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?

[Q] Car charger recommendations

Hello. I'm trying to pick a car charger that would work with the galaxy nexus. from what I've read so far the samsung CAD300UBEB/STD model seems to do the trick but a few review says that the battery discharges faster than the charger can charge it back under heavy usage. can anybody confirm or deny this?
and also, I would like to know if that same charger would work for a galaxy S2. I'm looking for a charger than can be used with both models because I have both phones. the listing of models in amazon website doesn't list the nexus or the S2. so I want to make sure before buying it. thanks!

I'm also interested. I was just looking at this discussion on Reddit taht goes a little more in depth

The motorola charger listed there seems work well for the nexus and also for the S2 according to amazon reviews.

I went with one of these and a USB cable, and it seems to work just fine. Also gives me a spare USB port for additional charging.

I have the Motorola one already (the one with the blue LED) when I had my Droid 3, now it can't keep up with the Nexus' power drain. Just using it moderately on 3G only in the car today had it drain 3% over 40 minutes.

not according to this guy
I have a galaxy nexus cell phone which requires probably around 1.5 Amps when using GPS. The phone does not come with the car charger. It only comes with a 2A wall charger. My temporary solution has been to use a car power inverter that has house-type outlets on it (which I already had) so that I can use the wall charger in the car. This has been working fine, but for obvious reasons, is not my desired long-term solution.
Enter this piece of crap. Now, the phone and only requires a little over 1 A with GPS. With the real two amp wall charger, I am able to both run GPS and charge the battery pretty darn fast. But, with this charger, not only can I not use GPS without draining the battery, but even when not using anything special, the battery charging times are horrendous.
Stay far, far away.

Wow... granted, I am not using a GPS, but I never really checked the charge times. I don't rely on it for a fast full-charge.. usually just plug it in on the trip home and charge as much as it can until I plug it in at home.
Thanks for the heads up.. I am gonna have to keep an eye on it now.

I've researched this pretty thoroughly, and the key question is whether or not your GN shows "AC" when you check the Battery status, or if it shows "USB."
With most car chargers, it is seen as "USB" as if it's plugged into a computer, and will draw minimal current, generally not enough to keep up. I had 2 different chargers in my cars, none of which showed as "AC". I bought and then returned the Griffin PowerJolt Dual USB Micro Charger - it also showed as only "USB."
Finally, in one of the other Android forums I've been monitoring on this issue, somebody came across this one:
HTC T-Mobile myTouch 3G Car Charger
$3.12, free shipping. Mine came yesterday, plugged it in, and finally my GN showed charging as "AC".
Hope this helps!

When your smartphone shows your charger as ''USB'' this means that the USB data lines in the charger are not short-circuited. Then smartphone reduces its charging current to avoind any problems with USB laptop power sources
I made some experiments to check this point : see http://78michel.unblog.fr/?p=184.
I also opened a car charger and short-circuited the data lines on USB the plug . That way I have solved my previuos charging problem in my car during long trip.

It helped indeed, thanks for the link!

this is what i bought: http://www.amazon.com/gp/product/B000S5Q9CA/ref=oh_o03_s00_i00_details
i've used it now 4 times, twice on a trip from south florida to orlando.
It charges the phone just as fast, if not faster than my home charger. On the way back, my phone was at 35%, within 2 hours it was back up to 100%. No GPS and a couple phone calls.
on the way up, GPS on and it never dropped below 97%.
so i can tell you without any doubt what-so-ever that this charger works perfectly with the galaxy nexus and will charge it with Navigation and phone calls running.

I bought a charger very similar to this one and it works great in my car. I make sure any charger I get is rated 5V DC at 1000mAh at least.

I have 2 USB 2.5A dongle chargers, one by Belkin and the other by Kingston. Both register as charging via "USB mode" and do not provide sufficient power while the phone is in use(loses charge usually). I also have that Motorola Rapid charger but the way the cable is designed it tugs on the USB port and comes loose often. I ended up just using the normal USB cable that comes with the phone and a 140W power inverter. Granted, it's not the most compact of devices, but it works well. I got it from Walmart for $20. Here's a link to it:
http://www.walmart.com/ip/Schumacher-XI14-Power-Inverter/15140199?findingMethod=rr
(and yes, using a power inverter will have the phone registering as "charging AC" and give a full proper charge.)

