I also have notification problem, but its minor compared to SMS and phonebook.

Ghostly SMS doesn't help. I realize that during the time when phonebook is mysteriously empty I don't receive SMS.

After reboot my Phonebook is full but I don't receive the missing SMS.

Still don't know why phonebook is acting that way.
[Galaxy S III Accessories] scarrmrcc:
so, anyone taken apart an MHL adapter yet?

i have a sneaking suspicion, that the move to an 11 pin is what will allow BOTH OTG, and MHL at the same time, but i could be wrong.

look inside your USB port on the bottom of the S3...

whatya see?

the normal 5 pins on the USB part.. but what is that in back wall? THE OTHER 6 PINS!

yep, that is why you cannot plug the MHL adapter into a hub or anything.. there is 6 pins are missing.

Now, i am wondering:

has anyone taken it apart to see if the 6 pins are used alone, or if it uses the the USB also?

if it uses only the 6 pins for MHL-ness, then it should more than possible to make an OTG/MHL adapter/dock.

more thought says, if my theory is right, an 11 pin to 5 pin conveter may be the key.. and an otg can be spliced in to give 2 outputs: MHL in one (using an s2 MHL adapter) and OTG in the other.....

anyone wanna tear their adapter up? or are you guys gonna make me spend some money?
[Galaxy S III Accessories] cmbg78:
I ran across this post looking to see if anyone has done this yet. I am going to try to grab the 5 to 11 tomorrow and tear it apart (since it's the cheaper adapter). My plan was to rip it apart and if the original 5 pins are available, splice just as you mentioned.

I can't find a decent picture of the microUSB plug to see if all pins are there.

Also I found this:

http://homixtech.en.alibaba.com/pro...Galaxy_S3_11pin_To_Micro_USB_5pin_Gender.html

Which makes me think 11 pin microUSB plugs that work are available out there somewhere.
[Galaxy S III Accessories] scarrmrcc:
I wait with baited breath... i REALLY think this is what is going on.
[Galaxy S III Accessories] woody1:
So, did you do this experiment? Has anybody found a way to get access to all of the pins and make OTG work with MHL?
[Galaxy S III Accessories] nightwinn:
I've been waiting for two months for an answer about this. I'm glad someone started a thread. I kind of have this hesitation to start new threads.

I would love it if this could be integrated with the seidio active dock.

Edit: On another thread someone posted that they connected the USB OTG cable to the Micro USB port on the MHL adapter with no luck..hmm
[Galaxy S III Accessories] scarrmrcc:
meh, I think that is wrong. many people have done exactly what it says you can do, and it doesn't work.
[Galaxy S III Accessories] nightwinn:
Makes me wonder if the boys at Samsung made a press mistake. If indeed you can't use both with the correct cable, then why make a port with 11 pins? Seems a waste of resources to me.
[Galaxy S III Accessories] scarrmrcc:
I have never seen anything from samsung saying that MHL and OTG was possible.. just speculation in websites.
[Galaxy S III Accessories] Geordie Lad:
It better be possible because if not all Samsung's managed to do is make us buy hugely overpriced new MHL cables when they could have kept the old type, but I guess Samsung's made some decent money giving people no option but to buy £30 MHL cables.
[Galaxy S III Accessories] nightwinn:
I hope Monoprice really is working on a cable. 35-40 USD is more than I want to pay, especially if I get a couple and/or an HDMI dock.

Both the oem adapters are missing 2 data pins within the plug needed for simultaneous usb connectivity with mhl,I've ordered a Chinese alternative that I'm hoping will have all 11 pins,I'll report back If I have any success
[Galaxy S III Accessories] scarrmrcc:
gracias amigo.

when you get 10 posts, so you can post links, can you come back and post what you got? then I shall order a different one.

we will find the perfect cable.
[Galaxy S III Accessories] Geordie Lad:
Someone needs to find the resistor values first so the phone can use both simultaneously if it's even possible that is.
[Galaxy S III Accessories] scarrmrcc:
that would be key. I have sent out messages to people that may know, or may be able to find out, but i have not had success.

heck, If it can be done in the terminal (turning on items) i can make a shortcut that would do it.. but i have had no success with that either.
[Galaxy S III Accessories] Jeurum_92:
It's not possible I think.

You can use an MHL enabled tv wich powers MHL, (so you don't need the adapter) but how do you want to split that?

You can split the cables from the samsung adapter, so you have the MHL ones(6) and the usb ones(5).

But what then?

You need to connect the MHL ones to an hdmi cable, and connect it with an MHL enabled tv. And the usb ones to an usb port for OTG.

But will that even work with this S3?, because it is designed to get power from your charger via the extra usb port on the adapter.

Maybe it only works with the adapter, and not even with an MHl enabled tv...

