Touchscreen quirky when on AC power

Both mine AND my girlfriends gs2 have this problem. When the phone is charging, the touchscreen is not reading the correct point of where I touch. Anyone else having this problem?

Yeah we all are. There is something wrong with the square adapter that came with the phone. Try plugging it into a PC to charge or using a different adapter. It works fine.

I noticed this as well, but only with non-OEM adapters.

And I thought it was only me. Get the same problem only with cheap chargers.
OEM, MT4G, Transformer, Touchpad, Galaxy Player, Ipad & iPhone chargers all do not experience the problem.

I get this problem even when plugged into the oem adapter...!

Do you guys all have cases on?

I don't and I also have this problem.
I believe its the square Samsung charging adapter.
Powered by the SGSII....

Ditto here, it behaves Ok when charged from my laptop, PC and Motorola charger (came with my Milestone), but definitely quirky when charged from the square little adapter that came with the SGS-T989D.

Add me to this list as well.

Same here, but it does change when I use another Samsung adapter like the one from my Vibrant it'll actually work once i use that one.

I have the problem with non-oem...oem is just fine for me

This is happening to me. I am using a Quikcharger for Samsung which I bought from Sears. Anyway to fix this? Because the OEM square charger + data cable is to short to use in bed.

it only happens with defective charging cables
how i know?... i just accidentally crippled a pin of my existing charger, and now even though it still charges, it causes all kind of random weird things in my phone.
so i simply stopped using it, and changed to another charging cable

So you are saying the OEM wire is defective? Has anyone used the cube with a different wire or vice versa?

I just bought this new charger from Sears and it still gives me a quirky screen

This is a known issue with the SGS2. Any inconsistencies or issues with the power supply via AC will cause the screen to tweak out. Possible causes are a bad cable, bad power source (outlet), or improperly inserted microUSB connector. If you try a number of times and cannot get the cable to connect properly, return it or get a new one.

Nexus won't charge while the it's powered on

I have a VZW Galaxy Nexus and it won't charge while it's on,but when I turn it off it charges. Also It will charge while powered on when its connected to my VZW branded car charger. Anyone know why this is?

In settings>battery does it show charging(USB) or charging(AC)?

No I just get a list of what's using my battery life

Are you using the stock USB cable and charger?
Not all USB cables or chargers are made the same.
I bought one micro usb cable that looked high quality but didn't charge at all when in use and charged very slowly when not in use.

Wrong place, you need to check in: Settings > About Phone > Status
Might it be a faulty USB cable? Have you tried with a different cable/charger?

Yeah I've tried two different cables. Haven't tried the stock one since I don't have it.

Although not all cables can carry data, I thought any cable should be able to charge?

Try on a different computer, maybe your computers USB ports are malfunctioning or the GNex overloads them when the phone is on?

Not sure what the problem is. I've tried two dfferent computers usb ports several different outlets and two different cables. The only time it truly charges is when I have it hooked up to my car charger

I'm having a similar problem with the GSM version. I had the original Galaxy S and had to replace it because over time it completely stopped charging no matter what cable I used. Is this an issue with Samsung phones? Now My Galaxy Nexus seems to only charge with certain cables and some cables that it originally worked with no longer charge it. I've tested the cables with other devices and they seem to work. I'm wondering if I should begin the lengthy process of shipping it off to the UK for warranty service. Anyone have a link to a tutorial on how to flash everything back to stock and relock the bootloader?

Resolution?
So today my Galaxy Nexus (GSM) has started doing the same as the OP. I did not charge at all last night on the charger. I turned it off. Took it downstairs to another charger and plugged it in and noticed that it was charging. I figured it just needed a reboot. I turned it back on and left if on the second charger and it quit charging. Now I've moved to a third charger and the same thing is happening....no charge except while turned off.
I don't think I have done anything to harm the phone--the only thing I've ever done to it is swap the battery to the larger version. I'll try to switch the battery back to the OEM when I get home from work to see if that makes a difference. In the mean time, does anyone have any ideas on this? The phone is only ~6 months old, would I be wrong to say that the warranty would take care of this? Thanks.

My SGS2 did this as well. I had to tweak the USB connector on my phone. I bent it slightly toward the screen and all was well, never had to mess with it again.

This is true, the outer pins on a USB are for charging, positive and negative. The inner two are data in, data out. At the very least, a cable will always have positive and negative, so all cables will charge unless there's a break in either positive or negative or both. If there's a break in data in or out, it should still charge but it won't communicate with a PC or something like that.
The issue OP is talking about sounds rom or kernel related. Nandroid > Try something else. Hope for the best.

I've noticed that on 4.1 my USB charging worked fine. Now that I am on 4.1.1 it still charges over USB, but at a decreased rate. In other words, before 4.1.1 it easily charged over night and now it will only charge to about 80%. Does anyone have any ideas why that might be?

I just did the same thing, and it worked. Gnex was only charging when it was off, now, it's fine. I had to do the same thing to my old Fascinate for the same issue.

have you solved the problem?
Are you on stock or custom rom?

Having the exact same problem, won't charge with the original adapter as well as spare adapters, also wont charge through USB. Car charger is the only thing charging it right now.

Explain further?
Could you explain further what you mean by "bent slightly toward the screen?" are you talking on the phone or on the cord? If on the cord, then the whole metal connector? Or just something inside.

