[Galaxy S III Accessories] a32quaeler:
I have mixed news for you on using the S3 plus the Smart Dock EDD S20E together with the Lapdock:

Today I received the official firmware update to 4.1.2 via OTA (German S3 I9300, unbranded). With that stock ROM update the Smart-Dock works with the S3 I9300 as expected; that is simultaneous use of USB-OTG and HDMI-output plus analogue Audio-Out.

It works also with the Atrix Lapdock when using the right HDMI adapters/cables and the S3 screen is displayed on the Lapdock and touchpad+keyboard are recognized and usable. The audio-output can be switched in the settings from HDMI to the jack on the Smart Dock - so no problem with using headphones for videos as well.

HOWEVER, unlike when using the allshare cast dongle, the (home and apps) screen is vertically squeezed again (like for the "red" MHL adapter described before - presumably a 720p vs 1080(i) problem). Video controls and 4:3 videos are displayed filling the screen (i.e. not in the right aspect ratio=> 4:3 content filling 16:9 and 16:9 content on 16-to-(0.75x9)) :(

and

the output power of the Lapdock-USB-port is not sufficient to fully operate the Smart Dock. "Fully" means that I have HDMI-output working then but the USB-hub in the Smart Dock is obviously not powered and thus the touchpad+keyboard are NOT detected (strange). I tried to use both USB ports of the Lapdock with a Y-cable but that didn't work. So, the Smart Dock has to be powered by its own wall-plug (2A - or the one of the S3 (1A works as well)) which strongly limits the mobility of it :( :( There might be the possibility to get around that by using the +5V from the Lapdocks micro-USB together with the "normal" USB ports but that would require some soldering.

To my own surprise, I will have to stick to the allshare cast dongle solution for using my Lapdock while on the go...

P.S.: the S3 screen goes blank and HDMI-output in landscape mode (without rotation control apps) ONLY when using an additional mouse plugged in on the Smart-Dock or the Lapdock(!) - the Lapdock touchpad/kb do not trigger this specific dock-mode behaviour ...

Flash an ICS rom, and you'll be a happy man, trust me.
[Galaxy S III Accessories] P0ll0L0c0:
That's disappointing - and kind of what I expected. For that reason - I bought an Android usb stick, to better run my lapdock, because i don't think my phone will totally cut it. The allsharecast works - but not having an easy headphone out makes it frustrating.

connection issues

Hey there,

I have connectivity problems with my lapdock and Samsung's Smart Dock( and other devices) .

The lapdock doesn't recognize any HDMI input-signals.

I bought these cables and adapters

1. ebay.de/itm/271025182047?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649#ht_1648wt_1065

2. amazon.de/gp/product/B001C6G5C8/ref=oh_details_o05_s00_i00

3. amazon.de/gp/product/B008HNUFC0/ref=oh_details_o03_s00_i00

+ all the USB connectors that are necessary but unfortunately there's no chance to deliver a signal to the lapdock :(

maybe someone has an idea what else I could try (e.g. different cables?)
[Galaxy S III Accessories] souljaboy:
Look, I replied to the other guy a32 and sent him a pm to go back to ICS. He didnt reply anywhere.

The reason is, in the JB android they messed up HDMI connections, even the motorola phones dont work properly with lapdocks since JB.

Bionic dock gives bad resolution. Lapdock 500 gives no signal like the guy above me.

So, before you blame and buy adatpers, dongles, cables, just try an ICS rom, and you'll see whats the problem.
[Galaxy S III Accessories] a32quaeler:
Hi, I disabled PM-notifications... that guy above also wrote about his problem on the German Amazon site and we actually solved his problem: In this specific case it was indeed one of the adapters which didn't work properly.

