I have the Galaxy S8+ Snapdragon and I love (almost) everything about it.
I am on a mission to have a portable desktop experience, but I am running into an annoying issue. I cannot find any solution to maintain a positive charging state whilst mirroring to an external display. Fast Cable Charging and Fast Wireless Charging both drop to regular charging speed when I am connected via USB-C to any external device. Regardless if I use the Samsung wireless fast charging dock or a USB-C dongle with passthrough charging, I cannot maintain a positive charging state and my battery gradually, or sometimes hastily starts to decline.
I have tried
EP-NG930TBUGUS Wireless Charging Stand
in combination with:
direct USB-C male-male connection to ASUS MB169C+
direct connection to any monitor with Samsung Superior "4K Ultra HD" HDMI Adapter USB-C to HDMI Adapter
I have also tried a USB-C hub: Cynergy mini USB C Docking Station USB 3.1 4K HDMI and Ethernet Multiport Adapter with USB C Power Delivery for Charging and USB 3.0 Hub
Every setup works! Mirroring is displayed at 4k 60hz, 4k 30hz, or 1080p 60hz, depending on which device is used. The only problem is, no matter what settings I change or other battery draining services I disable, the battery keeps decreasing, despite being in a charging (not fast charging) state.
Has anyone else tried this or been able to achieve what I have not? If I cannot do it, HOW CAN DEX DO IT? My thought is that it must be in the software to enable it if Dex is recognized, because they know they have the phone on a cooling stand and they don't want a bigass battery explosion mishap like they did with the Note 7. So, they intentionally disable fast charging while connected to external devices.
Fast charging is disabled once the screen is on, how do you know dex still allows fast charging while running??

Good question.
I gather that your point is fast charging is disabled with an external display is connected, because external displays are always on.
Unfortunately I do not have a Dex in my possession so I cannot speak to how it functions. That being said, regardless of whether my phone is in fast charge mode or not, my battery depletes when I am plugged into any external display. This includes external displays that have their own power source... like my TV for example.
So that would beg the question: how can Dex retain a charge on the connected external display when all other devices I have tested cannot? The only answer I can come up with is that the device allows an accelerated level of charging when connected to a predetermined external device. It makes sense, considering the Dex desktop experience can't seem to be invoked without being plugged into the specific Dex hardware...
Thanks for your response, I am looking for any and all constructive troubleshooting here.
Isn't the screen on when it's connected to the external display? That would disable fast charging.
Hi, did you find any solution? I'm on this mission too, in fact, i'm coming from a moto z because it lacks of hdmi output, and i think you already know that chromecast isn't a solution.

How can I disable USB charging on a rooted S4, or rather default to wireless when both are connected. Yes, I have read the posts about cutting the 5v wire, but want a less permanent solution that still lets the usb port function normally.
I have the Pioneer AppRadio 3 and use my phone for maps/GPS and pandora in the car. When the MHL HDMI cable is connected, it only charges at ~500mA (due to need to transfer data) which is not enough to compensate for the display, bluetooth and cpu usage, therefore my phone discharges when connected while driving.
I installed a wireless charging pad and receiver rated at 1000mA, hooked it all up to a hardwired 5V 2A power supply, and when it is in place, the phone charges as expected until I plug in the MHL HDMI cable. It then disables wireless charging and uses the ~500mA from the cable instead.
The MHL HDMI and bluetooth connection are required for the radio system to function.
Since it chooses USB over wireless when they are both connected, there should be a setting buried deep somewhere to affect which it chooses.
Any help is appreciated.
Cheers,
Brad
Hi All,
I have an issue with my Galaxy S4 (CM12.1) and the Leicke Clever Dock multimedia and otg dock I'm using. If I operate the dock by the instructions (plug in usb peripherals then plug in HDMI then plug in micro usb power before plugging the phone in) it works flawlessly. If I then power off the dock leaving the phone on (i use macrodroid to set it into a low power mode) and then power up again it starts charging but wont transfer the screen to hdmi unless I pull out the phone and plug it back in.
I assume that the issue is the trigger for MHL but I cant understand whether it is something in the phone that isnt putting the usb port into mhl mode or if its the dock not doing something.
A few options:
1 - Find a new dock that enables this (im struggling to work out whether any of them can, even the official samsung one)
2 - Get the phone to enable MHL when charging (i have searched high and low and cant find anything that might be able to help
3 - Get the phone to disable and then enable the usb port (dont know if this will even solve the problem)
4 - Other (suggestions appreciated)
Im also investigating screen casting and will see if there is a route there but I will also need the OTG capability.
Cheers

