A friend was at my house this afternoon charging his Galaxy at my bar. A call came in, so he unplugged it, and the phone immediately disconnected the call mid-ring.
After he called back and finished his call, we did some tests using my home phone and were surprised to see that both of our phones do this.
Has anybody else seen this? Seems like a pretty silly flaw.
Nope. Ive unplugged mid call on all three charging sources (USB, car, AC) while talking and have never dropped on. Very strange bug you've encountered. Was it with the same charger or different chargers? If same then maybe something with the charger?

He may have hit a button in the side while unplugging it...

No accidental button presses, as I said, we tested this so we paid attention to what we were doing. Two different chargers, two different phones -- both using the stock Samsung chargers.
Note that this happens during the RING... not mid-call.

I haven't seen anyone else post this issue, but I have 2 vibrant's. One completely stock, the other rooted with ZA lag fix.but when either one is on the charger (or charging via pc/mac) the phone is very slow and choppy. Does anyone else have this issue?

I have seen this issue but only with non oem samsung vibrant chargers/usb cables. I have one that makes my phone completely unusable and another that makes the phone respond on its own.
The charger that I use every night is the one that came in the box.

I have this exact issue on a stock vibrant i got this morning. I was surprised that this was the only place i saw this mentioned; which lead me to register at the forums.
The touchscreen becomes less accurate i think; when flipping through app pages it will often open an app accidentally if the charger is plugged into the wall. havent tried from a computer or car yet.
It not bad enough of an issue for me to return it but it is a bummer. If anyone finds a work around i would be interested.
This happens to me with the stock wall charger too but only when I have it connected to a source converter, more specifically a vehicle outlet power source adapter: Duracell 175 Watt DC to AC Pocket Power Source Inverter.
I didn't try and see if I only connected via USB to that device if it still was the same. But I do know it is with wall charger to the outlet on that particular device.
Now other than that device, I have not experienced this issue or the few times it was plugged into my computer.
But I do know it is annoying when the problem occurs, even though it is easy to disconnect and then use real fast or do what you need to do and then reconnect, it is still an extra task that has to be done.
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
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.
Hello everyone I have a couple issues here...
Charging
When I use my stock Samsung S5 charging cable, sometimes I will get a slow charge, others a fast charge, and other times the phone will act like I am disconnecting and reconnecting my cord rapidly. On rare occasions the phone will even act like I never plugged it in. This is using multiple power sources to try to charge. Yes, I know it could be the cord, but before you reply, read the next few sentences.
I recently purchased new OEM cords from eBay as well as some OEM Samsung S4 cords (for my wife's phone). I've tried the new OEM cords and the phone did the same thing. When I try to use the S4 cords, along with other microUSB cords, I am experiencing the same problems... sometimes these cords charge the S5 faster than the OEM S5 cords!
The strangest issue I am seeing so far is now when I plug in using a normal USB from a 12V or AC charger I am getting a box that pops up saying "Advanced Power Sharing" and asks me to go to the Samsung market to download it (I'm assuming its an app).
Receiving Calls
I drive a truck for a living, I depend on calls coming in properly. I'm also married, so the importance of a working phone shoots up about a million percent However, she says she calls me and my phone doesn't ring, and doesn't alert me of missed calls. Other people I talk to experience the same thing when they try to call me. I know this is a network polling thing but since it's intermittent I am not sure that the network polling is really the issue here? (FYI I do not know where to look to edit network polling frequency.)
The charging problem soubds like you've got a bunch of crap in the charging port, i would try and clean it out as best you can.

Charging port area is clean as a whistle. I'm thinking I am going to need to replace the port.
