How can I distinguish SOD from ShutDown? - Nexus 7 Q&A, Help & Troubleshooting

Hi All,
I have a rooted/custom ROMmed N7.
For some reason, most of the Custom Roms that I'm using just makes my N7 SOD. It usually happens if I have in activity for more than 2 hours but I also had some right after a few minutes. I've used different ROMs with different kernel and it was all the same. So it usually happens more than 5 times a day.
Now it came to me that my N7 could be defective since I can't tell if it was shutting down or SOD. I never had heat issues with so I don't think it is shutting down because of heat.
Is there a log somewhere that I could find that would say that my N7 had an SOD or a shutdown?
Thanks!

a sod is when tbe device is still alive nut the screen wont turn on, kind of like a coma. a last_kmsg will document a shutdown or reboot, but not a sod(since a sod doesnt reset).

Random Shutdown

When my phone is sitting idle (screen off) it will randomly decide to power itself off. Has anyone else noticed this? Any ideas on what could be causing it?

you mean randomly power itself ON, right?
if that is the case, it's normal, it just mean it woke up to connect to the internet, to get updates of news, emails, or whatever it was scheduled to pick up
nope. i mean it randomly turns itself off. this topic is being discussed over on the att captivate galaxy forum section.
interesting, so it's going from stanby mode, to complete OFF... nope never seen that happen to my i9000 model
yep totally powered off... completely sucks... looks like there are a bunch of ppl that have this issue with the captivate on att. $10 says its some lame piece of software that att puts on your phone that's causing the problem.
it's possible, i've read here a few users having crazy power issues (battery draining very fast) with their SGS i9000, but after wiping it out clean, to start anew, then the power problem is gone away.
so yes, a software could cause something weird like that.
Factory reset and so far so good
Hey guys,
I use a Galaxy S here in Hong Kong and I had the same random shut down issue constantly happen when my screen went off...
I tried everything, check temperature of cpu, etc. etc. and nothing worked, it just got worse and worse.
I even changed the battery to use the spare one that came with this. Still problematic.
Used SET CPU to limit the cpu to 400mhz, still problems.
Finally I did a factory reset and so far so good.
I only have the original system installed with the Remember the Milk app installed.
24 hours, no problems.
Installed AppBrain app.
Then I installed 3G WatchDog
12 hours, no problem.
Then I installed Paperdroid
12 hours, so far no problems at all.
If I run into an issue I'll post it here. But I think it definitely was a software issue.
Update - it randomly shut down on me
Alright guys, it shut down on my randomly today in the afternoon......
I dont know if it's the re-charging that screwed it up?
Because after my factory reset, last night was the first time i charged it....
Hmmm
This happened to me too - two days in a row until noon it would shut down two or three times - i uninstalled SetCpu and for now (24 hours) it hasn't happened again. I am not sure if it was the one responsible but it started happening after i installed two programs and i uninstalled them after it started happening. I uninstalled Visual Task Switcher first but on the next day it turned off again, then i unsinstalled SetCpu and it hasn't happened again - maybe some wrong profile settings but i didn't feel like experimenting
I had this issue once too in about 40 days.
I was reading an sms and then i turned into standby and put it in my pocket. Later, maybe 40 minutes i came home and my phone was completely off. I do not remember if i had to take out the battery before to get it on again.
I was wondering why it happened. Maybe it was caused by an app i had opened. Battery still was at 40%.
But since it only occured once in 40 days i doesn´t bother me.
Interesting you mention this as it just happened to me today for the first time. I took it out of my pocket and wtf? The phone was off. Very strange... Using the i9000 on the stock Eclair rom.
Should send back for warranty

