[Q] How many of you are experiencing SOD issues on the Nexus 4?

Hello everyone,
I would like to know how many of you are experiencing the different kinds of SOD on the Nexus 4.
I found few references to the SOD issue, but no one could tell exactly why this is happening.
Some say it's a software issue (some say it only started to occur at JB)...
Some say it's an hardware issue.. some of them RMAed, and got a new phone with exactly the same SOD issue.
I would like to dedicate this thread to this problem and see how many other Nexus 4 users are experiencing this SOD.

Never had one so far. Running stock 4.2.2/Franco kernel nightly_110
-Edit- currently undervolted -75 mV.

just stop messing your phone up with stupid OCing and benchmarks... This issues are installed to protect the hardware from crashing... ( Red light of death... )

My phone just fine. never had this SOD.

Never had an issue on this device. On my old phone, dropping the min CPU speed too low would cause it a LOT.

You don't have an option for unable to turn on phone without a reset: no blinking led. This is also a scenerio.

Please take a look here! http://forum.xda-developers.com/showthread.php?t=2195278
I've tried almost everything (wipe& re wipe , install stock ) and nothing seem to solve it.... most frustatin thing is when I hit "home" after playing heavly and ...bamm it goes black screen & hav to reboot pressin home&vol+

Are you using a custom kernel to undervolt? That can cause SOD.

Im using it now (customROM&UV) since it doesnt affect my issue.... I tried completly stock for 2 days and keep crashin... or at least on g.earth as I didnt install any app/game to be sure its not an app related issue.
Cant figure out what happens, it can play games w/o any issue, but sometimes when I change orientation it just goes black
PD: I dont hav enough time, but ill do a logcat to see what can possibily make it freeze

My case is not listed in the poll options:
- the phone went into standy, good battery, no calls, no high loads;
- LED was inactive totally.
- then I was unable to turn it on normally (only through reboot).
While in this state, trying to call the phone resulted in "long" tones, i.e., like the network saw the phone. The phone did not ring.
This happens with the latest stock firmware on the 2nd day of my use. Non-reproducible. Phone returned.
Would be delighted to learn if that's a hardware or software issue

Not necessarily SOD but experienced extreme battery drain under these situations
1- Charging via USB and left phone connected after PC shut down.
2- Charging via Wireless Charger left it on the pod.
In 1st ASA pc is shut down
and
In 2nd ASA Phone charged completely , as I suspect the charging process goes backwards ! It someone drain current from your battery to the power source.
AFAIK none of these issue are positive with normal good old AC charging. However you can still use a workaround by using the app called "Safe Charge"
This is my experience

[Q] A very strange issue with my battery

Hi.
I have been having very strange issues with my battery, and I hope that there are some people here who know about the hardware more than I do and might be able to help me.
First of all, the battery indicator is unstable, it can show me 49% of battery and suddenly tell me there is only 10% left. I am attaching a screenshot of my battery stats where those spikes are visible.
Or worse, the battery indicator might suddenly jump to 0% and make the phone turn off, then when I turn it on it shows that it has at least 25% left.
Second problem, I very often can't charge the phone. I connect the charger, and the notification LED doesn't light yellow, instead, the whole battery menu just disappears from the settings so I can't access it... And after a few hours it might begin actually charging, then the menu is visible.
Battery temp always shows -30 degrees celsius, or some similarly impossible temperature.
After trying to switch to a different kernel (from unleashed to hells core) and to a different rom (from purity to android L and liquidsmooth) I decided this is an hardware problem and bought a new (hopefully original) battery on ebay.
I installed the new battery. Now it does work a little bit better, but still, the problems persist.
Is there anything I can do, before buying a new phone?
It doesn't have warranty anymore, it's one and a half years old.
Thanks

Definitely battery failure. Replace the battery or buy a new phone

This is most definitely due to a faulty battery, so time to get a new phone. At least Shamu's release is right around the corner.

Hi
Thanks for your help.
I did replace the battery a few days ago, and the problem still persists. Which makes me think it's something else.

I'd try comletly stock rom, and see if the issue persists.

Yup, stock ROM always first step, then replace battery. If it still persists, than it is most likely some other hardware issue that might not be worth it to replace.

Exactly same situation with my Nexus 4. Battery being replaced and it's not better. Just ordered a Moto X 2014 and waiting for it.

