when i charge my galaxy through the wall socket it's fine, but when i plug it into my laptop (mac) it feels like it is not grounded ....it feels like there is static current running through it when i use the touchscreen.
not experienced this with any other phone.
I dont get that with the galaxy but u did get it with my old ipod nano, the whole body felt static charge

I get that some time from my workplace with poor electrical ground. Running your finger on the pc case alone can also give that feeling.

seem to have fixed the problem, by draining the battery till it switched off, and then fully charging it again, it feels normal now

It's probably easier to show what's happening with a video:
This happens when charging my phone. But only when placed on a hard surface.
Also when the phone is resting on a surface, it doesn't respond to my touch input.
It acts as if there is an invisible hand touching the screen in random places very rapidly.
I hope this isn't a defective screen, because I'm sure this isn't normal behavior.
My problem is almost exactly the same as this: http://forum.xda-developers.com/showthread.php?t=846941, but the explanation doesn't fit in my case, as it's very hot here (high 30's C), with almost 100% humidity, and the phone isn't the same as mine.
Has anyone had a problem like this with the DHD?
On a side note, does anyone else think of "Dial Home Device" from Stargate when they see DHD, or is it just me?
Mine started doing this a while ago. Also only when charging, and only on a hard surface. Bit annoying, but I can get round is easily. Would be interesting to know what causes it though...

Mine does this when I'm using a cheap ebay charging cable. It's ok when using a genuine HTC cable.

Just tested mine again, and it seems ok. Very weird. Was using the same cable too (HTC one). Maybe it bugs out sometimes when it's next to my PC. Seems ok right now.

Anyone confirm this?
I've just bought 2 cables (cheap, retractable) from ebay for emergency use... :'(
Seen demo/display phone acting like that in best buy although phone wasn't flat but on sort of a stand and always on charge...

It has been discussed and confirmed earlier. It happens with cheap non-genuine chargers.
The solution is to use only the genuine charger.
I should add I do have a cheap charger and data cable from ebay that do work ok, so this problem is not universal across all non-HTC accessories.

Lol!
I only use genuine charger and battery no matter what but I hope the cheap cable would not cause this. It's just a cable anyway...
By the way, can you provide the link for the said discussion for my joy reading?
Thanks!
I had this the other day I was holding the phone and had it plug in the HTC charger. I was browsing the web and could not move up and down it just zoomed in or out like I had two fingers on-screen I restarted the phone but still did it I then unplugged it and it was ok.

Just some extra details here, the charger I was using in the video was a generic usb charger, but using the genuine charger doesn't stop the problem.
The screen is in perfect condition, not a single scratch, phone is less than two months old and I only have a genuine cable.
Also this happens on ANY hard surface, a book, tiles, wood, but soft things like wool or upholstery don't cause any problems.

Sounds like a proximity sensor issue.
I had this exact same problem as shown on the video on both the HD2 I had previously and the DHD. In both cases the culprit was not the cable but a cheap charger.
What the...never seen s.th. like this before...
Faulty phones?

Same **** here ;-(
Happens when using a eBay noname docking station! Phone is not laying on a surface! The last time i charged with this docking station there was no problem.
I will try the htc charger...
Slightly off topic but whilst my DHD is charging, if I run my fingers across the aluminum body it feels like its vibrating. I had this on my Hero too.
I'm almost positive its the current, as unplugging it stops the "vibration".
the erratic behavior of the DHD is caused by improper grounding, as the small current from the ungrounded charger is passed on to the phone's body, mostly by a other then HTC cable, there will be a current on the phone, small, but none the less there, as the digitizer measures the electric resistance against the screen on spots, as a human finger(flesh somewhat differs from nothing or non organic objects touching it) it measures a touch, this small current also can give a false touch, thus creating this erratic behavior.
hope this explains it clearly to you all.
so, if you properly ground the phone somehow, it will stop
Anyone else having any issues with the touch screen becoming less responsive when connected to the charger?
Sent from my GT-P7510 using XDA Premium App
Pretty common with capacitive screens when hooked to mains power. Even more common if you're not using an OEM charger.
Just keep in mind how capacitive touch screens actually work, and why being on AC power might cause this problem.
Im glad I am not the only one with this... I noticed something weird when I went to plug my tab into my power invertor to charge over the weekend. It was pretty much unusable while charging... I bought another invertor and it seems to work just fine... I think the el'cheapo I got years ago from w00t! finally met it's match... Try a different source or adapter, under normal charge mine works great.
I use my Note II as a modem and I'm getting really annoyed with the included USB lead falling out - it feels like looking at it too hard will cause it!
The curve of the bezel stops the lead fully engaging
happens to me too
I think it has been designed this way so that if you trip over it you are less likely to cause the note to fall off of a desk or wherever its sat.
Me too. The usb lead comes out very easily.
I thought at the begining it was broken but its good to know it is not just me...
I have problems connecting it to a philips desk clock and charger I have...

Definitely a thing to be careful of when using odin.. you do NOT want the cable to pop out mid-flash...