software clash?
Well the phone suddenly switched off for me, but this time I turned off APPBRAIN and so far so good.
In fact, I came across an app called NoLED and since it kind of keeps ht phone on, while I have it on my desk, I'm able to be notified of stuff and so far with that, the phone hasnt' shut off.
I'm still experimenting with what works, but try turning off AppBrain and see if you still have the random shut off issue....
i use app brain all the time to keep my apps in sync
not the cause of the problem, that's for sure
my phone can last a whole day even with app brain running
OP, do you have MSN Talk installed on your phone? I have this same problem, seems to happen more when I am running MSN talk in a low signal area.
«try a new sim card. «Could be faulty. «i am on my 3rd phone and all of them had this same problem. «i bought a new sim card 4 days ago, and hasnt happened since. «but then again, this problem usually happens to me once every 3rd-5th day anyways, so i dont know if i am in the clear yet.
Me too, shutdown everyday
Hi guys
After upgrade OS to I9000ZSJG4, Phone random shutdown everyday.
Yep still shuts down
Tried keeping AppBrain off, still shuts down.
Used NoLED so the screen kind of stays on, still shuts off..
So far shut off on me after 40 hrs... this is really stupid.
I am this close to taking it back, but I genuinely think it's a software issue than a hardware issue...sigh
Anyone have any luck figuring this out?
Same problem no solution yet
Hi
I too have the same problem, haven't found any solution yet.
The temperature etc is all good, there is no pattern in shutdown issues.
I have tried factory reset and no new application, it still shut down while using in built browser.
I had the same thing happen to me while skiing in Whistler last weekend. It died twice. I attributed it to the cold. I normally use a 3000mah battery up there, but left it back the house that day. Afterwards while charging in the car and even charging it at home it died prematurely again. It was the eBay aftermarket variety 1500mah knock off. I have since changed back to the Samsung OEM battery. I haven't had an issue with it since. My assumption is that the knock offs in my case cannot handle the heat cycles of charging and then the cold as well as the original. Or they have a limited lifespan, well below OEM specs. I am now only using the 3000mah battery on the weekends to hedge my bet on the quality of manufacture, as it seems to be from the same factory as the 1500.

Current problems with CM7

Debating about whether to install CM7, but there have been a few problems with it. I'm having a tough time finding the current state of the following issues:
1. Sleep of Death - Nook goes to sleep and doesn't wake up, forcing a reboot. There seems to be some debate over whether this is solved. One of the threads indicates that it's not a problem if you turn wifi off with the screen. Can anyone confirm?
2. Battery drain - Battery drains at 2%-3% per hour in sleep mode. I believe this is resolved. Can anyone confirm?
3. Premature Battery Death - Battery dies at various points over 0%. There seem to be various utilities for resetting battery stats, etc., but I can't figure out whether or not this is resolved.
4. Screen stays on when plugged in - Forced to hit the screen off button when plugging in the Nook. I've seen recent complaints about this one, so I'm assuming it's not resolved.
I did go through the threads and am confused about whether these issues still exist, so I figured I would try the Q&A section. If someone with CM7 wouldn't mind jumping in, that would be great. Thanks!
1. Maybe, I'm a lucky one but I haven't had problem with SoD regardless wifi on or off. I've been using nb100 and up, and now at 138
2. Using 138, i got 2-3% drop overnight, about 8 or 10 hours. With 120, zero dropped
3. Not experienced yet since I never let it down to sub-5
4. Mine seems act the opposite way: screen off, plug in to charge, screen automatically on, have to press power button to put screen off again.
1. I haven't seen this in recent nightlies.
2. Fixed; NC now deep sleeps when unplugged, even with WiFi on.
3. Fixed as far as I know.
4. Mine acts like yours and votinh's both; these are not mutually exclusive. If you plug in while on, the screen eventually dims instead of going off. If you plug in while off, the device turns on, sometimes just the backlight. I'd call this one minor, especially in relation to the other issues.

