P30Pro and Android Auto

Hello,
i have a P30 Pro with the Firmware VOG-L29 9.1.0.178(C431E4R2P2) and a problem with Android Auto.
If i connect the P30Pro with my car, there is a connection error.
The USB Settings on the phone switch automaticly to only charging. If i switch to data transfer it changes automaticly to only charging.
On the last Firmware i have no problems with the connections to Android Auto.
Have anybody the same probleme or an idea?
Thank you
Lapidu

Sometimes, I have to select the data transfer setting two or three times before it will connect to the car. But it always works after 2 or 3 times. USB debugging might also make it work better.

I have no problems and never had. Also i never changed the connection mode, nor did i enable usb debugging. I'm using the original cable, though. Some cars/phones seem to have problems with cheap usb cables, my dad also noticed that but is fine after using the original one.
Was it working once? Did you registered the car in Android Auto or has is failed ever since? Is there a message on the phone?

Witch firmware do you have? And what for a model?

Worked on every firmware since beginning (185 atm). 128 GB Version

I have similar issue, the connection "dies" everytime I connect it to the car for the first time after being parked. Takes about 1-2 minutes, then it disconnects. I haven't investigated what the phone does, but my quickfix is usually to plug the cable in/out. After that, the connection is stable. The issue started around .162 or .165

Hi all. I have this problem as well. Just bought a carplay, but my P30 Pro (Android 10) wouldn't connect at all. I tried with different cables, including original one, still no luck. WIth any other cable it works fine from a Samsung Note 10+. Any idea?

I have the same issue with my P30 pro and civicX
After emui 10 I just can't use android auto in the car.
I have the app on my phone, and it works on the phone. But when I connect to the car it wont work.
(all the Samsungs and apple that I have home work perfectly)

I'm using emui 10 and android auto.
I have the same problem as all people here.
After usb plug, only charge (that's not important) . Some times connects at first time and some other i have to select other usb connection mode (i discovered unplug cable is not necessary)
Will try to change usb cable with the original one

Hello there! I'm trying to connect my P30 Pro with Android Auto on a Seat Leon. I always receive an error message and the connection with android auto always fails. I tried to enable Usb Debug, to install old versions of AA on my phone (for example v. 5.3 and v. 5.4). I'm using the originale data cable (actually two of them since I have two P30 pro at home). AA worked well with my old Samsung Note 8 and Mate 10 Pro. Do you have any suggestion? Thank you!

you guys need better cables, use the factory Huawei one and you'll have no issues.

I'm using two original cables (I have two P30 Pro at home). It isn't a cable problem but probably an issue with Android 10 and Android Auto. This problem affects different recent models of Huawei (P30 pro, mate 20 pro..).

Hello there! Just an update, AA doesn't work only with the Seat Leon. I tried other cars and everything is ok. I will try to update Full Link Seat.. It should solve the issue. Byee

I had android 10 and 10.1 stock cable a no issues whatsoever. I just traded phones with my little bro for a s10e ??

Hello! My p30 pro can connect with Hyundai kona (2021) via usb cable. But in wireless mode, the coonection has issue: the wificonnection is over the 4g+ connection, so, I don't have mobile data on the kona's device. What can I do?

Android auto and Samsung

hi, my Samsung s20 ultra was working until a few days ago but through mirror link, im trying to connect through android auto but I keep getting a message on my car computer screen saying to connect a compatible USB device, I know AA is built into my fone, It mostly for navigation I need it thanks

Your car needs to be able to handle Android Auto. You say you used Mirrorlink. This is a different system. Check if your car is compatible with Android Auto. My guess is, it is not.

Huawei P30 Pro no longer USB Synching

I had my phone, a "Huawei P30 Pro" for about 9 months then at the beginning of the first lockdown (March 2020) I was called to Italy.
After a few days there I started to notice that I was having problems connecting my phone with my PC's & Mac's using Hisuite?
I tried revoking HDB Debugging mode, then re-enabling it, I went through all the recommendations that I found online but nothing worked.
I also uninstalled and reinstalled Hisuite, I reset all settings, I then wiped my phone completely and tried to reinstall it as a new phone hoping that would work,,,,it didn't.
Around about that time I bought a drone to do some ariel photography, I could never get the P30 Pro to recognize the drone it just kept saying that couldn't find/connect to the device, so I tried my partners P20 Pro which connected via the same USB cables I had been trying previously and they worked fine it also worked flawlessly with the drone?
I even went out of my way and bought a 'Huawei P smart Z' to test with and sure enough, it connected and worked perfectly with the drone and USB connection?
Now, even though I had called Huawei support on a few occasions within the warranty period they are now saying that it's out of time and there is nothing they can do.
I called them when I was in Italy during the lockdown where I was there for 9 months looking after my parents.
My thoughts are that it must be the synch port and perhaps tied into something on the logic board as it is not just USB synching but also when connecting 'Bluetooth?' to the drone which is strange as it connects to other Bluetooth devices, my watch, printer, TV, BPM, etc..
I love this phone especially the camera/video side to it but now I can no longer get my work off unless I send it to myself which is really cumbersome when you have 2-3 hours worth of 4K video recordings, which I do often.
The other thing is I really want to use this with my drone but how the heck can I get it to see the device and again I have tried just about everything and used other phones from other manufactures as well as Huawei and all connect/work fine with the drone and USB syncing.
I myself am a bit of a technical sleuth but this one has me hammered.
Is there anyone out there who can perhaps shed some light?
(I am looking for 3 questions answering here.)
1.what is the probable fault?
2.what is the repair solution?
3. how much could it cost?
Thank you
I will also try posting this request out on a few other boards and see what comes back.

i have the same problem

Android Auto in Norway

I have big time trouble connecting my A12 Android Auto to my brand new BMW iX3. My Oneplus Nord connects flawlessly, the A12 does not. On Samsungs website I read that Norway is not among the countries allowing Android Auto (https://www.samsung.com/ie/support/...fficulty-connecting-to-or-using-android-auto/), could that the reason?