However, concerning ICS I would try it if my S3 wasn't relatively new and my carrier has some specific restrictions about that. Probably - if a future 4.2 will be disapointing - I will try that. Besides that I'm relatively happy with the JB 4.1.2 functionalities like the "low light shot" mode in the camera app or the notification bar settings. I would actually prefer to have some settings for the HDMI output instead of going back. As far as I know (and I did not read much about that) is the main problem with the Motorola phones and JB the fact that the specific "webtop" mode for the Lapdocks did not survive the transition and not the HDMI output capability itself...
[Galaxy S III Accessories] souljaboy:
The webtop mode was not included with the new motorolas, the RAZR HD and Atrix HD, it was only mirror mode, but it was fullscreen in ICS.

Now, with JB, it looks exactly the same as it does for you, I'm pretty sure its an android JB global screw up, the HDMI settings are gone for everyone after all...

Maybe its a default setting of the rom that could be fixed, but maybe it got removed when they did project butter with the 4.1 kernel.

Btw: What didnt work with his adapter?
[Galaxy S III Accessories] a32quaeler:
Thanks for the Info - HDMI seems not the only thing they messed up with JB ... the adapter was the 90-degree HDMI one which in his case did not trigger the Lapdock to detect a device on its HDMI port and causes it to power up. As already written here, you need adapters that correctly pass through all wires for the HDMI-CEC-Ground-contact or provide it by themselves (as the other 90-degree adapters did)... It worked for him to directly connect the dock to the HDMI-to-micro-HDMI adapter (which is no permanent solution).
[Galaxy S III Accessories] P0ll0L0c0:
You got your lapdock to correctly work with an s3 on an ics rom, using mhl?

I only recently got the jellybean update, and even before the image was stretched using mhl. The same thing happened with my ics evo 3d.
[Galaxy S III Accessories] souljaboy:
sadly, its not a galaxy 3 that worked with it, i have a motorola myself, but having same problem since jb update.

bad side, installing ics on any phone wont fix it.

good side, the problem isnt with jb, because some ics roms act the same.

we would need someone like chainfire, to add supported resolutions into the kernel. or maybe some other top kernel/gpu dev. i think it would be pretty easy to do though, just a simple find/change the difference between supported and non supported roms.
[Galaxy S III Accessories] bapsack:
well after all my chinese adapter came from here......

http://www.ebay.com/itm/280761232832

and my micro hdmi male to hdmi male cabel from here.....

http://www.amazon.de/gp/product/B004QIFAO8/

I´m sad to say that the lapdock stays dark.....

I ordered another micro hdmi male to hdmi male cabel.... but still the lapdock wont start......

I contacted rob86 from http://www.robpol86.com/index.php/Atrix_Lapdock_Other_Uses

who confirmed that his chinese adapter just works fine....

So I first have to check out whether my lapdock has a defect and then will continue

hoping for an happy end

or is there any trick to get a lapdock working for the first time?????

ps and btw my s3 and the smartdock works okay, as tested in my office with hdmi monitor and USB mouse and Keyboard.... so there is no failure and no, i´did not update my rom..... ;)
[Galaxy S III Accessories] 91rangerturbo:
Ahh man that stinks. I am just about to give up on this and just pickup a tablet.
[Galaxy S III Accessories] P0ll0L0c0:
Have you tried another HDMI device with the lapdock? I think it's far more likely that your adapters are defective. I had to return/replace a couple. If there's play between the adapters and the dock - you will lose signal. If I were you - I'd jiggle the micro HDMI cable.

To test the lapdock, I would do the following:

1) Charge the lapdock of course.

2) Connect only the micro HDMI adapter to the dock, whatever you're using. Does the light on the trackpad light up? It should - an HDMI signal powers up the dock. If not - either the adapter or the dock are defective.

3) Connect the MHL adapter (or your smart dock) - to your phone, and power it up.

4) Connect the MHL adapter to the lapdock. Do you get a signal?

5) Move the cables between the MHL adapter and the dock. Does the message that says "No signal" on the screen of the dock even flicker? Do you evern get that message?

