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...

Try this?

And buy an extra battery so that you have one charged while the other is in the phone.
How about transferring files from computer to phone and vice versa with the usb cable? Does that work?
Hate to say it, but this is hardware fault. I've had the same issue. It is weakness of the USB connector plate. Mine was quickly replaced.
You can try to push carefully the plugged cable and connector down - in direction of the battery cover. It helped me to charge the device a few times in order to flash back stock ROM and claim warranty repair.

Good luck !
Mainly i was asking since I'm in the USA and bought my note used. If it fails (and i know its hardware) what's my nest route for getting it fixed?
I was able to get it to charge by pulling spen out and it showed charging icon. Put pen back in and it charged over night???
Really weird?

Might sound wierd but i had the same issue after downgradibg from ics. I know how this soubds stupid but a combination of downgrading, flashing custom 4.2 kernal, and restoring titanium backup. 2 days i ciuldnt charge my phone with 10+ chargers i have.
After formatting my sd, flashing full wipe and starting fresh everything went back to normal. I couldnt tell you what happen.
I was getting dock mode, vlingo and charging on/off flashing across my screen when plugging in charger.
If its harware and you cant send in for warranty. I would suggest opening the phone and taking off the speaker part. Youll be able to see if the charging port is loose or any dirt etc is around. The charging port is $5 on ebay and i think requires soldering.

This is what you do. take the battery out and then take a plastic edge like credit card type edge or even a plastic screw driver or maybe a real metal small tiny screwdriver and push the USB pin strip inside the usb port inside the phone. Not down or up but push is straight inside without bending anything. meaning: apply enough force but don't try to destroy the usb post inside the phone. This will most likely solve your problem. now take a look at the cover of the phone you have bought. make sure you cut the opening of the usb post on the plastic cover so that it allows the micro usb cable to connect without any hindrance or difficulty. I think my phone cover had a small hole in the flexible after-market cover I had bought. I didn't allow me to fit in the micro usb cable to connect easily. I had to push it in, in a slight angle. maybe this is what loosened the usb port pins inside the phone.
good luck. if all fails, buy the usb port for your phone on ebay. type in samsung galaxy note flex usb port and you will see listings. It should take you 10 mins to change the port inside the phone.
Hi every1. I have got a wierd fault. I cant charge my phone but can charge external battery charger with usb lead only via laptop...... Anybody got any ideas as to fixing this...??? I have 2 batteries and have to swap and charge them every day.
Thanx.
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.

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.
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.
Hello
Since a few days, my phone wouldn't charge, it did not detect anything when connected. I have tried different cables and chargers with no result.
In the notification bar the phone was giving a message that the phone was in reverse charging mode, whilst it was not connected.
When i tried to change it to charge only it immediately changed back to reverse charging.
The only way i could charge was by turning it of or restart the phone with the charge cable connected., but After removing the cable i couldn't use it anymore, and the notification of reverse charging would appear again.
I have tried to clean the port, this would work sometimes, the notification would disappear but this was temporarily (max 1 minute, i've read that for others a longer periode).
I found a solution, i hope its not a temporarily one, but until now it alright:
I removed the USB port, disconnected and cleaned every connector en blow on them, also on the back of the USB port (black piece attached to the bord) there was this sticky glue thing (i think its glue), i cleaned that part, some piece of iron plate was bended somehow, i don't know if this was supposed to be like that but i corrected/bended it back a little. After this it started working properly. Somehow I think this problem is due to moisturized parts.
You can watch how disconnect the USB Board on youtube.
I wanted to share this with all, in the hope it will come in handy for somebody.
Huawei stuck in reverse mode fixed..
I have encountered this problem in my mate 10 pro and I think I repaired it .. You have to clean the charging port using an alcohol and a small piece of iron .. The piece of iron should touch the piece that enters the cable and the top side of the hole together. You have to be careful and I am not responsible for any other problems you face.
Thanks for the help, I am experiencing the same thing on my Mate 10 Pro. I will have to try the alcohol trick when I get home.

Hello, did it work?
