[SOLVED!](Q) Help! Phone showing it's charging when unplugged...

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

Read an weep: http://code.google.com/p/android/issues/detail?id=23789
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!

Phone only charges when it is off.

Starting two days ago, my phone will only take a charge when it is off. When it is on, it acts like nothing is happening when I plug it in, although sometimes it flashes the charging symbol whether the charger is plugged in or not. I have the latest atop build, although I have been running the rom for a couple weeks with no problems. Also, the gps struggles at times. Any ideas?

Same problems here with charging...you are not alone!!

I had this problem too. Was gonna take it back to Sprint so I Odined back stock and it's started charging. So try doing that. It worked for me.

My wife had that issue when we first got her phone. Ended up re flashing the ROM. I still ended up getting it replaced by VZW since it had the issue with dropping signal.

Had this issue with my VZW Gnex. It looks like it is charging when it is off but I'm willing to bet it charges really slowly. There's a defect on GNEX models where the pin on the connector gets bent down.
Try either using the stock charger as it forces the pin up a bit or search on xda for this same issue. I fixed it by using a thin knife blade and gently pushing up the connector. I only had to do it once and it worked well.
Hope that helps!

Hi, I've been having this problem since a couple of days and this post just remembered me that I had run into the same issue in my very old Motorola Milestone. Here's what I did then and what I did now on my GNex, and I think i've found a solution.
You'll need a needle (the thinner the better) and a can of electronic cleaner, if you've ever opened a PC to clean the memories and slots, this is the one you've used alongside the compressed air can. You can find this on your local electronics shop, and it shouldn't be too expensive (think of an equivalent of RadioShack, since in my country there's no RadioShack).
Now, let's get on with it.
Turn off your GNex and pull out the battery.
Now, VERY GENTLY, with the tip of the needle try to pick out all or the majority of the lint deposited in the charging port. You'd be amazed.
To wrap up, apply a bit of the electronic cleaner into the charging port, clean with a cloth the excess on the chassis of the phone (do NOT use the cloth into the charging port, because in doing so you'll risk leaving lint behind) and let the charging port dry for 5 or 10 seconds, it evaporates really quickly.
Now put the battery back in and power on the phone once more. Let it fully boot and plug your charger in (as recommended in this post, you may want to use the one that came with the phone). In my case it worked.
Not sure if it's definitive solution but it does work now. This happened to me about a month ago running AOKP, I thought it was the rom doing some funny bussiness with my phone, so I switched to Paranoid Android, and it happened once more the day before yesterday. I was ready to switch roms today once more but decided to Google around and again, thankfully I came across erodriguez87's post which reminded me of what I did in the past. I'll update this post for this next month to let you know if the issue happened again or not, to encourage people to apply this solution (or not). Cheers.

I used a toothpick to bend it up slightly (towards the screen). I didn't want to use anything metallic in case shorting the connectors might cause damage.

Weird thing!!
As everybody here I am having this very same problem, not charging anywhere (mains or pc), even with stock cable and charger.
However, when I tried the eSATA port it worked fine, and I can access the phone normally
Any idea why?

Solution ?!
I had the charger read normal USB ports and charger.
I have done these steps so far, so I guess they must be the solution, however I do not know if the solution is permanent or as some people pointed out it is a come-and-go problem, anyway here are the steps:
- Restart bootloader ( shutdown your phone and hit all three buttons together - GNEX - and press volume down button once and then power button, then volume up and power to start phone again).
- Enable Developer Options ( You do this by tapping several times on the Build Number in About Phone)
- Enable USB debugging in Developer Options.
Again, I don't know which solved the problem, and if it is a permanent one, anyway try it and let me know the result

My son is having exactly the same problem, his Galaxy Nexus only charges when it is turned off.
I found a solution (sort of)....
I discovered that when I put the charger in the wall socket 3 times quickly after eachother (like: tak tak tak) and leave it in the third time, it sometimes starts to charge.
maybe you have to try it a few times to see it work, it doesn't always work.
It should work within 10 times trying i would say.

Damaged touchscreen - can the rest be salvaged?

