I'm bone stock, no root and have recently applied the L720VPUFNAE update. Since taking the update, the phone has had nothing but problems. When awakening 50% of the time I will get nothing but a black screen and will have to hard boot the phone. The other 50% of the time, it's extremely slow to accept my unlock code. Half of my home screen shortcuts are gone, just disappeared. Battery life is terrible, just a few hours of life. I've browsed here for solutions and have seen some people having similar issues on other sites, but no solutions. Is there a way to force the update again to see if that fixes it? Any other solutions aside from factory reset? Often times the phone will ring and I cannot even answer it because it won't wake up properly!
I would suggest to factory reset the phone then proceed to Odin NAE tar that is available in the development section. Of course back up important things just to be sure. I had bad battery life for a few days. Until I discovered that it was clash of clans that was draining my battery. On Wi-Fi with the screen off it would drain about 4% since using greenify on it my battery now doesn't drains 0-1% under the same circumstances. You might have a rouge app that is draining your juice.

I am having these same exact issues. Really don't want to do a factory wipe if possible, but I am starting to think I may have to do it.
Also, the wifi issues have not been fixed with this release.
Anyone using anything like Juice Defender since the update -- is it helping with battery drain?

What Wi-Fi issues. So far I haven't ran into a single one on unrooted.
try greenify it works wonders.

After the last update to 4.3 a few months back, I also had some serious issues which were only solved by a factory reset. I hate the thought of doing it again, it's so much work getting all the tweaks and settings back the way they were. But it appears that may be my only option. Each OTA patch Samsung has released has been a disaster, it's getting to the point where HTC might be back on the menu for me.
Bit dramatic there. If a factory reset fixes it there's nothing wrong with the update which you might have to do with an htc update also.
i can agree on the insane batt drain but other then tbat im error free.. the batt drops even while on the 1.5amp charger..

As a followup to my own post, here's what I tried to fix it:
1 - A full factory reset with data wipe. Unsuccessful.
2 - A visit to the Sprint Store to have them nuke & pave the device to complete stock (it already was, but hey). Unsuccessful.
3 - Remove the Exchange Active Sync account. Successful.
To me this indicates a severe issue with the stock EAS client that comes with Kit Kat. If you are having similar problems to me, where the lock screen takes 20 seconds to appear, battery drain is enormous and the phone has problems "waking up" from screen power-off, try removing your Exchange account.
I might have to give something like Touchdown a try, I'm open to suggestions of a less costly alternative though.
once i remove it.....what will become unusable??

Sent from my SPH-L720 using xda app-developers app
I don't know if it's the same for you, but I had the native Exchange Active Sync email configured on my device with a enforced PIN lock. When my EAS account was configured under KitKat, the PIN lock screen had all sorts of issues, the device would get hot and battery life would go out the window. I deleted the EAS account, not the service.
Since then, I switched to Nine for my Exchange mail and the problem is completely gone. To make sure I configured the native app and deleted it a number of times. Each time the native EAS email was configured and the lock screen set, the phone crapped out. Nine enforces the same PIN lock policy, however my lock screen no longer freezes and kills battery. I am using "device security" with Nine, not "account security".
I'm honestly surprised to be the only one to experience this after combing through this and other forums. It means there's either something unique about my phone hardware/config or my Exchange server that causes the PIN lock screen to crap out. I don't have any lock screen widgets active.
My wife has a bone stock S4 with the same problems. We flashed the stock kitkat tar with odin and wiped data which didn't help. She doesnt use exchange, just gmail. Im trying to convince her to move to a gsm provider and get a nexus. Im Effing done with sprints garbage network and garbage bloated roms. Any suggestions before I set this phone on fire?