I tried the stock ROM. And it didn't solve the problem. Is there anything else I can check about the hardware before replacing the whole phone?

Have you just flashed a stock rom, or completley restored the phone to factory settings using google factory images?

Hmm unfortunately this leaves me without any ideas. May ask how old is your phone and did you drop it previously?

It's one and a half years old, and well, I did drop it a lot.However, I always used a good case (ringke fusion) and I don't recall any recent drops prior to the time the problems started.

Battery drains like whatever...

I've tried two different ROMs but the problem with battery seems to be in two of the latest Roms one is near 2.5.4 (the latest one if I quoted wrong) and second one is X-note v4 and now v7 these are ones that happen to have battery draining problem.
It happens whenever i use camera and then close or get out of it and after an hour or so whenever i check all ic is my battery is dead. Is there some fix for this problem or are we stuck with it forever?
Thanks in advance for your help.

Bump

It's a 4.4.2 firmware problem. This qq camera daemon makes phone hot and drains battery like hell. Sonetimes i have same problem: the only temporaly fix for me is to pull the battery out of phone for a few mins

I'm looking for proper fix is there any fix that can take care of this forever? You need not to take battery just restart your phone or max shutdown that will do the job till next time.. wonder what is causing all this and how can it be few of us only? Whilst the firmware is out in millions of phones in various varieties of phones...
We really need this fix if anyone has fixed this issue please share so others like us can benefit...
Thanks

Still looking for fix...

Fingerprint (again)

Hi,
I know this has been discussed many times, but I have something more to share regarding this, and maybe it can help anyone find a solution.
My X820 arrived last Friday, bought from Geekbuying. It had Indian 19s ROM, although it might be slightly modified by the shop.
Fingerprint was working well, but I wanted a better and more optimized ROM, so I flashed TWRP and got Small EUI. The worst thing is that I forgot one important step (yes, backup) and flashed the ROM right away.
Fingerprint kept working, but got worse. On Indian 19s, it unlocked the screen or apps very quickly, but on Small EUI it took it 1 or 2 seconds, so on Sunday morning I tried the calibration option under settings. That's the moment the fingerprint scanner stopped working. I spent some time on Sunday, and most of Monday trying different ROMS, but nothing worked. The sensor would not react at all, and would not let me add fingers.
Yesterday, I found a thread, on a OnePlus 2 forum, where people described a similar issue on that phone, and the way they got the sensor to work again: they drained the battery down to 0%, to the point when the phone would shut down by itself. Then they charged the phone again, and the sensor came back to life.
I tried that (I'm now on Cuoco92's 93c ROM), and after turning the phone on again, the sensor seemed to keep failing, but there was a difference. Before that, it wouldn't react at all, but this time, a message instructed me to keep my finger on the sensor for a longer time and to try again. This message was not appearing before.
I left the phone alone for the night, as I use it as an alarm clock, and in the morning I tried again, and it worked. I was able to register fingers and the sensor began working as usual, and unlocked the screen almost instantly.
But now,. two hours later, it is dead again. I've noticed it doesn't unlock the screen. I've just tried to remove the fingers I had registered earlier and see if I can add them again, but it doesn't work. This time, there's no message that instructs me to keep my finger on the sensor for a longer time, or to try again.
Well, I definitely haven't solved the issue, but I may have found something. Maybe others with dead sensors can try this solution and report back.
To drain the battery, I used this app: Your Battery Drainer
P.S.: BTW, I decided to try draining the battery because I remembered that when first I got the phone, the battery was empty. I almost freaked out when I tried to turn it on for the first time, as it wouldn't turn on, but it turned out to be that the battery was empty. After I left the phone charging for a while, it turned on normally.

I also just got my phone today 6gb RAM, 64gb UFS2.0.
Fingerprint very fast with 19s ROM.
I think I will stick with this ROM forever.

You should, that was my mistake (I think) besides the LeEco software, and maybe fp hardware, not being too good. I just flashed the stock Indian 19s ROM again and the sensor is not working. I'm now downloading the Chinese 16s version, which others reported helped them revive their sensors. If the Chinese ROM doesn't work, I'll flash the Indian ROM again and try draining the battery in the evening, as I did yesterday.

Good investigative work. I wish you good luck and will be reading this thread until you get it working.
I am quite happy to get this for USD186 for current x820 version even though without headphone.

