Yesterday night I was playing with the phone before sleeping. It was charging not with the provided ac adapter, but with the usb-miniusb cable + an aiino usb-ac adapter. Well, the weird thing is that using google maps, the touch/multitouch control was completely f****d up. I mean, it was impossible to pinch-to-zoom, using the zoom buttons worked, but when I used only one finger to move around the map, instead of moving it was zooming randomly in&out without a reason. So I unplugged the cable and it was working perfectly...
It seems your 3rd party ac adaptor is not appropriately grounded so there is a small current on the touchscreen. Capacitive touchscreens recognize minimal changes in currents on the surface. That's why fingers, oranges, organic material work with it, but no stylus or other pens.
Hmm that's an interesting point, I didn't think about that. Do you think I should stop using that charger? Could it damage my device in some way?
I got it with my iPhone 3GS on a car charger too. But it didn't hurt the device at all.
I cannot guarantee this though...
I always used it with my iphone 3g too, and also used my iphone while it was charging...but I never had such an experience on iphone's multitouch...that's really strange!
I had the same issue with a generic ac micro usb charger I bought on ebay.
Since the phone was just newly released, there seemed to be a premium on the chargers described as being for the galaxy s so I went and bought a much cheaper micro usb charger compatible with motorola devices. I figured the contacts would all be the same and all micro usb chargers the same.
Wrong.
As soon as I plugged in that charger, the touch screen was borked. The display was fine but the touch response was shot. If I tap the application drawer in the home screen, it would register a click on some other random spot on the display. The phone was utterly useless while plugged into this charger.
To troubleshoot, I tried mixing it up between the original samsung charger and the generic, resetting etc, and it always came down to the charger. Crap with generic, prefect with original.
TL;DR - not all chargers compatible with samsung galaxy s, borked touch response from generic charger.
Perhaps it would be useful to change the title off this post and move to the accessories forum? Useful for people to add their feedback on generic chargers they've used.

Btw, the charger did charge the phone but I guessed having extra current run through the screen would damage the capacitive sensors.
Compared to the original samsung which has 4 contacts, the micro usb plug on the generic had an extra contact. I tried to open up the plug to see if I could do something about the extra contact but it broke and I the it out.
Shame I didn't think to make a video to share.

i bought my SGS on ebay and it didn't come with a charger.
the 3rd party charger i bought on ebay doesn't charge the phone and makes it do all sorts of things by itself.
just a warning to others, you may want to spend the extra money on a charger that specifically says it's compatible.

This is definitely something to do with Capacitive touchscreens.

How bad is it to our phones ?....
I would like to know what is really happening.
Is the usb charger "ground" at an important voltage relative to earth ground ?
Is it at a variable voltage, which would even more confuse our phone ?
Could we safely ground it, and how ? (connecting the usb ground to earth, maybe via a grounded 220V plug ?) .
I think anyway I will at least mesure the voltage (and maybe leaking current relative to real ground) level of this usb "ground"...
Any electronician to explain how it is normally done in quality chargers ?

I'm not sure what ground here is! My e-bay travel charger 4.7v 500mA with a Samsung logo has no ground connection on the charger - normal in Europe. Problem probably is that it is possibly not a Samsung unit at all - well it only cost 1euro - It does charge and the screen does freeze until I disconnect it. Only got it today - but nothing is getting hot and no other problems so far. The voltage rating is of course less than the standard 5v.
Bought a Belkin Dual USB car charger (1.0A + 0.5A) online. Will report back.

My best shots would be no ground (mass) issues, but:
1. stability of the charger output voltage
2. stability of the charger output current
3. value of the charger output voltage
4. capacity of the filter capacitors in the charger (too little - 50/60 Hz hum is distributed to the output)
5. Is the charger impulse or stabilized?
Capacitive screens must be very sensitive to changes of impedance and if there is no stable voltage or current or if the output is interfered with electrical network hum, the touchscreen may go crazy in my opinion...
edit: format tags corrected
Working fine without any capacitive screen issues.
The good thing is it works as charger mode instead of USB. So I assume the 1.0A socket would actually charge faster than USB mode.

