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.
Add me to this list as well.

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.
I have the problem with non-oem...oem is just fine for me
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
Since I couldn't find any solution to my problem anywhere, I thought I'd post my solution here in case someone encounters the same or similar problems.
First, the problem: When my Galaxy Nexus is connected to my TV, using the samsung mhl-to-hdmi adapter, it loses connection at times. These problems get worse when the battery is low. It seems like the charger cannot support both the HDMI and the phone at the same time.
Resolution: My TV happens to be located in an area of my appartment with particularly bad reception. It appeared to me as if the disconnects happened whenever the phone was searching for a network. When the phone is in airplane mode the disconnects no longer occur, even if wifi is active. I haven't yet checked if it is enough to just switch off 3G, but it works and I'm very happy with it.
Activate airplane mode in Settings > Wireless & Networks
If you wan't to have wifi, just turn it back on.
I will have to test this theory
I have read that with the MHL adapter it works much much better to have your phone charging at the same time.

The MHL adapter is supposed to charge your phone through HDMI. Not sure what you're trying to say here.

A Million thanks to you dude. You made my day. I would have definitely given you one strong hug if you were anywhere near me.
I bought a brand new Samsung MHL and a High Speed HDMI two days back, only to find frequent disconnection and white noise. Happened every few minutes. Tried everything and was so freakin sad that I can't tell. Searched thoughout to find a solution. No go. Neither XDA nor google had the answer.
And then finally stumbled upon this thread.
And its exactly what was happening to my galaxy SII. I was in a place of low reception where 3G strength was bad. Never thought of this to be a problem.
But finally I read, I followed, I implemented and there I am.
Extremely satisfied with my purchase and my SII. It was back up and roaring on the big screen clutter-less now.
Thanks again dude!!!
Just one thing. What do you think is the relation between the HDMI output and network strength?? Is it supposed to happen or is it a fault(H/W or S/W) ?

MHL adapters include a side port for charging your phone. When your phone is displaying itself through HDMI it drains battery faster than this 'HDMI charging'. If your MHL adapter doesn't include this, I suggest buying a new one. $7 on eBay.

I believe that for most (all?) MHL->HDMI adapters, you HAVE to plug it in.
In MHL mode, the phone is set up so that it is able to receive power (charge). The MHL->HDMI adapter needs power to run. Since it can't get power from the nexus (because the nexus is set up to receive power, not provide it), it needs to be plugged in via the side micro-usb port. So far, all the adapters I've seen/heard of are this way.
Hypothetically, I suppose that the MHL->HDMI adapter could be battery-powered or have a different plug to provide power - or it might only power itself and not the phone. I've never seen one like that, though.

I believe you are mistaken. First off, the maximum power capable of being supplied over HDMI is 50mA - well below the charging requirements for the Nexus. Secondly, the device you're connecting the Nexus to (TV/Monitor) is a sink device which does NOT provide power (unless MHL compliant?) to the source (Nexus). Thus, most (all?) MHL adapters provide the option of connecting an external power supply to charge the device.
To the OP, thanks for this info! My friend had issues with his and this could very much be the issue, the low signal is causing too much power draw for him.
Since I live in an area with very strong signal, that would explain why I never saw it.

Ah, yes - good point.
I just got a brand new MHL adapter and cant get it to work at all. Beginning to think I got a DOA one.
I am going to try your solution to see if it helps, but I have good reception in my house.
When I connect mine, with power attached to the adapter, I get nothing at all on my TV, and the phone does nothing either. What could be wrong?

Does your TV support 1280x720 over HDMI?
Awesome! I've tested this last night and didn't get any flickering of image when using my MHL to HDMI. The flickering would happen every 30 min or so sporatically...
FYI- your phone does not get charged through HDMI cable. You need to plug in power to the MHL connector to even use it which charges it but having the screen on at all times causes the battery to slowly drain. I usually just dim my screen down as much as possible to savage what I can. The drain is very minimal ~ 2% per hour with the type of MHL cable I purchased. (Menotek Micro USB to HDMI MHL Adapter IMPROVED WITH RCP- purchased on Amazon)
I know it's an old thread, but has anyone else tried bumping the CPU minimum up to 700mhz? I am going to do this tonight, airplane mode did work for me but I am currently looking for away to get HULU and Netflix working and I need the data connection.
Thank you so much, it works. Anyway, is there a way to have data connection and mhl at the same time?

