[HELP] Critical CPU glitch - Galaxy Note 3 Q&A, Help & Troubleshooting

Model: SM-N9005
Country: Unknown
Version: Android 4.3
Product Code: XSI
PDA: N9005XXUBMJ1 (previously N9005XXUBMI7)
CSC: N9005OJVBMI2
MODEM: N9005XXUBMJ1 (previously N9005XXUBMI6)
There is CPU-related glitch that I've experienced since I've bought the phone on the 25th of Sept.The bug existed in the out-of-the-box firmware as well as in the new MJ1 firmware. The reason I didn't bring this to light and seek advice earlier was because I wanted to wait for the first firmware update (which came) hoping that it would be fixed (which it wasn't).
Description of the glitch: The processor would go on a state where it would ONLY start utilizing CPU1,CPU2 and CPU3&4 would remain "offline" no matter how much stress is placed on the phone.
Symptoms: I can clearly see the phone is only utilizing two cores with any CPU monitor from the market (see screenshots below); phone gets hot much easier under heavy stress as all stress is being put on two cores instead of shared between four; benchmark scores drop by half (example: quadrant score is ~21,000-22,000 , it drops to ~12,000-13,000 once the processer goes into that state); some demanding games start to exhibit lag and choppiness.
How frequently does the processor go into this state: It sometimes happen once in a day. Sometimes it happens once in 2-3 days. As far as I know, it remains in this state unless and until I reboot the phone. I don't know how it's triggered.
How to temporarily resolve the problem: The only fix I came up with is to reboot the phone, whereby the issue disappears immediately once the phone boots up again (that is, until it comes back again in a couple of days).
Is the problem software related? Does the problem exist in other Note 3 firmware?: I'm betting it is a firmware rather than a hardware related issue, otherwise the problem would not go away with a simple reboot. I don't know if the issue exists in firmware other than mine. It's probably not wide-spread, since I haven't seen it reported by anyone else. This is the reason I created this thread, to bring awareness to other people as well as to hopefully get help from someone more knowledgeable about this kind of thing on how to go about to get rid of this issue (the temporary fix is easy enough, but I don't want to bother with rebooting my phone every other day for one year.)
Could some root application be causing this?: Nope. The issue occurred before rooting or modifying the phone in any way, it's still present now that I have rooted it.
Other things to note, power saving is OFF always. I never turn it on. I don't have any application that could restrict, under-clock or otherwise modify how the phone or processor operate in any way.
I have attached screenshots below of when the processor is operating normally, and when the processor goes into the utilizing-only-two-cores state.
Applications used: Stability tester [to put stress on the processor], System Monitor [..to monitor the CPU, obviously]

Do you have to leave the monitors running many hours to catch this issue or does it occur quickly after reboot?

It happens so randomly and sporadically. I can go for 3 straight days without reboot and without the problem happening. I don't keep flying cpu monitors active all the time, I just opened them for the sake of taking the screen shots.

I had just noticed this on my exynos note 3 today, at least it may have been the same issue im not sure yet. For the second half of the day the touchwiz interface and several apps were noticeably laggy, not a huge deal but compared to what it should be. It was working at about the speed you expect from a midrange phone. Nothing special was running, I cleared all apps from memory but it made no difference. I restarted and it has gone, but if it happens again i will be sure to check how many/which cpu cores are running. I have rooted it but no other modifications.
Come to think of it chrome was lagging like a ***** all of a sudden the other night too... I was tired and went to bed without investigating further though. Perhaps that was the same thing as today, which could be the same thing you have...

