MHL V1 may be true but the problem is something Samsung did in software or firmware. it worked fine on the S3 on 4.1.1,

the update to 4.1.2 broke it and it has not been found out how to change it back.

reflashing back to 4.1.1 enables it again.

http://dx.com/p/mhl-to-hdmi-otg-car...s3-s4-n7100-n5100-p3200-black-32gb-max-242489 This looks very promising for the money. HDMI, usb and a card reader all in one dock via mhl. I'm sure the usb and card reader is just off a hub but its a nice compact dock.
[Galaxy S III Accessories] voyager20021:
I don't think hdmi and otg work at the same time. So no smart dock there.

On the other hand, if it's mhl 1.0 we have how would hdmi port work w/o charging? Both 5 and 11 pin mhl cables need charger connected to usb port to work.
[Galaxy S III Accessories] its.mahmud:
I think thats what we all was looking for. ......
[Galaxy S III Accessories] zanzee:
Mhl 1.0 can USB otg and HDMI at the same time. The note2 dock proves this.
[Galaxy S III Accessories] voyager20021:
You didn't understand. SGS smart dock is using original charger in order to have hdmi out. 11 and 5 pin mhl cables are using the charger so they could work. From what i know only mhl 2.0 works w/o charging at the same time (SGS4). I see now this hub also has additional micro usb port for 5v charging, hence the micro usb to usb cable it comes with. So indeed this should work unless sammy blocked attempts like this from rom (mhl and otg working at the same time). I read somewhere mhl code from android is proprietary. So, unless someone tries it and reports we won't know.
[Galaxy S III Accessories] SchecterRocker:
I risked $24 on a dock with HDMI and 2 USB OTG ports. It does not have a 3rd USB port or an audio jack like the Samsung Multimedia dock does. I asked the seller if HDMI out and USB OTG are possible at the same time, and the seller claims this works.

Guess I'll find out. I'll report back when I receive the dock in case anyone is interested in this potential solution.

I don't think I'm allowed to post links, so here's the info. Search the product description in Google; it's the first link.

eBay Product Description: Smart Dock MHL HDMI OTG Docking Station Charger Cradle For Samsung Galaxy S3 S4

eBay seller: Firstmatch
[Galaxy S III Accessories] SchecterRocker:
I am quite happy to report that this $24 dock functions almost exactly as I expected. I have only seen videos of the Samsung Multimedia dock, but from what I can tell this off-brand dock works nearly the same.

However, there are a few points worth mentioning. There is ever-so-slight, but perceptible HDMI lag. (My standalone MHL adapter exhibits this behavior, too.) Mice and keyboards are definitely usable, but you can tell the lag is there. I have a few hypotheses: 1. Perhaps the dock indeed lags some. 2. Perhaps my ROM/Kernel/whatever is a part of it. 3. Perhaps a bit of both.

Also, when a USB mouse is plugged in, HDMI output auto-rotates to landscape, the phone screen turns off, and roughly ~1/2s of HDMI lag occurs (presumably due to a software bug that occurs when a USB mouse is used). Many threads say this happens with the official Samsung dock also. This issue does not occur with ShareKM (due to the nature of the app), and others report that Bluetooth mice do not suffer the 1/2s of lag.

If anyone knows of a solution to the HDMI lag and USB mouse lag issues, I'd love to hear them. I'll do my best to respond to questions about the dock if anyone has them.

Finally, as a disclaimer, I never meant to undermine the awesome work going on in this thread by posting a pre-built solution. I personally love hacking together my own equipment. However, I thought others might be interested if the homemade solution did not work out.

You're using a note 2? That doesn't count! This was for gs3 that smart dock no longer works. Do you have a friend with a gs3 you can try it with?
[Galaxy S III Accessories] SchecterRocker:
I realize this is the S3 forum, but I posted here for a few reasons. 1. The dock is advertized to work with the S3. 2. The Note 2 and S3 (and S4) all use 11 pin USB connectors, so I thought this information may help S3 users. 3. There is a distinct lack of interest in cheaper dock solutions on the Note 2 forums.

