Hey guys. Got an aftermarket charger after my original gave up on day one and i didnt want to have to send everything back. When i plug the phone in the scren becomes un responise, but the hardware buttons stil work. Can anyone explain this? obviously i ned to try a diferant charger, specificaly for the galaxy but how can the charger stop the screen working? Many thanks.

Yes the same thing happened to me,,i took the charger back..and got a proper one
just for reference, the Black Berry 9600 chargers are compatible with SGS 9000
i bough one for car use
So are the moto chargers.
My car charger is an old razor v3 mini-usb with a mini-usb adapter.
My wall charger is an old Razor v9m charger.
Never tested a BB charger as i have always charged mine with the moto ones that were already plugged in
yup i also purchased a mini usb to micro usb adapter to use my old Moto chargers with my SGS
The same happened with me while using the stock charger in a train. The capacitive touch buttons and the screen stopped working, but the hardware buttons were working. So I plugged in my laptop and used a USB cable for charging it.
Never heard of this before....
I've not come across a charger that does not work.
The chatger works but the phone doesnt while its plugged in! my back button and menu button still work along with hardware buttons...... Weird... Allready ordered an official replacement

That will be the cable that has issues.
Pity you couldn't have tried another cable.
I am using a nokia car charger, also works fine. Blackberry didn't work for me
Yeah i know the cable causes the issue but does anyone know how? obviously other after market chargers are ok... Phone charges fine too, just cant use it when charging...
Sent from my GT-I9000 using XDA App
i'm using After market chargers too, but i have no problem
my car charger is using a BlackBerry 9500 charger (2A)
an in my PC i use a Motorola sync/charge USB mini + micro USB adapter to make it compatible with SGS 9000
they all work fine
i have not even unpacked my SGS usb cable that came in the box
Is any of this chargers really recognized as charger (charging with more than 500mA)?
You can easily verify this with the app "OSmonitor".
IF you see this: "USB Power: Online and at AC Power: Online" everything is working as it should. But if you see "AC power: Offline" your phone thinks the charger is a pc and it will only charge with 500mA.

The only problem with software informers here though is for those that have the problem and the screen locks up whilst being charged the software is of little use.
This question was not for people having a faulty charger but for the ones claiming that they have a functioning charger!
If the charger is not really recognized as charger it is useless for navigation. As the Galaxy S need more than the 500mA while navigating (with GPS).
yeah, minimum you need a 1A (1000mAh) charger
that's why i prefer the 2A chargers, it gives just enough juice to actually charge the battery, and use GPS+3G+WiFi+Bluetooth
else the car charger will not even be enough to power all those, and it will still consume the battery power.
that's from experience from my HTC phones

I bought a Sharper Image Retractable USB kit that has adapters for most of the USB sockets out there. But the Micro USB that came with the kit fails to work with the SGS, the retractable USB cable is set up like an extension cable which works fine as an extension cable but putting on the adapters dont work.
Last night I had a low battery. The screen was on and I hit the side power button to turn it off and nothing happened. The screen just stayed on. After several attempts to turn off the screen it turned off all together. I assumed the battery died. This morning I plugged it into my mini to micro adapter, which I have used before, and it still wouldnt do anything. No charging lights or anything. Tried three different mini USB cables and two different micro adapters. I get nothing on any of them. Are there supposed to be any lights on the phone while it's charging when the phone is off? I really doubt it's the chargers but I suppose it's possible. Does it sound like the phone is dead? Is there anything to check?
I would pull the battery out to force your phone to reset. Plug it in to the charger and and turn it on.
Tried removing the battery several times, still no luck. Today is the 31st day. If it's the phone, AT&T better replace it with a brand new one!
I held the battery from my fuze up against the Focus terminals and pressed the power button. It turned on. So apparently the battery is flat and not charging for some reason. Will try with the original charger when I get home.

