[Q] [10.1][8.9][7.7]Multi Accesory Solution for Galaxy Tab

Hello Everyone,
As everyone know our beloved Galaxy Tab only have one port, that is used for HDMI, Charging, and USB functions.
I was wondering, is there some kind of adapter(s) that let me connect my tab to my HDMI TV, while accesing some USB memory stick and charging at the same time?
I'm looking forward for this solution because I want to connect an external hard drive to see some videos on my TV while charging the Tab.
In worst case, at least connect my tab to the TV and access the external USB hard drive.
Thanks in advanced.
The closest thing to a multiple accessory solution for the Galaxy Tab 10.1 that I could find is this SD-card and USB adapter. I am also hunting for a something that will do HDMI/USB/SD card in one attachment.
I'm trying to build sleeker external storage by combining the official USB adapter with either a tiny 16GB flash drive or a tiny USB microSD card reader combined with a 16GB microSD card.
Has anyone used this combination, or something similar, with the 10.1?
I saw the Official HDMI adapter for galaxy tab 10.1 8.9 7.7 , it has an extra port for charging (in fact, it only works while charging) , if we could find a USB Hub that can charge the tab at the same time, maybe it could work.
If there's interest in a DIY solution I might be able to cook up a quick PCB that would fit in an Altoids tin to do it. I'd be glad to release it on BatchPCB (http://batchpcb.com) or package it up for a FusionPCB run at SeeedStudios as an open source design with a digikey/mouser/arrow BOM if there's a preference.

[Q] Question about USB Flex cable Tmobile GS2

Hello to all!!
I recently brought a Tmobile Galaxy S II "SGH-T989". Now, this phone has a bad USB port / Flex cable. I'm pulling my hair out trying to find the part on the internet but all I can find if the USB Flex cable for the SamSung Galaxy S2 II "i9100" and not the "SGH-T989". Does anybody out there know if the i9100 USB Flex cable is compatible with the SGH-T989 phone? And if not, then where the heck can I buy the USB Flex Cable for my phone.
I'm sure this is a noob question and I'm sorry about that. But any help I can get will be very much appreciated.
It should be the same Samsung cable and charging cube for any of the Galaxy S2's including the Sprint and ATT version.

Awesome!!
Thanks for the reply. I ordered the part on Ebay. The seller believes it won't work but the part was only $10. So what the heck? Why not give it a try!! Again, thx for the reply.
No problem. My wife just got her Tmobile GS2. The charger cube and cable are exactly the same as the one that came with my Sprint Epic 4g Touch. You are smart that you bought the factory OEM cable because the aftermarket ones you can buy for 2 bucks are junk.

He means the flex cable that connect the USB port of the phone to the motherboard of the phone. Not the actual USB cable.
Doesn't look like there is an actual cable connecting the port to the motherboard. Looks like it's soldered directly on the board. Link for part: http://www.wirelesspartsinc.com/samsungt959a687i9000epici897chargingport-6.aspx
The part I'm talking about is the "Dock Connector Charging Port Flex Cable for SamSung Galaxy S2". I googled, ebay'd, etc, etc and only found the part for the i9100. I tried to reply with a pic but the website won't let me post outside links until I post 10 times. Sorry.
Any thoughts?

Yeah, I can't see any references to the analogous part for the SGH-T989 either. The disassembly video I found on YT didn't get far enough to see that cable either so I got nothing for ya. I don't know why they would use a different part though considering the phones are so similar. Best of luck.
update?

