[Q] Galaxy Note gone crazy!

I started having a big issue with my Galaxy Note recently. The problem is that randomly it would think that it's charging, or connected in car dock mode, or connected to a PC, so the screed would light up with the sound of being connected, respective menu popping up, media scanning running and all the crap. Once, it even entered the Safe Mode - a "safe mode" writing appeared in the bottom left corner, and it would stay in all the applications and screens. The phone is quite new, one week only, and first three days it was fine. The MicroUSB jack is undamaged and clean. Now I have troubles charging and connecting the phone to PC - I succeed in doing so only from 6-7th attempt.
No idea whether it is a software or hardware issue, because in download mode it connects to Odin seamlessly, and after connecting it to Odin and rebooting it, for an hour it stays calm and connects and charges properly.
The issue is very annoying and drains battery really fast. Any ideas, gentlemen, what this could be? Or should I take it to the service centre?

Are you using a stock rom? if not you may want to try a full stock unrooted rom and see if the issues continue. If they do then take it back as it shouldn't be doing anything like that.
Did it get any water damage by any chance as electrical devices tend to get possessed when a little water gets in there somehow.

Thanks for the quick answer, martcerv.
I am using the stock KKA rom. I used to have J4, then I flasher Rocket V6 rom, issues started, I flashed to the stock one, issues didn't disappear. And no, no water, no drops, and as I said, it connects nicely to Odin and does connect and charge properly for an hour after that.

I had a very similar problem with my Note. It was like it was possessed by car mode.
My solution was to take out the battery for a few hours. I had tried everything and that seemed to correct the issues.
So maybe take out the battery and leave the phone with the back off in a dry place for a few hours or overnight.

Hm.. Will try that

Didn't help, I just don't know what could be the reason... Now, when I connect it to the PC in debugging mode, it mounts the card and USB storage by itself. And then disconnects. Connects again... Seems that the damn thing got possessed. Will take it to the service centre.

I am having the same problem. There seems to be an issue with the USB port.

Exactly the same problem just started happening today, car mode, clock and weird USB stuff seem to be the main symptoms. Running stock ROM, not rooted, if it doesn't sort itself out by tomorrow will be getting in touch with seller for a replacement.

i have the same problem and it seems like the usb port issue. I will try to send in my note for repair and see if they will fix it. If they refuse, then i will wait for the usb port to be available on the net so I can buy it and install it myself. Its a small independent board with a flexible ribbon cable. can be changed in 10 minutes

Okay so tried sticking the usb end in a bowl of dried rice overnight and it seems to have done the trick so I'm guessing some moisture got in the usb somehow, but really can't think how. Delicate little flowers these notes aren't they

Note slipped out of my pocket and fell in a snowy/slushy parking lot after a big snowfall. For a few days after that it would randomly go into charging mode.
Perhaps the USB ports are prone to malfunctioning and the drop in the snow aggravated the existing problem.
Happening less and less though. Hope it isn't permanently damaged.

Same issue on my new galaxy note
After three days, my note has started to do the same.
It suddenly starts to charge with no wire connected, or activates deactivates the car dock mode by itself.
It can work fine for a couple of hours but then becomes crazy with no reason. I'm almost sure that any water has touched the phone.
After entering "crazy mode", even when it has get calm again the phone doesn't recognize the charger wire. Only taking out the battery lets the phone become "normal".
I'm almost sure is a hardware problem.
To be continued ...

I have the same problem as well after playing in the snow but I fixed mine...
First thing I did was lightly blow-dry the USB side of my note on high-heat for about 5 minutes. I didn't blow-dry the battery or battery area of the phone but that doesn't sound like a bad idea either.
The next thing I did might only serve temporarily as the device needs to dry more: go to settings/applications/development and make sure debugging mode is checked. If its already checked, uncheck it and wait a sec... then check it back on.
I've not seen the thing act up since so I'm crossing my fingers for me and the rest of you. Good luck
P.S. Worse comes to worse, you could always get a new USB port off of EBAY and install it yourself which is what I'll do if I see the charger symbol act up again :-|

Fixed !
I fixed my phone too !!!.
Initially I did the same blow the usb side hopping to put out any particule that could be inside the usb hole.
Whit this the phone started to work normally, but one day later it became grazy again, but then I realized that it was only after using one usb charger that I have at the office.
If I don't use that charger the phone works fine !.
Four days working properly !.

