Hello everybody,
- On monday i ran into a strange problem with my N910F. At first it was just not charging whatsoever.
- after the phone ran out of power, i attempted to charge it which gave me a brick with a black screen, vibrating short every two seconds
- Fine by me i thought, went and got a replacement battery (after checking simple stuff like the physical state of the battery (normal) and killing the batterystats (which i heard both yay and nay about so i decided to give it a try).
- Replacement battery charged overnight on the USB Port of my computer (2.0, for the completionists) went smooth (didn't turn it on, just had this bubble animation of charging).
- Turned it on this morning (booting apparently took 3% off my battery) and all well so far.
- finally in my chair at work i plugged it into my power cable (genuine Samsung FastCharging adapter that came with the phone itself) and nothing happened
- tried another adapter (some cheapo 1A adapter) which started charging around 10secs after connecting but decided to stop charging after a couple of minutes
- some shaking and gentle knocking brought back the charging symbol for some seconds, seemed like some loose contact or a broken cable so i felt fancy and plugged the very same cable (the one originally shipped with the phone) to my laptop. started charging instantly and no shaking or knocking stopped this (so no loose contact or broken cable at all)
This is the story until now, put together as complete and organized as possible. For now i'm stuck to charge my phone on the laptop or computer which seems to work. In this progress above i tested around 7 chargers, 3 laptops, 2 computers, 10 cables and 3 screens with both batteries, although the workaround i have now is only tested with the genuine cable as i was just done with testing for the night.
Now for my questions (apart from a touch with the magical fix-everything tool):
- What i see as possible causes based on my very shallow knowledge are either the microUSB port on the phone or the power distribution unit. Anyone has an idea what to check?
- As i have no idea how deep the OS goes, could it be a software issue by any chance?
Even though the device is only ~9 months old, I don't like the idea of going through Samsung for this one as i tripped KNOX already.
Hope there's still hope for me
Cheers,
Fachtal
sooooooo, does nobody have an idea lying around somewhere?

You seemed to have tried using the cheap charger which allowed you to charge after shaking it a bit, have you tried purchasing a new genuine charger?

Tripping Knox does not necessarily mean that you've lost warranty.

I tried around 7 adapters (from cheap ones to genuine galaxy S3, Note2, and Note4), around 10 different cables (again, from cheap ones to genuine samsung cables), 3 Laptops (again with all cables), 2 computers (all cables) abd one of those mobile charging battery things.
The only thing that works is either the genuine cable on my computer or the same cables on my screen at work.
@geevh that's news to me. As far as i heard is tripping know equal to losing warranty.

Have you tried to flash stock firmware, in case it's the kernel?
KNOX warranty shouldn't void your warrant in the EU as I have gotten two knox tripped devices repaired from Samsung before.

I just flashed the official ROM using Odin. Had some problems getting the phone connected while in DL mode (didn't work at all while in normal android mode).
This seemed to be a dirty flash (already was on stock Rom, just put CWM on, rooted the phone and replaced the kernel to have SELinux permissive for Viper4Droid) as it didn't go through the setup process and was like before.
Anyway, charging still doesn't work. Is there anything else I can test? I'm nearly at the point where I migrate back to my old SGS3 and have the N910F sent to the carrier (well, in the end it will go to Samsung) to get it fixed.
Thanks about the whole Knox false knowledge.

I would just give the device in for repairs but make sure to flash a full stock rom and factory reset before giving the phone, since you have already tried everything else.
Good luck

Well, flashing stock ROM seems to be slightly less relaxing than I thought. It feels like I have to connect the phone to the pc, put it on the table in a very specific position/way and then hope that it doesn't disconnect halfway through flashing...
This has become quite an adventure so far and I hope I'll get this done so i can get rid of this very expensive paperweight
Thanks for all the help so far, I guess I'll add the explanation from my carrier/Samsung as soon as I (hopefully) get my device back.

PMIC or Charging IC is probably broken on the mainboard, i hear more N4's have this problem.
Best is to send it for warranty or let the components be replaced by a "good" repair shop.
Most service centers don't check knox status so i would go for that, if all fails take it for repairs if the costs are not too high.
Hi guys, back for a rather unexpected "solution"
When i finally freed up some time to actually get to the carrier shop to get my phone fixed, I was in for a rather embarrasing experience.
The lady in the shop pulled a charging cable and an adapter out of a box, plugged my phone in and it suddenly charged as if nothing ever happened. Now, some time later, it still works perfectly fine, as if there never were problems...
I have absolutely no idea on what happened. Before going to the shop i obviously flashed the stock rom yet again (with the usual wipe user data/cache/dalvik procedure).
Now, on what i had when the problems started: stock BOC5 ROM, touch CWM, rooted and with a custom kernel for SEAndroid permissive (emotion something i believe the kernel was called). Now during my rather extensive troubleshooting I actually flashed the stock ROM at least once and the issue persisted, which is why i just stood there, staring on my charging phone, my jaw somewhere on its way to the ground, unable to form any proper words :silly:
So basically, does someone have a possible explanation to clear this up? If not, I'll consider this thread solved i guess^^
In the meantime, I downgraded to Stock 4.4.4 with CWM, root and xposed (which i really missed on Lolli) and I'd say I'm happy with this :victory:

It's sound strange but a couple of years ago i read somewhere,forgotten where and about the specific device. The thing was that phone wasn't charging eather ,and now it comes.....the solution was turnig around the charger in te power socket.

this indeed sounds strange. And honestly, i didn't pay attention on the orientation of the power adapter (although my stock samsung one is always in the same orientation because the cable goes out on the side (which means it worked in the same direction as it didn't before).
The only even remotely considerable approach would be that the custom kernel along with this synapse app somehow screwed with the power intake and i forgot to wipe everything when i first flashed stock over it, meaning that synapse still had its fingers in the system screwing around with that.
But then again, as I seem to be the only one with this problem and this custom kernel had more than just a few users I don't think this is the way it went (I don't even use an unusual collection of root Apps which could cause some sort of malfunctioning combination of effects).
I had a few evenings just thinking about this and draw some simple mindmaps/schematics to make some sort of a sense...

Only had mine 3 weeks and its broken already. I have been using a desktop charger and have not been forcing it in at all, not once, I have always been very gentle inserting it it, anyway it no longer charges, it looks like the connectors have pushed themselves back so they are not flush anymore and thus no longer connecting to charge or sync.
Not happy about this at all, I had my desktop charger for my HD2 for 18 months with no problems at all, this suggest a very weak connector.
!!! BE CAREFUL !!!
Going to call in at Phones4you and see if they will swap it, I don't hold out much hope though.
Wow bad luck man, but really you don't need the F word to express your frustration.

was it an official desktop charger or 3rd party?
DO a factory reset using code *2767*3855#
(please not this will wipe everything including built in memory, so do backup before you proceed. Backup possible by moving content of internal memory to SD card by copy paste in file manager)
I had a problem when my phone stopped charging after I upgraded firmware, It would also launch Connected to computer screen when it wasnt . Thought its dead.
Did factory reset using this code and its working flawlessly ever since. Seems to be some kind of bug which happens out of nowhere as 2 people I know have experienced this after upgrading to KE2.

I was going to ask exactly the same thing...
I think the OP means that the micro usb receptacle has come away from the board and has been pushed back into the body of the phone. I hope this is not going to turn out to be a common problem as it's something that seemed plague to the Nokia N900 and it took ages for Nokia to acknowledge a design/production fault.
great advice, now it wont boot at all, just goes round in circles....
F**cked.....
anyone got any ideas?
Hi, the charger isnt really the issue, i haven't had any problems inserting the phone into the charger, ie no resistance which suggests to me it was week or loose and has gradually pushed it self back over the last 2 weeks since I have had the charger. If thats the case it would have done this with any charger or cable.
Just spoke to phones4you, they are going to exchange it for me, they didnt even grumble after I told them what happened which I thought was odd, heading off now to pick it up.
Will be interesting to see if your wifi is any better on the new phone stoolzo. Maybe you could let us know. Thanks.
good old phones4you
got it already, yes I really have. Phones4you are just round the corner in PC world. Will check my wifi tonight and report back on the other thread.

remove and reinsert battery
i had this issue when running custom kernels. somehow doesnt happen with stock.
issue happens like this:
u go to bed while charging
u wake up and the phoneis off or very hot with battery and temperature warning
u reboot and it doesnt reboot, doesn't boot, just goes in circle battery display/reboot cause it doesnt seem to charge neither have enough power to boot.
removing battery + cable then putting both back = it boots again and charge normally

Yeah, did all the usual things, I have bricked phones before and always managed to turn them around but we have no CMR to flash anything from ROOT/SD so when it wouldn't boot after a factory reset I knew I was in trouble
The MHL port being loose was the tell tale sign of a fault as I hadn't misused it at all. When I compared it to my new phone I got today it was defo a little further back, just enough to prevent it connecting.
Good old phones4you, fault report to phone exchange in under an hour, impressive.
Just in case the charger had anything to do with this I am going to get rid, dont think it did but I don't want to risk it.
its this one:

Ok so maybe I spoke too soon. Yesterday I was telling my brother that the Note is the most reliable phone I've ever owned.....then....
I started having issues with charging. My Note would not charge, then it would change after several resets. It would charge, then stop, then start again etc etc....making a lot of beeping noises.
Now, it seems to be charging, but Voice talk keeps loading, and I've turned off the home key activation option. I also get the notification icon saying to disable car mode.
I really hope someone can help, thanks in advance.
kris
Great, now it's not charging, again!
Actually when I get the notification issue from Voice talk, the battery starts charging for a second until the notification disappears and stops charging....
Now factory reset my phone again and charging worked while restarting and restoring but when loaded the voice talk app keeps coming up and going off, so I have a black flashing screen constantly....gonna try restarting/reset without restoring...
Hi leicashot, this shouldn't happen. Which firmware version are you currently running? I recommend installing the latest LB1 stock, unless you have AT&T Note.
Some users have reported similar symptoms when there was dust in the mini usb port. Try cleaning the device, and if all else fails, you should send it back to Samsung for repair.

