Since this morning my phone says it's charging when in fact it's unplugged. I tried cleaning the charging port, wiping cache, full wiping and reinstalling the rom, everything and don't understand why it'll never get off charging state.
I do check in settings while unplugged it says not charging and when plugged in says charging, but it's stuck saying "on battery for 23 min" and the icon never stops from charging....
Any suggestions? It's really annoying... Never had a single problem with my One S...
SOLUTION: Clean the charger port with a hard pointed object (that's what she said), make sure you clean and dirt or particles from underneath the middle piece in the charger port.
Also, if you notice the middle piece is too close or making contact with the bottom, use the pointed object to CAREFULLY bend it up a little.
Do all this while the phone is off and battery out. Use compressed air if available. if you wet it then completely dry it before putting the battery back in.
did you try wiping the Dalvik cache when you did the regular cache?

Have you tested what happens when you install a different ROM?
something like this happened to me about 2weeks ago.
It would say saying/ disconnected none stop.. if i didnt notice it would of burned my screen.
I just turned the phone off and removed the battery

A LOT of users have reported this problem, yet Samsung claims it is water damage and won't do a warranty repair: http://www.reddit.com/r/GalaxyNexus/comments/tqlii/samsung_refusing_to_honor_warranty_for_infamous/
There is already a thread on this which has some useful info:
http://forum.xda-developers.com/showthread.php?t=1427539It ranges from yep your charging port is f*cked or it just needs a clean and little tweak.
To get mine fixed I gave it blast with compressed air and a little needle to make sure all the lint/gunk was out of the port. I made sure the port was straight (if it looks like it is bent downwards slightly, try and pop it back up softly). Then what fixed it for me is to hit it with a little electrical contact cleaner.
I have a feeling the port was getting shorted by something as each of the pins on the microusb port are very close.
Hope that helps
Interesting - I'll have to keep an eye out for something like this on my phone.
I guess first step is the compressed air blast with a needle cleaning of the port. If that doesn't work then on to Samsung to see if they'll honor a warranty repair (outlook not good on this - apparently they claim water damage). Worst case you can get a replacement OEM charging cable off ebay:
http://www.ebay.com/itm/OEM-Charge-...440?pt=LH_DefaultDomain_0&hash=item33746d1eb8
And fix the faulty part yourself or have someone you trust do it.
[EDIT] here's a link to ifixit for step by step instructions on how to take your phone apart http://www.ifixit.com/Teardown/Samsung-Galaxy-Nexus-Teardown/7182/1#.T7pzI8XdOII
Thanks to all the suggestions, it does the same thing even after wiping, installing other roms or going back to stock. I tried cleaning it with a toothbrush but will try with a toothpick or something stronger. Will give updates once I do.
I would suggest the electrical contact cleaner is going to be a good bet too. If it is water damage, it could just be a bit of water has gotten in there (from a table, rain etc) and then when its dried impurities could be shorting the plug.
I am not sure what stores in the states have it (maybe bestbuy?), but we have an electronic store here called Jaycar which sells it. You could even just slip in and give it a quick spray in the isle.
Turn the phone off before doing it, and make sure it is ECC!
Fixed! It was the charger port. All i did was clean it out with a metal pointed object. I also noticed the middle piece was touching the bottom edge. It could've been making false contact. So i bent it up just a little and voila problem solved.
Hopefully this thread may further serve as future reference. Thanks everyone for your help!

