Hi together,
during the attempt of acquiring data from the mobile P20 Pro (CLT-L29) (Android 9 - Security patch level 2019-10-06) by using the ADB (USB Debugging was activated), the USB-Mode was automatically changed to "Charging Only" instead of the preselected "MTP Protocol".
Is doesn't like that it's a matter of cable. I thought of security issues.
Maybe somebody has got an idea ?
Best regards
Simon

Hi all
I have a question regarding the p20 pro and android auto. Whenever I connect the phone it automatically switches from file transfer to charge only in the usb setting. I've tried enabling developer options-turn on USB debugging and changing the usb settings in developer options to MTP. Nothing helps. As soon as I connect the phone, it reverts back to charge only. Anyone have any ideas?
Thanks
Try turning on Bluetooth. Works for me.
I have a Huawei p20 pro and waiting for a car with Android Auto.
Someone told me he is able to use Android Auto on the same car with a Samsung Note 9 with no cable!
However i do not intend to change the brand. Anyone managed to do it?
The spotify opens and works with no cable but that is it all

Did you check this setting? It should set the default: Settings -> System -> Developer options -> Select USB configuration
Does it actually affect any AA functionality? I don't remember using File Transfer with AA and everything worked great.

I don't think AA supports wireless functionality right now, maybe he talks about music apps.
I asked and he says maps are working. Some mirror thing. And no root
Hello, everybody
Before I did the update to Android 9 on my Huawei P20 Pro, AA worked fine in combination with the Opel Intellink. Unfortunately, this has changed to a disadvantage since the update. As soon as I connect my mobile phone with the USB cable, the system asks me which USB option I want. So far so good.
But now it comes: As soon as I activate "Android Auto" in the Intellilink 4.0 settings, my phone crashes and tries to reboot. I already tried everything possible:
- other cable
- AA de- and newly installed
- Bluetooth newly paired
- USB debugging enabled (developer mode enabled)
- USB option set to MTP
- Wipe Cache partition performed
nothing helps.
Even if I don't have AA installed it crashes.
Does anyone have this phenomenon too?
Without activation this is not a problem. Bluetooth also works here.
Many thanks in advance for any suggestions or solutions.
Greetings Finrok
Me too - solution please?
Same here. Working just fine before the update. Now whenever I connect the phone to the car via USB it crashed and reboots. Tried the same as above but I can't see a solution.. I've managed to get it working since by uninstalling and unpairing the device. Plugging it in and reconnecting. But as soon as I unplug and go again next time it crashes again and reboots as before.
Not an issue with the cable, cache or Bluetooth.
May also be worth noting, I also have a p20 pro. Brand new in November
Has anyone figured it out? Please!
Was it OTA update or one of the methods from the forum (eRocovery, OTG)?
Is factory reset an option for you?
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

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?
I've managed to get Android Auto operational with my S10 and 2018 Civic. Initially I had trouble with it but some info on Google that suggested it was related to the USB connection mode and it was suggested to switch to developer mode, enable USB Debugging, and then USB Tethering as the default connection style. This worked initially but for whatever reason is does not remember the setting. Even if I select it as default. Every time I remove the phone from the USB or turn the car off and reconnect I am required to pull down the notification screen, select, USB options, and reselect USB tethering.
For whatever reason my selection of making the USB tethering the default connection type is not sticking. It's a pain in the butt to have to reset it every time I hook the phone up in my car.
Any ideas how to fix this?
Hi,
neither my Xiaomi Redmi Note 7 (xiaomi.eu beta) nor the Xiaomi Redmi 5 (stock Xiaomi) of my girlfriend can successfully connect to a new VW Golf 7. Both are running latest MIUI version, everything up to date. Data connection is enabled, USB Debugging too, we tried several cables, no Dual Apps. Once a phone is connected and Data Connection is chosen an error is displayed that a connection is not possible, USB then switches back to charging.
This is very frustrating. I found many reports about problems, most of them could be solved by using different cables or disabling Dual App. Both Xiaomis should work with Android Auto and App Connect, at least that's what (some) people claim.
Any ideas what to test?
I use AA on a 2019 VW Polo with my Mi 9. I dont choose data transfer, just charging is enough. You need to download latest AA app and i dont have USB debugging enabled because data transfer with USB debugging always causes trouble.

I had the same problem on my mk7 jetta and in my case it was caused by having the USB modem activated on my phone (I often use my phone as a WiFi USB modem for a desktop computer not equipped with WiFi card). Turning back every USB option to normal/off did the trick for me. USB debug is not required.
Did you fix erro?
Helo, did you fix erro? I'm with the problem like you!