I can't see your phone so I don't know what is exactly going on, but if you type into Google any smartphone name and word "overheating" you will see dozens of threads and articles. People are just overreacting, smartphones are getting warm it's just their nature, plenty of processing power etc. If yours is getting too hot maybe it's some app working in background.
My phone gets very hot on top of screen, near speaker

My phone is also overheating very quickly now. It started after i rooted the phone and installed some root apps like greenify and clean master. I have now disabled those apps to see if it helps.
Anyhow, it's not a big deal. It won't burn up so what is all the fuss about?
I have the same thing, the same spot as you mention. On samsung stock rom its really worse!, but on cm its decent. however, my pone always turns off when testing antutu at stock max cpu speed...
I can only go to 1674mhz. any higher and it will instant shutdown on antutu
hi, i'm from singapore
and im using the i9505 variant of the S4 and i'm having the same issue about the heat on the top half of the phone
it heats up so bad i cant touch the top half of the phone at all
Is this caused by the 4.2.2 update like what everyone says?
My view/experience with i9505 on (over)heating. I direct this at Samsung ...
Dear Samsung,
Please can you move the WiFi Power Save Mode Toggle from the Service Menu and place it in the standard Settings Menus. Also make this setting persistent between boots.
On certain AP hardware and/or configurations, the Power Save Mode does no saving at all, in fact in my experience it just causes a huge mess. The culprit is spotty/erratic WiFi connectivity which causes all the background sync/update tasks to go in retry loop heaven (with wakelocks galore). These background tasks in retry loops hammer the processor continuously such that it start heating up (& draining more battery than normal).
So please implement this small change so that it can save many a lot of headaches.
Thanks.

Heating is a big deal for me. S4 is a lot more hotter then my former S3, and not because of the CPU. For me it's because of the modem. Root might be related also (I had my doubts on this) ... some apps keeping the 3G up more then needed, but I don't want to speculate more ...
PS: there are others "overheating" posts , a lot of them.
Same issue here (thread here), my brother has the same model and we tryed use same apps on both S4's, his S4 does not heat but mine does. so something wrong with my S4
i think the rom is causing all the overheating issue.
when i used stock, it would heat up that i can't touch it
now using phoenix rom 2.0 for 9500, and only get a slight warmth
My first smart phone was an Galaxy S2, and it got hot, i had two replacements they were the same, i then realized smart phones with powerful cpu/gpu`s just get hot when they work hard, i had had a few smartphones since the S2 from a few different manufactures and they all get hot, now i have an htc one, and it gets hot so it`s totally normal.
what i have realized with android is that you can get a faulty app or system process that really kills the cpu/gpu for no reason and they need to be shutdown/killed.
So i started using an app called watchdog, just change the settings to monitor system processes as well.

my friend is using i9505 as well and his doesnt heat up like mine does
when i bring it over to Samsung, they said 'its normal'
and they said nothing can be done about it
My phone was overheating as well, and I found out the culprit was media server. It got confused with some old thumbnails I had on my old SD card (from my galaxy S3), I had thousands of pictures there, so I guess it was constantly scanning it.
So delete all the thumbnails, (there's a folder .thumbnails in DCIM I believe) or even better yet, if you can, format your external SD card, and copy the files you need on it again. then mediaserver will work hard one more time and that's it.
Alternatively, you can download Rescan Media ROOT, and disable the media scanner, and enable it when you need it (but that's not desirable for me, I'm always updating my media, so I prefer it being automatic, depends on you usage)

The S4 does heat up quite often, what version you using? I would recommend to use KT kernel to underclock and undervolt so it doesn't heat up as much
Ow i like the heating part on my SG4 its really helpfull if ill ever go to Antarctic
Its a life companion.

[Q] Galaxy Note 3 Gets Hot

Since taking the Verizon over-the-air update to Android 4.4 Kit Kat I have noticed it gets hot - not a problem prior to the update. I notice it while playing SlotoMania, watching videos on MX Player or just browsing Facebook posts. These apps are not new and my phone didn't overheat prior to the update.
Has anyone else experienced this?
There is more to this than meets the eye. I am on NC2 leak and suffer from this issue. What I have noticed is when the phone gets extremely hot it starts to drain battery VERY fast as well. I mean 10% in a about a min. It also becomes very unresponsive and laggy. I have to shutdown and do a battery pull and everything comes back to normal. I feel like there is a specific app or even that triggers it but can't quite narrow it down. It happens about once or twice a day for me. It is very annoying never happened before getting on NC2. I'm hoping once we get find a way to upgrade to NC4 this will go away.
EDIT: I just noticed you are not on NC2 and took the OTA. I am experiencing this on NC2 so this give me no hope in NC4. Maybe a reflash or factory reset might do the trick.

