This never used to happen, but I switched to a new charger (my car charger with a wall socket adapter) and now, when the phone is charging, any touch input to the screen gets..well..I suppose the best word is "Garbled". If I try and switch between homescreen pages, it will almost appear as if it is "struggling" to do so, like, it will shake and stutter and maybe get halfway to the new page but will stay on the first. When browsing, about eight of ten touches to anywhere on the screen will immediately send the page to magnifying glass mode.
This only occurs when charging, and only since I started using this new charger adapter. Any ideas?

I had a very similar problem but what i had was an USB AC adapter. I plugged the phone into the USB slot using the USB cable. Everything seems to be charging fine but then it starts to really screw up.
This did not occur when recharge from the laptop. So It was easy to conclude that there was some kind of problem with the charging unit compatibility.
Maybe you should also try a different charger.
I accidentally dropped my Nexus One when I was taking it out of my pocket.
Now, the touch screen or the charging port does not work
The screen turns on fine, and the trackball and power button work fine, but the screen isn't responsive at all.
In addition, the screen says that I have 0% battery left, even though I know I have well over 80% left.
I've tried to plug in a USB charger and it wouldn't recognize it at all. When I put it on the dock, however, it recognizes it, but still, there is no charging indicator.
Is the phone done for?
Thanks
With all those faults, maybe, but there might be hope. The digitizer connection and charging port internals are all based at the bottom of your phone and seeing that the power button still works then the bottom board is probably damaged. Try eBay for the parts. However if something has been physically damaged on the charging port then you'll have to make sure to change it too.
Update:
Phone is back to working state after numerous reboots and battery pulls.
Can anyone tell me why it was behaving this way?
I've been using third party chargers for a few days since my original email charger broke. However whenever I'm using the phone with a third party one the touchscreen is a bit less sensitive and responsive. However, I as soon as I take it out it behaves as normal. I wonder if this happens to anyone else? And also can it cause long lasting damage to the phone?
I too have the same problem.. its not that quite responsive when its charging.. Im using by the way the latest stock LC2.
I think this is inherent irregardless if your using the stock charger or any 3rd party charger for that matter. This issue is not on the chargers actually but on the 'laggyness' on the Note's screen when your using it (while it's charging).

+1 Also observed this when charging from a friend's HTC charger, also read a thread about this a while ago, although there was no definitive answer from what I read, just people reporting the issue...
Sorry mate, no solution from me, but you can be sure you're not the only one experiencing this issue.
I'd imagine it has something to do with the fact that the charger may not be able to supply the power that the larger Note battery needs...
LE: No, charging with its original charger or my S2 charger, or even my Galaxy Ace's charger does not make it less responsive. HTC charger...does
Used to have same problem with iphone too. Cheap Chinese chargers have same effect.

I think from a simple deduction, when your charging, your actually charging the phone's screen itself. Now this maybe wrong but I've read somewhere that what's mainly holding the power on all touchscreen phone is the actual screen itself.
So if your charging the phone, your actually charging the screen and if your using the phone(naturally using the screen itself) you are in effect disturbing the charge because the power it needs to fill up to recharge the phone is being use also to discharge it (thru constantly using the phone itself.)
This is an issue with many android devices. And some do it even with the OEM charger. I've personally experienced it on 3-4 of my phones.

This happened on my HTC EVO even with the factory charger.

I think if I'm not mistaken.. this all happens to all touchscreens out there, irregardless on what brand or make/model your using.

Sorry, but this is bull****. Phones have batteries like any other portable device, and this is what is charged.
I am speculating entirely but it is most likely that the voltage coming in from the USB cable is ****ing with however the screen detects your finger (i.e, via capacitive sensing). More speculating but I assume that having some sort of electric field near a capacitive screen will cause issues in detection (I've had the same effect happen with the capacitive buttons near a plasma ball; they caused false detections of the button being pushed). Then again, the phone is full of electronics + radio transmitter so I might be wrong.
Basically, buy a better cable, or it might just be a general fault with this sort of thing.
My HD2's screen used to go crazy when I charged it with a Chinese charger, like random screen touches at warp speed. If I used a well made charger, all was well.
The touch screen did eventually die on the HD2, and I had to send it back for repair under warranty. Now, if I get any jittering/non-responsive screen behaviour, I ditch the charger.
I've experienced this too, but it is not necessarily the charger, but the amount of power delivered by the charger.
I used to live in a rural area and the power supply was bad. We only got about 150V through the wall socket instead of the full 240V.
Using my stock charger on my Galaxy S, the screen was laggy, but if I used the same charger on a good power outlet in town, it was fine.
I've also used cheap no name chargers that are laggy even on a "good" wall socket.