It will be high-frequency noise on the DC output voltage of the charger. Chargers use a high-frequency DC-DC converter method and the cheaper ones don't do a very good job of filtering the high frequency out of the DC at the other end. This noise enters your phone and plays havoc with the sensitive circuits in the capacitive touchscreen.
It is nothing to do with grounding of the input side of the power supply; when you ground the output side (the USB plug) with your hand, your body capacitance filters out some/all of the noise.
You could probably filter this out by adding capacitors or whatever but really, the solution is don't buy $1 chargers for your $x00 phone.
Plugged in Transformer last night to charge it up overnight when the battery hit 30%. I updated the firmware yesterday morning and everything was going swimmingly.
Woke it up this morning, and found it was at 9% battery remaining and had a low battery warning. I had a closer look and the battery icon shows no indication that it's charging when it's plugged in.
Right now I've plugged it into a bog-standard USB charger and turned it off, hoping it'll trickle charge (damn the lack of a charge LED!) and that it's a fault with the power adapter rather than the device itself.
Anyone else had this issue?
I had the same problem a few days ago, my charger was plugged in via a multi block and it would not charge.
I even went to the extreme of taking my device back to comet in the hope I could swap the charger out with their demo unit.
Man behind counter plugs my charger into some sort electrical surge protected socket and it starts charging straight away leaving me looking like a right tool standing their. (and they tried to sell me 3 years extended cover)
Brought it home and plugged it into the very socket where it wasn't working and what do you know? It starts working!
Not sure what the issue was but it now works again.
Ok well that's good to know!
On trickle-charge it's now gone up by 2% since I posted.
Looks like the power adapter has its own faults...
Oh, and what do you know... plugged wall charger back in (it's been unplugged for 20mins) and now it's all happy and charging again.
Hooray.
yeah maybe that 20 minute trip to comet fixed mine too..
the USB mains adapter plug has a fatal flaw - the middle part of the usb connection isn't as sturdy as it sould be so it is easy to plug a USB port in the wrong way around and it looks and feels plugged in correctly as the middle part just moves out of the way.
If it isn't charing always check to make sure the USB connection is in the right way around in the plug.
I am bummed about this proprietary power connector; and apparently proprietary USB cable with extra pins (negating the use of USB extension cables). I wish the TF had a standard round power adapter similar to the Acer A500.
Thank God, i thought i was the only one. Had exactly this problem with mine when it arrived a couple of days ago, i am lucky enough to have lots of USB chargers around so i tried and tested various combinations and tried to charge other devices with the asus charger.
The problem lies as far as i can see, entirely with the charger unit. The charger comes in two parts, one is the usb dock and the other the relevant country plug. The way the plug fits onto the face of the charger is the important part. There is a central 'locating pin' made from plastic and two contacts that slot into the charger carrying the live and negative. The construction of this part is very, very poor. The tolerances are not a match for the quality of the plastic, the T shaped plastic locater does not actually locate the bottom pins properly and needs a great deal of force to lock in placce, and here is the best part, it doesnt like STAYING locked. As the plastic is weak, and we are looking at just a couple of mm here, it will snap, that will stop there being a clean contact and no charge. As a remedy, i have secured the face plate to the charger very tightly with a high tech rubber band
I agree, the use of specific power connectors in this day and age is just as dumb a decision as any manufacturer can make, and the rate it recharges at from a USB to PC connection can only be described as comical, a full recharge in 26 hours . Aside from all that its nigh on perfect, but i can see power related alternatives being VERY popular until Asus catches up with the rest of the electronics industry.
havent even had mine an hour and i havent done the update because its not at 50% and it will not charg at all. when i first tried to start it i thought it was doa because it would not turn on. guess ill take you guys advice and leave it unplugged for a while. i hate the charging cable is so small too that definately sucks.
Hmmm... if only a few other people created topics about not charging...
Okay so my usb port has been a bit annoying the past week - where i had to vigorously wiggle the cable to get it to charge or to sync (and even when it did decide to connect to the computer, it would chop out eventually)
But now it's no longer charging or being recognized by my comp
It's strange because the headphone adapter was working fine, and so was the usb host, but it just wont charge anymore - I effectively now have a dead TG01
Currently, i'll get the orange light, telling me it's charging, but when i try to power on, nothing happens...
So i'm thinking a new USB port which is where I need some help: I'm not sure on what part to get
But maybe This is the one? Comparing the images with the ones found on the net of the TG01 (Yep - I still haven't got mine open yet)
But yeah, just a heads up on whether you think it would work would be epic, or whether you think i should just try a different battery/charger/throw it away (Although i'm almost certain it's the port, as it was working intermitently before - it's now gone altogether)

