Help with android auto on the Duo.. - Microsoft Surface Duo Questions & Answers

I use android auto through a carlinkit dongle. When using my note note there are no issues I just plug in the note and android auto starts.. When I try with the duo its not recognized, even though AA is installed and running the same version as the note. Any ideas guys ? this is driving me crazy.

also some peripherals don't work, I have 2 usb video glasses one works, the other as soon as I connect it crashes.. could this be a power delivery issue? if so is there a way to know?

I don't use AA but have it in my Ford explorer. It does pop up for me when I charge the duo with my OnePlus cord in the car. Did you try a diff cord

[Q] MHL being wierd and OTG crashing phone

ive had my MHL cable for over 2 weeks now and its got the official samsung logo - and i got it from suntekstore... only problem is i havent got it working...
ive tried with my dads stock 2.3 i9100 on a viewsonic monitor and samsung tv
same with my 4.0.4 i9100 resurrection remix 1.7 + siyah 3.1.2
the other two items i got from suntekstore were 2 OTG adaptors which fail to work... (i also have one that does work from another store) so i think it might be the MHL adaptor itself
yesterday i was frustrated and kept plugging my phone in and out of the samsung tv.... and BAM i got a visual =S after like 10 'no signal' and 2 resolution not supported... but the screen was stuck in portrait... thats the closest ive come to using MHL properly!
on top of that... when i use OTG keyboard connection... the phone freezes if i try pressing caps lock to check for power on my phone! any one else running same OS version and its working?
When successfully connected via MHL the S2 will display in portrait, so that was normal. Apps that run in landscape will do so when run, or where sensor orientation works, like in photo gallery etc, you can rotate it to landscape yourself.
No, as for your issues regarding getting the picture to stay on; first, you did have the Samsung Charger plugged into the MHL cable right, and the correct output channel selected on your tv?
Assuming you did for both the above, the problem is likely with your hdmi cable, not the tv's. Have you tried using different cables? I have a problem with one of my hdmi cables where the screen goes black for a few seconds whenever it pleases, with another cable (which comes with the sky box), it stays on all the time. So try changing cables and see what kind of response you get.
Also, some users have mentioned that they seem to get picture when they put their phones into flight mode first, I've never needed to do this, but give it a go and see what happens. Once you've got your picture up, you can use your tv's remote the control your S2, assumming your tv supports that function.
Hope that helps
I have not tried that rom but last I heard any source based rom doesn't have a working MHL output. I don't know the status at all of OTG on source based roms.
You said you tried it on your dads stock phone but didn't clearly state if it worked or not which it should if the phone is stock. So use that as a basis of if the adaptor is broken.
thanks guys - yeah it could be the hdmi cable... they are pretty cheapo - but on seeing 2 OTG adapters from the same store dont work... the MHL being broken cant really be a coincidence? it was in delivery for over 1 month =[ maybe someone broked it! lol
I think in the end it was the MHL adaptor... ive got a replacement sent out as now the phone wont even recognise power to charge when plugged into the mhl however the charger directly into the phone works! argh may be a long wait for the replacement took 30 days to get my other shipment! may have to resort to a more expensive one

Its cool. I'm testing same setup have u had any problems with auto connect bluetooth?
Not problem. . But I need push a sony radio for connection bluetooth App remote. .
I have call a Sony for this .. but need manual input..
Any one interested in this check out proclips (Google them). A non invasive easy way to install a tablet in the car. Works great with the Ford Sync system but anything with Bluetooth would be good. I've had iPad's, Note tabs, and now the 8.4 in my Fusion.
8.4 in my Jeep
Here's my setup in my Jeep. I got a custom mount that sits over the stock stereo. It slides in an out and locks. When I want it more secure, I slide it out and I have a lock box below my seat.
I ordered a ground loop adaptor to fix the hum when it's being charged and plugged into AUX. I'm currently shopping for a DAC that I can connect to a charge enabled OTG cable. The best I've seen is LAVA SimulCharge USB 1 but I wish it had more ports. Anyone find anything better?

I have the lava adapter works pretty good. U can buy a 1 male to 3 female USB adapter for more ports. Make sure u have a good 2.1 amp charger and cable for the lava or it won't charge to good. I use a official Samsung car charger and the USB cable that came with the tab pro gets about 1000ma with my DAC hooked up. I use the Behringer uac 202 USB dac best for the money. Has optical also.. No ground loops or noise with optical.

Thanks. I was hoping I could get a 1/3 USB adaptor for more ports, but I didnt know if it would work. I have a two different 2.1 amp chargers now, and it barely gives any juice to it. It says max 1200 or so but it bare;y gets 3-400. It keeps the screen on and it drops a % every 5-10 min. I looked at the Behringer uac 202 but I'm connecting to a stock deck that goes have RGA inputs so I'm going in through an AUX jack. I could try an optical to headphone cable I suppose.
The ground loop cable I got killed the hissing noise. Is the UAC 202 a noticeable difference worth the extra cost and time setting it up? I'm concerned it will slow down charging even more. Does it suck up a lot of juice?
The sound difference is huge with the 202 dac even if u use the headphone out jack. Alot more clarity and output. doesn't suck much juice at all. U should invest in a Samsung Branded car charger most chargers say 2.1 amps but put out half.
Thanks, I just purchased the 202 and the lava so I'll be able to test this out this weekend.
I couldnt find the general samsung car charger that didn't have a cord already attached though.
Now I just need to find a USB backup camera solution and my car setup will finally be complete.

