I wonder if someone has the same problem on his X10.
Almost everytime when I am charging the phone through AC i am not able to use my phone!
It just acts like CRAZY! When you try to slide thorugh the desktops, try to open an app etc. the phone simply does whatever it wants! It opens apps, it slides the notification bar down and all this at a really high speed!
Contacted Sony a month ago about this, but of course NO response on this!
Tell us more info like: R u running any ROMS or what firmware r u running from se? This could b a hardware issue or a ROM issue, software issue.

This same thing happened to me with a cheap charger from eBay. Would I be right in guessing you are not using the official charger?
It does not occur with all 3rd party chargers though, I have used others that work perfectly.

Hey thanks for the quick responses! I am using stock firmware 2.1.A.0.435...arc launcher...so nothing special I guess..
My charger is an original sony one...I have another one though so I can use this one and see if its a charger issue..

Have u tried flashing a new firmware from se with flashtool from the x10 android developement section.
You can also try the se software SEUS on the computer and hit the repair button on the update option.
Both ways will delete all data on phone though. But could make your phones software start fresh

Hey there! I had the problem before I flashed my phone with the flash tool and the latest sony update aswell...
Everything is fine when i charge through PC or Car, so either there is something wrong with the AC charger or....seriusly i dont know...

Check your charger voltage out put, usually it MUST remain like 3.6-3.7 volts, more than that you gonna have that happend.
last time im try to modify my charger to make it more efficient by using the 3rd party unofficial cheap n lousy charger, and i try it, more than or less than 3.6-7 (if im not mistaken, its a long time ago), then your capacitive screen will sense the leak electric then it just go like ghost finger.
In short, check your charger voltage again, it must be precise in certain amount of voltage, cannot too much or less.
Hi just measured the voltage output and it is 5.20 volts
What Do you thing? I thing its ok since the pc is also giving 5 Volts

display problem while charging (BST-80)
I have got it the same with my X10 mini and my new charger that I bought today - BST-80 (original SE).
My stock SE charger that came out of the box with the phone was EP800 (5V, 850 mA), but it looks to be damamged or defective (some weak noise I can hear going out of there).
This new one BST-80 is 5V, 700 mA. But I do not think that it can have anything related to 700mA vs.850mA (this should be related just to the time of charging from empty to full - 700mA should last longer than 850mA).
Anyway, I am also quite frightened of what it does to my phone. The touch screen looks to behave totally confusing. Once I unplug the charger, everything gets right again. Then I plug in again and the confusion comes again. So weird.
I have never experienced this with my former charger for whole one year of use. Both of them are original SE.
Mate, did it damage your phone in the end or not?? Did you solve anyhow?? Thanks.
Hi,yes I "accidentally" used a micro usb Motorola charger ,one that has its cord attached and you can't remove it like the SE ones and I haven't had any issues at all!It seems like it has been a charger problem after all!A real weird one though! I have 3 different chargers and all caused the same problem!I've tried my girlfriends x10mini with my charger and it caused the same problem!
Now I am good with the Motorola one!;-) Hope it will work for you as well!
Sent from my Iphone-KILLER/cracked [email protected],2Ghz/woooooohh suck on this biatch!!
I returned that SE charger back to the shop and waited for another piece, which would not be defective. Anyway, the new piece had the very same issue with the touch-screen. But in the meantime I tried out another micro-USB chargers from that shop - LG and Nokia. They did not have the "touch-screen" issue. But I ended also with Motorola charger, as the best choice of them. This one doesn't seem to have any issue - touch-screen works fine while charging, it doesn't produce the "buzz" sound like some another chargers do, moreover it has also 850 mA, which is the highest current I encountered while trying those chargers (they had only like 550 mA, 700 mA, etc.). So I am quite satisfied in the end. Thanks.
I downloaded touch test from the marketplace and discovered that whilst im charging my my phone the points on the screen jump all over making the phone very difficult to use. Anyone else have this problem or know any fixes?
This is my first ever post sorry if im doing it wrong, go easy on me.
My phone is HTC Mozart running mango. Any help is appreciated thanks.