1) I get SOD about once a day regardless of how I have it set up. It does happen less with wifi on sleep only but at work I need to push data, so my wifi is on all the time and...it's an issue, not terrible but annoying none the less.
2) Battery drain, I get about 36 hours if I use it lightly, but I tend to charge it nightly because I can't take a chance of heavy use at work and loosing it.
3) PDB, never had this problem.
4) The screen turns off by just hitting the screen off button. This isn't a big a deal actually, since you gotta plug the thing in, another button isn't a big deal. I have katecca screen lock and off in my bar at the bottom, so it's easy to turn off. I also have the nook power off widget but I haven't used it much.
That's great. Thanks a lot for the responses. Really helpful.
I have only had it CM7 on my nook for one day, so im not sure about the battery issue. But i know i put it down around 10pm last night with less then half a battery and i got home from work around 3pm and it had about 25% batt left.
Besides that sometimes when i plug it in it stays lit up. but thats a "meh who cares" to me at least.
Running 7.1.0 RC1 with Dal's OC, On Demand, with lowered Voltage on the steps
1) I've only had one SOD ever (knock on wood), it seems to be mostly cleared up
2) Battery drain has not been a problem for me. On .29 it was more only 1%/hr for battery drain.
3) I haven't experienced early battery death at all
4) It isn't a big deal, especially if you charge with the provided outlet adapter for quick charge. Don't see this preventing you from installing CM7.
If these stats are correct from ASI (I'm hoping they are, they sound right), I'm at 76% after 3 days, 19 hours uptime, and 7 hours of it without sleep.
I say go for it. Even if it is off SD (mines on emmc) it is still a much better experience than stock/rooted. I doubt anything will make me change from CM7, unless ICS becomes a viable option in the future.
Just a follow up on this. I installed CM7 and have not had a Sleep of Death, have normal battery drain comparable to stock rooted, and have not had premature battery death. The screen does come on when I plug the Nook in, but like everyone mentioned, I just turn it off and it's no big deal.
So far, my wifi actually reconnects more reliably than on stock rooted 1.1. I'm overclocked to 1200 Mhz, with no voltage or other adjustments.
Following up again - I get a SOD or a reboot about every five times I turn off the screen in CM7. I tried to use Tasker to turn wifi off with the screen, which has solved the problem for some people but this made no difference at all. I was running a nightly from late July and updated to another from late August (173?) but the problem hasn't gone away. I may try Stock 1.2 rooted.

I had no SODs from almost a week with n165; I upgraded to n171, got an SOD first time I put it down for a while, so I reflashed n165 and I'm sticking with it until I hear of something I need.
WiFi always on.
As always, YMMV.

Just a little update:
Since using nb169, I got a few SoD, did update again to nb173, still got hit occasionally.
I never have this kind of issue before but lately.
The changes I made
a. Played around with ADW Launcher setting (especially Desktop Animation)
b. Recently installed Simi Clock and updated some apps (such Nook app)
c. Recently having 8GB uSD card plugged in.
For some reason, I don't think a. and b. causing problem but c.
can you run cm7 with the 1.2 or 1.3 updates from b&n? im on a autonooter 1.1 and have been wanting to move up to something better especially if i can have flash finally.

CM7 is custom Gingerbread-based ROM, it has nothing to do with stock ROM and there is absolutely no relationship between the two (except they are both Android OS)

thanks for the response
One last (I think) follow up. I installed stock rooted 1.2 thinking it CM7 causing me problems over the last month. Turns out I had the same problem on CM7.
I read my Nook before I go to sleep, so it's often dark in the room. I turn the brightness WAY down. The problem ended up being the Adjbrightness "Lock brightness so other applications can't change" setting. It has something to do with screen dimming when turning off the screen. This setting being on was causing frequent reboots both on CM7 and stock rooted 1.2. I ended up going to ScreenFilter instead, and the problem has completely gone away at least so far.