Good luck. But keep in mind, even if it works - the image is going to be stretched so as to be practically unusable. The SGS3 is only useful with the allsharecast in my opinion. I ended up buying an Android stick to drive my lapdock instead, and when I need to view content from the SGS3 - I use DLNA to stream it.

I've gone back to ICS and the image is still stretched - so it's not the rom version... this really sucks!
[Galaxy S III Accessories] MisterTedster:
Sorry if I misunderstand, but how does this give us usb host otg and hdmi output?
[Galaxy S III Accessories] electronbee:
They don't. It's pretty obvious that they are normal USB OTG cables with charging capability. If, it was as simple as changing wiring then they'd be all over eBay via Chinese sellers by now.
[Galaxy S III Accessories] GoldenBadger:
The cables will not help with HDMI just with charging and OTG.

Have ordered the cables. Will test and give feedback as soon as i have them

Does keyboard work with Allshare Cast dongle?

I've got my allshare cast dongle hooked up with the proper cables and I have my GS3 being charged by a USB cable running out of the lapdock. It mirrors my phone onto the screen and looks pretty good, but the keyboard does not work at all. Am I doing something wrong or is there no way to get the keyboard of the lapdock to work?
[Galaxy S III Accessories] a32quaeler:
Either you charge the S3 by microUSB OR you connect the Lapdock keyboard etc. via USB-OTG. Currently I do not know any alternative to that (except for the "smart dock" - but that has the HDMI-scaling problem). Probably look at some earlier posts in this thread where we discussed that you need indeed the OTG-Signal (ID pin 5) for the USB host functionality of the S3 to work ... which in turn prevents it from being charged (unless you have some resistors soldered for "dock modes"). For having that I used the (female) microUSB-to-microUSB(male) cable from the (male) microUSB plug of the Lapdock (with the +5V red wire cut) PLUS a (microUSB-to-USB + USB-to-microUSB_OTG) adapter "chain" to the S3 USB-OTG (you may want to look at the pictures posted earlier - see post #18).
[Galaxy S III Accessories] harpdoc:
a31quaeler, thanks for the reply and your patience with explaining and posting pictures. This is starting to make my head spin. I guess I was using it in "entertainment mode," but getting to "productivity mode" is the challenge. Looks like I have everything that you have except the microUSB-to-USB and USB-to-microUSB_OTG adapters.

I also have a microUSB_female-to-microUSB_male cable that looks just like yours. What I'm confused about is the part about the 5v red wire being cut so that it doesn't charge. This seems like a bit of a delicate operation. Can you give any tips/pics on doing this without ruining the cable?

Finally, there are the links above to cables that allow simultaneous OTG and charging. Any thoughts on these?
[Galaxy S III Accessories] a32quaeler:
Well cutting the red wire which carries the 5V in the USB cable is not as complicated. There are some guides referring to this which mostly originate from the use of the lapdock with a raspberry pi (actually all of that is not needed anymore for newer revisions of the RasPi). Like

http://weblog.mrbill.net/archives/2...ock-as-a-hdmi-monitor-and-usb-keyboard-mouse/ or a video

http://rpidock.blogspot.de/ where they cut and rebuild the entire cabel (much too complicated). You simply have to gently cut (carve away) some of the surrounding insulation and find the red wire, cut a small segment out of it (just to make sure it does not "re-connect"), re-insulate it with tape and that's it. If something goes wrong ... well, I paid for that cable 99cents (and bought 2 of them - just in case).

Presumably there is a more intelligent way to signal the OTG mode than using the two additional adapters (any OTG adapter will do as second adapter) but this is one without any soldering (and I had them anyway). I didn't have a closer look at those cables but in my opinion, they don't help at all to charge the host (the S3 in our case) but are meant to provide additional power to the connected USB-device from an external source - e.g. for HDDs (which would be in our case the lapdock which does not make sense at all). The S3 is a bit too intelligent and expects the right resistor values at the OTG signal pin to switch on simultaneous charging and OTG (e.g. with the smart dock) and none of these seems to provide that.