I'm using the latest 2.6.35.7. Any idea how to try clean the port? Definitely seems like something is wrong with the port....
No charging issues for me but my Note started doing the driving mode thing at about 3am today and has been doing it on and off all day!
Exceedingly annoying!
are you trying to charge from a PC or a wall outlet?
I usually charge via mains but it wasn't charging or even plugged in at the time this started happening. It was just sitting on the table by my bed. I even powered it off but it switched itself back on!
Here is how to fix it.
Take out the battery and take a plastic edge like credit card or even a regular tiny small screwdriver and push the pins (strip) inside the phone. I mean, to take the screw driver and push in the pins back inside the phone, in inside the usb charging port. your problem will disappear. make sure your plastic flexible after-market phone cover has a big enough hole at the bottom to allow you to connect a usb cable easily to the phone, or else, cut open a bigger hole on the cover.
Good luck
so here it is again: you have to push in the usb port pins back inside the phone, straight in without bending them. you can also buy a usb charging port from ebay for 22 bucks and change it yourself in 10 minutes. its a hardware problem so stop resetting your phone.
Nop bro i dont think so, cuz it happened same with me sometime after i bought galaxy note same thing happened with me too. I mean exactly same. So before i didnt knew rooting and flashin roms and all so i gave to service centre and they put newer version of ron in it and my problem was fixed after that.

Indeed. I remain convinced this is not hardware and is software related. The main reason for my thoughts there are that as well as the driving mode thing it seems that some piece of software is trying to load up as it asks me if I want to run whatever it is in either Clock or TuneIn Radio. Bizarre. Also, the first time it happened it was bang on 3am. Everytime I turned the phone off it would come back on exactly two minutes later.
The second night it started doing it bang on 1am.
I'm waiting to see what time it starts tonight.
It doesn't (so far) do it at all during the day.
Going to give it a couple of days to see what happens then go figure out how to go back to a factory ROM rather than the the Rocket 22 I have on here now.

I've been having the same problem for a few days now.
I've just pushed the pins in with the corner of my charging cables connector and the problem stopped.
There was also a notification that flashed up saying something like: USB connector or device removed.
Voice talk is still managing to launch itself, even after pushing the pins in. I'm on stock LB2 so maybe I've finally found a reason to flash a GB rom?
Happened to me yesterday. Got a toothbrush and cleaned usb port on phone. Now seems ok

I am running SACs23 4.3V4.2 rom. I have been having now issues. I plugged my phone in to charge for a couple of hours. Came back and the notification light was blinking for sms. I unplugged the phone and pushed the power button. The screen would not turn on. The notification light died out and now nothing. I have tried booting into recovery, hard reset, and pulling the battery. When I plug the phone back in with or without a battery there is no charging indication. The phone is lifeless. Not sure what to do, I have never seen this. When I plug it into the computer, nothing happens. I can not get into recovery or download mode...the phone does nothing. Any suggestions or ideas?:crying:
The micro USB charging port appears to be not working. You can buy it on Ebay for $10 and replace it yourself. Fairly straightforward.

Yes. Charging port works fine. 2hrs later, I put the battery back in and it booted. Used my phone for the next 24hrs and then put it on charger. Woke up this morning and same thing. Very odd!
This happens to me when ever I don't use the original charger
Can you get into your recovery? Sacs, has an update to v4.3 in his op that's working very well if you can download it on PC and transfer to your sd card. Dirty flash it and see what happens. My guess is, you are having the same boot lag issues as most others were having and there is a zip file you can flash in Sac's OP for that also for v4.2.
If you can get into your recovery, dirty flash his update.
Your phone, charger port and wire are fine. It's the lag everyone was getting to get the screen to come up.
Sac's is doing one more update so it may be a few minutes before the link is up, but here is the direct link for you..
http://www.androidfilehost.com/?fid=23212708291682600
Until the update is reuploaded, for the heck of it, dirty flash v4.2 and DO NOT select any of the lockscreen effects like lightening or blue orb. The lag has been narrowed down to possibly being that problem.
Lag issue flash file to be flashed in recovery

