When I plug in my s8+ into the Dex station my tv keeps saying signal received/lost/received/lost and repeats for infinite amount of time. I've tried different hdmi cords, different ports on the tv and nothing is working. Is this because of the Android 9 update? I haven't used my dex since before the upgrade.
Hope this is in the right place, thanks everyone.

Hello.
I have 47" Samsung tv (5 years old, 1080p), when I connect SGS3 with MHL adapter, with power adapter plugged in, the tv trying look for a signal and gives up with message "no signal". On the phone I see brief message saying HDMI connected.
When I plugin phone to a DVDR that is also connected to the same TV, phone also shows same message and also offer me a chose to use stereo or surround output with it. However TV still says no signal, but this time it plays sound.
Is there some hardware limitations in affect or I'm doing something wrong?
Thanks.
P.S.
The two different MHL adapters I bought as suggested at several topics on this forum, where people reported it's working for them.
The GS3 requires a newer MHL adapter than the old phones do maybe that's the problem http://www.galaxymhl.com

These are new 11pin adapters, people reported it's working for them...

i bought a new Amazon Fire TV from Staples, hooked it up, and nothing shows on the TV screen. There is no welcome or anything. I have re-installed the box several times. The HDMI cable is hooked into HDMI 2 and the tv is set to hdmi 2. I have unplugged the system several times. I have turned the tv on and off several times. The white light on the box is fading in and out. I cannot get anything to appear on the screen. I have replaced batteries in the new remote. Nothing is working. Since I bought it from Staples do I have to pre-register it somehow??? I have searched all the forums I can find and no one else seems to have this problem. Help?? Thanks.

Try a different hdmi cable. You don't have to register with anyone when you get the firetv. In my experience of building firetv's for friends (about 10 of them), one of them was indeed defective where the remote would loose its pairing in about 10 seconds. I'd say try another cable or ask for an exchange.
Helped a friend buy this. We were watching movies via wireless screen sharing (miracast) and it was OK but kept stuttering and dropping WiFi.
So I suggested getting an hdmi usb-c cable with power charging (4k). I was very surprised when it didn't work! Tried everything including downloading dex to the phone.
Connected the same cable to my s8 plus and it worked beautifully (dex) !
So why not the Samsung a50? Never experienced this on any phone before and have been connecting to TV this way for 10 years.
Need a different /special cable? Or no go on this device and can only do via wireless?
Thx
I haven't ever used HDMI mirroring on a phone but as far as my knowledge of Type-C goes, you need USB 3.1 to support all the alternate modes including HDMI and DisplayPort. The A50 comes with USB 2.0, so there is no possibility of getting Display-Out from the USB port.

thanks for that explanation, I'm guessing this the same reason we can't use type c 3.5mm jacks?
by that respect, pretty much any type c 3.1 can output through hdmi?
Thanks,
Scott
Type-C as a standard is a mess. I don't think you are required to support alternate modes in USB 3.1, so I suppose there are USB 3.1 Type-C devices that still don't output video.
Regarding audio, there is Audio Accessory Mode for Type-C and the concept of active and passive headphones/dongles, so not all dongles will work.
samsung A50 simply doesnt support dex. only s8 s9 s10 and Note 8 9 10.
getting usb c to hdmi wouldnt solve your problem.
there is how ever one possible solution, which is the universal android usb to hdmi cable. it uses ezcast app (same app for wireless). mirroring your phone but wont display netflix etc on your tv.
Samsung A20
So, I know that the A-series doesn't support DeX, but I was hopeful that it might still have the capability to project to a lapdock (like the HP Elite X3 or Nexdock 2) via USB-C and display even crudely (so, not the fully optimized DeX-ified desktop mode, but maybe just a mirror?), ideally allowing for keyboard/touchpad input as well. Basically I'm trying to come up with a solution for my mom whose company is phasing out the laptop she's accustomed to working on in favor of these lousy Samsung A20s, which she's gonna have a lot of trouble seeing and interfacing with on such a tiny screen and without a full keyboard (she's in her 60s). The lapdock thing is the only idea I've been able to come up with (though, it sucks that the A20s don't support DeX), but I'm open to any other suggestions if you think the lapdock route is a dead end. Thanks!

The A50 doesn't support MHL(display out protocol) at all for some reason, which is quite disappointing. At least wireless display casting works well.
Has anyone gotten DEX to work? I cannot seems to get it to work at all.
Unable to run
dex here as well
yep works with my lapdock +tv/monitor
hi,

Samsung's DeX page says it only works with the Note 10, is that the version you're getting success with or do you have an older version that worked with other Galaxy phones? If the latter, is it available somewhere?
I can get it to work using a generic USB C to HDMI adapter, and a USB C with PD hub plugging them in to my TV and also monitor.
I got DeX to work with DeX Pad, but I had to have the phone open. It wouldn't fit in the connector properly (I think) because the case was too big. It wasn't a good experience with the phone open half hanging off the pad.
I can't get DeX for Mac to work. The app auto-launches on my Mac when I connect the USB, but I get a message saying to reconnect the USB or reinstall the driver.
DEX works fine on mine. If it could help you, i found a solution for the HDMI (connected / disconnected) problem.
Step by step here, very simple...try!

I have a USB OTG cable that I can use to connect USB devices like flash drives, keyboard etc. and that works fine, but for some reason my phone won't charge whilst the OTG cable is plugged in.
Am I missing some really obvious way of getting this to work? Is it software based? I'm rooted and running Lineage OS if that makes any difference. I've tried several different OTG cables, I've tried connecting to different power supplies, different USB cables, different outlets, I've tried going into developer debug settings - nothing seems to get it to charge and data at the same time.
I am also interested in the topic. Trying to run Octoprint for Android and charge at the same time. I bought an OTG Y cable and the problem is that the phone is either charging or communicating with the 3d printer. Never both at the same time. I've researched quite a bit on google and it turns out at least on some devices the required effect can be achieved but I haven't been able to find anything about huawei devices. It is most probably a software limitation.
The same problem but i have Samsung J5 2017, i have rooted device so there is option to modify system files
Gosh! Would love to get this working. Any news?
