Mate 20X EMUI11 and Android Auto - Huawei Mate 20 X Questions & Answers

Recently I installed the MMI interface into my wife's vehicle, the MMI brings the Android Auto to vehicles, where it was not supported from the factory
https://f30.bimmerpost.com/forums/showthread.php?t=1675929
After some struggles it works pretty well with my wife's P20 Pro, however with mine Mate 20X I usually get the central section in the car's display black - see the picture. and only left and right are showing the phone is connected. Usually the only remedy is to clear the AA data to initialize it again, then it works very well until the car gets sleeping (the MMI is switched off the power) and starting agian (the MMI boots from switch off)
What I did:
I bought the good cable at the begginning - and with my wife's P20 Pro its working almost always.
I checked in android dev options the usb debugging - it was switched off during the time we have the car ready for AA (saw in some forum the usb debugging has to be off)
I changed in AA dev options the video resulotion to 720p (default value is no option selected) - no impact, I got that hint from MMI forum
The pictures from show events when my phone was working - even the dark mode when car's light are on and the full set of my AA apps. I tried 3 most recent versions of the AA from APK mirror, because in our country the AA is not enabled in play store yet. I think the only difference between versions I tested (but I'm not sure it was caused by those AA different versions) is the indication of the phone's battery and phone network might be in the right section or center section of the vehicle's screen.

The main use cases for us:
having the phone content on the car's display and controlling it by car's controls instead of the touch screen
Waze (real time optimal route finding based on the current traffic and speed traps)
hands free
some music/video for 4 years old daughter
1 - 3 are must haves, the 1 is so much more convenient than just having the phone somewhere, we drive every day

Sony Ericsson LiveView™ Issues

Hey is there anyone out there also having strange connection issues on Sony Ericsson's LiveView ?
I'm running a HTC Hero with the latest cyanogenmod.
I can pair the device in the setting. The display always just displays 0:00 AM.
when i try to connect in the software it always is listed as disconnected. when i try do build a connection from liveview side (upper left button) it's showing an animation that it's connecting to the phone. the led on the top left starts turning green, then the display freezes and it falls back to displaying 0:00 AM (and not being connected).
when i tap on the listed device in the software (guessing that you connect it that way) the second line saying "disconnected" disapears for a bit, around 5 sec., and then comes back as disconntected.
i once but only once managed to get it working somehow. DON'T ASK HOW, MAGIC, Star constalation, nobody knows, i randomly hit connect on both sides and it turned out to work that one time.
when working the time display on liveview show the actual time on the phone the display and you get all the notifications you could wish for. But at some point i had to reboot and it work never again =(
i had in mind that the my bluetooth headset (also sony ericsson, mw600 nice piece btw., loving it) might intervene somehow but it worked nicly, both at the same time.
please does anyone have an idea?!
really getting frustrated, had such high hopes in that device and really was looking forward to write some cool apps and plugins for it but now ...
First off where did you buy it?
it will release on November 19th in UK .. How did you get it ?
I was thinking the same

Bet five bucks, it's some kind of Chinese clone.
Got it from phonehouse, ordered it from the German page got it instantly. So i guess no help just yet ;(. And se support isn't that supporting at all
Prooflinks, please.
Sent from my MSM using XDA App
feel free to order it from

got mine since yesterday, bought on phonehouse website in France.
Several issues for me to , on HTC Desire / Froyo 2.2 non rooted
I didnt fond any trouble to connect it to my phone but then :
First day of use : several crashes and slow down of my phone
forced to remove the battery of the phone... bad feeling
Second day of use : Left physical button is no more responding !!!
(my device falled down from my desk, 1 meter high...I wonder if it comes from this)
Impossible to empty the liveview's cache, even if the application says "all notifications are now removed" they still are in the device memory...got almost 200 since yesterday.
what is working now ? :
all facebook & twitter notifications, calls history, RSS, volume up, volume down.
I didnt received sms yet so i cannot tell, and track seeking does not work.
I wrote to SE about my left button who doesnt work any more...
My order should be here on Monday. Can't wait
Same big problems as above.
I had already posted this in another thread before finding this one.
I am in Paris, bought it on Phonehouse.fr (59 eur w/ free shipping).
- I'm on a HTC Desire Orange FR with Android 2.1
- there are 2 apps to be downloaded from the Android store: LiveWare manager (this seems to manage the connection and the plugins) and LiveView (the actual tool to manage the device).
- the pairing is immediate (in Android's Setting / Wireless / BT) but not the connection, and somehow I got to it only after random manipulations and attemps.
- but the device connectivity from LiveView software comes and goes randomly. When I managed to get it to work it stayed on for about 1 hour. Then I went to the toilet, lots BT connection, came back, no way to restablish it now.
- I've NOT found a repeatable way to connect to the device. Several times the LiveView software crashes, or it severely slows down the phone to the point where only removing the battery could save me.
- I had time to test call and sms notifications from phone to device, however all actions from device to Phone did not seem to work, or they even make LiveView hang. This concerns the music player controls (not working at all), and some feature where from the device you should be able to display the lost calls list on the phone display (but as I said - it hangs the LiveView manager).
Update.
I suspect some problem with the phone Bluetooth software.
Now I cannot make the phone discoverable anymore - tapping the "discoverable" checkbox in the BT settings does not work. Tapping 3-4 times makes the phone hang: it reboots, but it becomes extremely slow and laggish. Battery removal needed.
SE stated on their webpage (though they removed that, only a * marks this) that music control is not compatible with Desire. Sad thing.

