I found a kernel in ATT Note that removes ghost touches, so that might be just the thing that slows it down.
Mine gets slow too..I'm got beastmod5 with darkside kernel ..
It lags crazy when using adownloader

What was the point of this thread?
And yes I am aware of the issue u speak of being as it is widely known that the phone is less responsive to touch while on the charger.
I found using crappy chargers will really show this issue.
With one the screen is unusable.
It sounds like it converts over to mains power to allow the batter to charge, however the battery is sucking the majority of the power from the line so there is not enough to fully power the unit...

That the developers can contact him, or they can just take off the piece oof code, and there, we have good working touchscreen, it will also be ffaster and more responsive always.

Because the kernel makers add the water proof touchscreen optimizer, something like that, that makes it able to use while water is in your screen. But if you disable it, it would be a lot faster.
these strange issues are usually caused by cheapo chargers
it doesn't do this when you charge via a computer USB or wall using the original stuff
a decent build quality of china made wall / USB chargers will also work fine.
it all comes down to the quality of the power regulator in the charger

Well, it happens to me in all ports, in all USB cables.
Happens to my GS2 on *any* custom ROM with the stock charging pieces. The stock firmware never has touch-lag when charging - ever. YMMV.
This is wht I'm trying to say
For those a bit confused as to what 'Ghost thouch' is, and why it is removed:
Samsung added a bit of code to the touchscreen driver on the non-intl version of the note to detect 'ghost' touch input events, similar to the raindrop detection on the original Motorola Atrix (and others). While a nice idea on paper, this had un-intended consequences when trying to perform multi-touch input that continues longer than around 5 seconds; such as playing some games. It is now disabled in this kernel.
Edit: There also seems to be a pleasant side effect that I hadn't noticed... keyboard input is improved. Makes sense I suppose, since now there isn't this constant check for false touches slowing things down. Let me know if you see this on your device.

I have this issue too no matter which rom is being used or which charger im using. If there is a way for me to disable that "water drop" thing im sure many would take kindly to that.
Its a samsung thing. I've had several samsung phones and the touch screens always goes wacky while charging

I know this happens on alot of devices. When u plug it in the current from charging interferes with input sensitivity. But it is VERY well pronounced on this phone. This the only thing that's bugging me about this awesome phone.
I just want to make sure I'm not the only one having major difficulties while plugged in. Post your results here please. Thanks

Yeah its the voltage or amperage whatever on the wall charger. Try and find one with a smaller output
wait so the adapter bundled with the Epic Touch sends more amperage than the thing can handle? and to the point of interfering with button sensitivity?
I do notice it a little bit, but I Have had it plugged in for over an hour now, it happend to me about once or twice. nothing too bad.
I used my tabs charger not thinking...no issues

Its not that the stock one is "the wrong" charger. Its that the outlet charger is meant for rapid charges so it puts out alot more than say a usb port. Thats why usb takes alot longer to charge and the wall charger can do it in a couple hours.
Sounds kind of odd... I have used 5 different chargers with the normal epic and never had any kind of issue as the phone has it's own internal current regulation. I had put a 3A charger (WAY overkill) on my epic with no issue. If this is causing your phone issues, I would give it a few days, see if others have the problem and if not, exchange it ASAP.
See I always had that issue with my evo and hero. If I used a 3amp charger the input was whack as hell but if I used my 1.5amp it was perfect. Wonder if its an outlet ground issue or something else.

Do we know what the chargeing level is on the epic touch? I know for the epic it was 600mA if D+ and D- were shorted and 380mA on data USB if the data pins were not shorted.
it has happened with my last few devices. I will say this thing charges pretty quickly..but yes when it is charging my phone is a pain to use.
As far a charging ratings...well..I aint that smart. lol

I noticed this too, sadly I didn't say anything cause I thought it was me hitting a button or something by accident
I have had this with all my htc and android devices. It does it at my house only. When Im at my parents charging it does not interfere. Evo was real bad, epic has been alot better. I have noticed that once it is charged the issue is usually somewhat resolved. It would be awesome if someone found a fix to this. Though im pretty sure it is my old house or the radio towers 3 streets down that I can hear on my landline.
maybe I'm in the minority but I consider this a big issue. I've never experienced anything of the sort with my Epic and, like a previous poster, I've used all sorts of cables and chargers. will have to wait for some more feedback from new users on it, though.
what does "input sensitivity" mean?

its not a huge issue for me...but yes, i think it can be fixed via software update. happened to the Evo when it first launched
Im not noticing anything like that... I guess we will see but so far so good
I am not getting anything like this either.
What exactly are you guys seeing? I'm charging mine now and haven't noticed anything unusual.
Sounds like it might just be "dirty" electricity basically if someone even has it only happen at once location but not another. Not much you can do about that but test it and put filters on... both things cost money. Maybe this phone is more sensative to it than others.
Perhaps we should start a sticky listing any bugs found instead of having a thread for each one discovered?
The phone is absolutely stunning and a definite winner. It's really sad that it seems that I may have received the lemon in the bunch. Hopefully this is an isolated issue but my phone starts having serious technical problems when attached to a charger. Screen unlock is hard to orchestrate, applications and contact lists and settings menu's open on their own and even attempt to execute their own commands. The phone is fluid and beautiful until u want to charge it and use it at the same time. I think I got a lemon. I've already processed an exchange with Wirefly and they were extremely responsive and immediate in processing my request. I tried doing a factory reset to no effect. If there are any other trouble shooting suggestions I would appreciate it. It is really a shame that this phone may be a lemon. I searched and read about similar issues with the previous epic when using an aftermarket charger. Everything came in the box with the phone here, oem. It is possible the charger may be bad but I might as well exchange all of it just in case. Could be a slight short or something that bad.