[Q] Note II MHL > HDMI issues

Hi all.
I've searched for similar questions and can't find anything that gives me an answer... so here goes.
Model number: GT-N7100 (Samsung Galaxy Note 2)
Android version: 4.1.1
Modifications: None.
Problem:
- Connect MHL cable to phone.
- Connect power
- Connect HDMI to tv & MHL
- Phone pops up a message on screen advising that HDMI connection has been made.
- No output from phone to tv.
I tried originally with the wrong MHL cable designed for a Galaxy S2 (established this thanks to a post I found on here, thanks). Then replaced with one designed for the S3 which should (according to what i read) also work with the Note2.
Am I missing something here?
The cable used was from Amazon and is not a samsung original part. But before spending more money to get the samsung part i want to be sure i exhausted all options with the cheaper alternative.
Thanks in advance for any help anyone can give.

my theory is it has something to do with all share cast
I bought a 'generic' adapter at first, did not work. Ended up going with the Samsung adapter...worked fine...
make sure yr MHL cable/adaptor is compatible for note2/s3, they use different pins with older model
Hi all.
Thanks for the replies. [will do the whole thanks button thing in a minute].
I threw the adapter in a drawer for the weekend and pulled it back out this morning to have another crack at it.
Its the cheap n nasty adapter that is at fault. I shoved the connector into the bottom of the phone really hard this time, and instead of black, the tv screen went green. All green. A bit of jiggling later and i had phone output on the tv, but its a very sketchy connection and a slight knock loses the connection, even though the phone still thinks the cable is connected still.
Only problem then is that there is no audio coming through the tv. All phone settings suggest there should be.
So i went upstairs to try on another tv, and it works perfectly with video and audio (once the cable is rammed home good and hard).
Problem solved. For now, it will do. But I will at some point be investing in the genuine samsung part that should do the job properly. And a new TV for the living room ~ current one is old and was a budget model at the time, so you can imagine how bad it is by todays standards.
Hi, can you help to check if the camera apps work when you use mhl ?
Im using the sprint gn2 do I go with the same step when connecting mhl adapter? Before you connect to television is the phone suppose to be charging? I think I have to buy the right one .I bought mine amazon from china and still have not hooked it up to my tv yet. Can there be a problem with phone? Its new never dropped

i just got my samsung MHL adapter which is for the S3 but supposedly should work with note 2 also.
when i connect the hdmi cable and the power cable and then connect it to my phone i see a popup "hdmi cable cvonnected"
however,
my monitor (Dell 2408WFP) just goes into sleep mode.
i also tried another monitor.. same thing.
i'm on android revolution with perseus kernel... which is just a modded stockrom.
i have not made a samsung account so i don't have any of the samung specific apps activated... could this be the problem?
do you need to have that sharecast or whatever to be activated first in order to get the TV out functionality?
I bought Samsung MHL adapter last month for HTC One X and it works fine even without connect the phone to charging.
I just tried that to my new Note 2 and it doesn't work at all.. already try to charge the phone still not showing anything not even a notification saying my note2 connected to the hdmi...

Is it true with the note by sprint ...it has to be sprint o/s to work and can't have a rom on phone

Having the exact same issje with the original s3 adapter. It worked fine 2 days ago and then one day from another it magically stopped working on my note 2. Still works with other devices..
ok.. i decided to actually create a samsung account and installing the all-share cast app hoping this would finally make the mhl work..
but alas..
same thing..
i connect power, mhl en and hdmi cable.... set monitor to look for hdmi signal...
phone then gives me the 'hdmi adapter connected' message and then the monitor goes into energy saving mode...
i guess my adapter is faulty.... it is supposedly a genuine brand new samsung adapter but i got it from ebay hongkong or china or whatever... so... well... you know..
i think i will order the wireless all-share hub in stead...
Are you rooted? I've read that hml doesn't work if you are.
Edit: I should have read the rest of the thread. Looks like you solved the problem.

well yeah... if getting a wireless allshare cast hub instead for 80 bucks is a solution.. then yes.. i guess it's solved..
by the way,
yes.. i have root.. where did you read that a rooted phone prevents the MHL adapter from properly working?
do you have a link or something?
in that case i could still try to persuade the Android Revolution HD Rom developer to look into the issue...