I know I don't have a Galaxy Nexus, but the Nexus S can also suffer from the same problem. I believe it's because of the USB ports that are the same.
Inside the USB port of the phone there is a flat plate which slides into the wall charger/USB cable, I've noticed that when this is "bent" down it will show that it's charging when it isn't, so all you need to do is to find something (I used the tip of the missus'one plastic nail file) to "bend" it up about a millimetre or two and all should be fine.
Worked for me, so I thought I would try to help out here because I know how infuriating it can be.
I had this problem a couple of weeks ago. I also had issues with being unable to connect my phone to a computer. I contacted Samsung, explained my issue and they sent me packaging to send it away. It took me 45 mins to get the computer to recognise my phone to return it to stock, but i managed it. I then wrote a nice little letter explaining the issue, that others also had the issue and that I recommended changing the whole charging board.
I got it back a week later and lo and behold, they'd taken my advice and fitted a new charging board. Now it might just be me, but the inside of the micro USB port looks slightly different. I just can't put my finger on why.
Hi, I had this problem but i sprayed "metal cleaner" on a toothbrush and wiped the contact and now it works fine again :3
This happened to me yesterday. First the phone doesnt charge, it was at 25%, After that i charged it with phone turned off, then turned on and battery whas 50% but still not charging. Turned off again, plugged the charger and it looks like was chargin, when i turned on again it was at 12%, like the charger just discharge it xD. After that the problem began, the battery icon shows like charging when unplugged....
Looks like i managed to clean it with a needle, now the chargin notification is gone, and i can transfer files via USB to my laptop, but still i cant charge with AC :-/
And when i plug the usb cable, the notification icon comes again :-/
OMG Thanks it's alive it's alive
After some time my charge port started giving me issues again. I tried messing around with it but all I did was break it. Eventually I bought a replacement flex cable and ended up installing it myself. Very easy to do. Looked up a video on YouTube and in 10 minutes my phone was charging again.

I had to replace my micro usb charging port
When my phone wouldnt stop charging after being disconnected i ended up solving the issue by going here for the part and tools which is $5 posted.
ebay(dot)com.au/itm/Replacement-Charger-Port-Flex-Cable-Tools-Samsung-i9250-Galaxy-Nexus-GQFC441-/180922260932?pt=AU_MobilePhoneAccessories&hash=item2a1fce9dc4#ht_1368wt_1014[/url]
And i used this guide to pull my nexus apart.
ifixit(dot)com/Guide/Repairing-Samsung-Galaxy-Nexus-Micro-USB-Charge-Port/9641/1[/url]
Just be very careful on step 6 "Some have reported the cable is soldered to the mainboard. This was not the case on this CDMA version. It may be soldered in newer revisions or the GSM model."
I broke my volume down because the guide didnt have a warning !
I hope this might help anyone else who is having problems

Could you link the video you used to help replace the flex cable. I can't seem to find one. Thanks!
So my galaxy nexus keeps waking up by itself. The times it does it varies. I've seen a lot of other people have had the problem but no fix.
Any help? It's driving me insane!
Is it plugged in when it does this?
No.
Do you have an app installed that wakes the phone with the proximity sensor? That happened to me before. lol
Again, no. A lot of people have had the problem but i haven't seen a fix yet.
Well its hard to pinpoint the problem obviously without experiencing it. Thats why I ask questions first. It could very well be the screen itself screwing up. I can't really say. Its hard to determine a hardware or software related problem over the internet. If nothing works, I'd say reset your phone to a brand new state and if it continues, you have a hardware issue.
EDIT: Another possibility, your power button.
I had this issue before. But it disappeared when i moved to 4.2.2 kernel. No idea what was causing it down to this very day. I had just given up completely. I tried everything, full wipe. Back to stock, installing with no apps. Couldn't solve it. Then all of the sudden with 4.2.2 it was gone.

Screen wakes up when not connected through USB
Hello,
I'll use this thread instead of starting a new one since I'm having the same issue.
My GSM Galaxy Nexus is running the stock Android 4.2.1 (JOP40D.I9250XWMA2).
Starting a few days ago, I noticed that the screen wakes itself when it's not connected to a power source through the USB port. Also, the battery icon often shows it's charging even when it's not connected to a power source.
I didn't install any new applications. Could it be some application update?
How can I investigate whether it's a software or hardware issue?
Thanks for any hint.

Sounds like a hardware problem. What you're describing is exactly what I experienced, had my USB port replaced under warranty to get rid of it (I believe it's fairly easy to do yourself as well).
Solution
I used to have the same problem, the solution is to flash another ROm, my phone used to think it's charging when it wasn't, it used to boot up automatically even though i switched it off, the solution which worked for me was to switch my ROM or Re-flash the current one.
I had the same issue when the USB-inlet was greasy, dirty and messed up.
Thanks guys for the tips.
It stopped doing this since last night when I tried backing up data and running the Cyanogenmod Installer for Windows that came out recently.
Now that the Nexus Root Toolkit successfully managed to have the phone recognized by Windows again, I'll give it another try.
I expected this to be a bit involved, but didn't know I'd still be at it two days later :-/
it is your usb port
To the OP and all gnex owners with similar problem, you don't need to install/reinstall roms or anything. it's most likely the pin in your usb port. make sure the port is clean and dry, because if it is wet the pin shorts to the inner side and turns the screen on as if your phone is charging. if it is dry and yet your screen keeps turning on, then most likely the pin has become bent and is touching/shorting to the inner side. Get a thin knife or flat screwdriver, and use the point to VERY GENTLY straighten it back to the middle. Read more on this: http://code.google.com/p/android/issues/detail?id=39625
the solution is in post #161. (see how most later posts confirm the solution.) I had this too, and solved it with a point of small knife. hope this helps.
Agreed with the guy above, one of the possibilities is the charging port problem, some claimed that changing a new port doesn't not help. That made me moved to another phone.

