I can't seem to get video to play on TV with HDMI from the S3.
I bought an aftermarket HDMI on eBay and I plug it in while video playing and nothing happens.
Do I need a Samsung specific cable? Or any tips?
Thanks

So, I also had a similar issue recently. I bought one by Skiva that came up in an S3 search. Turns out, works for Galaxy S, S2, but not S3. The S3 uses a different interface for MHL than the previous S models.
I eventually caved and dropped $30 on a Samsung S3 -> HDMI adapter. Adapters to make it function with legacy MHL interfaces are available, I believe. Just make sure they claim (and are reputable about it) working with the S3.
EDIT: Also, if your tv's HDMI interface isn't "HDCP Compatible" (recent TV's use a handshaking protocol for basically DRM) it will either receive no signal or a black screen, and the device will claim it is outputting video normally.
Which adapter did you buy?
As sworld pointed out, the S3 uses a different MHL setup than older phones. It uses an 11-pin connector, where the standard 5 USB pins remain for USB, but deeper inside the S3's connector are 6 more pins to be used with MHL.
If the adapter you bought only has 5 pins then you'll need to buy an 11-pin to 5-pin adapter. Then your MHL adapter will work.
Samsung's new flagship device, the Galaxy S4 is the first phone to support the MHL 2.0 standard, meaning that HDTVs and monitors with such a port can charge the device and stream Full HD content down from it at once.
This adapter allows you to connect your Samsung Galaxy S4 with any standard HDMI video cabled so you can share what is on your S4's screen with other HDMI enabled visual equipment, like a monitor or TV.
This is perfect for sharing photos with family or friends or giving a presentation to a client.
The HDMI adpater uses the MHL 2.0 standard meaning the device does not need a power supply and it supports 1080p!
Just plug the microUSB/MHL connector into the S4 and then connect a standard HDMI cable to the adapter and to the TV or monitor, then the phones display will be shown on the big screen!
Samsung Galaxy S4 HDTV Adapter Features
This is an official accessory for the Samsung Galaxy S4
Allows for HDMI output to HDTV
Uses MHL 2.0 standard so the S4 does not require a power supply to work

Hello All,
I'm a new owner of a Galaxy S6 Edge, coming from a S4.
I had a Samsung multimedia dock for my S4, that had 3 USB ports, a HDMI Out port and a 3.5mm audio Out port. I purchased a wireless keyboard / track pad and plugged it into one of the USB ports on the dock to make typing texts & navigating the phone easier while at my desk.
Unfortunately, the male micro-USB plug on the Samsung multimedia dock does not fit the micro-USB port on my S6, rendering my wireless USB keyboard useless.
I've looked all over the internet and can't seem to find a similar docking station for the S6. Does anyone know of a docking station that has USB ports that will work with my USB wireless dongle & keyboard?
Much appreciated!
Hi,
Thanks for your report. It seems strange to me that the S6 micro USB port is different, should be the same old 11 pin that the Samsung used. Stupid question, but did you try inserting it the other way around, with the phone back facing you?
For your exact problem, with the keyboard, I assume the old USB On The Go adapter will work on S6, same as it does on S4, S3, Note2, etc. It's this one: http://www.samsung.com/us/mobile/cell-phones-accessories/ET-R205UBEGSTA .
There's also a HDMI adapter, http://www.samsung.com/de/consumer/mobile-devices/accessories/connectivity/EE-HN910FWEGWW. Maybe those 2 can be combined, instead of using the dock.

Thanks for the reply!
Way ahead of ya on making sure the micro-USB plug on the docking station is facing the right direction. I tried docking it backwards and the plug n' port absolutely do not fit that way. It's facing the right direction, just that the port on the S6 is not able to accept the plug on the docking station....despite both being Micro-USB. I did notice, however, that the plug on the docking station had two small grooves indented in it, that looked different than any other standard micro-USB cable plug. It could be that those indentions made the device proprietary to the Samsung range of phones that released during the S3 / S4 years (including the Note 2 & 3). If you look at the compatibility of that docking station on Samsung's website, you'll notice that only the S3, S4, Note 2 & Note 3 come up.
I suppose the USB dongle you linked could work, but reading the device laying down flat, while trying to type on the keyboard might be problematic. You'd think that someone would make a universal micro-USB docking station with USB ports...but I haven't been able to find it.
I'm pretty sure the S6 no longer supports MHL which probably explains why the dock doesn't work either.
You can still go USB OTG, which should let you use your keyboard and trackpad mouse devices.

