Unknown issue with auto-shutdown on Galaxy note GT N7000!

[RubenLockheart]

Hello everyone!
I have recently purchased a galaxy note, and since then have had a constant problem of auto shutdown, at the beginning it happened once or twice so I didn't even mind, but now its just becoming too frequent for the phone to even be usable!
I can't return the note, and have no warranty (nor money to buy another one). Son no viable solution there.
I sold my previous phone so I could buy the Note, without it I am phoneless.
I have looked EVERYWHERE for a solution and haven't come to one single conclusion yet!

I will now post some facts about the phone's situation:


Model GT N7000
Rooted: yes, via cwm
Rom: Jelly Bean 4.1.2 Beta, flashed via cwm (but the issue occurred on stock ICS, gingerbread and costom ROMs too, stock ROMs where flashed via PC ODIN and mobile ODIN)
Kernel: Phillz flashed via cwm

-Does not shut down while connected to charger (and is charging).
-Tried different kernels and ROMs, official and custom ones, and the bug kept happening.
-Shutdowns are completely random (although I found that using ROM Toolbox and setting CPU min to 500 and governor to Performance the phone became more stable and didn't shutdown so frequently. Recently these last 3 days this has become pointless, the phone is unusable unless connected to charger)
-Auto shutdowns happen when phone is in sleep, or awake, no matter what I am doing with it, it just happens.



I am thinking of replacing the battery, since no matter what software changes I do it keeps shutting down maybe a new battery will help.
But then again, I don't know, I'm just desperate...


Thank you for all those who take the time to read this!

Interesting, maybe the logs show something. Check logcat app for that. Elixer2 has a good overviewable one. There might be some hints shown as to what is happening. I cant really help you with interpreting.

Do you do clean installs? mind the brickbug
Battery levels, they show correct values? Also after reboot same value as before? You can set in settings, display I think battery tp percent. Easier monitoring from statusbar.
Try andrometer to check voltage levels as wel. Fully charged should be around 4200 mv.
Do a little dance to brighten up your mood.
Next, or first, check if battery contacts are clean and alligned when putting battery in. It might just be a loose fitting. I doubt that thought.

With autoshutdown, you seen android saying, shutting down now, or does it go black and just crashes so to speak?

Thank you so much for the help!
I have been suggested to purchase another battery, and had actually been thinking about that!
Will andrometer confirm my suspicions that it is a battery issue?
The battery connectors are clean, cleaned them when this problem first appeared.
And the shutdown is as if I suddenly removed the battery, the power is cut right off the device.

I cant dance but I'll play guitar, that always helps me, thank you for the suggestion! xD

hum, not software related imo, really an hardware issue, electrical issue, related to battery as it does not occur while charged.

first of all: easily done: remove any SD card and try. still the Pb?
then borrow another battery, fully charged, and try. Still the PB?
then with your own battery again (as it does not come from the battery), check the electrical contacts (dirty, embossed...), try to check that mechanically the battery is firmly kept in place, add sticky tape/pieces of paper to maintain the battery. Still the PB?

then i am afraid that the best to do is going to... after sale service... it may be only a small welding a bit cracked on the power circuit, sometimes a small vibration or a temperature difference opens the power line and your phone immediately shut down. It is almost impossible to locate and to fix for common people.

good luck mate !

Side note: setting CPU min to 500 and then setting governor to Performance is pointless, because performance = always max CPU frequency.

Anyway, I can think of various ways of checking whether your CPU is misbehaving at some frequencies (like SetCPU stress tests on different freqs set to both min and max) but that's likely not the case, all signs do point to some kind of battery issue.

If I were you, I'd try to find a battery somewhere (friend/relative/whoever else with GNote, or even a shop) and see if the problem persists with another battery. If it disappears = buy a new battery, whether official or copy or bigger size, whatever. If it persists = at least try to flash some more customizable rom/kernel combination, of ICS kind - where you can over/under-clock/volt.

Thank you saturax555 and GwynBleidd for your suggestions!
Unfortunatlly I dont know anyone close to me that has got a Gnote, but I will buy the battery and test it out, its not expensive at all, I've seen a 2600 (Or 2400, can't quite remember) mha battery for salle somewhere, if it fixes the issue I'll even end up with a larger battery!

I'll inform you guys of the results after I get a new battery, so if anyone else has the same problem we can help them too

+1 on all above comments. It does appear battery/ hardware issue. Lets hope a new battery fixes it.

