so whenever i charge my evo my phone's touch screen starts flipping out. when i try to draw straight lines it seems to create a zigzag pattern instead. I noticed this in swype when i was texting while charging and it would zigzag around causing me to input incorrect words, does anyone else have this problem?
PS. its not just in swype its overall general touch input
Yup. But I only charge at night when I sleep so I don't care.

Try keeping contact to the kickstand with some finger of the sliding hand. I find that my little finger keeps capacitance constant, and alleviates the jitter. Want to see weird hold the phone in both hands and sporadicly touch fingers together while sliding across the screen.
The power control module slows up response time and the touch screen gets too skewed without self correcting.
Mine use to do that with cheap non OEM chargers. Try another charger

its a stock charger.
glad to know i'm not the only one experiencing this though
Since I thought my phone, I've noticed an annoying problem. When my phone is charging in the screen is locked, I go to unlock the phone and the touch screen seems to have a problem registering my touch for the pattern password.
I would unplug it for a second to draw the unlock pattern, unlock the phone, and then proceed about while the phone is plugged back in. Then out of nowhere, it'll do the same thing.
Anyone experiencing this?

There is another thread here somewhere that talks about the issues while being plugged in. I think this was one that was mentioned.

i am not getting that problem, but if you call tmobile im sure they will switch the phone.
I've had this problem - but only when I used a different charger from the one included (even though it's a Samsung charger). Are you using the cable included with the phone?
Yea it has happened on mine but only if it was laying down when i try to unlock it. once i pick it up it was fine

I can confirm this very issue on two GSII's I've used. It's annoying.

This is a known issue with all variants of the Galaxy S2.
The Galaxy S2 is very sensitive to input voltage, and if it doesn't like what it's getting, the touch screen calibration gets a little funky.
Voltage-regulated chargers (ones that are big and blocky or have a bulb on the wire) tend to work well.
Don't bother exchanging it over this, it won't change anything. You just need a better charger.
Yes, I'm using the same charger came with the phone. I guess we will just settle this issue with the fact that it just gets a little funky When plugged in.

better charger yes
phone being sensitive not really
all Properly build chargers will not cause that problem
i purchase cheap 2A charger from Deal Extreme, but those are build good, not like some of the crappo accessories from ebay
BlackBerry chargers works good too
I have the same problem.
As many of you guys said, a good charger is needed for a stable voltage input.
I have no problems charging from the original charger and my desktop computer.
However the problem shows when I am using my laptop (7 year old) usb.
So a good charger is recommended.
I can confirm this issue, but what i want to know is, why does this happen when the phone is lying flat on a surface while charging and goes away the moment you pick it up? If it was a faulty or imprecise charger issue then the problem should persist?
My guess is it has to do with the EM shielding around the charging module, and that it doesnt do enough to shield the totally normal residual interference from interfering with the touch screen digitizer. When we pick it up, our hand acts as an interference dampener and minimizes the issue while it is charging, to almost negligible amounts. But its just a guess. The chargers might also be generating greater than average interference as well. But just charger alone cannot explain why pickibg up minimizes the problem.
The charger doesn't cause any erratic behavior on my Galaxy Nexus like it does on this phone... So what is the explanation behind that?

Use the charger that came with the phone

What's unfortunate is that the Samsung charger that came with the device causes the touchscreen issues.
Fortunately, I have an HTC charger lying around that works, no problems.
I have seen this happen with the HD2, Evo 4g, galaxy s4g & Sensation. Its a problem with chargers and the voltage. It happens with those chargers from walmart. Its not just the GS2 phones.

Add the Tmo HD7 to the list.... it happens all touchphones on which i believe has grounds surrounding the phone, touching the touch screen stabilizer or whatever you'd like to call it. It's the ground of the charger, nothing to do with charger instability. Take your laptop's charger, plug it into a wall with no 3rd ground (a laptop that has the 3rd prong) and take that same plug, and plug it into a plug with 3 prongs, you'll notice it has that static-like feeling that makes ur fingers tingle (when you touch a metal part of your laptop). It's the same issue with our phones
I hope this helps someone
Just change charger i have noticed that since i work in a cellphone company .... but i change to a different charger and it stopped doing that....
I used another charger but the problem still exist
ive been running calks roms ever since he released them for our phones and i have never had an issue... that being said, i flashed his latest 2.0.1a and was working fine up until yesterday... it seems that my menu button presses randomly for no aparent reason! i cleaned the screen to remove any smudges it may have and that doesnt help... do you guys think its the phone!? like i said the roms have been working fine! i even flashed it again just to check and no go...
Sounds like a problem with your phone unfortunately
Sent from my SPH-D710 using xda premium
also - search Calk's ROM thread for anyone else that might have the issue, a fix or replace suggestion.
Yep sounds like hardware, did it continue after a reboot? Sometimes a system reboot complete with a battery pull can fix little glitches like this.

Pull the battery a leave it for a few minutes, then put it back in and see if your problem goes away. It does sound like a hardware thing.