This has happened to me and I unfreeze everything in tibu except the VZW bloat and I have yet to have this happen battery is still good ram still good and everything is fine no more slow down no more heating I keep my phone with Bluetooth on and the gear watch and still getting over 3 hours screen time awesome

Im in this boat... Tried all the NC2 roms available and always the same. Works for a while fine but then all 4 CPUs continuously run over 50% (I can see this in Hyperdrive Rom) until I reboot. Tried killing apps, freeing memory, going into airplane mode, turning off GPS and nothing affects it. Like if its a kernel memory crash happening. Screen will be come unresponsive every 3-4 seconds yet background animations like livewallpaper keep running. In Battery it shows that the google services is eating the battery.
I have flashed back to 4.3 about 3 times now and I am always successful in getting the phone to work normally on 4.3 but no 4.4 NC2 rom agrees with my hardware. Ive even tried the MJE Radio as I thought it may have something to do with it as whenever I use my phone on NC2, it gets hot and cools down after .. Phone doesn't even warm up on 4.3 As more people experience this with NC4/NC2 hopefully someone will find the cause..
I will flash back to 4.3 sometime soon as the phone getting soo hot with normal usage is uncomfortable..

I'm with you in that I feel like its a kernal issue. I'm just surprised more people have not come into light with this issue but I guess Kitkat is very fresh to the general public.

Or those of us like myself hated the worse reception we got and ODIN'ed back to MJE. I got 0 signal where I usually got 2 bars and 3G where I always had LTE. MJE ftw. I guess that's why they came out with NC4 so quickly?
that's ..
if u installed Wanam xposed,
go to advanced, and turn off the touchwiz DVFS.
what it does is that it boosts the cpu and all, to pull the maximum performance, but only for very short term, as I hear.
also, I checked it off, and never had heat issues other than me rebooting about 7 times in a row.
Alright this is going to sounds silly but I live in an area where my service sucks. Actually every carrier does (best friends were in town and both had att and sprint iPhone and had worse service than me) I also use a network extender. So today I decided to turn band 4 off since I'm not in a band 4 area and not only am I at 4 hours screen time today but I'm still at 36 percent and no hot phone. I'll report of anything changes

[Q] Question about rooting my Note 3 for better battery life

I've had an AT&T Note 3 since January. The phone is great but since the update to 4.4.2 I have been experience horrendous battery life, to the point that I'm having to charge it throughout the day.
I work construction and use my phone for several hours per day, resulting in 2-3 hours of voice calls and 2-3 hours of screen time. My last Note 2 and the current Note 3 used to be able to handle my workload while being unplugged from 7AM to 10PM at night.
If I was to root my phone, could I gain back my battery life? I have never had the need for my phone to be anything other than stock but I am desperate at this point.
Thanks
Rooting your phone will not result in having better battery life. What you can do is detect apps that keep your phone awake. Another method is to flash a custom kernel with lower voltage or one on which you can undervolt yourself. Be aware that by rooting and/or flashing custom recoverys/kernels or firmwares you'll trigger the Knox counter. This will void your warranty. There is no way to revert it.
Please use the Q&A section next time you have a question. Hope I could help you a little.

I appreciate the reply. I was hoping that rooting would allow the phone to run off of custom firmware and not have the horrible battery drain many Note 3 users are experiencing after the 4.4.2 update.
I have installed GSam Battery Monitor for over a month and been monitoring it daily. I'm consistently seeing Android System and Kernel (Android OS) using 40% of my daily battery life and Media using another 15%-25%. Other than that I've been unable to determine much else. I do not play games or Facebook, I just talk and text all day.
Is the warranty on the phone one year? If so, I'm 2/3 through it and would be willing to void it for better battery life.
I have looked through all I could find before posting, but honestly am somewhat overwhelmed by all the information on XDA. This is magnified by the fact that there are many versions of the Note 3 and different carriers.
I have a N900A Note 3 and am looking to get my all day battery life back and appreciate the help.

