[Q] Spontaneous reboots on the ZL? - Sony Xperia ZL

Has anyone experienced any spontaneous reboots on their ZL yet?
Mine has done it twice, both times while doing things related to Google apps or accounts. The first time my phone rebooted, I was actually adding my Google account after a reset to fix the notification LED issue. When I unchecked the option to backup and restore my Google account, my phone blinked the xperia logo, then rebooted (Sony logo, xperia logo, boot animation then done). It was a very quick reboot.
The next time, I was installing apps from the Play Store. A bunch of apps were queued up, downloading and installing over Wi-Fi. I hit the home button, then was about to open up a folder to check my Gmail app settings when again, the phone blinked the xperia logo and proceeded to reboot. When it was done, it continued to install my apps as queued from the Play Store, as if nothing happened. It hasn't done it since (of course, this was only a few hours ago).
My phone is not rooted & I have not messed with the bootloader unlocking or anything. It's 100% stock while I'm evaluating it against my SGS3 for a potential permanent switch. I've got the US C6506 model (black, on AT&T -- LTE is working fine).
I really, really like this phone so far, and I'm just hoping that these two reboots were a random oddity, not to be repeated.
Interestingly, I actually fully set up the phone yesterday evening, but when I discovered I had the notification issue, I reset it this morning and re-did all of it. The phone did NOT reboot at all yesterday in the 4 or 5 hours I spent playing with it, either. It sat in standby overnight without incident as well -- all prior to the reset today & the 2 subsequent reboots.
I guess from here it'll be a waiting game to see if it does it again, but in the meantime, I was curious if anyone else had seen anything like this with their ZL.

Yup, seen it twice myself. First time, I noticed that it had rebooted when I couldn't find any previously running apps. The second time I was in the Settings screen when it randomly rebooted. I was just about to click the Display setting when this happened.
I'm just running the stock ROM on the C6506 model. I'm keeping an eye out on it and will see if there is a pattern.

Thanks ... in some ways it's good to know, and in others, it worries me. I hope it isn't a pattern, though. Thus far, I've used the phone since the two reboots without incident (music playing, bluetooth connections, and phone calls).
EDIT: A third reboot. This time I had just updated a few apps in the Play Store, returned to my home screen and was about to turn my Wi-Fi off when it rebooted. One common thread thus far is that my Wi-Fi has been on each time. I have no idea if that's related or not, though.

I have been using mine for 1 week and have not had any reboots. I am using the hspa version (c6502) and I am a heavy user

Seems to me that the random reboots are isolated to 6506 models. I haven't had one single reboot in the past week I have been extensively using mine (6502). However, while I was on CM10, my phone hung and rebooted like hell.

Yeah I'm c6502 aswell no random reboots.

No reboots on C6502
Same here, have been using my ZL (C6502) for the past 22 days without a single reboot or freeze. Heavy usage for last week or so (wifi on all the time). I too think this and the low call volume issue might be specific to C6506 (LTE) version.

6502 here as well, no reboots so far and I'm rooted. Been about 2 weeks.

I'm starting to think this issue is unique to me and/or my phone -- at least my specific case. Actually, I'm glad for that, because I love this phone.
I realized I may in fact have memory card corruption. I'm going to explore that further, because I had some serious issues with my SGS3 corrupting microSD cards. I thought it hadn't done it on my current card, but I have discovered some corrupted sound files on it, so I think I'm going to do a format of my microSD and see what happens.
Thanks for all the input, folks!

I had some reboots in past one week
using since March 10th
today itself had 2-3 reboots
one more thing is had blank screen during a phone call also
we need Roms for this device I never understood
why there is so much delay in release of custom Roms

Once,
but not sure it was rebooting. Cuz the screen went blank. Then i had to press a tiny yellow button that says off near the sim slot. Then it came back to life. Plus my wake up button is kinda hard to press. Do you guys hv that problem?

I wouldn't call that a reboot, at least not in the sense that I was seeing them. That's more like a freeze that would require a battery pull on a phone with a removable battery (I used to have this all the time on the Samsung Captivate).
My ZL was rebooting fully right in front of me (screen goes black, then the xperia logo, followed by the full normal boot sequence, just very rapid -- the boot animation is shorter than a cold boot).
Note -- I have not actually fixed my memory card yet, and I have not seen any more reboots. I'm nearly a full day on my current battery charge, too.