I'm using a Scoshe (sp?) dual USB port charger I picked up from Staples. It has a 1amp port and a 2.1amp port and I just use the micro usb cable the GNex came with

There was another thread, I think in the General that discussed all of this, what people came up with was the best combination if you want a dual port usb charger is to make sure you have a "charging only" USB cable. This cable will not make your phone think it is connected to a computer. You can tweek a data/charging cable to work but some people messed that up so it is probably worth just spending the $4 on a cable that works.
Here is my combination that works great. With this set up I can have on my navigation going with the screen on the whole time and stream Pandora over Bluetooth into my car and the battery still charges really quickly.
Dual USB Port with a 1 amp port and a 2.1 amp port (2.1 amp port is for tablets or power hungry devices - like the phone while navigating). http://www.amazon.com/gp/product/B0056VNVV8/ref=oh_o01_s00_i01_details
Charging Only USB cable:
http://www.amazon.com/gp/product/B003VYBCAY/ref=oh_o00_s00_i00_details
This combo has me as "Charging AC" whenever I am in the car and I still have a port open to charge another one of the 27 or so different electronic devices that seem to clutter my life!

Thanks for this. It's been driving me mad how car chargers and cables are so inconsistent. Pun intended.
Seriously, why can they come up with a standard and call it a day?
I have a had a few GPS/Pandora runs. Even while it says AC charging and my charger is rated for 1A, it drains the battery by 300-400ma.

[Q] USB Wall-Socket from ThinkGeek. Will it work with my GNex?

I apologize if this is a dumb question, but I'm not exactly an electrical engineer. I was looking at buying one of these for my room: http://www.thinkgeek.com/gadgets/travelpower/e81a/ and it says it outputs at 2 amps. i notice the stock Samsung charger is 1 amp. Will I be doing any harm to my phone by using the wall outlet vs. my stock charger? Or will it detect it as a USB charger, charging it at a slower rate?

Ya it'll be fine, it says UP TO 2.1amps.
Also it says it charges all mobile phones that accept USB power.

yes it will work. I have a few of these installed in my house. Your device will only pull the amount of amps that it needs. The voltage is what you have to look out for...

it will work, but it is not up to the 2011 nec code as it doesn't have tamper resistant shutters, I would recommend this instead.
http://www.amazon.com/Cooper-Wiring-Devices-TR7740W-K-Combination/dp/B007NC5GI4
It works the same, is up to the latest electrical code, is cheaper and will work with a standard wallplate.

Thanks for the input everyone, I think i'm gonna spring for one (may not be the Thinkgeek one though, as the one cade80 posted and a few other's I've found are cheaper) at some point, just to cut some clutter from my bedroom a bit.

Good eye on that, depending on your needs this may outweigh the being up to current electrical codes.

most third party charger will not charge you samsung smartphone at full power.
to charge at full power you must shortcut middle pins.
"will not charge" - not correct, your phone reduce it

So I went ahead and decided to not spring for the ThinkGeek Charger, and instead bought one of these: http://www.lowes.com/pd_369050-6337...&pl=1&currentURL=/pl__0__s?Ntt=usb&facetInfo= and just put it in a standard plug to test it to make sure it worked. Well I plugged it in and the first thing I noticed was the GNex was taking a while to recognize the plug. Finally it started Charging (USB Though) which was OK with me. Well last night I plugged it in via my Samsung Charger to a standard power strip because I hadn't gotten around to installing the RCA plate yet. Well I woke up this morning and it was on like 50% power and wasn't charging. So I was like WTF. So I brought it into work with me this morning, and now when I plug the stock Samsung charger with the stock samsung cable into the wall, no charge. I tried plugging it in to my computer, and it eventually makes connection with the computer (it's not instant like It used to be) and Android File Transfer starts, but says it can't connect to the phone. Then it charges for a few minutes, up about 1%, then stops charging. So my question is, when I plugged in my phone to the RCA charger last night, did it fry my phone? Or is my charge cable maybe bad now? I haven't tried another cable yet (everyone at work is an iPhone user and doesn't have a Micro-USB cable lying around) but I'm going to try that and hope it works. If it's not the cable, is it possible that the phone itself got damaged? If so, how could I go about removing root and wiping it to take it into the VZW store for replacement without USB to the computer?

Another new development. I plugged it into a Windows Box (I was using a Mac) and when I plug it in, it says "This Device can perform faster" and talks about plugging it into a USB 2.0 port. I'm using a 2009 Macbook Pro, it has USB 2.0. It won't mount the disk either. So i'm really beginning to wonder if the USB cable is fried.

