[Galaxy Note 4 Q&A, Help & Troubleshooting] MaxBPL:
Hello.

I quite do not understand what you meant by "dead" according to your Notes phones.

My 910F was not responding, resurrected, flashed inappropriate, downgraded by mistake and lost all funtions again (freezer helps) and it's finally working like a charm. I've even seen some eMMC memory fails during the week that I was dealing with Note.

For now it's the best phone that I've had (especially with S Pen support)
[Galaxy Note 4 Q&A, Help & Troubleshooting] notachamp:
Sometimes if your phone shutsdown and won't turn on again you have to remove the battery and wait some hour, then when you start it again make sure to not turn off ur screen untill you open the wakelock app again and check if it's on partial mode. That's what i did yesterday and that gave my phone the life back. My phone works now 1 year with wake lock app, you don't need new kernel, roms ( and belive me the best working rom on the note 4 is the original) or anything just that app and 'the remove battery and wait trick" and to check if partial wacke lock is on.

Maybe because Samsung's earnings for 2016 were:

49,596,900,000.00US Dollars

You really think for a "New York minute" That Samsung needs to sell you a new phone?

I changed My mobo and it was working fine unless I update it to 6.0.1 (Shaggey suggested me) (and he sounds like samsung employee) and my phone again was behaving like freezing etc. i had to sell it and i wont buy samsung again because i agree with all you have said here.
[Galaxy Note 4 Q&A, Help & Troubleshooting] shaggyskunk:
LOL "Samsung employee" - Try Finance ?

This post is NOT directed at you btw!

Most Carriers have phones with no upfront costs - Why not quit complaining about the Note 4 issues and trying to spin some kind of conspiracy crap that Samsung did "it" deliberately... That is Complete & Utter Nonsense!!

It's been posted so many times that Samsung (like every other manufacturer) sources their parts from a number of different suppliers and maybe Samsung did mess up on the design - or maybe one of their suppliers messed up - But it's absolutely freaking ridiculous to suggest that the emnc failure was deliberate!

I've got 9 Samsung devices and only one has any issues.... Buy 9 cars and see if you're that lucky!

Me & my family have owned samsung phones since the galaxy S. After the emmc chips crapped out of a S3, S5, S6edge, S7 (original AND replacement motherboard) and my Note 4 in my family ( mostly just after warranty), we have stopped buying samsung phones.

Needing wakelock to keep it going indicates your emmc chip is dying. Been there.

Thanks arnookie. My Note 4 is still "working" for a week now. I guess that it is confirmed that the emmc chip is the root of the problem.

Just found this video, confirming the fix...

[Galaxy Note 4 Q&A, Help & Troubleshooting] arnookie:
The emmc chip was not soldered to the mainboard properly. Samsung should have recalled them for reballing. But as usual they don't care. Especially after warranty expired on most before the chip started to loosen from the board. This help press it back into place. I'm glad it helped you. ?

My Note Edge was running now without any problem for about 12 hours.

It worked for me. I did get any fault message(s) during freezing and restarting.
[Galaxy Note 4 Q&A, Help & Troubleshooting] The Sponge:
Well, it's not that bad for me. All I have to do is make sure that the phone is always charged, and I won't have to worry about it not restarting properly.

One trick I've learned that works perfectly for me even when it does shut off (due to low battery power), is to take out the battery, put it back in, enter download mode first, take battery out again, put it back in, and then boot like normal. Works like a charm everytime. Hopefully I will be good.

I've been having the same problem since Saturday and just found out this topic. I installed the Wake Lock app and did the change half an hour ago; so far, so good. I'll report back in a couple of days.
[Galaxy Note 4 Q&A, Help & Troubleshooting] lisbon2004:
it's time to replace your battery (it lasts about 11-12 months).

it can no longer provide amperage, causing random reboots or shutdowns.

and thank god that it's replaceable.

this is why one should NEVER buy a phone with the non-removable battery.
[Galaxy Note 4 Q&A, Help & Troubleshooting] golden_m:
bought new battery (OEM), did not help.