I have the C6506 also, and I get numerous random reboots also. I did get few logcats, but I have not seen any revelant info that causes the random reboots. I replaced my micro-sim, thinking it may caused modem panic reboots, but that wasn't root of the problem. However, I did notice that the reboots occurred less without micro SD card, but I haven't completely made that conclusion yet (I want to listent to my music!).

I also have a 6506 and have been experiencing some kind of reboot. Not a full reboot that the OP has been talking about, but one where my screen just turns off. At first I thought better battery stats was just having issues as my stats would end up all out of whack for no reason. Then today the screen shut off while in use. I only had to push the power button to get back to my lock screen. But again my stays were all out of whack. I'll have to pull the log later but I hope this is is just a software issue.

Interesting. I've replaced all my corrupted files on my microSD card as of now, and so far, aside from that first day, I have not had a single reboot of the kind I saw before. Actually, no reboots at all, and my current uptime shows it (111 hours).
What happened to me was I had had a bad microSD card in my SGS3 -- files would become corrupted with time on it. I finally replaced it with a new one, but apparently when I copied my data back to it, I inadvertently copied a few of the corrupted audio files (notification sounds, actually) but never noticed it. I realized this when I was resetting my notification sound for text messages and heard the signs of corruption in the file, and so I began to think my phone had been responsible for the corruption. I know now that that can't be true -- otherwise I'd have some corrupt photos as well, and I don't. Only a few select sound files were bad, and because I keep regular backups of the contents of my microSD cards, I just copied the wrong ones (d'oh!).
Of course, I've had random reboots on android devices before (Asus TF101), so I'm quite wary of them -- if I see anything further, I'll post about it.

I looked at the log and saw nothing conclusive that would be making my screen turn off. I also checked my up time and it hasn't reset, so I know it's not a true reboot. When I put my SD card in I just wiped it from the phone. The only thing I put back was music files. Thinking about that now it wasn't the clean start I usually give my phones. So I just wiped the card again and we will see today if anything happens

C6503 here and I've been getting a couple reboots a day since I bought it. 2 days ago I used PC Companion to solve another issue (random loss of network signal) by reinstalling the phone software and that seems to have fixed it. Unfortunately the random reboots are still present.
I don't use any SD card at the moment.

I've now been using my ZL for a month or so, and since that first day when I made this post, no spontaneous reboots at all. I have no idea how or why, they just stopped on their own.

incredible restarting randomly

My incredible will restart itself randomly. There's no pattern to it, it runs fine when it's on or I don't see anything wrong with it. The only thing that may be different is that it hasn't been activated by verizon yet. Just wondering if anybody else is having this problem
Yes I do too.I have done two hard resets and it has not fixed the issue.
I plan on calling in for most likely a replacement this week. It's not the signal issue as I live in Ohio.
+1 random resets

etc. In addition there are plenty of posts on this topic on PPCGeeks, Android Forum, and IncredibleForum
Hopefully a fix will come.
I've had my incredible for about a week now with absolutely zero random resets.. maybe the newer shipped phones got a fix?
mine randomly resets when in low service areas
or
I believe mine resets randomly when the phone gets too hot (pocket, holder, etc).
Probably doesn't help much but two-three weeks ago my phone rebooted randomly 3-4 times over the course of about two days. It was always in an area with four bars of service and it wasn't overheating (to the touch).
Hasn't happened since then, though, so dunno.
I have had my phone for about a month and have not had a random reboot. I have had the HTC logo come up with a loading screen for a few seconds after shutting down progs with the Advanced Task Mgr.
I did not have any problems for the first few weeks but yesterday it rebooted on its own twice in two hours. Then it was fine the rest of the day. Nothing since then but I am watching it.

Ok, I take this statement back.. phone has rebooted 2 times in the past 2 days. I'm not sure whats doing it yet. Where I had the phone as I watched it restart is in a very low cell reception area.. I'm in the sticks so some spots in my house work better than others.
+1 for Random Rebooting , 2-3X a day
Once mine warms up it goes into an endless reboot cycle until i pull the battery. Make a call it reboots. Use the nav it reboots. I have perfect signal but the indicator jumps from 0 to 4 bars on all my phones like vzw has issues. Using my wm phone instead with no issues. Even not activated with a fresh rom flash it does it. What a pos.
I've had the phone for ~1 month and had ZERO random resets until I moved home from college. I always had full 3G service at school, but have 0-1 bars on 1X at home. I had two random resets today.
i got random restart until i pull out the battery.. finally i found the phone restart because of the sd card, i formatted the sd card then ok, but when moving the application to sd, the problem persist again, maybe it because some application cannot move to sd..