Interesting.....so are you saying that the micro-USB male plug on the Samsung docking station also had MHL connectivity integrated in it, which is why it's form factor is slightly different than a standard micro-USB plug?
The only times I've ever seen a MHL port on mobile devices was as a separate, similar looking, but different port than the micro-USB port.
I supposed all the wireless mirroring tech out now makes including hardware mirroring functionality not needed.

That's correct, it has to since it offers an HDMI out on the dock.

You're also probably right in your assumption that MHL isn't really needed anymore due to the widespread wireless screen mirroring technologies.
I'm looking for devices (Android tablets) which supports OTG (to connect slave-devices, e.g., a mouse) and charging at the same time
There was a thread about Nexus 7 https://forum.xda-developers.com/tab-s2/help/usb-otg-charge-t3588019
It needed a custom kernel to get OTG+Charging working
But it's very old, you can't buy a new Nexus 7 anymore
Also someone mentioned about Samsung tablets:
Samsung tablets for sure can support OTG Host/Charge for a tablet and peripherals. Here is a list of supported tablets:
Samsung Galaxy Tab A (10.1″)***
Samsung Galaxy Tab S2 (8.0″, 9.7″)
Samsung Galaxy Tab E (9.6″)*
Samsung Galaxy Tab A (8.0″, 9.7″**)
Samsung Galaxy Tab 4 (8.0″, 10.1″)
Samsung Galaxy Tab S (8.4″, 10.5″)
Samsung Galaxy Tab Pro (10.1″, 12.2″)

But these devices are also quite also and Samsung devices aren't that cheap anyway (if buying a new model)
So... Are there any devices (on sale) with normal prices which support OTG and Charging at the same time?
It doesn't matter if there is one port (input) or two (one for OTG and one for charging). Some Windows based tablets has a separate port for charging
Does Samsung Galaxy Tab A 7.0 (quite cheap) support OTG+Charging at the same time?

What you need is a "powered USB hub", it has its own power supply and it will allow you to connect multiple USB devices(mouse, keyboard, flash drive, etc..) and charge the device at the same time by connecting your phone charger to the hub at the same time.
I use a USB to microUSB adapter, then connect the adapter to a USB hub that has 4 ports, then I use the adapter to connect the hub to the charging port on the device, then I connect a keyboard, mouse and phone charger to the USB hub.

There is no such hub... At least officially. You won't find much. I saw one hub, but users said it was working only with Windows tablet (OTG+Charging), for Android OTG was working only
just google "Android OTG+Charging" you you'll it's quite a problem

Something like this won't do the job?

Or this:
https://www.amazon.com/dp/B00VK9C24M/ref=cm_sw_su_dp
Of course, the device must support OTG and the accessory charging feature. If it doesn't, I'm not sure there is anything you can do to force it.

You have to test first
Does this hub supply a tablet with power or connected devices (slaves) to tablet? I need to charge a tablet and not connected devices (connected devices can get power from tablet)

Well... manufactures don't give any information if their devices support all of this and what customers have to do to get it working (buy a specific hub or something else)
It's been two days and I only got reply from you. So we can say that it's not that easy and we can't be sure what to buy. I don't want to waste money if it's not going to work
Would be great if someone could really tell me which devices (tablets) support this feature, which hub should I get for such devices and so on
Did u have any luck with this?
I am looking for the same thing. So far I tested a fire 7 that did not work.
It seems like usb c tablets might be the answer. Seen a post that mentioned a version of the note working this way.
I might give the galaxy tab a8 a try.
I'm building a list of those known to work and not work: I can't post the link.
So far, these devices are known to support USB OTG and charging with an ACA cable:
RaspBerry Pi
Amazon FireStick
Amazon Kindle Fire 10???
Dell Venue 8 pro
HTC One M9
Lenovo Miix 2 tablet?
Lenovo Yoga Book
Moto G 4?
NuVision Tab 8 (Windows 10) after restart only?
Nvidia Shield K1 table??
OnePlus One
Samsung Galaxy S3
Samsung Galaxy S4
Samsung Galaxy S5
Samsung Galaxy Note 3
Samsung Galaxy Tab 4
Samsung Galaxy Tab A7?
Samsung Galaxy Tab A8.0
Samsung Galaxy Tab E?
Samsung Galaxy Tab S2??
Samsung Galaxy Tab S 10.5?
Samsung Galaxy View
Snes Classic
Devices which have a separate DC in power jack and support USB OTG (WIth any OTG cable, does't need ACA)
iRola 7" tablet. Very old.
E-Ceros Create 2 Tablet. Old
Ainol Q88. A newer version of this with Android7.1 and 1GB RAM is apparently still made. $53 It's said to support USB OTG (at least for a 3G adapter) and pictures clearly show a DC power jack, although the adapter may not be included. It is typically sold as a childs toy, but the protective rubber covering peels off to reveal a black plastic case.
Cube Talk 11 3G Phablet $85?
Raspberry Pi
Known to support OTG but NOT while charging: This limits OTG to either very short periods of use
Amazon Kindle Fire 7
Asus T100TAM
LG Nexus 5
LG Nexus 7
Samsung Galaxy Note 4
Samsung Galaxy S7
Samsung Galaxy S8+
Samsung Galaxy S9
Samsung Galaxy TabPro 10.1

