Full battery drain caused all core apps to fail, even after recharge...

Anyone have any idea what may have happened here?
I was unexpectedly away from home, but using the device quite heavily, and didn't have a method to charge the battery.
Once the battery had drained to about 3%, I switched the phone off but I ended up needing to make another call. The phone booted, but all core apps returned a force close message. Phone, Maps, Google Account, all the main stuff... Other apps would launch and function with no problem though.
Thinking it may have just been a glitch, I rebooted the phone again thinking there would still be just enough juice to allow a phone call, but while booting, the battery totally failed.
Once I had a chance to plug in the charger, all core apps continued to fail, even though the phone now had plenty of power.
Even after a battery pull, the same issues continued, rendering the phone pretty much useless. No link to Sprint, no WiFi network, nothing...
The phone is rooted with v1.5.2 RC and Fresh ROM v1.0, so lacking anything else to do, I performed a Nandroid restore from a backup made about 2 days ago and that seems to have fixed up the problem. (whew.. I did not want to resort to the RUU)
But, I just can't figure out what may have caused this odd behavior in the first place....

Are you using apps2sd?

No, I'm not using the apps2sd feature.
The lockscreen text showed "No service" and the notification bar icon showed the same. The "phone" application was the only one that would attempt to restart after being forced closed. After a second fc though, it would apparently give up.
Oh, and just remembered one other oddity.. Once booted and all force close messages removed, attempting to turn on the mobile network resulted in a hard reboot. I really didn't expect anything since there was no service link, but I was just clicking various shortcuts to see what did or didn't work.
Good part is that a Nandroid restore saved the day, so it's more of a curiosity at this point to what the root cause might have been.
I wouldn't have thought that a battery drain could have corrupted the apps or prevented the root filesystem from mounting.

You probably had too many apps installed. It's a known issue with the Hero, where having too many apps installed causes a bunch of core apps to fail to load for no apparent reason. The phone losing power just caused it to reboot, which triggers the issue.

oddly enough I've had a similar experience. it was 2 days before christmas and i was doing all my last minute shopping. heavy use of the phone caused the battery to die, so i just threw it on my car charger. it booted, but REFUSED to get any data at all (i didn't run into any fc's, however). I rebooted it 3 times and each time the issue persisted.
I was running the AOSP 2.0 build at the time, so i flashed my backup of 2.1 and everything was fine from there...

Hmm, good possibility there. Just did a count and I do have 85 apps installed.
(whoof, I had no idea the number had gotten that high. just too many useful apps for this phone.

Note 4 freezes while charging after lollipop

I tried posting this in the Sprint thread but haven't gotten any answers yet so perhaps I'll have better luck here. I pasted both posts to show the initial problem and what I did (essentially I factory reset). I'm still having the same problem where my phone will freeze while I'm charging it (about 2-3 times/week) requiring a battery pull. Anybody else seeing this problem or have suggestions on what I should try? Thanks.
-----------------------------------------------------------------
Twice this week my alarm didn't go off (luckily I set a backup today) because sometime throughout the night something happened. When I woke up the phone was frozen on the yellow Sprint Spark startup screen. I needed to pull the battery and everything started up fine. I updated to Lollipop about 2 weeks ago which is where I'm guessing the issues stem from.
Is there anything I should try other than restoring to factory and starting over? I'd prefer to not have to wipe everything from my phone but these issues are becoming problematic. I am not rooted.
Thanks.
--------------------------------------------------------------------
So I ended up doing a factory reset and while the phone certainly started running faster with better battery performance after the reset I'm still having this issue. I would say it occurs 2-3 times a week. It has only occurred overnight which is typically when I charge my phone so I'm pretty sure it is related to being left connected to the charger. The majority of the times I will wake up with a dim yellow Sprint screen and everything else frozen though occasionally the screen will be black with the led notification light red. In both situations the screen will not respond to any button pushes or holds and I need to pull the battery and then everything will start up fine.
Does anybody have any suggestions here on what I should do? I guess I can try and restore one more time and see but I don't really know why it would be different and it is certainly a pain to keep restoring the phone and losing all my settings. I definitely don't want to root now since I believe that voids the warranty and if I can't figure anything out with this I'll certainly be requesting a new phone from Sprint. Before I start dealing with Sprint though I thought I would check here first. Through all my searches on the internet I haven't seen anyone else complaining about this problem.
Thanks.