So I had the same problem and this drove me crazy. I tried wiping Cache from OS, from Home key+Up volume+power, I tried a factory reset, I event tried applying the 4.4.2 patch via ODIN. I tried removing the lock screen and company email. The problem kept coming back.
Today however I brainstormed with a coworker who also has a working 4.4.2 S4 on ATT. After comparing settings for the lock screen we noticed the new swipe option and turned that on. What a bad move... that locked the phone up hard to the point I kept getting "com.android.systemui" stopped responding. I had no choice but to pull the battery and reset a few times and it didn't fix the problem. At last I had the idea to pull the SD card and boot the phone. That worked!
Everything worked exactly as snappy as it did with 4.3, so I rebooted a few times, got some texts, turned on the lock screen in order of swipe, and then PIN. With everything working I turned off the lock screen and put the SD card back in.
No problems....
rebooted
No problems...
turned back on the lock screen and all has been running well.
I'll report back if it slows down in a few days but at this point I've come to the conclusion that this problem has to do with the SD card. My thought is the Symbolic link which guides the OS to the SD card stay in the system even after the reset or upon reapplying a Play app. The removal and boot without the card removed the symbolic link and reset all the ExStorage to the new Kernel/OS version.
Hope this helps anyone suffering the same problems!!
Just wanted to throw my 2 pennies of experience in the ring. I'm on MF9 Bootloader and just recently moved to an NAE rom and kernel. I at first left my modem MF9, and everything was fine. Yesterday I flashed NAE modem and thats when the lag/black screen/CPU continuously working began. I cleared cache and Dalvik and still no fix. Being that I had just flashed the modem, I flashed back to MF9 modem and the issues went away. I then repeated the NAE modem flash and same issues came back. I'm back on MF9 modem and back to normal so far. I will also say that after flashing modems, there is a pop-up at boot that says something about android updating(no this is not the normal message when you clear dalvik). I dont know what the exact issue is, but for now I'm going to stick with MF9 modem.
Edit - Before anyone asks, I did check the MD5 of the NAE modem. That was my first thought is maybe a bad download.
Did you end up fixing your issue? I tried the SD card thing and it seemed good for 12 hours or so and then started having issues again. Thanks.

Same thing happened to my S4. Moved to an NAE ROM and also installed the NAE firmware. Could not figure out why this slow down was happening. After some googling I ran across something that suggested installing the MF9 firmware again. After flashing 3 times to actually get it to stick, my issues went away.
I don't understand why some phones don't like the NAE firmware, but I just chalk it up to technology is weird sometimes and have accepted it. It works fine and good signal with the MF9 firmware, so I'm not worried about getting NAE to work.
I did just notice about 3 days ago that my battery life was dropping a lot without even using it. This is on stock unroofed NAE. I used to average 15 hours with 3.5hrs screen time. Now I am lucky if I can get 7 hours with 2 hours of screen time. It might be my phone so I might go to A sprint store to see if my battery is failing. It isn't a rouge app that is affecting it , not low signal( have an airwave). I go.to sleep with 90% and wake up 6 hours later with around 50% or less.

Well my wifi broke flashing modem to MF9... guess I'll need to flash back.
Ive had a note 3 now for around 2 weeks, one thing that is really annoying me is the fact that my clock (both screen widgets and system clock) keep changing randomly by itself. It can jump 6 hours or 1 hour it doesnt seem to be the same every time. I have tried multiple factory resets through the setting option and also through the phones recovery menu. I have cleared cache on the clock app and the phones cache from the recovery menu, still no avail. I have been looking and seen there are others that have experienced this problem but i cannot for the life of me find a fix that doesnt involve rooting my phone. I use alot of apps that will not be compatible with a rooted device.
I have tried auto time and manual time, When its wrong if i go into airplane mode and back out it normally corrects itself for a few hours but then changes again. Sometimes i need to reboot the phone to correct the time.
Can anybody help me out??
Have you tried if the same thing happens without the SIMcard inserted? I remember a case where someone had this and the cause was a faulty SIM.

Have you turned GPS off? There were a few complaints the GPS would update and hink it was somewhere else in the world causing the time to change and people to miss alarms that had been set....
Tried with GPS still nothing
I had this issue on my note 2, jb 4.3.
And was the same with my note 3 on jb 4.3.
On my note 2 is still like that until now. But my note 3 the issue has gone after upgrade to KK.

Hi,
Does your Note restart itself? Mine sits in Flip Wallet and today it was just lying on desk not being used. And suddenly it just restarted? Do you have similar problems? Any possible solutions?
Have a look at Settings > Accessibility > Dexterity and interaction, check if "Air wake up" is on.
If so, you've got your answer.
Edit: Oops ! Didn't read closely enough, RESTART, not turning on suddenly. So just ignore the above.
Had the same problem, the phone restarted itself 3-4 times a day and 3-4 more at night. It drove me nuts. Returned the phone to the store forgot about that problem. There are many people who have that annoying problem.

Returned and got replaced the unit? Or just returned and turned to other model?
How do you know that many people have this problem?
returned and stayed with my LG G PRO 2. Amazing device.
there are many reports on Google and YouTube for the same problem.
Mine used to do exactly the same when it was rooted with CF Auto Root, is your note 4 rooted? I've un-rooted and it didnt reboot since 3 weeks now. Used to reboot once or twice a day when it was rooted. Dunno what the problem is and why its related to root...
The UI just frozen and phone rebooted itself right after pressing calculator icon but the calc app never showed up...
This is the first time this happened on this device.
Yesterday my gear fit's display would not turn on while under exercise mode, the HR monitor was still activated. Forced the gear fit to reboot and the wallpaper reverted to the default by itself.
Looks like this phone needs a major update to Android 5.0.
Oh and by the way, the phone is stock and official, Model number is SM-N910G.

Okay, this is what i did, fortunately i installed a custom rom on my SM-N910P (sprint, snapdragon) called enhanced rom, this rom brought with it an app called Kernel Adiutor, i opened and saw only 2 out of 4 cores were in use, so i turned them all 4 on and the phone stopped acting like that, it was instant, so if any of you has a rooted device and this problem just get the app and turn on all the cores in the CPU tab inside the app
The first one fixing it
This is my first post on this forum. I searched around here for a solution, didn't really find one matching my problem. I am not a phone wizard or anything like that either. So I'll try my best explaining my problem.
First things first:
Phone: Note 4
Model #: SM-N910T
Android Version: 5.1.1
Rom: Stock Rom
Rooted: Rooted Once and used a custom Stock T Mobile Rom Once.
Here's the ROM I used at the time: http://forum.xda-developers.com/not...10tuvu1cog2-debloated-deodexed-stock-t3175406
Recently I So recently my phone out of the blue started lagging, freezing, and restarting itself. I didn't download any applications or anything like that for it to freeze up. I was currently then on the custom ROM I have mentioned above and it was the updated version. I have tried everything to my knowledge to try and fix the problem. I have tried going back to stock T mobile ROM (currently on stock rom now) through odin and stuff. After all that, it was still lagging, freezing, and restarting etc... Ran it through safe mode and the only problem in safe mode is that the lag is gone, but the restart is still there. Running in safe mode, if I would turn the screen off and back on to unlock my phone, there would be like 40% chance that it would restart after unlocking the phone and the phone would just restart normally. Rarely, whenever my phone would attempt to restart.. I would get a "Could not boot normally" message along with couples codes below and the image of android guy. Then I would have to take my battery out and attempt to restart the phone once again.. I've wiped the cache and everything in recovery mode, nothing helps at all. Also, the phone is in perfect condition. Hasn't been dropped, cracked, no water damage, or anything like that.
This place is my only hope to fix my phone before I will go out to buy another phone from the carrier.
Thank you all for taking your time to help me

Well I already got rid of my note 4 unfortunately before anyone could help me here so I had to upgrade my phone to note 5 and return note 4. While I still had my note 4, I realized something weird. While the phone was lagging and crashing etc.. When I had it plugged in for charge it would work perfectly fine. No lag, it wouldn't freeze up or restart (had it running perfect for 7 hours). It was like my phone was brand new again. As soon as I unplugged it from the charger, few minutes in and it was back to restarting and all that. I never knew why it did that.
Anyone know why this mightve happened?
Might be the battery though
I thought that too. I tried my brothers note 4 battery for awhile and it worked for a little bit and then it started doing the same thing even on his battery. Shrugs.

In the COH update iteration there is an annoying bug that affect fingerprint.
The bug causing the phone to restart, lagging & closing all apps randomly when the fingerprint is set.
May be this one is also the same.
Try to disable all fingerprint related settings.

Hi there,
So my galaxy note 4 is having some serious problems for the last couple of days and it's really starting to bother me. I've tried doing everything I can find online so far but to no avail I've had no luck at all. Basically, my phone constantly keeps freezing and restarting. It will crash for quite a period of time then restart itself, crash and restart. It probably crashes and freezes about 80-90 times a day? More if I'm trying to use it of course (It also resets itself when not using it).
I've tried everything, bought a replacement (genuine) battery and not fixed it. Got to the point where I seen online about doing a factory reset so I backed everything up to my computer, started the factory reset and when I was going through the setup of logging into google and samsung account, it continues to crash and freeze all over again. (It crashed & restarted whilst retrieving my apps from google, thus I had to reinstall my apps again manually after I finally got it setup again).
To make matters worse, I cancelled the insurance cover last month and only a few days ago this started happening. I've not dropped the phone or damaged it in anyway, screen is completely perfect too. It just constantly crashes and restarts on it's own. Get a phone call and it crashes, using google maps, crash. It's beyond unusable now. I still have 4 months left of the contract before I'm due an upgrade and I really don't think it will last me that long.
Can someone PLEASE help? Suggestions would be so helpful!!!
Thank you!
P.S Phone isn't rooted, only using Nova Launcher prime.

