Hi guys, I'm new here so I apologise if this is in the wrong place (it seemed fitting...)
So I have a Galaxy Note 8 and I have recently learned that it has MHL capability. I thought oh that's great, I can now connect my phone to my car radio and mirror its screen. With this information in mind, I purchased the official Samsung usb-c to hdmi converter cable thingymajig.
I then ripped my radio out of my car, plugged in an hdmi cable and set it up. It worked flawlessly, except for the fact I had no handbrake cable fitted so I couldn't use the touchscreen. I got around that by fitting the wire and grounding it, but that's not the problem.
The next day when I connected it, my phone crashed and then gave me the moisture has been detected error. I thought maybe there was a tiny bit of moisture as it was pretty humid outside. After finally getting rid of the stupid error, it proceeded to do it every single time.
Yesterday I took my wireless charger down to my car and used this so it would at least charge it a little. I thought maybe the cable wasn't getting any power and needed a boost. It worked that time but when I tried again, I got the moisture detected error.
Since then, I've been getting it randomly. Sometimes it'll connect without a hitch and sometimes it's like no can't be arsed. I figure the problem is either with my phone or the radio because I can connect my phone using the same hdmi adapter to my TV and computer monitor without issues.
I have the Kenwood DNX525DAB head unit. It's a bit of an oldie but it does the job.
I'm just wondering what would cause it to give this moisture error sometimes? There shouldn't be moisture, it's hot right now (and I don't get that error when connecting to my TV and monitor).
Anyone have any ideas as this is driving me up the wall. Thanks in advance ?

Yesterday, I went to a car audio shop primarily to get an alarm installed and they said they would install a hardwire micro USB cable (that I purchased online and brought with me) for free while they were at it. It was to go to my N1 car dock. The install took all the way until closing time so the owner of the shop went over it with me and then everyone went home. It was late on a Friday and I didn't think to test the hardwire install. Probably wouldn't have mattered much then anyway.
This morning, I docked my phone and nothing happened. I originally thought it was a software error so I reflashed everything, still no luck. Then I swapped cables to the lighter socket and the phone docked/charged correctly - I should note that the dock worked fine before using the lighter socket cable. I plugged my phone into the hardwire USB and it started charging. I put the hardwire cable back into the dock and tried docking again multiple times. Nothing happened until right when I was about to go inside, I docked and saw the charging light come on and Car Home popped up.
I drove around for a bit and didn't lose docking once. This was all well until I had to come home to unload groceries and then go back out. After shutting off and restarting my car, I docked and nothing happened.
What I wanted to convey in this lengthy story is what is known right now. The dock paired with the lighter socket cable works fine. The hardwire cable charges my phone fine. The dock paired with the hardwire cable doesn't work 99% of the time.
To all the EE and circuit-savvy people, do you have any ideas as to what could be wrong? I called the shop owner's personal line today and he thinks it might be a loose connection somewhere. This was before I drove around, and after the normal bumps and things of driving and not losing dock, I don't think that's it. I tried jiggling the cable and making sure the USB connector fit properly; no dock. I don't think it's a faulty cable either because any time I plug it into my phone, it charges. Then again, I'm no expert on anything electrical-related so I could be missing something.
The shop offers a lifetime guarantee on install work so I'll be back Monday to have them check it out. The only bad thing is that since it's a hardwire install, the installer will have to pull dash panels to check things out and then I'll be stuck at the shop for however long it takes, which I'd like to avoid, so any troubleshooting brainstorm ideas I can pass along that might help will definitely be appreciated.
The cable I have is part # MFX5V-B-MICRO from mountguys (I can't post links yet) and if you need any more info from me to troubleshoot, I'll be happy to provide it.
I would actually venture to think its a voltage/ampage problem, which could be due to a loose connection, but is probably just because a line has been spliced too many times. Ie enough juice to charge a phone but not enough to power a dock.