I was on KL7 when my phone started going crazy around the third or fourth day. And the phone wouldn't charge when the power was still on, whether it's connected to the pc or wall charger. Cleaned the port and cable ends with rubbing alcohol and that seemed to solve the issue. Wiped cache partition and dalvik cache a few times too. Oh, and I got so spooked I changed back to my previous stock rom. LOL.
Hope this info will help your phones.

poor USB
Well I have had this problem for 1 month now.What finally fixed it was to clean the USB port with brush and nail varnish remover.Some people use a tooth brush take out battery dip brush in nail varnish remover and clean port and leave to dry for at least 20 minutes.I used a brush from electric razor give out a good clean and not to gentle either needs a good clean to remove oxidization.

I'm not a freak but nail varnish and electric razor
Come on

it seems like a common problem as many people are beginning to have this usb port problem after a couple of month (or less) use of the note. Cleaning the usb port will solve the problem temporarily but the real solution would be to change the usb port circuit board from the inside of the phone. The usb port circuit is not available on ebay yet but some chinese supplier is selling it out of china.

Man, this is a scary post...

[Q] Galaxy note not charging

Hi,
First off, I have a non rooted, stock Galaxy note. It's not modded in any way.
The problem started occurring yesterday, all was just fine before. Since then, it won't charge no matter what USB cable or charger I use.
1) Phone on
- I plug the charger to the phone : nothing. The phone doesn't register being connected to the OEM wall-charger.
- I connect the phone using the OEM USB cable to my computer (tryed 3 different computers) : Nothing.
I also tried another charger and several USB cables : no luck.
2) Phone off
- I plug the charger / I connect my phone to a computer using USB cable : the phone boot up and doesn't charge the battery.
Any thought ?
Thx in advance.

Try using some compressed air to clean out the usb port on the Galaxy Note. I had a similar issue with an iPhone once and there ended up being a piece of lint stuck on 1 of the contacts which made it unable to charge. Could be the case with your phone. Other than that contact Samsung and see what they can do for you.

Thx for the advice.
I'll try that out and call over Samsung.

Try factory reset if that could help..

Update:
I tried a micro USB Host Cable (OTG Cable) and it's working fine : recognized and plugged in USB stick is working fine.
Also, I tried a factory reset after backuping my data. All went fine but sadly the problem is still there : no charging.

More update:
After two days, It started working again as if it never happened.
Still wondering what might have caused it

Might be the dust that settled on the battery pins and the contacts on your phone.. happens some times .. glad its back to work.. poor thing..

Happened to me too! It wouldn't charge until I turned off the phone. It worked after I cleaned the phone and usb cable's metal parts--sorry no correct jargon for this--with rubbing alcohol. Make sure there's no lint left from the cleaning.

Yup, had this. On charge with stock charger in the mains. Battery dropping fast, back (top) getting warm. I turned the screen off, left it for 5 mins. Looked again, it was 2% less!
Reboot fixed it.
There did not seem to be any rogue program using the CPU, but I now have a meter and a better logger to examine this if it occurs again. I assume the system got into a loop somewhere, although the phone was normally responsive.

Happening to my phone as well right now. I was worried that the battery is dying so I got a spare online. But it doesn't make sense that its charging and know that it is on one state and not the other.
I panicked so I replaced Rocket Rom with Cassie's. It's still doing this.
Have you guys checked if there is a weird smell from your battery? I thought that was something to look at but dont all batteries smell like that?

galaxy note is experiencing the same hardware problems as galaxy s2 phones. I am very pissed off at samsung. I bought a new galaxy note in dominican republic and after one month of delicate use the phone developed charging problems. Drive mode would start automatically or the phone would shut off all by itself and a battery removal reset would turn the phone on again. then finally, the phone would stay in charging mode even after the usb charge cable is removed. the phone would discharge quickly and then would not turn on. I finally gave the phone to repair dept at claro phone company. they would not fix it and are just showing me a middle finger. Now I guess, I would have to learn to change the charging port myself. After seeing galaxy s2 videos, I see many ribbon contacts would get corroded and need to be cleaned frequently. Many phones were just less than 2 months old and had so much corrosion on the contacts. this is bad design and I think the high current draw for a dual core phone of that huge screen size is causing all kinds of electrical corrosion on the contacts inside the phone. this sucks majorly as I loved the phone when I had it working fine. Now I think I have bought a problem with my saved cash. I will try to repair my own phone soon as I get it back from the repair dept.

