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.

And i used this guide to pull my nexus apart.

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

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.

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.

I think this is the same issue: http://forum.xda-developers.com/nex...a/usb-io-pcb-touchscreen-calibration-t2939991
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.
I thought I'd share my experience with this, as I've seen posts in the past relating to a water damaged phone boot looping and I don't think I've seen a proper solution given.
First thing's first, this advice is in relation to a very specific type of boot looping. Nothing to do with rooting, or software bugs. This is boot looping that has come about as a result of water damage. It may not have been long, maybe a couple of seconds in the toilet or some brief rain exposure. Whatever it is, you know your phone has been exposed to some water and it has begun boot looping. There will be no way to get out of it, as the phone boots for 2/3 seconds max before looping all over again. Even when you go into recovery, same thing, automatically boot loops.
Most people, including the official HTC Service Centre, will tell you the motherboard is fried and needs replacement. Whilst it is possible that may be true, it isn't guaranteed. It's an easy way out for HTC, as they can charge you an extortionate price for a new motherboard and not have to bother going through the work of taking the phone apart to find out what is wrong.
The solution may be much simpler - the Power Flex Cable. This is a very small cable that goes along the top of your phone. WHen water damaged, this cable can become damaged, causing a constant boot loop. The reason being it constantly tells the phone the power button is on, causing a constant on/off cycle. In this instance the motherboard is fine and you can get a replacement Flex Cable for less than £5!
There is an easy way to tell whether the Flex Cable is the likely cause of your looping. When the phone is looping, hold down the down volume button only. Don't touch the power button. If your phone still goes into recovery (then loops again) then it is entirely possible your Flex Cable is damaged, not your motherboard.
Next step, order a Flex Cable (they are easy to find). When it arrives, you will need to open your phone (there are guides on YouTube for this), detach the motherboard and replace the Flex Cable. An advance warning, this isn't easy and you have to be extremely careful. One bad move and your phone is history. The motherboard is delicate. If you look around the internet you will find guides which show how the HTC One X is configured. Note that the Flex Cable is behind the motherboard and quite awkward to get off. I would post a couple of links but as a new member I'm not allowed! PM me and I'm happy to share some helpful links though.
You'll know quickly if this has worked. When connecting your phone it will no longer loop. Let it charge for a little while, then power on and hope for the best. If the Flex Cable was the problem your phone will reboot, and you will be able to use it and get your data off.
Note that water damage can have long lasting effects on a mobile phone. Whilst this may solve the problem for a while, it's entirely possible your phone will fail at some point down the line. Prepare for that and make sure you back up accordingly. The above advice may give you a lifeline in getting data off your phone, though, and being able to use it for a little longer. I know that when I was looking around the net I only found this advice by chance, and I think it was on a non-phone related forum. This advice may exist on the forum somewhere but if so it isn't so easy to find. I hope somebody may come across this topic when trying to fix their water damaged phone and find it is the solution.
Good luck!
Same symptoms, but no water damage
Hey man,
Thanks a ton for your post. I have the same issue, as in it won't stop booting at all. However, mine didn't happen because of water damage, but when I tried to do a factory reset (the phone was only on 5% charge so I'm not sure if that screwed it up). Do you think it could still be solved with a flex cable? I tried holding just the volume button down, and it does go into the bootloader so it seems pretty much exactly like what you have described!
Cheers
My only experience with replacing the flex cable comes from water damage, I'm not sure whether a software fault (as this appears to be) could have any effect on the cable itself!
When you get into the bootloader screen, does it just cycle all the way through to fastboot without allowing you to select any other options before rebooting? If so it would suggest your phone thinks the power button is constantly pushed down, which is suggestive of a power flex cable fault.
These cables are very cheap to buy, so if you aren't able to do anything else with the phone it's definitely worth a shot, even if it doesn't work. Just remember that opening the phone voids your warranty, and be careful if you do attempt it, as the insides of the One X are quite delicate. It would be very easy to break something!

It's very easy to do, the flex cable is a fragile piece. There are quite a few parts inside the HOX which could easily snap, which is why I always urge a lot of caution when opening the phone up!