Turns out it was a bad USB cable. Went to Best Buy and bought a generic cable and it now charges and hooks up to the computer just fine. My ADB doesn't seem to be working though for some reason, on Mac or PC...

Ok, everything is working now. ADB wasn't working because of a conflict with EasyTether on my Mac. Thanks everyone for the suggestions but I've decided to just stick with what I have now (power strip) and not deal with it.

[Q] Specific USB cables for S4?

Hello guys,
The reason I ask this question is because when I was trying to root my phone I was using a micro usb cable that I bought off of newegg and it only charged my phone.. I had to switch to the usb cable that came with the phone to actually let windows detect my phone.

The cable you bought was most likely a pin-shorted one that enables "fast charging". Any standard USB cable will work with the device. If you want a spare, get a BlackBerry OEM cable. For some reason, they're quite high-quality.
e: My old one's quite worn out. Just bought a new one.

But the weird thing is the cable works for my LG G2X. It doesn't work for my S4.

http://www.ebay.com/itm/6ft-Samsung.../140944620745?ssPageName=ADME:L:eek:C:US:3160
I ordered that cable and it came today... Plugged it in to my phone and it didn't detect it. It only charges.
Any of you other guys have that problem? I'm going to try the blackberry one that k0nane suggested.

I tried a blackberry cable at work and it didn't detect my phone. Went to my car and got my Nexus 7 cable and it worked fine for detecting phone + rooting. My HTC and 5 foot long generic cable has worked fine.
Connect directly to computer if you are currently connecting through a hub?

Yeah I've tried connecting through the back of the computer and it's a no go. Anyone else have any ideas? I just bought the blackberry cable and I hope it works.

I got my BB cable today, and while I can confirm that it works normally, it's a disappointment. Certainly nothing like the cables of old. If you need a cheap one, you're probably still better off with it, but the legend it ain't.

S9 Moisture Detected in Charger Port message, port is dry and clean, never been wet.

SO yeah, I've seen where people have had software issues causing this on the Note 8, and S8 models, is it a bug that crept into the S9 as well? The tech at the Sprint store verified the cleanliness and dryness of the port, thinks it's the port, and they won't have parts to fix it for probably a month or so. I REALLY don't want to send it in to be fixed, so I bought a couple wireless chargers.

Yeah, tried rebooting, wiped cache, power down all the way, multiple times. Tried plugging the cable in while booting. It looks to be charging while plugged in and powered down.
So, the message went away, and it would charge with 2 different chargers, normal speed, not fast charge. Would not work with a charger I have here at home. None are Samsung chargers, but all are QC 3.0, which will report as fast charging on the phone. Then today it charged fast in the truck, and the one at home works, but only slow speed.
I'm not going to stress over it as long as the fast wireless charging keeps working. The battery life is more than enough to get me through a day, and I'm ordering stuff to integrate wireless chargers into the vehicles.
Thanks for reading and trying to help!

I probably missed to ask before, but are you sure you are using the original cable, together with the original power charger?
As stressed by @DeadlySin9 the problem may be the cable. Try other cables.

Yeah, I had tried the original cord and charger. whatever it was effected the phone before even plugging it in. The message would be there in the notifications, then plugging the cable in would set off an "alarm" telling me to unplug it and let it dry.
A couple weeks later and it is working just fine, charging with pretty much any cord, and charger. Ugh. I hope it stays that way! LOL At least Sprint DID give me a pretty good discount on a 2 pack of wireless chargers, which is what I use most of the time, now.

Thumbs up!

So, I've had this problem with my new Galaxy s9 as well. Here's the specifics - this only happens IF the phone dies from running out of power. If I let the battery drain on accident, I plug in the device...new cord/charger, original cord/charger, doesn't matter...and it shows the charging symbol for just a second, and then warning there's moisture in the charging port. There's not... If I set the phone on top of a wireless charging pad for a few mins, it charges just fine.
All I have to do is get 3 - 4 % so I can power on the device and get to the home screen. If I can get to the home screen, I can plug the phone in with the cord/charger and no problems.
I just did a warranty replacement because this problem is real annoying. I don't let the phone run out of power often, but sometimes when I'm traveling for work or camping with scouts, it happens. So, before I sent my old phone back for the warranty swap, I let the new phone run out of power and then tried to plug it in. Same error!!

If anyone has this problem follow this trick. "connect the charger half to the charging port." that is it. works fine to me..