I've been getting the same thing and managed to catch my phone misbehaving on camera.
I am sure it's hardware as when the problem started for me i was on a stock room that I simply rooted. Thinking it may be something with the rom (like you) I flashed a whole new rom with a whole new kernel (blazer rom with the ek02). the problem persisted and thats the setup I was running when I shot the vid. yesterday I flashed the stock EL13 rom and kernel. same problem.
Let's compare notes and see if we can narrow down the list of causes.
1) it's not rom related.. but MAY be root related. thoughts?
2) I recently damaged my stock charging cable and started using a cable (samsung brand still) that I picked up from amazon... could that be the issue?
3) on the FIRST DAY when I bought my phone, i noticed that the screen goes haywire if I try to use it while its charging. this only happens on the stock charger. I was told by members of the board here that this was normal and dismissed it. could this actually mean that our phones were defective to begin with?
Lets here your thoughts.
btw. I'm having my device replaced on friday. if you have the equipment protection plan then it's free of charge.
As ironic as it is, i posted on this thread just to try and help and be it as it may my phone is now doing this now... its done it about 3 times and its annoying lol
Edit:I'm on blazer 2.0 with desperado and el13... but it did it on ek02 too so its not the modem

so far I'm thinking it's something to do with bluetooth, the headphone jack or third party cables.
anyone else using headphone or a tape adapter at the time this started for them? what about simultaneously while listening to bluetooth?

so is yours completely random or does it seem to happen only under certain conditions?
Got my new device last night. One difference ive noticed is that this one actually charges fully (battery shows 100%) even off of the charger. My previous device dropped to 99% as soon as i unplugged it.
The screen calibration still goes haywire if used while its charging.

is this rom related
I am using calks 2.5 with rogue kernel. my phone seems to have little lines moving up and down the screen. I just got this phone after turning in my other one because of hardware problems. just wondering if anyone else is experiencing this as well.
Well, it seem every phone I use in last 6 month getting this disease when you swipe or touch on screen and nothing happens, or when you press one key on keyboard and it inputs completely different character from opposite side of the screen...
Just now I had the same exact crap going on on Nitro!
I pressed and hold on back button on the gb keyboard and it was acting like I'm pressing random keys at 50 keys per second!
But before that I had trouble unlock the phone, since the slide off motion didn't register at all, the slider would move a few pixels and go back.
The weird fact is the most noticeable this occur when phone is plugged in and charging, unplug it and problem usually goes away or at least become manageable.
What the hell I'm doing to these phones that causing this? Actually this is the first phone where I f.k with the system files, all others I either used CWM or market, nothing else.
I have not had any touch screen issues with this phone other than its just a hair less sensitive compared to my captivate.
[email protected], are you a ghost? I have heard that sometimes phones will act strangely during use if you are a ghost. Something to do with spiritual electromagnitism. This would also explain why you are having compass issues!
Okay, so back to being serious. I've had the EXACT same issues you speak of when my phones (yes, this has happened to other phones too) were connected to 'dirty' power.
What I mean by 'dirty' is either a power supply that was very low quality or using a USB cable that the phone didn't like. Just recently my Nitro was acting erratically while I have it plugged into my computer. It shouldn't have been a problem because I was using a high quality, well shielded Blackberry branded cable (worked perfectly fine with my Nexus One), but as soon as I used the usb cable that came with the Nitro then everything worked correctly again.
Hope this helps!
i had that promblem today ... but nothing i did fixed it so i was able to pull the battery and do a dreded hard reset and its working as good as gold now

Just got the same problem. Tried everything listed here to fix it. No luck.
Any other suggestions ?
I've found what Namuna said to be true. Also, I experienced this issue with my phone plugged into the power strip on the nightstand. Apparently there is a grounding issue in that power strip.

Could be it. I use a power bar also. Plus I think I'm using a cable from a galaxy nexus now that I think about it.
Maybe I'll try to find an official lg cable.
Thanks again.

I haven't had a complete loss of touch responsiveness, but I have experienced the erratic behavior; but only when plugged in and only while charging in AC mode. I've noticed this a lot more since I dropped my phone with the charging cable attached... I can be in USB mode and the slightest touch will knock it off charge yet I have no touchscreen problems. Once, every now and then, I am lucky enough to get into fast charging AC mode; which is much more stable as far as touching and using while charging... but the screen is almost unusable due to the erratic touches. I turned on "show touches" in developer options and while in AC mode, it shows multiple touches in a horizontal line relative to where my finger is. It even affects my soft keys.
Happens with every charger I've tried; my original charger, both HTC chargers I have, and a charger I found a few weeks ago. I've experienced the problem in my house, multiple hotels, and a few other places; both with and without a power bar. Pretty much, what I'm saying, I'm sure I've been connected to a good grounded source of power, yet I still experienced those problems.
Out of curiosity... have any of you either replaced or had your digitizer replaced? I've replaced mine twice, and my problems began shortly after cracking the screen the 2nd time.
Well i tried the charger that came with my optimus g (using a power bar ) and it seems to work fine now.
One more thing i did was try it without my memory card for a bit. I don't know if that had anything to do with it also.
Anyways so far so good.

Hi I am using the ICS leak and sometimes when I plug the micro USB cable to the phone and other end to the wall the phone does not charge.I have tried multiple chargers and the only thing that fixes it is rebooting the phone, but recently at times that does not help. Does anyone else experience this? I am thinking charging may be controlled by the ROM and I may switch to something else.now I am only hopping it is not hardware but I do know it is slightly buggy connecting to the computer. This is why I am asking to know if anyone else experiences charging issues.

I haven't experienced any charging issues. It might actually be hardware related which sucks.

I had the same problem on GB plus my volume key on the bottom side didn't work. But a couple of days later, I dropped it hard by accident. Everything was back to normal. Not saying you should drop yours intentionally but my phone had so many problems and yet still love the thing.

I think it's the microusb ports that are the culprit as I had similar issues with it that included connectivity issues when trying to update to ics. I had to "hold the phone" with one had & the cable with the other to keep a stable connection to get it to complete.

My microusb port is really loose and the cable moves and pulls from side to side a lot. Haven't had charging issues yet though. Hopefully I never will.

I think it is hardware,I push down on the connector when plugged to phone then it status charging.but once it starts no movement stops it.must be 1 contact that is not being made to initiate the charging.