Hi there. I have a Canadian Note 4 (W8) with Bell, and I am having identical issues.
While charging over night, I find my phone stuck on "Samsung" logo, with the bubble animal still running. Holding down the power button does nothing and the only work around is the battery pull. I noticed that it also gets warm (assuming from the screen on time?)
First tried cache wipe - no fix
Factory reset - no fix
Cache wipe again - no fix
Aaaand today I came into work late

Did your issues first start after you upgraded to lollipop?

Definitely after the upgrade.
While on KitKat, it never happened (1 month ownership). But after upgrading to lollipop, it has happened 4 times (6 nights since lollipop).

Have you figured anything out with your situation? Woke up this morning to my backup alarm and the Yellow Sprint screen on my phone.
I guess I'll have to try another factory reset and if it still happens try and get a replacement. It just doesn't seem widespread enough of an issue to be a software bug with 5.0.1.

Very frustrated. I did another factory reset but the issue still plagues my device. It still only occurs once or twice a week but when I hear my old clock radio alarm in the morning I know when I look over I'll see the yellow frozen Sprint Spark screen. I am completely out of ideas and guess I will need to have it replaced under warranty. I'm hoping Sprint won't give me a hard time as this will be very hard to demonstrate.
It definitely appears to be a software issue as it never happened before I upgraded to Lollipop but there must be more to it or others would be complaining.
If anybody has ideas please let me know. Thanks.

Response to Note 4 Freeezing while charging
I have found that after turning the quick charge feature off the problem is not happening. Hopefully this is fixed in 5.1

I'm having the same issue even after turning quick charge off..def a lollipop bug, never experienced this on kk.

I know its not the BEST option, but after taking the update to lollipop, sometimes left over kitkat files can make the system poop out. Sometimes a factory reset will take care of the leftovers. But of course, then you have to set your phone up again
If you've tried this or plan to to, let us know the results.
(When i first took the update, my heartrate monitor sensor was always on, so i did a factory reset and it fixed my problem).

Solved with workaround!!!
I faced this "sleep of death" too after updating to Lollipop. I had to pull out the battery almost every time after charging. Very annoying! I noticed though that my phone never froze in my car while charging. Thinking about the difference I realised that I keep my phone awake in the car while charging using Macrodroid (which I love anyway to automise all kinds of things). I made a simple macro which keeps my phone awake while charging and another one that returns the phone to normal while on battery.
While charging: Trigger: Power Connected; Actions: Keep Device Awake enabled & Screen Off, Constraints: None
On Battery: Trigger: Power Disconnected; Actions: Keep Device Awake disabled & Screen Off, Constraints: None
Off course there are alternatives available to Macrodroid that should be able to do the same.
My problems are solved, with and without fast charging. I hope this will help some of you as well.

same problem here
Ive tried turning off fast charging option on the powersaving mode
And also tried the option on developer mode, the "keep device awake while charging"
And even flashing dofferent firmwares from sammobile through ODIN and installed custom roms. These options doesnt resolve the issues on freezing while charging..
I think turnong off your device while charging is the only option..
Im using note4 N910C..

Thanks a lot, Mate. I'm trying your workaround now. Will report later if it works on my phone. BTW, so, are you sure it is a just a system issue? Definitely, isn't a hardware problem? Did you fix it, after your post -a month ago-, installing, for example, lollipop 5.1.1 or Cyanogenmod 12.1? I'm on 5.0.1, SimpleRom V4. Of course, mi device, N910C, is rooted.
Thanks again.

With lollipop 5.1.1 the problem is solved for me, even without this workaround.