I try to stay up to date with the latest nightlies.
1) This is not completely solved. It's rare now (I think it was issues with WiFi), but it has still happened to me recently.
2) Battery drain was fixed with kernels that support Deep Sleep correctly. Not any 7.0.x builds, only 7.1.x+ (RC1) and nightlies have fixed kernel. So this shouldn't be an issue (unless you have a rogue app that is keeping the CPU active, which would prevent Deep Sleep. The "CPU Spy" app will let you see if this is working correctly).
3) This is better, but still a problem. My Nook Color will just switch off at 4% battery now. It use to switch off when I was a lot higher. It's not supposed to do that. It's supposed to gracefully shutdown when low. I have several iOS and Apple devices, so I'm use to things shutting down correctly when low. My Nook Color always just randomly powers off.
4) This isn't a big deal. The screen comes on when charging, but you can turn it off if you want. It stays dim, and the Nook Color charges fine. Dalingrin (the kernel developer guy) said leaving the screen on was a fix to some nasty crash.
#3 is the biggest issue to me, as I've been in the middle of something when my Nook Color randomly powered off. Clearing battery stats, rebooting, etc - none of that makes it perfect.
#1 use to be the biggest problem, but it's very rare for me now.
#2 has been fixed, and #4 doesn't bother me.

I misspoke; n165 SOD's on me too, so I conclude that I dl'd 165 and didn't flash it; I reflashed n161 and have been stable since.
I keep WiFi on for email and podcast updates.
I've always got an 8G uSD card in.

Nexus 4 switching off at night while charging

I know this has been discussed plenty of times but I just have some more questions of my own I'd like to ask.
So my N4 just switches off over night after being charged to like 95-100%.
It is usually fully charged (green LED) but won't turn on if I want to wake the screen.
I have to hold the power button for like 5 seconds for it to switch off. Then I am able to boot it again.
If i just unplug the charger, wait like 30s to a minute, the screen will wake, it works as usual. But the phone restarted (!!!) without any boot animation or anything. Just like nothing happened. If I then go into settings -> battery you can see the phone switched on just a minute ago.
This is happening like everynight for me now, so I had to use my old phone as an alarm clock as I slept in quite a few times actually
I searched like all forums and tried everything but I cannot dissolve this issue.
I even turned off deep sleep in dev options and stuff alike, monitored temperatures and stuff. Nothing conclusive though.
So I just have no idea why this keeps happening.
It happened with different roms and different kernels. Root or not rooted.
A friend of mine has a N4 as well and he does not have this problem at all. He does not have a custom rom flashed or anything.
But I read on other forums that even users with stock rom had this problems.
I think this is a quite common problem with the Nexus 4 device, isn't it?
Anyone solved it yet? Or does at least know the CAUSE for this?
I mean srsly there is like nothing on the forums..
Is it software related? Hardware related? Did I **** something up?
Is this a valid reason to send my phone back to google and get a new (working) one?
Everything else just works flawlessly. I mean the N4 with PA on it works so smooth like a charm.
I DO NOT WANT TO GIVE IT BACK!
noone? really?
I don't remember this being a common problem, though maybe I missed something.
If I was you I would wipe everything and re-flash stock. Then if it still happens return the phone, it shouldn't be doing that and I wouldn't put up with that if it was my phone. But it's your choice.