Wake Lock app is the only way to keep my phone in working order...until i restart it.
[Galaxy Note 4 Q&A, Help & Troubleshooting] hathertonwood:
Wakelock is only a temporary workaround - mine was getting slower and more unstable even with wakelock - it was so much slower than my old Note 3 I use as a backup. I tried a new battery and firmware reflash did not help. So I got Samsung to replace the motherboard - 2 year guarantee so no cost. Completely cured the problem. The phone is faster than I ever remember it and interestingly the battery life is so much better. as well. So people with this problem should get their motherboard changed while there are still stocks available - heaven knows what stock there is with so many failing.
[Galaxy Note 4 Q&A, Help & Troubleshooting] golden_m:
where are you about that you got 2-yr warranty?
[Galaxy Note 4 Q&A, Help & Troubleshooting] Jon_G37S:
I was having the same issue with mine, problem solved!

After spending many hours over several days trying to solve this problem, I came to the conclusion that although my battery was fully charged my Note 4 phone would only actually run while it was plugged in. As soon as I would unplug it, it would shut down and go into continuous boot loop. Therefore, it seemed to make sense that somehow despite the fact that the battery said 100% it was not able to keep the phone functionality. I went into a Verizon store in Boston and they just happened to have a new replacement in stock, we tried it and VOILA problem SOLVED!

I would definitely suggest trying this to solve this issue!
[Galaxy Note 4 Q&A, Help & Troubleshooting] SteveRiley:
Yes, please tell us more about this two-year warranty thing?

Aster Using Partial Wakelock atleast this freezing and lagging issues is solved.

But why is this problem what is the reason behind it ?
[Galaxy Note 4 Q&A, Help & Troubleshooting] yugoport:
Mine was replaced under warranty, unfortunately they hadn't note 4's in Stock anymore so they gave me a S6 Edge+ , it's significatively faster and smoother than the note 4 but feels a massive downgrade, less battery, no sd card, no IR , no S Pen , no removable battery.. at least is lighter and feels more portable although the screen is the same size.
[Galaxy Note 4 Q&A, Help & Troubleshooting] golden_m:
was it under one year Samsung warranty or extended warranty from carrier/third party?

[Galaxy Note 4 Q&A, Help & Troubleshooting] ga4a89:
I suffered from the same symptoms. Have any of you tried Wake Lock (set to partial) ?

After wakelock the battery drain is greater but the phone is usable and in fact very snappy! If you really need something to bring it back to life, try wakelock and tell me if the problem is still there. Since my phone started working properly, I concluded that it's a hardware fault.
[Galaxy Note 4 Q&A, Help & Troubleshooting] hathertonwood:
Yes it is a hardware fault - looks like a faulty batch of components with lots of Note 4 going down roughly at the same time. In the UK its a 2 year warranty by Samsung. A new motherboard completely cures the problem.
[Galaxy Note 4 Q&A, Help & Troubleshooting] DaniLoveSky:
Wake Lock worked well for me preventing the phone from the freezing and restarting problems.

Thanks for suggesting this fix!

---------- Post added at 02:00 PM ---------- Previous post was at 01:51 PM ----------

As many on this thread have noticed, starting the phone after a reboot may be a challenge. I suffered from this too -- sometimes it took me a dozen attempts before the phone started to boot.

And now, after updating Superuser app and rebooting the phone I cannot start it anymore :( I tried all the button combos I new (VolumeDown+Power, VolumeUp+Power, VolumeDown+Home+Power) with no effect.

Is there any special trick to "jump start" the phone?
[Galaxy Note 4 Q&A, Help & Troubleshooting] golden_m:
put the phone and battery to freezer for 2-3 minutes and try again.

yes, i am not kidding
[Galaxy Note 4 Q&A, Help & Troubleshooting] hathertonwood:
Leaving mine to call down for several hours also allowed it to restart. But to solution is a new motherboard.. maybe there should have been a recall for this too!

[Galaxy Note 4 Q&A, Help & Troubleshooting] ronin201085:
I'm starting to have the same restarting problem, all of which begun over the last 2 months. Its a completely stock phone and was actually replaced 6 months ago because the screen stopped functioning.