Andrometer will only confirm if charging level is reached. Also you can use it to check if at certain voltage this occures. It gives false positive on good health battery.So thats not a thorough indicator.

Guitar is way cooler btw :thumbup:

I searched for andrometer and all I got was an app to measure distance using GPS :s
So I got battery spy today and these are the results so far (See image).

My voltage is usually around 3900mV and 4300mV, usually at 4192mV, can anyone say if these values are normal??

Appears normal. Battery appears charged. app is called androsensor, mixed them up.

Do you get weird artifacts prior to fallout? Like screen flickering, lines and such?

Am so interested in cracking this nut.

You could check emmc brickbug app. You will have bug as all notes, but it also does a sector check. Like if part of emmc is corrupted. Am not expecting this to be case as clearly its battery related. Just want to be sure.

No flickering or anything, it's just like if I suddenly removed the battery.

Got new results from emmc check and I downloaded andrometer


Thank you so much for your help!

 

[baz77]

Cool.

I have a hunch its not battery, cause unstable battery usually(not 100% sure about symptoms) has those flickering issues.

Its not emmc, test passed yes!

you had it on different roms. With clean installs and different modems, kernels, etc. No common denominator romwise. maybe app or hardware.

Then its interesting to keep both cpu temp and battery temp in check. See if there are spikes prior to fallout. cpu temp I am not sure. you can try cooltool, disable gauges and setup cpu utilization, frequency, ram size, battery % and temperature.

watch those values for abnormalities when it occurs.

Also check the logs for errors/warnings (elixer2 has a good one)


But I am at a point of really guessing. I have a feeling its hardware but am hoping now for rogue app or battery still.

maybe someone else has some ideas.

Hey guys! My new battery just arrived and I just plugged it into my note and it is back to normal!
It's an official galaxy note replacement battery, 2600mah (100 more then the original, not much of a difference I know) and it was relatively cheap, 15 euros and I even had it delivered to my house!

I want to thank you guys for all your help and advices!
Thank you all from the heart! You contributed to making me a lot happier today!!

Best wishes for all of you, (dare I call you) my friends!
Thank you!

I had this same issue.. Mine was bought last year.. Just around 2 weeks ago i want to root and put a custom Rom...
I root using cf-root + philz kernel.. Then i flash rocketrom 4.1.2... V3 i think.. Then this issue came.... It 's does have flickering issue before it' s going off.. This all thing doesn't happen while on charge... I'm still not try using others battery..... I also have flash others custom Rom.. Like Ultimate, fusion.... And lastly i unroot it using stock fw at sammobile.. Still it's happen

 

[RubenLockheart]

Try changing the battery, that fixed my note right up!
Is the symptoms are the same as mine its not software related, order a new battery, and if you want you can root and flash the rom that you want so when it arrives your note is ready to go!

Tip: root the note and get battery calibration from the play store, it's free, you will need it to recalibrate your new battery so you get real values displayed and to avoid excessive battery drain.

I'm facing the same problem and its getting frustrating. I'm currently using Asylum ROM 20130303 build and latest Gapps for android 4.2. did a full wipe. tried checking my battery stats and its normal. did a recovery, flashed again but still problem. my gnote just shutdown and cant turn back on unless i plug the charger. any help?

 

[nokiamodeln91]

may be you first need to try with an alternate battery first.. or go back to a stock rom and test.. most prominent symptom is using the camera with flash shuts down the phone immediately

 

[flame_jet]

i purchased a new battery and now its running fine

 

[swaldrop]

The phone is flawed and shuts off on it's own under various conditions, all hardware related. I am not able to post externally due to not having enough posts yet. However, I have had the same issue on 3 Galaxy Note 2's from Verizon. I made a video that shows exactly what is going on and posted it on the following website...

wwwDOTgalaxynote2shutsoffDOTcom

You will have to paste that link in to a new browser and replace the DOTs accordingly to get to it, but once you see the video, you will be enlightened. Be sure to read the details I provided on that site as well. They go in to detail about the problems that I have had and the lack of proper support that Samsung is willing to provide.

 

[Satesh]

Same issue

may be you first need to try with an alternate battery first.. or go back to a stock rom and test.. most prominent symptom is using the camera with flash shuts down the phone immediately

I seem to have the same issue

1. Battery drains rather bad
2. Screen flickering
3. Auto shutdowm

Used the battery in my wifes n7000 , however no issues at all
Only seem to happen on my phone.
I flashed it to stock std 4.1.2 , however problem still persist. auto shutdown few times a day
Gets worse when i use an external SD
