My hox is on stock jb 4.1 and while charging the screen doesn't works properly.there is no problem when unplugged.could anyone help me on this problem.

Some HOX's have this problem. Its more common than people think, just not many use it whilst charging.
Its not native to the HOX either, HD2's, Titans, Xperia's etc have all had issues reported about this sort of problem.
Quick question: Are you using:
Original Charger?
Original Cable?

Yeah, most people when charging either go to sleep or charge it whilst doing something else such as a Bath Etc.
Hense why most don't notice these issues.
Quick question, do you know if I am right in thinking its do with how the charger grounds(earths) the phone?
Its not due to grounding, the charger has no ground wire. The phone is double isolated (ip44) I think it has more to do with the fact that the phone is more busy with concentrating on the charging and controlling that process. Hence why the digitizer might get a bit less voltage and doesn't respond as good as without the charger.
This is totally my own logical explanation, not saying its 100% correct but i can't think of another reason atm.....

Pretty sure there is more than one digitizer which would explain why some have issues and some don't.

For me this happens on HD2, Sensation, OneX, only on one particular wall socket regardless of whether phone is being charged directly via HTC charger or from usb port of laptop. as long as laptop charger or htc charger is connected to that wall socket touchscreen on all above phones goes crazy.

Hi all,
From the first day i have my device, while it is connected to charger, although i just use my one finger it feels like multitouch, so it zoom in or out screen. After disconnected charger, i firstly lock then unlock screen and after that i can use my device normally. It sometimes cause screen vibration with no multitouch supported softwares. But it actually can't let me use any browser while charging...
I though it was because of setcpu profile but it only has 1.2 ghz and i already have this clock speed between some battery levels. What problem should be with my device?

I think that the htc devices have a earth(? is it called this way in english? The negative pole of a battery?) problem.
They are the only devices who have a metallic battery cover which is connectet to the device itself. (Lock for the small pins)
I also have your effect sometimes, but when i touch with one hand the battery cover it's a bit better.
on my old hd2 it was the same, but even more worse...
Seems like a generell htc failure...
It is fairly common for devices to have problems with their touchscreens while charging. Not just HTC; I have the same problem with my Nook Color, and I had the same problem with my Motorola Cliq.
The most common theory I have heard is because the charger does not charge at a consistent rate, which messes up the capacitance that our touchscreens use. This is especially true with aftermarket chargers, but can sometimes even happen with the original ones.
The best thing to do is to try not to use your phone while charging, or spend the extra money and get only original (OEM) chargers.

You have it right. I think the full word you're thinking of is: ground
Though I would think and hope all devices have one. Of course having a capacitive screen there are more complicated issues to deal with since you still need to maintain a certain amount of static charge on the screen. Basically your body is used as the ground on a capacitive screen. Obviously the ground on some phones is interfering with that.
I was aexperiencing a similar problem. Whenever i would use the Mugen battery and the second i closed the back cover, the phone would switch off. if i let it a little open it would play normally. With the standard battery although it didnt behave as such. Weeeeeeirrrrddddd

That was my solution. I charge my phone while I sleep, so I don't have to worry about it. I also have a charger at work, so I can "top up" the battery during the day, if I need to.
i found out touching the metallic part of the phone sometime cured the problem
While charging, i opened multitouch app and confirmed red and blue colors change to yellow and green sometimes...

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

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?

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

Its your charger, turn on show touches in developer options and see where it is registering your finger when on charge, then try again when charging from your computer.
Me too experienced this. Are you on stock or custom rom?
I am on custom rom! Now in charmeleon i dont have any issue.
I'm experiencing this on my HOX as well. The unlock ring becomes nigh on impossible to drag to the center to unlock & get to the home screen. Completely stock & on 1.29.401.11
I also have this problem too, using stock unbranded phone on latest software. When plugged in with official charger its very difficult to unlock and slows screen response considerably.

this has been mentioned before, i get this issue sometimes, some people say its charger, but it can't be, seeing as both my chargers do this, and my desire hd doesn't do that on either charger, so by process of elimination it must be the phone at fault, seeing as it only happens when on charge, and not always on charge, i suspect a software bug somewhere
report it to htc though, then we might get a fix sometime.. i already have btw
Does it do the same when charging via your USB port on your pc?

I wouldn't necessarily say that. My friend has a charger that messes up my Infuse's touch screen, but it has no issue on his phone. Certain phones can act weird with certain chargers. I've never really understood exactly what the issue is, but the HOX seems to be pretty picky. What worries me is the fact that it seems like there are a number of people with issues with the stock charger. It makes me wonder if the issue is a build issue with the phone, perhaps in the connector, that's making it picky or causing the problem all together. We should probably start gathering information about phones that have trouble with certain chargers and what version of the phone they are and see if there is a common trend.