Happen to me too, when using:
- Wall plug USB adaptor
- Some wall plug charger
It's Okay on PC's USB though.
I think its because when your phone charges it gets hot. As the phones use capacitive touch screens which detects heat, it detects the heat from the battery and it goes all over the phone. Thus it goes haywire. This is what I think and I don't know if its correct. Hope this helps

Erm i thought that capacitive touch screens worked from electrostatic energy getting conducted though finger tips. Rather than heat/tempretaure. So i dont think the temperature of the battery would affect it. Im not an expert but thats my understanding of it correct me if im wrong. Ps i dont mean to sound like a know it all.
I have the same problem. HTC Mozart 7, using wall charger. Australia (so 240V).
I do not think it is a heat issue, as the problem starts immediately, and there is no sign of heating.
With one charger, the touch screen does not respond correctly .. touch one place and it act as if touched somewhere else. scrolling jerky etc.
With another charger, the reaction is worse, the phone behaves as if someone where pressing, dragging, pinching etc at random over the screen. If will exist apps run other apps, etc etc. So I have to turn it off while charging with that charger.
No problem with a PC (or other device) USB port.
I imagine that there is something causing a build up of charge. Because it is ok with PC USB, I don't think it is a short in the phone or cable. *Perhaps* is may be related to the DC from the charger not being clean (ie not a steady 5V, but varying at the 50/60hz)? Or maybe the voltage or amperage is too high/too low.
But I'm glad to see its not just my that is suffering
Hopefully someone with the technical expertise can at least tell us
1) what is going on
2) is it harmful to the phone
3) is there a fix.
Fix : open charger and put a high voltage (1kV+) not polarized capacitor (Y1 (ceramic!?) - I saw some schematics with 2.2/4.7n) between the "-" of the 5v (output GND) and at the "-" after the bridge rectifier from the mains. Basically, you create some sort of grounding between the primary and the secondary of the transformer. I don't know the capacitance value (I took one capacitor from a dead charger and put it to one that did not have this and had the problem with the phone. I did not check the label, but I am sure there are some schematics around. Maybe you can take one from a dead PC psu.).
PS: I have done this a few minutes ago, while trying to change a dead charger with another one (which I had it as junk) and it works.
Lately I've been having trouble using the touchscreen while my phone is charging. Touches are not recognized, extra touches are inputted, touches are recognized in the wrong place...etc
I'm totally stock, not rooted. Thoughts? Thank you!

This is an old problem with the RAZR. I think it's an earthing problem or the lack of one. Touch screen goes a little awol...
Usually, using the stock charger gets rid of this problem!
Yes, check the charger. I had a device that plugged into the wall and simulated a car charging port and could use a car charger on the wall. It made my touch screen go haywire. Since the basic jest of a capacitive touch screen is using minute static charges in your fingers (or what ever other body part...) then it makes sense that if the rectifying circuit in the wall charger is substandard, excess RF emissions could jack up the screen.
Also, stay away from Van de Graff generators, they tend to cause the screen to be crazy as well. I know, hard to believe, but trust me.

I had the same problem with my old Milestone. Used stock charger. If I charge RAZR with Milestone's charger, I get the problem less often.

Same Issue
I was going nuts thinking I was touching it incorrectly then realized it could be some issue with charging it. I am using the stock charger but still seems to screw up if plugged in. Especially when I am trying to use swype. It stopped doing it once I unplugged the damned thing.
Me too...specially while typing a message....
I have this problem because I bought a real cheap charger that would do mulitple ports, but since I charge it at night I dont care. If I use the stock charger or the one from my OG droid it works just fine. Its something to do with the charger and being crap
I had the same problem with a LG charger, that came with a non-touchscreen phone.
When I use the stock charger, I have no problems.