Will wait for your result . 19s is actually badly optimized. I got 99k in Antutu.

I try every method with roms with apps but fingerprint newer works.
today i read this thread, i try now to drain battery with this app and i cant believe fingerprint start work.
But how long fingerprint will work.

Is there a possibility quick charge 3.0 heat kill the fingerprint sensor? Did you enable quick charge in the menu? Mine one still disabled and I am now worry to turn it on.

That might be it. Today my sensor is not working, after draining the battery, but last night, when I charged the phone again, I did it with the fast charger. When I have the time, I'll try again with a pc or just disabling fast charging. Maybe you have a point there. Nice one.

You mean the modem files, don't you? That was also one of my next steps, but first I'll try draining the battery again and not using quick charge afterwards. When I first got the phone with an empty battery, fast charging was not enabled, so it took the phone ages to charge, but the fp sensor worked. I think we may be close to a solution for everyone, and something LeEco should know. Maybe they can implement an slower fast charge which doesn't interfere with the fp sensor.
Anyway, fp sensor was not my main reason for purchasing this phone, so it's not that high on my priority list.

As another user suggested, disable fast charging, if you have it enabled, and see if fp sensor keeps working afterwards. It's good to know this method worked for you, too

Well, after flashing the Indian 19s ROM and draining the battery, nothing changed, but it could still have something to do with fast charging. Although I had it disabled, when I plugged the phone in, using LeEco's original charger, it charged the phone fast, rather than slow, so I think that maybe it didn't work because of that. I'll repeat the process again, this time using an old regular slow charger.
Did anyone else tried? Did you succeed?

I scared that quick charge heat already kill the finger print. I mean hardware is dead.
But I still support support experiment to fix the fingerprint.

I think the FP problem has to do with HEAT. The FP failed to work when I was on holiday in Florida a few weeks ago. When I returned to the cool Toronto ,Canada, it is back to normal - works most of the time.

Fast charge generates a lot of heat, that's why it's our main suspect right now

Did you flash 23s modem? not the rom, only the modem and after the update of modem clean install of the rom ?

I have tried.. draining all battery from 25% to 0% and smartphone Switch off and after i charged almost 50% without fast charge and tourn on but unfortunatly fp still dont work

Listen guys, I hate to burst your bubble, but I have to... For starters, there are MANY people in the forums flashing all sorts of ROMs and different things, and their fingerprint readers still work. I can say the same thing for Quick Charge 3.0, everybody uses it, so I highly doubt that either of these things are causing the hardware failure.
Also, remember that OnePlus uses Dash charge and all heat is relegated to the charger and not smartphone.
I own two X829's that I bought from Banggood for $196 each a few months ago, and the fingerprint readers still work after countless flashing and charging, and believe me the phone has gotten incredibly hot at times too.
Early on though, I thought that my fingerprint reader had died because it stopped working on when I moved to the Nougat ROMs and later I found out that I needed a more recent modem for the fingerprint reader to work (23S or 419D), but what I have done in a panic was contact Banggood and I told them that my fingerprint reader had died on both my phones. I told them that I had already troubleshooted and consulted the forums. I told them that it was a common defect. I made a YouTube video for them showing the problem. They told me that I could return it to them to China and that they would refund me, but I told them that it cost too much to ship to China and that the last time I returned something to them it got lost in the mail. They then said that I could take the phones to a local repair shop and that they would refund me the cost of the repair, they said that the most they could refund me was $116, so I made a fake invoice for $116 and send it to them because I had bought two fingerprint readers from AliExpress for $7 each and wanted to repair them myself.
In the end I never needed the fingerprint readers because I was wrong and sold them on eBay, and Banggood refunded me the $116 for the so called repair, so in the end I only paid $82 for my Le Max 2. Hope this helps!

leeco pro 3 x727 shuts down after few minutes

This happens only when I install any custom rom...the phone works fine with x720 5.8.018s version...anything apart from that device will shut down every 2-3 minutes ...very strange behaviour ...any one has any idea ?

any custom rom , android 6 or 7 , AOSP or stock based, it will boot fine and after initial setup , it will work for 3-4 minutes and then suddenly device shuts down. .. when i boot it up again , same thing happens, in one minute shuts down.
if i flash 5.8.018s stock rom , everything works fine....and it doesnt shut down...