That must be it. At least I found out the volume control works (media volume only), but not the play/stop/next/prev track.
LiveView hanging
On Galaxy S with Eclair. Paired and connected OK. SMS alert worked fine. After quarter of an hour though LiveView hanging. I might had tried to get to the home tile and kept select button pressed which could have tried to start the music player, not sure nor intended.
Left button Green LED on at all times, screen of LiveView shows green Sony Ericsson logo. Cannot get LiveView to do anything. I am hoping it'll run out of battery and reboot! Trying to pair with it after phone reboot unsuccessful.

Managed to bring it back to life. Had to hold left button pressed for a looong time till eventually (20sec or more) screen powered off. Then reset via holding left button pressed for 8s+ as per troubleshooting instructions.
cpu goes wild
Huge problems with LiveView on Galaxy S with Froyo.
Aside from dropping connection a lot, it periodically renders the phone unusable requiring a reboot.
top shows btld consuming 90 - 110% of the cpu:
Code:

[Q] LiveView
It says on the specs it requires Bluetooth 2.1, my phone has Bluetooth 3, will it work?

I have exactly the same problem on a Desire Z. It seems to me overall that the LiveView is an unfinished product ATM. I hope for a software update very soon!

Android auto

I'm planning to buy this from rn4. Someone says that android auto is faulty. Truth?
On my Seat Ateca I used, without any issue whatsoever, an Asus Zenfone 3 for over an year.
Unfortunately, my Xiaomi Redmi Note 5 Global is a pain in the ...
I have tried tons of different (quality) cables, including the original Xiaomi one.
Tried with developer options, MTP, starting AA before connecting, after connecting, while connecting, opening AA, closing it, sitting, standing, breathing, laughing...
Never found the reason why, once in a lifetime, it decides to work. It took me from 5 mins to 20 to have it running.
A real pain!
Disable dualapps
In my case I could connect with my original cable, no issues, you just need to disable the "dualApps" thingy, but I have other issues.
1- Waze when using the android auto, can look for directions start navigation it even calculates the time and traffic, but the position won't move, on the map, my position is always displayed on the starting point, but I get audio notifications, ODD!
2- Spotify, every time I connect the cell phone to the android auto, I'm getting a screen that says "Update something" and I cannot use Spotify unless I restart the phone (even if it's working fine on the device)
A redmi note 5 new, I used android auto on a Zenfone 3 for a year or so with no issues.
I figure out how to fix these issues, more or less:
1. Be very sure that for spotify and waze, the battery rules are set to allow everything (not automatically optimized). Our phone use to shutdown background applications for battery optimizations (so, no more waze gps location). Same for spotify.
2. Enable for android auto, spotify, whatsapp and waze the automatically launch on start.
hi, I have same problems with my RN5 Global and my Ateca. tried lot of Roms, all of them needs up to 10 minutes to connect. I have tested other phones, S7, A5, no problems. only RN5 have this problems. it seems to have MTP issues in the firmware