I cannot believe that.
I live in the Netherlands and we are also not in the list and we can use AA without any problem, but, your phone AND carsystem will have to connect with each other.
It sounds more that your A12 does not have the right software for it.
Go to apkmirror site and download the AA software and install on your phone.

I have downloaded the latest version from Google Play, isn't that version as good as the apkmirror-versions? My A12 connects OK with the car when it comes to hand free phone operations over Bluetooth, but when trying to establish AA, the car says "The connection failed. Check both the Bluetooth and WLAN settings on the mobile unit". Both BT and WLAN are active on the phone, and during the process an AA logo splashes on the mobile screen.
Edit: I have downloaded and installed Android Auto 6.8.613323 which I suppose is the lastest release. Same result

Ah, now i get it.
I had a Nokia 7plus and my radio-unit worked, This summer i switched to a new Nokia X20 phone, and had the same error.
After switching the car-cable with the cable that came with the new Nokia, it suddenly worked.
So try to use the cable that came with the new phone, instead of the old cable from the previous phone.

Thanx for the tip, elot01! I switched the cable to the one that came along the A12, but nothing happens when connected to the car USB except from battery charging and the option to transfer files. I am in contact with Samsung support, and so far they have been helpful. But they have not been able to solve my problem yet.
Once they have, I will post the solution here. But any tip for the forum community is highly welcome.

Samsung has given up and redirected med to Google since "this is a 3rd party SW". I haven't managed to find any Google support center to contact, but I have figured out the problem myself.
I want to have a wireless AA, and it seems like this is only supprted with handsets capable of dual band wifi, ie. 2.4 and 5GHz. The Samsung Galaxy A12 only support single band (2.4GHz).
So there goes my A12 back in its box to be placed in some drawer and forgotten. A low-priced telephone, but still a waste of money
A tip to Google/Samsung: Why not display a message saying "Android Auto is only supported on dual band wifi mobiles" when only 2.4GHz is supported?

If you want wireless, also take a look at Carsifi (still in Kickstarter) or AAWireless (former kickstarter).
Then you don't need a new phone

If you want a dongle slamming aroud in you car occupying one USB-port this solution is probably OK. But it's much easier to spend the 85$ extra on a mobile with dual-band wifi.

P30 PRO not working Android Auto - Wired

Hello,
I have a Huawei P30 Pro sw EMUI 12.0.0.134(C461E1R1P2) VLOG-L29 and I cannot connect to Android Auto (Mercedes Benz). the problem must be an incompatibility of P30 PRO since the AA works fine with other Phones.
I've reset Mem&cache of AA App, updated the AA SW version and the other Apps. Also testing developer AA menu optons.
I have come to connect sometimes with difficulty to AA car but I am not able to find a pattern so that it works well continuously. When I try to connect again it doesn't work.
My AA version is 8.3.624134.
I am surprised that there is no posts about it since I imagine that Huawei phones will have many compatibility problems with AA.
Anybody can help me?
BR

Works fine with Dacia AA(wired). Don't have a MB to test...same version AA
Did it work with EMUI 11?

Now I can connect. I've done three actions:
1. Buy a new official cable.
2. Update all the Apps. It's important that Google assistant works well.
3. In developers menu, tick on developer mode.
Now AA works fine but sometimes it disconnects. Maybe I have to revise battery savings App conf., or the screen must be ON all the time. I don't know ..

I've used P30 pro for both wired and wireless AA without any problem for more than year. So .
- You dont need official Huawei USB cable, any decent cable will do. I believe that was your problem, bad cable
- Updating all apps is in general good thing to do, but it doesn't influence connection with AA at all
- Forget developers mode, please . No need to think about it, and you actually may harm your phone by playing with it. It doesn't have any influence on AA
Enjoy AA in your vehicle

I completely agree with your appreciations. I’ve forgotten using developers mode and it seems to work. I bought a high quality cable and I cleaned the USB-C connector.
Currently I only have a problem: disconnections every few minutes (variable from 2-10 minutes). I am testing some things: AA permissions, non Battery savings, always on of the screen … but I can't find a pattern. Any idea what can be the problem? Does it happened the same to you with your P30 PRO wired to AA?

I've switched to S22U last two months, so i cant share fresh experiences, but i can say that i haven't had any disconnection issues while P30p was not moving while connected to car.
But, when i moved phone for any reason, it would lost connection occasionaly. I've concluded that was caused by weak connection, and haven't investigated it further.

well, In my case it seems to be a cabling problem. I bought 2 high-quality cables, 1-meter long and 2-meter long. I had tested the shorter one. This morning I tested the longest one and my P30 isn't able to connect AA.
I'll buy a shorter cable (0,3 or 0,5m) in order to test again..
