few minutes everything is fine again...
Well I'll try some stuff when there's time...

Hi:
I just wanto to let you know that I had the same issue, so I decided to send it to SAT, they changed the motherboard...
my problem now (with the new motherboard) is everytime I root my phone and use a cooked ROM, then freezes/crash again... ONLY works with the official ROM...
please let me know if you solved you problem pls... and how? of course...

Random Reboots

Does anyone else suffer from random reboots with there device? it does it twice a day or more for me???
Is there anything i can do to stop this issue from happening again?
I.e wipe user data???
I've had it once or twice. Presumably a rogue app or a bug in the system.
I haven't suffered from a random reboot at all since having the phone on the second day of availability in the UK.
Then again, I haven't rooted mine, unlike others...
Yes I have had a few reboots in the few couple of days. Been ok since though

Not a single crash or random reboot so far. I rebooted last Friday after charging my battery and it's been running since without problems. My best guess is that culprit is one of your applications that you've installed, especially any application that tries to do something with Android and the device itself.

I had these reboots on a G2X and it drove me bonkers so I am always worried about phones doing it and I watch uptime like a hawk. Nexus has been rock solid since I turned it on the first time. No reboots. Sometimes it's apps and sometimes your use case just exposes a bug in the OS. Try doing a wipe and installing a few apps at a time so you can figure out what's causing it n
I had a couple within the first few days... nothing for a while...
This is just speculation, but I remembered seeing a thread somewhere in another form, in which a user with another device with the same random reboot problem was advised to check his sim card. A bad sim card may "vanish" for a while, causing the device to reboot. Again, just speculation, or if you wish, a hypothesis you can check.
I have something similar, the first time was when I was charging my phone, I woke up in the morning and I found my phone off and hot as hell. Battery pull and everything went perfect. then it happened to me 5 times, the phone freezes and turns itself off, then I have to do a battery pull! the last time was today I was listening to some music, then the music went weird, then the phone froze and turned itself off.
I called Three for a new phone as I have it for under 14days
It looks like there is an issue that google hopefully acknowledges like they did with nexus s.
I was listening to music on my way down the sidewalk thus morning and the mp3 started doing a loop of about 1 sec of the track over and over. Finally heard a pop and it went silent. Had to do a battery pull when I got on the subway.
Then on the subway about 10-20 seconds into a track after starting some music back up the track restarted. So I stopped playback thinking it may happen again.
I'll try to do what I can over the coming days to recreate this.

I would think that would cause more problems than that. I was listening to some tunes for a bit last night with no issue. And the issue this morning happened with two different tracks.
I had added a battery gauge widget to my home screen last night, I removed it just now. I'll try to recreate the problem from here without adding more apps or widgets. If I can successfully recreate it I'll try to hook up adb and get some logs.

I'm having random reboots too. I'm suspecting its something to do with either GO SMS or SlideIT. Do you guys have any of these installed too?

I'm getting another problem now. I've taken off GO SMS so I dont think its that. But when I get a notification (i.e SMS, email), I go to wake up my phone and the unlock screen appears. However it wont recognise any touches on the screen, then sometimes it will come back to life and other times it will reboot itself.
Never had a random reboot, I have go SMS installed.

Just had a random reboot with none of the aforementioned apps installed.
I was having random reboots when the phone was just sitting there with the screen off.
I had SetCPU under clocking when the screen was off, I removed SetCPU and my random reboots went away.