After device bugs, my phone finally was restored into x720 stock ROM (i have x720). On boot it worked below 1 minute and reboots. I had to do clean data. Also booting x720 ROM into x727 is not too good idea. Maybe you should try to do more wipes?

I did all the wipes i could , cleaned all kinds of data... it was US version 5.8.018s originally and i tried to flash Omni ROm first , and other ROMS , all had same issues, so i thought going back to the stock US rom , but since US version of 018s is not available anywhere, i went to chinese version , and it works perfectly , no reboot/shutdown...... I have used number of phones and installed 100s of ROMS , i have never faced soemthing like this...i hve even used leeco pro 3 before, with all custom roms and no problems.

Ok update...i downloaded x720 021S and 023S and updated using in build update option..(local update) , and it worked, 23S is working without any shut down...so i guess, it is problem only with roms flashed thru TWRP

Usefull information, thank you very much.
Nearly the same problem here: My X720 is only rebooting sometimes, but more often switching off directly (vibrates one time and switches off). While the phone is in that status, the battery is discharging. I can only reboot the phone by holding the power button for about 10sec or to TWRP. Two times I was rebooting the phone and some (not all) settings were restored to default - reflashed the rom... Another time rebooting the phone it hangs in the booting display, did not get it booted completely again - reflashed the rom.... Very strange behaviour and don't know why this happens.
But for about the last month, the phone is only switching off and I can reboot and use it for an unspecific time.
That all happens with several ROMs - currently I'm on ResurrectionRemix 5.8.5. This is the most stable custom rom I have tested, but anyways the phone switches off in irregular periods. Sometimes the phone is about a day alive, sometimes only a few hours, sometimes below an hour. When I'm playing HQ games I think the phones switches off much faster, but not sure.
I'm also not sure - I do not have used the stock rom really long after I get this phone (was CN 5.8.018s I think) - but my feeling is, that the phone was definetely more stable with the stock rom.
Now after finding this thread, I will give the stock rom another try. Would you be so kind as to describe the process of going to the stock 023S a bit more in detail? First flashing the 5.9.021S for the x720 ROM throught TWRP and after that using the build in update option (rename file to update.zip into root folder)?
Thanks!

Does anyone completely solved the shutting down issue on x720? I remember the same issue with the stock rom when i was getting the phone (5.8.018). but this rom could have been a shop rom, cant remember.
For me it seems that the issue happens more often whenever the phone uses more performance. Playing HQ games let the phone shut down after about 1-3min. doing nothing on the phone, it remains for about a day. Weird behaviour... will try to flash the stock recovery via fastboot and then a stock rom (no shop rom). hopefully it will improve the behaviour or even better solving the issue.

Sounds like a hardware issue. As for me, I have a couple of screen issues--I usually have my LeEco Pro3 Elite connected to a charger, and I sometimes don't use it for long stretches of time (say, 8 hours) because I have another phone as well. Once in a while, during those times the screen refuses to turn on. Sometimes the fingerprint scanner wakes it up, other times I have to straight up reboot the phone using the power button (I have to keep it pressed for two whole minutes for it to wake up the phone). Pretty annoying, dunno why it's happening. Could be a loose screen cable.
Now, if your phone is shutting down every few minutes no matter what, it could be a battery issue. I say this because I had a similar issue with an old iPod Color from 2005. The iPod would shut off every few minutes even when plugged into a charger. I changed the battery and it stopped shutting down.
Hopefully it's not a motherboard issue because replacing a phone's motherboard is never easy.

I don't think gameplay should affect the phone negatively at all. Especially a phone with a Snapdragon 821, a 14nm processor with efficient cores, for crying out loud. I play Fate Grand Order, a pretty intense 2D online game with 1080p graphics for 5 hours straight on my LeEco Pro3 Elite (Snapdragon 820) without it heating up at all.
Again, seems like a hardware issue because no phone with a Snapdragon 821 or 820 should be doing that. Especially while gaming.

