Unable to use external DAC with S8+ - Samsung Galaxy S8 Questions and Answers

I have no issue getting my Chord Mojo working with the UAPP app on my S8+ but when I try to use band camp, youtube or any other apps it will not route audio to the DAC properly. Note that UAPP uses a proprietary driver for routing data to the extetnal DAC. A notification comes up when connection Mojo to S8+ via micro usb-usb c otg cable(see screenshot below)
I have tried every option in the normal settinsg and developer mode but no matter what it just reverts back to "charge connected device". I have played around with all the USB settings in Developed mode;
Prevent automatic usb routing
Setting the usb device to audio source,
/MTP
Etc
Nothing works.
I even uninstalled UAPP, attached Mojo and opened band camp, still nothing. Worse yet, often it will freeze with Mojo connected and then restart itself or get stuck on the carrier boot screen during restart.
Seems that Android system is not allowing the device to connect properly although I can't be sure. I just want to be able to send all my audio to my exceptional Chord Mojo. Bummer because everything worked fine on S7 Edge running Android 7.0 when I selected MTP under developer options. Unless there's a fix I'll only be able to use Mojo with UAPP.

You should probably post over in the correct forum
Samsung Galaxy S8+
https://forum.xda-developers.com/galaxy-s8+
You have a Galaxy S8 Plus, not a Galaxy S8. That forum is dedicated to same device you have, and while the S8/S8+ are almost identical (in software), more people will be there to help you.

Done.

[Q]

Hi, This is actually incredible. Before upgrading to Lollipop on Galaxy S5 I was able to plug my DAC (a Dragonfly 1.2) via USB OTG cable into my Galaxy S5 and enjoy pristine usb audio without a single hint of a problem - all apps working - MX Player, Inbuilt Music App, Poweramp etc - all working perfectly.
Then I upgrade to Lollipop, which is supposed to be great for USB Audio, and it doesn't work any more. At all. I am now back to using an app called USB Audio Player Pro, which allows you to use DAC audio devices to connect to headphones and (thank god!) this still works awesomely, but I was really enjoying all my apps making use of my USB audio device and now that has just been screwed over by the update.
There was so much pleasure in just plugging in a usb audio device into the phone via an OTG cable and everything working great, but now I just fall on my knees and shake my fists in the air bellowing "WWWHHHHYYYYYYY??!!!!"
Has this affected anyone else ? I've restarted, factory reset since the update and googled the crap outta this and all I can find are people saying "Yay! USB Audio functionality has been added with Lollipop".
From my perspective, this appears to be balls.
I'll happily downgrade back to the older android OS if its possible just to get this one happy function back.

Samsung S7 mirrorlink support Appradio 4

Hope someone could help me with this. I have been using an iPhone for the last 5 years and in such I have a Pioneer Appradio 4. I am trying to see if I could make the android jump and purchase a S7 edge.
My Appradio supports mirrorlink as well as Appradio live which is garbage.
What I have been reading is there is no Mhl / hdmi support on an s7. However mirrorlink is available on the phone. Is anyone able to confirm that the S7 will connect via mirrorlink on my Appradio? I have been looking everywhere for an answer but most of the stuff is for the older galaxy phones. Sorry if I'm a bit ignorant to searching android stuff I've been chained to iOS and CarPlay for too long.
*Side question-- with Miracast do you lose all connectivity to cell data?
Thanks for all the help in advance
If your Pioneer Carplay head unit supports also Android Auto you can use this method for connecting.
Miracast doesn't interfere with the phone running data connections (wifi or mobile).
Unfortunately it doesn't support android auto. Which is pretty lame.
I dont't know about your head unit, but generally Mirrorlink should work also with the Samsung S7 Edge.
Thanks for the info now my only question is will it work with ARunchained reloaded once this is set I'll be ordering my Galaxy and getting off this iOS nonsense

For that app to work it's required to root the Galaxy S7Edge.
Anyway, if you're not used with Galaxy rooting, Knox and related possible Samsung warranty limitations, you can find these information on the forum. Moreover, to be able to root you need to buy the Exynos version, not the Qualcomm 820.

Okay good I found it on the website it has the exynos processor. Once it's rooted and I change everything I should be able to run this app then? I messaged Area51 hopefully he will message back regarding it. Thanks again for all the info and help.

Yes it works
I can confirm you that Galaxy S7 works with mirrorlink and the AppRadio 4. The sound and video quality are simply perfect. I have been using MHL before with Sony Xperia and ARU, mirrorlink is better. The only issues are the restrictions that mirrorlink implements in the navigation, no recent apps none slide notifications, etc. Hope some friend could mod "Samsung Mirriorlink.app" to break freee these limitations but also in the current situation i recomend you to use mirrorlink with Galaxuy S7 because as I said, the stability and quality are just perfect.
appradio 4 mirror link
did u have to disable android auto?

so it will only work with rooting your s7 edge? if so how do I root my s7 edge? I to want to use mirrorlink with the sph-da120
I Just installed the SPH-120 and I can only get my Galaxy s7 to connect to blue tooth. Tried the developer mode with USB debugging, Switched to MTP configurations, and both USB ports along with multiple APPS. and I cannot get it to connect.
When I connect to the second USB port, Both the phone and radio attempt to connect but the phone screen shuts off and the radio says incompatible USB (original cable).
Hi how do you connect wich cables you use to get it working like you say?