Wall charger, but i tried USB, and still no luck
It just wont charge at all, regardless of the orange light when plugged in now that it's off (though i wouldn't get it when the phone did still have charge left and was therefore still switched on...)
BUMP: Any ideas you clever people? Just some guidance would be nice...
I'm still without my beloved TG01, I'm having to use a **** old Samsung G600
I do have some problems of my own with my USB cable. I believe the problems are due to the cable, though. The wall charger works fine. The USB cable that I use, has to stay somehow "forced"... imagine having the cell laying face up on a desk. The USB cable gets out and is forced by a small pen that stays right near the cellphone, to have a 30% slope upwards, so pushing a bit the cable onto the upper part of the USB port. I do know that you are telling us a different issue, however, maybe this way you could check whether it's just a broken connection and not a completely dead port.
No, this sounds like the exact issue i had...
It was like this with the Charger and USB - where i had to force it to be recognised or charged, and it would still cut out after a while - and wiggling it or knocking it wouldn't actually affect it, it would be of it's own accordance...
But it was strange because the headphone adapter worked fine...
Nothing happens at all now though
Are you try: Settings- Connections- USB to PC- unmark Enable advanced network functionality
I can't turn the phone on because it wont charge, so it's not that
Battery may be defective. Try with any 5V charger, connect directly to battery pin in 10 min
Hi
It vaguely remembers me of something I read on the forum about different micro usb (explaining my different cables do not connect just the same, some easy, some bit forced); I think there also was a drawing. (but I don't have time to search for the exact thread; it was not the "solving usb port mistery one))
Maybe your earphone adaptator don't have exactly the same as your charger? And if it is not battery trouble, find a charger with the "very right" micro usb plug?
Thank you both so much for your response:
I understand why you say it could be the battery problem with the charger - but it doesn't explain the intermittent connection with my computer when using the USB cable. Which is convincing myslef more and more that it's a port problem
One solution for now would be to buy one of these cheap external battery chargers from eBay, but it would mean i still wouldn't be able to use sync using the USB cable and i'm a bit conscious on whether the charger is safe and wont fry my battery
Which is why i'm leaning towards having a stab at reparing it myself
It'd solve the issue directly and it'd be a safer and more secure solution too... (the external charger would have to be ordered in from Hong Kong eBay)
I'm having what seem to be exactly the same problems. I have used 2 x usb based chargers on it - and neither work (whereas they had been working for the past 6 months). Got a mains charger last week - was working for a while - but as of right now, no longer works.
I'm not sure what else to do. I will try later to use the other adapter I have for connection to usb keyboard. The strange thing is - this will probably work but charging won't!
So....is it the micro usb port that's broken? (strange if it is but still works for data)
OR
could it be the battery?
I bought a MHL Adapter (microUSB - HDMI) from DealExterme [1].
It works well, even without power, but when I put the original charger (2A), the S4 starts charging but can't even hold the charge. The charge will slowly dropping over time.
Is this normal?

Yeah this tends to happen when the phone is draining more battery then the charger is charging the phone.
Even with de 2A charger? This is a lot of power!
Not sure if that's what happens or the MHL adapter that doesn't pass the full 2A for the S4.
Someone who has the original Samsung MHL adapter can tell if the same thing happens?

Can you confirm that by using the official Samsung adapter + 2A charger the phone battery doesn't drop?

Firstly, I don't have an S4, but I do have a Note 2 which also comes with a 2A charger. In my experience when using an MHL adapter the phone will only charge very slowly at best. If you are making it work hard, the battery will slowly drain. If I understand correctly, this is because of a limitation regarding how much power a normal USB port can supply.
When your phone is connected to a wall charger, go into settings and 'more' and tap 'battery'. At the top it should tell you it's charging, and that the type is A/C. Now plug in your MHL adapter, and plug the charger into the MHL adapter and go back into the same settings page - on my Note 2 (and also my HTC Sensation), this page now shows 'USB' instead of A/C. If the same is true with the S4 (and I'm pretty sure it will be), this is the source of the problem. It wouldn't matter if the charger was 1A, 2A or even more, the phone will only draw so much from what it thinks is a USB port. It's a pain, but there you go.
When you connect your phone to a TV via MHL, try lowering the screen brightness on the phone to minimum manually. If you have a quick search, there's also an app on here that should allow you to power of the S4's screen completely and still allow you to output a picture to the TV. Sorry, I don't have the link to hand.
Its the cable. The MHL cable is just a poor cable, if it says USB like Ouzo says then you would need to short the data pins on it or use a charge only cable (the charge only cable may not even work though).

I get the part that my MHL adapter might be delivering energy in "USB mode" instead of "AC mode".
My big question is: by the report of "big samm", it seems that the original Samsung MHL adapter does not suffer from this problem. Ie: it delivers energy in "AC mode". Is this true? I can trust and spend $ 40 on it?
If anyone can confirm, I appreciate!
I would just go for a real one from samsung so that way you won't have any problems with the battery charging because it's designed to charge + play

Ah, ok, I control my phone with a Bluetooth keyboard with built in mouse (works very well for many things, but not games designed for touch input, though there is an app to help with this in the Play store), I didn't realise you'd still want to touch the screen.
Maybe someone with a genuine Samsung MHL adapter can tell us what the battery screen shows when theirs
is in use with the Samsung charger attached. Also, you could ask nztechfreak, he knows all about such things....
Ok i just checked the manual again and it says " Use only Samsung approved chargers (over1a) there you go...