Thanks for the input. Hopefully things will sort themselves out tomorrow.
I'll come back with an update after everything is solved in case anyone here is also curious as to what went wrong.
Wasn't a EE problem at all. One of the two protruding prongs on the male end was loose. Got a new cable for free and now all is well.
Hi
I just recieved my Adapter but something seems to be faulty on this,
when I connect it with several HDMI cables the mirrored picture starts to jitter or the connection break for a few seconds.
The cables are not decoupled and not really expensive, I have no other HDMI device to test them but I dont think that they are buggy.
The TV connected to is a Philips PFL8404
Some suggestions what I'm doing wrong?
The GT is rooted and on stock ROM.

i have the same issue. i tried two different hdmi cables and two different hdtvs and the issue is still happening. at this point i think its a defective adapter. Im gonna exhange it.
I had a similar issue back when I had a Xoom (which I ended up returning cause of weight). I am debating over ordering the adapter for my Tab, and if they are doing this, too, then I'd be fairly dissapointing. I always figured maybe the Xoom had a loose connection or the cable sucked, but maybe it's something else?
Got my HDMI adapter for my Galaxy Tab 10.1 yesterday also. It flickers and looses connection so much it useless. I've tried several new HDMI cables, and 3 different TVs. All flicker and blink. I'm sure it's a bad adapter. Will be returned shortly.
i would like to see someone post positive things about the hdmi adapter, have been thinking about getting one, but so far all these posts make me believe that its now worth it?
thanks
recieved a second adapter and still the same, seems to be a problem with the GT itselve or with some drivers build in, may the root crashed something, will trx out.
just ttryed another 40 bucks cable and still the same, dont think thats a hardware fault by the adapter. The only thing I can test now is to unroot to stock. Will test later and update.
UPDATE: Unrooting doesnt work
it doesnt seem like the people with the verizon hdmi adapter are having this issue. I wonder if its made differently?
I just received my adapter from Verizon and I can confirm the same issues so its not related to where you buy it.
Anyone notice what the status of their battery life is when using the adapter? Mine glitched the first time I tested it out and I had just taken the Tab off the charger. I kept getting a notification to unplug the Tab because it had reached 100% charge, which I haven't seen before. When I tried it later in the day it wasn't fully charged and it seemed fine. I haven't had a chance to try it longer than 10 minutes yet so not sure if its battery charging related. I know it doesn't work without a power supply so maybe once the Tabs at 100% it rejects power and cuts the HDMI off. Just a thought, I may be wrong.
I just tried it with 30% battery life and still having the same issue. does anyone have one that works?
Yeah I tried watching a movie on mine last night with about 70% battery and it switched from TV to Tab then back to TV about every 5 minutes.
I don't have an HDMI out cable, but I was wondering if you guys were plugging the charger into the HDMI, or if you were using it without it. I'm curious because I saw a review about it stating they needed the Charger to be plugged into the HDMI to get it to work.

yhea thats right you have to plug the wall charger in otherwhise it wont display anything at all, our problem is the faulty result whats on the screen
Wow. I was just about to order the HDMI adapter from Sammy (I stubbornly kept waiting for BestBuy or Verizon to get one in stock). But seeing all these problems, I wonder if they're having quality or other issues, and hence why it's not hitting shelves yet.
Does anyone have a feel for whether all seem to be defective, or if these posts are more representative of the adapters that are defective? (guessing from those saying they've tried more than one, that there seems to be a general problem with the adapters).
Okay I have a 10.1 galaxy tab wifi and a home made dock from a 7 inch tab and 10 inch tab dock. Using the oem power adapter that came with my tab. With my hdmi dock I watched a movie on amazon instant via the browser And I rented a movie from google. Both movies played perfectly through my 50 inch plasma tv via the hdmi dock.. I can tell you that movies would not play from google untell touchwiz update. but after the update I have had no problems whatsoever playing any content via hdmi. Also I don't know if it makes any difference but I have never rooted my tab. Good luck guys I don't know what's going on I hope you figure it out.
Hey mopar. Is your tv a 1080p? Both my hdtvs are 1080i so im wondering if thats causing the issue. I think i read somewhere that this tab outputs in 1080p. I dont think its the video player because it cuts in and out without running any programs. Its like every 30 seconds the tv screen will cut out go black and then come back on. its basically useless.
I believe my tv is the lower of the 2 not sure though.... it's definitely not a high end tv but it is new..w
my tv is a 1080p
I just got the adapter today and haven't had any problems with it so far
I just got the 7 " docking with HDMI out and it works like a charm, so it seems to be a production problem with the adapters. Brought me the 10.1 dock to put the piece on the 7 " base.
Hello all, and thanks in advanced for anyone who can help me out,
I have a launch day Galaxy S3 that will not properly connect to the official Samsung MHL Adapter. (PN: EPL-3FHUBE)
The problem is that the longer MHL plug will not fit all the way into the phone and kind of falls out. Its not going deep enough for the micro usb pins to catch inside the phone and take hold.
If i hold it tightly by hand it will display a picture on my TV, no problems at all. As soon as i let go, it disconnects.
I'm thinking this may be a defect on first gen GS3's as my brother also has a launch day GS3 and has the same issue.
Ive tested on 4 more GS3's (The entire family is on them) that were purchased 6 months after the initial release and the MHL plug fits all the way in. They all display a flawless picture and the connection feels very sturdy.
Looking at the two launch GS3's, inside the Micro USB port on the bottom of the phone it looks as if there is a plastic block above the pins keeping the adapter from going all the way in. The later models dont have it...
I'd really like to get this working. Ive planned to use the Pioneer App radio 2 with it and its been a long road. almost there but this seems like a make or break road block....
Does it sound like I need a phone replacement? Would this feature loss warrant a claim on my phones insurance?
When I have my cable connected (both original and aftermarket) to the phone, data transfer will suddenly stop when I move the cable around due to moving the phone. Say for example I connected the phone to the car to use Android Auto, if I get my phone and move it a couple inches to change the music outside of Android Auto, my connection will be lost and I'll have to reconnect to Android Auto again. At first I thought it was a bad charging cable so I tried a whole bunch of cables, including OEM Samsung and LG cables but no luck. Thinking it's a bad charging port, I changed the charging port but it's still doing the same thing. What could be causing this issue? Did I get a bad phone when I purchased it a year ago?