My Galaxy Note is doing a similar thing. Not all the same symptoms, but a few similarities.
The other night, when the charger was plugged in the phone kept changing it's mind whether it was plugged in or not - probably every few seconds I was getting the chime it makes when you plug the phone in. I eventually managed to charge the phone by turning it off, removing the battery, replacing it, plugging the charger in, waiting for it to start charging, then turning it on.
Today my phone was trying to tell me it was charging when it wasn't even plugged in to anything!
As with the above post, my phone has been getting hot occasionally and the drive mode has started by itself a few times.
I've used three chargers and four cables.
I'll be taking it along to where I bought it from later on today.

Battery not charging
G Note Battery is not charging .. same problem as of 1st post.
Changed usb cables, chargers, thru PC, laptop, direct wall, cleaning etc
Every thing fails. one month old set ?

OMG, glad to know I'm not the only one. Bought a Galaxy Note from a brazilian network provider (VIVO) and after 1 week of usage I'm experiencing the same problems as you guys.
My phone will only charge when it is powered off and USB connection does not work anymore (even in download mode). Before the problem onset, I noticed some MTP connection and SD Card rescanning without connecting to the PC.
Did a factory reset and got no results. Downloaded Odin Mobile and flashed stock rom and the problem persists.
Has anyone found a fix or the cause for this?
Thanks!
Missing my old Galaxy S...

Strange! After a full night charge, now I can unplug and plug the battery and continue charging from where I stop without turning it off.
I can now get beeps when connecting to PC. It show MTP-Inicialization in the Note screen but I have no access to to Note partitions in Windoes Explorer.

Update: One more strange thing just happened now.
Went to college and left it charging. When I came back at night, tried to connect the Note to the PC and everything is working ok now.
What?!?! Now I'm confused. How can I send it to warranty now? I think I'll have to wait a couple more days.

issue as well
That is my 3rd galaxy note, first one screen cracked, second dont ask me why it was not modified at all but it was so sluggish and froxze all the time, my 3rd one it is rooted device and i have similar issue...I am thinking is it because i was charging it from my wife's htc one phone? I thought they would have the same pins...anyway it is doomed, i tried so many chargers and problem not solved

ok i can comfirm to everyone that i have fixed the problem by buying contact cleaner spray and sprayed inside the usb and beautiful all back to normal!

Nooo..
Have a charging problem as well :/ It detects the charging cable and shows the battery icon with the circle about to charge. But it just turns off before it starts charging, turns on shows the icon again, turns off, turns on, shows the battery icon and so on. I have tried with two different chargers. For me i looks like the voltage is too low? Maybe the battery needs a jumpstart? I'll just leave it in the charger and see what happens. Suggestions welcome
Edit: It's just two weeks old, damn it. Last night I used it untill the battery was empty. That is why I think the voltage is so low it doesnt accept charge.
Edit2: Fixed! Puh! I was right. Battery needed a higher mah to start the charging. Leaving the post as it is for future reference.

same problem here, however it charges from my laptop... how strange?

usb charging problem

hi
i have a problem with my SGN the device keep telling me its charging even when i disconnect the device from the charger i have tried to flash a new kernel with no luck the problem remain and i have flashed a new rom and made a full wipe and im still getting this error dose any one knows what's causing this problem help me please
thanks in advance

Dirty micro usb connector
You might try this. It fixed mine, which is why I wrote it
It might "look" ok, but get a strong power loop (15x) to really get a good
look at it.
http://forum.xda-developers.com/showpost.php?p=25102882&postcount=18

I had the exact same problem last week. Ics was unusable due to pop up: charging paused. Voltage to high. Even when usb was unplugged.
I fixed the problem by running the battery flat. Charged to 100% ran fully flat again and then charged again. No problems since. I think the problem was caused by flashing cm9 when on charge. Sounds unlikly but its all i can think of.
Hope this helps

this problem has been discussed earlier. please do a research and you will see a solution. the problem is hardware not software. take the battery off and then push the usb pins straight insde the phone. take a tiny screwdriver and push the usb pins in the usb port of the phone straight back inside the phone. problem solved.