[Q]random reboots on my xperia play

Guys I've been having random reboot issues lately and i can't figured out what is actually happening. Sometimes it just reboots itself, randomly every time.
I thought flash another rom or kernel would solve the issue but it doesn't seems to work, any ideas?
I'm currently on DFR3.0.5 rom and DF kernel.
Are you overclocking and/or undervolting?
not really, i only overclock when i play certain games, otherwise i'll set it back to normal.
Is this question sounds stupid? It seems that nobody else would bother to reply it?
i have it some times like every 6weeks believe it or not its currently on stock, but that's made no difference had it happen on custom Rom's also and its allways at about 5 am just sitting there rebooting over and over. not sure if that's what you are getting?
it just sometimes rebooting itself, so i have no idea how and why
Try reflashing back to stock and don't change ANYTHING. Install your programs or whatever, but don't root it or any major system changes.
Use it for a while and see if it reboots. If it doesn't, you did something to it, overclocking/volting, and you need to figure it out.
If it keeps doing it, I hope it's under warrenty. But it also could be the battery.
Hardware isse
I have had 2 XP's and both returned as they randomly rebooted. When I called Dial-a-Phone(UK) to enquire they put me through to their support department. I had to do a factory reset, then install an update from Sony's website and try it out. Still did not work so they said it is a hardware issue. Fortunately I returned mine withing 28 days so got an instant replacement. Pity the second one did the same. I have returned that too and am awaiting my 3rd phone(what can I say, I love the phone). If this one does the same thing I will be moving though cannot be without a reliable phone at the moment(expecting baby) I hope you are covered by the warranty. Good luck.
Annoying as f*** I know mine are fairly rare they were more often when I was all stock two things that reduce it are an apkiller and everyday reboot

I reflashed my df rom and never overclock it.....(since i didn't play asphalt nowadays)....it seems like the probs has been fixed, or maybe not happening yet
Mines been rebooting randomly for the last three days now. In fact it just rebooted while I as reading this.
Sometimes tends to happen when I slide in or out the keyboard. It's breaking my heart as I love this phone :-(

If you have tried to repair the phone software via PC Companion and not installed any third party app's and it still reboots it needs to be checked at a repair center.
Contact your local support team for info about repair centers.

I have had the same problem, but my phone is only rebooting during games(especially HD games). Almost everytime I play Shadow Guardian HD, Backstab HD, or NBA Jam. I never have problems with FPSE and psx games. I am using DOOMkernel v. 11 and I OverClock to 1.14 or 1.21 max and 249 min when I am ready to start up my games. I am also using supercharger V.6 on 512 hp. Should I be overclocking at a higher voltage to stop reboots?
I started getting random reboots under .62. And hooking it up to logcat I was getting ANR errors from a ton of background 3rd party apps.
I think my issue was related to moving from Link2SD to App2SD. I forced all my apps to .android_secure and I think there was one app that didn't play nice. Anyhoo, restored back to .42 and my sd-ext and it works like it did.
3rd one going nuts!!!
An update to my previous posts. Received my third one late last week and have been really using it to make sure it does not randomly reboot. No problem there I am happy to say. The problem I had a day or so ago, is that when I was typing a text message fast, my screen went bonkers and started typing by itself. It then opened my phone app and selected a contact to call, it then opened and closed some apps and closed them. I pressed the home screen but nothing, so powered down and booted it up again. It just carried on going crazy so powered down again and took the battery out, the sim card and also the SD card too. This seems to have "fixed" it for now as I have not been able to replicate the problem. Anyone else had this issue?
FYI - I have been playing Asphalt 6 HD with absolutely no problems at all, as well as a couple of other games.
I think i just had a reboot yesterday night by itself...the reason i know it is the application will kinda er....reset it's position in drawers, some apps shortcuts disappears from my home and so on.....
just when i thought my problem has solved.........
I think it was batter

I also got this problem after changing with china battery. But when using an original battery it was ok. I buy extra for gaming. But now my original battery already missing. Hadoii...
To determine if your phone rebooted overnight, you can install "Android Terminal Emulator" from the Play Store and run the command "uptime", it tells you how much time has passed since the last boot
Or find an app that tells you that...

