[Galaxy Note 4 Q&A, Help & Troubleshooting] censa:
OMG, my phone now is completely dead ( happeneded 10 minutes ago). While i was using it, (normally, before turning off and start to rebooting spontaneuosly, it "freeze" any activity i was doing at the moment---> phone doesnt respond anymore, both touch and phisical button are "insensitive") it gave me the same freezed interface, but this time the screen turned yellow with the current interface still on (like if someone has spilt some yellow paint on the screen, but with the screen still on, and "freezed"). Then the phone shutted down completely and didnt do the spontaneuos reboot. So, i tried with power button, but nothing. I've plugged the charge cable in, but NOTHING. Changed the battery with the old one, but nothing happened again. I've tried to boot from Download mode, but even in this case the boot process stops at the first interface and, instead of rebooting again for some time like he was used to do, i turned off completely. Even the recovery doesn't work, in fact while is trying to access the recovery mode, it shut down completely even in this case. The fact is that right now i dont have replacement phone suitable for the note4 sim, and this is pissing me off a lot! How should i have to proceed?

K - Take the battery out and put the phone in the freezer for about 15 minutes - Put the battery back in and see if it boots normally..

ok, i've tried to change battery, and things seems to WORK!!! phone just boot perfectely, and the charging cable test didnt failed!

For now i have a """"working"""" phone..what do i have to do now?

See how it runs for the next day or so - If you continue to have random reboots - I'd start with Flashing the Stock Firmware as I outlined in a previous post - If you end up with the same situation where the phone won't boot unless you put it in the freezer - I'd be thinking about getting a new motherboard - or a new phone....

okay, first thing im going to do is to make a classic drag and drop backup on my pc, then i'll follow your instructions. I'll keep you update. I'm in debt with you, thank you so much for (far to now) your help and support, i've really appreciated that.

PS: if i change motherboard will i lose all of the data that are on the phone right?
[Galaxy Note 4 Q&A, Help & Troubleshooting] shaggyskunk:
You more than welcome! I know that it sucks when a trusted device starts to give you grief :)

Yes you will lose your data when you replace the motherboard - But if you use TWRP and make a Nandroid backup - Save it to your external sd card and then you should be able to recover most everything.

Good luck and stay positive ??

I read your story man..

I would suggest not to change motherbaord as new one is also gonna behave same like me(i have tried same thing i had to sell my phone then)

IMO samsung new update kills note 4 . no matter what you try to save it, once you got this bug (or whatever you call it) it will kill your phone and you are bound to buy a new note 8 or ......

[Galaxy Note 4 Q&A, Help & Troubleshooting] censa:
So, few days have passed, and as said, i've got some updates for the ones who are "interested" in my problem.

Without any working phone i was "forced" to use an old iphone4 of one of my friend (i say forced because 2 days ago, i was at school with my note4 who, as "usual" has turned off completely...during my way back home, i got into a car accident, with an idiot who ran a STOP SIGN without looking or slowing down, at the moment of the accident my phone wasn't working, and if it wasn't for the other guy involved, it would have been a worse situation, because my school is far away from my house, and it's not safe to drive a high-damaged car)....after few days with Apple, i decided to "restore" the phone i had used before moving to Note4...so i took out my old galaxy s3, with cracked glass (at the time i've put some tape on the corner, to prevent glass splinter to damage me/my phone). I've already ordered on aliexpress the replacement glass haha. While using my S3, i've tried to work on the note4 too. So, i've tried to restore the stock firmware, but nothing has changed..i've kept charging it event if it was at 100%, and it worked a little, since when taken by "hope", i've switched sim, to try to use my note4 again, but the problem started again (this time the situation is VERY BAD, the phone just shut down after the first interface, it doesn't reboot for some times like it used to do few days ago). So, even if some of you disagreed with that, i've bought a new mobo for the note4, just to try "everything" (i've paid it 50 bucks, not too much, it's worth to give it a try),if even with a new mobo the problem persist, then im going to proceed with my assurance (the "expert" exit if the bill is over 1000€, and im going to stay under that "amount"). That's it. Im gonna post other updates in the next days.