I've had this happen when putting apps on SD while using LPP. It apparently does not deal well when apps are on SD. Note: none of the apps I was using widgets and I read up on the LPP FC on reboot situation. But idk what the issue is for you but i've been able to reproduce a reboot when apps are on SD and I force a lot of CPU usage with LPP. Not an issue anymore though I just don't put apps on SD to be safe
after create partition on my sd using darktremor script for ext3.. my problem solve.. this is because the script in the ext3 informed to the system that the ext3 is phone storage..

Random restarts, lag, etc
I've had my Incredible for about a year and a half, and it's been rooted all along. I kept getting the "low on space" warning, so I applied the "Convert2Ext4_no_data_limit_normal_dalvik.zip" fix from another thread (http://forum.xda-developers.com/showthread.php?t=1488351)
But after applying this so-called "fix," my Incredible lags like crazy, randomly restarts, freezes, etc. For example, while typing this comment, it's trying to send a text to my wife, and going on about 5 minutes of the "please wait" screen while sending.
It's the standard incredible (ADR6300) running the stock ROM... :crying:

Nexus Rebooting Randomly

Its happened twice that i can remember now.
This morning in bed I grabbed the phone, deleted some emails, opened the browser and the screen went blank with the sound of a slight crackle. It then instantly revooted (google logo popped up etc).
Im concerned the phone is faulty. Is it likely just one of those things or does it sound more sinister?
Hope somebody can advise.
Mine rebooted once the other day. I don't necessarily think that the phone is faulty, it just has bugs that need ironing out.

it's just the apps
it can happen with any android device
just keep an eye on which app is causing it
you can pull out the logs and scan through it
I've been having the same thing as the OP. I get "Android is Upgrading" when it restarts, too.
In additiona I've seen (several times now) that when I press the power button to turn the screen on, it wont accept any input. After 30 minutes or so it spontaneously restarts and goes to the "Android is Upgrading" message when it restarts.
I'm on the verge of RMI'ing the thing as some of the other guys in the office who have it have not had the same problems.
I'm running vanilla sim free version, no operator tat installed.

Are you running a totally unmodified stock rom or have you flashed a custom rom/kernel/radio to it? Kernels are still being worked on and arent perfect yet.
Also Android 4 is still very new and alot of apps are not fully compatable and subject to crashing or crashing the system.
Everything will be ironed out in time

LG G3 D855 shutsdown on its own

Hello,
So I bought a G3 the day before yesterday and yesterday was my first day with it, and for that first day my phone had shutdown twice on its own. The first time was when my phone was lying on the bed and doing nothing, it had around 50% battery and was not hot or anything.
The second time was this night i don't know when, i have put my G3 on the charger and went to sleep i woke up and it had shutdown.
I didn't made factory reset when i got i from the box which i will when i come home from work and hopefully this will fix it, but does anyone have a problem like that? If is something serious i will be disappointed to return the phone.
p.s. My previous phone was galaxy s2 and had this king of problem only with custom roms and kernels, but i have not put anything on the G3 yet, except activating the developers options and had switched it to ART and the first time the phone had shutdown i thought that the art was the issue and switched it back to dalvik, the second time though was on dalvik.

I have the exact same problem. The past few days when I go to bed and wake up in the morning, the phone has shut itself off. I haven't rooted or installed any custom roms.
I would advise you both to take a factory reset, only install apps you need for a few days and see if the problem persists, if it doesn't install your apps back one by one as it may well be a particular app causing the reboots.
If you still get reboots after the reset and with no apps installed then you may have to take the phone back to swap it.