Try it using the 5V - 2A charger, i have read, somewhere i forgot, that 2A is a must for being able to use MHL.
I can't say if it is true or not, i'm atill waiting all stuff be delivered (All-share cast hub, MHL adapter, Smart Dock, etc).
Good luck
It seems like the china products r all faulty

For me the MHL cable worked well with easy disconnections (any minimal movement). But I used it with the bloutooh mouse and so I didn't feel so much the issue.
Now the note 2 doesn't reveal the cable. I plug it in and nothing happens.
I don't remember if I changed ROM before the issue but it's sure I always had a custom ROM.
Can be a ROM problem?
I will try the MHL cable with my father's s3 and let you know if is a cable issue.
EDIT:
SORRY GUYS, IS A CAVE PROBLEM. ITS DEAD
I have rooted my device also. Come to think of it, this might just be the issue. Rooted with exynosabuse gonna try to unroot and see if it works. Still want it to work with root though because i use the sixaxis to play games..
Once u unrrot your note 2 did it work with the mhl cable

[Q] Note 1 OTG cable work on Note 2?

Just recently bought a Note 2 (GT-N7100 international version), and it's marvelous.
I just spent an hour searching this forum and can't find anything that addresses my question. It may be buried in here but never came up in my searches.
I have a bunch of OTG cables that I used with my Note 1 to read flash drives. When I plug in one of those OTG cables to my Note 2, it shows the cable being connected, but when I plug in a flash drive it doesn't show up anywhere. I tried many different flash drives with various amounts of data on them, but no joy.
I'm presuming that the Note 1 OTG cables won't work on the Note 2, but would like one of the wizards to confirm this before I include the cables in the Note 1 package that I'm getting ready to put on eBay.
Thanks in advance for any responses.
hey buddy it works, first time when you connect the cable and pen drive wait a minute and then restart your galaxy note 2 and then again connect the cable along with the same pen drive...
Genius! Worked like a champ. I never thought of that, and the Note 2 manual says nothing about that.
Thanks.
There is only one samsung otg cable which works with s2, note, s3, note 2. There are hdmi adapter different for s2, note and for s3 and note2
I've never needed the HDMI adapter, but that's good to know.
Thanks.
you can use an old mhl/hdmi with a note2, just buy a 11pin to 5 pin adapter off ebay for $3
if you get the metal adapter you can open it and use it to get access to the other pins too for modding..

Well, the obvious answer is that the cable is not the correct one. Was it in OEM Samsung packaging? Or did the seller claim that it works on SIII/Note 2? Lots of cables fit and will charge, but don't work for OTG because of the pin structure on the cable.

Have you try to check if the Power Saving Mode is enable? Try to disable it because the flash drive needs power to work. This is based on my experienced with my Note 2. I cannot get it to work at first and I found the culprit is the Power Saving Mode. So when I tried to disable it, then it reads my flash drive. Hope it helps..
Pen drive filesystem
What about the disk format? I have heard that only FAT and FAT32 partition are readable from OTG and not NTFS. Is it true?
I'm not sure whether that's right or not, but every file system should work with this app: play.google.com/store/apps/details?id=com.paragon.mounter

p5210 otg

so if my tab 3 10.1 picks up my usb keyboard otg is good to go right ?
i know the 7.0 won't and doesn't, but i also came across something odd
using a generic cable w/7.0 to transfer file from pc my tab [7.0] wouldn't register
as being connected or come up as malfunctioning but with the samsung cable no prob
the cable for the 10.1 is the same cable
so is the tab 7.0 an otg nogo or does it have more to do with the charger port ?
Tab 3 7.0 and Tab Tab 3 Lite have NO support for USB OTG. Because they ain't able to provide power to the external devices.
All you need is to build up your own USB OTG by tricking it to provide power to the external devices. That mean standard OTG won't work.
About Tab 3 8.0 and 10.1 no problem with them. The only thing I hated is they don't support xbox controller natively