Final solution to charging problems
Guys, stop messing around with cleaning and pushing before you do more damage to your Notes.
http://www.ebay.ca/itm/180772505164...X:IT&_trksid=p3984.m1497.l2649#ht_3514wt_1002
arrived today, 7 minutes later replaced and all good and working perfectly. It is really easy to do that (unless of course you have warranty, in that case just have Samsung do that for you - I couldn't because Samsung does not give a flying f**k about customers in Canada who happen to prefer the International version of their own f**ked up product - especially with the COMMON problem like this one)
There is a video tutorial on YouTube about opening the note, for this particular part it takes total of 12 philips screws and prying the case with plastic case opener - I ordered this tool of e-bay as well)

You don't need to be an expert to fix this problem...
You get an airbrush and blow some air on your phone's micro USB port. Do it a couple of times and you should be good to go. Some logical reasons why you get this problem, is that overtime some lints and dusts can gather and accumulate on the insides of your Note's micro usb port.
A simple airbrush is all there is to it.

I my case i tried cleaning with air, with alcohol while it was in the phone and when it was removed from phone and nothimg helped. Replacing the 16 dollars part fixed the problem (hopefully) permanently

Just to chime in with my own experience. I started having this problem a few weeks ago. The phone would keep telling me it was charging, even with it not connected to any charger, or would constantly flash the battery icon in the notification bar from charging to not charging continuously. Even rebooting the phone did not help at all. When the phone was off, the screen would continuously show a grey battery, then a green battery with the indicator dots below it saying it was charging (and it was not even connected to a charger). Since the phone was constantly keeping itself awake from turning itself from a charge state to an uncharge state, it would drain the battery quicker than usual, about 10%/hour when screen was off on ICS.
At first cleaning the ports with a interdental brush and some alcohol and then blowing some compressed air helped for a few weeks and then the problem came back. After that, cleaning the ports did not work. I have also tried pushing the usb strip inside the port in as suggested above and that did not work.
I figured it was a hardware problem as I did a search and I saw that the Galaxy SII and GNexus (which are also 2nd generation Galaxy S phones as the Note is) were also having the same problems as well, and the result in most cases was to replace the charging port. In fact there is a 17+ page thread in the GNexus forum where the charging ports are problematic here on XDA. I guess the charging ports in this generation of phones are not that great as I have never had a problem with the charging ports of both my Epic 4G and Nexus S 4G (which were from the 1st generation of Galaxy S phones).
Since I am in the USA, Samsung USA will not fix my phone since it is an international version, and I don't want to ship it out of the country, wait weeks, pay a lot on shipping costs, and hope they actually do fix it. So I decided to fix it myself.
So long story short, I ordered a new charging port from eBay (~$10 shipped) and a set of Samsung phone maintenance tools (small phillips and torx screwdriver, tweezers, a pry tool and 2 guitar pick looking tools) from eBay (~$3 shipped) and watched a few disassembly videos on Youtube and did it myself. It was actually very easy to do and took me no more than 15 minutes. All fixed now, no more "phantom" charging, no constant annoying phone waking-up-by-itself notification beeps, etc.

My solution
Same problem here too...but thanks to some posts in XDA, I could determine that it was basically a result of dirty USB connection points.
So, I used a tooth brush to gently rub and clean the connection points from the outside ( without dissembling the USB port- not that adventurous u see!).
After a little bit of cleaning and blowing air into the port I switched on the phone and the problem was gone!:good:
Been just a couple of hours since the 'treatment'- will keep you guys posted if it comes back...fingers crossed!!

