Tab A7 charging + keyboard - Samsung Galaxy Tab A series Questions & Answers

I bought a Type-C hub ( https://www.klick.ee/swissten-usb-c-hub-8in1-with-3x-usb-3-0 ) and it works perfectly with my Samsung Galaxy S20, I can charge my phone and keyboard is also working.
But my Samsung Galaxy Tab A7 (2020) doesn't want to charge with it (keyboard and mouse are working when adapter is not attached).
Any ideas why this happening and how to make it work? What tablet can you advise to me which support OTG+Charging?

MHL 2.0 and OTG together

Hi All,
I am using Samsung Galaxy Note 3. I bought MHL 2.0 and OTG cables.
Both are working fine, if it is used separately.
Meaning, connecting MHL cable to T.V's HDMI for watching movies, videos in bigger screen is superb.
Similiarly, connecting OTG for external thumb drive, keyboard and mouse are nice feature.
I want to use both MHL and OTG cable (wireless keyboard / mouse USB dongle connected to OTG), so that I can watch it in TV and also use mouse and keyboard. I have tried the below options:
Option1:
Connected MHL to TV and Note 3. In MHL we have micro USB for power but for Note 3, MHL don't need the separate power supply and so I have tried connecting OTG to the MHL power, but it is not detected
Option 2:
I have googled and came to know Samsung Smart Hub Dock, but it says not compatiable for Note 3 and S5
Option 3:
Googled more and got this "VicTsing® Multi-functional 3 in 1 Connection Kit USB OTG" but unfortunately this also mentioned not supported to use both MHL and OTG at the same time.
Week back only I have bought new wireless keyboard and mouse for $90 and don't want to spend again in buying bluetooth keyboard and mouse which would cost (more than $150)
Any suggestions on how to connect MHL (for HDMI) and OTG(for connecting wireless keyboard/mouse) at the same time
I can offer you some work arounds. I personally use BT mouse and keyboard. (BTW a kind of stupid oversight I use microsoft sculpt bt mouse that I remember specifically states on the box full android functionality not that I cared at the time, anyway when only the mouse is connected I cant get the on screen keyboard to work as if the mouse HID is recodnized as both)
there are more then a few software sollutions involving sharing HID via Wifi through your pc and router or computer to phone BT connection. or aby tablet as remote on screen HID but I think having a good cheap BT set near by is generally usefull for more then a few things so I do believe its worth the one time spending.
On another note I couldent figure out if Samsung has a Multimedia Dock Specifically for Note 3 since it would be more then ideal

There is one that works
See this thread. http://forum.xda-developers.com/galaxy-s3/accessories/mhl-usb-otg-t1741583/page22
SKU: 238273 on DealExtreme DX.com
That is the one I have and the same one "brb8two" mentions in comment #217.
It works perfect with my S4 and also works with my Wireless Xbox receiver, but it is MHL 1.0 which I believe is NOT a full 60frames or whatever, so it may appear slightly laggy but not bad and definitley better than the Samsung hub option for $99.
If you come across one with MHL 2.0 please let me know. Haven't been able to find one yet.

[Q] Wireless Charging Possible on SAMSUNG Galaxy Tab4 10.1 WiFi ?

Hello to All,
I was wondering if any solution is available to wirelessly charge the SAMSUNG Galaxy Tab 4 10.1 WiFi 16gb version?
This is for someone I know who finds it very difficult to plug the cable in to charge. So if you know of any solution at all, please share it.
Thanks in Advance.
You have a USB qi with charging module? Qi charging pad? Pretty straight forward. Of course you'll need to have access to your USB port and it will then be blocked.

Simultaneous use of OTG and mhl

Greetings,
How can I get simultaneous use of OTG and mhl to work on my S5? SM-G900I
Thanks!
I have the Samsung Smart Dock, which provides that and works with the Note 4 (and some earlier Notes and Galaxy S). The water resistant port cover stops me from trying it with the S5 though, and I don't want to take that off right now. Unfortunately it's not easy to get an extension cable to try it either, due to the custom pin layout used for MHL on the S3 onwards.
@arghness thanks for the input - I found conflicting feedback saying it doesn't work with the S5. what is the model number for the smart dock you have? I'd really appreciate if you could give it a go