Hi everyone.
After a sudden heavy rain, I got some water in my Gnex. I tried the old bag of rice trick, only to find out the USB port was not functioning any more, neither for PC connectivity, nor for charging.
Following the advice of a person I no longer consider my friend, I tried spraying some Isoprpyl Alcohol in the USB port. It did get it to work correctly, but it damaged the digitizer, meaning I get random touches on the lower part of the screen (where the Back, Home and Recent apps buttons are).
I took the phone to a service centre where they tried to clean it, but the issue remains. I'll go there today with my wife's phone to see if it's indeed a touchscreen issue or a motherboard issue. I'm not sure if I want to invest in a new screen (over $100 + maybe a new back cover since the current one has quite a few scratches and cracks) and I'm thinking of maybe upgrading to a Nexus 5 or Xperia Z (the latter being waterproof).
The question now would be, could I do something with the hardware? Like, root it, connect it to my wifi and use it as a web server, or connect it to my TV through an MHL adapter and get a "smart TV". Can I get it to ignore touches on the screen completely, and only accept an OTG/bluetooth mouse input?
Any idea is welcome

One day I got caught in a storm having my Gnex in my pocket. Vacuum and rice tricks didn't work completely, as the phone was working properly besides recognizing the sim card (Mboard issue). What I did was buy a broken screen nexus off of Ebay, and exchanged the screens.
Now I have a fully working mobile phone, plus an MHL connected - XBMC enabled smart TV box, connected with bluetooth mouse/keyboard.
Question: Why would you need to ignore touches on the screen?

As I said, after spraying the USB port with isopropyl alcohol, it appears to have touches all over the bottom part of the screen, as if someone was constantly keeping 3-4 finger and touching away at the soft buttons. Cleaning the phone in a service centre did not help.

Sorry, I missed that info. Try searching for 'touch blocker' in Google Play. Don't know if that would work on a Gnex though.
Another (hardcore) idea would be to disconnect the screen altogether.

Charging Struggles - Connection

Morning,
It appears that the charging connection on my M7 is a bit off. It just started recently about the last week or so where I have maneuver the cord/plug around to get it to charge and even then any slight adjustment will stop the connection. It's resulted in multiple instances where I left my phone to charge and came back to it dead.
Does anyone have any experience with this? I thought it was the cables themselves but after trying several and knowing they work with other phones it appears to be the internal connection on my M7.
I haven't dropped it, gotten it wet, or any of the sort.
Any tips/advice/help are greatly appreciated.
Thanks!

Sometimes the contacts in the phone port get dirty. Take a small needle and lightly scrape off the five little contacts in the port. Has not happened to this phone yet, but with my old incredible it did once or twice. If that dosent work, the port may be faulty.

Ended up bending the whole connector back into place. Seems it go bent towards the top. Connection appears to be more stable, we'll see how it holds up.

2 serious issues i need to fix with A7 2017

Hello, i only have my smart phone (my first one ever) since yesterday.
Managed to set some things up but i can already tell these devices consume a lot of time to do be set up and working right.
One of the first things i did was upgrade it to the latest Android version (7).
Today i took it to the pool to test it's water resistance - it is water resistant, that's the good news, but the bad news is that every time i held the phone under water it would stop recording the video after just a few seconds being submerged, and this with both, front and rear camera - it always showed some note saying something like "in this mode it can not zoom in and zoom out"!! Huh, i did not try to zoom in or out at all and have no clue why it would do this, anyone having an idea??
Next problem ... yesterday (with the original Android version it came with still on) i could connected the USB cord to the laptop and get my pictures out of the device .. today every attempt (except 1) gave me a Windows error message saying something like Windows can not recognize this USB device!! I tried everything, plug te cord into the USB2 port instead of the USB 3 port, same problem, i rebooted te laptop, same problem, i rebooted the phone several times same problem, what on earth is this and how can i fix it??

Hello, are you sure you have the android 7.0? Thanks
You should do factory reset, its highly recommended after android upradge. Be sure to back up everything important, as it will erase internal storage.

7.0 !!!

The phone being water resistant as far as I understand does not mean that it can operate normally under water. It means that being submerged in water (hopefully) will not destroy it. Your particular problem might have to do with the touch screen. Capacitive touch screens can wrongly detect humidity as touch - even if you use them with wet hands. So maybe the display just detects user input while under water?
For the other issue I am afraid I cannot help. Windows can have the most bizarre USB issues. Just make sure that if you ever you did submerge your phone, you do not plug it to the PC (or anything else) before you are absolutely 100% positive that there is no residual humidity in the USB port.