You weren't using the original charger before? That's probably why you're having issues. I've had significant issues with it charging with any cable other than what came with it. No clue why.
Figured it out. I have 3 old HTC phone chargers (120v to mini usb) so I bought a bunch of the micro to mini adapters for $1 on ebay. http://cgi.ebay.com/Motorola-Mini-U...230750?pt=PDA_Accessories&hash=item41546be29e
When I use the old charger with the adapter, it will not charge. It does on my gf's HTC Surround though so I will give the wall plugs to her. When I use the new EBAY adapters with a standard usb cable plugged into a computer it works fine. They also work fine plugged into the included 120v to USB adapter. I also bought a couple generic 2 port 120v to USB adapters, http://cgi.ebay.com/NEW-2-Dual-PORT...694149?pt=PDA_Accessories&hash=item2eb1df4185 ,
and they too work fine with a standard USB cable and the ebay adapters. It's really odd. I'm not sure what the difference is inside the 120v to mini vs. the 120v to standard USB but it was consistent amongst all of them.
I had my HD2 USB adapter at my bedside for charging my HD2. Instead of changing the adapter to the new Focus supplied one, I just plugged in the Focus to the HD2 one. In the morning my phone was dead. HD2 Adapter will NOT work, no matter what I try. I even tried my wife's iPhone adapter, and same thing. Went to the Focus Adapter, and all is good now. Strange...
Also, USB Cable to PC works fine.
PS: I read somewhere that the phone will not charge if it's turned off. Have not tested the theory, but maybe related.
I don't get the charging issue. I found out today that my phone wouldn't actually charge with a stand alone micro charger that came with one of my old BT headsets. Seems to work just fine with my car charger using the provided cable but it still makes no sense.
It's only 4 pins and a ground how the hell do you screw that up?

There are no lights anywhere to indicate that the phone is charging (other than the AMOLED screen). So, you have to check before the screen turns off. No LEDs to indicate a missed call or SMS, either - pretty annoying.
Another thing I noticed, when using the aftermarket wall-plug to USB adapter, even with the Samsung cable (USB to micro) allthough it does charge, the touch screen is very very sluggish. Takes several fast swipes just to get the phone to unlock. Can barely even type a word. This also occurs on my GF's HTC Surround. Weird indeed.

That makes it sound like a software issue since it's two different manufacturers.
Hey guys - I've been dealing with a Tab charging issue for a few days, and finally solved it... but I thought I'd post the problem and solution here in case it can save someone else a load of frustration if they run into the same problem.
From what I've read, we know that the Tab only draws .5A power from a USB socket, but that it draws ~2A from the wall, and that it knows the difference by testing for a short on the TX/RX USB data wires. (Correct me if I'm wrong on the details, but that's the general impression I've gotten.) We also know that the iPhone/iPad/iPod uses a pair of resistors instead (per the USB spec) to determine the current-delivery capability of the source. (I'm no EE, so I'm a little fuzzy on how that works from a technical perspective.)
So to set the stage: I had brought the USB cable for my Tab with me, but had neglected to grab the USB->outlet adapter for the mains. Similarly, a friend who was on vacation with us had forgotten the charging cable for his iPhone. Thinking I was killing two birds with one stone, I bought an aftermarket USB charging cable for the iPhone which had a separate USB->outlet adapter. His iPhone charged swimmingly, and when I charged my Tab overnight (screen off, starting at ~89% charge) using my cable and the aftermarket adapter, it worked flawlessly. No problem, great solution, or so it seemed...
...until I got home. Suddenly, my Tab wouldn't do more than a trickle charge - the same charge it gets when connected to the USB port on my laptop. (I could tell this was the case because of the small red 'x' next to the charging symbol in the battery icon - which I hadn't noticed while on vacation.) A 2.5-hour car trip using Navigator (screen on the whole time), even with the car charger connected, killed the battery completely. No matter what I did - shutting down apps, rebooting the device, resetting every option I could find - I could not get a fast charge to happen. Even leaving the device plugged in overnight resulted in *less* charge than what I started with if I didn't turn the screen off. I called T-mobile, talked to Samsung tech support twice... and all they could offer was to have me send the Tab back for replacement.
I was at a loss. I nearly did a hard reset in frustration, thinking I had screwed something up royally.
Then I saw the resistors in the pictures in this post:
http://forum.xda-developers.com/showthread.php?t=845844&page=3
and something clicked. I had been assuming that the *cables* were the difference between the iPhone and Tab chargers... but there isn't enough room for resistors in the cables! (Well technically, there is, but regardless...) The resistors must live somewhere else... and, I reasoned, that somewhere must be inside the USB->outlet adapter. So I pulled out the 'proper' Samsung adapter, plugged in the Tab, and voilà... a perfect fast charge.
So this is why the Tab won't charge with an iPod (or Sony-Ericsson, as it turns out) mains USB adapter OR USB-port car charger: the circuitry to let the device know it's capable of a full 2A delivery doesn't live in the Samsung cables; it's only present in the adapter. If that's not there, the device thinks it's connected via USB (and will, in fact, say "USB Connected" every time the charger is plugged in) and won't charge more than a trickle.
So that's my story, and hopefully it can save someone else some pain and frustration. Thanks for giving me the floor.

