[Galaxy Note 4 Q&A, Help & Troubleshooting] Hashiba Hoo Haa:
Can we get Samsung to fix this for us? A flagship device dying in two years is ridiculous. Incidents like these make rethink about Apple QC, all my old iPhone work. But a fail for Samsung, LG for most of their most popular phones.
[Galaxy Note 4 Q&A, Help & Troubleshooting] Sp0oner:
Funny I told that exact same thing to Samsung UK and they said the warranty is for 2 years if in warranty they fix it if outside the 2 years take it to a repair centre and pay to get it fixed. They really don't care if it fails 1 day outside of warranty so your warranty is the same if it's their budget phone or a flagship device basically don't expect more than 2 years out of it.

I've been waiting for the Note 8 after last years debacle of the 7 but their attitude has really put me off. I'm left asking myself do I really want to pay all that money for only 2 years of use. I'm tempted to go with a Huawei phone as they are so much cheaper but excellent spec phones or go back to iphone and get much better after sales support. I'd never have considered either whilst my Note 4 had been working perfectly but Samsung UK are a disgrace, it seems the US get great support but the UK are treated the same as usual. If I still get a Note 8 i'll be selling it just before the 2 years is up and recouping some money as my Note 4 is worthless now and will go in the drawer as an emergency spare.
[Galaxy Note 4 Q&A, Help & Troubleshooting] Hashiba Hoo Haa:
I seriously think this warrants a class action lawsuit.

A vanilla, stock Note 4, taken top notch care, almost brand new, 2 year old device dies in 2 years.

Even my Nexus 7 2013 with extreme modifying chugs along till date what ever I throw at it.
[Galaxy Note 4 Q&A, Help & Troubleshooting] mxter:
Freezes and restart, many times a day

Exactly same things. Hope u have find a solution. I'm reading everywhere by now,lookin for a solution

Wiped everything, tried with nandroid, rom and kernels. Even a new battery.
[Galaxy Note 4 Q&A, Help & Troubleshooting] senectus:
Nope.

Took it into a local retailer that did trade in's and got $150 off the price of a Nexus 6p, with full disclosure that it was boot looping...
[Galaxy Note 4 Q&A, Help & Troubleshooting] mxter:
Worked.. till now.

..

Until now, solution 3 worked perfectly, together with my new battery. I know many people resolved only changing battery, but not for me. Done 2 cycles and it passed night without any problem.
[Galaxy Note 4 Q&A, Help & Troubleshooting] debernardis:
My advice is several cycles (20? Or more) at least monthly, to keep it healthy. Like a chemotherapy for internal memory.

Also, for reasons I don't know, the "internal memory" option lags and crashes much more than "SD card", at least on my device, even if they should reside in the same memory chip. Are they formatted with different file system, maybe, or accessed by different means? I dunno. These lags and crashes, though, seem to be what is needed to fix storage. When it passes several times the cycle without slowing or crashing the app, it's fine and done for the next month.

When the dummy file generator crashes and most or all the internal memory of still occupied by the dummy files, in order to erase them you have to open the app info page, go to the memory menu and clean data. Then start over ? until several cycles in a row exit without noticeable lags or errors.

Anyone tried 50$ motherboard from Ali-express? Looks like easiest way to stop this samsung nightmar, I'm not experienced with Ali express, could it be really original spare part?!
[Galaxy Note 4 Q&A, Help & Troubleshooting] mads644:
After two years and three months my phone also had randomly freezing and rebooting issues. The rebooting issues were so severe that I 95% of the time could not boot into Android/TouchWizz. Changing battery, wipe cache and factory reset didn't help. Im not impressed with a flagship phone that dies after two year.
[Galaxy Note 4 Q&A, Help & Troubleshooting] Dwillian:
I was going to go that route (although MB from top rated dealers are more like $70). Before I went that way I viewed several videos on MB replacement and it looks rather challenging to me (especially if you've never done something like that before). I finally contacted Samsung and they completely repaired my phone for $70. They also replaced a lot of other failing parts in the process. I had to use my old phone for 10 days while they did the repair (includes shipping time to & from Plano, TX). It's been several months now and my phone still runs like new. I'm very happy with Samsung. The price was very reasonable considering the phone was over two years old. I suggest you call Samsung (1-800-SAMSUNG) before you decide which way to go.
[Galaxy Note 4 Q&A, Help & Troubleshooting] mxter:
Update : With Dummy File generator and a new battery the situation has really improved, even if some lag and restart still remains.