[Q] launcher crash every once n awhile

Hi, im running AndroidNow 6.1 and since i installed ot for the first time(version 3.2) my launcher crushes every once n awhile.
It happens with stock,google,nova or any other launcher - i prefer stock.
What happens really is, when i press home/back to exit an app to the homescreen,there pops the recent apps screen(with no open apps visible)and when i press home again to exit this screen , i see blank home page and then the icons refresh and everything reload. Latet when i open the app drawer i experience a little lag that the icons are reloaded also.
What seems to be the problem? Im rooted and ive got clean master but i dont think its related.
Please help me, thanks.
Am i the only one who experience this?
Happened to me few times. You are using 3rd party launcher?
Ps. You dont need clean master
i use the stock one,but it happned with all . why shouldn't i use it?
Tell me why you should?
This devices does not need that. It does more harm then use.
I love the feature that it prevents apps from starting on boot up.
Do you know how to solve my problem with the launcher crash?
I have the exact same problem.
This happened with the stock ROM and any launcher I tried.
Then I flashed a custom ROM (based on stock though), progressively reinstalled applications and after some time, the problem came again. Then, I progressively froze some applications with Titanium Backup, and now it happens much less than before (2-3 times a day against everytime I press "home").
My conclusion is that, even though that's a launcher crash we see, the fault probably comes from a background application. I'm still searching which one. Did you find something interesting since you opened the topic?

What I did recently was to :
- Disable the application "LIA Informant"
- Disable the application "LIA MrGDBLogger"
- Disable the application "LIA S4URecommender"
- Clear the cache (click on Settings > Storage > Data in cache)
The problem happened several times in a day before, but only occured a few times in weeks since I did this trick. The workaround was probably clearing the cache. But since the problem gradually came back after the last time I reinitialized the phone, I'm still afraid it comes back sooner or later.
I did clear cache a few times now - it always comes back.
Would be great if someone could find a fix for that, because it's very annoying.
The bad thing is that there is no send error report option. At least there would be a starting point with an error info etc.
Have you tried disabling the applications mentionned above?
I (almost) chose them randomly, but it really made a difference for me and the problem doesn't seem to come back.
Done that just now.
Will post back with the results in some time.
Do you maybe know what those apps do ? (I like to know what I'm turning off in case of any other problems)
GDB (in the Unix world) is a debugger. I have no reason to think that this GDB is the same though, I just guessed the problem should come from a system application and this one may be one.
Turning off those apps made no difference.
Was thinking that it may be one of the widgets on the home screen.
Later today, or maybe tomorrow I'll make a list of what I'm using and post it here - maybe this way we'll get whats causing this.
The only widgets I have now are Zooper Widget and Shuttle+.
But honestly, since the problem makes any launcher crash (and I think any application left in foreground when the screen turns off), I believe the root of the problem a system app/optimization, and likely one from LG since not many people seem to complain.
I hope 5.1.1 will come soon to the G3.
Any news on any update ? (not necessarily to 5.1.1)
Udated to 20p yesterday - clean update (just to be sure I've wiped 3 times - 1 before and 2 after the update).
Had a couple of hours of peace, and then it started again.

Question Random reboots

Well, I had the 6 Pro for about 36 hours. It kept rebooting randomly, even after a factory reset, so it's going back for an exchange.
Has anyone else had this issue?

No definately not, here the worst I have experienced is some app crashes, they probably aint android 12 ready, and some pretty big lag moments
I don't have any issues. Do you have the November update yet?
For some strange reason, I noticed exactly this aswell (one time, this morning). I was working out and my phone laid on the table, when I saw it lit up because it restarted for no reason.
I guess it's a software bug.
And no, there was no automatic system update - I checked, I'm still running the old version.

I tried to find one, but as of now I have been unsuccessful.
No, nothing at all either. Mine also installed silently at some point. I recall a notification asked for a reboot yesterday morning.
No, not had one random reboot since I got it on Tuesday.
Nothing here either. Good luck!

I don't have any issues. Do you have the November update yet?

