OTG not working? - T-Mobile Samsung Galaxy Note 8 Questions & Answers

OK, so I finally decided to try out the OTG adapter that came in the box, and lo and behold nothing I plugged in to it worked.
Nothing was recognized, keyboard, mouse, ps4 controller, 2 different thumb drives. Not a thing from the phone, nor the peripherals, the thumb drives should have lit up, the ps4 controller as well.
At first I thought maybe it was a faulty OTG adapter, but I pulled out my wife's note 8 box and tried that as well. Same results. I've tried Google searching the problem and the threads I have found have been resolved by unrooting the phone. My phone is NOT rooted. My next step will be to factory reset the phone and see where that takes me. Won't be able to do it for a day or two though, so if anyone has any ideas before I factory reset I'd really appreciate it.
TIA

are you using a case by any chance? i have issues with mine using any type of case. it needs to be plugged in as much as possible. hope this helps

Have you tried rebooting. A lot of people have found that after attaching stuff to the dock for the first time it didn't work, but they rebooted it and it worked for them. Something about the dock did an update.
Thanx for that info but i have tried rebooting several times with the dock and USB connected and without the USB connected. But what explains the reason for my ps3 controller not working? ( My dock version is " TF201-DOCK-0206 " ----if that helps at all. )
That's what mine is at and I use my PS3 controller just fine. Have you tried hitting the center button on the controller. I know I was having problems as well until I hit that button. You know it works if the screen that you are on goes back to the home screen.
OMW!!!!!!!!!! WHAT ARE THE CHANCES.....!!! while i was replying i decided to plug my external and it worked!!!! my ps3 controller too!!!! Ive been trying this whole day to get them to work and out of the blue they work lol! thanx again for all for help anyway!!
No problem. Hopefully this helps others out as well.

[Q] Prime wont detect mini HDMI cable

Suddenly my tablet has stopped detecting mini HDMI cable. I dont know what to do?
It was working fine 2 days ago. I even performed full factory reset on the tablet but still it doesnt detect. The cable is good, i checked it by connecting my phone to it. Please Help
Thanks,
You could have possibly busted the jack in the tab, its pretty fragile if bent around, also try very carefully flexing the connector around when plugged into the tablet. Sometimes connectors don't fit in as snugly as they should, therefore not making a good connection. Just make sure not to break the jack if you haven't already.
Well not sure if i broke it or not. But i tried many things like resetting the tablet, restarting etc. but still it wont detect the HDMI cable.

Samsung Multimedia dock not displaying HDMI.

Hi, I was hoping someone could help me please.
I recently purchased Samsung's smart dock to use with my note 3. It goes into dock mode when i sit the phone in the dock and i can control the phone using a wireless keyboard and mouse so the dock seems to be working as it should. Ive tried 2 hdmi cables on all 3 sockets on my panasonic viesa tv. I just cant get a picture on the tv.
I have tried all the obvious reboots, checking connections etc.
I can't see what the fault may be and I don't have another screen with hdmi input to test it with.
any advice would be appreciated.
Thanks
Did you plug in your power supply?
Yeah, plugged into power socket using all official Samsung cables plugs etc. It's driving me mad. I'm going to try it on a friends TV tonight. Hopefully it's just a compatability issue with my TV. But I use the hdmi inputs with other several other things as well without problems.
my note 3 is rooted on a tw rom.
So I tried a Samsung brand TV. Still no picture, so I installed stock firmware and tried again. Still nothing, so I guess I have a faulty smart dock or I have damaged my port on my phone. (It charges and transfers data fine without any problems).
I shall be exchanging the dock, but if that does not sort it I guess it's the port. If it's the port then I've voided my warranty by setting knox to 0x1.
Does anyone know how I would be able to test it, because it doesn't seem damaged to me.

HDMI Cable

I purchased the Amazon Basics micro HDMI cable (http://www.amazon.com/AmazonBasics-High-Speed-Mini-HDMI-Cable-Ethernet/dp/B003ES5ZR8/ref=sr_1_1?ie=UTF8&qid=1419968500&sr=8-1&keywords=mini+hdmi) and I've been having issues with poor or no connection. The first time I connected the tablet everything was great. I played about an hour of Portal with no issue. I had to reboot the tablet, and after that I couldn't get a signal. I tried the HDMI cable in my Canon 70d and had no signal. I assumed that the cord was bad, but last night I tried again and got a good signal for about ten minutes. I had to change the source on the TV and when I went back to the original input, my signal was gone. Has anyone else experienced this with the Amazon HDMI cable or any other HDMI cable? What are some good low-cost HDMI cables that others have had success with?
Ive used this adapter a few times without issue. http://www.amazon.com/gp/product/B00IZYIYX8/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1 .. If the cable is giving you an issue with multiple devices can it be the TV?