I've recently seen (somewhere) a usb pigtail cable that shorts the pins to make the tab (or any other usb chargable phone) think it's hooked up to a wall charger, rather than a trickle charging usb port.... I need to find that again and just order a few to have in my various cable bags.
If you do find it again, please post it here. Definitely something I'd like in my bag of tricks as well.
Just as an FYI, the 2A charger that came with my Nook Color charges the Tab just fine from mains, even indicates charging. Makes sense, since both devices have a 4000mAH battery.
It's also a nicer unit for travel, it's nicely rounded, the prongs fold into the body of the charger, and you can pick it up from Barnes and Nobles stores just about anywhere in the US. Still doesn't solve the Tab cable issue though.

I'm planning on hacking apart a spare Tab cable so that it goes to a female microUSB; no more multiple cable types then. The stock Tab cable doesn't appear to have more than 6 pins, of which I'm sure a few are grounds.
Someone recently posted a link to the first cheap 3rd-party cables:
http://www.dealextreme.com/details.dx/sku.51931
Get those with a 6' USB extension cable and the Nook charger, and that may be a winning combination. I ordered four the the charging cables yesterday, and I'll try to remember to post whether or not they work out well.
Resonance, what are you planning on using for a car charger, if any? I really like the Navigator app, but it's just not practical if I can't keep the Tab charged while using it.
Does anyone know if there are any USB->12v adapters that have the right circuitry for the Samsung? For that matter, do any other devices use the same amperage detection setup the Tab does? It would be good to know what components are cross-compatible.
Thanks for the info.
How about a list of chargers that work fine on the GTab.
1. Garminfone charger (1amp - works great and I use it as my primary charger)

A 12V inverter, attached to the standard wall charger. :/
I bought the Duragadget 12V->USB charger, since it was advertised specifically as a 2A charger for the Galaxy Tab, but it DOES NOT work as advertised (the Tab treats it like a any other low-current USB port, and even offers to mount mass storage, heh).
Using the inverter and the wall charger worked just fine, though it was a bit clunky and unstable (on mine, the prongs aren't tightly gripped, so it bends out of place easily).

Good eyes. I thought it was a different unit with an integrated cable.
Has anyone found a functioning 12v charger?
yes, the verizon store has a 12v charger for the galaxy tab, but that was the only place I was able to find one... other than online.
Hi,
Can anyone else confirm that the Nook charger works for the Tab?
I've tried other high current (2.0+ amp) chargers. Some designed for the ipad and some not, and I always get the trickle charge icon and it's treated as a computer USB connection (Mass storage device options, etc).
How much was the Verizon charger?
Thanks!

