Umm, didn't you seee the adapter with the SIII on it? Isn't it obvious that you need to use it? Omg, the people nowadays. It says right on the effin adapter SIII. What do you think you use it for? SIII means S3, be it either i9300 or i9305.

Update : Alex I used it with the adaptor MHL and it still had no image. The problem was coming from the HDMI cable (I think there is a problem with different HDMI versions)
Now, I have everything working (keyboard or mouse or HDMI) but not at the same time.
I cannot unlock my screen. That is soooo dumb : I tried many times with the mouse or with the keyboard but no luck. It seems to be as simple as pressing ENTER on my S5 but I cannot replicate that on my S3.
It get stucks in the home screen - I said lock before but it is not really a lock...
I am now tring to find a solution using Vysor.
Unfortunately, I dont know how to enable the developer options with no screen Maybe using command line with developer tools... no idea...

It would be easier if you would flash stock with odin, so you have no lock.

When I reboot, there is no lock... but still it seems my OTG with the mouse is not working...
So I am trying with ADB tools to use that : http://forum.xda-developers.com/showthread.php?t=2786395
I am now stuck at the USB authorization from the computer to the phone : http://forum.xda-developers.com/galaxy-s3/help/folder-data-misc-adb-adbkey-device-to-t3398376
RRRRRrrrrrr :crying::crying::crying:

If you have normal OTG connector (I mean just microUSB to USB a female adapter) you can try to use mouse with it. Maybe the MHL hub that You showed in 1st post makes some problems with OTG

Proprietary to USB-female?

Is there a cable for the prime for USB host? I want a USB port but so far I can only find cables for the Galaxy tab or for micro USB ports. I don't want the keyboard dock, I have my laptop for computing. I just want a cable for it. So far I can only find the Asus dongle for the TF101(compatible right? Same proprietary port?), but that's only for an SD card, not a USB-female port.
Do you mean this? If you need to hook up a usb device to the prime, you need a dongle like the one below.

That's exactly what I meant, thanks! And sorry about that, fixed.
No problem
Would something like this work with the charger/data cable that comes with it?

good question, i was looking at picking one of these up so i could use my ps3 controller with my prime's included charging cable.....
http://www.amazon.com/HDE-Female-5-Pin-Male-Adapter/dp/B002S7PS8M
USB female to mini-usb male.
would this work and do i really need to shell out for that box, i just don;t understand what exactly it does, i think for what i'm trying to do it should be fine, i could see the issues when trying to use a usb hdd as i could see more drivers needed to even access the data from the drive....i would think a ps3 controller would just show up....any suggestions or buying some extra box to carry around 100% necessary....

Bought this last week thinking the same thing.
Does not recognize devices. Something is weird about the dock cable.
I was trying to pair my PS3 controller, I ended up doing it with the keyboard port instead.
On a somewhat related note, I dont recommend you buy the item at that link. I ended up chucking mine out because it was too loose to hold the cables in... and its mustard yellow...eww
I've yet to confirm this myself, but I believe the dock connector uses different pins for "USB Host" (ex: plugging in a controller to the tablet) and "USB Device" (ex: plugging the tablet into a PC) modes. Using a USB Female-Female adapter, as others above have proven, will not work.
Wait...I spoke to soon, the link above is useless. It's backordered and I can't find it anywhere else. Anyone have an idea?
I got mine from microcenter, in tustin, ca. There might still be one there. And yea I first tried a female to female adapter on the usb charging cable it came with and no dice. However this adapter does work. Plugged my 360 controller in and played some shadowgun.

Use old lapdock as a tablet dock?

Backstory:
I have a lapdock from my old Atrix that had the LCD go out on it. I was wondering if it would be possible to just use it as a battery, keyboard, and usb hub for my Nexus 7. I took apart the dock to access the micro usb plug to go into my Nexus 7 but have no use for the HDMI. However the lapdock is enabled when a device is plugged into the hdmi.
Question:
How do I enable the lapdock without anything plugged into the HDMI.

Can you get any pictures? It would be helpful.
If you the cables out, have you tried plugging the microusb into the nexus 7 and the microHDMI into the phone(to power it on) to test whether the nexus 7 even detects the keyboard, mouse, charger of the dock?