Thanks for the information.
Could be possible... If I'm shaking the phone like a cocktail-mixer, it feels something loose inside it and this could be the battery of course which could be not fixed correctly. But I am sure, that this issue has also something to do what is happening on the phone currently. Sometimes I am going to bed and the phone does not move for 8hrs, it simply lays on the table. In the morning, it is shutted down. Need to hold the power button for about 10sec to restart the phone (usually hold 2sec to power on). Sometimes (not really often) it warm-starts automatically.
I think this could be also a memory issue or internal storage. Yesterday I was playing a game (Bowling by Jason Belmonte) and after 3min, the phone hung up, display remains on, no reaction on pressing the hardware buttons, waiting 5min... nothing happens. So I pressed the power button 10sec, phone seems to reboot normally, but it take a bit more time in my oppinion. Now after entering the pin, some phone configurations were resetted to default, but not all. Playing this came, it sometimes happened, that the phone switches off (with one vibration). Rebooting with a 10sec press and it runs again normally. This time phone hung up and some configurations were resetted to default. WTF?
Today I have played Hmmsim 2. Phone hung up again, pressing the power button 10sec, phone begins to reboot, but rebooting never finished (waiting for about 1-2hrs). Long Press power button (10sec) to try to reboot again - same behaviour, never ending ROM loading screen. Wiped to factory via TWRP and the phone reboots again, but all configurations lost, like freshly installed rom. OK, whatever, using the google backup for apps and so on... when installing the apps in the background, the phone reboots about 3-4 times, app installations not finished. Cancelled and shutting the phone down to TWRP, where I am now...
What I will try to say is, that whenever the storage or memory is used to much or something like that, the phone begins with that behaviour.
And now I am thining about what to try next. I think I will try to flash the stock recovery via TOOL ALL IN ONE then flashing a stock rom like 5.9.023S.
I am still not sure of a hardware issue...

The easiest way to tell is if the issues were occurring before you flashed TWRP. Were they? This is why you always wait a couple of months before modding your device. Otherwise you'll be stuck in a loop of doubts. By this I mean you'll be convinced that the issue has to do with your custom ROM or kernel rather than your device's hardware, but you have no way of knowing for sure because you never used the phone enough on stock firmware.
I was like you... my unmodified Zenfone 3 had a screen flicker issue and a headphone jack issue that I was convinced was a Nougat problem. I upgraded from Marshmallow to Nougat immediately after getting the phone. After a lot of research and posting threads on the Zenfone forums, I realized I had a hardware issue on my hands. The screen had to be replaced for the flickering to stop, and the headphone jack had been gimped to 0.3v by ASUS for some reason. I quickly sold the phone and got my LeEco.
Here's a thread I made on XDA about my screen flickering issue. It's a hardware issue: https://forum.xda-developers.com/zenfone-3/help/ze552kl-screen-flickering-lowest-t3660643
I've learned some important things from that experience: it's easy for your brain to trick you into thinking you've got an easy-to-solve software issue on your hands, when in reality you've got a hardware issue. You need to start making arrangements for a replacement device and get video evidence of your problems to show to the seller ASAP. Because that behaviour isn't normal. Now I hope you do have a software issue on your hands that the stock firmware will solve, but who knows. Be prepared for anything.

Thank you very much!
I am sure that the phone was doing the same on stock rom, but maybe fewer times. I have flashed a stock based rom now (Turbos mini 5.9.023s) and the issue still exists, but now the phone reboots normally more often than going into edl mode (emergency mode). I have found an old thread here on XDA and the issues described there sounds nearly the same. Finally the user in this thread also had hardware issue.
I believe also in a hardware issue, but I am still not sure. If I am looking to other threads regarding similar problems, there is always some regularity in the behaviour or the reported issues. In my case these rebootings (usual reboot or reboot to EDL mode) are definetely very unregular. On the TURBO Rom, these reboots happen definetely more often when the display is off and the phone sleeps. On the TURBO Rom, playing games seems to be helping lasting the phone a bit longer, the completely differnce to ResurrectionRemix Rom, where the phone was lasting longer when doing preferabely nothing. The issues are so inconsistant and this is making it hard to believe, that this is a hardware issue. Why the hell is the phone behaving different on every ROM - if it's a hardware issue, the occurred problems should have some regularity.
As I didn't have an OTA update option on the stock rom, I'd found out that this could be a "shop rom" (5.8.018), which is not the best choice nor for the first month(s).
I'm from Germany and I do not really want to return the phone to china or east asia for repairing (bought at banggood). This could take a very very long time. Changing to a new one could be also difficult because there are hardly any more devices out on the market and I need to return it for the change too.
But I am slowly at my wit's end and before these issues are making me more and more crazy, I will accept a problem with the hardware.