Also raised CPU voltage (+10). Keep u updated.
[Galaxy Note 4 Q&A, Help & Troubleshooting] Saki01:
I've just called samsung service in my country, MB change costs about 300€! Buying used MB or wait 20-30 days from Ali express, sims to be my options :(
[Galaxy Note 4 Q&A, Help & Troubleshooting] Hashiba Hoo Haa:
Sammy needs to be sued for this.

Unbelievable.
[Galaxy Note 4 Q&A, Help & Troubleshooting] mxter:
Only with Wakelock

.. nothing to do, it works only by wakelock. Someone better than me should investigate about that. Anyway, Samsung sucks. I'm thinking about P10plus.
[Galaxy Note 4 Q&A, Help & Troubleshooting] Hashiba Hoo Haa:
Has anybody tried Nougat and if that fixes issues? For me I cannot reach the dummy file generator as the device freezes by then post boot. This is with wake lock installed. Really dead. Very annoyed.
[Galaxy Note 4 Q&A, Help & Troubleshooting] mxter:
I read and report here.

Don't know if works. Until now seems ok

[Galaxy Note 4 Q&A, Help & Troubleshooting] alabamalower:
Same issue here with my SM-N915T Note Edge. I am trying the $70.00 Samsung repair center fix.

Here is what to do if you are in the states and phone has not been tweeked.

Call the 800-samsung phone number and go through the 100 questions the person on the other end will ask and then tell them that you want to send the phone to the Plano TX Samsung repair center.

It will cost a few cent over $70.00 so you need a CC.

You will be given a service order number over the phone.

You will get a shipping label e-mailed to you.

You will get some other instructions on another e-mail.

Print the shipping label and the instructions out.

Follow the instructions and pack up your phone and charge and a few other items if required.

Take the package to your local UPS Store and give it to them and it will be on its way (2 day over night shipping).

I also added a short note describing what the phone was doing, when it was doing it and what I did to get it to work (refrigerator popsicle trick most times).

I think they said a week or two, and I should find out if I wasted $70.00, or if they were able bring my phone back from the doorstep of phone death for $70.00 :)

If repairs cost more than the $70.00 initial fee they will call and let me know the damages and ask what I want to do.

I will let all know how this goes.....

Fingers are crossed that the phone can be fixed and that the $70.00 will cover it.....
[Galaxy Note 4 Q&A, Help & Troubleshooting] Dwillian:
I did exactly what you suggest several months ago. Samsung fixed my phone to like new condition and it has been working flawlessly. I hope you have the same experience.

Good luck!!!
[Galaxy Note 4 Q&A, Help & Troubleshooting] alabamalower:
My fingers are crossed :) I reeeeealy like the phone! Time will tell in a week or so....
[Galaxy Note 4 Q&A, Help & Troubleshooting] Saki01:
I was thinking about your cause. Maybe you should first change that charging part of phone and flex cable and see if it helps. In my case, I think that problems occurred after I started to use fast charge option with second hand charger and cable (of course, I'm not absolutely sure).

After all bought a new Mainboard in China ... everything working fine again ;) costed with shipping 48 € ...
[Galaxy Note 4 Q&A, Help & Troubleshooting] wiebenik:
got the s8+ now but i am sure i gonna fix my good old note 4
[Galaxy Note 4 Q&A, Help & Troubleshooting] Hashiba Hoo Haa:
Can you please post a link to mobo and a video of how to replace the same?
[Galaxy Note 4 Q&A, Help & Troubleshooting] hahn.lelo:
Hi!

