I've had the phone since Monday. Last night, now that we have a stock kernel, I went ahead and rooted my phone.
Today, on three occasions (requiring reboot) my phone had what I can only describe as a touchscreen freak-out. The image twitches and jumps around even when not being touched. When it is touched, it's entirely unusable. Apps not even close to your finger open and close with a quickness. I've already sent a few very fun swype text messages, as you might imagine.
I migrated from the OG Epic and never had any issue like this. Lack of responsiveness when dirty, but not total madness. Has anyone else had anything like this happen? Is it just a matter of needing to get a new phone?
Thanks for any advice!
Were you plugged into the Samsung wall charger with the Samsung provided cable at the time?

Happened to me today too. It was the OEM HTC EVO 4g charger causing it.

So this is a known issue? I hadn't seen it mentioned before.
It's a known issue. Some people claim to have good results with a different cable, some with a different charger. One theory is that the wall charger is over-rated and that extra juice is making it go wonky. USB charging doesn't seem to be affected by it. The effect seems to decrease the closer to 100% charge you get. It's a known problem on a wide variety of devices from a wide variety of manufacturers and aside from your cable and/or charger your own local power may have something to do with it. A software update can fix it as it has in the past on a wide variety of devices. Not everyone has this problem all the time. YMMV
I would suggest buying an OEM blackberry charger from Amazon for like 7 bucks. That's what I used on my epic and what I'm using now on my epic touch. The charger that came with this phone is still sitting in the box.

Hmm, I've had the problem with different chargers other than the one that came with the phone.

I use an OEM blackberry charger and still get the freakout
I've been using the charger that came with a bluetooth ear piece, and I have no issues whatsoever.
Although, I normally charge through USB.

So when the unresponsive screen when grounded issue came about, I didn't really notice the problem much myself. However, recently, and I'm not sure when this started, the screen has become horribly unresponsive when charging any time! Doesn't matter if it's on desk, in my hand, stock charger, 3rd party charger, etc., if it's charging at all, the touch screen only accepts half or less of my inputs, making typing impossible. Is this due to the last software update? Anyone else experience this issue? I would exchange the phone, but not if it's not going to help anything.
this happens to me when i use my cheap ebay charger
The fps lifting kernels fix this.
+1 for symtoms seen when using a wonky charger/cable.
+1 due to cheap charger - anyone know why this happens? is the OEM usb cable different spec from the cheap ones?
Hate to beat a dead horse, but the same happens when I plug my phone into the charger I got from eBay. Kind of disappointing, considering that I would otherwise be able to charge two batteries at the same time.
I notice this issue with the stock charger.
I believe the issue was when its not grounded..
Being plugged in is just about the most grounded your phone can get.
That's not the problem.
Starting to do it to me also now.
Just to be clear, this happens to me with the STOCK charger.

I'm having the same issue. i just chocked it up to the new kernel.
one thing i did notice is it seems to be intermittent. Yesterday night, it worked fine. this morning(conveniently when my alarm went off) i could NOT get the dismiss thingy to slide down.
Anyone else experiencing this? I do think it got worse after last software update. Would be nice if the next one improved things.
I emailed support, they did not say anything about it being a known issue, and suggested a factory reset. If that doesn't help, they recommended using my warranty. Would like to hear from more people before going through with the reset.
It happens to me when charging via outlet. Charging via USB connected to computer does not produce the issue.
I think it has to do with grounding.
Same thing happens to me! I noticed it with my aftermarket wall charger.
Bringing this back up, happens to me with a Stock charger.
Is it really the kernel? :\
@Person who said charging is the most grounded, the stock charger is not grounded ( in AU anyway ) and therefore it is the LEAST grounded.
ive noticed this happening over the past month or so. i've got to admit i've only really noticed this when its plugged into a usb cord i got off ebay. relieving to think it might only be an issue with it being a cheap cable and not the phone but i'll verify tonight with the stock cable.
I've been plagued by this problem for weeks and just discovered that it only happens when charging. I use the stock charging cable and wall adapter. I'm very, very happy to know what the problem is. I'm going to start testing this at various locations.
EDIT: I've tried this on both the wall adapter at work and on my work computer's usb. Same problem, though it seems worse when plugged into the wall outlet.
The touchscreen is fine on my sprint brand car charger and on the usb charger on my laptop. However, it starts missing taps when I plug my usb cable into my usb car charger. I'm going to best buy tonight to buy a different charger and see if that helps.

I have these issues as well with the stock charger and cable regardless of which kernel I use.
This isn't a problem but more of just a general question. So does anyone else experience your phone kinda lagging or having screen sensitivity issues (have to press hard on screen to scroll) while having the phone charge? This is like a 50/50 thing sometimes it does this sometimes not. So post your experiences with this
Sent from my PC36100 using XDA Premium App
Yes indeed. In my case, it's caused by my HTC USB cable that came with the phone. When I use the charger from my old LG ENV3, i never get that problem at all. As soon as I switch to the HTC cable, it's nearly un-usable whilst plugged in. It's odd, because the HTC cable works fine for charging and transferring data, so I don't know, but there's something wonky with it.
Hmm interesting

Nope, you're not. It can certainly become rather annoying if you're trying to use your phone while it's charging.
Yea, using swype is IMPOSSIBLE when plugged in.
I never used to have this problem before, so I wonder if this is something that comes with age of the phone. I've run all kinds of roms/kernels and never had this issue until maybe a month ago. But I think I've successfully narrowed it down.
You need a charger that outputs 5v at 1000mA. Any more or less and you'll get the wonky response. I have an 800mA and a 1.5A charger at 5v and I get the laggy response. And I took it a step further and noticed that I get maximum charging speed (regardless of kernel, I've tried stock and custom/SBC kernels) with a 28/24 AWG or 24/24 AWG micro USB cable. If you still rock the stock HTC charger/cable combo you should be golden.