Good luck!
Hopefully yours continues to work after the cleaning. Mine did the same thing for a couple of weeks after cleaning it and no amount of cleaning or pushing the pins back worked. I finally broke down and bought a new charging port and did it myself (see my post above yours). In fact, since I did that fix, it has been forking flawlessly ever since. I still think it's a common problem in the 2nd generation of Galaxy S devices (GS2, GNote, GNexus) for whatever reason since it hasn't happened to either of my 1st generation Galaxy S phones (Epic 4G and Nexus S 4G). Maybe a bad batch of charging ports for our phones possibly. In fact I'm thinking about buying another charging port as back up if it does happen again just so I don't have to wait a few days for the part to arrive.
If it does happen again and cleaning doesn't work, then I really do suggest changing the ports. It is really easy and their are several videos on YouTube that show you how to open and take apart your phone. You can buy everything you need off eBay for about US $15 (charging port and Samsung tools).

Hi all. There is a standalone way to charge the Note GT n7000 battery? I'd like to try if it works before buying a new usb module but without battery I can't.
Thank you very much.

[Q] Note keeps saying charging when not plugged in

Hi all,
I've noticed today out of nowhere, that my Galaxy Note keeps turning it's screen on due to being connected to a charger, when it hasn't. I've tried turning the phone off since it was seriously draining my battery, but it turns itself on and goes to the battery meter and then restarts again. The charging symbol appears when using the phone on and off, and I was just wondering what I could do to fix this?
I've tried flashing a new ROM incase but the problem is still there :/
Thanks in advance!

Try cleaning the contacts on your usb port.
Also your usb port could be damaged.

I have also a similar issue on my n7000 I replaced the port and its fine now Samsung ports from factory are crap

It also happened to me. I had to open up the Note and clean up the usb port to get rid of the problem.

Phone Charging when Not Plugged In - The Definitive Answer
Samsung Galaxy Note
I've had same problem as reported by many others with phone displaying charge icon when not plugged in. I've tried all the recommended solutions. Here's what I've found:
1. Not related to JellyBean update (it happened just after I updated but turns out to be coincidence)
2. Factory reset or flashing doesn't help (it's a hardware problem)
3. Clean out the USB port (there's all kinds of fluff, dirt, lost keys, foreign coins etc in there!) - don't use soapy water for this...
4. Bend the pins (gently) so that they are located in the centre of the port.
In my case it's the charging cradle I was using that was damaging the port. I'm using a flip-case on my phone which means the phone doesn't fit in the cradle properly and I was having to force it to sit on the connector. The pins had become bent and were shorting out against the edge of the port.

Replacing the port is painless, if you have any mechanical aptitude. Numerous youtube videos show how to change it.
Takes about 15 minutes. Just make sure you get the correct port. If you get the wrong one, you're signal will degrade
considerably

I had the same problem and I have managed to solve the problem by replacing the usb port. I bought the usb port from ebay but you must open up your note first to see which revision of usb port board you have inside the phone. I think it makes a difference so the revision number has to match with the old port.
Cleaning the port and straightening the pins helped for a few months but then the problem came back again. changing the old port for a new one solved the problem. I think their usb ports in galaxy phones are crap.

note 5 - USB not recognised and it never fast charge

Hello I have a note 5 - SM-N920C on stock M 6.0.1
about two months the phone stop fast charging and doesn't get recognised by the pc
the thing I tried :-
* try different USB cables ( 2 came with the phone - 2 new once )
* factory rest ( twice with wpie chashe )
* change the charger
I wanted to test other stock Roms but I can't get it recognised by odin .
and I have 2 note 5 all the cables work fine on the other one .
​

I seem to have same issue here.

I have the Note 5 from tmo(SM-N920T)
Baseband - N920TUVU2DPD1
Stock - 6.0.1
You have the exact same issues i've had. I also had issues where when i would have the phone plugged in ( to the wall adapter ) and rebooted it, it would think its a media device like a computer where it could share files and stuff... Also take like 5 hours to charge from 20%
Here I'll make this fix SUPER EASY..
1. Download Package Disabler PRO - I dont think it has to be the pro version but i bought it a long time ago
2. Search for 'power'
3. Disable 'com.sec.app.TransmitPowerService''
4. Reboot
I would add screenshots but as i dont have 10 posts im unable to post screenshots or links to the app in the playstore.