Don't worry, it's normal to suffer infoglut the first time looking through xda. You'll get used to it =)
So you have the AT&T version of the Note III aka hlteatt or SM-N900A. You're device has a Qualcomm chip built in like most of the Note III variants out there. There's also a Note III variant which has an Exynos chip built in but I think you won't confuse Exynos firmwares with those dedicated for Qualcomm variants. The ROM threads ususally have pretty good descriptions about that. AFAIK most custom ROMs are compatible with any Qualcomm variant. E.G. any AOSP/CM ROM for the Qualcomm Note III has a unified build carried by the name "hlte". Meaning, that as long as you don't flash an image meant for the Exynos variant, you should be good.
40% for Android-System and Kernel isn't normal at all. I also use GSam Battery Monitor. Android-System and Kernel only use about 19% of the battery on my phone. Something that helped me when I had the exact same issue was to switch locating method from high accuracy to power saving. You can find this setting by long-pressing the GPS icon in the notification drawer. The location settings menue will pop up. Under "Mode" you can change to "Power saving". I'd be happy if you could report if it did work for you.
You're welcome =) Just hit the thanks button.
If I may add my own comments here:
1. you should go to note 3 ATT forum and there find proper method to root your phone, we have towelroot program that can root phone very easily without breaking knox warranty, albeit I don't know if it works on your version, it worked perfectly on mine (t-mo)
2. While it is true that root by itself won't do anything about your battery usage, many programs that really help need root
For example greenify, titanium backup or android assistant require root to disable many useless (useless for you that is) programs that drain your battery
3. I totally disagree with Nitrous that GPS is the culprit for high battery usage. It is my experience that GPS all by itself does not work at all unless the location info is requested by some other programs. Google maps for example only run GPS when screen is on, when screen is off, GPS is off also. However some badly behaving programs can keep requesting location even in the middle of night, but IMO those programs are the problem, not GPS itself. I have GPS, BT and WiFi on 24/7 and with light use my phone could last 4-5 days. If GPS was draining battery as many people think, phone would never last that long.
What you should do is go to ATT forum and find towelroot method, root your phone and freeze, or disable apps you don't use. For example I don't use Bloomberg, Yahoo, Facebook, Hangouts, indexing etc (your list may be different, since different provider) so I have them frozen (won't start up) . If I ever change my mind, I can unfreeze them later.
You can also run programs to tell you which apps use most battery, or wake the phone from sleep and then decide if you need them or not.
BTW sometimes full reset and cache clear can fix some of the problems, so maybe that should be the first step.
Once you find which program /s cause problems your phone should last whole day. I could easily get 6 or more screen hours on my Note3, unless playing some intensive games, so should you and it just took couple hours to identify and disable all the bloat and there is a lot.
I also experienced increase in battery usage after updating to KK, but I have not found a time to look over the bloat and redo my program freezing efforts yet.
I know that GPS doesn't drain battery that much. But trust me, it is very likely to cause that type of behavior. I'm in this forums since a couple of years. In most cases, when Android-system and Kernel drain unusual amounts of battery it was location services that was causing it. But not because they were using GPS, but because they kept the device awake the whole time. And there you see my point of switching locating methods. In 90% of the scenarios where people described this kind of behavior of their devices, this solved the problem. But you're right in saying that it's not a permanent solution. I agree to your first two points.

I always have GPS off and only turn it on when I need it though Android still has the higher or second highest battery usage.
I agree, root and uninstall /freeze bloatware. You'll be surprised.

