HELP Phone keeps freezing after 4.4.2 update - Galaxy Note 3 Q&A, Help & Troubleshooting

Help, this morning when I did an OTA update to the new 4.4.2 it installed fine. But after re-starting, the phone keeps on freezing and not working properly. The screen goes blank and I have to hold the power button for about 8-9 seconds for the phone to reset. Once it goes in, it freezes again. The notification panel no longer works and in fact causes the phone to totally freeze. HELP!!! I have been using Iphones for so long and never have any updates had these sorts of problems. Please tell me what I can do.

I have the same problem with my German Vodafone Galaxy Note 3 since the update to Android 4.4.2 (Build KOT49H.N9005XXUENA6).
The phone completely freezes every couple of hours and can only be restarted with power button helt for 10 seconds.
First I tried a factory reset, which didn´d help.
Next I swapped the phone via Vodafone - but the new device also freezes.
Then I started to uninstall several apps, which didn´t help anything.
Uninstalling my MicroSD-Card (Sandisk Ultra 64 GB) seemed to help a Little bit, but finally the phone started freezing again.
It´s really annoying - Samsung told me to swap the device once again, but I don´t believe, this will help.
I now uninstalled my original S-View-Cover - maybe there´s a bug even with original accessories.
Does anyone else experience similar problems?

It is possible that it's Vodafone's software causing the glitch. You could, providing your device is sim unlocked try the Polish firmware and see. You can do it without tripping knox also.

no don't use any cover

Same problem here. Also thought it would be the s-view cover, but today I found out that it wasn't the problem . Dryving me nuts.
I have the Dutch phone which is totally original. Problems started after update. Freezes followed by reboots.

Same problem without using S-View cover. It happened only after kitkat upgrade. However it will back to normal itself after leave it alone for 1-2 minutes.

Any more info about this? Did you all use OTA update? I have a Dutch n3 too but I'm not updating just yet.

Here´s what I found out so far:
-> This ist most probably a software problem, as my device was swapped already and still has the same problem.
-> The problem occurred after OTA update to Android 4.4.2 (Build KOT49H.N9005XXUENA6 [German vodafone device]).
-> System often hangs and finally freezes every couple of hours.
-> The device didn´t freeze for 24h after removing the S-View-Cover, but still is hanging sometimes.

I talked to Vodafone this morning and they told me, that this is an incompatibility problem between the LTE-net and the new Note-3-firmware. They suggested to disable LTE-mode on the phone. Alternatively they offered me to swap the phone again and then not to update to 4.4.2.
I disabled LTE now and will report, if it helps.

I'm using a Dutch provider which doesn't support LTE. Despite of that, my phone still freezes and reboots every few hours.
Can you tell us how you disabled LTE? Although I won't think it works, I still want to try because this issue is driving me nuts.

Just to shed some light on the "cover suspect": for me, my unofficial cover was found guilty. 100% sure. Tried everything, then took out the cover, made a hard reset, and the freezing thing was gone.
Now, have other issues, but no freezing at all.
N9005 updated to kitkat via ota. not rooted (yet).

Glad to hear it worked out for you. Unfortunately for me it didn't work. Changed cover back to the normal backcover that came with the device, but still the same issues.

My device froze again yesterday, inspite of
- microSD staying removed
- S-View - Cover staying removed
- LTE staying disabled.
It's really annoying, I think I will swap the phone again through Vodafone and stay on Android 4.3.

Still the same issues. Waiting till Samsung rolls out the first fix. If it's not fixed after that, I want a replacement.

