When my Mytouch 3g Slide is plugged in the touch screen goes crazy. It isn't accurate and starts clicking everything. Could it be my charger? 5.2DC - 500mA

I'm guessing that it is because of something along the lines of the electricity from the charger shorting to the touch screen, and since the touch screen works by using the electrical signals in your fingers, the electricity is screwing with the digitizer. I doubt its a charger issue, probably something within the phone. You could try using another charger. Does it happen when you plug your USB cable in?

Really? Anyone that does any troubleshooting knows that if problem is unknown that one must start eliminating possible problems.
@shefsalad: If the phone is fully functional before plugging it in, then the charger must be the issue. Now since the charger is two piece, it must be the cord or the charging unit. You had it right with asking to plug it into a computer. If it works fine plugged into a computer, the cable is fine and its the charging unit. If you'd like to further put suspicions to rest, see if you can borrow another persons charging unit or see if tmobile can lend you one for a minute.

Then there's a good chance it's the charging unit, like the other guy said, try to get another one, maybe a warranty replacement from tmobile. It would also be good to try a different unit as well as a different cable entirely, as the problem could still be with the usb cable. We want to narrow it down as much as possible.
@guitarist5122, no need to be so hostile, I was simply projecting a theory. Somehow, electricity is flowing over to the digitizer with the phone plugged into ac power. This is why I asked him if it happened with just the usb cable plugged into his computer. If it didn't, then its possible that either the charging unit is defective, giving the device too much electricity, which is resulting in it discharging in the digitizer or elsewhere, or it could also be that the wiring within the phone is slightly messed up, so that the small voltage of usb doesn't affect it, but full AC power overloads it. Now all he needs to do is try using a different AC unit to determine the problem. However, the problem could still lie in the usb cable, the problem could just not be emerging until full AC power is fed through it, so it would be ideal for him to try an entirely different charger, with a different unit and a different usb cable. This would eliminate all possible problems. So, I think my troubleshooting skills are just fine, thanks.

No hostility. Just pointing out that i see advice coming from little knowledge disguised as solid advice. Nothing wrong with advising people with what knowledge we do have, but mention that the advice is based on little knowledge and may be inaccurate.
I must point out the flawed advice. It simply cant be the cable since the cable just transfers electricity. In this instance, it could only be the cable if it had a bad connector (the standard A or micro B) like maybe a bad ground. If that was the case the problem would carry over to the pc.
Also, it has nothing to do with AC simply because the phone does not recieve AC, but rather DC. The charger converts AC to DC. DC is the same current coming from the laptop as well. If i actually think about it, i dont know a charger that supplys AC to a device (especially a chargable one).
I experienced this when I tried to plug my Motorola Milestone into my Dad's Blackberry 9700 charger. It charges just fine, but the screen goes wacky when I touch it. Other chargers such as the one from Motorola, or my Nexus One charger, did not have this problem. So it appeared to be some sort of odd grounding issue.
I also have this issue happening, but only with the cheap aftermarket charger. It also does it to my girl's motorola Cliq. It's simply the charger, get a new one if it bugs you, or unplug it when you want to use it.
Thanks to everyone for your input and advice. I was worried that this might cause my phone to explode or something.

Have the same problem with Desire HD
I'm using HTC charger and cable, it also happened when connecting to pc so I'm suspecting the cable.
I'll try a different charger and cable then I'll try the original charger with the new cable. The problem is that this issue is happening sporadically so it will be difficult to test.
Definitely the charger despite being the one that came with the phone
same problem.
I bought a local manufactured phone. And when i plugged in as for the first charge it went crazy when trying to use the phone. But it does even when USB is plugged in and not switched on.v but works fine when cable not plugged in. And when i tried my brothers Samsung Galaxy Nexus charger it worked like a charm with no problem. It's just matter of hours(2/3hrs) after i bought it.

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.

if you turn off the tab and then plug it in, does the battery screen come on and does the device charge?