I have the same problem and I believe that this and similar issues are becoming increasingly mentioned on various sites on the net. XDA tread - http://forum.xda-developers.com/showthread.php?t=2077148 which gives some idea as to what people are doing to get to the bottom of the problem.
There is further info here - https://code.google.com/p/android/issues/detail?id=35139 which starts with Sleep of Death issues on JB4.1.1 (on the Galaxy Nexus but has more recently focused on the Nexus 4).
Initially the problem occurred maybe 3 times a week. I'm running a Stock N4 and whether stock or custom does not seem to make any difference.
I re-flashed a stock image and thought I had solved the problem. The phone ran okay for a few weeks and then reverted to random SOD's normally at night whilst charging. If I use airplane mode at night I have no problems. It has also become unresponsive/deep sleep on three occasions during the day. More recently I have stopped leaving wifi enabled unless I need it I no longer use airplane mode and have not had any further problems --- so far ---
For me at least, the problem might be wifi related.
This happened to me this morning. I have my phone on charge every night and it probably hits 100% about 3am every morning. I have the alarm set at 7am to wake me, and has done every morning since I got it last month. However I have now slept in twice (this morning was catastrophic) due to waking up to find my phone was switched off and my alarm subsequently didnt sound!! I have wifi left on, but all my apps are closed down, and only the alarm app running.
To switch it back on I have to hold the down the power button for in between 5-10 seconds for it to reboot.
Does anyone know why this is happening? The Nexus 4 is perfect in every other way, I'm gutted to find a fault after raving so much about it!
Same thing is happening to me every night !
I have the same problem, but it happens sporadically, so I never know when I'm going to end up sleeping in. It's infuriating.
It just happened again this morning. I had Wi-Fi disabled, so I know it has nothing to do with that.

Sounds like a rogue app is triggering the phone to crash or something?
Have you tried a factory reset?
This bs caused me to be late to a final exam... I was so mad when I woke up and saw that it was 2 hours later than the time my alarm was set to sound.. Only started happening with 4.4+ updates.

Charging cable
I have had this problem eventually with every android phone I've ever owned but it seems by replacing the charging cable with a new one the problem goes away. It seems that there is a weird thing with android where if the cable doesn't sit completely snug or straight the battery can charge but the phone won't realize this and go to sleep. Also seen the opposite happen where the phone thinks that the battery is charging and in fact it hasn't. When you unplug it suddenly goes from full charge to nothing. Haven't seen that last one on my Nexus 4 yet though. So I would try replacing the cable (not necessarily the charger) usually worked for me on other phones. Also I would suggest not to leave the phone and cable hanging off the end of a table. Make sure it's in enough that it sits flat. I think this is how I slightly bent mine.

[Q] Wakelock/Sleep of death (charging and not charging)

My phone has always had this problem, but since Kitkat it seems to be happening more frequently.
It happens when
1. Phone is on charge over night
2. When the phone sits idle for a long period of time.
I've tried several roms/kernels but the problem always persists, I had a nosey around but couldn't find anything in specifics. I tried an that solves the problem when it is on charge well it seems to work it happened a lot less but still happened.
What causes this?
Are there any solid fixes?

making the lower CPU frequency a little higher solves the issue. i've been having this exact same thing.
so instead of setting the minimum CPU freq to 384000, make it a little higher, maybe 486000 or 594000...

Hi, did you manage to fix this by raising the minimum CPU speed? I have the same issue on KitKat 4.4.2
I suspected it could be an app (possibly G+ which is known to drain the battery). Others have suggested it is to do with the wifi policy and the phone locking when the wifi disconnects or reconnects. I am use CATACLYSM ROM now and it seems more prevalent on this than it was on Stock, so I may simply switch back and monitor. Cheers.

moto g4 random shutting down

I have found a lot of complains about moto g4 (plus) random shut down and with solution at lenovo forum.
I am wondering any one have any solution here.
My G4 got the same issue recently. I am using stock rom.
Me also experienced same. The problem might be for overheating. I switched to linage os to get rid of but it still restarts very often..
thanks for reply. I will not waste my time to change ROM then.
I will try to change a new battery see if it works. I will report result next week.

My wife's phone has just started doing this too. It seems battery related as when it shuts down it does it instantly, but seems stable when it is charged fully. I think when the battery is reporting about 20-30% full charge through the UI, somewhere in the background it is getting the message that the battery is empty. Might have to try a new battery to sort it.

I was initially happy with this phone and bought this same one for my wife and my father-in-law. Then mine started shutting down randomly, and after a while the two other phones, too.
The behaviour is not completely identical; mine almost every time shuts down when in a video call. The others seem to shut down when receiving phone calls, perhaps combined with low battery charge.
Have anyone had any luck with a battery change?