I think somebody needs to connect the S3 to an MHL enabled tv, if that works you can modify the adapter and use the usb as OTG.

Send from my GT-I9300 with Tapatalk
[Galaxy S III Accessories] scarrmrcc:
I found (and shared) the MHL value, and we already know the OTG value.. but it only seems logical there is ANOTHER value to activate both at the same time. we are postulating, the the reasoning behind the 11 pin, is to allow both. If adding just an OTG cable turned on MHL too, it would cause issues without an MHL connection. and the same with MHL activating OTG, without an OTG device connected. like i said, this is postulation at the moment, but there SHOULD be a thrid value to enable both at the same time. that value would be used by a future peice of hardware that does a whole "PC MODE".

and if it does not exist, it CAN be done, we just need more "stuff" a way to enable a special switch if you will.

some people are saying you can connect straight to an MHL enabled TV, but that has not been done yet (and since there are no 11 pin MHL cables, that are not adapters, it seem unlikell that anyone will until said cable exists. the S3 cannot send MHL signal over the usb part, it has to be either the extra 6 pins, or with the 11 to 5 pin adapter.)

essentially, the pins are there, and with some special software, or a hidden resistor value as to yet, unfound, and some custom hardware (as of now NOTHING 11 pin, has 11 pins in it) it SHOULD be possible.

but there is nothing that has been found (hardware wise) that is even modifyable to work.... yet.
[Galaxy S III Accessories] Jeurum_92:
What I don't understand, why does MHL only work with the power connected?

They could easily make an MHL cable with the 11 pin, and hdmi. That should work for only MHL.

Only no go I can think is that MHL drains your battery because of always having your screen on, and the MHL output.

So they decided to use the adapter with power, otherwise you can't use MHL feature very long before your battery is empty

I think inside the adapter they only use the pins for giving power, and not the full 5 pin support for OTG, and therefore OTG doesn't work when you want to connect something.

Inside the ROM they have maybe build in something that MHL will only work when power is connected.

Maybe the solution is very simple,modify the adapter so full 5 pins are connected.
[Galaxy S III Accessories] scarrmrcc:
have you seen my teardown and pin mapping of the 11 pin to 5 pin adapter from the other thread?

i found what pin goes where, and what are used for what during MHL mode:

the top 6 pins (that makes it an 11 pin) are used for MHL signal and the other 5 pins use the nomral ground, and ground, power as power, and pin 4 (the witching pin) to switch on MHL.

your assumption is probably right for the reason we need to add power to MHL mode: they don't want the device dying part way through a a movie.

but, in the wonderful land of DC power, we can add powerwhere, irrelevent of the "mode" the usb port is in (host, or just component mode) as long as power is inserted, we get power.

so if the needed cable/doc was wired with:

top 6 to MHL (simple)

power to a powered usb hub

ground to the same powered usb hub

signals to the signals of the phone (As they are not used in MHL)

and pin4 would need to be a special resistor value that triggers both OTG and MHL (and then the kernel/firmware/or ROM detecting and activating both)

we would be in buisiness.

we are that darn close.

When I heard about the spider laptop dock it made me think back to this thread immediately. It will probably have to be a custom adapter that has USB power in, USB OTG out, and HDMI but it looks like that kind of setup is absolutely possible. Doesn't seem too hard for a person that can homebrew electronics. If only we could get our hands on a circuit schematic for the laptop to figure out the resistors and wire routing...
[Galaxy S III Accessories] scarrmrcc:
yep, that thread was on my mind too. once they become available, you KNOW someone here will get one, and it will be a simple task to get them to find the resistor value... then homebrew will be on it's way... unless..

I have a feeling that laptop does not mirror the screen, meaning it does not use MHL. As far as I understand (and assume) it uses it's OWN android OS, and uses the phone as a processor/secondary harddrive. that is only intelligent way to make it: so it is universal to all phones, not just limiting it to 11pin phones like the S3 (and probably soon be note II).
[Galaxy S III Accessories] Jeremy.Stewart85:
For the price I don't know if that's what's going on as it would require a decent ARM CPU and some local RAM. On the video it did seem to have access to the apps and messages that are on the S3 that was connected, although things like AirDroid can do that as well. It's hard to verify 100% but stories like this all say no RAM, CPU, or OS is local and it's just feeding off of the attached device.

I did manage to find the actual PR from KT which has some possible bad news. Sounds like the demo required custom software from KT (probably tablet mode + secondary screen support or something) AND firmware from Samsung which could be the key to enable the MHL+Power+OTG config. I bet this will need to be a custom thing for every phone that will be supported. Will definitely watch this closely..