I had the November update and all apps had been updated as well. It would freeze and then reboot.
I did a factory reset and did not restore any of my apps, just ran it with the factory apps, and it still did it. Since no one else is having the issue, I'm feeling confident it was a bad unit. I had the 128 gb version.
It's back to the pixel 5 for another week or so. I had to exchange that after I got it too because of a bad proximity sensor. Either I just have really bad luck or Google needs to tweak their quality control department.
Weird unexplainable OS crashes like that are usually due to faulty hardware, potentially RAM
If you're having issues, do yourself a favor and keep an itemized list (on your device, word doc on pc, somewhere) and notate the following for each occurrence:
-date / time
-the fault (self reboot, major lag, over heated, fast battery discharge, etc.)
-what you had to do to clear it (rebooted, closed app, powered off/on, etc.)
When talking with Google about a replacement, having THIS information ready to read off will make it extremely hard from them to give you any grief about you needing a warranty replacement.
An itemized list of faults is MUCH better evidence that you need a replacement than "well, it rebooted a few times last month"

I am inclined to agree here, but my years of working with Windows and Android incl. rooting and using custom roms and kernels want to disagree here. There can be half a gazillion software based reasons for an OS crash, especially with a buggy release like Android 12. Not sure if you participated the beta, but it reminded me of Windows 11. There was a buggy beta build with about 100 bugs, they fixed 20, called it a day and released it. Now we new P6 owners can play beta testers Volume 2 for Google.
One very important thing here is also: Did you guys set up your phone "clean" or did you copy over your old phone by cable or did you use backup?
Any of these things can cause issues.
I, for example, used a cable to transfer all file and apps from my P4 XL to my P6 Pro. It's possible that this is the rootcause for some issues, or maybe it's not. Maybe there are even problems that occur only if you transfer your files from specific phone models to this one, you never know.

Sure, but the OP stated the crashes are happening right after a factory reset, and anecdotal evidence on this thread suggests it's not widespread. It does point to some sort of hardware problem.
I'm having exactly the same issue!
I got the phone today and booted it up for the first time. I selected my language and as soon as I pressed get started it froze, then got stuck in a bootloop. I fixed that by factory resetting from within recovery.
Once I'd gotten through the setup it crashed again when I clicked on the apps button in the optional setup. Because of this I factory reset and set the phone up for a third time.
Third time I got through setup with know issues but the phone freezes/reboots roughly once every two hours. I've been searching all day to see if anyone else has mentioned this issue.
I guess this phone is going in for replacement. Does anyone happen to know how long that takes/ if I'm going to be without a device for long?
They told me 3-5 business days to get a replacement. I expect mine early next week.

Do you have to send the old device back first?

Well, I had the 6 Pro for about 36 hours. It kept rebooting randomly, even after a factory reset, so it's going back for an exchange.
Has anyone else had this issue?

I just had 3 random reboots today. Phone just laid on the side of my table on my laptop, doing nothing. It was in the span of probably ~10 minutes each reboot. A strange observation I made - now that I removed my phone from the back of my laptop and laid it directly on the table, no more reboots. Maybe it's a coincidence, maybe it has something to do with the magnets of my Laptop (has quite a lot inside). Not sure what to make of this. It kinda feels like a software buggy-thing, but it's odd that it sometimes just comees and goes. It also only appears to be in absolute idle. I had my phone working yesterday for about 12 hours, incl. using it constantly with navigation, and it never faltered for once. That's why I'd say it's a software thingy, if it had something to do with hardware, it would reboot/fail when under load. But it doesn't.
Had 4 total reboots as of now (had the phone since 27.10).
First reboot was yesterday (28.10) morning when working out, phone laid idle around, booted up.
And now again 3 reboots, morning, laid around, did nothing.
So I've had probably a dozen in two days. I take my phone out of my pocket and attempt a fingerprint unlock only to be told that my PIN is required after a restart. At first I wasn't sure if it was actually rebooting until last night. It prompted me for my pin and upon entering it, the screen locked up for about 20 seconds and it rebooted.
This morning I woke up and was yet again greeted with the "PIN required after restart" and less than 20 minutes later it was the same thing. Only once hav I witnessed the "G" boot animation, but everytime I see my UI loading. So I'm not sure if it's always a full reboot or some times it's just the UI crashing. Everything on my device is stock.

Did you transfer your old phone over with a cable, or backup, or did you start "fresh"?
Maybe we can narrow it down if it's software or hardware problem.

I did a partial transfer. I was coming from an iphone 12 so I transferred photos and contacts only. And I transferred via cable.
