Hey guys, so I noticed this the other day and I was just wondering if anyone has noticed the same problem with their USB cord that charges the nexus 7. It's still charging my nexus 7 perfectly fine and it functions normally, its just loose.
I don't have that problem with my USB cable. But when I plug in the cable, the plug seems to be at a bit of an angle. It's as though the micro USB port was put in the N7 a little bit twisted or something.

ive noticed that too, that could be the result of the longer side being put in on the top side instead of the bottom? I dunno, all i know is that ive never had this happen before on any other usb cable
I got an OTG cable off ebay and it said it was good for nexus7.
PROBLEM IS...
When i plug it in nexus7 Instantly, totally shuts off.
Will NOT turn back on no matter how much i push POWER....
UNLESS i plug my nexus 7 back into it's wall charger.
Anyone ever have this problem with an OTG cable?
Are you plugging in just the cable, or are you connecting something to it? I had my N7 reboot when I was screwing with USB power and a hard drive.
Hi. First I tried it with nothing at all. I thought it killed my N7.
Than I tried it with it plugged into my six axis gamepad.
Same thing.
No matter how much I would push the power button it wouldn't go on.
Plug in my Ac adapter and it boots.
I'm using stock, unrooted.
Any setting that can cause this?
Im thinking some wires that are not supposed to be touching inside the connector are shorted.
EBay merchandise is always questionable quality. Yours is shorted - send it back to the seller. He will sell it to the next guy in line...

...or get a new one, it probably cost less then shipping.
Check out dx.com, I got 2 adapters and one cable (all OTG) from there, and everything works.
Thank you. I'll get another. I'll let you know how it goes.
Oh, I have a question.
Is there an otg cable that allows charging of N7 while using with a gamepad?

With stock kernel OTG charging will not work.
If your Nexus is rooted, you can flash custom kernel (Timur's latest mobile kernel from http://rootzwiki.com/topic/37755-timurs-kernel-usb-host-power-management-usb-audio/). The one from faux123 (013) will also work, but charging mode must be enabled/disabled via script. In Timur's kernel it's automatic.
Then something like this will work (I use the first one, but ordered the second now):

Hope it helps.
OK. .I guess i will need to Root than. The reason i wanted to use the OTG cable was to not Root. But since i can't charge while playing. (without rooting anyway)
I'll root and than i'll be able to run the controller off of bluetooth and charge.
Thank you.

does anyone know if a mouse using an otg cable will work in recovery mode. cracked my screen looking for a way to flash new roms but not dont want to restart my tab because im afraid i wont be able to get out of recovery. im running m-kernel 32a with multiboot.
I don't know but if you start a new thread your bound to get way more hits and maybe someone who knows would see it.
The CABLE was the culprit. Got a new one. It works. Thanks.
bringing this one back from the dead. i have a KNOWN GOOD usb otg adapter that works flawlessly in my nexus 5 but has the exact same symptoms as the OP, it powers fully off and wont turn back on without a wall charger or battery pull.
sincei know its not the adapter what other options do we have
Hi,
I've juste updated my Nexus 4 to Android 4.3 and I've got a strange problem.
I've got an USB hub that was working perfectly to charge my phone (a little bit slower than a computer USB port or the official charger but still quick).
But now it don't charge. When I plug it the phone doesn't charge but when I remove the cable my Nexus play the sound like when you remove your charger when battery is slow. Anyone has an idea?
Charges fine here.
Did you try another charger?

Yes with the wall charger, a computer USB port or my Samsung power bank battery it works fine but not with my USB hub anymore.
And my girlfriend Nexus 4 is still in Android 4.2 and it charge normally.
Like if Android 4.3 need more juice than 4.2. Really strange.
Make sure that you are using the stock charger, sounds like that Android 4.3 needs more power.

Is it possible to be caused by some old files or settings from Faux Kernel from 4.2.2?

Same here. Since 4.3 not charging on usb port when powered on, but charging perfectly when off.
I am still at work and can only charge via my computers usb port, but I expect it to charge normally with the provided charger at home.
Totally stock rom, so no SuperSU or anything to interfere.

Mine is charging fine after the 4.3 update but I'm running completely stock unrooted.
I'm wirelessly charging using my Nokia DT900 charger as I'm typing this.
Also charges perfectly when connected by cable.
Noticed that I now get a sound alert when the phone is fully charged. I never ever got that before.

