But you can use a HUB with external power supply (is it easier)

Description of how to do the OTG adapter for those who have a normal USB Micro B adapter - USB A.
The micro USB connector pin 4 not connected, connect it to pin 5. You have to remove the gum with a knife to expose the plug contacts. Then a thin wire to connect pin 4 and 5.

And this is all the work. If you perform everything correctly, you can connect to our MediaPad memory, keyboard, mouse.
Good luck!
There's quite alot of these cables on eBay for $2.25 shipped. Ordered mine, made sure to do a semi-local seller, got it two days later.

So will a HUB like this work fine? Or does it need an external power source?
Also, if I connected 2 male USB into the HUB and one into a wall charger, will it charge the phone?
Definitely needs power because I tried an unpowered hub with flash drive and phone crashed.

Did it just crash or explode and caught a small fire?
Dunno I couldn't find the Black Box. But yeah it just crashed and rebooted after a few seconds.
Will be work USB OTG with classic micro usb cable, for example from charger + this connector which is USB-USB?

No.
I had got one of these for my Galaxy R hoping the same as you do, but it didn't work. Some information digging later I realized that you need a (micro in this case) USB connecter that makes the phone act as a host.
This dual connecter can only be used to extend a cable or something similar.

If I know, Galaxy R dont support USB OTG. Did you try it on your SGS3?
I'am looking for an OTG Cable with USB power like this one that can charge the phone and not power the female USB ...

bought one on ebay, but power doesn't work with my GN3 ... but work with an Galaxy S1 ... what is the problem ? anyone get one working ?
Maybe the problem is that since the note2/s3 Samsung changed a lot of stuff to an 11 pin connector as for the s1/s2 it's a 5 pin. As for a normal otg cable, it works for me at least (I have one w/o a charging cable)
Sent from my SM-N9005 beast of a phone.
I wanna connect a hard drive to my Z2 with an OTG cable, but don't know if it works
Only works with an otg cable with external power supply