I just created an account here so I can add a reply in case anyone struggles to get MirrorLink to work. I got an SPH-DA120 to work with my Samsung S7 Edge. I went through the same process of connecting the phone, seeing the connected message on the phone screen, and then the SPH-DA120 screen says "Incompatible USB." I thought it was an error but it was simply my failure to understand MirrorLink. You have to first get a certified MirrorLink app on your phone and then choose the home button (or whatever it is...looks like a Windows 7 start menu) and your certified MirrorLink apps will show up there. When you choose the USB/Ipod2 source the HU will always say "Incompatible USB." In my case I used RockScout, which then gives you access to everything on the phone by selecting a "Choose Source" option--that mirrors your phone's screen and provides a gateway to everything on your phone.
Maybe this process is common knowledge about MirrorLink but I spent way too much time googling this and trying random things to get the phone to connect. Something else worth noting is you need a high quality USB cable. The HU seems fine with USB extensions (even cheap ones) but it requires a high quality cable to connect to the phone. Some work, some don't. Not even all Samsung cables work.
One more thing...I actually contacted Pioneer's customer support to get assistance with this. To my surprise they replied to my initial email within an hour. That's impressive for customer support at a large company like that. Admittedly I figured out that the USB cable was the problem shortly after I sent the email but the quick response from them was nice.
Can somebody confirm if a non rooted Galaxy S7 can MirrorLink using rockscout while in motion using the 7000nex soft touch bypass? Trying to mirror every app and function while in motion using the nex. This includes YouTube, Google maps, chrome etc
Great information here. I just started driving a Jeep with appradio 4 in it . I have a galaxy s8 plus. Any advice what to do?
Still stuck with my note 8. Stock android Mirrorlink works but very limited. I tried with rockscout, button savior, LG mirrordrive app etc to screen mirror my phone but n way. The only fault is with Messenger pop-up showing nicely on my car screen. So I tried rooting my phone with magisk and hide my root but the Mirrorlink app is not working anymore. When connected to my phone it says authentification not valid... and the database is no more the same when I want to add some apps in pkgnames...
Hi,
I have problem with mirrorlink pioneer sph-da110 with galaxy s7 edge when I connet via usb I see mirrorlink in appradio. I click in mirrorlink then I see Lg Mirrordrive an I choose this after that I have dark screen and nothing else happens. Somebody can help my where is problem?

Phone stuck in Charging Only mode

Hi all,
I got a Mavic Pro Quadcopter yesterday, but I cannot get it to talk to my LG V20.
When I connect to the remote via USB cable the phone automatically switches to "Charging Only" mode. I have tried changing it to MTP (media transfer protocol) in both the pull down menu and Developer Options, but it immediately changes itself back as soon as I open the Mavic Go application.
Can anyone suggest a way to force my phone to stay in MTP mode? I really want to fly my new drone. Arrrgggg!
PS: It works OK on my rooted Samsung S2 9.7 tablet, but it does not fit in the remote mounting hardware. Unfortunately I have the H990DS v20, so root is not an option for me.

your drone probably dosnt support the TYPE C connection, not the phone itself, im unsure how you could make this work tho, type c is a 3.0 connection, micro/mini usb 2.0. Probably a non-compatible connector for the drone sadly.
Just food for thought

PROBLEM SOLVED! A software update from DJI fixed the issue. The phone still shows as connecting as 'Charging Only' but it now connects to the drone correctly. Full video and control functions.
There is still a problem where the software crashes every few minutes, but it seems most users experience this bug. I'm hoping a further software update will finally make this device safe to fly.

Phone forcing MTP USB Config mode

Hello everyone,
I use my s8 to listen through music on my car stereo, which supports Android Open Accessory 2.0, allowing me to use USB to connect the phone to the stereo.
Since the latest update, when I plug in the phone it will not work with the stereo. I found out this was because the USB Config mode in Developer options would switch to MTP.
Switching to Audio Source mode would allow the phone to work, however every time I unplug the phone, it resets the mode to MTP.
Is there any way I can force the USB config mode to stay in Audio Source?
Thanks
Did you find a solution for this? Having the same annoying problems on several phones, most of them didn't even connect to my jvc at all, except note 4/s5 s4 oukitel u16(setting on midi) and now finally my s7 after root ing and 2 weeks of trial and error.. But have to connect 2 times before even getting in android audio mode and switch to audio source several times.. It's so annoying there has to be a good working funftional usb audio output.. Come on...

S7 Edge no longer connects to PC for media transfer

I recently upgraded from an S7 Edge to an S20 + Ultra, both using Verizon. Before upgrading, I used Win10/Windows Media Player to update music files on the S7 with no issues. Since upgrading I have successfully update music files on the S20 using the same PC, same version of WMP, and same WIN10 operating system.
When I got the S20, I kept the S7, planning to continue using it as a music source in one of my cars that has aux input capabilities but no bluetooth. That still works. However, I recently added a bunch of new music to my collection, and want to update the files on the S7. I have been unable to do so.
I have set developer options on the S7 and checked that Media Transfer Protocol is set, Despite this, the PC recognizes only that a device has been connected, but not that it is a smart phone, and hence the S7 is not recognized as a device by WMP nor does it show up in Windows Explorer.
Is it possible that file transfer to the S7 is blocked because it is no longer under contract to Verizon?
If so, does anyone know a work around?
Thanks
Dennis
Clear phone system cache.
Temporarily turn off Developer options and try.
Turn them on again and try.
Try in phone safe mode.
On the PC:
Check Event Viewer for error messages.
Try another cable and/or port.
In hardware management try rolling back the driver or search for driver.
Reboot, always reboot.
