[Q] USB OTG on Galaxy S

when do we have USB OTG supported for our galaxy S? yesterday I heard some news about USB OTG mod on Xperia Mini Pro. I hope we can have it soon

Does usb keyboard need external power on original Galaxy Tab?

Will I need a powered Y cable to use a usb keyboard in OTG mode with CM10 on the original Galaxy Tab 7 ?
Are there any particular usb keyboards that are power thrifty enough to work without extra power?
Thanks for any ideas!

No. You only need the otg cable to connect any usb device. The keyboard is powered by your Galaxy Tab. I ordered one myself on ebay but I don't like it, I'm always afraid to damage the otg connection of my gt2. I ordered a bluetooth keyboard instead, completly wireless. The otg cable is only 2 dollars on ebay.

Thanks for the reply theriado but the original Galaxy Tab does not supply full power to the usb port like the Tab 2 does.
In fact the otg drivers were never official unlike the GT2 someone hacked them together.
In any case I will find out maybe this weekend if my cable ever arrives.
I was hoping there was also a hack to turn on otg without an adapter like some devices can do but no-one has ever replied about that one either.

i think the MHL should work not the regular HDMI cable. make sure you plug in the power adapter to the cable, before you plug it in to your phone.

[Q] HDMI port issue

Hi team,
I just bought an HDMI cable to connect by phone to the TV. The problem is that the cable just wont fit in to Note1. However, it works perfectly fine with Note 2.
I can use the same charger to charge my Note 1 and Note 2. But the HDMI cable port just wont fit inside Note 1 as if its not meant for it. I tried to push it but it refuses to connect.
AFAIK, HDMI cables are universal and can be used on any phones which supports this feature. I may be wrong.
Any ideas what is causing this issue?

Don't know how it looks on Note 2, but all Note 1 has is USB port into which fits only USB.
Sending screen to other devices is done with MHL converter, which has USB plug which goes to Note, USB port for external power and HDMI port for connecting to TV. I'm sure more info can be found in accessories forum.
PS. I have a vague feeling that questions should generally be posted in Q&A forum...

The man is bang on, there's no hdmi port on any phone AFAIK... Mhl ports vary pins on generation of phone, so the note2 matches the s3 and I think the s2 matches the note, but it usually states on the product page which models they fit.

Hi there, It looks like a Y shaped cable. One end goes into the phone (charger port) and on the other side, there are 2 wires (ports), one goes into the HDMI port on the TV and the other goes into the USB port on the TV. The USB port does the job of charging the phone simultaneously while the HDMI does the job of extending the screen from phone to TV. There is no MHL adapter. The cable does all the job.
On the package, it says for Galaxy S3 so I guess it will work only with S3 and Note 2. I need to buy one more which is compatible with S2 and Note1.
My only question is that since the charging port on Note1 and Note2 is similar, how come there is still a compatibility issue with Note1? I was under the impression that the cable/port would be standard for these Samsung android phones and if it fits into Note2, then why note on Note1?

That's called an mhl adapter. The port in the phone is micro usb, so the signal is converted to hdmi.

[Q] Samsung smart dock on Xperia z1?

Hey guys,
I was looking at the Samsung smart dock :
( can't insert link as I am a new Member)
And was wondering if it would work on the Xperia z1?
I know that the z1 supports MHL and OTG so I'm guessing it could work..
Also, I realise that the actual phone won't fit onto the dock properly but I really want hdmi out with at least 2 usb inputs, so I'm fine with using a micro usb male to female cable to run from the phone onto the dock.
This is my first post so let me know if I'm doing something wrong
Thanks in advance

It's a hardware issue actually, Samsung uses special usb connectors which can active both mhl and usb at the same time, not sure Sony does too...

I use something like this and it works fine to have HDMI out, but never tried using the USB in at the same time.

You can use the usb as storage or only for charging while using hdmi?

I heard that the USB input on that could only be used for power and nothing else.. :/

I think that's correct, as the HDMI output does not work unless there is AC power going to the Micro USB in.

Theres a cheaper version of the dock on ebay for $11 which has HDMI and USB (both full size) ports. I might buy it and try that one first.

A stupid question, how can I use the MHL cable and charge the Z1 in the same time? It is possible?