Sometimes after i do manage to unlock the screen while on charge, the phone will immediately open the 'Phone' app. I thought it may just be because I dragged the ring too close to the 'phone' quick launch icon but definitely not the case.
Has anyone else experienced anything like this?

I had this too from day one and thought I had a faulty handset. I noticed somebody mention the charger and at the time I was using my (not too old) Sensation XE charger. I switched to the charger supplied with my HOX and haven't had the problem since. Still seems strange why this occurred because using the cable from the Sensation to connect to my PC it was never unresponsive, only when it was plugged into the wall socket.

The reason you don't see the problem when connected to your pc is because most computers have good quality,regulated supplies to provide the 5V on their USB ports. The reason some wall chargers, even the official One X type in cases, are affected is because they are switch mode power supplies which convert 110/230V AC to 5V DC using high frequency pulses, if those aren't filtered properly they interfere with the touch screen. That's why I suggested testing by charging over USB earlier.

brilliant point, it so happens that im currently living in an old house, with a crappy power supply, even my speakers were affected before. i don't have this problem whilst charging the phone at work (albeit with a different charger)
I think ill try plugging into different power ports around the house etc and experiment a bit... never thought it could be the house, although again the dhd isn't affected, so something must still be missing/not right on the one x for it to display this symptom.
Hello guys, my problem is that on every rom I tested sometimes (there's no rule for it) my touchscreen stops working, it's looking like I was scrolling very slowly when I'm not. Solution is to lock screen and unlock again, so this isn't very important to fix but I just wanna know if I can do something with it or its for example low polish electricity sorry for my english.

Hello there folks. I've had my Desire Z for 2 years and it always worked great, it is rooted with S-OFF, HBOOT and all, I was running Andromadus Mimicry 1.5.0 ROM. It was working flawlessly as usual, but yesterday I picked it up and it was turned off, I figured it needed a charge so I connected it to the charger, but to my surprise I didn't get the usual orange led, as a matter of fact I got nothing. I waited a few minutes but still nothing. I tried to connect it to the PC but again, nothing. So far I tried different cables, different batteries, chargers, tried the car charger, but nothing seems to work. I tried using ADB to run a Fastboot command but that also didn't work, it hangs forever on <waiting for device>, and ADB doesn't detect it. It really seems absolutely dead. It doesn't show any sign of life, no light, no vibration, NOTHING. Has anyone ever seen something similar? What can be done to resurrect it? I didn't do anything different, it was all of the sudden. I appreciate any help, thank you!

Hey, thanks for the reply! While researching what could be the problem I came across this eMMC issue, I was hoping that wouldn't be the case, but unless someone else sheds a new light on the subject I guess that's probably it. I even looked for a new eMMC chip or Vision mainboard, but couldn't find them anywhere. I guess with the price of a brand new Desire Z at U$90 - 120 nowadays it wouldn't be worth it anyway, I might as well just buy another one, as a matter of fact I probably will, as I love this model so much, but I really wanted to save the one I already have, that way I would have a spare.
You can buy a new Desire Z and keep the old one as a restore device who knows maybe some day you gonna need a touchscreen or a LCD panel or both?
Just keep it

Yeah, I thought about that too, I'll probably need it sooner or later, I had to exchange the led flash once. Who knows, maybe the eMMC could be fixed with JTAG, but that RIFFBox is so expensive. If it weren't I would certainly get one as it's useful for all kinds of phones. Hey, thanks for the reply again, I really appreciate the input. I hope the thread goes on and people keep giving new ideas.
Chances are it isn't an emmc issue, as the emmc issue just stops the emmc from being written to, so the phone will show some signs of life.
It will be some sort of hardware issue though, seeing as it's not doing anything at all.

Thank you very much for the info Nipqer. Is there a way I can tell what kind of hardware issue happened? It really doesn't show any signs of life, no lights, no vibration, no orange led while charging, nothing. Aside from that the phone looks brand new as it has always been well taken care of. Is there something I can do or try out? Thank you.
Did you try a new battery? Or an external charger? It is possible battery is fried or USB port is dead, a new battery and external charger could help figure that out.
Also you can try taking out the battery, plug into PC via USB while holding down both volume buttons, phone should vibrate a bunch

Yup, I got 2 extra batteries besides the stock one that came with it, one of them is a Mugen Power Battey and the other is another original just the same as the stock, tried many different chargers, 4 other wall chargers, different cables, car charger, etc. Doesn't seem to be the problem. Tried to do as you said about taking the battery out and plugging into the PC via USB, still nothing, not even holding both volume buttons down or any other buttons... Hell, I even tried holding ALL of them. Still no deal.
Sorry to say but my guess is logicboard is shot, good news is a new dz/g2 is cheap nowadays