First (maybe once a week) I would have the phone sitting on about 70% charge and it would freeze, reboot and come back up with 0% battery and die.

Then last week when using my camera the phone froze and reboot, and just continually rebooted until I put it on charge. Once 100% it was fine there after.

Now today it began rebooting when i tried to use the camera, got hot and rebooted continuously. I charged it to 100% but no change, I also tried booting in to Safe Mode which made no difference. Ive just noticed now that I can boot the phone and use it, only whilst it is plugged in to the charger. If I unplug it, it will begin a boot loop again.

Im now at the point that it is still just within its 2 year warranty so I'll backup what I can and send it off for repairs.

Changing motherboard is the only solution I think
[Galaxy Note 4 Q&A, Help & Troubleshooting] SteveRiley:
Wait, what? This one change allows the phone to enter deep sleep for more than 20 or so seconds and then wake up normally, with no freezing or reboots?
[Galaxy Note 4 Q&A, Help & Troubleshooting] hathertonwood:
This must be hardware . My issues which were like everybody else were completely solved by a motherboard change and the touchwiz permissions are turned off. The phone is so fast now, battery life so much better and no crashes freezes or reboots at all. Its like a new phone. Will keep it running now until something better with a replaceable battery turns up.
[Galaxy Note 4 Q&A, Help & Troubleshooting] dunnenick:

This also worked for me. Added permissions for touchwiz for storage and touchwiz easy for contacts.

I previously tried removing sd card/sim card/ two factory resets / clear cache partition. none of which worked.

I have n910g model.and i have bought it 1.5 years ago.As i was having same issue since past last week.I came across this thread and amazingly I am not alone with this sinking ship.I have read the full thread and temporary solutions will try some of them and see if problem persists or not for 2 weeks.will post later on. But one thing i thing i got from past recent incidents of Samsung with note 7 and with also this note 4 this would be my last Samsung phone. I am done with this company. One thing we can all note 4 users can do that let the Samsung know about this problem somehow using Facebook or any other social media. So those F***king A**hole can see how bad their reputation have become.
[Galaxy Note 4 Q&A, Help & Troubleshooting] MissionImprobable:
I am on my third replacement Note 4, and even have a spare battery. Yes, I don't get the boot loops and plug in icon and shutdown with the new battery that I did from the old one, but I still get resets when it falls below 20% or so. I had no issues with random resets until the MM update. It seems to be a software problem as well.

TouchWiz Permissions

The previously mentioned solution where permissions for Storage and Contacts in the Touch Wiz system apps are granted has helped a little, but did not solve the issue entirely.

My phone: AT&T Note 4, MM 6.0.1, No root

My Symptoms: Newly occurring lags, and frequent freezing and reboots.

Things I tried that didn't help: Factory Reset, SD Card reformatting, removing SIM card

This worked immediately: Granting Touch Wiz permissions.

App Manager --> (show system apps) --> TouchWiz easy home --> Permissions --> Contacts (on)

App Manager --> (show system apps) --> TouchWiz home --> Permissions --> Storage (on)

I have now also installed the Wakelock app on level 4. So far so good.
[Galaxy Note 4 Q&A, Help & Troubleshooting] jult:
This silly new permissions model of MM Android 6.* blows. It's security theatre, and it doesn't help one bit, as the last pwn2own showed.

My N910C also reboots since about 3 days now.

It reboots when I start to play a YouTube video, and it reboot randomly here and there, but it all seems related to memory and/or video-chip.

Wow, what a huge disappointment to see I'm not alone with this. These machines cost us 600 euros or thereabouts. What an enormous ripoff.

I'm going to try and get a financial return from Samsung with my warranty and I'll be using the fact that the Note 7 debacle shows how bad their QT is.