Old thread I know but thought it was worth adding that with a water damaged phone the issues can result from the fact that tap water contains minerals which can leave a conductive residue when it dries - can change resistances, cause shorts etc. What I've done previously is used isopropyl alcohol (tape head cleaning fluid) with a toothbrush on the motherboard. Brought a phone back to life. This removes the mineral deposits and cleans everything. Had to remove the metal covers from the mobo first though. If a phone is basically dead or not working right after water damage then it's worth a go. As de4life says, just need to be super careful on the HOX with all the delicate ribbon cables.
Indeed, the phone should be thoroughly clensed if possible to wipe out any corrosive liquids left behind from the water (especially if it's dropped in an ocean). The effects of corrosion can be very slow and potentially last for months.
M8 please reply to this all the flex cables that I found are 40$+ can you give me a link for one as you stated that would cost 5 pounds
It worked
It worked! I replaced the power flex cable with a spare one on my HTC One X, previously damaged by being sucked by my one year old son - water damage.! It worked!
Many thanks to you man!

Prepare for that and make sure you back up accordingly. The above advice may give you a lifeline in getting data off your phone, though, and being able to use it for a little longer. I know that when I was looking around the net I only found this advice by chance, and I think it was on a non-phone related forum. This advice may exist on the forum somewhere but if so it isn't so easy to find. I hope somebody may come across this topic when trying to fix their water damaged phone and find it is the solution.
Good luck!

Thank you very much for typing this out! My Google Pixel OG (2016), which was made by HTC, experienced the exact same problem. I have just fixed it by replacing the power flex cable like you suggested.

I was surprised to get a notification for this old thread! I'm glad this worked for you. I had no idea HTC used the same design for the original Pixel.
Hi guys,
I was running MIUI on my Galaxy Nexus and had a crash that caused a boot problem, so I got back to stock and some days after I got this on my screen. In the beginning was just one line, but now there are at least 5 of them.
And when I charge, the screen keeps going on and off for some minutes.
Any help?
Thanks

That looks like a hardware problem at the base of the screen near the USB port... Did you happen to accidentally jerk the USB cord out of the phone recently?

Thanks for the reply Guinness,
I forgot to mention, I recently changed the usb port, could be it? My last one was not charging anymore.
I will reopen and change back to the stock port to check.
Thanks

I changed it back to the original usb port, but the lines continue.
You might have dislodged or damaged the LCD ribbon or connector when you were working on the port... Make sure the ribbon connector is tight. If you still see the lines, gently squeeze the edges near where they start and see if anything changes... Worst case, you might need to replace the LCD.
Hello guys, after screwing up my phone I'm using my tablet a lot more. So i'm experiencing some problems. The screen problems increase when i use the tablet more often, but i don't have this phantom touch problems it's actually the screen stop working. It just stays on lock screen and me unable to unlock it, i restart the tablet and still doesn't work. However the strange part is that when i hit the back of the tablet in something it immediately starts to work??? I know about the N7 touch screen issues, but i thought they were software based? But mine looks like it's hardware problem? Can you explain me and help me? Thanks.
Can somebody answer me??

If it's hardware, it's most likely, though not exclusively, the cable connections. You need to take the back cover off, and reseat them one by one. Takes a little work because there are 3 cables, one with 2 prongs. Reseat all of them if you can since you don't really know which one caused the problem.
Warranty?
Ok i saw some videos that it may be replacing the screen cables just as you said, but i have warranty. What to do? If i take it to warranty center it's most likely it will work there at the moment? It stops in random times.. What to do?
Removing the back without voiding the warranty is very simple but make sure that you will wear some sort of protective gloves and not touch any copper foil at all ( or you end up with finger prints.. ). Simply reattach the touchscreen connector cable only and you´re good to go.

Thanks for the info. Actually i can fix it easly not by hitting, but just by pressing the back cover. I saw where the cables are in a video and can permanently fix it by putting something between the back and the cables to keep thwm in place. And when i press they just go in place. For now i will just press it when needed. If the problem increases i will open and reattach all cables in place. Thanks for answers.