I bought this Mainboard:

https://www.aliexpress.com/snapshot...&orderId=84984813888183&productId=32805066913

It took something like 3 weeks to arrive in Austria by standard shipping.

I used this video instructions to change the logic board:

https://www.youtube.com/watch?v=5KpT755hNpM

I had to reopen it after the first try, because one of the connectors on the backside of the logic board wasn't connected properly and the S-Pen wasn't recognized. I had to put a piece of thin carton under the connector of the s-pen sensor so it connected when i pushed the logic board against it.

Now everything is working. No more lags, restarts or freezes :)

If you need some help and live in Vienna you can contact me and Iwill help you with the procedure ;)

PS: Don't forget to read the reviews before buying ;)

I need a help here pls..

I installed Dn7 rom then after i did this the phone just opens and stay with me awhile then reboots and the sim card is not working and every second a popup come *settings has stopped* and i cant open it
[Galaxy Note 4 Q&A, Help & Troubleshooting] hahn.lelo:
Sounds to me like major kernel/baseband issue ... I'd try to flash stock rom via odin... afterwards you could try to install Dn7 rom again by reading the flash intructions and requirements carefully ...

If it is an hardware issue there should be no difference which rom your're using ..
[Galaxy Note 4 Q&A, Help & Troubleshooting] Kriture:
Must be a specific version or as i have the bootloader on?
[Galaxy Note 4 Q&A, Help & Troubleshooting] kraken77:
Just wondering does it only occur on stock roms? What if on custom roms? Does it shows same behaviour? Do let me know cause someone is selling me his note 4 with really2 cheap price because of this issues. If it can be fix by installing custom rom, i dont mind using RR since its really stable for my daily driver.
[Galaxy Note 4 Q&A, Help & Troubleshooting] Pari5ian:
I've had all the problems mentioned in this thread with my Note 4 SM-N910F, and it's currently being kept alive with WakeLock. As I love the phone so much I took a chance and purchased a second hand one, it's taking longer and longer to get the current one back on once it's off, same model and it also has Android 6.0.1 installed however it's not displaying any of the problems we've all been experiencing.

It re-starts, and switches off and on as it should, unlike my previous one which can take a whole day to come back on once off. There have been no issues whatsoever and that's with everything that was on the old phone transferred over onto the new.

So what is the difference? Why are two identical phones, with the same apps, software etc working like two different models? After transferring my data I decided to install the latest update which I'd put off for a month, that bricked the phone! When I eventually managed to get it back on I was doing a factory reset and yep, that bricked the phone! Hours later and I managed to get it back on, and touch wood it has stayed on overnight.........but what next? There is also an update showing on the new phone, but there is no way I'm installing that.

Samsung should own up to what they have done to the older models, most of us would prefer no updates rather than an update that sets out to sabotage our devices! Annoyingly, when these facts are brought to the attention of SamsungUK via Twitter they pretend as if it's the first time they've heard about it and their stock answer is to send the phone in for repairs....yes, but we don't all have a Samsung Service Centre that is easily accessible.
[Galaxy Note 4 Q&A, Help & Troubleshooting] Hashiba Hoo Haa:
Thank you Hahn Lelo. You are a brave and a talented man! I absolutely could not do what is shown in the video. The tiny connectors and the seperation of all the parts seems like a complex affair. I am Canada, so there goes my chance to get help. Thank you for the links.
[Galaxy Note 4 Q&A, Help & Troubleshooting] Sp0oner:
That doesn't look anywhere near as bad as I thought it would be! Separating the screen from the case would be the worst bit for me. Also the link to the board doesn't work now so must be out of stock/not selling it.