Yes as I said in the first post the factory format and hard reset will be the first thing that will be done as soon I am at home. About the apps i have pretty much basic apps (facebook, messenger, soundcloud, etc) all from the market except smashhit of which i have the apk and installed from the internal memory.
Except those apps I have 2 mp3s and some wallpapers and nothing else, becouse when i got my phone it was late on the evening and i had no time to do anything else. So the phone is pretty much out off the box and I was verry frustrated when the secound shutdown happened, becouse i tought the first was from the ART runtime.
Anyway today I will have more time to spend on the phone and we will see what will happend.
p.s. The phone does not reboots, just shuts off.

Is it definitely off or is the phone just stuck on a black screen? It is quite common on some devices when something is not quite right for the kernel to be unable to wake the phone up, the phone is still technically on but stuck in deep sleep.
does holding the power button for 2 seconds turn it on? or do you have to hold it for say 7-8 seconds?

It is definetly shut down around 2 seconds(the normal time to hold the power button to turn on) it turns on and work perfectly and does not show anything suspicious in its behavior, it's super fast, not laggy and etc, may be a little high on ram consumptions but with this havy skin i think it is normal or could not be normal idk, the ram consumptions go from about 1,2GB the lowest i have seen to up to 2,3 the highes i have seen.
Anyway about the shut off think yes defenetly 100% sure it is off, it happend again a while ago and i thoght the same thing may be it si deep asleep even i had chacked the weather 10 min ago and call myself from a friends phone and the operator said that the phone is off or i am somewhere without network covarage.
i got same problem. it turn off it selft and black screen even battery still 70%. rmust remove the battery to restart again, ealy bad. huft

If you have to remove the battery to get it to restart then its not actually shut off, its just stuck in deep sleep! which is usually caused by a bad app.
Yes if you have to remove the battery the problem is different, i just have to push the power button and it boots right away after it have shuted off by its self........
i didnt have this issue with my 855. but i did a factory reset after i got the phone just for the hell of it
So it's reset time i finally have some time to the some staff on the phone so hopefully everything will be fine. I will post if this fix or not the problem to inform the other people in this thread.

did you have any luck with the problem? I have the same issue, performed a factory reset and restored, hopefully it will fix too..
Hi all!
I have and have had the same problem and think I've pinpointed the problem to Google Search but can't 100% confirm it yet. I didn't do a factory reset when I got the phone and it shutdown during the night. I did a factory reset, made sure it got enough time to update everything properly. Problem was gone and worked fine. HOWEVER, the phone kept asking me which home screen I prefer at random times when I hit the home button. With random I mean like 4+ times per day. I searched the net and found a threat saying that a guy with a G2 solved the problem by removing Google Search updates. So I decided to do just that and get the factory version back and the questions disappeared but guess what, the phone shut down the following night.
Any takers or might this just be random? Note that it was working fine for three days with the updated Google Search and shutdown the first night after the downgrade.
So I did hard reset and so far so good the phone had not shutted down itself, and I updated everything which need to be updated (mentioning this for the guy with the upper post). So far so good I will keep you in touch if something goes bad...

I suggest take it to your dealer and get it replaced asap. I've seen lots of returned phones(my job at XXXXXXX company ) with the same issue, and as long as the defect is reproducible the dealer will give you a new phone. If it's outa replacement period then they'll probably repair it.
aaaaaaaaaaaaaaaaaaaaand shut down again but this time it took quite a bit time longer to shut off by its self so i tought the problem was fixed, but it's not, so i am going to the store which i buy it from to replace the device.....
Does this also happen with the korean models?

