Hi Goodtilltomorrow,
Would like to help, but what is the question?
If you are charging via the USB connection then it will ask you what type of connection you want (whilst also charging).
My solution for charging only, is to select Disk Drive and then to 'safely remove device' using the icon in the system tray.
That way the device is not using any additional power (above normal standby) but is charging from the USB port.
If it's asking about activesync or Disk Drive via a mains power source then I am as confused as you.
Hope this helps.

oh sorry.
i meant to ask, why is it asking where im charging from everytime i connect it to charge from the wall?
im using the stock charger and it never use to ask me where i wanted to use (Activesync or Disk Drive) when i just charged my phone from the wall.
how can i get rid of it doing that?

Does it charge at all? Mine does the same, but doesn't charge at all when the phone is on.
I can only charge it with the ac charger when it is turned of, or turned on using the usb on my laptop...

yeah my charges. its charges even with the phone on.
i wonder why it does that!

every so often my charger does the same.. some pins must be pressed somewhere in the usb input. I haven't seen it negatively effect the phone in any way though.

no, it charges it which is fine but i hate it opening having to turn the screen off again and closing internet sharing everytime i want to charge it

Tab is going into MTP mode and wont charge.....

This is hooked up to the Samsung charger , I have-no idea what the heck is going on..... anyone else?

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?

Phone doesn't know it's plugged in.

When the phone is off and plugged into the wall, it charges. When the phone is on, and I plug it into the wall or computer, the phone doesn't know it's plugged in.
I ordered a brand new usb charging flex jack and replaced the old one, still the same problem. What gives?
EDIT: I am stock. Not rooted.

Does this happen on the original cable also?
Have you tried wiping?
Is Fast Charge on?

Fk. It doesn't even charge from the wall! When the phone is off, it has the animation that says it's charging when i plug it in the wall. I left it plugged into the wall overnight. This morning I took a look at the phone, and it didn't charge!
Oh noez, what should i do?
Also, I don't have the original cable. I'm using an HTC one.
EDIT: Dafuq?! I found an LG charger. Apparently the phone knows that it's charging when I charge with that. The thing is, that charger is just a charger; it's not a usb cable+ an adaptor. So I can't use it for adb and such.
What is Fast Charge?

You should mention what ROM you're on (and version) so that no one else makes the same mistake I did in assuming you had a custom ROM and that Fast Charge is on. It's a feature that makes sure that whatever charges it is recognised as AC 1amp charger as some chargers aren't designed well enough (I believe it involves a single solder point) to report themselves as capable of 1A. If it doesn't report as AC to Android, it will charge at 500mA instead (it assumes USB power). It sometimes causes problems with connecting to PC via USB.
Get another USB cable, this time none of that fancy **** go straight to OE Samsung or something.

=O I thot all usb cables are made equal! So I can't use an HTC usb cable? The dude didn't sell me the phone with a cable T.T
Also, I'm stock. I am not even rooted.

My nexus just started acting stupid when I plug it in also.
Mine sat in a drawer for a few weeks and when I plugged it in to charge, it wouldn't.
What I did was this.
plug device into charger
remove battery for a few seconds
replace battery
press power button
phone powered up and began charging.
Even now, it still sometimes doesn't recognize the charger and I have to unplug and plug it in until it does.
I use a rocketfish cable.

Some devices are picky, you'd think that all USB cables are made equal (I did too) but some just don't work well with certain devices. I've had printers th... wait printers always have **** problems... I've had uh... usb extensions not work well with some Wifi dongles and such. My old milestone didn't like the Samsung cable either (yet the Moto cable works perfectly on gnex)

=O. Then it has to be the usb cable! No way it's not!
I ordered one on ebay =D
Rooted Gnex here I come!

Thank you dmappdev,
I followed your procedure (feel like talking about surgery here, which isn't too far from topic); I'm convinced that it helped in some way, directly or indirectly... as at first, my Galaxy S Advance still wouldn't recognize/charge my phone with:
1. its own charger,
2. my old Galaxy Ace's charger,
3. a universal wall usb plug used with the S Advanced own USB-to-USBmini cable.
My last idea was to use, quote: an old Nokia USB cable connected to my PC... and that worked.
I was much too happy my phone had remembered how to charge to stay mad... But I still tried those three means for charging again, and only the phone's original charger worked now. So the phone's charging ability has been "awakened" in some way, but only for the original charger ...technology is improving, but not the ethics on making life easier for the consumer.
All this was yesterday. This morning (there's more, yes), I saw my phone indicating a 100% charge although it had been disconnected from charge for several hours - something that had already happened once yesterday, before the unable-to-charge situation; a simple reboot took care of the problem, the battery status now showing a more realistic 53%.
Any comments to any of the above? If not, thanks again for your tip anyway !!!

