Update: v.2! (half a penny)
Inspired by this video/OTG, pass to 0:47. Which I couldn't find one to purchase. This L design when plugged in is a bit smaller than a penny. No welding needed! Use (female USB for game controllers, mouse, ect). Designed with a case-on in mind.
======
You'll need 3 parts for hardware. Micro USB OTG, Micro SD reader, ofcourse Micro SD card and a software of your choice to run it. I don't root so I'm using Nexus Media Importer.
Be safe and wear gloves. You don't want to get hurt for this mod.
======
Step1: Cut in the middle of the left or right side of Micro USB OTG. Be careful, use glove on the hand to hold it down. (note: the OTG link that i provided is the exact one that I used to mod, but you can find the cheapest parts from Amazon or Ebay, ect.).
Step2: Peel out the inner part of the OTG.
Step3: Cut the part closer to the Micro USB completely off (with wires still intact). Carefully peel the wires to the far end of the USB female. Then cut the rest of the plastic off like in the picture.
Step4: Turn the Micro USB end to make a L shape like in the picture. I used glue gun to clued it together. You can use electrical tape if you like. Enjoy!
**I'm not holding reliable for any injuries or broken parts from this mod, do it at your own risk**
This is the original size of the device when it's plugged in, it's about 3 size of a penny in length.
Step1-3
aaaa
Step4
====================================================================================
Version 2 still retained female USB for mouse and game controller or a case in mind.
==========
You'll required soldering, glue gun or electrical tape. (note: this version is a challenge to make. If you think you can solder the wires into the small spaces on micro USB's bins then proceed or you can make version 1 which required no soldering)
==========
Step1: Strip micro USB and female USB completely. (any spare female USB from old devices will do. Make sure you have the right micro USB end like in the diagram if you decided to get a spare)
Step2: Measure the wires as needed from micro USB to female USB. Then pre-cut the outer layer of the wires so you can bend at 90 degree angle with ease when wiring the wire along the sides. (careful don't cut the wires inside). Next, strip a few millimeter from both ends of the 4 wires.
Step3: I suggest to lay the 4 wires on top; along the micro USB and solder it in the pins. (though I didn't realized this obstruction was a big deal until it resulted in a bump on my model when wiring it downward). Curve your stripped end of the wires for easy soldering. A trick I used to solder the wires to micro USB is putting a thin foil paper in between 2 pins. After you're done, remove it and repeat until you're done.
Step4: Lay your micro USB on top of the solder point of the female USB at 90 degree to shape the L. (make sure no metal part of the micro USB touches the female USB sholdering point. You can lay it on top of the female USB but it will add a few millimeter thickness). Follow the diagram to solder all wires to the female USB.
Step3
aaaa
v.2 when plugged in it's half a size of a penny. You're seeing USB plugged into the OTG with microSD inside.

Thanks for the "how-to", Capt.PP.
Thank you, with your suggestion, and pictures, I can also put the USB behind the tablet as a U, and maybe make it smaller without the USB (male and female) only the card reader
I like it!
It's quite similer to the one I made:

Cool, Aleemz, how did you make yours?
If you want to make it smaller and you are going to the trouble of handsoldering and hot glueing, you can just get the Micro USB Plug
http://www.digikey.com/scripts/dksearch/dksus.dll?vendor=0&keywords=609-4051
Remove the USB shield, solder the Plug Directly to the USB traces, and Hot glue around it, you can reduce the size by half (maybe even more)

I think that, if I were to make one of these, I would make it in a "T" shape after removing the male and female USB connection, with the opening for the micro sd card facing in whatever direction seems best, so long as the card and its holder are parralel to the side of the device that the micro USB port is on. That way the whole thing would stick out no more than 5/16th's to 3/8th's of an inch when plugged in to the micro USB port and the protruding top cross part of the "T", that being the part with the micro sd card, would act as a grip for removing the device from the port.
(If that makes sense.)

You also have to look at cost effective here. The parts that was used only cost $1 for OTG, 30 cents for small USB, minus the Micro SD card. Though i'm not recommending 30 cents for small USB (they didn't clued it and harder to get the Micro SD card out) compared to the one above I recommend in the link.
The L design flushed with the screen surface and thinner compared to the bottom surface or a device as a whole. It prevented from accidentally snag the OTG when swyping on the screen. It's very easy to plug or unplug since you have a penny side in width (when you DIY you can add grips) and 2 penny side in length if you have a big thumb.
The T design, if i understand you correctly, you want to stick out above the screen a bit so you have grips to pull it out? I can ensure you the L shape have no problem of unplugging. Though you eliminated the female/male USB but it still lay hidden on the edge bottom of your device. Instead of buying new parts (may cost more) you can use the OTG I recommended to strip out all the white plastic to make it even smaller as you want to reduce in length when laying on the edge bottom. Cheer.