I saw my old motherboard today and found something is leakage in motherboard near the battery points. (in red circle) can anyone explain what is that ? Can i repair this if i change this IC or whatever it is called ?

Note :- My phone was running on Cpu wakeup application. One day my phone charging and later after 2-3 Hrs when i return to my it phone, i found it very very hot like fire and since then it did not start, even after freezer trick. so i changed motherboard and sell it. and now i am left with my old mother board.
[Galaxy Note 4 Q&A, Help & Troubleshooting] censa:
ok, so after mouting my new mobo, the phone started working without a single problem (it was like he was brand new haha), but unfortunately the mobo was still running on Android 5.11 , and after trying to update by OTA, the phone displayed me a message : "impossible to install update". So, i decided to do that by myself, and with Odin, i put the lastest Marshmallow update avaible for note4 on my smarthphone and, suddendly, the problem i was having with the old mobo recurred on the new one. What if it's not an hardware problem but a software one? [MENTION=4351374]shaggyskunk[/MENTION]
[Galaxy Note 4 Q&A, Help & Troubleshooting] shaggyskunk:
Consider the shear numbers of Note 4 devices sold - I'm quite certain that it's definitely a hardware issue - It is possible however that a Firmware update might reveal the underlying issue with the hardware. It's been mentioned a few times that Samsung uses different suppliers for their manufacturing process - My belief is that the inferior hardware supplied by certain companies is ultimately the problem.. Sorry to hear about your situation. At this point I'd call Samsung (if you haven't already) or think about cutting your losses and just replace the device.. ?

Samsung= Crap...... look at there exploding batteries. Id say it definately hardware built on the cheap, sold at premium prices as a device.
[Galaxy Note 4 Q&A, Help & Troubleshooting] shaggyskunk:
You're entitled to your opinion - But I strongly disagree with you!

Some of the Note 4 devices are vulnerable to the issue which this Thread is about - The Note 7 was a huge mistake - But I challenge you to name one manufacturer that hasn't had any significant problems! Especially when you consider the shear volume of devices produced!

But thanks for dropping by with your unnecessary & completely off topic comment!

Why are you even posting here considering your opinion of Samsung? ?

Have you guys tried with a new battery ? Just a thought ...
[Galaxy Note 4 Q&A, Help & Troubleshooting] logosA:
I have. I have bought a new original Samsung battery. No difference, the phone is showing the exact same problems.

If restarted, dont boot up, unless put it in the freezer before.

Even this way, my phone needs a ext sdcard with a debrick image in it, which helps it boot up, otherwise nothing.

The last week my problems got even bigger, while on charger (original fast charger) phone started to smell like burning plastic.

Took it of charger and noticed some smoke coming out og the port. Cable got black and melted, phone stoped to charge in every charger.

After some tries with deferent cables and chargers, find out that could only be charged through pc, with a certain cable in a certain usb port and nowhere else. That condition lasted 1 week or so and again, smoke, melted cable, now phone cannot be charged anywhere.

Got tired trying and put it on a drawer. After 10 days, ordered new charging panel and also ordered a replacement motherboard.

Although in the meanwhile I bought a new phone , I cannot give up on my Note 4, so i hope I will be able to resurrect it.

I am so jealous seen people flashing everyday a new rom and waiting for Oreo to come soon now :(

So I guess I am a flash -holic , I decided to keep my Note 2 and fix my Νote 4 and use them to flash custom roms

I bought a ZTE BLADE with 3Gb /32Gb dual sim to keep it for my life and work and the other 2 for my love- custom roms :)

Please dont say I am foοl , I know I am.....

My story is exactly same like you , but in the last after changing the motherboard i sold my note 4 because it was getting hot with a new motherboard also.
[Galaxy Note 4 Q&A, Help & Troubleshooting] echomanX:
My note 4 is over 2 years old (has been rooted since I bought it with no problems ever) and worked flawlessly until my last update (Aug 2017), it then started running slower, freezing and restarting. I thought and still think Samsung inserted code into its latest updates to cause these problems in order to coerce happy users of its older phones into taking out a loan (@25%) to purchase their €1,000 note 8's............So I changed the battery and noticed the freezing and restarting getting worse, the new bat would only charge to 86%, sometimes I would have to swap it out with another in order to get it to boot.