I plugged the cable into all of the HDMI ports on the TV and one on my Sony receiver. It seems to react the same way with both devices. But that adapted you linked looks pretty slick.
Sounds more like a bad cable than anything else. If you replace the cable and it continues then the shield would be the next more likely culprit. I haven't heard of this happening to anyone else, though.

Galaxy S8 HDMI not working

I bought the ADAM elements CASA H01 USB Type-C to HDMI Adapter Gold, I tried connecting HDMI to my S8, S8 says HDMI connected but the TV has no response. I am sure the TV works with HDMI as I tested my XBOX on it. Is there anyway to make it work? Or is my adapter broken?
you can try things like switching the tv off/on and the phone off/on whilst its connected. sometimes, not often, that will help
it sounds like hdmi handshake issues. basically a compatibility problem between the phone and the tv.
Thank you for the suggestion, I tried but still doesn't work. If it's a problem between the phone and tv, should I try the adapter on other tv?
I used Choetech USB C to HDMI 60HZ cable to my S8. Everything worked well. https://www.amazon.com/CHOETECH-Thunderbolt-Compatible-MacBook-ChromeBook/dp/B06XP9NV4G/ref=sr_1_5?ie=UTF8&qid=1495422430&sr=8-5&keywords=choetech+HDMI
I had some HDCP issues when I tried connecting my S8 to a capture device, but that was due to a poor quality cable.
Make sure your device can read the HDMI signal coming from the phone too. It appears to send 1080p or higher, so if your device only understands 720p (some smaller TVs are like this) it might not be able to see the signal from your phone.
I'm having same issue hubbies works mine won't same cord and tv???
Any idea what's going on I just factory reset my phone and still doesn't work
I just got an hdmi to USB c adapter today as well and I first connected it it did not recognize my phone either. The thing that seamed to do the trick was attaching the adapter to my phone first without the hdmi or power cord, then powercord then connecting the hdmi cord and all works well
still not repaired
4 repair invoices 3 months and still not repaired currently on hold with Samsung .... i'm not impressed as this feature was a huge decision for buying the S8+
i use baseus usb-c to hdmi cable - all work good (but no dex)
I have tried two different usb-c to HDMI cable adapters and can't get neither of them to work. Any ideas thanks
Broken and need help
I have a Ugreen Adapter for usb-c to HDMI cable, it worked very well
On several tvs, it WAS working here in Mexico on my ATVIO tv, then I did some phone cleanup and it STOPPED, is there a special application or setting that I've uninstalled????, I'm lost without YouTube on my tv LOL , cant find info anywhere and I swear I installed something on my phone to get it working like 7 months ago in Dallas LOL
biggest thing iv found with EVERY usb type C connectivity issue, POCKET LINT. its as simple as using a sewing needle or safety pin to CAREFULLY take the pocket lint out of the type C port on your device, there are 30 individual pins in there, and they ALL need to make a good connection to your adapter. brand does not matter, if it works with phone A phone B will figure it out (unless your phone simply doesnt support mhl adapters)
Same problem - Galaxy S8+ with Choetech USB-C to HDMI adapter. Worked a couple of months ago not working now. Wife's phone (exactly the same) work a with adapter and HDMI cable. Cleaned, powered on/off, reset phone, nothing works. So frustrating. Any ideas?
I was using my S8+ with my TV. After a couple updates ( prior to Pie) no longer worked. Please don't suggest turning things on / off or factory reset.... The cord is fine. My phone just now updated to Pie, I thought great, maybe it will work again..... nope... I've contacted Samsung, same BS runaround. Samsung - must be a compatibility issue, Me - it was working, Samsung - must be the cord, buy a new one, Me - already did, tried two different brands, Samsung - was one of them Samsung, Me - ......., Samsung - try factory reset, Me -....... by this time I know I'm screwed. There WAS something to do with an update. (And yes prior to the Pie update I did a factory re-set with no results). From the comments on this post appears no one has a solution....