Get another charger or get a different kernel. Google likely added this to let phones charge more efficiently and prevent your charger from blowing up (the result of it drawing too much current).

I currently have an issue charging when hooked to a PC, I was able to disable the "media device" option and then it started charging once I unplugged and replugged in the USB.
Steps to duplicate:
1) Connect phone to PC via USB with Connect as "Media device (MTP)" checked (Settings -> Storage -> Menu -> USB computer connection)
2) See that the phone is not charging.
3) Uncheck "Media device (MTP)"
4) Unplug and replug in USB cable
5) See that the phone is now charging.
6) Re-check "Media device (MTP)"
7) See that phone immediately stops charging.
Same here. 100% stock. No longer charges from wall at night (phone turned off).At 51% in the morning.
I'll try to do a full wipe.

I've got exactly the same problem. Updated my Nexus 4 to 4.3 yesterday. Now at work, I cannot use the USB charger from my work PC any more. Tried with different cables, same result. When I charge my Nexus 7 running 4.2 on the same USB port at the work PC it still works.
Can the Android Kernel somehow measure the amount of power delivered by the USB port and set the icon to 'not-charging'?
When I try a seperate USB charger (delivering 1.2A) it works again.

If someone as some free time and if it's possible (I don't know) can he try to flash the 4.2 stock kernel on the 4.3 ROM. It could answer your question.
After full reflash and wipe still wont load from wall charger when off. Have to try not turning it off at night because it seems to charge if powered on.

Seems that if i disable MTP the phone charges even when off.
Initially my phone started to charge slow since a week with the original charger and cable came with N4 in the box. I googled and got to check in the battery settings as if it shows AC or USB. Its showing USB and charging quite slow. I flashed yesterday factory image after deleting everything but still it shows as USB.
One more thing, when i connect the charger it shows AC and after a few seconds it says USB and sticks to it.
After connecting the charger it acts as the charger is powered on and off 3-4 times whereas i dont turn the power off/on.
Any help.

Happens to me as well. I even got a new USB cable from Flipkart and tried with other chargers. Same thing happens. I googled enough for this and find no feasible solutions.
It seems to be a hardware issue. but the weird things is it initially recognizes as AC but then after few seconds change to USB.
Further, after pinning the cable, phone reacts as the power is on-off-on-off 3-4 times.
Please help.

It might be a defective cable. I had the same thing happen to me (oem cable and charger), but changing the cable solved it for me. Pretty poor build quality if you ask me

i can confirm that it is the cable. just go buy a new one but have in mind that you need a quality cable. the reason is that the usb 2 standard outputs about 1 amp, so most cable is designed with that in mind. the nexus 4 charger output is 1.2 amp so if the charger cannot output 1.2 amp it outputs lower amp thus the connection with the charger is recognized as usb. if you go and buy a quality cable then you will have no problems. i just use the cable of my old phone (optimus black ) and it works like a charm. another cable that i have make the usb thingy.
the lg cable of nexus 4 and all the new lg's is ****. it break down very easily. a friend of mine bought an lg g pad 8.3 and the cable died the 4 time that he used it!!!
P.S. when i say quality cable i don't mean a 30 euroes or dollars cable. i mean a cable by a known brand and not an ebay 1 euro cable. that didn't worked for me. if i knew a brand of cable that worked i would but i use an old lg cable
hope i helped

This happens to me as well but I don't think it is the cable. When mine started charging slowly & on USB with the official one I bought one that was made by Amazon which was fine for a while but then it changed to USB charging
If you have a custom kernel that supports forcing AC charging, give that a try. I think the latest Hells Core/Doctor kernels offer that feature. Unless this feature is on, my phone thinks my car charger is a USB charger. It might be, I'm not sure, but I know that the kernel has a feature to override this recognition and extract the full average from the adapter (in my case, 1A).
I bought the nexus charger off of Google.com and now it always shows charging (AC) and it charge at a good speed

