Ok, so I get to work and decide to plug in my phone from an old charger from another phone. I plug it in and all of a sudden, my touchscreen is WAY OFF. I hit the icons near the top and my middle icons light up.
I thought it was the phone, tried different settings, then ended up plugging in the native USB charger/cable....and all is fine.
Just in case any else runs into this issue, try the original charger.
Same thing happened to me on ny Captivate with a generic charger I purchased on Amazon.

That is a problem with the charger hitting a sensitive spot in the usb bus, this happened a lot with the hero as well when using an aftermarket charger. I messes up touch input and makes the phone unresponsive to touch altogether sometimes
Oh yeah, common issue - bad grounding I always suspected.
I've had the exact same issue. I've been using the generic charger that I used for my Pre, and the touchscreen goes crazy when it's plugged in.
It's kinda like an extra puzzle in the morning. Have to remember to unplug the phone before I can disable the alarm clock.
Here I thought I found something new....
Ah well...thanks guys/gals

Hi fellow dreamers (sorry just can't help myself), just got my dream for a few weeks, and it came only with travel charger (non-standard). I notice that when charging, my touchscreen goes haywire i.e. the touch detection goes offscreen and intermitten, it would click on icon far of the screen where i was clicking. The trackball works fine though. Would like to know if this is normal?
Oh also i've tried using my mp3 miniusb cable to connect to the computer, and it was the same, therefore it's not the charger that causing this.
Would like to hear your opinion, thanks for the help guys...
ps. dream was not officially release in my country, therefore bringing it to htc service center was out of the question (i've tried )
Are you holding the phone in your hand when you have problems? Capacitive touch screens dont work well when they aren't grounded to your hand (ie when you touch the screen while it is sitting on a table charging)

really? surely just touching the screen grounds the phone?
anyway, its always acted perfectly for me when it's charging and sat on my bedside table. get in touch with t-mobile and get them to replace it.
its a ****ty charger, the same thing happend to me when i bought a 2nd charger from a flea market, its just a ****ty charger thats all
this is happened to me too a while ago. the touchscreen went haywire after charging using usb cable to my computer. since htc dream is not officially available to my country, i ordered a new lcd screen digitizer from ebay and replaced it myself. it was complicated to replace an lcd screen digitizer, but it was worth the try. there is a tutorial video on youtube you could see on how to replace your screen. or you could ask somebody with repairing experience to do it for you.
now my touchscreen is back to normal
I found that if I use one of my non-HTC chargers (I have several from Motorola and other phones) that the touch screen would go crazy and the phone would get very hot when charging. When using the standard charger that came with the phone neither of these things occur.
From what research I did at the time, I found that the mini-usb connectors are slightly different (compare a couple if you have extras) and it's enough to cause these effects.
exactly,. but an OEM charger from htc and you should have no problems
Did you drop your phone recently? or you are assuming its due to the charger, get the screen replaced and it should solve the issue.
Just like everyone else says, it's the charger, I had this issue too, I used the charger that came with my phone and it has no issues then I had lost it (or thought I did) and got a charger from a kiosk and my screen went crazy, then I tried my friend charger that came with his phone and it worked just like my charger.
thank you very much for the reply guys, guess i'll try using htc official charger first (htc diamond's charger should work right?)
tried holding it and put in on the table, same result
dunno about dropping it, i got it second hand
About changing the digitizer, i guess since i only have problem during charging, i'll stick with it.........heard that changing digitizer is quite risky...
will post back after trying with the diamond's charger
its the charger

now just need to go buy original htc charger since i'm tired of unplugging everytime i need to use the phone
I've looked everywhere. i promise i tried to search it first before asking here.