[Galaxy S III Accessories] scarrmrcc:

the custom software.. is NOT a bad thing. if we can get it, we can mod it. :good:

plus your info, sounds good... looks like this may be the key to unlocking tablet mode for us homebrewers!
[Galaxy S III Accessories] skrypj:
looking forward to the results on this. The potential is huge. I was thinking of buying the samsung 11 pin, would I be able to help sort anything out by testing the pins on the male and female usb plugs using a volt meter to see if there is any interconnect besides power and ground? It was not clear if we know whether or not the data lines went to the power plug on the adapter.
[Galaxy S III Accessories] scarrmrcc:
As of yet, ALL 11 pin connectors don't even have the data pins inserted.
[Galaxy S III Accessories] Jeremy.Stewart85:
youtube /watch?v=UcUgpMIgZXk

That video shows the adapter pretty close up. Physically it's nothing more than MHL -> MiniHDMI but obviously there are a lot of other connections going on behind the scenes. Even standard HDMI does support more than just A/V including power and ethernet, they've just gone and bundled up everything into one nice custom package. Unfortunately it looks like that company doesn't sell that adapter by itself as far as I could tell on the site (olleh DOT com). It might be possible to reverse engineer everything from that MHL adapter but its also entirely possible that the laptop does more magic once the wires get there as well.

I do have access to a couple of service manuals for the phone (from the bootloader unlock thread, see also http://xdaforums.com/showpost.php?p=24100141&postcount=1968) but it doesn't mention anything about resistor values for the USB or OTG IDs and there's very little mention of MHL at all. There are GPIO pin outs that might be interesting to people that know what they are looking at but I can't really tell what might be useful.

Suggestion for the resistor value

ADC_DOCK_PLAY_PAUSE_KEY = 0x0d,
ADC_SMARTDOCK	= 0x10, /* 0x10000 40.2K ohm */
ADC_CEA936ATYPE1_CHG	= 0x17,	/* 0x10111 200K ohm */
ADC_JIG_USB_OFF	= 0x18, /* 0x11000 255K ohm */

Thinking about ordering this 11 pin MHL cable off ebay (ebay com/itm/Sam-sung-Galaxy-S3-SIII-i9300-MHL-Micro-USB-11pin-HDTV-HDMI-male-Adapter-/130766714497?pt=LH_DefaultDomain_0&hash=item1e724db681#shId) to do some testing with or at least find out if that USB port has more than just the power wires connected (the pins are there on the USB connector if you look at the close up but who knows if they're attached through the HDMI part and all the way to the MHL adapter).

Nice find heinstein! I want to try adding the rheostats off of here: sites google.com/site/sonicboomworld/my-projects/otg-charging-for-samsung but I guess those wouldn't be able to hit 40.2kOhm combined so I'd have to get something beefier. I wonder if those resistor values could be modified in a modified kernel so that the normal MHL adapter could be used as a smartdock. Inching closer and closer...

I'm looking for a way to connect my 5pin phone (gnex) to my 11 pin mhl...

Any ideas?
[Galaxy S III Accessories] scarrmrcc:
judging by you posting it in THIS thread: no, you cannot EVER get MHL+OTG on a 5 pin connector..

also, you CAN build an adapter to get your 5 pin to the 11 pin.. BUT it would cost more in parts than just buying a 5 pin MHL adapter.
[Galaxy S III Accessories] jeetS:
Thanks. Im not looking for otg... I just have a mhl adapter for a s3 and I'd like it to work on my gnex as well...
[Galaxy S III Accessories] scarrmrcc:
it would still be easier, and cheaper to have an adapter for the gnex, and then an aadapter to use the s3 on the gnex adapter.

there is no 5 to 11 adapter, but there is an 11pin to 5 pin.

manufacturers don't really expect people to buy a new tecnology for thier old devices, but it is common to have old tech and then get a new device.

no, to make you own, you need to first FIND an 11pin female socket (have fun, they aren't exactly common nor are they cheap) then a male 5 pin (easy). then wire them togother backwards to what I posted on my teardown of my 11 to 5 pin adapter. and add a resistor.

OR

just buy a cheap 5 pin MHL adapter, and a cheap 11 pin to 5 adapter, and be done with it.
[Galaxy S III Accessories] ZenInsight:
The HDMI part of the split HAS to be powered...but the USB OTG does not. So...if there was such thing as an 11 pin micro usb Y splitter, then the OTG side would work while the powered MHL adapter was on. Essentially this is what the dock does.

Is it possible to create an 11 pin Y splitter? Then we do NOT have to use a dock for the OTG and HDMI to work at the same time.

Edit. SOME company will make an 11 pin Y cable splitter...and all of the SGS3 and GSNII folks that don't want a dock will get one.

I have a Note II also. Try a racing game and check for delay in actions for steering and if you can the gyro movement compared to the screen when the app is on (no image on your Note II).