I've seen this question pop up a while ago but it doesn't appear to have been solved. Someone mentioned that the KTManta kernal might have solved this but I couldn't find that answered anywhere in that thread (here). I am using the USB OTG cable to control an IR Droid USB transmitter in a permanent kiosk installation and I need the pogo connector to supply power so this can run 24/7.
Any help is much appreciated!
UPDATE:
Wooo!!! Just thought I'd give the kernel a shot and see what happens... it works! I have a separate USB voltage meter that confirms, as well as seeing the battery % increase while being used, and my IR Droid is also working.
Just install the above mentioned kernel, plug in the USB Y OTG cable into tablet, external power supply to the male USB end of Y adapter, and external device (mine being the IR Droid device) to female USB end. Plug second power supply (I used the 2.4a (12w) iPad charger) into pogo connector. Win.
Ktoonsez, your next few beers are on me, good sir!!
UPDATE: The latest KTManta kernel (04-06-2014) breaks root (SuperSU) with the stock rom. In my case that is v4.4.4 so I've had to revert to my nandroid backup. The issue has been known for a long while but it seems the dev is prioritizing his kernel on other devices. Obviously this means I'll not be testing any time soon.
Interesting, I've wanted this solution for a long time as I use an USB Ethernet adapter from a room with poor WiFi reception. I'll see if it makes any difference if the OTG USB device is attached to a powered USB hub or not and report back.

Oh man, I wish I knew about it breaking root before installing!! I was wondering why it was saying I wasn't rooted... Is there a way to fix root while on this kernel?
I'm having some issues with the tablets now that I didn't have before - the most basic seems that it won't boot (won't even start the Google logo) if I have both OTG device and Pogo connected at same time when the tablet is off. I did solder my own right angle tip onto the OTG Y cable though, so I may have messed something up... I'm going to be doing some more testing over the next couple days and I'll keep this up to date.
"Is there a way to fix root while on this kernel?"
The root issue with KTManta's latest release is specifically with the stock ROM from what I've read in the N10 KTManta thread. So it would seem that installing a non-stock ROM then installing the KTManta kernel would be the only way to get this kernel and root. I'm unwilling to do that for this single feature. There were comments that root was still working on an older KTManta release which if I can remember is from Dec 2013. I've no idea if that release has the charging features you see with the latest release.
If you go the custom ROM route then read the KTManta thread to find out which custom ROM's are working. Don't quote me but I thought the OMNI ROM was one that worked, please confirm that for yourself.
From my experience stock with the XPosed framework is more stable than any custom ROM and I've tried many.

So there were a few other issues that I found out while testing...
If you have USB plugged in, then reboot, the tablet freezes while trying to boot. It doesn't even get to the loading screen.
It seems a bit buggy as to when it wants to work and when it doesn't, and all the while the tablet says that it's charging so it is hard to test, but I was using a USB volt meter to see if the pogo was actually taking power or not.
The next thing I want to test is using a powered USB hub, instead of a Y cable. Has anybody done this successfully? Does it need the modified kernel? Does it ACTUALLY charge, or just say that it is?

I use a powered hub to access an Ethernet adapter while concurrently having the pogo plug attached. The result is that the tablet drains slower as the Ethernet adapter is drawing power from USB Hub rather than the tablet. The tablet does not get charged in anyway despite the false charging icon indicator. This is why your post was so interesting to me until I discovered that root was lost. I can live the charging and OTG limitations but I can't loose root.

I tried this the same way as SupremeTaco described.
My nexus 10 runs the latest Omnirom 4.4.4 with latest KTManta kernel.
I plugged in the OTG Y Cable, which was connected to a charger and a usb SD-card reader. Then I plugged in the Pogo charger and to my surprise, the Nexus 10 charges yay! (I saw the battery percentage increase as I was using device with screen on)
SupremeTaco thank you for this great tip, I have been looking for a solution for a long time. I can now charge my Nexus 10 16GB while using a Meenova reader with 64GB microSD card - which is extremely useful :good: :good:

Sorry for the slow response,
I did some testing with both KTManta kernel and the stock Omnirom kernel and indeed booting with USB plugged in does not work. The culprit seems to be the OTG Y-Cable and specifically the power supply part. If you disconnect power from the Y cable but leave everything else plugged into the tablet, the tablet will boot. Perhaps you could have a power switch for the Y-cable and switch it off only when booting?
Also, I have discovered that Pogo charging with Y-cable also works on stock Omnirom kernel. So it seems that the kernel does not affect the charging capability with this setup in anyway, so we are not limited to using KTManta. However the booting issue does not seem to be a kernel-related problem.
Edit: I also confirmed charging in this way works with franco kernel r16 (so it will probably work with all other franco kernels and any other custom kernel)