My guess - faulty resistors in the charger or one of the wires in the cable is dead.
The Tab expects to see USB D+ and D- shorted together and floating at 1.2 volts, set by a resistor divider in the charger.
Does the cable work fine for USB data transfer?
I think the user has possibly used the wrong wording. If he's seeing the MTP mode come on that means that he's just got it plugged into a USB port on a machine whilst the tablet is on (whilst using the "charger" cable).
Simple answer if that's the case. The tab doesn't charge that way as there isn't enough power coming through the port to keep the tab on and charge. If you however switch off the tab, you should find it charges from the USB port
If not, let us know.
Actually the tab is going into MTP mode while plugged into the outlet, using the supplied Samsung power adapter and supplied 30 pin cable.
I think i need to call Samsung for replacement... although after really thinking about what I just typed I think might be simpler to just buy a new cable online.
Or is it the actual power adapter that's faulty....
Well that is quite odd then. Does the tab charge if you switch it off and then plug it into the outlet / pc?

No, his wording was explicit enough to indicate that the tab is falsely detecting the factory charger as a USB host. This will happen with iPad/iPod/iPhone chargers, and would happen with the factory charger if the cable were faulty (D+ or D- open) or if the charger were faulty.
Again, to the OP: Does the cable work for syncing to a PC to transfer data? If it doesn't work at all, that's a sign that D+ or D- of the cable is open.
Meh, some people use words such as charger and cable interchangeably in terms of their truer intended meanings at times.
I was simply trying to cover that base.
Not sure if the cable works for data ....as I do everything over the air. The cable was giving me troubles at the tab end, (loose connection) but lately has been working OK.
I also haven't been charging and using at the same time lately either. I really needto contact Samsung and talk to them about a warranty replacement, but I have a feeling I'd be better off just buying a new one off Amazon or the like....

I have the same issue. Check that with different cables. So cable and charger is not the reason
If you're running a ROM with Pershoot's kernel, you can "Enable Charge From ANY USB" (see link in my signature). If you're running something else, you can make yourself a "DIY Universal Charging Inline Cable" that will trick the Tab into charging off anything (again, see the link in my signature).
But before you go out spending money (even if it's just a little bit of $$$) you should see if the cable works for data transfer between your computer and the tab.
If the cable works, then the "DIY Universal Charging Inline Cable" will keep you going until Samsung sends you a replacement charger.
I had this problem and didn't know what was wrong for a while. It turned out the the charger wasn't plugged in all the way in the outlet. I guess it wasn't getting all the juice it needed.
Am suddenly getting this problem tonight also it sometimes turns my tablet off but won't let me turn it on till I pull the charger out.I've also noticed that if I plug it in when the tab is off the battery sometimes comes up saying it's charging
just plugged the usb lead in to 2 laptops and they both show a usb error
I started having the same problem 2 days ago. All of a sudden i plugged in the wall charger and it went into MTP mode. It will charge if turned off but I've noticed it takes a much longer time to charge. From 3% it took almost 24 hrs to completly charge. Thinking that I'll have to buy a new wall charger.
Please help
Another one about charging...
My 10.1 P7510 takes tooooo long to charge, even beeing off. If I connect it to my notebook data transfer is correct but battery keeps draining, or at least not charging. If I turn it off (either connected to PC or charger) the charging icon appears correctly. I must say that cable (and charger) are not the original ones
Is it a problem of the Tab, or cable, and/or charger ?
I think the charger did not have enough current to charge the tab while still using it. The stock charger should be rated at 5V 2A. I tried another charger with only 1A and it still worked. Anything lower than 1A will end up showing that MTP mode.

I've got the same problem myself except I had to clean the charger clean of marinade sauce (it's a long story, don't ask!) and I took the device back to my local Vodafone store (I got it on a Mobile Broadband contract) as I thought it was faulty. They claimed the device was working fine although they used their own cable and not mine. They also claimed that if it was the cable, I should be easily able to buy one.
I tried buying one in every store I could think of, including the phone repair shops and they didn't sell them at all!
It's just a shame that a tablet like this which could have been a great tablet is crippled not only with no MicroSD slot, but also using a crappy proprietary socket whereas all the other Tabs have a MicroSD slot/uses a Micro USB port.
(I've already ordered a replacement cable from Amazon UK in any case for a reasonable price)
mtp-connected and media scanner running
I bought. My Tab 8.9 last November, only started having this problem since last night. There is red cross and mtp-connected,also,"media scanner running". I am using original cable and adapter that come with the Tab. Has anyone here found a solution?
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.

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.