"Kernal Panic" with some information on the top. This only has happened the one time and hasn't happened since. Took the battery out and restarted again...

Still happening and it's driving me insane, It won't last me until the end of my contract (January)
Its rebooting 80-90 times in ONE day? Good god! Have the phone turned off then. Unnecessary pressure is being put on the phone mate!
Factory Reset isn't going to solve it anyway, its for tiny problems. Your system is somehow messed up badly.
Do what the above member said. Flash a stock ROM via Odin. But before that you need to completely wipe the phone. To completely wipe you need a custom recovery like TWRP. So flash it now, root the phone, then reboot into TWRP and use the Advanced Wipe section to wipe everything (external SD not needed), then reboot the phone in Download mode, and flash the latest stock ROM via Odin.
You are now part of a large group of us having the same issues. Several things have been tried. One thought is that the motherboard is faulty. Replacing it would be expensive. Download the app "wake lock" and set it to partial_wake_lock. Don't ask me why it works, but it does. Apparently the phone goes nuts when the screen tries to go off, the partial lock keeps it from crashing. That makes the phone usable, hopefully a permanent solution will become available. ;( The only time it goes nutty again is if the battery runs down and when I restart, the app is not running. Going back to the back and setting it to partial has allowed me to play games, etc for extended periods of time and no problems. It shouldn't be that way, and I really suspect the marshmallow update and then security update screwed it up, it was fine before that.

Which version is your note 4? verizon? att? tmobile? sprint? etc united states variant? other country? This helps find out if others that are having the same problem are on the same setup as you and more importantly tells me if I'm likely to have a problem with mine getting ready to come. :laugh:

80-90 times in one day is probably being generous. I've not actually counted how many times it restarts but If I need to use my phone I can guarantee it will be restarting a couple of times. Driving using navigation *Crashes* Inbound phone call *Crashes* get text message *crashes* all followed by the phone restarting. Practically unusable.

I'm gonna give this a go and hopefully it'll help! Thanks for the advice. Funnily enough, for a couple of months the phone has been prevented from the screen going off. I get a text or a notification and the screen would stay on until I hit the power button to turn it back off. Get a text in the middle of the night and I'd wake up to a boiling hot phone the next day, almost too hot to even keep in the hands. This literally frustrated me beyond belief and had to get a new battery and all sorts of complications. Also you mention the android update which made me think, I NEVER had this issue before I installed the security update for 6.0.1 - I put my money on something really stupid that's sincerely knackered my phone for certain!
While upgrading a phone, especially for major upgrades like from LP to MM, OTA method should always be avoided. You MUST do a clean flash of the ROM, otherwise you are bound to have problems. 80% of time people complain because they didn't flash the ROM cleanly, so whatever you want to do now, do it, but if it doesn't solve it (very likely it won't), then kindly flash the ROM via Odin after a full wipe. And if even that doesn't solve it then its hardware.

80-90 times in one day is probably being generous. I've not actually counted how many times it restarts but If I need to use my phone I can guarantee it will be restarting a couple of times. Driving using navigation *Crashes* Inbound phone call *Crashes* get text message *crashes* all followed by the phone restarting. Practically unusable.

I'm gonna give this a go and hopefully it'll help! Thanks for the advice. Funnily enough, for a couple of months the phone has been prevented from the screen going off. I get a text or a notification and the screen would stay on until I hit the power button to turn it back off. Get a text in the middle of the night and I'd wake up to a boiling hot phone the next day, almost too hot to even keep in the hands. This literally frustrated me beyond belief and had to get a new battery and all sorts of complications.

Thanks for letting me know your version. Hopefully it wont affect mine since mine is US Verizon. But out of curiosity have you checked for even the slightest sticky button? I've had phones where a button started to get tacky and would cause it to keep the screen on or go on and off like what you're saying. May not even feel like a sticky button. Do they all click very responsive? or do any feel like they have a dull thud experience?