Thanks for the useful reply, i can actually by now answer the issue with Windows not recognizing the USB port of the smart phone, and hopefully this will help others that i have noticed have come across this same issue in great numbers .... I noticed first that also quick charging only did slow charging, using the same port as needed to connect the device to a pc (USB port) than i also noticed that the speakers had no sound .... so i dawned on me ... there is HUMIDITY from the lengthy under water testing in these two "cavities"!! I mean, no water went into the device as such, but some humidity remained in there even though the rest of the phone was completely dried up and everything else was working just fine. Did what i learned online somewhere ... blow it out with the mouth as good as possible and than drop it into a bowl of rice (the rice sucks up moisture like a sponge or even greater). After an hour or so the USB worked just fine again, sound was not yet back in the speaker only in the headset, but after another 'rice hour" also that came back to live!!
Now i only have to find out if under water video taking is simply impossible .. but than again, i saw plenty of such under water videos taken by people in pools, so it should actually be possible, just how??
Yes, touch functions do not react well anymore when the hands are completely wet and this is something don't get, for photos we can use the volume rocker, but for videos not, but it would make a lot of sense to have the option as well for video when the device or the hands are very wet.

I am not an expert, but to me it seems you were lucky the use of the USB connector containing residual water did not damage the phone (or perhaps even the PC). No matter how waterproof the device itself is, due to the open design of our devices' ports, water can collect in them. If you plug a USB cable or headphones, a current will flow. Water in a connection like that can cause a short-circuit. For that reason my old Xperia had little port-doors that sealed the USB port. Unfortunately, those are prone to break off - and simply a pain in the back side to open and close for every charge.
My A5 got wet once, and there even was a message along the lines of "Moisture detected. Please do not plug anything until 100% dry again." And I think that advice should be heeded.

Nope, it still says 6.0.1

I find it absolutely crazy that you tested your device by submerging it in water for an extended length of time.
Water resistant does not mean waterproof.
I highly doubt that Samsung actually intend the phone to be used under water. Moreover it's protection against accidently dropping the device in to water and gives a level of protection where the device won't be instantly ruined.
They don't make specific underwater cameras for nothing.
Secondly the error regarding the malfunction isn't surprising either. The focusing system probably isnt designed to cope with the refraction effect of the water.
It may work in fixed mode, I don't know. However I don't think it's actually intended to be used that way.
Let alone the damaging effect of electrolysis by passing a current through a water soiled port.

Fixed mode??

Thanks for your answer ashyx.
I did not submerge the Samsung Galaxy A7 (2017) without due prior research!
Meaning .... if you check on Youtube for under water videos taken with this particular smart phone you find a bunch that all seemed to have great fun with it for extended periods of time in the pool, so i assumed if it works for them it should also work for me .... but, of course, your point was also of concern to me, none of these videos tell me what happened to their phones afterwards etc.
On mine the headset, for instance, still works for sound, but the volume and mute buttons on the headset are currently no longer reacting and the speaker is off and on still .... on the other hand, the water resistance clearly points out "can be submerged in water for up to 30 minutes and i am not sure if it says a debt of 1.50 or only 0.5 meters, and i never put it further down than maybe 10 or 20 cm's and for less than 5 minutes each time, so, it this IP68 or whatever it is called is of any real life truth and value the device should have zero problems with being under water for a video of 2 minutes at 15 cm or so dept.
Your thought of the water interfering with the focus metering i can agree with, was also my thought, but in all the YouTube videos i did not see this type of problem , so i am not sure if this was a case that these people all new how to set the camera into some FIXED MODE - can you please let me know how to do this, i did not find any settings for this???

Won't the message about moisture warning appear not allowing you to charge?

Absolutely Pandotaz, but this message appears on the login screen and i have no login pwd or the like established, so it disappears quickly .. not to mention the small and hard to read print, in other words, easy to over look, exactly what happened to me, but that's what happens to not-so-smart- smart phone beginners who are already a bit older than average :crying:
At this point i would like to repeat my question in last reply, how do i set a smart phone camera to "FIXED MODE " anyone??