speculation and assumptions are just cousins..
Anyway, you are talking about capacitive sensing and stuffs. Capacitives and resistives only apply to touchscreens and none on qwerty phones. Your 'speculation' about electric fields on capacitive screens are actually correct, but I would like to go back to what I said again, the phone draws power from the screen itself. So when you touch the screen (to perform gestures on it), you are actually drawing out power from the phone. your finger performs a conductance to the screen. Your say of 'false detection of the button being pushed' are actually magnetic fields that is try extrapolate from your fingers (as a magnet) to the screen, thereby causing a marginal errors on the screen's predefine calibration.
That is why you may have notice that whenever you have your phone charge, and your actually using for example to type a message on your phone, you can clearly see a margin of seconds in delay when letters will be registered to your message.
Try to simulate that with the phone charge and when it's not. Clearly you will see what I mean.
this is what the word- ferromagnetism is all about.
anyway, I won't delved with that as it's in the realm of physics already.

Had this same problem on my Dell Streak5 when using a non stock charger. The fix at that time was to purchase the small longitudinal magnets that are made to surround and clamp onto the usb cable. I had to place two on the end closest to the Streak. Corrected 80-90% of the problem.
I got the magnets at Radio Shack. It's been nearly two years ago, but I think I paid about $6 for a pack of 2.

What? Only 150V? I don't believe it. How then other things work?
Sent from my GT-N7000 using Tapatalk
Well I was told it was 150V.
It took a lot longer to charge my phone or laptop there than it did at work in town (using the same charger in both locations), so there was definitely a lower current coming through.
Solved irresponsive screen when charging
After eight months trying to find a solution, today I have tried with my iphone 4 charger and my Kindle cable and, for the first time,I am able to write properly, as I weren't plugged. I have to say I don't like this device, it's very slow and the screen goes green almost everyday.
NICE GUY
Well this problem is not because of screen quality. Its all about with the wavelength of current supply and change in frequency . Its create some magnetic field and makes your screen behave weird. When we get proper ellectric supply we don't face such problems. Also cheap chargers don't follow quality levels and they generate uneven frequency thats why flux created by them makes screen behave weird.
This happened to my old HTC Incredible S (Vivo).
It only happened when the 5V charger was lower than 1A.
Quite strange.
But you could check if your charger has at least a 1A output.
Should be on there somewhere.
The stock Samsung chargers are 1A as well I believe.

Hi everybody...
I have an issue for you...
Yesterday I was using my phone and battery was aboout 40%.
I then took out it from my pocket to switch on the screed and it didn't switch on...it seems the screen was on but black...
- I tried to press the switch button, but nothing...I connected it to my portable battery and nothing too...
- I tried to switch on by press all three phisical buttons and I had a short vibration and nothing else, just another vibration after about 20sec...
That makes me feel that situation was possible to fix...
Of course the battery couldn't be removed and put on again...
Finally I arrived home and I connect to electricity and nothing, I connected to my PC and I reboot the phone by the utility: it works!!
I was worried and I would like to know what happened and if that's possible to repeat again...
Thanks!

This phone doesn't play nice with a lot of portable battery chargers. Try it with the charger that came with it?
A short while after you plug the charger in, it should appear to boot and display only a charging screen. Once it gets to 10% or 15% you can pull the charge cable out, power it on normally and then plug the charge cable back in.
Oddly, Nokia micro USB chargers seem to work well with this phone, if you have one of those spare.
Hi!
thanks for the answer, but you maybe misunderstood, I know about difference between charging from portable charger and normal...it happened with my backflip when it was completely empty...
Maybe I didn't explain well...the phone went "off" alone, but I was sure battery was about 30%...and it didn't work, just the screen on and black...
In my case even normal charger didn't work to reboot phone...
My solution was just to connect to computer and reboot with the tool...
but I don't know what happened, till now it didn't happen again...
p.s. I have a portable charger bought on groupon, that it works, but it's extremely slow...
bye!!

My screen either does not react on touching at all while charging, or its reactions are delayed by few minutes. Animations are smooth though (etc. cursor blinks at pin screen normally, time changes normally, battery level changes normally), so it's just unresponsive on touch. If i plug charger off, it's working correctly.
Because this is how phone worked when I got it new, I thought that maybe ROM change would help. So now I have omar rom on it and nothing changed in this regard. Does anybody have same problem?
Use a good charger! I'm 100% sure that you are using a cheap power adapter... Cheap charger do not properly filter current and it is the source of issues with capacitive touchscreens...
Thanks, today I got suspicious that charger may well be the source of problem because now charger stopped working at all! It came with phone but it was shipped from hong-kong because I bought it off ebay, so you may be right that it's just cheap replacement of real adapter.
I have this problem when I connect xt890 to computer