This is simply beyond ridiculous.
First, let me clarify for couple people that barged in here. This problem has nothing to do with official/unofficial stuff.
I have genuine Samsung Galaxy S4, I have genuine samsung mhl 2.0 adapter, and I have genuine wall charger (2000 mA) as well as the usb cable. You can't go more official than that.
And EVEN with all that, the battery is being drained quickly, despite the mhl adapter being connected with the wall charger. This is simply beyond belief. OBVIOUSLY the phone will be on high usage when the mhl adapter is being connected, because it's the whole point, so did Samsung actually took care of the bigger battery drainage at this point, in connection with charging current? Nope.
You cannot go couple hours before the phone is dead, despite being "in charge mode". The customer uses official samsung stuff, it connects the charging cable, and yet the phone is not charging (just the drainage is slower).
If I met this Samsung CEO that is the first one on the stage to present the cashing cow everytime new galaxy is being presented (well if that's the case he is the first one to ask about his product ain't that correct?), I would ask him about this and would keep nagging this problem to him until his ears would bleed, and he would promise it will be fixed in the next update of mhl 2.0 adapter.
And just to make it clear, the problem is not with the battery drainage, but with the current being suplied from the mhl adapter. If it was 2000 mA, as it is when you connect the phone directly to the wall charger, there would be no problem. Instead it is 500 mA, as it is when you connect the phone to USB port, and because of that, the phone is dead in the manner of hours, despite "charging" (pun intended).
Amazing.
i tested i9505 with his original wall charger.
Original charger with original usb cable consumption is 1200mah
Original charger with other usb cable consumption is 460 mah
So first is important to use original usb cable.
Then i tested compatible mhl cable with original charger, its consumption is 300mah.
So the problem is the slow charging even with kernel with fast charging.
I ordered original mhl adapter, i will test it when come and post result
I'm late to the show, but will report my experience as well.
Last month on stock TW MDK using all genuine Samsung including a MHL 2.0 adapter, I also experienced battery depletion and a hot phone. I failed to check the Status to see whether it was charging at APC or USB rate.
I attributed it to the screen being on and the phone streaming movie data across the cell network.
Just now, I plugged the MHL 2.0 adapter in, then the charger, but not into HDMI. It shows USB for two seconds then it says AC on the phone Status. Same thing a couple times in a row. Plugging the charger directly into the phone goes immediately to AC charging.

When constantly connecting and disconnecting the wire to charge with the regular cable, the plug on the phone gets looser and looser over time.
Also, if and when someone might knock into you with the wire plugged in, then it could make your phone fall to the floor possibly causing it to get damaged.
These are just 2 Very good reasons why a Magnetic Cable is a Good Option.

It's Not only for Data Transfers.
When you have a Low Battery and want to charge your phone with a Battery Bank and are also using your phone while walking around and someone or something bumps into or snags the wire, your phone don't get pulled out of your hand.
Also, what about when you have pets that jump around and knock into you or your wire? I constantly have My dog that jumps up on my lap and down when he wants to get down for whatever reason. Sometimes he catches the wire and My phone still stays either in My hand or on the arm of the couch.
And lastly, when you want to charge your phone in the car, you don't have to concentrate on plugging in your phone. Just put the end of the wire close and it connects on it's own and charges your phone.

Ah, gotcha. Out of personal habits. That makes sense. Personally the only time I've got my phone connected is to transfer large files and that's rare. I wireless charge almost exclusively, home and on the go, so I don't have to suffer the consequences of any pets or people pulling any cords out. Wireless is so lovely.

Yes I have, and they either don't know the True Charging Speeds or don't know the exact Specs of the Cable.
For a QC3 Cable, it would have to be a USB 3 or USB 3.1 Spec Cable. Most Cables are USB 2.0 and most people think that's a QC3 for a Magnetic USB Cable.
A USB 2.0 Cable that Plugs into a Phone Will Quick Charge, but that's NOT the same as a Magnetic Cable.

I'm Interested to know if Anyone know about a 4 foot to 6 foot Magnetic USB C Cable that Will be able to Quick Charge at QC3 Speeds so the Slow Charging Message won't pop up every time the connection is made.
Please attach Snapshots of the Phone saying Quick Charge and the Cable before and after connection is made and a Link to where to buy it.

Using the QC 3.0 chargers won't charge the Note 9 at QC 3.0 speed. Note 9 itself only supports QC 2.0, so when you plug it to QC 3.0 charger, it will still charge at the speed of QC 2.0.
These support QC, I've tested with my Note 9 and it fast charges fine. I've confirmed with an in-line USB power tester and it's going up to 9V and is able to supply as much currently as the other non-magnetic USB cables I've used. Data transfer is also working with this cable.
Hi guys the cable from nu wave supports fast charging of all Samsung devices. As you know quick charge 3.0 magnetic cables are backwards compatible with 2.0. But these cables also support Samsung AFC. They have a video demonstrating generic magnetic cables but the actual cable in the product description and images is what you get which supports the above technologies.
