The touch screen is not working properly.
It is as if a ghost was thumbing through the phone. It's like an invisible person is playing with the functions and touch screen. This phantom effect used to occur at varying magnitude off and on. When I restart the phone this phantom effect reduces but most of the time does not completely disappear. The extent and frequency of this phantom effect got progressively worse, from couple of times a week to everyday to almost complete loss of function (current state). Now, the back button does not work no matter what I do. Locking the phone and re-swiping it back on provides minimal relief, but soon after the phone reverts back to its sporadic/random phantom behavior. I never dropped the phone, or caused any kind of damage.
Please help.......
Does this happen only when the phone is plugged in, or also when you have it off the charger? If the former, are you using the stock charger?
I am using a stock charger.... But this occurs while it is on or off the charger.
My milestone does the phantom "jerky" movements only when it's plugged in, it gets worse with another USB wall charger that i bought for something else
Where is the manufacturing location of your milestone, I suspect that this problem may be limited to milestones from a specific region....
I am also facing the same issue, got the touch screen replaced from Motorola Center - still the same. It happens very often while using the stock USB cable, effect is little less when using the stock wall charger.
Am also facing overheating issue with this mobile while making calls and using Internet (GSM/3G/Wifi)
I just want to ask has anyone noticed that sometime while using the ®S-pen on note the screen responds even before the pen touches the screen!!! well it doesn't happens everyone but once in a while particularly when using note while charging, the other thing is the screen does brightens up if u bring the s-pen near the screen before it goes to sleep mode. Is this normal?
One thing more while charging the screen becomes Less responsive, I mean it need a b it hard press for thekeys to response on the screen
are you using it while charing using a computer's usb port? some computers aren't well grounded/earthed - eventually that'll mess up your touchscreen. you should use the official charger or a voltage control usb cable.
thanks for the reply
well i use the wall charger to charge my note.....and even after recently updating tbe firmware. ...the problem still persist.....what i have noted is the hard press problem occurs when 80% of mobile gets charged. The s- pen response is the same even after updating.
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?

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.

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
Please tell me someone else has experienced this.
When using and charging at the same time under Windows 8.1, the touchscreen goes crazy where one touch results in about 5 random touches all over the screen. Only way to stop it is to unplug the charger.
It seems to be something to do with the charging port, if the cable is putting slight pressure on the port in one direction or the other, then it has that effect on the touch calibration... very odd.