Hello,
I just got my N7 back from repair where they replaced the ME571K SUB_BD./AS board since the USB Port was not working anymore.
Luckily the port works now, but on the other hand the Touchscreen is not responding at all.
I tried restarting already without success. I also cannot reset the tablet since I got TeamWinRecovery Touch (and CWM 10.2) installed.
I can connect the tablet in bootloader and with "fastboot devices" it shows up as 077a744a.
Could anyone help me on how to flash or reset the tablet?
Ps.: This replacement was out of warranty, therefore I paid for it. The service center suggested replacing the mainboard (to make money) as well. Before I sent the tablet in everything was working just fine except mentioned USB Port.

Try flashing the JSS15R factory image.
http://forum.xda-developers.com/showthread.php?p=45671279#post45671279
I just flashed (with wipe) the factory image without success.
There's no response at all. Also when I try to get into recovery mode now the opened Android with the red exclamation mark shows up.
Is there a low level touchscreen calibration or something I could run through fastboot?
Anymore help would be greatly appreciated.
I'm starting to think they just put my motherboard in another tablet with abroken display...
I'd return it, it sounds like total screen failure.

That fallen android is just an image overlaid over the stock recovery menu. It just means you've booted into stock recovery. You can get the recovery menu by press/hold Power, press/release VolUp, release Power.

There are various different touchscreen software you can load via fastboot and there is a calibration file in /system/usr/idc, but it isn't clear any of these would help if your screen doesn't work at all.
You can try changing the touchscreen software, worse case, it stays the same:
http://forum.xda-developers.com/showthread.php?t=2428133
Alternatively, you can open up your tablet and check to see if the flex cable for the touchscreen has become dislodged. There are 2 cables that run across the center battery. The one that is reinforced using tape is the one for the touchscreen.
Just did a reset but it didn't work.
I already tried these different firmwares from your link but it didn't make a difference.
I guess the screen is just broken. Or is it possible that the new Subboard is not working with the motherboard and therefore the screen fails?
I opened the back but it looks fine doesn't it? Is the big cable the on for the touchscreen or the orange one?

Yes, that is the cable. You can carefully removing the tape reinforcing the motherboard side of the orange cable and seeing if there is anything preventing a good connection, possibly use compressed air to clear out the connection area. The other end of the orange cable also connects to the touchscreen underneath the usb module so you would need to remove some screws to check that connection.
That's about all I can suggest. It didn't sound like a software issue because your screen completely doesn't work.
Yes I will look at the side where I have to open screws since that is the part they changed. Mabybe they didn't connect the screen.
I also wrote the support already.
Thanks for your help, I will report back.

Hi there
I have also experienced a very similar problem. The charging port on my 2013 Nexus failed to work, I then ordered a replacement part and changed it. It is very straight forward and simple to do for a novice like me.
on replacing the pcb the charging resumed faultlessly but the touchscreen has become unresponsive, i then replaced the old pcb and the screen has resumed functionality, but charging is not working.
The part was replaced by the supplier and it has occurred again, charges fine but the screen is unresponsive. Again i reinstall the old part and hey presto screen is ok.
I am now going to try and replace the actual usb pin itself from the original failed board and see if i can repair myself.
I had also done all the resets and reboots mentioned online.
Not sure if this helps but thought i'd share as its relevant
Many thanks
Is this the n7 2013? If it is how the hell did you get the back off? I tried and was afraid of breaking something.
Sent from my Nexus 7 using xda app-developers app
It's really easy. No tools required. Run your fingernail around the perimeter of the tablet edge between the screen edge and angled plastic. You'll hear the clips releasing as you go. Then carefully work the back off. No glue, just clips. Takes about 1 minute.