As soon as I can get a hold of a buddy with an S3, I'll try it out and let you know how it goes. I can't promise how soon that will be, though.
[Galaxy S III Accessories] athlonxp2300:
Don't get me wrong I appreciate the info. S3 used to work until samsung broke smart dock mode with the 4.1.2 update. If you do get a chance to test it with a friends s3 please also get the rom and kernel versions. Thanks again.

[Galaxy S III Accessories] 01jacksonb.:
Apologies for another Note 2 Related post, however I tried to make on of these adapters back in January, and after multiple tries, and failures I gave up on making it, and bought a smart Dock to see how it worked, but due to multiple postage problems I still don't have a smart dock.

I was trying to design it for the Note 2, which I believe used the same wiring as the S3 4.1.1, can somebody please check over my pin-out to see if it is correct? as I never managed to make it work successfully.

Smart dock pins? (plug end):

Pin 1 - Vcc

Pin 2 - USB - (Slave)

Pin 3 - USB + (Slave)

Pin 4 - ID/Sense (connect to Gnd with 40.2K Ohm)

Pin 5 - Gnd

Pin 6 - ? (Audio/USB host?)

Pin 7 - ? (Audio/USB host?)

Pin 8 - DP (MHL +)

Pin 9 - DN (MHL -)

Pin 10 - MHL ID (connected to ID Pin of MHL Adapter)

Pin 11 - Gnd

I apologize for the mis-placed post, but I need some help, and nothing seems to be happening over on the Note 2 thread.

The link for Ebay is unreachable from Canada... (ebay restriction). Can you confirm that your Docking is this one:

Patuoxun Smart Dock MHL HDMI OTG Docking Station Charger Cradle for Samsung Galaxy S3 i9300 S4 i9500 Note 2 N7100

Link to a amazon:

http://www.amazon.com/Patuoxun-Docking-Station-Charger-Samsung/dp/B00EWH1VZ0

If it's the exact same, Do you think this one is 24 Frames per second or 60 Frames per second? You can easily see that, if it's smooth it's 60, if you see your cellphone frame rate slower than normal when connected, it's 24 FPS.

only MHL 2.0 can provide 60 FPS.

Thanks!

Cedric
[Galaxy S III Accessories] SchecterRocker:
My dock is visibly identical to the dock in the Amazon link you posted. While there are no part numbers on my dock or its packaging, I am 99.999999% sure this is the same one.

From my unscientific guesstimate, the dock runs roughly at 30fps. It I am reasonably certain it does not approach 60fps (based on my experience looking at the Fraps fps counter while running games). See my earlier post for details, but my AT&T Note 2 suffers lag and probably 10fps when a USB mouse is plugged in.

For my everyday use (Netflix, light computing, web browsing) it does a great job. However, I haven't tried gaming yet with it (I need to try my modified OG Xbox S USB controller with USB/BT Joystick Center) and I don't know yet if it gets my gaming seal of approval. Either way, I don't think gaming would be ideal (probably good enough for me though).

However, this leads me to my next point:

I tried my buddy's AT&T S3 with the dock and it worked flawlessly. It didn't even suffer the lag that my Note 2 does when I plug in a USB mouse. Overall and unscientifically, it felt like the S3 held a constant 30+ fps and performance was better than my Note 2.

I didn't want to mention this yet because I forgot to ask what version he was running, but I do know that it was stock and unrooted. Potentially not updated to the latest version either. I'll report back once I can find out.

Finally, just some interesting tidbits for tinkerers:

1. An audible click occurs a fraction of a second after power is applied to the dock (phone docked or undocked).

2. When the phone is docked and power is applied, an audible click is heard 2 seconds after an HDMI cable is plugged in.

Both noises sound like a mechanical relay is closing.

Perhaps this is interesting to anyone building their own dock.

Anyone want to try this with CyanogenMod CM11 since this commit just happened?

http://review.cyanogenmod.org/#/c/56012/

It should be available on the 12/20 nightly.
[Galaxy S III Accessories] athlonxp2300:
On my T999, I installed s3rx V3 (android 4.3) with md5 bootloader, mjc modem, and mj2 att insecure kernel .

