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.

Hey everyone.
I use the magnetic dock connector to charge the phone at night, this way i hope i'll preserve the water-tight flap that covers the Micro-USB port.
When the magnet attaches to the phone the phone automatically starts to auto-rotate , even when it's disabled in my settings. I know this has probably something to do with people that use desk-stands with a dock connection, while keeping auto-rotate off.
To me, this is very annoying, because when i charge the phone i use a cable. I try reading/watching movies at night while my phone is charging, but the dock-enabled-auto-rotate does the rotation in all four directions.
Is there any way to bypass thing mildly annoying feature?
Thanks a bunch.
Yes very annoying this is. I suspect it's not possible to disks rotation consisting the only official magnetic charger Sony supply is for the dock whereby the device is connected horizontally hence rotation is required. By that logic I'd say no (for now)
Those of you with the Samsung LED wallet case: When you place/remove it from a wireless charger, do you see an LED battery icon showing on the front of the case at all? I noticed that I do get an battery and percentage icon when I physically plug/unplug the phone, but not when using wireless charging.
nope! the case uses NFC and might interfere with the coils used for wireless charging. You'll notice that the LED case needs to turn off for charging to start/work. Say you get a message while it's on the charger you'll see that the thing stop charging while the case lights up.
Does anyone know if you're going to be able to kill all the Bluetooth radiation or are they going to force you to leave the pain in some kind of Bluetooth State all the time I would like to know if I can toggle it on and off
I work at Verizon and from what my Samsung rep said it doesn't have a normal. Lithlum ion battery it uses some special battery that never goes out. If it dies you can still use it like a spen. It only takes 30 seconds to charge it tho.
Cool but can the actual Bluetooth radiation from the pen and or the phone be toggled off?
im sure it will be like everything other s pen and only be on when ejected from phone

The S-Pen doesn't have a battery in it.
Instead, it's equipped with supercapacitor that draws power from the phone instantly when the S-Pen rests in the silo.The supercapacitor is capable of storing energy that provides the required power supply to the Bluetooth radio.

You can do it by keeping the "S-Pen remote" Off in phone settings.
Be noted that to let the S-Pen work as a remote, you will neighter have to toggle the Bluetooth ON nor "nearby device Scanning" ON, in phone settings. The S-Pen doesn't trigger them either. The working of BLE with respect to the S-Pen seems to be hidden.

Why would you need to turn it off?
It's not standard Bluetooth, it's Bluetooth LE which transmits at much lower power and only for like 3 milliseconds at a time.
So I have this weird issue where the the screen becomes partially unresponsive while wireless charging, like I'll have to tap an icon 3 or 4 time before it registers along with scrolling being really unpredictable. I have a case for it and it's this one. If I take the case off then the issue goes away. I am using the official pixel stand and also some wireless charging car mount I got on amazon. I found this out because I was using the car mount to charge my P5 wirelessly and was trying to use navigation but the screen was really unresponsive, after I noticed it I tried it on my pixel stand and it does the same thing. There was one other guy on the google forums who posted about this issue but no one has presented a solution yet. I just don't understand what wireless charging has to do with the screen being unresponsive and only when I use my case. On top of that the case I have is not very thick at all. My best guess is that the case I have has a thickness that is at the threshold of thickness for wireless charging to work properly so the phone constantly switches from "charging" to "not charging" over and over again and that is somehow lagging the entire phone making it seem like the screen is unresponsive. If anyone else has this issue or if others could test this out with their own P5 (with whatever case and wireless charger you have obviously) and report back that would be great.