[Galaxy Note 4 Q&A, Help & Troubleshooting] Kitamba:
I've had this same issue on my note 4 SM-N910W8. I've had it on stock 4.4.4 until I updated it pushing it all the way to 6.0.1 (worked fine on 4.4.4 with no issues for almost 2 years). Within 1 week of being on 6.0.1 it started lagging then stuck in the boot loop. I tried flashing with odin back to 4.4.4 and 5.0 and now have it back on 6.0.1 all with the same boot loop errors. It's like once the 6.0.1 update is installed it 'breaks' the phone. I've discovered by monitoring the CPU temps with cpu-z that it always has to do with the temp. Once it hits around 90C it will reboot.

Only solution that seems to work 90% of the time is to have wakelock set to 4 and now also setting the permission on the touchwiz apps as described above seems to drop the temp to mid to low 40's. (as a side note as soon as I installed Go Launcher it jumped by 10C, so I've since uninstalled that and now just run on stock touchwiz - need to minimize anything that adds temp to your CPU)

After talking to the samsung reps they believe "it's a hardware issue" and of course I'm not covered under warranty now. If it wasn’t' for having a gear S I would get a nexus 6p….

......although If Google put something into the update that overheats their competitors phones their stock/sales might go up….?
[Galaxy Note 4 Q&A, Help & Troubleshooting] bowchaser:
My Note 4 developed a whole bunch of issues recently - random freezing, rebooting, charging issues, can't turn on unless I take the battery out for a while, when booting goes to Samsung logo and then reboots again, ... Not rooted, running stock MM.

After installing Wake Lock it didn't restart yet (2 days now). I see a random screen flickering every once in a while.

Those who went back to stock KK after MM... Is it worth going back? Some people say once you upgrade to MM it will keep resetting no matter what stock rom you put after.

Thank you for the information.

On Kitkat I had no problems but on MM their are days with no reboot and on the other days I have one/two reboot every hour. Mostly in deep sleep or when an app write something on external SD (Amazon video offline download).

One other question to all who uses an external SD. When I restart my note it takes up to 20 min on “...is verified“ until my sd card (128GB, Samsung Evo+) is shown in settings...is this normal?

:)
[Galaxy Note 4 Q&A, Help & Troubleshooting] Kinsman-UK:
No, definitely not - 64Gb Samsung Pro here, on a N910C. SD card is always ready for use immediately after boot. Maybe you should reformat, or try another card. Is your device and card encrypted?
[Galaxy Note 4 Q&A, Help & Troubleshooting] Sizilianer42:
The card is a new on and I formatted with the note 4...not on pc. Today I will try a 64GB Samsung Evo. I don't know if it depends on card size. Official support for the European note 4 is only 64GB external card. Card and phone are not encrypted and I have the problem since the MM update :/

It's also possible that the update crashed or that the card slot has a damage...but the phone detects the card every time... :/

I have the freeze/lag/reboot issue on my att note4. My note 4 was great until about 3 weeks ago when I updated to MM. I also have a 256GB Samsung card in the note 4 from Samsung from buying the note 7. When I have the sd card out of the n4 the phone is perfectly fine just like it was before the MM update. When the card in in the phone it constantly lags. So I backed up my sd card on a laptop and then formatted the sd card and only added my pictures to the sd card and put the sd card back into my n4 and sure enough it started freezing again. I have wake lock installed also, but that doesn't help. I'm so confused why the sd card is causing lags with MM.
[Galaxy Note 4 Q&A, Help & Troubleshooting] rsduarte:
I Have a note 4 Edge to, and i notice that it was doing 3 to 4 restart daily. But was very quick restarts, even in the android system the connected time continue to increase and not starting from zero (In a normal reboot the up time will start from zero again).

I tried every recommendations mentioned in this topic but it keep restarting once in a while. I just notice the restart because after that to enter I had to put the password protected (Saying something like "after a restart is not possible to unlock device with fingerprint, insert your password).

Well, since last Friday the device is working without any restart (noticed by me). What changed? I notice the probably the fault was on 6.0.1 / samsung/ FingerPrint detection. I just turned the FIngerprint of, I have now a normal design password to unlock the device and... Voilá! Working again without any problem!

Hope it will help someone with the same problem.