[Q] Device reboots after SIM unlock

Hi all,
recently my D855 with v20T (root/xposed) started to sort of randomly reboot. It seems like once the device gets too hot, it's gone.
Happens rarely during general usage, often while playing a game, and especially often when starting the camera.
But it behaves strangely in general: if I do *not* unlock the SIM (and thus can't use the phone), the device runs forever, without a reboot, no matter what the device temperature is. Same for recovery (TWRP), it can stay there for hours and heat up however it likes, no reboot.
Removing the SIM and/or microSD does not make a difference, battery level does not matter.
I pulled a backup of the stock ROM, wiped everything (system, data, cache, dalvik) and flashed Fulmics 5.
Unlocking worked once or twice, the next time I entered my SIM pin, the lock screen showed, then reboot. This behaviour (unlock SIM, reboot) repeats endlessly. If I leave it turned off for 10-15 minutes - or sitting at the SIM unlock screen - it most of the time works fine after unlocking.
Wiped again, flashed robalm's v30F ROM.
Guess what, exactly the same.
On both variants, the phone got rather hot during the "optimizing app x of 190" screen, but never rebooted, only after I unlocked the SIM.
Let it sit overnight on the unlock screen, no reboot at all. Unlocked this morning, added my google account, rebooted - same thing again.
It's starting to drive me crazy, now it froze right in the middle of setting up the google account after another clean flash.
Is the phone prone for repair, or can anyone think of another solution to this weird issue?
Edit: Fun fact: if I manage to do the lock screen swipe before the SIM lock screen comes up, the phone reboots instantly as well.
Edit2: Followed the instructions from this thread to go back to completely stock v20T. Rebooted after optimizing apps before I could even choose a language, ran seemingly fine after this, started bootlooping after the first manual reboot. A full wipe later (volDn+Power) it at least boots. What the hell?
Thank you and best regards,
Sub
I have similar problem. Cant connect issue with exact cause, but it restarts almost every few minutes of use. Camera launch causes restart almost immediately. Phone is unusable. My VolDn button is not working so I'm currently a bit afraid to try anything new... I updated from Fulmics4.1 (i havent got reboot problems since last 1,5week ago) to 5.1 but issue persists even after full wipe. Seriously dont know what to think about it.
At first I thought that reboots are caused by low power (much more frequent with battery under 30%), then maybe big cpu load or high brightness.... now basically everything causes reboots. Im really annoyed this phone been crap since day one...
I havent tried your sim unclocking method as my doesnt have pin security etc. Let me know if you will find out solution.

Just received the device back from LG, they replaced the mainboard, even got a new IMEI and v30c preinstalled.
It is the same case, with the protective glass on top and a dent on the left plus the 2-3 micro-cracks around the frame.
Not sure if they swapped the battery. The problem showed up again with anywhere between 50 and 15 percent battery left.
Unfortunately I only tested it after leaving the shop, after a long walk to the bus which I caught just in time.
Setup assistant completed -> reboot.
Google setup nearly completed -> reboot.
Removed SIM and MicroSD, started phone, started camera, made a movie -> reboot.
Wiped again (strange enough, v30c only has 61 applications to optimize while v20* has 190+?), tried again, same thing.
Next, after letting the back camera take a movie for 2-3 minutes, I wanted to adjust display brightness to the max.
Result: see screenshot. This also happened with the cable plugged in.
I will return it for repair once more tomorrow...
Anyway, thank you for your answers

Setup assistant completed -> reboot.
Google setup nearly completed -> reboot.
Removed SIM and MicroSD, started phone, started camera, made a movie -> reboot.
Wiped again (strange enough, v30c only has 61 applications to optimize while v20* has 190+?), tried again, same thing.
Next, after letting the back camera take a movie for 2-3 minutes, I wanted to adjust display brightness to the max.
Result: see screenshot. This also happened with the cable plugged in.
I will return it for repair once more tomorrow...
Anyway, thank you for your answers

It's a common thing if you use camera specially if you take video in 4k mode your phone heat up and you can't use full brightness in stock rom it's a feature try moded thermal config...also try new battery if battery percentage suddenly dropped it seems battery issue because i face the same problem....

I used to have thermals installed, the 75 dregrees Celsius variant, iirc.
Everything else was at stock, except for one short excursion to CM12 and one to ... some custom ROM.
Think I never actually took 4k videos, and the first 1,5 years the phone got a bit warmer but never really hot. Only recently it started to get really hot especially when using the camera, this also consistently was what could cause the reboot loops for sure. Other candidates were a few games which use more processing power like Alto's Adventure.
The battery drops by 2-3% after a reboot, because of the load the phone has (and the heat it develops during boot).
Anyway, I added the screenshot to the next repair request, and the woman at the counter said they'd look into the battery specifically (it seems to give out too much voltage, she said), but also check everything else once more.
I'll let them repair up to three times, then ask for a replacement, should be legal within 2 years after purchase in Germany.
Also, next time I'll take the 15 minutes (before doing a 1h/direction trip) to factory reset the phone, set it up and start the camera. If it reboots during any of this -> return, repeat.