Just to give quick update, after I wrote my comments here, I fully charged my phone and went to sleep. In the morning battery was down to 80% and that finally prompted me to action. I freezed some apps, cleared cache and did some "housekeeping". I don't know what did the trick, but this time overnight my phone went from 100 to 98%, 10 times better than a night before. Now, after 18 hours of some light use like few calls, couple games, light internet use etc it is still at 80%, so it's pretty much back to what I had before update. I wish I wrote down what I did to track particular culprit in my case, but it is amazing how couple bad apps can ruin battery life, but at the same time killing them turns things around so much. All in all, out of some 340 apps and services on my phone, only 21 are frozen and about 30 are stopped from starting at boot up, but are able to start later if needed.

Last question; 340 apps system-wide, or 340 PlayStore apps?

[Q] Does the S4 overheat?

I currently own A TMO Samsung Galaxy S3. I am thinking of moving to the international version of the Samsung Galaxy S4 however I am not completely satisfied with the S3. Mine overheat, slows down, and reboots sometimes when pushed hard. It pulls so much power while in the car that navigating will drain the battery even with the car adapter. So is the S4 any better?
The S4 can also overheat, though I've not encountered problems with heat.
You have a TMo S3. If you are in the US be aware that in the US the I9505's LTE will not function due to not having the correct bands. Best you'll do is HSPA+. You may instead want to consider a SGH-M919, the TMo S4.
I have the international version of the s4. It does get quite hot at times. Especially when charging and gaming at the same time (not hardcore games, casual puzzle games like Flow).
I don't want to know what happens if I really take it to it's limit
Anyway, so far I haven't had any reboots or slowdowns because of the heat.
I will be moving to Europe which is why I'll want an international phone.
I did google this question and there are complaints out there, just wondering if the problem was fixed with a software update.
Thank you for the replies so far.
I have mine on Android 4.4.2 and haven't had a single moment of overheating not even when downloading and gaming at the same time while still plugged into the charger. Unless your device is faulty or you are on Android 4.2.2, it shouldn't.
This is encouraging, sounds like Samsung got it right with the S4 after the software was updated.
I am also pondering if the Saygus V2 is vaporware.
http://ww2.saygus.com/v2/
for me, my S4 does not overheat 99.9% of the time. if it does happen to overheat, very rare for me, is usually because an app crash or sth. just reboot or remove battery and reboot, and all is fine.

Note 4 Issues

Good afternoon,
I have a AT&T Note 4 and I am at my wits ends. When you try and restart the phone it will just shut down and then it will not power up for 10-15 minutes at all. The phone will also shut down randomly. It will lag and not unlock sometimes. It just seems to freeze. Sometimes on start up it goes to the Odin screen or gets stuck on restarting and never makes it to the colored SAMSUNG screen. I have replaced the battery to eliminate that possibility. The software is up to date also. I have trouble shot this thing to death. What am I missing? The GPS also way off and it started being off a year and a half almost after the phone was new. I am talking 250-500 feet off. It is mostly off while moving making navigation impossible.

i wish there would be a way to make Samsung accept the fact that THERE IS something wrong with our Notes!!!
short verdict - it is dying. install wake lock application, add it to start up and set settings to #4.
accept the fact that your phone will eat the battery faster and one day WILL die completely

Thanks for the response. Yup that is what the issue is. I have been a Samsung fan for years. The fact that they refuse to acknowledge this may drive me away from getting another one. I have spent hours researching and trying to narrow down the issues and find the fix.

Note7 already having issues. Seems like Samsung may have some serious issues going on. Ill have to get my hands on a Nexus and look at it.
Just finished switching to 6P, for better or for worse. Looks great, love the octa core, but the new Google phone is supposed to be announced in a month, and there's no expandable storage. But, I was ready to upgrade and the last few months with my note4 have been brutal. After hearing how many people were also having issues with Samsung (plus the note 7 exploding battery thing), I'm more than ready to come back to Nexus and leave the Note behind. Tbh probably just gonna thrash it until it completely dies lol