I totally understand what you're talking about, I've had the same issue since Dec '17.
No, it's not a faulty cable or even a faulty port. If you go to a service centre, they'll micro-clean the port which actually solves the problem albeit temporarily. It's just that the charging port on the 5T is way more sensitive to dust accumulation than most other phones. I had asked them if I could clean this out myself somehow and they said no, but I'm sure there must be some hack to DIY this.
I had the same issue, I used a plastic tooth pick to clean the charging port, some dust and cotton particles came out and since then charging works flawlessly
Well I changed the port and still having the problem despite using different cables. Guess I have a defective phone?
My phone does that when using a USB hub with HDMI, it does work with my friends S20+
What can it be?

Dex needs a Knox-App called "KnoxDesktopLauncher" in /system/priv-app/. Make sure its on your device. Maybe you have deleted it.
Not sure if related, but today I noticed similar issue on my regular S20 with USB-C earphones, they kept connecting and disconnected, which resulted in media pausing, and audio playing through loudspeakers. Wiggling USB plug gently, and phone recognized earphones, only to lose connection shortly against.
Gently Wiggling USB connector in all directions, including pushing it deeper, and pulling it towards yourself, reproduced the problem everytime, which leads me to believe the USB-C port is broken.
This is strange. My phone is just around 4 moths old, I very rarely use USB-C earphones, and last time I checked (around a month ago), everything worked fine. The only thing I plug on a daily is a charger, never in a car, or in any place where port might be stressed.
The reason why I noticed this issue only today, is because I wanted to listen to some music, and had AKG USB-C earphones laying close to me.
USB-C charging cable managed to break the port, in such a short time, just wow.
By the way, charging works fine, USB is acting up only when data transfer is involved.
So check with other USB-C devices, maybe your port is also broken. Plug bundled AKGs, play some music, and wiggle plug gently, music will pause if connection lost. Also you'll see headphone symbol flashing in and out.
I think people might not notice this issue, because pretty much everyone I know switched to wireless, so this can remain unnoticed for months, or longer.
And what's the case with root? I've rooted mine with magisk and since then Dex only connects/disconnects... Is there any option to get it working on a rooted device?
Same problem here, not Dex (i don't use it) but with charging.
It keeps connecting/disconnecting while charging if I move the cable. Really annoying.
It sometimes also charges slowly or not at all while it does say it is connected...

I think our phones have broken USB-C ports, and also, after reading many reports, starting to believe that S20 series phones have a weak port design. I'm very gentle with my tech, so at least in my case, it's either manufacturing problem, or a bad port design.
From what I gathered online, first symptoms of a failing port are problems with anything data related, like in my case, USB-C earphones connecting/disconnecting causing media to pause, then problem becomes more severe, when it's not just media pausing, but phone losing data connection entirely, resulting in complete connection loss to a peripheral, when you have to wiggle plug to reconnect, only to lose connection again shortly after, and finally, these data issues lead to charging issues, like ones you describing, connection loss to a charger, appearance of charging.
I still have around 20 months of warranty left, but sadly right now need my phone badly and have so much data that I need to back up, so warranty is not an option, at least for now, I have to buy wireless charger, in case USB-C port fails entirely. S20 keeps disappointing me.. Sigh.