To my surprise the smart dock mode works again with my home made dock cable! It turns off the phone screen but displays to hdmi and has keyboard and mouse working too.
[Galaxy S III Accessories] Telemachus:
I simply want a cable that will charge my GS4/Note2 and allow USB-OTG at the same time.

With my Verizon GS3, the bootloader (I assume) does it by default. All I have to do is supply power to the GND and VCC of the USB-OTG cable and it charges just fine.

So I followed the ideas of this thread, and put a 40.2k resister (series of them together from RS, was more like 40.5k) between sense and ground, and sure enough it will throw the Note2 and GS4 into "Dock Mode."

However, when I attach a thumb drive, it doesn't see it.

I didn't have a mouse or keyboard with me to test those out.

Can you all see mass storage drives with your DIY cables when in Dock Mode?
[Galaxy S III Accessories] athlonxp2300:
I can with my s3 and my home made dock cable. Unplug mouse plugged in usb thumb drive. Screen changed to "my files" showing drive contents.
[Galaxy S III Accessories] Telemachus:
Strangest thing. I rebuilt the cable using another cable and a potentiometer. Dialed it into to exactly 40.2k.

I am NOT using MHL, I just want USB-OTG and Charging.

The Note 2 on 4.1.2 goes into Dock mode, and charges. However, nothing is detected on the USB. I have tried it with the D+ and D- disconnected from the wall adapter as well, still nothing.

I also dialed the pot up to 64.9 and it charges, but no dock mode. I don't know if 4.1.2 supports audiodock.

I'll try again tomorrow on my wive's GS4.
[Galaxy S III Accessories] Telemachus:
Tried my ghetto cable on GS4.running 4.2.2.

64.9K resistor puts in into dock mode using any one of 2 amp, 1 amp or 500 mah wall chargers. However, nothing shows up on the USB port unless I plug it into the laptop USB (with the laptop cover closed).

My guess is it is either dependent on a low amperage, or the D+ D- Signals are bridged on the wall chargers.

When I plug into the laptop, I now get keyboard/mouse to work.

However, plugging in a USB thumb drive gives nothing.

For those of you using AUDIODOCK mode, does a thumb drive work for you? What power source are you using?

Thanks!
[Galaxy S III Accessories] athlonxp2300:
I know you have said you don't want mhl but this mod cable uses the mhl adapter to supply power.

When using the 11 pin to 5 pin mhl adapter to do this mod, the usb otg cable is one connection and mhl 5 pin is the other. If you don't want to use a mhl adapter to run the power through, you would probably need to use a 5 pin usb cable and disconnect the data wires and connect it to the charger. The problem is you will probably sense usb charge mode instead of ac power charge mode. It will be slow but at least the data wires won't be shorted.
[Galaxy S III Accessories] Telemachus:
well, 5v is 5 volts right? I kind of figured whether power is coming from mh l, or from another source, it wouldn't matter. can you all use mass storage drive with your devices?
[Galaxy S III Accessories] athlonxp2300:
I ran some tests for you. With my doc cable I can connect a usb thumb drive to the usb part and a charger to the mhl part and it works. Charging and access to usb.

I'm running s3rx 4.3 rom on my i747 I can give more details about my exact setup but I will say dock mode didn't work on 4.1.2 kernels. it worked on 4.1.1 and now on 4.3. I did not update my bootloader to 4.3! Just rom, and modem.
[Galaxy S III Accessories] Telemachus:
thank you, I just up to my note 2 to 4.3.

I can get Audio dock which is using 64.9 kilohms, or the regular 40.2 kohm dock to turn on. However, when supplying power through the ground and VCC lines, thumb drives will not work. A mouse will.

I would imagine it has something to do with MHL component missing, although how it senses that, I sure don't know.

does it work if you do not plug the MHL into the HDMI, but just a regular power cable into the wall socket?
[Galaxy S III Accessories] athlonxp2300:
My cable is built using an 11 pin to 5 pin mhl adapter very similar to the first picture in this thread. It is wired the same as the first picture. That leaves me with 3 connectors.