i don't think its from age of the phone because i just got my phone in december (hw 0004) and i am still using the stock htc charger/cable. so idk its a mystery. nice work finding all that out tho its good to know that i am not the only person who experiences this haha.
I only get the problem when I'm plugged into A/C power, but not when I'm plugged into the D/C car charger... I think it has something to do with how the outlet is grounded. Maybe the touchscreen gets confused by getting grounded through the charging port rather than through your body. I'm basically making this up based on hazy memories from an E&M class I took about 8 years ago, but I think it's close. Anybody with any actual knowledge care to correct me?
Plugged in my Epic Touch to charge today and it wouldn't charge. Used a few different cords, and different outlets. Then tried my HP touchpad charger and it worked. Looks like I got a bad wall charger. Although, it was working last night. Anybody else?
Now that I've tested it some more, it's just REALLY finniky about being plugged in. It has to be plugged in at the perfect depth, somewhat at an angle even. Anyone else notice this? Bad charger?
Got my phone through Wirefly... surely I won't have to return the whole phone just to have this replaced?
I wouldn't even bother assuming i had another charger. The block Samsung charger looks just like the Hong Kong ones from ebay that you can buy for 3.99 each.
Well this one is supposed to be "super duper fast charger" so what kind of numbers (ohms/amps/jiggabats) am I supposed to look for when buying a new one. I know last night I had it on my old Epic charger and it took over 4 hours to charge to 100% from 82%.
Also, I know it's been mentioned before, but this thing is UNUSABLE when it's plugged in to charge. at least with the stock charger.
My samsung charger makes the phones touch sensitivity go thru the roof. Opens applications and menu's and carries out commands and such. It also creates lag switching between screens. Not an issue when I have my HTC Evo charger hooked up to it though. I'm just exchanging the whole phone and charger combo to be safe.

Really? I haven't even opened my stock charger and cable because I have so many others but I'm using a wall charger only with a Sprint label on it (got it doing some phone trading along the way) and the phone flies just like it does not on the charger.
The one that comes on the box gives the phone the major blues while charging

This is horrible news ... my epic charger is half broken..
Using a HTC charger and it works flawless I wont even try to use the Sammy ones especially for DLing roms or for odin
Alas my sammy charger does not work either. I walked in to BB and they handed me a usb charging block branded HTC, since they didnt have any epics left.
Yes but what about speed of charge? The stock charger is supposed to be a quick charger.

Like I said in an earlier post, I haven't even opened the stock charger...so you can't use the phone with it charging with the stock..its that bad?
Both mine AND my girlfriends gs2 have this problem. When the phone is charging, the touchscreen is not reading the correct point of where I touch. Anyone else having this problem?
Yeah we all are. There is something wrong with the square adapter that came with the phone. Try plugging it into a PC to charge or using a different adapter. It works fine.
I noticed this as well, but only with non-OEM adapters.
And I thought it was only me. Get the same problem only with cheap chargers.
OEM, MT4G, Transformer, Touchpad, Galaxy Player, Ipad & iPhone chargers all do not experience the problem.

I don't and I also have this problem.
I believe its the square Samsung charging adapter.
Powered by the SGSII....
Ditto here, it behaves Ok when charged from my laptop, PC and Motorola charger (came with my Milestone), but definitely quirky when charged from the square little adapter that came with the SGS-T989D.
Add me to this list as well.

Same here, but it does change when I use another Samsung adapter like the one from my Vibrant it'll actually work once i use that one.
I have the problem with non-oem...oem is just fine for me
This is happening to me. I am using a Quikcharger for Samsung which I bought from Sears. Anyway to fix this? Because the OEM square charger + data cable is to short to use in bed.

it only happens with defective charging cables
how i know?... i just accidentally crippled a pin of my existing charger, and now even though it still charges, it causes all kind of random weird things in my phone.
so i simply stopped using it, and changed to another charging cable

This is a known issue with the SGS2. Any inconsistencies or issues with the power supply via AC will cause the screen to tweak out. Possible causes are a bad cable, bad power source (outlet), or improperly inserted microUSB connector. If you try a number of times and cannot get the cable to connect properly, return it or get a new one.

Me too
I just started having the same problem. I use to be able to use my phone while it charges and it would charge fairly quick as long as I wasn't heavly using it. Now even when I'm not doing anything on it, its charging ridiculously slow.
I thought it had something to do with my recent flashing of 4.3 but I flashed a MC2 restore and it didn't seem to matter.
Get the Galaxy Charging Current app. It will let you know the charging current. It should be *Now: 1698*. Mine would read 466 and I would reinsert cable(until I got a new charger/cable) until it read 1698. It appears there is a problem with OEM cable.

Been working great for ~3 months on my Sprint Note II. It said that when I downloaded the app too. Try the free version, I like it and bought the app for the dark background feature.
I would try another USB cable first. I was having the same issue. I tried a different cable I have around, and was charging like I was expecting. So, I order two premium USB cables from monoprice.
From the reading on XDA around here, it looks like the USB cable that came with phone get shorts in them fair easy; ie they're not very durable. For me, no biggie since I like to keep cables in various places--car, house, backpack, go to bag, etc.
It changing the cable didn't work, try a different charger. If that doesn't work, try the battery. If none of those work, then it's probably your USB port.
Although, the USB cable is most likely the issue.
If you've had the phone for awhile, try cleaning out the microUSB port on it. I used a toothpick and picked out a surprising amount of lint that had accumulated in there. It may help establish a better connection between the cable and the port.
Definitely seems to be an issue with the usb cable, I had the same issue, switched cable, and all is fine.