Same here. I had a SE x10i and MB300 both had the same problem. Realized later that the problem occurred only when I using a particular power point.
Sorry for gravedigging but this is happening to me too and I only use the stock charger :S
No solutions yet for this issue?
My stock charger does this, but fortunately I have another from HTC which works.
This is a common Motorola problem, touchscreen input is more or less distorted during charging. I had this with Milestone and it also happens to RAZR, regardless of whether the phone is attached to USB cable, original charger, a 3rd party charger, original car charger or a 3rd party car charger.
I've had this problem too, occasionally. I just reboot my phone each time it happens, and that seems to fix it for a while. It doesn't happen often enough or long enough for me to really worry about it.

Hi. I have the same problem and I got to say that this is the second phone that I experienced the problem with. First it was a iGlo A101 and now it's a Allview P5 Mini. I tried them with 2-3 different cables and none worked (it worked only charging in the car (the first phone) and charging it through the laptop (connecting the phone to the laptop)).
With the iGlo, I asked the warranty guys about this problem and they said that is a common problem for capacitive touchscreens because it works based on electrical impulses and therfore it's sensitive to electricity. They also said that the reasons must be the power source beeing with parasites or the cable. They suggested changing the cable with a thicker one (a Blackberry or Samsung cable).
I didn't get to do that because I chose to sell that phone and that's what I did. And now after buying this new one I have the same problem. This time I'm going to try more cables before deciding to sell it. I'll update this.
I've had a similar issue, both with Droid 2, Droid X2, and Razr Maxx. The only thing I can say for certain is that I saw it started with rooting the phones. Only had it happen with motorola, and never had anything get better, regardless of what wall charger. I read on one forum a common problem was a loose charger, but have never found any validation, or it's just a common issue with the Blur being rooted. However, if it's the price to pay for rooting, I'll take it happily. But cruising google, I've never found a solution.

The only thing to do is use the stock charger, I have the same problem too when using another cheap charger. It seems to be a Hardware issue, not a software, so there isn't a way to make it works fine!

This happened to me having the Usb Debugging turn it on, disabling it it stops this problem to me
I have had this problem too. Using the stock charger took care of it for me. It's frustrating. It's not so great for Temple Run 2 either! lol
Having same problem ...with stock charger!!!
n its really erratic behavior sometimes
I have a Zopo C2 platinum and encountered the same problem. Solution : disabled USB DEBUGGING. And voila, everything OK !
Hi. I'm experiencing very strange behaviour when charging.
The digitizer responses very odd to my touches, sometimes in an other place than I tapped, sometimes with a fuzzy trail.
I'm using the charger that came with my phone.
Right now I can't reproduce the fuzzy trails and out of range taps. But when I can I'll attach them.

I've never seen the "fuzzy trails", but I can confirm that the phone acts as if it's getting touched in weird places while plugged into a charger.
I thought I read that this occurs with non-standard chargers, but I guess it happens with the stock charger as well?
It can be very annoying when trying to text/type, I'll actually unplug my phone to text/type, then I'll plug it back into the charger.
p.s. - we're not the only ones who run into this problem. I think it happens to everyone.
Can confirm this^^^^...usually happens when I'm using one of the many chargers laying around the house (non Motorola)

Yes, there are posts on other sites with the same problem and it is traced down to not using the Verizon charger that came with the phone.

No i have no debug and if charge with USB of my notebook not have problem, the problem is with original charger i have tested simultaneous 10 touch in screen with a finger!probably the voltage is not stabilized.
Sorry, I know this is an older thread, but.. Yes yes yes, I have this behavior too while charging. I thought my digitizer was packing up after only two months. But now that you say it's while charging.. So true.
I had this same issue on my Milestone A853, but it wasn't while charging - it was all the time. It gradually just got worse until I had to send it in for repairs.
But if the Razr is doing this only while charging, I might manage to cope with it. Although it does not always do this while charging.