Thanks for the summary. I am also looking for android tablets that support USB host and charging at the same. A few old tablets from LG and ZTE have both micro-USB as charging port and a full-sized USB port to host other devices. But they are quite old. So ACA cable might be the way to go.
Question: Do we need to patch android os as described here use ACA cable?
"You can lead a horse to water, but you can't make it drink."
You can always offer power to a hosting device.
Whether it takes it is another question.
If it's rooted you may find that you can control something to make it take it.
I've used back-powering hubs to power Androids.
This is a hub that has been modified to present power on the upstream port.
You can modify any powered hub to do this.
See: https://forum.xda-developers.com/showpost.php?p=25639514&postcount=8
Has anyone come up with any solutions to this problem? I see this thread is a year old but I am here with a samsung tab A 8.0 2019, I have the exact same problem. I need to an external usb in service while charging, not one or the other.
The use of a specific value resistor on the USB OTG ID pin to ground is pretty manufacturer specific.
Some devices have up to a 5 bit non-linear converter on the ID pin to give up to 32 modes.
I've found Samsung to be a fan of using the OTG ID pin.
I would definitely try values from short to 1 k to 1 M (in an exponential progression).
I don't even remember which device this is, but it gives you some idea of the values they might use:
Code:
0
2000
2604
3208
4014
4820
6030
8030
10030
12030
14460
17260
20500
24070
28700
34000
40200
49900
64900
80700
102000
121000
150000
200000
255000
301000
365000
442000
523000
619000
1000000
Open
If you're rooted you may be able to control the charge controller directly.
Some of this could be a pain if you were plugging/unplugging all the time.
If this is some hard-wired, fixed usage you could definitely hard wire your own 4 V charger into the battery.
You might try getting a few pots 10k, 50k, 250k and some 220k resistors to try your luck.
Whoever is reading this I can assure you that the Samsung tab A does not charge while OTG. Jamming a resistor in there to short out the sense pin is not a thing. These are pwm charging and have been for a while. Even after spending $100 on the OTG cable alone it's still not working.. rooting.. twrp.. none of It makes any difference at all

How do you even do that? An OTG adapter is < $5. A connector is < $1.
OTG adapters normally have the ID grounded right inside the connector so you can't use that unless you chop up the connector.
You need to make up your own micro USB connector.

I don't have a Samsung Tab A so there's only so much that I can say.
All devices have a linear or DC buck converter that feeds USB power to the battery.
All devices (that do powered OTG) have a charge pump or a DC boost converter that feeds power to the USB jack.
Both of these are under control of the processor.
Look in your kernel source under usb/otg
You should easily be able to see if you have an ADC on your OTG ID pin or if it's just a GPIO.
Look at your device under /sys and see if there is anything suspicious with "adc" in its name.
Code:
find /sys -name '*adc*' 2>/dev/null
In worst case you'd have to modify a driver.

Woe woe woe!!! I had fully given up on this tablet and didn't check back here out of anger and frustration. I have a hard time getting any support.
I am having a hard time following your technical speak. How do I get into that menu? Are you willing to give me a hand with this? Those commands look like ADB??
The charger I purchased was from a company called "lava" you can find them easily online. It was a Y cable that was almost $100. It didn't work.
Hello,
What is a good hub for a Galaxy S8+ tablet? I want to get a hub to get the external interfaces such as HDMI, usb, etc. I contacted Anker about this and they have not tested their hubs on the Galaxy S8+ tablet. So what is a good hub?

Honestly, any hub should potentially work - the USB-C standard supports HDMI as well as Ethernet, and a high end device such as the Tab S8+ should have little issue. Anker is a pretty solid budget brand.