HD2 Bug: No Standby mode, screen always on

Hello
My HD2 Worked well for a long time, but now everytime I press the "sleep" key it turns off for half a second then turns back on and proudly displays the lockscreen without me pressing anything. There is no way to turn the screen off and go in standby mode anymore.
Obviously the battery drains so much faster from not being able to have the screen off and this silly problem actually makes the phone unusable
I flashed a few roms using HardSPL and now HSPL2. I'm currently running Artemis 11.0, the problem appeared may days after flashing while using Artemis ROM 9.0. A hard reset seemed to fix it but the problem reappeared. Today flashing 11.0 only solved the problem at first boot.
Anyone had that before? Not sure if it's software/rom related or not anymore. HELP
As far as Ive seen, its only you an me who have had this problem so far.
Honestly, Im relieved to see someone else with this problem.
I had exactly as you described, but using Axlor roms.
It worked fine for 1/2months, then all of a suddon the screen backlight wouldnt go off, but a reset fixed it.
But it got worse and worse.
Now nothing will work...
Ive taken everything back to stock, and i mean EVERYTHING! Not a single app installed.
And I still have this problem. I've tried it all.
I think its a warrenty job....
EDIT:
I also noticed the backlight will go off fine when the phone is charging, is that the same for you?
I just sent the phone off to Tmob today, to see if they can fix/replace it.
I'll keep you informed.
Same problem. Was running fine on stock ROM 1.66 then backlight did not dim and would not go into standby. Put into standby, screen goes off then straight back on to the lock screen. Since then have had other problems at boot, sometimes it locks on HTC white screen needing battery removal, sometimes launches straight into Navipanel and will not exit, HTC sense homescreen sometimes launches in landscape and will not go into normal portrait mode. Reflashed with different ROM's same symptoms persist so have returned to Vodafone UK under warranty, fingers crossed.
i've had this on early versions of the rom i use, the chef fixed it, making me think its the software, not your phone.
I experienced this issue when I minimised a game called virtual pool. Closing it in task manager would then allow me to permanently make the phone sleep.

How come Ive still got the problem after reflashing several times and taking everything back to exactly as it came from the box?

I too have had the navi panel problem.
Im praying they fix mine under warrenty
Yes the problem is exactly what you describe, hard reset and flashing to a stock rom doesn t fix it with no programm running in the background
Navipanel seems to be on randomly sometimes so can I guess it could be related.
I found a fix, after starting the phone, plugging and unplugging the usb cable to the phone WHILE THE SCREEN IS ON fixes it but only until the next restart
Considering sending it for warranty now.
Thanks for replies! If anybody knows more let us know
Update re standby problem
Got my phone back from Vodafone UK today. Was advised software corrupted and that they had reflashed and it had been fully tested and was now working fine.
On power up (even without SD card or SIM) it had exactly the same fault as before, when put into sleep mode the screen comes back on after about 1 second.
I tried the plug in and remove USB lead fix and this also works for me until the next restart so it would seem that this must be a hardware problem.

Thanks for this workaround. Now with the urgency gone hopefully somebody finds a lasting solution without the need of sending it in..
I have same problem guys after 4 months using. ...and my HD2 is unusable with no standby. I mean battery gets weak during 2-3 hours. Whats your guess guys is it software problem. Cause Im afraid of this is hardware prob because after reset goes my device in wrong state.
Help!
Sadly I'm running into this same error with my t-mobile hd2....getting serious power drain...can anyone confirm if the task 29 helped at all? Mine won't stay off for more than 30 seconds.
** Found out the google easy sms beta app I was running had a service which was causing the app to come out of standby...uninstalling this app cured the problem.
For me, it was a sd slot problem. When i removed the sd card, phone always waked up after 0.5 seconds, and card was detected as bad.
Now the SD slot was changed (under guarranty) and it work fine, no wake up if sd slot is empty.
Any update on this? My HD2 starting doing this today as well
And I have no usb cable at work to 'trick' it. The only option is to pull the battery which I don't want to do. This is ridiculous. Am I going to have to hard-reset the damn thing to fix it?
FYI I didn't do *ANYTHING* to my phone in a couple of weeks (no new apps, etc.) and it started doing this out of the blue.
You hit the red 'end call' button and it goes black..then comes right back on.
The odd thing is it *thinks* its plugged in because the only screen setting I can get it to acknoweldge is the 'backlight level when charging'. So somehow my phone thinks its plugged in even though my only usb cable is back home.
Grrr. No registry tweaks or temp files I can delete to reset this behavior?

Freezes overnight with my I9505 Galaxy S4

Hi Guys,
i got freezes when i charge it overnight (its connected to the original charger the whole night). I only can do a hard reset to use my device again because the touch-screen doesnt work then. This is very annoying because i use my device with Alarm to get up in the morning.
I already did a few clean installs (Cyanogenod Snapshots and Danvdh's Google Edition), wiped all caches and formated all data and caches aswell. I still got freezes. I get them from waking up my device (mostly in the morning between 5-6 am). All i see is a exclamation mark when i turn on the display. Then its frozen and i cant anything.
I already tried a few Modems and Kernels to test, but still freezes...
I use Modem I9505XXUGNK4 atm.
Any ideas ??? I really Need help with this !!!
Thanks