The volume rocker and power button feel really loose but this isn't really something new. Something I have noticed is when I take the cover off the back, the battery barely stays in itself. If holding screen upwards and battery cover off then It doesn't hold the battery which made me possibly think that perhaps the battery does not situate properly and doesn't deliver enough power (or too much) but this was just one of my theories into why the hell my phone is acting this way.
Edit:
Forgot to add I'm running the security patch 01/08/2016

Are you able to wedge a folded small piece of paper between the bottom edge of the battery and the phone to make the battery fit tighter? I mean it's not good to have a loose battery. But I can't see how that would cause the screen to stay on. If anything I would think it would cause the phone to shut off or reboot.

Let me know how it goes. There are other threads about same issue. Most of us have tried reflashing, wiping everything, custom roms, going back to stock, trying to downgrade, taking out the sim card, taking out the sd card, not having both in at same time, brand new battery, I think even putting the battery in the freezer momentarily, etc. etc. Nobody seems to have had any real luck with it, except those who were under warranty and got a new phone, or are capable and wiling to exchange some hardware. I just find it odd that it happened all of a sudden after updates and recently to many people.. Still, I keep coming here hoping someone will have great news. Mine started with marshmallow, but definitely got worse with the security update.

why don't you reflash you device with supported PIT file and stock F.W ?

Hi there,
So my galaxy note 4 is having some serious problems for the last couple of days and it's really starting to bother me. I've tried doing everything I can find online so far but to no avail I've had no luck at all. Basically, my phone constantly keeps freezing and restarting. It will crash for quite a period of time then restart itself, crash and restart. It probably crashes and freezes about 80-90 times a day? More if I'm trying to use it of course (It also resets itself when not using it).
I've tried everything, bought a replacement (genuine) battery and not fixed it. Got to the point where I seen online about doing a factory reset so I backed everything up to my computer, started the factory reset and when I was going through the setup of logging into google and samsung account, it continues to crash and freeze all over again. (It crashed & restarted whilst retrieving my apps from google, thus I had to reinstall my apps again manually after I finally got it setup again).
To make matters worse, I cancelled the insurance cover last month and only a few days ago this started happening. I've not dropped the phone or damaged it in anyway, screen is completely perfect too. It just constantly crashes and restarts on it's own. Get a phone call and it crashes, using google maps, crash. It's beyond unusable now. I still have 4 months left of the contract before I'm due an upgrade and I really don't think it will last me that long.
Can someone PLEASE help? Suggestions would be so helpful!!!
Thank you!
P.S Phone isn't rooted, only using Nova Launcher prime.

Aside from the previously proposed wake lock solution, members in the T-Mobile Note 4 threads have experienced limited success with a downgrade to LP from MM.
From my reading, these issues seem to be common across all Snapdragon models, not to say it Exynos is excluded (I don't frequent Exynos threads).

I tried that and it didn't work for me. The only surefire solution is a replacement device, but even then there's no guarantee the device won't start acting up in the future.
pls help stuck in download mode
this is the issue I'm getting...I did a complete data wipe using twrp...now stuck on this screen...cant even push files...device not recognized in adb or fastboot mode....
what to do...??

Well a new motherboard was the only thing that fixed it for me, replaced under the 2 year warranty but I had to wait a while for parts. What is interesting is that the phone is much faster, the battery life much better than when it was new. Also it now barely gets warm using google maps - before it got quite hot. It would be very interesting to find out what percentage of Note 4's have been going down with is problem - mine was a fairly early one - was Samsung rushing to beat Apple two years ago and a bad batch of parts used? I don't know -we need some answers on what is the problem to be sure.
Just a personal experience and thus advice, please don't keep flashing bunch of stuffs every other day. The more your eMMC gets used more chance of your phone getting messed up. This is how my Note 3 died, kept flashing this and that, and did the same on Note 4 too, but have now stopped. I don't know whether there's an endurance rating on these eMMCs used or not but this is what I think, I could be wrong, please quote me in that case.

Wow, that sounds promising. I'm sending mine for replacement, and although I'm not getting a new MB installed, hopefully the incoming unit will be similar in performance to yours.

Your reasoning sounds plausible, but my phone suffered similar issues and I only flashed my unit 2-3 times in the 14 months I had it.