I'm having similar issues as you guys. I found out that my phone will only perform normally when I charge it with my laptop USB port which I think is around 0.5amps. Anything above that, even a 1amp charger would cause the phone to freeze, reboot and turn off and not turn back on. The phone has been in repair 4 times and the problem is still there. Now every night I'm forced to charge my phone with my laptop which takes an age instead of the fast charger that came out of the box.
Currently my phone is still freezing and rebooting when I'm out and about and the only way I can get it to perform normally is when I plug it into my laptop. This normal functioning would only last whilst the phone is plugged in.

[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 Randomly Turned Off Won't Turn On Anymore

Hi everyone, after trying everything I could to fix this phone I don't know what to do anymore so I'm here asking for other options.
So the story is, I was just using my phone as I usually would that day and it just randomly turned off and won't turn back on anymore.
(it randomly turned off before a couple of times but it would always turn back on)
- It won't go into recovery mode or any other of the 'modes' (I tried all the different combinations of pressing the keys).
- It's not a battery issue as I've tried my battery on my brother's phone (he has a Note 4 too) and it worked fine and I tried his battery on mine and it wouldn't work.
- I tried the 'drain' method (removing the battery and holding the power button for a minute or more).
- I tried using multiple cables to charge my phone nothing worked.
I didn't drop my phone, wet it, root it or anything and it was working fine the day it happened until it just powered off by itself. When I plug it in my laptop it would make
a sound indicating I've plugged something in but nothing happens. It was version 5.1.1 model SM-N910F.
TLDR; Is there a way to somehow recover the files in the internal phone memory?

This is happening to me as well, also started in February. I'm suspecting a hardware issue. Tried it ALL but rooting. In the past 30 minutes my phone has booted and rebooted itself till it died. If someone can confirm it is a hardware issue. Maybe it's time to unite and get it fixed for free. ~Tamarnouche

Recovering data from a brain dead phone may not be possible, as it probably need some internal component replacement which may erase the data(Mostly). Have u tried connecting it to pc? Better give it to service immediately. Good Luck.

My phone has done exactly the same thing, happened in February too, initially it did the random freeze then started to reboot itself, went back to stock software and full wipe but no improvement; now it will only boot if I leave the battery out for a prolonged period, otherwise it doesn't respond to the power button at all.
I occasionally see MMC Read Fail on boot but not all the time so presumably the internal memory has a bad contact or is failing.
Can it be replaced?

I have the same problem with my Note 3. Only if I keep the battery out for a long (over 24 hours) time I can see the boot logo. So if you find a solution to this kindly don't forget to tag me, will really appreciate it.

I was wondering..
I came across this Forum group since I was looking for boot problems with my SM-N910T3
I hope flashing pit will resolve this..
I recently started to have some low level issue and was hoping it was partition/boot related and not hardware.
Randomly phone boot directly into Download mode with error;
ddi: mmc_read failed
Often I have to pull battery and hold down /power / home for 10 sec to boot up again.
Thanks

A5 2016 crashing and restarting all the time, completely unusable. what could it be?

hi guys. my girlfriend has this A5 2016, and it is a complete piece of ****. it restarts on it's on, be it updating, under heavy usage or just in standby mode. it restarts several times in a row, sometimes going into that "optimizing applications" green screen before completing boot. sometimes it stays in this green screen for hours before i give up and reset it. sometimes it works, sometimes it goes back to the green screen. my girlfriend lost appointments a couple of times before learning that she can't rely on this POS phone.
as you can see, there isn't a clear pattern. is there a log in the system where I could check for the cause of all these crashes?

If your girlfriend didn't make any modification to it, prehaps her phone is fake

Maybe something was installed that doesn't work and makes the phone crash in the background or maybe the phone was shutdown while doing an update from the firmware. (it's a maybe, i am just guessing)
If you have a micro sd card (memorycard) in the phone you can remove it and see if the problem is still there. If problem is solved you need to format that card or maybe even replace it with a new microsd card
Also you can reset it to factory settings to remove everything you changed in the phone (after factory reset don't restore your apps in google play without very good looking if the apps are working ok)
If that doesn't solve the problem you can install TWRP recovery and do a full wipe & after that flash the stock firmware with Odin. If that still doesn't solve the problem you need to bring it back to the store where you bought it