[Q] GNex charge cable failure

Hey guys, I have a question regarding your Samsun GNex charging cable. I woke up this morning after plugging my phone in last night to find that it was at 20% battery and the cable was not being recognized. After I jiggle the charger, the phone occasionally and fleetingly recognizes the cable but quickly loses the contact. When I tried to charge the phone with a different cable (my Kindle Fire charger), it worked without any issue.
Has anyone experienced similar failures of their cable in this manner? It worked the night before without any issue but now it is giving me problems. The cable is not visibly damaged, and I am careful with my devices/accessories so I do not believe that the problem is from my carelessness.
Finally, I got this phone from the Verizon store, would I take the cable to them or to Samsung to get it replaced? I hesitate to go to VZW because I don't want them to see that my phone is rooted (in case they ask to plug it in in front of them).
Thanks!

Yes I have the same problem I don't know if its just that they (Samsung) shipped out the wrong charger cables or what but I Use my Brothers cord for his Droid 3 and it works flawlessly snug and all..

Yeah, it worked fine until today, so I don't know if it was because they sent the wrong cord. Oh well, I will get in touch with Samsung about it.

*******Update******************************
My original cable has not suddenly started working again. it now charges and transfers files which is good because my Chinese knockoff cable had a loose fit on my phone.

Same problem here. I bought my phone around Dec 21st and just 2 weeks ago the original cable refuses to charge the phone. It also didn't allow me to transfer files to my phone. I currently have 2 new cables. One cable is from www.monoprice.com and one is from www.cellphoneshop.net (China). Both of the "backup" cables work fine as well as one of them being 8 feet long. (makes it that much easier to plug in at the library sometimes.)
FYI - my original Droid Eris cable crapped out after about 4 months so it does not surprise me. What I would like is a good backup wallwart to use at my office. The phone charges so much faster with the ac adapter.

Solid USB cables are cheap (also recommend monoprice.com) so its not a huge deal, but wish they'd last longer.
Mine's still going strong at this point.

I'm still using my Blackberry cable.

I love monoprice, why spend 150 on HDMI when you can get it for 5. I got in touch with Samsung and after some discussion they had me send my old one in (they paid for shipping) and they will send a new one. I was a bit annoyed that I had to send the old one since it was a hassle, but oh well.

Charging problem

Galaxy Nexus problem - charging problems- it will not charge when the phone is switched on, if I turn it off it will charge partially. Sometimes after turning on it will still have the charging symbol displayed even though not plugged in. Anyone have any ideas? I'm using the original charging cable from wall and pc and I've tried an old cable. Flashed no ROMs on it.

I wouldn't even mess around with it. I would head to verizon and talk with them. Not worth trying to find a fix

No such thing as verizon in the UK but yeah I get you - T-Mobile is my carrier

Yeah, definitely order a refurb from your carrier.

Factory reset first just to see?

You can try it, but it sounds like a serious connection problem. Try a different cable, outlet, plug, and battery.
Emphasis on different battery, it REALLY sounds like that may be the culprit.

Tried all apart from the battery as I don't have another

You have this and it's fatal unless you want to change your own USB board.

Try a battery. Go to your providers store and tell them the problem, they can probably test it out for you.

Simple. The problem is with the micro USB port on the phone. Just wedge a tweezer inside and bend up the nub a bit. It worked for my phone and the problem never came back.

[Q] Is there a fix for the usb port charging issue ?

First thing, sorry if this has been answered before. The thread search never works from my phones. It just disappears as soon as my keyboard appears.
Is there a way to fix the USB /charging port to keep it from being so touchy? I've tried new factory data /charge cable. I've tried expensive brand name cables. They all seem to work for a more th or two pretty well and then its back to charge/not charge sometimes without even touching the phone.
This has been the way with every Samsung phone I've owned and it is so aggravating because, as I'm trying to type or while playing a game it interrupts and causes lags and also the battery will die while I think its charging if I can't see a battery icon.
Other than sending both my phones in for new USB jacks/ports, is there something I can do? I'm pretty capable at fixing electronics if not too technical.

seem to be having bad luck with your ports i would suggest a new charger but im sure you've done that a plentiful of times or you just have really bad luck with phones thats stuff get an iphone JK!!! lol you stick to samsung chargers not no after market stuff right ? and does the cable feel securely tighten or loose when you plug it ? is this phone old new you could have a dirty port spray some air can in that port to clear debris

Hey, thanks for your reply.
I think this problem stems from me being on the phones a lot and I have the the charging /data cable in a lot to keep the battery up. With that, the constant mmovement of up and down from table /desk top, to ear,or car seat /center console to my pocket as im in and out of my car.
The cable always feels loose in the jack. Im sure the jack is stretched open. The chip that is inside, may be has worn and the edges of the board slightly filed down making a loose connection .
Anyways, Ive already had to start charging the battery directly. I've also got a replacement ordered. That's why I pay for insurance right?
So we can put this thread to bed. Thanks

I have the same problem... I'm on my 3rd Galaxy s2...... Phone can be on charger at 15% let it charge for a few hours and when I go back to check on it, it says 10% battery.. I've bought several chargers and batteries... TMobile just keeps sending me the same phone out.. I just got another one on the 13th... What could be the cause of this... Also the phone shuts off while charging... So many dropped calls.. I give up on this phone... What can I do..

Same problem here. The best luck is (oddly) using a computer (instead of a wall charger) and charging while the phone is off. And, the original Samsung charger block and USB are the least reliable of all I have tried. The microUSB end of the cable is slightly undersized. Note: removing the battery completely (while not connected by cable) for 10sec seems to improve the charging.
It has been a good phone but 3 years might be all it can handle. Xperia Z3 compact, here I come.