Have you tried the new 5.0 gpe from danvh? There was an issue with the charging animation and reboots.
yes, i got Dan's 5.0 gpe at the moment 12.17.2014
Dumb question, did you clear /system in between flashes as well?
Yes, i formated System and Cache + i wiped everything too
You should flash the latest stock firmware and see if the issue persists. If yes, try a different charger. If the problem still persists, I think it's a hardware problem. Probably battery or motherboard.
The Problem is only between 5-6 am. The whole day i got no Problems Should be a Problem with my Router maybe ?
i got no resets in my Settings there. maybe my Provider is doing a reset every day between 5-6 am and my device freezes then. i could try airplane mode too to test, right ?
I bought a new charger and battery today (both original). Maybe thats the problem.
i got News guys, i turned off wifi overnight an didnt plugged the charger to my device this night. No freeze !!! Yay !!!
So it only could be, charger, battery or Wifi, right ?
ok, i had a freeze at work a while ago. but i got no wifi or charger there... now i dont know what to do
Does it behave like this?:
You pick up the phone (it is in deepsleep),try to turn the screen on,it goes on,you try to unlock the screen and it just stops reacting to anything and turns the screen off after 20-30seconds?

can`t help you with that,hope you have luck and fix it
Same problem
Hy people, i have the same problem, but is not a specific hour when it freez, yesterday i picked up the phone and when i unlocked the screen, it freezed, but i don.t wait 30sec, i just lock/unlock it again and it work fine. The other problem was overheating..
and randomly restarting but i think i fixed it with a factory reset. What i want to tell now is that i installed "Root booster" before all these problemsc ocured. After it played with the kernel, do you all thing it might not restored the original settings? My phone is randomly heating sice i installed that **** on it...(even if i do factory reset)
Ps: i have a stock kernel/gt_505
Or the battery is guilty? It's draing pretty fast, after a day of use i put it to charge

Hy, i haved the same problem, but what i did yesterday solved that. I hope this steps will help you:
1. Enter in Recovery Mode and select wipe data/factory reset
2. Clear cache partition
3. Go in Settings/More/App Manager and search for Touchwiz Home
4. Force stop then Clear data
5. Withouth exit from settings, restart your phone
6. When phone is on, screen will be black and will ask you witch program you wanna use, select Touchwiz home then press "always"
After this steps, i solved the problem for my phone, but another thing i done after that is delete all knox files with Titanium backup.
I hope this steps myght help you.
Thanks guys, but i got a nexus 5 now. Bye Samsung. Thanks anyway for help.

[Q] Singapore Note 4 keeps freezing and restarting

My Note4 was updated to Lollipop about 2 weeks ago and it was running ok until 3 days ago where it keeps on restarting, freezing up, not responsive etc.
The last application that I installed was "FACEBOOK GROUP" but I'm sure this isn't the problem because of the factory reset as explained below.
I have done a factory reset, but I reinstalled all the applications (except Facebook Group), but the problem still persists. It even restarting without it's being touched. Per day, it could restart up to 15 times.
Most of the problem appears when the phone goes into an idle state and won't turn on unless I do a battery pull (like Blackberry).
But sometimes it would respond from the idle state after a 20-30 seconds.
I did find an article that the motion and gestures are causing the unresponsive issue, in which I have followed and disabled all the motion and gestures, this doesn't help. Problem persists.
I have talked to the Samsung Tech support and they told me that I would have to bring it to the service center in Singapore (I live in Jakarta) and they would need to diagnose it. I did mentioned that I want a new phone but they said that they don't have exchange policy. This is really bad because Iphone has an exchange policy, why doesn't Samsung have one too??
Anyone in Singapore maybe have the same issue? or have a knowledge about the exchange policy?
Have you tried uninstalling Facebook Group from your Note 4? It seems to me that the Facebook Group App must be causing some sort of problem with your Note 4.

UPDATE 1 :
I uninstalled DU Speed Booster, and the problem seems to be better, but still hangs after unplugging from charger.
Does anyone use DU Speed Booster with Lollipop?

OK, seems like DU Speed Booster may have messed with the system settings of your phone somehow. Are you using the stock firmware that came with your Note 4?