Very helpful stuff. Thank you!
[Galaxy S III Accessories] @rbiter:
i wish samsung would hurry up and restock the smart dock. geez. this is killing me. i want to get my $200 worth out of my lapdock. i am sure once we get more people interested in this we could hire a dev to write up kernel to support more resolutions and maybe optimize this.
[Galaxy S III Accessories] P0ll0L0c0:
Sheesh, I hope you bought yours a LONG time ago. I paid $50 new for mine. If anyone is still looking for one to play with, I recommend the Bionic lapdock. I've had both Atrix and Bionic, and while functionally identical - the Bionic has more room for cables without having to shave.

I have also given up on the GS3 to drive it. I bought a mini android pc (uhost 2) and just stream from my GS3 when needed.
[Galaxy S III Accessories] Ironman1965:
I have the smart dock and all the cabling. I've been experimenting with the Linux on Android project to see if the resolution issues displaying on the lapdock can be overcome with no luck.

I've attempted configuring linux to output 1366x768, 1280x1024, 1280x720, and 960x540 all with no luck. The screen is either cut off top and bottom, normal squish, or small.

Seems like the larger resolutions would be correct save for the top and bottom being cut off.

Can't peg down where the fail seems to be coming from, hardware or firmware. Wish I knew more about the HDMI protocols.

Oh BTW, I there are 2 mouse cursors on screen when in the linux interface. One at the scale you would expect for the DT, the other is larger and seems to be lower resolution, and this is the one controlling the DT. The small high res cursor just sits in the middle of the screen. I do lean more towards the firmware/kernel being the problem, but don't have enough knowledge to be sure, but wouldn't be supprised after the whole dock mode fiasco.

Hope this info may be of use to someone with more knowledge in these areas.

Cheers.

I finally got it working using a32aquaeler's setup, with my AllshareCast dongle. It really seems like more of a proof of concept experience than something that's very usable to me. Between the many adapters and cables, trying to get the dongle to connect consistently and stay connected, and trying to navigate the screen, it's all a bit difficult. Perhaps if I were writing a long document in a wordprocessor it would be worthwhile. Perhaps I just need more time to get used to it.

One of the things that I find difficult is navigating around the screen without using the buttons on the phone itself. Has anyone figured out how to navigate back, home, and settings without using the phone buttons?

Another challenge Is getting the screen to stay in landscape mode.

Any tips for a smooth user experience?
[Galaxy S III Accessories] harpdoc:
I've been playing around with this since my last rather negative post and have a more positive outlook now. I've found a way to make the setup pretty useable. The key for me is to use a mouse on one side of the lapdock, and have the SG3 on the other side in landscape mode. That way I use the mouse for most navigation and the phone itself when I have to use the Home, Settings, and Back keys. The scroll wheel on the mouse also rotates between home screens (at least with Apex Launcher), which is very convenient.

The other key, which only works when an outlet is nearby, is to use wireless charging on the SG3 while using the lapdock. There are various threads on this forum for how to modify Palm Pixi parts to wirelessly charge the SG3. By doing this we've solved the dilemma of how to charge the SG3 and be connected to the lapdock with the Allshare Cast dongle. The Palm charging base also puts the SG3 at the perfect angle for viewing/using while connected.

I'll post some photos when I get time.
[Galaxy S III Accessories] a32quaeler:
My allshareCast dongle connects very well, and keeps the connection stable especially since its firmware was updated by Samsung to "LJ02".

To keep the S3 in landscape mode (including the home screen), I use the app "ultimate rotation control" (no rooting required - there are other similar apps out there as well) and lock the rotation with its widget.