Try it for your self, but if you are using any of the newer ROMs with the new DDK1.9, it doesn't support MHL.
I seem to have an issue that my phone never charges whilst connected via USB to my Macbook Pro. I have also tested on a Windows machine and have the same issue.
I was able to charge my Sensation over USB and I know that one of the ports on the Macbook has a higher output for charging but it makes no difference.
The phone states that it is charging but the percentage charge continues to drop. If I switch the power off it will charge. There doesn't appear to be any big battery drains though. I ran for a day and twelve hours over the weekend and charged at 40 percent.
Has anyone else the same issue?
Btw, I am on stock 4.0.2, rooted but not running anything else that should have any affect

How old is your macbook pro? Or more to the point, do you know if it has USB 3.0 ports? If your higher output ports are just 2.0 (and your computer is describing them as such compared to the older 1.0 spec) then you are stuck at 0.5A (half of wall charger output). USB 3.0 goes up to 0.9A, but I don't know if there are any catches in terms of devices needing to request the bump.
When you say that it charges if you switch the power off, do you mean it only works if you actually power down the phone? As in, leaving it sleeping plugged in, it still won't charge? Keep in mind that actively using the phone with the brightness turned up high could result in overpowering the .5A current in.
Unless you know someone else with a GN you can test you might just want to take it into the store and have them try it there/consider a replacement if it's defective. Also worth exploring if it's just the battery is defunct, if you have access to another one.

Really? Source?
Doing a tad of research it seems some models front (closer to the front) USB port has slightly higher output than the back (closer to the screen) USB port because the back one shares a USB controller with internal components.
It couldn't be noticeable though, they're both simply rated at .5A .

MacBooks don't have USB 3.0. Its always been standard USB 2.0 afaik.
I'd also recommend that OP check different cables and computers, or different batteries if possible.
I have the exact issue. If I charge via USB on ANY laptop/computer it takes forever and if I'm using the phone as it's charging it uses more power than being supplied so it loses battery life even though it's plugged in.
I had this problem on my iPad too. It seems they need more power to charge but can still "trickle" charge off of a standard USB port.
My batter was at 10% last night, plugged it in to my laptop and sent some texts and left the display on (dev settings), about 10 min. latter it was at 4%.
I mean to post this last week!
See the screenshot....Status 'Charging' however as you see from the lower part of the screen, it has clearly stopped charging some time ago (about 3 hours earlier!)
It turns out that the CABLE was the issue....I thought all Micro USB cables were created equal, evidently not
Any ideas what the differences are in micro USB cables and how to identify which ones 'work' and which don't? I bought 10 from ebay which all seem not to charge from USB
I've had no problems charging via my pc using Samsung or Motorola cables. It charges slower but it still works.
So i picked up a MHL adapter and have been outputting the phone to a monitor. Worked great. Then the only thing i did different in the next few days was installed Francos Kernel Updater, and enabled Hotplug Mod and USB Fast charge.
What happens is you connect the adapter. The screen flashes then goes black. If i turn th screen on or touch it, its fine. But as soon as i stop interacting it goes black?
It used to not to that. any ideas?
Try disabling USB fast charge.
Also, how is the signal where you are? I have heard people encountering issues when there is low signal and extra power is being drawn by the radios to keep a lock.
Just tested this mysself since I installed the Franco app yesterday.
I have hotplug mod and usb fast charging both on.
MHL worked perfectly for me. None of the issues you describe.

I was using an OEM MHL adapter at first, and had the same problems you describe, i.e. screen goes black. It was also flaky with my wife's Samsung Skyrocket phone.
I returned the OEM MHL adapter and bought the Samsung adapter; this adapter has worked perfectly, for both Galaxy Nexus and Skyrocket.

Are you using a HDMI > DVI adapter? if so, check this post out. I have similar issue you had. Seems like some people fix it by using a different ROM (I can't confirm that because I'm on stock 4.0.2 ROM) or just accept it and find a monitor/TV with HDMI.