Every time my phone is plugged in, wall or computer...swype doesn't seem to process finger swyping correctly.
anyone know why this happens and how to possibly fix this?
Are you using a third party charger? If it's not sending out the right amount of electricity it could be interfering with the touch screen (which is conductive).
I've noticed this behavior sporadically as well, with both OEM and third party charging solutions, but never when charging via USB plugged into a computer, only from the wall.
I can only speculate, but perhaps I've got relatively "dirty" (unsteady) power in my apartment wall outlets, and it's resulting in voltages outside this device's tolerances.
I've noted only the touchscreen appears to become unresponsive, this doesn't seem to have any effect on the ability for the battery to charge up.
I have this issue too when charging off my inverter in my truck. I had this on my mytouch as well. I just figured it was from the unstable line voltage. I haven't noticed any other affects from it other than that.
Agree with the others. Bad charger.
I've been experiencing this issue with many different chargers.
I've tried wall and car chargers with dedicated cables and also the car and wall chargers which give you a usb port to plug into, with 2 different data cables.
Even though the issue occurs with different chargers, it bothers me the most when it's plugged into my computer. Having it plugged into my laptop is a lot more convenient for me charging-wise.
I have no problem with any other application. I play Angry birds and homerun battle 3d with zero issues in touch screen response.
master reset of the phone doesn't help. I honestly think it's possibly an issue with swype.
I notice I need to press the screen harder when plugged into the wall for swype to input correctly. The problem is the screen not swype. You just don't notice it with other apps because of the need for less precision.

It's not that. You know when your texting, the swype "trail" is smooth, when it's plugged in, the lines get jagged and the phone picks that up instead of my original input and trys to guess the word off of the jagged line.
This happens to my phone and I always assumed it was heat related. This does not happen to me with the original samsung charger but on my cheap ebay wall and vehicle charger it does. Samsung charger is .7 amps and the others are 1 amp.

have anyone got issues with S2 when plugged into power?
ie when I start recharging direct from 240V adapter, my S2 started getting VERY laggy and slow.
It immediately goes back to normal response when I unplug power.
I have never problem like you

Try using an alternative charger...probably your mains charger or the usb connector on the charger is damaged.
I'm pretty sure its a issue with the s/w as I have used the charger on another phone without any issue.
unless its one of the apps I'm using, not sure how to narrow it down.
mtrax...
I have the same issue.
You´re not alone...LOL
FYI the common issue I have when plugged in is that its not easy to unlock screen, takes me a 2-3 swipes to unlock screen and after that it seems that it ignores every other key press..
Any one reported this to Samsung? I will try to log a ticket to see what happens.
Try do a multi touch test while its plugged in see if the screens acting funny.
how do I do a multi-touch test?
what will that prove? as the screen works fine when unplugged.
I have the same issue but only when charging with the usb lead (with usb power adapter) instead of the standard mains charger. Think it might have stopped now that debugging is enabled and the Samsung kies screen doesn't come up when i connect the usb.

Took my phone 2 hours to charge from 36 % to 100 %
note this issue doesn't occur when charging via PC ONLY via 240V mains, but let me try with USB debugging on.
edit tried USB debbuging still has issue.
Note is the 240V USB cable different from a normal USB cable? ie perhaps the device thinks its a PC connection
the phone is laggy because of the electrical interference from a faulty charger or some other electrical equipment in the near vicinity...
Please note that actually the capacitive touchscreen becomes laggy not the applications/services...
keep it away from the electrical interference...use the samsung original charger..gud quality USB cable....and the issue will be gone... for sure
looks like its the charger, the A/C adapter I got with the phone was UK which is why I didn't use it to begin with, but tried the samsung one with a UK/AU adapter and its fine..
hmm who would have thought that was the issue...
interesting it didn't affect my other HTC phone.
Same issue here, but something special:
I ebayed another charger for my sgs2, original samsung one. Same serial number, same description, same style.. but i got the charging problem only with the new one.
With my original charger (the one, which was delivered with the phone) works fine. No slow and no lag.
The new one was about 5 euro, seems to be an original...
to demonstrate my point that its the electrical interference from the dodgy chargers onto the capacitive touchscreen... do this and report back...
plug the faulty charger onto the socket BUT DO NOT charge the phone with it...
keep the phone near to the charger wires etc....(not in charge)... you will see the screen lagging sometimes unresponsive...
now move the phone away ...it will work fine..
you can keep on using the dodgy chargers for charging...but use the phone only after it has been charged and is away from the charger...

I am not able to reproduce that with my original charger. There is no lag or any other problem. Switching to my second "original" (ebay 5 €uro) samsung charger leads me direct to the lag and your description. First i thought my second one is not an original one, but because of your description there seems to be a diffrent quality on the original charger depending on it production date.. unit.. charge.. or whatever.
I bought a sgs2 from the UK, and have a UK to AUS converter on the stock charger and I have no lag when it's charging or near chargers.
Sorry. Not a problem here. Writing now and plugged. Very responsive.