I've trimmed a bit of the plastic casing off the cable to make it seat better. The side that faces the same way as the screen.

same here, I bought a charging dock on ebay (£6) so it's firmly connected when synching or copying data.
Don't know whether this is intentional or bad design, looking at the overall build quality though I believe it's the former.
I must have a weird note2. The cable fits snuggly and requires a small amount of force to remove it.
Admittedly I am not using the cable supplied with the note2 (I'm using the one that came with the GS3) so maybe it is the cable.

When I plug in the usb for my Nexus 4, I start to notice my battery started decrease when using simple apps and the phone starts to get hot. I am running on paranoidandroid rom btw
Sent from my Nexus 4 using xda app-developers app
Don't worry that is a common problem among many android devices.It will eventually cool down.Charging also leads to the phone getting warm or even hot,but it will cool down eventually.
Since USB is not an AC source of power,there will be a very slow charging rate.or it will not charge at all.it happens with me too.
Try not to use your phone while charging. Not only do you affect it's battery health it also gets really hot
Nexus 4 has been reported to get hot easily so try not to use it while charging.
Also, try undervolting to see if that helps your problem. Im sure ParanoidAndroid comes with a custom ROM and root
and you will be able to undervolt
Good luck
Also another thing when I charge, using usb or wireless I make sure to take my case off, I am using the seidio case with is rubber and has a hard plastic wrap around and find that the rubber does not allow the phone to breath when it is charging making it extra hot.

I disagree. I use an X-line hard rubber case and always have the case on when charging. My phone "never" gets hot. It always stays at its usual temperature. And I don't live in a place where the weather is too cold.
I have been using my nexus 7 2012 for a year now .. it worked brilliant .. but now this horrible issues has sprung in from nowhere .. the battery wont charge up, or rarely it does,, but very slowly. i am running stock 4.4 unrooted . i have checked my ports for dust, swapped several cables and chargers (also used the original charger and cable). but with no luck. Surprisingly the problem appeared suddenly, one day it charged normally , the next day i left it on charge at 60% and returned to find it on 59%.. help me .. this is driving me crazy
Install the Battery Monitor Widget - should give you an idea of charging/power consumption. I'm assuming you've tried using the stock charger and cable?

Yes i used stock and non stock chargers and cables .. i am using battery widget reborn app to monitor the battery stats.. i also attached the screen shots but for some reason they are not showing up
I think your battery connector is messed up. U might have to open your tablet and disconnect then reconnect the cables.

Search in the forum people have fixed it many times u have top open up your tablet and dc/rc yout battery.
]I too have this same issue....
I have the official dock and never had any charge issues until yesterday....
While it's in the dock, it clearly shows it charging and yet the battery meter appears to be losing charge...
I have tried with the original cable and plug among other cables and yet nothing...
The only way for me to get charged is to turn the unit off and yet it still charges painfully slow...
Anyone with a solution other than opening the thing up and hoping it's the plug?
I am running 4.4.2
Mine's having the same problem. It seems to be a hardware problem.. It's charging very slowly or can't be fully charged.
* I have other devices running 4.4 without charging problems.
Mine started with the 4.4.2 update....
It's very strange... If I turn it off and charge... it charges (again) very slowly.... 3 hours and I went from a 2% charge to 59%...
Doesn't matter if I use the dock or plug it in direct.....
So, to me... I would say a software problem... I just don't want to do a full reset and re-install if I don't have too...
my wife's was all the way dead today after not being used and wouldn't turn on. left it plugged in for 30 min and it powered on with only 2% battery. i t is stock unrooted and everything was all good until 4.4.2 is now charging very slowly. I switched to a non oem usb wire with the asus charger to see if it helps. it is the only stock android in my home (out of 7 devices) and I plan to keep it that way for now.

N7 is very easy to open and close back.
I had the EXACT same issue 2-3 times this year and disconnecting the cable and reconnecting it back fixes it EVERY TIME.
The battery cable is short and the battery is loose so movement pulls the cable out. Not all pins are touching so it results in poor contacts or no contact at all.
Its a design flaw that can also be fixed by sticking a folded paper under the battery.
Voilà!

I'll try that when I get home. My n7 has not been charging for so long its starting to scare me. I tried pushing the cables in but it seems like its pushed as far in as it'll go.

Ok...
I have opened it up and reset the battery cables...
They originally looked pretty secure though... pretty tight....
Here's hoping that unplugging and plugging the battery back is solves the issue...
I be back....

Tried unplugging and replugging but it's still the same. I think it's my charging connector though. It randomly disconnects when I plug it into the PC. Tried with 3 different cables even the stock one. But I'm not sure if it's the port or the battery. It charges up to < 60 slowly but it doesn't go beyond that and starts draining. Thinking of selling it and getting a flo instead

Just a thought, but another possibility is that the ribbon cable to the USB/headphone jack flex assembly has worked loose to the point of intermittent connections. See "step 10" of iFixit's N7 teardown
Or, if the connector itself is mechanically damaged, maybe there is some way to buy just that Asus sub-assembly. Anyone have a source?

Edit - wow, folks are selling them on eBay for US $50. yikes.
I have the same problem, I purchased a nexus 7 charging dock from Amazon and it charges flawlessly. The dock charges using the 4 pins on the side of the tablet. BTW...The charging dock is under 24.00+ Shipping.