Yes sir, it is the stock rom.. and it's not rooted. Still original except that it has been updated to Lollipop.
Uninstalling DU Speed Booster seems to make it a little better, but occasionally it still freezes and restart but it's not as many times as before.
If the system setting has been messed up, then I will do another hard reset tonight and see if that would fix the issue. I'm tired of waiting for the phone to come alive after idle or when it restarts by itself.
UPDATE 2 :
I did a factory reset last night and left it to sleep while it was updating stock applications (I have not installed any of my application).
This morning when I woke up. I couldn't turn on the phone. It was frozen and it has a solid red LED light on the top left. This happens quite frequently before too. So I'm not sure what the issue is. Btw, my note 4 is the first batch. Bought it when it first came out.
I had to take the battery out and started the update again.
Then it got restarted when I tried to swipe my finger to enter the homepage.
Why doesn't Samsung give an exchange policy? their rival Apple does..
Yeah, I think you need to return your device to Samsung for repairs. As for why Samsung doesn't have a exchange policy, because retailer's tend to have a exchange policy where if they can't fix your device they will replace it with another one. Since retailer's give you a 1 year standard retailer's warranty with the purchase of any electronic device. Apple has a exchange policy, because as well as being a device manufacturer they are also a retailer for their own devices.
My Note 4 has been a lot better since I reseated the SD Card. I did that before too.
I'm starting to think that my SD Card was not reseated properly causing the system to hang / freeze.
As of now, I think the culprit is the SD Card.. I will monitor and update again.
I think I posted too quicky.
The problem still persists, so it is not the 'reseating' of the SD Card.
I notice though, the problem with hanging, restarting, MOSTLY occurs when the battery is less than 40%. And sometimes, it won't even start / turn on even after I take out the battery. But when it is succeeded, sometimes, it would come out with the message (shown in the attachment). Every time this comes out, I have to take out the battery and wait 30+ seconds before trying again.
I really don't know what is the problem with the phone and this phone is bought overseas. Local Samsung Store can't fix it because they don't have the base band or software.
Please note that this phone has never been dropped / root. I have taken care of it carefully.
I'm really disappointed.
It does seem like a hardware error either with the internal memory chip or the battery. You could try replacing the battery to see if that would fix the problem, I doubt that would work. But I would prefer to just send it back to Samsung for repairs as they have the equipment to fix the problem.
Alternatively you could install Kies 3 from the Samsung website onto your computer and use that to do a firmware reinstall of your Note 4 and see if that helps. If that doesn't work then you really don't have much of a choice other than sending back to Samsung for repairs.
Similar Problem
My Note 4 has locked up three times after a full charge.. I noticed a solid RED LED after the phone fully charged and attempts to turn it on are unsuccessful, it's frozen. Nothing I do can wake it up short of removing and replacing the battery. The Lollypop update was done over a month ago so I doubt that is the cause. I'm still checking things out but it has occurred to me that if this happens to the S6, what would one do if you can't remove the battery?????

Note 4 (T-Mobile) Lag, Freeze, Crashes, Restarts.

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.

I never used finger print scanning on my Note 4. Always disabled.

Nexus 4 screen freezes randomly, no reaction when touching.

Hi everyone!
So I just had this problem after I woke up yesterday. I googled a lot but only found similiar problems.
Let me tell you what happened chronologically:
After turning the phone on in the morning it started updating apps as if I was doing a firmware update: "updating apps 1 of 135" etc. Note that my nexus was already running on 5.1.1 and had the latest updates installed.
Now it randomly freezes the screen on whatever screen it was before it happens and it won't respond to any touch input. This can also happen when not using the phone, then it will freeze at the lockscreen (the time freezes with it so sometimes i can see at what time it froze). Also, it loses connection with Wi-Fi as i'm using Whatsapp Desktop when i'm on my laptop and it mentions me that my phone is not connected.
The only thing that "fixes" (temporarily) it is a reboot. Now sometimes, on the lockscreen, i can just hold the power button and the pop-up comes in to turn the phone of, which i can somehow just tap on an it responds by turning the phone off. But sometimes (less frequent than the latter mentioned) the pop-up doesn't come in and holding the power button for a few secs will do the trick.
I hope I informed you all enough and my end question is: does any of you know what this is? How i can fix it or what i can do to prevent it or anything as I am hopeless. (my G3 is up for reparation so this is my sisters old phone, i had a nexus 4 myself for 2 years before the G3).
Thanks in advance!!
The best way to test it is by reformat the OS.
I positively think that it will solve the problem.
Since the phone is no longer under warranty, I guess there is no harm to install custom rom on it. They are fast and stable too.
Hope this help. Good luck.

EXACT thing happened to me too. Backup your data and hard reset from recovery. This fixed it for me
Same problem here bro, but neither custom roms or factory reset helps.... Is there anyone who has successfully solved the problem ?

Then it's time to change the screen or phone. Looks like it is a hardware issue.

I agree, your screen needs to be replaced.