The electrical interference with the capacitive display is bullcrap since it needs electrical properties to respond. So it depends on whether your body has enough electrical properties.
So back to the point:
It is due to CPU reducing the clock speeds to prevent the phone from overheating as the battery itself produces enough heat anyway.
Many other people may not notice it since they may not perform intensive tasks while the phone is plugged in and the variation itself is also almost unnoticeable.
I have the same issue but as I said, it's almost unnoticeable to even bring it up in this forum. I haven't done any testing myself to prove this, but the same safety feature is implemented in most modern phones.
I have the same issue - I also had this issue with my Atrix.
Hi i just got my xperia play and noticed that it is almost unusable when im charging, the keyboard will hit random keys i cant scroll from the main screen etc. But as soon as i pull the charger usb out it functions perfectly, anyone know whats up?
I've noticed something similar, the accuracy isn't as good when the charger is plugged it. Are you using it with the pad out or not? try with the pad out and see if that helps, otherwise it may be a hardware fault
I use it while it is charging all the time. It works perfectly.

I haven’t had any problems using mine while plugged in.
This is not that uncommon as one would think really. Capacitive touch screens may react different and most of all less accurate when plugged in to a charger. Try using a different wall socket when charging and you'll probably notice some difference to this behaviour.
A grounded wall socket is usually better than a non-grounded one.

i had that in my iphone your charger give the device to much voltege and its creeping up switch to a diffrent charger and a cable and see if thats help (and it will)
I don't know if anyone else is experiencing this, but I've discovered when my Nexus 4 is plugged into my laptop (a Macbook Pro), the touchscreen kind of acts a little wonky. Occasionally it won't completely pickup my drag (like when I'm unlocking the phone) or swiping between homescreens. Has anyone else had this problem? When the phone isn't plugged into a computer it runs just fine.
just tried it. My phone is running smooth, even when i plug it in to my computer. are you running custom Rom?
Its stock ROM and kernel. I'm running 4.2.2 but I believe it was also an issue in 4.1.2. I'm just trying to figure out if this is something I should RMA over.
Have you tried to use a different cable? I have experience the same problem and was able to fox it using a different cable or a different USB port.

That's good advice, thanks! The cable I'm using is not the one that came with the phone, and could be suspect. I'll give it a shot.

That's probably what it is. My old Motorola droid cable used to do this to touchscreens.

Note: As per my observations, the touch threshold changes when charger is detected. This affects the touch sensitivity.

My girlfriend bought a cheap charger from eBay and it caused her screen to go haywire. It started pressing random things. I plugged it in my Samsung Galaxy i9000 and the touchscreen simply froze, you couldn't actually press anything.
You'd be surprised how dirty current can damage/affect the running of an electronic device. New cable and/or different port me thinks
Same problem here
Hey, TrevSo, I have just noticed exactly the same issue with my Nexus 4. I connect it to one of my laptops and the screen goes all wonky ... poor sensitivity, phantom taps ... very strange.
I have tried several different cables and tried it on two different computers and three different chargers.
any cable with any one of my chargers (included one, some Kodak charge and an HTC charger) - OK
any cable with ThinkPad W520 - OK
any cable with Thinkpad T60 (any of the three USB ports) - BAD
Maybe a grounding or insufficient power issue?
EDIT: definitely a power and/or grounding issue: my T60 came with a cheapo aftermarket power adapter. When the power adapter is plugged in, the phone's screen freaks out. Unplug the laptop to run it on battery power and, voila, phone screen is fine. I looked it up and the official Lenovo adapter is grounded.
I have experienced the same thing using the stock cable from my Galaxy Nexus connected to my ThinkPad X60 laptop. Swipe gesture typing will cut off my swipes mid-word and the double finger swipe gesture to bring down the quick settings menu will lead to unintentional taps of things on the screen.
Same thing happens when phone is connected to an Asus netbook using the stock Nexus 7 cable.
4.2.2 didn't fix the problem.
Hey everyone, thanks for all of the feedback/ideas. As others have surmised, it appears to be a charger/cord problem. I ran a couple tests and it really seems like when it's hooked to my laptop (while plugged in) using a non-OEM wire the touchscreen acts really strangely. When hooked to my desktop, things seem to work just fine. I'm no expert in these things so I can't really make a conclusion based on those facts, but I hope this information helps other people.
Yeah, like I said, definitely a power source issue. I guess some laptops don't deliver quite the correct voltage to the USB ports or something.