Did you have Kies air running in the background?
No I've closed out the apps and it's still an issue, I've also tried a factory reset.
Known issue, common to a lot of phones. Can be fixed with software. Doesn't seem to happen over USB charging and it seems to happen much less severe the closer to 100% you are.
Not a lemon at all....it mildly annoys me.
Thank you for that link to similar issues with international GSII users. I am going to go and test it out on various outlets throughout the house. I will also try using various settings with SGS touchscreen booster from the app market. If anyone else experiences this please let me know. Honestly, after my exchange if this is an issue with the new phone as well I would still probably keep it. I should also test whether this is an issue during regular USB charging. I'll be back with the results.

Yeah, some outlets/power systems are likely worse than others. Stick with USb charging if you don't need it charged rapidly. I've had no problems with that so far.
Problem consistent on four separate outlets at all different settings using screen booster app. USB charging does not have this problem though. I may just have a sensitive phone. It would be nice to confirm with another epic 4g touch owner though before I carry out the exchange.
My friend's E4GT had a picture in the gallery of a Best Buy employee flipping off the camera and to make matters worse, the device will not charge...
The phone is downright sick though, a long term keeper. Featherlight, it feels surreal when you first receive it with how wide, long, light and thin it is, so surreal it feels like a fake phone. So thin and long the first thing I thought was this thing looks like it could snap in half. But my first Evo came with a bad pixel too so I guess with this one I'll try again. Honestly, I'm keeping the next one no matter what.

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?
Sent from my HTC Vision using xda premium
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.

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?

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.

better charger yes

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.

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
I've come up with a small patch that changes the fast charging behavior in FastCharge kernels to not disable USB, but still be able to fast-charge the battery. Good if you want to USB tether, while still taking a charge. The old patch fakes out the FSA9480 (and friends) to pretend that there is a charger, not a peripheral, connected; the new patch simply jams the charge current GPIO high in fast charge mode, which has the same effect, but without killing off the actual USB connection.
I prototyped it on TinyKernel, and it seems to work (thanks to tiny4579 for helping me test, since my toolchain seems broken in a bizarre fashion). If you're a kernel developer, you'll want to cherry pick these two patches --
https://github.com/jwise/tinykernel-gnex/commit/5fed4d674e44129502b045b350594552c96acb79
https://github.com/jwise/tinykernel-gnex/commit/8e7e8b4bacfe1ef5d86c52f96232c76fc3d0a181
I don't have a direct way of measuring it, but it seems to be effective through an indirect measurement: staring at a Kill-A-Watt (which my laptop is plugged into), the power measurement jumps by about 3W when I plug in the phone without fast charge enabled, and by about 6W when I plug it in with fast charge enabled. The charge rate also seems commensurately faster.
If you use this patch, feel free to credit me as 'Joshua Wise <joshua at joshuawise dot com>'.
Enjoy!
edit: Please also cherry pick https://github.com/jwise/tinykernel-gnex/commit/8bc251d313001f1e2ba35523d62429c9c0cea12b, to fix an embarrassing bug where I failed to appropriately turn off the charge GPIO when the charger was disconnected.
Will this cause any damage? Something seems... iffy, here.
Great great work here. I am too cheap to donate to Verizon and buy OEM chargers from them so I use fast charge constantly. This is will, I'm sure, be a regular household product among custom kernels everywhere soon!

It shouldn't.
Both of these patches -- the original, and mine -- work by faking out some part of the system. The original patch worked by faking out the charger detect logic, jamming the USB controller's detection into believing that there was always a 'charger'-type device connected (not an MHL-type, or USB-type device).
This patch works by faking out the charger enable logic. The charger detect logic in the kernel set a series of flags that further and further down the pipe turned into enabling a GPIO that connected to the PMU, which actually was responsible for enforcing a charge rate. My patch tries to reduce the "collateral damage" by making the change as late as possible, only modifying the charge GPIO, rather than the entire detection logic (and, with it, the logic that turns on the USB OTG interface).
You are, of course, absolutely right to ask this; messing with charge code is always scary, and you should always be wary of changes to how the system's power management works. But, in this case, I think that the patch should be at least as safe as the original was.

You mention mhl, will this work with that as well to hopefully squeak a little more power if available out of a mhl adapter?

People have been doing this since windows mobile. It won't hurt your phone and will only hurt old USB ports that can't output 1000 mA or so.
Edit - should add that it won't hurt your phone as long as it sticks to the AC charge rate .

As the OP said there is a risk when messing with power management (the charging rates in particular). That is the potential negative. What I do like about this patch is that you can enable fast charge and keep USB mode. I didn't know it was possible on this device.
Also there is no a in kernel.
Oops, of course, an embarassing bug -- I didn't disable the fast charge GPIO when the charger was disconnected, which I think was resulting in excessive power draw at idle. (Luckily, it was fast to charge the phone back up again! )
Developers will also want to cherry pick:

And it should be very easy to compare this side-by-side with the previous fast charge text to show the only thing changed is what he modified to trick the phone, and not any of that power stuff.
I am curious with this patch if it will be able charge while using the GPS, with all radios enabled? Any thoughts?
So is this dead? It was a awesome idea because I myself use Fast-charge almost daily.

No it's not. My kernels have these patches integrated. In fact I was the original tester. Too bad this wasn't around when my GNex was a daily driver as it's quite nice and seems to burst the charging rate without sacrificing USB functions.
Are your kernels the only one with this patch Tiny?

Oh cool. I have been waiting for some sort of reply that it was finished or that he had some file to flash to enable it haha. Well, I am gonna try your kernal out tonight+tomorrow, thanks.
Yeah, I've been running it on my phone more or less full-time, and it's saved my ass many times over ...
I'm building my own gnex kernel and this is definitely getting included ... Many thanks Op :thumbup:
