Note 2 shut down - Galaxy Note II Q&A, Help & Troubleshooting

I upgraded my note 2 to 4.4.2 KitKat. I discovered a mysterious behaviour. Whenever I try to shutdown the mobile phone, it just restarts. Have tried this 6 times but it restarts. Also, battery shows weird percentages.
On 1 occasion it showed 20% charging. Immediately on restart it showed 56%. I am amazed. Can't get my head around it.
Kindly help.

[Q] Reboot problem when not charging

I have had my P607T for a couple of months now. It is box stock no changes. Over the last few weeks I have noticed that it will reboot while using various apps. (Fliipboard, Chrome, Clash of Clans, Papyrus...) They don't seem to all be heavy graphics or network. The only symptom is that the screen starts to flash then "bang" reboot (and trouble rebooting when not plugged in). It would not be too annoying except that it will loose wifi settings and the wallpaper. I have tried different wallpapers (saw a thread blaming the live wallpapers ) Unloaded some apps (had another phone issue with FitBit and HTC blink on my N4). I stay away from CoC (my base has been raided so often now ...). Any thoughts? I am really trying to like this tablet more than my old ASUS Transformer but this reboot and reset wifi is a pain.
Thanks in Advance,
marka

Have you tried a factory reset? I'd make tmobile replace it
was hoping to avoid the reset button. Tried it and still giving trouble it rebooted while restoring apps. I bought the tablet on ebay, I don't think TMO will take it back. oh well I'll keep poking about.
thanks,
I experience exactly the same problem since the update to 4.4.2 (kitkat): The screen starts to flash, suddenly the tablet reboots. I tried a factory reset multiple times, also removed the SD card and reflashed the ROM via KIES, nothing helped so far. Also, even when plugged into the outlet for several hours the tablet didn't charge at all (I think it stopped charging when the screen saver kicks in).
A couple of weeks ago I filed a RMA request (my dealer sent the tablet to Samsung), yesterday I got it back. It was charged at 60% and when I plugged it to the outlet it actually charged (even when the screen went off). But after about one hour (the battery was still > 60%) the flashing reappeared and after a while the tablet started to reboot again. Interestingly the battery now showed only 2% and the low battery warning appeared.
I think the problem might occur only when the battery runs low (which happens very fast as something seems to drain the battery), while android still shows a much higher battery level . Never experienced these problems when the tablet was plugged in so far.

At least I don't feel so alone with this issue... I have been paying more attention to my build up process since the factory reset. I found, the other night quite by accident, that when I logged in to Twitter the reboot started. So for the next few days I have left Twitter off the machine and it is doing better. I suspect that something is hitting the power drain (like you mention) and that causes it to have problems. In that thought I have also turned off the power saving mode and auto screen now just to add to the list of things I am avoiding.

Have you considered rooting and using root apps to stop the apps from being able to do such things?

TAB S 8.4" Very Very Weird Problem need help

So my TAB S is a few months old like 3 months now
I only installed few top rated APPS and everything is working fine, i use it to facebook and youtube and reading and some emails, i rarely game on it
2 days ago something very weird started to happen when battery reached 30% the device slowed down and froze up and rebooted on it's own, when it boots up , it forgets the wifi password, and the battery is like 15%
freezes up again after 30 seconds of using , and again reboots, forgets wifi password, battery level is 10% , a minute later same thing battery like 4% HOWEVER
IF I TURN IT OFF ,AND PLUGGED IN THE CHARGER IT SAYS 29% AND CHARGING.... so the battery level from within the OS is not true and it freezes and reboots and upon that forgets the password of the wifi
I DID NOT ROOT IT , I TAKE VERY GOOD CARE OF IT
now i tried draining the battery all the to 1% and 0% then full charge , and it wroks untill it reaches 30% - 25% then problem all over
if i plug it in the charger and use it , it seems fine
what could be the problem and do i have to factory reset?

Battery problem

When I charge my battery and it is 100% my TAb S is switching off. I only see the battery picture showing 100%.
I did a hard reset and a clear install without results. Anyone an idea what happens?
Are you saying it switches off completely or the screen does?
It switches off completely, not only the screen.
I had this problem a couple of weeks ago,has soon has the tablet booted up it would switch off then I would have to boot up again,then it would switch of again.i had the battery changed by Samsung about a month ago it started switching off since that battery change,the new battery started discharging just like the first battery,the tablet is now back with Samsung,i am hoping to get it back in the next couple of days,lets hope they fix it this time.Longlegs

Battery Level stuck @80%?