Where did you get your inspiration. Great minds think alike.
Cool I'll tried one
I am going to just try soldering/wiring a micro-usb jack directly to a 32GB flash chip from a torn apart flash drive. Still waiting for parts to come in the mail. Here is a pretty good wiring guide that should help anyone looking to do the same.
http://tech2.in.com/how-to/accessories/how-to-make-your-own-usb-otg-cable-for-an-android-smartphone/319982
You could probably do the same thing with a micro-sd hard adapter.
Also another idea : Build it directly into a case, much like this Galaxy Nexus Battery Case

Hey, I'm not very electronically inclined. Could I pay someone to make and ship me one of those "plug" OTGs? I have a 3" cable one, but I LOVE that little plug.
I'd even order one from Hong Kong and wait for it
Thanks
This one looks pretty good, for those who want it as un-obstructive as possible. I ordered one but will have to wait for it to see if it works fine.

Oh snap, they read my mind. I finished v.2 of Micro USB OTG to USB Adapter but very similar to this last week, but since I sold my phone I couldn't take pictures and post DIY v.2. From the look of this, it seem my v.2 is even smaller.

I finally received my spare Tab usb cable and a few microUSB SMD sockets and have successfully hacked them together to make a very portable adapter so that all of my existing microUSB cables work on the Tab as well. No more having to carry a different cable with me!
Nice work. How did you mount the female micro so neatly?
Sent from my SGH-T849 using XDA App
A video of it functioning would be awesome. I am interested in making this as well. I actually want to create a full USB adapter. I know there is a schematic of the cable and what each one does. Its just a matter of wiring it up right. Perhaps you can make a how-to? what if you plug a USB thumb drive using a USB to micro USB adapter. Would that work?
From the Tab.
www.twitter.com/ayman07
I don't know if it would do anything with a thumb drive or anything else that requires a host port. For a microUSB socket, there are 5 pins, of which 1 is unused when you wire it to a regular usb dock connector like this one. I haven't looked at the pinout posted, but it's possible that 5th connection is to toggle/enable host mode on the Tab. If I get a chance I'll plug in an external drive and see what happens.
As to how I shoehorned the micro socket into the dock port connector, it just required an X-acto knife and some super glue. Soldering on those tiny smd pins is a pain, so if I make another, I'll etch a small pcb and mount it that way.
Great work! Do you have any pictures of the inside of the adapter?
Unfortunately no. I will take pics of the inside of my next project, which is to make a dock connector adapter that'll break out into a microUSB port alongside of a miniHDMI (kind of how Samsung should've done it to begin with). I'll definitely snap some pics then, and post up the Eagle files if anyone's interested.
EDIT: Looking at the pinout thread, it looks like the HDMI dock has all sorts of stuff in there that I had assumed were inside the Tab. I'll probably make another microUSB adapter so I can prototype the pcbs.
EDIT2: For USB On-The-Go, it looks like the unused pin 4 (ID) just needs to be grounded to pin 5. I'll test that too.
Wow, this looks great. Have you thought about making a few spares and offering them up for sale? I would definitely be interested. Let me know
I'm currently trying to track down a supplier of the 30-pin connectors. Seems a very daunting task at this point, since I can't speak Chinese, and the majority of the component suppliers do. It wouldn't be cost-effective to purchase full usb cables with the connectors just to harvest the connector off of them. Also, to even test the OTG functionality would require a dock connector with all the pins (or at least pin 13 + the usb ones); most of the usb charging/sync cables only have 7 of the 30 pins. The only connector I know of that has pin 13 is from the HDMI dock, and that's an expensive way to test.
So once these connectors are more readily available, I'll look into making a batch.
I thought I saw a thread about this a long time ago but search as I might I can't find it again. Anyway, I was wondering if anyone had a link to an OTG cable that angles...well...down if the N7 is in landscape mode with the camera on the left side? I've ordered 3 and they all angle up which really doesn't work well in a case or anything since the "hinged" side is generally on the left.
Hopefully this makes sense. LOL
Alternatively, does anyone have a link where you can buy the male MicroUSB connector? I've tried Amazon, Monoprice, and even Radio Shack (that's desperate) and can't seem to locate this part.
Thanks!
here is the one i have.. You must also get a micro a usb to a usb female adapter.. Not sure i ordered from the same company but i know it was over seas.. i bough them as a set one up angle one down angle..
that is term.. down angle micro a usb cable... Be careful that you do not end up with a usb mini which is a b type connector..
micro a down . look close at the picture so the flat part of the connector port is to the top . which is the back side of the plug. ok that all sounds confusing but . well here is the link..
http://www.ebay.com/sch/i.html?_sacat=0&_from=R40&_kw=down+angle+micro+usb+cable
One more thing.. Make sure its a 5 pin if its not usb. just slit the wire carefully and cross pin 4 and 5 will turn it into otg. Or use a otg connector at the end... This is what i did.I pluged my otg connector into this.. and its stil flat to the back of device..