After reading your thread and immediately installing Wake Lock, and after following your steps the issue is now gone, the battery now charges to 100%, and the phone is working as well as it did formerly. A small price to pay for satisfaction is the slightly higher battery drain. Many Thanks for your post.

While thrashing around the web looking for help I also found this procedure on another XDA note 4 thread that may be helpful to others with new batteries that won't charge to 100% (Wake Lock is also recommended) :

1,open dialer and dial *#0228#

2,after dialing *#0228# the battery status menu will popup.

3,hit ( quick start ) at bottom of the screen in red color

4,hit ( yes ) and go to settings/battery and disable fast charging for 1 charge only.

5,power off the phone and charge to 100%.

6,turn on the phone and if it shows 97,98,99 plug in charger again and charge to 100%.

7,once it charge to 100% unplug charger and this will create new battery calibration status automatically.now you can enable fast charge again.

8, Next go to play store and download wakelock power app and install it. Open the app and hit (PARTIAL WAKE LOCK) as in screenshot below.

This app will help prevent the device from random rebooting and freezing ths app does not require root access.:good.

My battery started not charging fully, only charging to 77%, so I rebooted it and it went dead, nada, stone dead. To fix this issue I found this fix:

Take out battery, sim card, and mem card. Install back cover. Place phone in ziplock sandwich bag and seal. Place bag into freezer for 20 minutes. Remove bag/phone from freezer, reassemble battery, sim and mem cards. Press the start key and phone should boot(mine did). If not, plug into Samsung fast charger and try booting again.

This works.

Galaxy Note 4 freezing issue fixed for me by updating to new ROM

Good News (Surely for me. Hope it's good news for other Note 4 users as well)

I'm posting this to many forums as this might help at least few and hopefully many note 4 users.

Sammobile now have latest ROM released for Galaxy Note 4 dated 2018-Jan-04th.

This ROM has fixed all my Note 4 freezing issues including random restart and booting to download mode.

Issues i had before this ROM:

My device freezes for every 5 to 10 seconds and won't respond for at least 5 to 10 minutes. and this repeats forever

Sometimes while restarting ( while normal restart or force restart by removing battery), It enters into download mode.

"wake lock" app from google store fixed the first issue for me. Device is fine except it consumes extra battery.

This is what i have done while flashing new ROM:

Removed external SD card ( took all backup to SD while keeping the "wake lock" app running in background)

Wipe all cache from "Recovery mode"

Flash the downloaded new ROM from sammobile using "Odin (3.12.7)"

-- This is important, Updating to this ROM through manual update option in "Device update" didn't fix this issue completely although freqency of freezing issues came down.

-- Open Odin using "Admin previleges"

-- When flasing through Odin failed because of some error, I have just removed the battery and went back to download mode immediately and "Start"ed the process in Odin again. It worked this time.

Although i have seen slight gliching right after this update ( such as screen freezes for 2 to 3 seconds randomly), Once i have let all the apps updated from google play store and restarted the device few times ( two times precisely), Now it's working perfectly fine. Just like old times.

Note:

My Device model: SM-N910G ( India - INS ) -- I think recent ROM is available for most of the other models as well.

Thanks,

Durga

After 24 hours of using this ROM, looks like the device is slowly starting to give the freezing issues again.

It is still better than before but the way I see it, it may act like before eventually in a day or two :(

Kernel flashing

I had the same problem with my ROOTED Note 4 SM-910F running on stock MM firmware after the last Samsung update.

Flashing a new kernel completely solved the problem for me - no more freezes and sluggishness after unlocking the phone, reboot errors with eMMC, restarts etc...

I just flashed the latest v3.1 flashpoint kernel (https://xdaforums.com/note-4/snapdragon-dev/kernel-flashpoint-v3-1-stock-n7-ports-t-t3727407) over stock one. Now, everything is working as before. No need to have partial wake locks at all!

How many of you have SM910G?

I think this model has low rate of having this freezing and restarting Problem
[Galaxy Note 4 Q&A, Help & Troubleshooting] zenn-:
I do and I have exactly the same issues that everyone on this thread is facing. I think it might have more to do with the chipset (Snapdragon variants) than 910F vs 910G.