I only get this with some chargers. With the charger I got with the phone, it does not happen.
So I have had this I9100 for about a year. Flashed with CM10.1 long ago and been reflashing new nightlies when i see stuff on the github log that address bugs I want fixed. Anyway the other night I put my phone charging, I didnt flash anything that night just a normal day. Next morning phone is dead. Wont charge, wont boot, no recovery no download mode, PC wont detect anything when I connect via USB. Odd thing is that now when the battery is inside the phone it starts heating up like crazy on both sides of the back camera/sim card slot, I guess where the CPU is.
So I searched for people with dead and bricked S2 and didn't find anyone with this problem, then I searched for people with other phones and again no one with this problem.
So I was wondering if USB jig would be able to help me, or JTAG, or if its just the usb board that died since it was while charging and it gives off no signal via USB to a computer and if I changed that it would come back to life.
What do you guys think? Was it the main board or is it just a fried USB board and the phone can't regulate power without it?
Sounds like the USB board, but you never know until someone 'qualified' has a look at it. We've had a lot of similar problems on here over the past two weeks (this week in particular I've seen maybe 5-6).
Doubt a jig or JTAG would be any good given it isn't a firmware type issue by the sound of it.
I guess I'll order a usb board a replace it. If it doesnt work its not expensive anyway. About $10.
I was wondering if there have been a lot of people lately with this problem could it have been one of the nightlies that screwed up power management and fried the board?

Yep if you can get a cheap one 2nd hand it's no great loss if it doesn't work & you end up needing to replace the MB as well. If you need them, I attached the SGS2 service manuals to a post of mine a day or two ago (click on my name & have a look through my posts over the past few days) if you need/want them.
That's an interesting theory. Not being a dev, I'm not up to spec on whether anything at, say, kernel level could cause something like that to happen (In the 18 months I've been here, I've never seen a kernel/firmware pinned down as the cause of something like this), but you wouldn't say it's impossible.

Did you try the ole toothbrush trick?? Get an old toothbrush and put it into the usb port an go mad. Sometimes a film can be on the terminals of the usb port, which gives you a bad connection.

With the multimeter check is there a voltage coming from the battery. The battery by itself!. Next leave the battery out from your phone and plug in your charger (which is connected to the wall). Put the multimeter across the appropriate terminals of the phone and measure the voltage if any.
Report any voltages values you have

The battery gives off a steady 4.
The phone connected to the wall without battery gives off 1.3 when first connected or the battery removed and then very slowly starts dropping to 0 going slower as it drops. By the appropriate terminals i imagine you mean the ones that connect to the battery wherethe battery has the + and - symbols.

That USB port is working, battery is fine. Next the screen might be dead. First check to see if the backlight is working. Turn on your phone as you would normally shine a light onto the screen and see if you can see anything. Use a flashlight or something with a high focused beam

So batery and usb charging normal. No screen problems, and heating cpu while off. Most likely main board fried? I'm gonna get some resistors to make a jig and try that anyway. Do you guys thinks 330k ohm will work too? I know its 300k ohm buthave some resistors around that add up to 330 and i wouldnt need to go buy more tomorrow.

Yeah...that CPU heating is a worry.....it's obviously being forced to do something that it wasn't intended to do....and it doesn't like it.....
And with regards to changing the impedance of the jig....probably not advisable. ....micro electronics is very sensitive to resistance and voltage. ...what you're doing with the jig is essentially bridging two connectors. ...
Impedance too low....too much current/voltage passes.....things might begin to get hot (best case)
Impedance too high.....too little current/voltage passes.....no effect.....

I was asking this because it could be some sort of loop in some process it does when detecting a batery.

Well, I'm sure I remember reading *somewhere* that Android phones have a secondary/simplified/low level kernel that runs even when the phone is switched off......apparently that was how some phone on verizon was hacked or something.......
Whether that's true or not....I don't know....
If it is....it could fit in with what you're suggesting....