Try pulling the battery and leaving out for say ten minutes or so
Some clarification:
1. I 've pulled the battery and waited from 10min to 3hours. No change.
2. Plugging into computer and the phone nor computer responds to eachother.
3. I am using the original Sammy charger.
4. This is the 2nd time this has happened but after 24hrs of being off it still will not respond to anything.
5. I took it to Sprint today and they ordered me a replacement phone. They had 3 of their best techs troubleshooting for 2hrs and couldn't find anything wrong with the phone, except for that it doesn't do anything.:crying:
6. I am hoping my new phone doesn't suffer the same fate. I can honestly say this is my 3rd Sammy phone and the 1st time I've had to take it back for anything and I am always flashing new roms from trusted devs.
This one has me puzzeled! Oh, this happened after I updated to MJA software and firmware but no KNOX! So, maybe I am having an issue with the new MJA....sounds like a lot of phones (various carriers) are. I'll update if I learn anything new.

Sprint just issued an update today that is suppose to fix this issue. If you can get back to stock take the OTA and see if it helps. You have the sleep of death issue and the mk2 OTA mentions sleep issues as the main fix. Hopefully this is what they are fixing.

I hope someone can help explain my S4's odd behavior. I'll try to be brief but give enough details for the experts to get an idea.
- The phone discharges to about 30% and then either turns off or starts to bootloop or just behaves weirdly by closing processes and apps making it unusable
- Once fully charged, it'll finally boot again almost normally but first I have to go into recovery and wipe partition and after various attempts it'll finally boot. Its behavior will be normal and everything will function perfectly well until it goes back down to about 30% charge again
- There are 2 things to rule-out: battery and rom. The battery is brand new and 100% original because I've already changed it thinking that it was the culprit. I'm currently using AOSP 4.4 rom but the behavior is the same with any rom even stock roms
- I can't get it serviced because thanks to the new bootloader my warranty is void
Any suggestions?
USB board/port. Replace it first. Given it's quick/cheap/easy to do on the S2, I think you'll find it's the same on the S4. Search online & here for details/the service manuals which might be useful. You could also pay a local mobile repair shop to do it, but why pay them 3-5x (or more) what the part costs in labour to do it when you can do it yourself ?
Thanks! Will try that and will def do it myself:good:. Am pretty familiar with hardware. I too think at this stage that it's a hardware issue

Just out of curiosity, why do you think it's the usb port? I have to say that it crossed my mind once as well because on a few rare occasions I had problems charging my phone as if the usb cable or port was defective. My PC at times has also had problems recognizing my galaxy when plugged in, but only very rarely so I didn't make much of it
The charging issues you've had, another battery not solving those issues, and the auto shutdowns/auto bootloops for no reason have always been symptomatic of the USB board/port on the fritz on the S2 and the S3 (saw so many of these in S2 Q&A this year particularly), just sounds a lot like it. Put it this way, if it's not, it's something much worse hardware-wise, but I think you'll find the easy fix will resolve it in this case.
So last week my N910F (rooted) ran down to 20% battery and so i put it on charge, thought nothing of it, A couple hours later the phone was dead, extremely hot to touch and just a blank screen with no charging lights, So i unplugged the charger removed the battery and let it cool for about 10 mins, when i put it back together it refused to turn on, tried both recovery and download modes but still nothing tried different chargers and still no lights, nothing. took it back to my local O2 shop to see if i could send it off for repair.
Got home this evening and O2 had kindly returned my phone to my home address, with a letter saying the following -
Thank you for sending us your phone to be fixed.
One of our engineers, has tested your phone and found that unauthorised rework has been carried out on the phone. Unfortunately, this prevents us from repairing it and we are, therefore returning your phone un-repaired.
well after reading this my heart sank and i was guessing i would have to make a insurance claim and hope my insurance would somehow replace it.
I then noticed on inspection of the phone, there was for some reason a new charging cable included with the phone!!!?. I looked a bit further and noticed they had taken the phone apart and it seems they have replaced the charging port, the battery also looks brand new and there isnt a scratch on it (I had previously marked it) So it seems they have indeed carried out some work, So i plugged it into the charger and guess what, it now works fine!!!!!!!!
So thank you very much O2 repair centre!! Im guessing they had to fix it first before they could test if it was rooted or not!!! their letter was a bit confusing though!! :laugh: :laugh:
Congratulations
Sent from my SM-N910F
Does anybody find it weird that o2 would fix mjw2k11's Note 4 only to send it back to him saying that they couldn't fix it because he had messed around with the firmware? Anyway I'm glad that you managed to get your Note 4 fixed.
i dont find it weird. It wont turn on right. but 'O2' wont repair if anyone modify's their phone. So they want to turn it on to see if it has been modified & unofficial but they cant even do that yet. The logical thing for them is to try to get it to boot up, which they did by changing a battery or fixing inside. (which solved the OP's problem). O2 then see's that Knox counters been tripped & they dont do anything further & send it back to the owner. Happy & lucky he is