Hi, I started having this problem 2 weeks ago but my phone still cover by warranty. Someone have sent his phone with this problem to warranty and they will repair it?
[Galaxy Note 4 Q&A, Help & Troubleshooting] mxter:
Also custom ROM

Mine is Simplerom, worked for years, now no more. Tried every wipe and reinstall and kernel
[Galaxy Note 4 Q&A, Help & Troubleshooting] Hashiba Hoo Haa:
Time to go back to 3310. I absolutely want to hit Samsung out of the park.

We all should do a collective poll including imie nos to catalog how many devices that have failed and where. To my horror I am also reading similar failures with other non Note 4 Samsung devices.

And then hold Samsung by the balls to improve their manufacturing, parts and QC and ensure device is fixed. If failure is now happening across board, Sammy needs to own up.

Note 4 Rebooting solved

Hello all, like all of you i too have been having these constant reboots and slow down for around two weeks, i have read this forum in the hope of answers to no avail. I love my note 4 so wasnt read to give up and came across yet another suggestion by somebody else on another forum and decided what the hell and so far things are looking good. I have had 24hrs of moderate use with no reboots or slow downs. So Go to developer options and under 'drawing' change the following to 0.5, window animation scale, tranistion animation scale, animation duration scale. I have no idea why this works or what it does but my note 4 is like new now. I no longer need wake lock app. Ler me know if this helps for you. Credit to the person who discovered this.

I replaced battery and problem was solved
[Galaxy Note 4 Q&A, Help & Troubleshooting] Pari5ian:
Thanks for posting this, I'll give it a try on my faulty one. Although, once mine is up and running it works perfectly with WakeLock but if for any reason the phone shuts down due to re-starting it or the battery dying before I've had a chance to charge it getting the phone to switch back on takes hours. So the test for me will be if I'm able to switch my phone off and back on straight away.

I'll report back.

ETA: Well, I changed my settings and the ultimate test was to switch the phone off and on/restart it! It suprisingly came back on more or less straight away, and that's the first time its done that since the corruption. Anyway, I woke up this morning and the phone is dead!!

I am therefore going through my usual routine of taking the battery out and leaving it out for as long as is necessary before the phone decides to switch on! Yep, I am definitely not doing any software updates on my 2nd handset after all I don't need two bricks.

Thanks again Spunkymonky and to whoever discovered this, I shall keep trying all suggestions or failing that I just need to ensure that my phone is always on.
[Galaxy Note 4 Q&A, Help & Troubleshooting] woldranger:
My faulty Note 4 was set to that before the issues, so it's certainly not a cure-all, but it's great that it's working for you and it's a 30 second attempt for other people to give it a shot - it's actually a setting that I recommend anyway!

This issue started right after upgrading to the latest update (august update for android 6.0.1). Seriously under impression that this bug was intentionally added to the firmware in order to force people throw away their phones and go buy new. Trying to downgrade back to March firmware, not sure if it's going to help.
[Galaxy Note 4 Q&A, Help & Troubleshooting] hahn.lelo:
Unfortunately it's an hardware error! I didn't want to believe it first time it happend to me - and due to an app solving the symptoms - but after some tests (heating up the Mainboard in the oven) I realised that the mmc chip was the cause of this happening. While update the chip gets too hot and the welded connection is becoming fluid again causing a connection loss. That's why my phone was working again for 3 weeks after heating the Mainboard up in the oven while putting some weight on the mmc chip. Then the same s*** started again ... I retried the procedure with some modifications - a bit longer and a bit more heat - and fried my Mainboard to death.

After all I bought a new Mainboard in China via Ali express and replaced it. Now I am with up to date firmware running the device for 1 month and everything is fine!

But we all could say thank you for this f***ing poor quality to samsung ;)
[Galaxy Note 4 Q&A, Help & Troubleshooting] pmunin:
Can you please send a link to the specific item on aliexpress you bought and how much you paid? I have SM-N910T 32GB. I see this one, but it says "Brand Name:HHXHH". WTF is HHXHH?!