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.

it's not a SGS2 only issue, it happens to all the other phones i've owned before
The reason I ask is because I have multiple USB charging cords laying around the house, and I actually wanted to take 1 to work. And since at work I need a long cable, I brought to my job.
The problem is that the cable I brought to my job is not an official Samsung cord, and it would plug into the bottom port, but it wouldn't charge. So then I went to another cord and apparently that one won't even plug into the bottom. The ironic part is that all of these cords would plug into my old Samsung Epic 4g Touch and worked fine with it. But now I've come to presume that not all chords are the same.
My question is has anybody else encountered the same problem? Or do I have a faulty bottom port? Yes I know I'm probably sounding paranoid, but it would be nice to know if this is an isolated incident. Thanks everyone.

I've plugged it in to many different cables, all work just fine.
I have an HTC one that gave me problems (difficult to physically plug in; once it was in charging was fine with the Note 2 adapter). So yes, I have noticed that. I assumed it relates to the changes (?) Samsung made in the port to allow for other connectors like docking and MHL, etc. (at least I think I read something about that). That same HTC cord has worked with every other phone I've ever used, including the Note 1. But most of my cords have no issues with the Note 2, so I'm chalking it up to tight manufacturing tolerances as companies try to cram more stuff into a small port.
I have been using an htc one with my pc. Im surprised it even charges my phone at all since most car chargers wont and we all know that charging by pc is really slow. I mostly use it for transfering files though. Maybe you do have a faulty one? Another thing you ahve to realize is the orig charger is a 2 amp and most other ones are 1 amp.
I just purchased this unit. is it normal that the Stock Cable is Hard to Plug on the Charging Port of the Phone..

I noticed this as well. hopefully if something gets broken its more likely to be the connector on the cable than the charging port. I have tried a few other cables as well and all are pretty difficult to insert.
Well the way I see it would you rather have it flop around and be loose, or have a night tight fit?
On a more serious note I had the same issue when I first recieved my F400S. After a week or so it got better, you can always try an older micro usb cable thats more broken in to avoid this issue.
when i first got the phone it was like what you've desribed. but after a while, it wasn't an issue anymore, i guess its a good sign that the phone is brand spanking new.

Hi,
I tilt the usb-connector up (just a bit) while plugging it in.

It requires a downward angle tilting towards the device to insert.

Only way to get it in is by tilting the cable downward. Tried few cables, they are all doing the same thing. Exchange perhaps?

Tilting the cable to plug in seems to be the norm on pretty much every G3. I doubt exchanging it will help.
Once you've done it for a while, it should become pretty easy to do.
Tilting the cable and just dealing with it are fine, but what happens when you stay finding usb cables that don't want to charge your G3 properly? I have one (very nice) 10ft cable and my phone plays a game of connecting and disconnecting while trying to charge with this cord. This courts does not give me the same problems on other devices. However the G3 charges just fine on all my other cables. Not using this cable is an obvious answer but i worry that the problem could get worse and what if I start having problems with other chargers?
For now, the solution is to tilt the cord slightly downward (or upward, depending on your perspective) as the port is just sliiiiightly more flush with the opening. My advice is to get used to doing this. A broken charger port is really a PITA, so taking an extra 2 seconds to plug it in is the prudent choice. My dad gave me a lot of good advice when I was growing up, and one of the gems turns out to be "don't force things."
As mentioned, once we get some wireless charging back covers on a more accessible basis, we'll all just use wireless charging and never plug in again. Except in the car.
The cable from my old GS4 plugs in very very easily. I haven't tried charging with it tho. I use it mainly for usb mtp.
Posted from my LG-D850
Difficult at first. It did get better for me though. I too thought i had damaged it or that it had shipped that way. And I also thought I was just breaking it more each time I charged and contemplated exchanging LOL. Make sure cord is facing the right way first (im still trying to put it in upside down sometimes), then you do have to tilt it down a bit to get in initially and then it tilts slightly up before fully inserting. It was very diificult to do the first couple days. Day 5 and its way easy. Hope this has helped and put your mind at ease This is my first Android phone and i'm luvin it!
the past new phones i had. was always hard at first to plug it in.
just gotta lube it up
Any new updates on this? I guess tilting the cable a bit is working, but will it ever get to the point it will go straight in? It really appears that this is not a defect but a LG design for the port.

I agree with what was previously stated, after a week with phone, I've become used to putting the cable in. I'm pleased with the tight fit as I've had devices where it feels loose and unsecured.