11 pin into the phone,

usb otg (for mouse keyboard or usb drives),

and 5pin mhl.

I can plug 11 pin into phone, usb drive into usb otg, and wall charger into 5 pin mhl connector and have charging and usb drive access.

I do not need the mhl to hdmi adapter plugged in to the 5 pin. I can plug charger direct.

If you built yours without the 11 to 5 pin adapter I recommend you try building it with the adapter. They are cheap from monoprice.com
[Galaxy S III Accessories] Telemachus:
Thank you, that is sound advise. I guess I assumed that the blue/green/red connections on both the 5 pin and 6 pin side were in continuity with each other. If they are not, then it would make sense that he MHL side is detecting the D+ and D- pins separately than the USB-OTG side.

Without a doubt the VCC and Ground are all continuous.

Looks like Monoprice might be getting another 5 bucks from me.

:p
[Galaxy S III Accessories] athlonxp2300:
Here's a pic of my cable and my other phone (t999). The mhl to hdmi adapter is unplugged and next to the phone. The 11 pin to 5 pin mhl adapter is plugged in the phone. The charger is plugged in the 5pin side of mhl. The USB drive is plugged in the otg side. This works for just Charging and usb access. It was a pain trying to solder in that cable style adapter.

Edit... Everything works as it should. If I unplug the charger from the 5pin connector and plug it into the mhl to hdmi then plug that into the 5 pin I have smart dock.
[Galaxy S III Accessories] lennyn:
wanna help.!

I have a galaxy note 3 and was trying to use the mhl adapter and otg while and I found this same problem.

I did some tests .

The mhl cable does not fit as it should had to remove the casing , to function without external power . Since they came to make the 11-pin contact .

For the mhl adapter charge the phone first the power must be connected to the adapter and then to the phone . otherwise does not charge the phone .

( When charging the phone appears as if powered by USB . Regarding what commented that feeding could be for the pin D + D- usb in my case these pins are not connected to anything, I add image to the end )

Based on this I think the accessories must be connected in certain order to be recognised..

Also try to create a usb otg adapter will charge the phone , but had no success.

Add an image with pin mhl adapter if I am willing to experience what it's worth

Sorry for my bad english i use google translate .
[Galaxy S III Accessories] athlonxp2300:
With my setup I connect everything but the phone and leave it connected. Then I just plug the phone in. It works just like a smart dock sitting there waiting for the phone to be plugged in or unplugged.

Charging is recognized as AC but is not as fast as the charger by itself.

The note 3 is different than S3 because of rev2 of mhl. Not all adapters will work that way. It is supposed to be able to power the mhl to hdmi adapter without a charger. This may be why you need the power connected first for the phone to charge. The S3 will not power the adapter and requires the charger connected to the hdmi adapter.
[Galaxy S III Accessories] gdebo:
Can someone indicate me where I can find a complete list of the pinout of USB3 of Galaxy note 3 (N9005) with a table of the sense resistor to enable the docks recognition? Thanks so much
[Galaxy S III Accessories] lennyn:
Just replace 1kohm resistance by 40.2 kohm
[Galaxy S III Accessories] athlonxp2300:
The same usa official smart dock works for usa variants of s4, note2, and note3. The 11 pin usb pinout should be the same as the s4. The resistances should be the same also.
[Galaxy S III Accessories] gdebo:
Thank so much athlonxp2300, but can you post me a link where I can find the pinout of S4 ?

Anyway usb3 has more than 11 pin: where I can find the meaning of the others
[Galaxy S III Accessories] athlonxp2300:
Posts in the 180's of this thread have pinout info for smartdock. Should be enough to get it working for note 3. It won't make usb3 compatible dock though. Maybe it is time to start a diy smart dock for note 3 with usb3 compatible.