I've tried a couple of devices that claim to connect V20 to tv by wired usb c to HDMI connector. They work for a while then the picture is lost or the phone itself freezes up. About the longest play I've gotten successfully is an hour but usually something goes wrong within 15 minutes.*
The phone has been out over 6 months now so I thought someone may have found a really dependable HDMI connector? I don't mind the lack of power in because I can always change batteries but phone should be able to play through HDMI long enough to watch one movie. That's all I really need hut I don't want to have to screw around with it 10 times to watch one movie.
Thanks so much for your help!
I've been wanting to make use of this feature, but haven't extensively yet. I have though gotten to make fair use of a micro-USB to HDMI adapter. A few trouble spots come to mind here.
Sounds like you're powering the adapter/phone from an external power source? How good is that power source? My micro-USB to HDMI was distinctly less reliable when plugged in since I was merely powering it from a normal USB port. Try running it entirely from the phone's battery. If this works better then it could be you really need a higher power source when using the adapter.
How good is your HDMI cable? Depending on how strongly the phone/adapter drives the HDMI signal, a lower quality cable could break the camel's back.
I've been running into a different bit of trouble with USB-C to HDMI adapters. I've found several of these, but whenever they've got a USB-C pass-through, the pass-through is strictly for power and does not carry the USB signals. The MyDP specification allows for USB3 to be passed through if 1 or 2 pairs are used for the HDMI signal, but allows for USB2 to be passed through no matter how many pairs are used for the HDMI signal. There are adapters which also include USB-A port(s), yet none which include an external USB-C with the USB signals. Grr!
I use C to HDMI not micro usb. V20 doesn't use micro usb. It uses slimport. I have one adapter which allows simultaneous charging and one strictly slimport C to HDMI. Both behave the same way. I have a high quality 2.5 foot HDMI wire.
Power source was Samsung tv usb powered output 1 amp. Point is I have the same issue with pure slimport and no charging.
The one that allows simultaneous charging does in fact charge and work but always craps out but so does the slimport C to HDMI.
Hmm, entertaining what you find when you do research. I suspect the V20 is using the "MyDP" specification, which is the official specification name behind "Slimport". Seems there are at least two other video out methods for USB-C.
I haven't done enough with the video-out feature of my V20 to have much experience yet. With a V10 whenever an adapter was plugged in without external power there were no problems, but when an adapter with external power was plugged in video wasn't reliable.
I'm interested in reading if you find out anything.

Sorry I haven't tried, but its seems to connect smoother the a wifi dongle.
does anyone know if there's a compatible dongle for the V20 with not only hdmi but also power input and usb host?
Happening to me too - Any suggestions
Your situation's description fits my problem exactly. I have a USB C to HDMI that was vouched as working by several V20 owners. I plug it into my Dell monitor to play games on a bigger screen. It works well for a while, then disconnects and popup on my screen says something like, "LG Bridge has stopped working do you want to exit?". Once this happens, it's almost impossible to get the V20 to share the screen again. It's not a hub, just a USB C (male) to HDMI (female).
I'm interested to use Sidesync to have my S8+ screen on my PC. Wirelessly, it's unstable as I use VPN a lot. The best is via USB but I worry if my phone is continuously connected to a USB port, battery may damage as it will do like a cycle of charge/discharge. Any idea, guys?
It should not be a problem, unless your phone is using more power than what it is getting out of the USB. Once your phone is fully charged, it keeps using the energy directly from the incoming electricity.
But if the discharge is greater, then I would definitely advice you against it.
The phones are pretty intelligent to say the least.
To add to that, your best bet is to use a true USB 3.0 or 3.1 Gen2 port to connect the phone - the latter if available. These ports provide extra amps to make sure the phone is getting as much power as it can use. Do NOT use a USB 2.0 port, as modern phones consider the 500mA max that USB 2 can provide to be the bare minimum needed to charge.
Thank you both
Hello guys,
Does anyone knows if there is a otg cable/hub that can power the tablet and be able to use data like usb connected at the same time?
Thanks
The 2019 tablet does not need this, since the port is USB type C albeit USB 2.0; I have connected mine to a hub and have pass-through charging and data. OTG is not really a thing any more since USB type C came about.