How did you figure out that the one you got has clean IMEI #?

Also does it mean that I also can get SM-N910T3 32GB?

The hardest part during replacement is not to damage the screen. Is there any youtube video you used as an instruction for replacement?
[Galaxy Note 4 Q&A, Help & Troubleshooting] hahn.lelo:
See my post posted earlier ... I had no problems taking off the screen! The harder part is to reconnect the connectors on the backside of the MB - I had to put a piece of carton under the cable connector for spen digitizer.

I have a 910F and you should check if the board fits your device ...

UPDATE***UPDATE

1. Sent the phone in.

2. Had an estimated repair date of 14AUG2017.

3. Missed that date.

4. Called the 800 number and they called the repair center. Said it will be finished shortly.

5. Received an e-mail the next day saying repair completed.

6. Took a few days to work it through their QA ck and such.

7. Received an e-mail with tracking # after a few days.

8. Phone was delivered yesterday.

9. Service Repair statement said "Replaced PBS".

10. Three items were listed:

a. GH82-09073 - SVC PBA-PBA MAI (SALE):GH82-09073A,SM-N9

b. GH96-07821A - ASSY SUB PBA(SM915T);SM-N915T,USB

c. HG97-16560B - MEA REAR-MELOT:SM915T,TMB,BLACK

11. They also sent a new Samsung USB cable and travel charger.

12. Opened Samsung SmartSwitch and hooked the phone into my PC.

13. SmartSwiched upload a newer operating system and updated the phone.

14. I then reinstalled the backup I did just before sending the phone in.

15. Installed my TRACFON SIM and additional memory.

16. Now at boot up the phone says invalid SIM and is asking for the unlock code.

17. Everything else seems to working GREAT.

18. Samsung did say that the repair would wipe EVERYTHING and it would be reconfigure back to original specs.

19. Called T-Mobil to see if they would proved me the "unlock number" for the phone.

20. T-Mobil said I needed a T-Mobil phone number (I have TRACFON #).

21. T-Mobil said when the provide an "UNLOCK NUMBER" they tell their customer not loose it or forget it.

22. Not sure if I can even reach the 3rd part seller, much less if they even have a copy of the "unlock number".

23. Looks like my only option now is to "jailbreak" the phone.

24. Did a little looking around and it appears that the SM-N915T is easy to "jailbreak"

25. My next adventure.

26. My cost so far is:

a. $230 initial cost on WOOT

b. $30 credit back from WOOT because the phone was hosed.

c. $70 to send to the Samsung Service Center.

Sooo.....$270.00

The adventure continues :)

I think restarting has something to do with device security. I did full wipe cache partition, full wipe data/factory reset and then flashed the stock rom. After flashing the rom it asked me to allow installing device security updates automatically so just disabled it and did not activate the device security from smart manager ... after that it worked good as before no issue ... using exynos MB ... hope it will work for you

Edit :-

Well freezing and rebooting started again after 15 days ...
[Galaxy Note 4 Q&A, Help & Troubleshooting] broacher:
After several days searching for answers, and countless stories from all around, my best 'conclusion' is the trouble began with a recent security patch (which automatically got installed) that scorched the internal system SD card by demanding too many read/write cycles on its NAND controller bits.

So it looks like it's both a software AND a hardware problem. But the Samsung software upgrade is likely the source of the hardware problem.

Some people on rooted devices have worked out a way to reformat the damaged areas in the internal MMC to route around the damages, but if you're like me and don't want to go down that rabbit hole, the only solutions seems to be Wavelock and the Developer Options tweaks already mentioned. Just don't power down without expecting a lot of hassle powering up again. That is, battery removal, power switch drain off, and possibly more (battery in freezer, etc.).

And, if you're thinking of buying a used Note 4, be absolutely sure you do a complete power down and restart before buying. Something tells me that the used market will soon be flooded with these devices.