Received my phone back from LG, finally.
Battery's broken - it outputs too much power.
Ordered a new battery and just put it in, so far no reboots during setup.
At least this got me a new mainboard and new IMEI

Hahahahahahahahaha
I just wondered why the phone shows 25 GB free everywhere, even without SD.
Turns out, during repair instead of replacing the 16GB/2GB board with an identical one, they installed the 32GB/3GB board
\o/ for LG

Random Reboots?

I was just wondering if anyone else has an issue with their Note 4 rebooting randomly with no external input. This started happening with the Android 6.0 update both on the download from here and the AT&T official release, Any Ideas? I've already purchased a new battery due to a separate issue, any idea?
I had the same problem. The phone would freeze and randomly reboot. Sometimes the system crashes and asked me for the typed-in password (not fingerprint). Sometimes when I charge the phone, and unplug the power cable, the charging led stays lit and the battery has to be pulled. I decided to switch the battery with my wife's Note 4 and see if the effects remained. So far I haven't had any problems after switching the battery, so I believe the battery may be the cause of all these issues. I'll keep you updated on the issues.
I'm back. The battery replacement didn't fix the reboots. I think my phone's hardware is permanently damaged. :crying:
have you downgraded?
and can you help me with my problem?[

I'm downgrading to stock 5.1.1 right now. I'll keep you updated. I placed an order for a Galaxy S7 Edge International Version (G935F) yesterday.

can you downgrade to Android 5.0.1 and help me with my problem?
its something completely different to this topic
I've been having the same issue, started about 2 weeks ago. phone would start being sluggish then if I continue tapping on screen, it'll reboot. At least once I saw it go into recovery & reinstall firmware(?). Another time it just sat at the bootloader screen waiting for software download or something till I took out the battery. Most likely it's a software issue related to 6.0 update or updates afterwards. taking out the SD card helped a bit.
but basically got annoyed & upgraded to LG V20 today. Coincidentally, there was another person at the AT&T store with a Note 4 having the same issue.
Mine just rebooted twice on me a while ago, first is emergency calls only now the reboots then what. And yes the slow charging is a problem too. MM got serious issue dam att

use wakelock its an app u get it from play store.it makes ur cpu always running.some how it fixes the problem of random reboots. dl it and set it to partial lock (the 5th option)
Same problem. Just started a few weeks ago. REALLY frustrating having to enter my password every 3-4 minutes. NEVER buying another Samsung, too many damn issues with this phone.
My reboots tend to happen once the phone goes below 60% battery. It's fine above 60%. Once it goes below 50%, the reboots tend to happen with any intense network activity. The phone will often go from 50% to 22%. I forgot what the 30's and 40's look like. I will try the Wakelock app.
Ugh. I posted about this a few weeks ago. It's started happening more frequently and will occasionally go into a boot loop or show 0% battery even though there's a charge.
Has anyone found any solution? I haven't tried wiping / resetting but I'm getting close to trying it.
Here is a cautionary tale for you. My completely stock, unroooted phone started acting the same exact way. On the 4th or 5th battery pull (to fix a frozen screen) it just crapped out. It's totally unresponsive. Deader than a door nail. Tried everything. The download mode, discharging by power button depression/battery removal, etc. Adb shell command does not detect it. Nor Odin. Computer throws up a qhsusb_bulk error when I plug it into pc. I have NO CLUE how to fix it & I am desperately seeking a solution. Please proceed wisely with your oddly acting phones & don't let this happen to you.

Same issue. Just got off the phone with Samsung support, all possibility of having this particular phone with this particular issue sent in for evaluation has been suspended. Translation, they know it is an issue and will not stand by the changes they push to their products (latest OS). I am researching the prospect of legal action since THEY pushed the new OS against my request. Shouldn't that affect the warranty or coverage? Consulting my attorney friends as we speak. Will let you know. I am not sure how WakeLock will help, it is not going to sleep, it is repeatedly power cycling through a kernel process until the battery overheats or it reboots.
Same issue
Since Marshmallow, my 910A will get sluggish or freeze, shut down, sometimes reboot and sometimes just brick (temporarily). Sometimes--more often in recent days, I get a "dll_mmc read fail" message and the target that says do not stop downloading. No matter what I've tried--factory and soft resets, cache clearing, battery pull, replacement, and SD card switch, contacting AT&T and Samsung rep--it doesn't seem to change. This is a daily issue and becoming more frequent. Any suggestions or do I just need a new phone? Thank you.