The wife's phone started this Saturday after updating. Also, hers beeps and has the charging blue wave as if she plugged the cable in. While actually charging, it disconnects and starts charging constantly.

The beep and blue wave is normal. The charging and no charging sounds like a faulty cord that's not making good connection

The beep and blue wave happens when she is not plugged in. Phone just sitting there not being charged or touched. We thought at first it was a bad cable, but we've tried several. Even does it on the wireless pad. Therefore I'm not sure it's the port. I think it's software related.

Have you tried safe mode?
Just a warning safe mode reset my wall paper and logged me out of some apps.

Did try safe mode and a factory reset. Sprint store I brought it to tried several cables and another factory reset with no luck so they ordered her a replacement. They weren't too interested in figuring it out. In fact, 3 other people came in with various issues and were just given the number to make an insurance claim without even looking at the phone.

I disabled that apk abd it detects all my fast chargers as fast ones. Where it didn't. If i re-enable it it stops workin

might be hardware issue, Try Wireless charger and see if it charges fast. if it charges good with wireless charger then you have to change you CHARGING PORT.

Had the same exact issue on a refurbished unit . Old note didn't do it, but had to exchange it due to adhesive glue coming up in upper left corner. I did multiple resets and finally went with the option of fresh install as not to import back my apps. It hasn't replicated our issue in the last few hours. I am hoping that takes care of it.
Did you by chance get a random gear VR screen prompting you to download the app and what not? I did and read others had the same issue and only way to get this to stop is to download it and then create an account, reboot and viola it solved it.
Stuff is crazy, love the phone but have had more issues with it over even El cheapo phones....

I got similar problem... now after 10 days I just can not go with this.
my youtube problem.
https://youtu.be/payi2IuJhdI
My NOTE 5 is thinking that is charging all the time. It drives me crazy.
With the USB cable it charges 1 time out of 20 and on a random day. I had to charge it via wireless. It wakes up all the time and can not use UBS.
Strange part is, that I can use my USB micro stick with my root and custom ROM. But that is it. No ODIN, no tranfer files.......
Did everything except change the USB port (it is on it's way). ( that will be my last resort)
ANY THOUGHTS.
I have a feeling that water damage was somewhere in there. (been driving with my bike on a rainy day and it looks like it got a little wet in my upper front pocket.

mine recognises fast charge very randomly. before it happened rarely but now it never shows fast charging with the original cable. the only thing that helped me was ordering a third party cable and using the original ac plug. let me know if that helps to any of you guys!

Ugh. N920a mine started this in March after having it maybe 3months. I called att and told them to send me a new one the other day. Unit arrived this morning. My opinion is its a bad USB port. This imho is the weakest link in Samsung devices-- this POS antiquated USB crap.
The thing would cycle CHARGING -- DISCONNECT, over and over. Wiggling the cord would affect the condition. Fast charge happened 1 out of 20 attempts.
I'll let you know how long the new unit lasts-- my most recent purchase is a wireless charger because, as stated this ***t is bound to happen again.

Unbelievable. My phone was totally fu**d. Than I sad I will fix it my self, so I bought the USB board and waited to get it. In the mean time I used it as normally, just wireless charging and that's it.
But after two weeks, the phone was getting a little better, not fixed, but due to custom ROM and a few tweaks, it did not turn on itself all the time.
But after I played quite a few games, (hitman) the phone did heat up all the time, and that my friends FIXed my problem. NOW the phone works as before the moister get to it.
I have my NOTE 5 back, yee.
SO when you have moister problem - play games.

Hey guys,
I had this exact problem - no more fast charging, no USB OTG or recognized by computer after
upgrade to Marshmallow. Tried multiple cords, different computers (Mac, and Windows), etc.
I sent it in for repair to Samsung and they 'fixed' it and are in the process of shipping it back
I put 'fix' in quotes because the repair tracking says it was solved, but I haven't received it back yet to
test. It should be coming in tomorrow.

Quick charge and USB issues have been fixed! IF you're still under warranty, I'd highly recommend sending it in.