Can you share the type of hub you have been used?
Is the charging speed fine?
Kingston Nucleum. This tablet is in my car and the hub receives power from a 12-14v converter providing USB C PD and USB 3.0 fast charge. Ultimately, the hub defaults charging voltage to that of the lowest device connected. In my case a Sandisk SSD and a Meizu HiFi DAC Pro. This generally means that charging is slow, however it depends on your configuration. I'd say that the charging speed is fine, however it only charges when the car is running or in accessory mode and the tablet is always on in that state. As such the excess power it uses to charge whilst running is only a little more than it uses. It might charge faster if I power the hub from the USB C PD port, however I don't know if this is just pure amps or whether it negotiates higher charging voltages. I don't know if the Nucleum hub allows negotiation of higher charging voltages.

Nice, i'm using for the same purpose.
In my dash car
I'm also using MacroDroid for automation.
My issue right now is how should i leave the tablet when i turn ignition off.
I Think i will just shut it down, but i don't like to wait 30 seconds to but again when i turn it on.
What do you do in your case?
I'll have to check out MacroDroid. I'm currently set up with AutoMate, however there's a few annoyances which I think need ironing out. Vanilla Android Auto might not be the most exciting, but it's certainly the most friendly for driving safety.
I leave my tablet as-is. AutoMate automatically wakes the tablet into car mode on USB power and goes to sleep when it loses that. My car (Chrysler 300C) has accessory power for 30s (I think I can increase this in the EVIC) after the ignition is turned off which keeps the charger energised, and by extension the tablet. I'm not too bothered about having to boot up the tablet if it does discharge its battery to shutdown. I think it's maybe a week or so for it to do that, likely less when the tablet ages. As long as it charges and runs on the supply happily I think we're good. In that instance, I might have to see whether an auxiliary power bank would be a workable option. Not at this stage though. Bear in mind that most modern car head units still take about the same amount of time to boot as an Android tablet anyway.
I'm having minor USB issues myself, however this is down to the cable I need not being available. A lot of USB C "charging" cables are only pinned for power and not data. This might be part of any USB C issues you might be having. I myself need a USB C male with a tight 90° or 180° turn, out to a USB C female for the hub's pigtail. I might have to make the choice to fabricobble myself a USB cable just for this purpose....
This is a photo of the install, prior to me wrapping it in 3M brushed black steel vinyl.
I'm updating all of my comments in various threads on this. My setup with the Kingston Nucleum hubis having minor issues. The tablet still needs to be powered up before I turn on the car or at least supply power to the hub. It seems that if this is done the other way around, that is, to power on the car accessories (and hence the hub) then it seems to end up staying as the "device in charge" of the USB network. The tablet charges (slowly) but doesn't mount the USB SSD drive or the USB DAC. If the tablet is powering the hub (in charge, so to speak) then applying power to the hub via the car accessory supply has it working as expected. This does mean that the tablet ends up with a power drain when the car/USB power supply is powered down which isn't ideal. I've gotten into the habit of turning the tablet off when I park for long periods of time, however I need to boot it up to "take charge" of the USB hub network before I can start the car. It's a bit of a bummer.
I'm unsure whether this is a tablet hardware/software issue, the hub or whatever. Going into Android settings and trying to alter the default USB behaviour returns the message that it "cannot switch roles" or something along those lines. I'm beginning to think that this might be the USB hub refusing to switch/relinquish power supply roles once it has external power and hence not allowing the tablet to mount drives or see connected USB devices. It's weird behaviour, because you'd imagine that if the hub were connected to a laptop this would be a common action.
If it helps, I've read that OTG function is not included by Samsung for their device's USB ports. I've been trying to connect some together to perform file transfers with no success. However, I have been able to transfer and charge simultaneously between my SM-T510 tablet and PCs with the USB configuration set to file transfer.