Edit... usb3 host otg cables are available for note 3. Theoretically one could use an 11 pin to 5 pin mhl cable and a usb3 otg cable to make a dock. It would need to cut the 5 pin micro usb part of the otg cable off and connect those pins to the 11 pin connector the same as the regular otg cable is in this thread. Then the other 5 pins of the 3.0 otg cable (square side) would plug into the phone next to the 11 pin plug.
[Galaxy S III Accessories] lennyn:
But only will work with 3.0 usb device.?
[Galaxy S III Accessories] athlonxp2300:
No it would be backward compatible with usb 1&2

Edit... this is a very rough concept. 11 pin mhl plug and square part of usb3 otg that is not cut off would be put together and plugged into phone.

Working in Galaxy S4 with android 4.3 adding the second method posted here: http://xdaforums.com/galaxy-s3/general/hw-mod-usb-otg-charging-galaxy-s3-t1953061

Basically i follow instructions from first post in this topic; i did the resistor change from 1KOhm to 40.2KOhm in pins 4 (sense) and 5 (ground) add 4 wires for connect a female usb (otg port).

With the cable finished i connect 11pin to 5 pin adapter to mhl, charger, tv, usb mouse and s4, hdmi works but otg is not working, then i did a "key" with a male usb plug with a 330 ohm resistor between D- and D+ (a short works fine but i dont like put in short those pines) plus a led connected to VCC and GND only for power indicator.

Now i connect mhl, tv (hdmi) and "key" to s4 and to last attach the power supply, i wait 500ms or more for disconnect the "key", after i can connect usb mouse or keyboard or both (with a hub).

The circuit is to make the automatic switch, still not tested. At startup relay is closed, a combination values for R1 and C1 give delay before the relays open.
[Galaxy S III Accessories] zappacor:
Hi all,

back to the S3, any luck to get it to work consistently under Samsung stock 4.1.2 ROM? and what about stock 4.3?

Do they need to short sense-gnd for half a second to work?
[Galaxy S III Accessories] PeaceAndLove:
Anyone? I have the same question!
[Galaxy S III Accessories] zappacor:
I finally bought my S3 anyways. And after trying it on 4.1.2 could confirm the short is required.

However, I think even though it states "Charging (AC)" - please note the difference with "Charging (USB)" - it is not fully charging. Why? Because despite of that fact, the battery charge keeps going low and low until the phone shutdowns by itself.

Not enough time to place my multimeter in the middle to check it thoroughly yet.

Anybody did? Some happening to everybody out there?
[Galaxy S III Accessories] Alucard24:
Is there a way to enable dmart dock on s5 or to have usb otg+ hdmi at same time on this phone?
[Galaxy S III Accessories] zappacor:
After some time using it, I think having the CPU active and both the GSM radio as well as the WiFi on drains more power than the one the S3 sucks from the charger. So the battery charge goes sloooowlyyyy down instead of up.

That said, I'm enjoying it a lot and after installing stock 4.3 ROM this works better (better OTG kernel support for UMS and other stuff)
[Galaxy S III Accessories] vldesco:
Check with Galaxy Charging Current Lite how many mA are charging your phone, if it is below 400mA,maybe it is due to unstable current.

You should have to check your cable soldering too.

mhl and otg for gt-i9300 (samsung galaxy s III)

mhl and otg for gt-i9300 (samsung galaxy s III). i am using mhl cable with my s3 and hd tv. and i managed to solder a usb female for supporting OTG. its also working superb.
[Galaxy S III Accessories] woody1:
I would assume that this would work with any device that supports both mhl and otg. Can you tell us which wires you connected?
[Galaxy S III Accessories] lil11b:
Nope, the reason why mhl and otg can work at the same time is, that our s3 is one of the few devices having 11 pins, not just five. Also, the manufacturer has to implement this function, one plus one for example also has more than five pins but they are used solely for charging.
[Galaxy S III Accessories] woody1:
The same mhl adaptor that I got for my S3 also works on my Galaxy Tab S, so I would guess that your approach would work with other Samsung devices that support mhl and otg.
[Galaxy S III Accessories] Scopigno:
Please, tell us how you connected the wires.