I can not seem to clear my Issue of the battery always showing 80%.
I have reflashed back to Stock, but still the same problem.
Even when I had TWRP recovery installed it showed as 80%.
Any ideas how to fix this please?
you have infinite battery, be happy!
I wish
Fixed it by flashing Open EU H815.kdz file once again and now the battery use is showing correctly.
Edit: The problem is back again!!!!
After several hours when it seemed okay, I put the phone back on charge and Bingo.
Stuck back at 80% again, even on my other original LG Battery, and to top it all i have a stuck LED on faint green.
WTF???
I had the same problem before, how many apps do you have installed? Does it charge in safe mode? If not, does it charge to 100% when the phone is powered off?
Tried Safe Mode and the same problem persists.
The battery seems to charge fully but the OS is not showing it correctly
Hmm, in my case, it was always stuck at 74%/75% and it doesn't charge more regardless what the indicator says. What about if you powered off the phone and charge, does it actually go past 80% and to 100%? I fixed my problem as I had 739 apps installed incuding system apps so I greenified everything except for those I needed and that fixed the problem, not only am I getting more than 2 hours of battery life regardless if the screen was on or not, it's now 12 hours or so of battery life with a few hours of screen time but the charging is fixed. Before I used to also have problems installing in Google Play Store, it would actually sit there doing nothing after the download and install when it feels like it even after a hour or it can install fast.
Tried charging while turned off and still gives the same reading.
Last night I reset the phone and left the battery out for 30 mins before re-inserting and setting up the phone once again.
So far it seems to be fixed and showing correct battery %.

Sure, see attached.... Please note that I am including the system apps in the app count as this is what's reported by Titanium Backup *root. I was wrong, I seem to still be getting the stuck battery percentage indicator which can happen at 73/74% or even 97%.
It seems the stuck battery charging % problem came back when I changed the brightness to 100% Auto but went away when I changed it to 0% Auto. I had the problem at 38% Auto too.
Is there any workaround? I just flashed my LG G4 from 10a to 10e and Rooted it. And It happened exact the same.
After a reboot I didn't have Service IMEI Null . This happened twice in a row, after that it magically resolved and now I have Service and IMEI... But after some reboots I started noticing that LED green turned on and the 80% Stuck Battery....
Im experiencing the same issue battery stuck at 80% and green led stuck on. Issue went away however battery life was appallingly bad, went from 1.5 days battery life to struggling to last a day. Battery stuck at 80% has come back today.
I have tried factory reset, upgrading from 10c to 10e.
i'm having the same problem: battery level stuck at 80%, network set to 3G but not actually connecting, and the inability to charge the battery when it is in the phone - even though it says "charging" the percentage kept dropping (tried different chargers, cables, batteries, and even wireless charger - i can only charge using a separate charger). the battery not charging started about a week ago. the 80%/3G issue started this morning.
no root or any other mods, very few apps installed. i've had the phone about 6 months. verizon. 13B. 5.1.
i did wake up the other day to a frozen "firmware update" screen, but it has not come back, and i've checked for updates (to 6.0 maybe) with no success. this "firmware" screen was after the battery stopped charging, but before the 80% problem. i had to pull the battery after it sat there a few hours (it said "don't disconnect USB" even though USB was never connected, and there was a progress bar at 0%).
UPDATE: this thing may be falling apart in front of my eyes. now my service is disabled and I have no network connection showing up at all.

Try taking the SD card out, if that doesn't work take the sim card out and then back in. That normally gets the service working again for me.
I had this same issue and sent it back to the supplier, they than forwarded it onto LG who couldn't find any issue with it. Im now waiting for it to be sent back to me.
Are you using a 3rd party (non-OEM) battery by any chance? I ask because I had the same issue occasionally when using a non-LG battery. It would fix itself after a few reboots or by installing the LG battery that came with the phone. I truly believe based on my experience, and others (there is another thread related to this exact problem) that the issue is purely battery related. Even the service disabled symptom.

I don't have a 3rd party battery so I don't think that's my issue
OEM battery for me. I did remove SD card, and reseated the SIM: no help.
This is my current work around: Turn off phone. Charge battery to 100% with phone off (overnight). Turn phone on.
It seems to charge fine (and have accurate %) when the phone is off. Then it powers up with accurate battery percentage and 4G coverage. Note, I've only tried this twice, but it worked both times.
I'm having the same issue. Battery stuck at 80% and green constant notification light. Not rooted BTW.
I assume LG will investigate the issue while I am stuck with no phone for weeks.
I should have never bought a non nexus phone...

Phone turns off when unplugged from charger.

After charging phone to 100 it will only work for short time and then it will randomly shuts down (usually the moment u use it, like unlocking the screen or getting a call). And then it wont turn on until u start charging. Sometimes when u plug it back in battery is at ~90%, sometimes it goes back to 0. I was thinking it was battery's fault but almost every time this happens my phone does some kind of soft reset, sometimes my themes reset back to stock, sometimes my saved wifi dissapear, notification settings reset, etc. Phone has the screen replaced a year ago too if that could add to it.
You can try to revert it to stock, but most probably is a battery problem.
I've been using my phone for 3 years already and a half year ago I noticed that id didn't hold a charge when the battery went below 30 % . it randomly shut down below 30 % epsecially when I tried to take photos or use flash (that require high Amperage) . Sometimes it restarted itself after unexpected shut down and as I noticed dalvik cache was formatted/deleted. so I had to login to my google account set themes and etc. after I upgradet to 7.0 every unexpected shut down began to worry me becaouse even app data began to dissapear. So a week ago I ordered a new battery and now I am relieved . in my opinion it's 100% battery problem .
Definitely a dead battery. 3 years is a long time for these batteries. You did well to get that long from it!.
Thank you for this thread. I was starting to go loopy because I thought it may have been some app. Same issue and I need to find a battery guy.