[Q] Charging the phone

Some chargers just wont charge my phone, for example: iPhone's original charger or a powerbanks portable battery...
My guess is that the voltage is little bit different than the original wall charger and the phone wont charge from it, is there any soft\hard mod to overpass this issue?

What? Iphone's original charger? I don't think it won't ever can be used by our phone. Because it is for iphone. If it is a blackberry charger it can work but not all of it.
For powerbank maybe there is something wrong with the usb cable because mine can work well on every powerbank. Except the last one i used it didn't work but after i change the usb cable it works flawlessly.

By "Iphone's original charger" I mean the wall plug that you can pull the USB cable out:
[see attached image]
I've tried with three different cables.
BTW, I tried Powerbanks super magic stick, nothing happens when I plug it in...

Why don't use the original charger from the phone? It is definitely compatible though. But for the powerbank i don't seem to know. Sorry for my limitness

I've opened this thread especially because of the Powerbanks issue...
iphone's cherger is only an issue that I've mentioned because it may help to understand the problem.

why?
May I know why you keep calling your charger as iphone's charger? You realise that you're using an Android based phone right?
Is your original Android's charger broken? Why not just buy a new one? Or maybe asks for replacement if it's broken from the beginning.

Oh okay. Is your powerbank working on other devices except your wonder?
Pressing "Thanks" button will be much appreciated if user's posts useful for you

found a way to make it work
I solved my own problem..
It seems that if the connected device is not sending data (like PC or car host) to the phone the device wont charge.
Also I found out that the charger short circuit data+ and data- pinouts so the phone knows its the charger.
All I had to is cut a usb cable in half and connect green and white wires together (on the phone's side)
Not the chargers side! (to prevent potential damage)

[Q] [Help] Tab S 10.5 Wifi no charge & no power on

Hello,
I have a Samsung Galaxy Tab S 10.5 Wifi with the following things:
- stock rom
- root
- twrp recovery
- skyhigh tw kernel
Before going to bed, my tab was at 7% charge and I put it on charge.
The next morning, I got my tab and was unable to power on...
I unplug then plug again the charger without any reaction from the tab... no sound, no vibration, no green battery saying "Hey I'm charging..."
I sent my tab at my local official repair center (I'm in France) and they refuse to repair it because of "It's rooted man" !
How can they say it is rooted without powering on ?
How root the tab disable charging it ?
How can I gain right and force then to repair my defect tab ?
In Europe, any soft modification disable soft warranty but say that hardware waranty is still available !
And if defect happen in first 6 month then the defect must be there since origin.
I'm not sure if my english is good enouth to be clear... But I really need help
PS: I have a thread about this on a french forum...

Maybe the cable is bad or maybe the charger is bad. Those are the first things I would look at. The Tab S will charge on a computer's USB port. So use the USB cable it came with and connect it to the computer while the computer is on of course. If the battery is totally discharged it may take some time for it to reach a level of charge to display the charging indicator, so leave it hooked up for about an hour then check it. If it charges on a USB port then the cable is OK. If it doesn't, try a different cable on the USB port.

Maybe I forgot to say that:
- the charger is ok (tested on my S4)
- plug on usb computer don't even woke up the tab
- I left my tab charging for a night with my working charger
- I tried my S4 charger with same result
Thanks for your replay but, I already tried all these steps...
Now this is between me and Samsung Customer Services...
(and this is bad because I really like Samsung, S4 and my new TabS... kind of rocking tablet)

I just read it... I tried to let it charge but I cannot charge anymore... You can...
You can resetting battery stats and see if it change something... I could not because I even can power it on :'(
I hope you will solve your problem just by clearing battery stats !!!

Connect your tab at your pc and leave it there for more than 30 minutes...then for me battery starts charging...