Goodluck. The 3 port one looks pretty large. Does that function differently than if we were to buy a 1 to 3 USB adaptor?
I have my 1 port working correctly. Strangely whenever I use the Lava adaptor it lists it as 100% charges right away, but if I unplug the charger it drops back down to whatever it really is. Not a huge deal, but annoying to not see the accurate battery level when plugged in.
The 3 port adapter is supposed to be better with charging and has a button for charge only wich is cool. And according to lava there is no power feedback from the tablet to the the adapter. The tablet port keeps my usb dac on even when I unplug power With the one port. And I'm sure that the 3 port will have no problem with a dac hard drive and mouse (hopefully will let everyone know when I get it in a week or so).the one port would have a power supply issue with all 3 devices.

Otg not working in Mate 10 Pro

Hi.
I just bought my mate 10 pro and love it.
But I just notice that the otg doesnt wotk, or I dont know if hauwei needs a apecial adaptor or what.
I come from a LG V20 and I normally use a 4 in 1 card reader to conect it directly and it was great, now I try it in my mate and it doesnt detect, I bought a ner 4 in 1 card reader and is the same, do I need to enable something or any one has an idea of what could be the problem.
Thanks
mate 10 alp L29 8.0.0.129 (C185)
i hav two type c dongle nd an adaptor,it reads/detect the sd card but goes blank just as quick.when i plug in two notification pops up one sd/usb ready to use nd the other is 5 options like reverse charging,transfer.....
dunno where the prob is
Mine works fine (BLA-L29)
im having the same problem. just got this phone, and trying to use a protable hdd which worked with my Galaxy Note 8, Oneplus 6 and laptop. It just comes up with reverse charging. When i select MTP it just reverts back to reverse charging straight away. Please, any help or info would be appreciated. TIA
Looks like your adaptor is not supported. The Mate 10 Pro support anything (mouse, storage, keyboard.. ), got USB 3.1 and display port 1.2
ALP-L29 8.0.0.141 (c636)
Moving this thread up.
For the past two days now, I have encountered the same problem. When I plug in my HD via the OTG adaptor, I only get a notification for how the USB can be used, but I am unable to toggle between reverse charging and file transfer. It only goes to reverse charging. Any time you select file transfer, it goes back to reverse charging.
This also happened yesterday, and after unplugging and plugging the device again, I was able to mount the HD. Today, I don't have the same luck.
I'm using a uGreen OTG adaptor and a 1TB WD hard drive which I used flawlessly even with my old phones (Huawei P8 and P10Plus). I've used the same combo with my current Mate10 before, but I have encountered this problem after the latest update (for GPU Turbo).
Help?!
I try 2 different OTG and neither work. One for Radio shack and another Xtech. my Cellphone model BLA-L29. Any clue?

USB OTG HUB and ANDROID AUTO

Hello Everyone. I have a Mazda 3 with Android Auto that does not natively support FLAC files. So I figured out a Solution where using Android Auto I am able to use MD Player to play the flac files on my phone. Now before anyone says that I am streaming over Bluetooth so it doesn't really matter. I am also able to go into my Mazda Bluetooth settings and Set Bluetooth to only be the source for Phone calls. This forces Android auto to send the Sound over USB. And there is a huge difference in Sound. For example over Bluetooth I have to crank up the sound to 3/4 to hear what I want while over USB Audio i get the same volume at 1/2. There is also a clear difference between Flac and MP3. Especially at higher volumes.
When I discovered I could do this I thought to myself let me order a USB C Hub, connect my Phone to the HUB, Get a USB male to USB male cable for Android Auto and a 256gb Thumb Drive to fill up with Flac Files. This is where my problems start. Connecting the 256gb Thumb Drive to Hub works perfectly, except that I have to use FAT 32 which is fine, since I wont be using this for movies. When I connect the Android Auto cable to the Hub though it does nothing I tried a USB 2.0 and a USB 3.0 cables to see if that would make a difference. I also tried using a USB OTG adapter without the HUB to see if that launches Android Auto and it does not work either. I tried using my old phone a Nexus 6p and it also did not work. So now I'm thinking Android Auto does not like USB OTG. Could this be Kernel Related? Or am I wrong to assume that something like this would even work on a Phone.
Additionally I bought a USB C powered hub so I can charge the phone while in the car. But when I connect power to the device it charges the phone just fine but it will no longer see the Thumb Drive. If I disconnect power it will not recognize the thumb drive until I restart. So far I have tried 3 hubs. The first one was the cheapest one I could find so I thought that could be the problem. I then tried another Hub I had lying around with the OTG Cable. This did nothing, finally I ordered a nice Anker Hub that works just fine with my wifes Macbook Air, but not with the phone. Any help or Guidance would be appreciated. I am open to installing a custom Kernel if this will solve the problem. Thank you.
Did you ever find a solution? Looking doing the same thing with my pixel 3 xl and either a thumb drive or ssd. I think it has to do with the way the otg cables are wired. The data pair might be the same for the drive as android auto. The otg cables dont have all pairs wired as a true y cable.
Thanks

Note 20 5G N-981U1 Android Auto wont connect via USB.

Hi everyone, I've been searching on XDA and Google about connecting my stock note 20 to my car. USB connection doesn't work.
Yes, my cord is fine and works with other devices.
Yes, the USB port on the phone is fine and connects to my computer and TV.
This is not the only samsung device I've had an issue with.
The car is a 2019 Impreza that has android auto standard.
I've reset my phone and my headunit. Still doesn't work.
Anyone else have this issue and got it figured out?