I Don't have any devices with micro HDMI anymore (Atrix went to craigslist). I ordered an adapter for regular USB but from China so who knows when I'll see that.
The nexus 7 doesn't support HDMI out at all. Google confirmed that... What you could do is make some like of dummy or I read somewhere to short some wires... Read before you do anything though...

I know the Nexus 7 doesn't support HDMI. Thats why I'm here asking if anyone knows how to short the HDMI. Having trouble finding anything on it.
sorry for digging and old thread but until now im using the lapdock as otg hub, a keyboard and track pad. i have to remove the lcd screen since i have no use for it. very useful indeed up to now 2018. i usually use this setup playing pubg mobile. i dont a tablet but probably it also works
if you have a broken lapdock lcd, then you can have mine for free. except you shoulder the shipping of course

a little bit off topic but I have bought 2 USB OTG cables off eBay and neither works with my Z ultra, but they do work with the wife's Note 3. Does anyone know if there's a setting I'm maybe forgetting to turn on or if I need a specific cable?
There's no power at all going to the devices I connect, have tried everything from keyboards, thumb drives and dualshock controllers.

The one i bought from Amazon a year ago works perfect, it was $1.99
I didn't do anything special to get USB OTG working.
It could be that your USB device is drawing too much power, which a Note could manage but the XZU can't?
I don't (yet) have this phone, so maybe I'm missing something...
Why not flip the phone the other way, so the USB port is on the top?
the fully rectangular version is from when not all devices supported otg so they made them that way as a sort of failsafe to stop unsupported devices being tampered with (i personally believe it was to coin in further on cable replacements on high end devices)
if you have one of the old rectangular otg cables laying about just carefully file away at the edges a little bit until it fits smoothly (dont force it!!)...
tested with an old nokia n8 cable on my lg g2 and it works just fine!!!

the book cover/case I use has a crease so it can act as a stand, and the phone ends up held with the USB port bottom/right. It then leaves the mag charge port free for power.

Two problems with SGS3

Hi, guys, I purchased an used SGS3 and my battery seems to charge slow. I downloaded Galaxy Charging Current and I'm attaching two screenshots below. One is from the AC and the other one is from the USB cable. Is there anything wrong with it?

And my second problem is that sometimes when I connect the phone to my PC it keeps connecting and disconnecting until it finally connects. What do you think? Is the micro USB port faulty?
Most likely a faulty usb cable. Replace it, try again.
Next time, a quick search before posting, usb cables malfunctioning are a very common problem in the forum.
Can I use the USB cable from my old phone? Is there any diffrence?

Not true. Samsung's usb cable sucks.
Any standar micro usb cable works. I've used generic, from xperia, from blackberry.

Can be a charging cable fault change it. If the problem persists.
Then you are having trouble with your charging slot. Yes the hardware charging jack.
It might have been oxidised and thus preventing a proper flow of current.
Your both problems refer to the same cause. Either the charging cable or the (hardware) charging jack. Replace either of them and you are good to go again.
And secondly Samsung DONT block any NonSamsung cable. Even in many cases other cable are found to work more smooth and efficient with Samsung phone as compared to original Samsung cables.

No, there is no such thing. MHL is a digital standard, all the things you each want to connect to are analogue.
You are trying to put diesel in a petrol car, it just won't work.

Yes you can actually convert digital to analog by using an active converter, but that is somewhat expensive and unless you absolutely want to use it it's useless. Link here and also you will need a female to female adapter here for it to work. I have not personally tested but it should work (in theory).
Err, no. There is no MHL to VGA connector for the S3. You've found HDMI equipment, which uses the same plug but would ignore the signal -like plugging an S3 into a HDMI TV that doesn't have MHL, nothing happens.

How about this ? First, you are wrong abut the TV. No TV in existence has MHL. MHL is a standard for MOBILE DEVICES, not TV's
a HDMI TV that doesn't have MHL
Click to expand...
Click to collapse
so any adapter from HDMI to VGA that is active will work. Please do a bit of research before you post :good: . And then from VGA to SCART or RCA you will also need another adapter.
Lol, the op wanted to connect a mobile phone to a t.v.so yes, MHL is required in both the phone and the tv.
Relax, chill.