I don't think the down angle would work. Basically, when plugged in, I want it to angle to the left side of the device. It seems most angle to the right. Then I could actually put the cable and flash drive inside the case and out of the way so it would be more "permanent" when I'm out and about.
I'm all for angled cables, but the down angle one doesn't excite me. I was much happier with this style cable:
http://www.ebay.com/itm/Left-angled...=US_Video_Cables_Adapters&hash=item23243a6e6a
This isn't an OTG cable, but I use this in my car so the cable is tucked away neater. I had the same confusion when trying to figure out if I needed left or right. I ended up buying both because my phone is one way and the Nexus 7 is the other, so I knew that was a win/win. Prior to realizing that I just hit up Google image search and looked for a larger picture of each one... then tried to envision how it would plug in accordingly.
Hmmm. Mine faces "down" when the camera is on the right side. The smart case folded behind from the top.
I got mine from Amazon for my Galaxy Nexus a while ago.
Those listed above from eBay are wrong. Those would actually attach front to back (screen to back housing) and would be awkward IMO.
Mine attaches and the cable slides down the lining of the trim. I got it from Amazon.
Here is what you want. Take note of the micro USB port:

After a while of trying to solder to the micro b tiny contacts to make a cable, I ended up doing the same thing as you. Then came here to share, to find your post haha.
Except I attached mine to a usb cable to a usb charger, just put a piece of thick paper to not short on anything and tighten the screws down with the wire under the washers:
I have been looking for a way to expand storage on my Note 5. It would seem quite easy to fabricate a short extension cable. One end would be a low-profile right-angle micro-usb connector such as those used in the stand-alone NFC charging coils. A short ribbon cable could then wrap around the back of the phone, terminating in a micro-sd socket. It would be a simple matter to install this and tuck it into the back such that a skin could hold it securely against the back of the phone.
I am surprised that I cannot find such a device anywhere. It would not be difficult to build if one could find the parts, but I have been unable to locate a source for the micro-sd connector. Note that those attached to NFC coils only have power pins, so they are not usable.
Does anyone have any suggestions?
I like your idea...alot!

I want something with zero profile. I am frankly amazed that this product does not exist.
Agreed. Submit a patent . So obviously missing in the market!
I wouldn't even consider "hacking" your own flex cable unless you are very skilled at working with flex print. It can be quite challenging. But, I agree with this topic here, a nice flat cable to wrap around with a microsd socket that could be tucked under any medium size case would be great. Even better if cases came WITH the option for a microsd card seeing as how Samsung decided it was wise to give the S6 128gb and the Note5 64gb...
Whenever I plug my phone into my computer and wiggle it around a bit it disconnects. It's a brand new cable too. I'm assuming I need to have my charging port replaced?
Never assume. Check to see if it happens with a different cable first. If it repeats with the second cable, then take the phone in for servicing.
It would not be worth to replace the charging port. It is time to get a new phone, isn't it?
It would be far less expensive to replace the port than to replace the device. Besides, without actually taking apart the N6, we don't exactly know what's going on. The connector could truly be damaged, or it could be a simple issue of the connector losing connection with the motherboard due to a bad solder joing; something that some skill with a soldering iron could resolve.

Indeed, it is that time. The only phones that meet my needs (fast wireless charging, USB 3.1, Bluetooth 5.0, microSD, etc) are the s8s so I'm going to wait for the Note 8. The Essential PH-1 is also on the radar but I really don't want to go any smaller than a 6" display.

Have you tried to remove any lint with a toothpick or similar tool? Doesn't cost anything to try a thorough cleaning before anything else...
You could also use a magnetic micro USB adapter, people say they fit very tight in the plug

I'm pretty sure the port was just dirty. I blew in it (like the old Nintendo games) and now it stays connected while wiggling the cable around rather forcefully.