Any update on how you solved this ?
I would appreciate if anyone could share the solution for unresponsive touch screen, if it's possible at all. The screen only reacts on the edges, and only to the swipe gestures, not to tapping. But all and all is the same - broken USB, replacement part, unresponsive screen.

Is there nothing to "calibrate" the screen? Asus is supposed to do it for you.
I think the problem is the rev. number of the usb board.
I found this explicative video on youtube, but I can't put the link. Look for "Nexus 7 2013 2nd gen charge port replacement issue"
I have the opposite problem: I changed lcd and digitizer two times, both times touch screen was completely unresponsive. I wonder if there's a software solution for this. I know usb board have different revisions, but what about digitizers? Are all the same for every nexus 2013 model? In this case I have to think touch screen connectors on usb board are broken somehow...

My kid broke the original screen and I replaced it with a cheaper one that worked great until he broke it again
Got a new screen but the touch doesn't work and I can't enter twrp except if I disconnect one of the daughther board connector ribbons (can't remember which one now).
My guess is that the screen is for a different revision board.
Any way to solve the problem?
This is the perfect thread. I have a collection of Frankenstein parts and the problem I've had with 5 or 5 devices (flo) is the sub board. Some work, some don't. I'll try the firmware links and report back.
Has any one found solution for this problem, even my Nexus 7 2013 touch screen has stopped working after I repaired the micro USB port. Actually my tablet was not charging and I figured out that there was some lose contact in the micro USB solder joints, untill then my touch working. I haven't changed any daughter USB board but just resoldered the micro USB port after which my charging has started working and I can even connect a mouse or pendrive through USB OTG cable but the touch screen has stopped working.
So recently ive had issues not being able to flash and recovery from abrick and well i orderded a new part for the charger port that problems fixed and i replaced it. i fixed it but now i have this screen problem? i just spent 20$ for just this usb like wtf do i have to do now? i already flashed back to 4.2.2 to see if it would fix the screen issue but nope same thing. I flashed to 4.4.2 and still same thing i even flashed the white lines fix and nothing worked. do i have to just adjust my lcd little orange ribbon or move it or clean it ? it doesnt seem to be messed up this is a brand new screen.....how do i fix this?
I want to say your connector which is with the USB needs adjusted or such. I believe I read that the display and USB are connected. Like you said the orange ribbon
im thinking that too i recently just cleaned it with alchohal 70% and dried it for 10 minutes under a cooled hair dryer and then i reconnected them and its just almost the same now its a yellow lines kinda sorta....but when i turn it on its white next tho the LG logo and its blue on the sides kiinda scary but the connector or usbpart is brand new

I would say double or triple check your soldering or the connection. Something is linking or twisted. Like crossed wires, or something. Bleed over from something.

Hello comunity
I bought one nexus 2013 wifi... (Second hand) and I am planning to mount it in my car...
well ... i just started preparing the software ...rooting, unlock bootloader and so on ...
then accidently I dropped it on the floor :/
After this the screen is black. It is OK - it is not brocken but is not working at all...
The computer recognizes the Nexus (I can see it from Device menagment in my computer).
Then I opened the Nexus..
Reconnected the battery... and trying to hold the power button for 60 sec...
again nothing worked and the screen is still dead.
Is it possible this to be a problem?
https://goo.gl/photos/k4EYBvWvQynab3v16
seem it is not OK... (There is a black line on the cable ... may be it is a missing part >)
If i buy one of this cables and change it may be the problem would be fixed??
Tnx and Happy new year

Yes, that part has been stripped. Can't tell if that causes the problem, but I'm almost certain it was not caused by the drop since that part was locked inside the connector, unless it had already fallen out when you opened the thing. Where you ripped it when removing, you might want to look inside the connector to make sure the loose bit doesn't remain in there as it could short. I take it you're not in the US. Otherwise, I could mail you an extra cable I have. Good luck with your repair.
Disconnecting the cable caused your issue for sure, be careful before you tinker with devices.
This cable is OK unless you damaged it during disassembly. The most likely failure is the screen. Have a look at it with a lamp at an angle to check for any cracks.
Did you earlier manage to install TWRP? If so boot to recovery and check with ADB file system access.
Well..
Tnx to all of you.
The tablet is working again.
The problem was this cable.
I ordered a new one.
I really couldnt undartand how just one drop can be the reason for damaging the cable.