If your issues were occurring from the moment you got the phone, you know it's a hardware problem. Your seller sent you a defective phone and you should at least try fighting for a partial refund. If you paid through PayPal, open a dispute. If you paid with a credit card, ask for a chargeback. Now, the shop you bought it from might ban you for initiating a chargeback, but it's probably worth it. Or you could just cut your losses and move on. Maybe donate your phone to a dev who wants to try something crazy. :good:

Oh snap, it's a Banggood phone? I bought my x722 from Banggood. No glaring issues other than the screen one so far, but this does worry me for the future. How long have you had it?
This is the problem with Chinaphones. They're cheap, they've got good specs, but you can't guarantee quality. Especially with now close-to-defunct brands like LeEco. If you're still okay with Chinaphones, get a Xiaomi next. Probably the most reliable Chinaphone brand out there, next to Huawei. And try to buy from an official source. I heard The Solution Shop in Europe sells Xiaomi phones for cheap (?). And always remember to record your unboxings and document all issues from now on.

Admittedly I'm not sure at all if this issue was already present after starting the phone for the first time. One of the first things I have done during the initial setup wizard was using the integrated data transfer app by LeEco (scanning a QR code with the old Xperia Z, downloading app to transfer data to the x720). This app establishes a Wifi direct connection between both phones to transfer the data like apps and other stuff. This transfer process takes at least 6-7 hours and during that process I am sure that the phone was not rebooting a single time. Maybe a specific app or background process of an app causes this irregular rebootings. I have not testet this. I have installed the most common of my apps also using different custom ROMs later.
On the current ROM (Turbos mini 5.19.023s) I have now looked into the last_kmsg.log file severel times after the phone was hard-rebooting (not to emergency mode - the phone is switching down to emergence mode really rarely since I have flashed the stock based ROM) to debug for a kernel problem and the power off reason seems to be ""Triggered from PS_HOLD (PS_HOLD/MSM controlled shutdown)". In the log file I could also find some "kernel panic" entries. So I have a little gleam of hope that the issue is not a hardware problem. I have to test a bit more with the stock recovery/ROMto gain a better knowledge of the issue. I think I will post this into the ROM topic to ask a developer.

Finally - I got it working without any problems now!
Happily it seems to be not a hardware issue. I have flashed the Grossoshop ROM and Recovery via a provided .bat file. This .bat file has flashed the recovery first via fastboot, then the ROM via fastboot. This Grossoshop ROM was based on 5.8.018s I think. Then I have updated TWRP Recovery to the latest version via TWRP itself (flashed the new image). Then I have flashed Mauro's 2.2 (which is based on 5.9.023s) and it is running great! Super performance, no extrem battery drain, no reboots, all is working (except the chinese design downloads as I cannot create a Leeco account from Germany). But now I'm satisfied. :good::laugh:

Usefull information, thank you very much.
Nearly the same problem here: My X720 is only rebooting sometimes, but more often switching off directly (vibrates one time and switches off). While the phone is in that status, the battery is discharging. I can only reboot the phone by holding the power button for about 10sec or to TWRP. Two times I was rebooting the phone and some (not all) settings were restored to default - reflashed the rom... Another time rebooting the phone it hangs in the booting display, did not get it booted completely again - reflashed the rom.... Very strange behaviour and don't know why this happens.
But for about the last month, the phone is only switching off and I can reboot and use it for an unspecific time.
Thanks!

My x720 has done the same to me a couple of times now, Vibrates once and turns off and I have to hold the power button for a few seconds longer to turn it back on again which is odd.
The battery was charged over 50% % 70% at the times it happened and I wasn't even using the phone, It was just sat on the table in front of me.
I didn't have any problems at all until a few days ago when it first shut down.
I'm using Oreo - AICP 13.1 from here - https://forum.xda-developers.com/le-pro3/development/rom-aicp-13-0-pro3-aka-zl1-x727-x720-t3698058
The problem now is I don't know where to start troubleshooting When I get time I am planning on a clean wipe and fresh install of AICP again to see if that solves the problem

When using this ROM does your phone heat up a lot.

Did you manage to fix the problem somehow?