Has anyone else tried flashing v3.1 kernel?
[Galaxy Note 4 Q&A, Help & Troubleshooting] pcp20us:
I flashed v3.1, and my phone turn off..... I restored my stock rom, now i have a bricked phone... It needs 30 mins in the freezer then the best i can get is the samsung logo and it freezes. that plugging it into my pc holding down the power button and insreting battery. I cannot get to recovery mode which is a bad becasue thats where i need to get to.

ITs worth a try. My phone needs the freezer treatment to get it to boot into any mode and after the flash it became worse
[Galaxy Note 4 Q&A, Help & Troubleshooting] ^DiMoS^:
Sorry for my noob-iness but i want your opinion...

So 1-2 days ago my Note 4 (sm-n910f) started freezing up while using it... could it be emmc failure coming my way?

Some backround for my device:

It's not rooted...i have it since december 2014 and somewhere around at 2015 one day couldn't stop rebooting so i sent it to service and they replaced my motherboard cause they said it was motherboard problem...when i got it back was perfect though again around 2016 it started rebooting itself here and there randomly and mainly i thought it was software problem...sometimes i went 2 months without random reboots and sometimes i got 1 reboot a day.

now it usually reboots or go to boot loop if im low on battery until i plug it in to the charger then its okay again and boots normally!

Could it be just battery problem?

Took the androbenchmark test too:

Edit: Nevermind... just did a hard reset on the phone and while setting it up i restarted while it was on the charger and the download screen came on with mmc_read failed ... i took it off the charger and took of the battery and put it back then opened it and it runs for now... until it completely dies! :(
[Galaxy Note 4 Q&A, Help & Troubleshooting] MaxBPL:
I've tried that kernel and it's still freezing. I'd decreases though from 6-7 reboots to 3-5 per day and mostly when battery is below 50%. Also it is decreasing battery level drastically after that level.

It looks like memory error for me. I've started to wondering if maybe little re-flow wold help. High temperature during usage could actually heat up components in some places and it will be right if some update would increase battery consumption.

Well nice step Samsung...

Have anyone got further suggestions?

Ps. Trying now with Wake Lock application on new kernel. So far so good!

Ps2. Flash of kernel solves my issue with losing Wi-Fi passwords after reboot.

Hi.

I ve been on this thread for a long time. I have tried every option with my note 4. The turning off is getting worse and getting it to boot, harder again.

So want to get a new phone. The note 4 does everything i need of a phone and i like the camera.

So to replace the note 4 with something equivilant will cost > $700 AUD... With something like huewi mate 9 or LGv20 etc.

Is it worth buying a new note 4 ( if you can find one) ones i see advertised are around $300 AUD, need to make sure they are brand new.

So anyone gone down this road to replacing there note 4 with a phone thats not going to cost $1000 AUD or more.

On last Sunday my unrooted SM-910F suddenly got this issue. I had it for 2 years and 8 months and the warranty has expired 8 months ago. What is interesting, the last update I had was like a few months ago, so it indicates that it is either a hardware failure or Samsung deliberately spoils the working mobiles in order to force people to buy the new ones. Sounds like a conspiracy theory, but it is not unbelievable.

I have read this topic and have tried a few solutions - here are my findings:

WakeLock solution works perfectly. I actually do not see any issues with the battery performance (however, I have replaced it a few months ago, so it is still pretty new). As the constant notification of WakeLock is a bit annoying, I have however searched for the other solutionsm,

FlashPoint Kernel v.3.1 - I have rooted the phone and replaced the stock kernel with this one. Unfortunately, although everything else is working fine, WakeLock is still required - without it the phone still freezes/restarts.

Hope that helps.

If Samsung was "deliberately" designing their devices to fail - How would you explain why my Skyrocket - Note 2 - Note 3 - Note 5 Are all still running perfectly fine? The Note 4 issue (which has NOT affected all of them) IS clearly either a design or hardware (remember that Samsung has a number of parts suppliers) issue - It's DEFINITELY not a "planned" effort on Samsung's part to get their customers to buy new products! ?