Hi,
Thanks for the tip. I can't find much information about the Scosche GoBatt 2 charger, or the adapter that comes with it. Today I tried other Scosche chargers, including their iPad charger, and it didn't seem to work.
Can you give some more details on the adapter that comes with the GoBatt 2?
Thanks!
Got this travel adapter by ZipKord with 2 - 1 amp outlets. Works with the OEM cord and also the Gomadic tip made for the Galaxy Tab. Just need to be careful it's not the older version that only has the lower power outlets. Cheapest I could find was $13+, so if it's less, it's the lower power. With the Gomadic tip and reractable cord, it says it's charging.

Also this Scosche battery pack seems like it would work. Has 2 - 1 amp USB ports. I ordered one and should get it tomorrow.

Sounds like you fell victim to the poor quality of the microUSB port on the HD2. If you can, I would re-flash back to WinMo6.5 and send it in for a warranty repair. If not, you're next best choice would be to send it into a 3rd party repair shop. =/ Sorry.

What? You plug the USB cord into the microUSB port and you're not getting any reactions. Sounds like the microUSB port is broken...
nonono ok have coffe mug with usb charger and 12v adapter you plug usb into i plugged usb from my usb data / charging cable into the usb 12v adapter to see if adapter would charge phone and now the phone says plug in charger when already plugged in like its not recognizing the charger is plugged in on both usb data cable i used to try the 12v adapter AND seperate charger that had nothing to do with adapter and the usb charger cable plugs into the phone
oooh ok where i plug the cable into is the microusb port i get it ... ok that seems to be fine to it was working perfect until i tried to use the usb 12v adapter to try charging the phone could the adapter have fried the charger hardware in the phone ?

Possible, the voltage is pretty high and could conceivable short your charging circuit...
All of the USB adapter should be outputting about the same since the USB ports are standardized for electrical output. I suspect your USB data cable could be at fault. If you phone doesn't react to your USB cable being plugged in, you also may want to try pressing one of the hard keys on your phone so that it can realize that you are plugged in via USB. I have that issue with my phone from time to time and just press one of the hard keys so that the phone knows it is plugged in for charging.
that somthin that can be fixed or is that a throw the phone away problem
believe me i tried ...... i pressed all kinds of buttons and no reaction.... and now the battery died so i cant do anything

I wouldn't throw your phone away... Try a 3rd party repair shop - they should be able to fix it for around $70... Expensive, I know, but it's better than spending $500 on a new phone.

I sent my phone in to repair for the exact same problem and it's in the process of getting fixed now. They even have the part to repair it. I've called and talked to them, they can fix it and they don't care about custom ROMs on the phone.
Hey all, quick question.
I have my Nexus 7 installed in my car. Originally it was getting power from a 500mah USB car charger, but it didn't provide enough power to the tablet when running GPS/maps, etc.
So I bought an "8Ware Dual USB Car Charger 5V/2A" to try. I plugged it in, and the tablet doesn't detect it or charge from it. However I can plug my Galaxy S3 into it and it charges fine.
Really confused about this - it makes no sense.
Any ideas?
Thanks in advance!
I understand your frustration and it sucks!!
But sometimes even when it says UNPLUGGED and NOT CHARGING, just leave it there for 30-60 minutes. You might see that your battery actually increase... This happens with my Griffin PowerJolt Dual USB car charger also.
You can either blame the device or you can start blaming other issues like the charger, the usb cable etc but for me, I blame primarily on the device.

Thanks for that. I tried plugging it in for a while but it definitely didn't get a charge.
Hey All.. I looked forever to find a solution. The Targus 2A car charger has a small (3") adapter cable that comes with it purportedly for Galaxy Tab. That little cable with the data wires shorted on the device end allows the N7 to be charged from ANY 2A car charger. I'm using the adapter with a Scosche dual 2.1 Amp Car Charger

Edit: I just built a usb cable with the data wires shorted on the Nexus end (cut, strip, short micro usb end green and white, remake connections red to red and black to black, insulate splices individually, wrap all in electrical tape or heat shrink for strength and beauty) and it works with all chargers. Took about 20 minutes.