Samsung Smart Dock EDD-S20JWE, EDD-S20KWK, EDD-S20JWEGSTA, EDD-S20EWEG, EDD-S20EWE,
There are quite a few model number associated with this dock
Compatible with the Galaxy Note II, Galaxy S4, and Galaxy Mega (Not compatible with Galaxy Note 3 or Galaxy S 5)
Ah, okay. There are definitely posts (and videos) of it working with a Note 4 and I've actually had mine working with a Note 3.
On my S5, I can't even get the dock far enough in to the port for charging, due to the port protecting flap. Even without that, it might be an issue because the port is recessed in to the body so that the flap is flush with the outside of the case.
I still get the feeling that all the support is still there, if we could get a working extension cable. There's this: http://www.usbfirewire.com/Parts/rr-mhl-ext-xxg.html but I've heard that it doesn't even work properly with Note 2 (from an XDA post).
You're probably out of luck, sorry. I was hoping to be able to get it working as well.
hmm..okay, i've bought the smart dock, will give it a go when it arrives

It looks like the S5 does not support simultaneous use of OTG and MHL as samsung implemented a 5-pin mini usb connector. Unlike the S 3/4 and note 2/3/4 where 11-pins mini usb connector enable simultaneous use of OTG and MHL. I don't understand why Samsung downgraded the S5.

So there's really no way to unlock this phone with broken screen then right?

I don't think it is possible

Samsung probably downgrade S5 to a standard 5-pin micro usb connector to ensure broad compatibility with mhl adapater - this also prevented simultaneous use of OTG and mhl since in a 5 pins usb connector the same signalling wires are use for both mhl and usb-otg.
the S5 implement micro usb 3.0, I'm wondering if there is any adapter out there that can convert this into a 11-pin micro usb 2.0 connector??

That post doesn't say that MHL/OTG isn't possible with the S5, it doesn't mention the S5 at all. The pages I've seen seem to indicate that it's still 11 pin:
https://www.google.co.uk/search?q=s5+11+pin&oq=s5+11+pin
And other pages indicate that it can do MHL and have power, but that power is optional, unlike the S3:
http://blog.clove.co.uk/2014/02/05/mhl-adapter-samsung-galaxy-need/
They don't say whether OTG can be done concurrently, though, but I don't see why not.
I have a "11pin mhl v1.0 to hdmi adapter cable" that works fine with mirroring my S5 (SM-G900I lollipop) to an HDMI Display (Monitor or TV). The cable doesn't have usb input to test otg at the same time though. This cable also charges my S5 while mirroring.
I am interested in using my S5 as a desktop pc so would like to know if any one has had success with mirroring thier S5 on a TV/Monitor and using a Mouse & Keyboard at the same time!!!
TIA
any updates? Have someone found an adapter that does mhl and otg at the same time.... I have tried one adapter that does not work and asks several sellers on ebay about other adapters and all said either they don't know or it does not work simultaneously....
No adapter but you can use samsung sidesync between phone and pc.
sidesync? I want to convert my phone into a desktop/tv box and I don't want to use bluetooth
sidesync converts your phone in to an android pc using your pc's monitor,mouse,keyboard through usb cable or wifi. Your phone will display on the monitor like screen mirroring and you use your pc's mouse and keyboard to navigate and type.
sidesync wont work with tv because you need to install sidesync on pc.
ah ok thx interesting but it defeats the purpose of autonomy

Samsung Galaxy Tab A 8.0 OTG + Charging

I am looking to getting a tab a 8.0 for a car setup to replace my nexus 7. My main concern is the tablets ability to charge while using otg. I need the tablet to have USB audio out to a sound processor and also change the tablet.
Samsung website says it does otg + charging however I tried in a store and it not work - I'm thinking maybe it's down to the tablet being in retail mode?
Any info Is appreciated

HML? Samsung tab A 8.4

So i got a Samsung tab A 8.4 (SM-T307U) and i"m trying to plug it into a TV via USB-c to HDMI adapter. When i got it the guy told me it was possible. But now later I found out after talking with Samsung that its not possible because there it's not supported, no HML operation.
Is there any third party software/drivers I can't download so i could use a USB-c to HDMI adapter?
(Wasn't sure where was the best place to post this couldn't find the tab a 8.4)
Thanks Blair