The "back" function is mapped to the "ESC" key and of course to the RIGHT mouse/touchpad key. The "home" function is mapped to the "middle/third" mouse button (if you use an external mouse) - I never use "home" anyway. I navigate and select with the cursor keys plus "Tab (-->|)" and "Enter" through the icons and apps. The only thing missing is the "settings" button on the keyboard. There are apps like "external keyboard helper pro" which you can use to map any keys to android keyevents - I actually have it installed (for German KB layout) but never used that functionality since I don't really need it - I may try that soon... stay tuned.

I usually place the S3 right to the lapdock to use the multitouch/pinch to zoom etc. capabilities if needed. Personally I am quite happy with its usability and use it often while on travel.

P.S.: I actually noticed that the "external keyboard helper pro" app might by responsible for the Escape-Key-to-Back mapping by default (don't know if it works without the app). I recommend that app in any way.

-- I now see that you posted a more "positve" post while I was writing my answer on using it with a mouse. The Idea with the wireless charger is very interesting indeed...
[Galaxy S III Accessories] harpdoc:
Attached are a few photos of my setup. Thanks for the tip on External Keyboard Helper Pro. There's a bit of a learning curve, but I think it's going to be great. So far I've got the Home, Menu, and Back keys mapped, as well as several of my favorite apps. This is proving to be a sweet setup!
[Galaxy S III Accessories] a32quaeler:
Looks good. I'm wondering how good the wireless charging works while the S3 in OTG mode since someone posted in another thread that charging via the pins for wireless charging and simulatneous use of OTG resulted in a shutdown of the S3 (http://xdaforums.com/showpost.php?p=37897378&postcount=5). However, he was obviously directly connecting a charger to the backside pins which may not be the safest way to do it.
[Galaxy S III Accessories] harpdoc:
I've never had a single problem with my phone using the wireless charging and I've had it for several months. The Palm Touchstone bases are so cheap that I've got 4 of them in various places and almost never plug in anymore. About $20 to get the parts, and additional charging bases are less than $10 (the new wireless base for the Nexus 4 is $60!)

Forgive me. I read through the posts but got lost in the details.

Is it possible to connect the Galaxy S3 to a lapdock?

If so, what connectors are needed?

Any hardware mods on the lapdock needed?

Does the phone need rooted or custpm roms?

Will the screen be "stretched" on the lapdock?

Thanks for any help.

I have a Samsung Galaxy S3 i747.

No offence intended rlridgeway, but this forum and thread are for the i9300 s3 variant. Your phone and the i9300 have different internals. The i9300 can be connected but at a $ cost. I don't know if your variant can be connected or not. Try the forum for your specific s3 model. You may find what you are looking for there. Good luck.

[Galaxy S III Accessories] delucz:
By the way I wonder if anyone has tried one of these: http://handheldsci.com/kb

Using the correct adapters, you could potentially use the MHL adapter to get HDMI to the laptdock, and then convert the lapdocks keyboard / mouse to bluetooth with the adapter in that link?

Cheers
[Galaxy S III Accessories] flyingpants:
I wish someone would update this thread.

That would definitely work and it would solve everything. You could use HDMI-out on any phone that supports it, and charge over USB like normal. Then just use the bluetooth kb/mouse. No need for USB-OTG at all.

So that solves that. Only problem now is finding such an adapter. I don't think they're very common.

Edit: nevermind, that one is $59 and it doesn't support mice. The only other one I've found is $75+. Dead end.

If I absolutely had to pick 2 out of 3 things between HDMI output, kb/mouse functionality, and charging. I'd take the first 2 and forget charging.

I have an extended battery for my S3, and the phone won't take much battery with the screen off. With a simple hardware mod, I can always switch it back to charging mode by switching to a different USB cable (and therefore disable kb/mouse) while watching a movie or reading something. If I want to use my lapdock for 8 hours straight, I can charge a spare battery for my S3 in a wall outlet and simply swap it whenever it goes dead. I think I would rather carry a spare battery than anything else.