Issues with new Pixel 3 connecting to car

So I've just switched back from IOS to Android and picked up a Pixel 3 XL with the 1-day sale. I tried setting up Android Auto though but I can't get it to work properly. I can connect and add my car (2017 Kia Niro), but after I try to select the Android Auto icon on the head unit it crashed and keeps flashing "Phone is not responding" and "Reading USB" over and over. On the phone, it still says connected to the car and shows the green notification bar suggesting Google Maps is in use.
I've tried using an older version of AA, but it gives an error unless I update. If I try to connect, not press the icon on the head unit and start playing Spotify, I get 1-2 seconds of audio through the car but then it crashes again. One time I got as far as launching and selecting the navigation tab until it crashed. I've briefly talked to Google support and they requested a bug report which I've sent. I also tried updating to the Q beta to see if that made any changes. I've used 5 different USB cables with no luck.
I didn't have any issues with Apple Carplay, and I also tried a very old Samsung phone (micro-USB) successfully so it shouldn't be the car causing the issue. Does anyone have any tips on what I should look at? I've done a factory reset, cleared all cars, toggled the AA setting on the head unit but nothing makes any difference. I'm pretty reliant on this functionality, so if it doesn't work I probably will be switching back to my iPhone.
Odd behavior. I've had a few issues with AA on my 3XL on Q beta 2 (patched), but none like that. I have a 2016 Chevy Malibu and most of the time when I plug it in I get video but no audio. Pressing play on Spotify does play, but no sound comes out. Disconnecting and reconnecting USB a few times fixes it. There are intermittent skips in the music where it cuts out for a second and comes back. The screen flashes black at times when a notification peeks on the screen like when the song changes. Overall it works, but Q beta brought some bugs. It was mostly OK on P. I believe the no audio started on beta 2.
Have you looked at the developer settings in AA to see if any toggles might help? I think you can go to About and tap the version 7 times, similar to enabling Dev Options by tapping build number in Android system settings.

Thanks! I'll give that a shot when I go to my car later. I forgot about the AA dev options, it's been so long since I've used Android. Hopefully, if I do get it working I don't have the audio issues you mention by switching to Q else I guess I'll need to revert back to P.
I just received a new Subaru, and I couldn't get AA to open at all. After searching, a common denominator was the cable used to connect the phone (my car requires a usb connection). I tried 4 different cables before I got it to work.
The one that worked was an OTG cable, no longer available on Amazon.

I have 2 Subarus and had issues with AA until I figured out that I needed the head unit to come up, have the I agree screen dissappear, and then connect the phone. Works every time. Plugging the phone in before booting the head unit is hit or miss.

Try waiting for your cars head unit to come up before connecting the phone. Ideally bluetooth wilm be connected before you connect USB.
Well, turns out it was the cable. This was 4 old supposedly good cables from a few years ago, along with a new one from Best Buy. Picked up a new Insignia USB C cable where the reviews mentioned success with AA and it is working. Bit of a headache but good news.

Lenovo z2 plus various issues

So I have been using Lenovo Zuk z2 plus from 2017. The phone worked fine till 2019 with some minor issues which all phones have. But from August 2019, these are following issues I have been facing:-
1. The app switching option which is a basic feature in all mobiles has been not functioning so I can't multitask in this mobile.
2. The quick panel which comes from bottom is not functioning so I have to start WiFi, mobile network, etc options by going to settings.
3. The WhatsApp application stops working after 2am ie it force stops and don't function, I have to start it then it loads messages.
4. All Google apps stopped syncing and don't work eg I cant download any app from playstore, my mails don't come in Gmail app, I can't use Google pay, etc.
5. My phone don't charge after plugging in to charger and I have original charger. After connecting it shows charging and stops and then heats like hell. Sometimes it drains very very very fast and switches off while charging and many times 0% battery shows and phone switches off and then switches on shows 0% battery and then again switches off. This happens many times.
6. My keyboard's 3rd line don't work. When I touch that line, it types upper line or lover spacebar.
7. My phone heats like a oven with using, without using, charging, etc.

Since it has been 3 years now, and from point 5 & 7 the most possible cause is your battery is dead and needs replacing..
It usually costs around 2000 rupees to change from authorized service centre.
Point number 1,2 & 6 could be due faulty touch screen.. You can download screen test app from play store to test and check if there are dead spots.. If it is touch screen issue and it needs replacing then it will be another 1000-2000 rupees approx depending if do original or not..
In this situation I would suggest you to go for new phone as there are many options available like redmi note 8 or realme 3 or 5 series which will not cost you more than 10-12000 rupees.. Which is around the same price as of this phone..
If you do get battery and screen replaced under 4000 then for rest issues I would suggest you to flash custom ROM as you would get a much better ui and latest android 10..
This phone is good to go for atleast 2021.. We have been receiving custom ROM from android 6 and hopefully with developer release of android 11 beta 2 already happened we should have android 11 support soon for z2 as well..
point 6 happened to me earlier and yes this is touch issue which can be fixed by electrostatic effect i.e. you can use lighter (for gas burner ignition or the one which can be found in cigarette lighter). Just provide multiple shocks at non touch responsive area, turn screen off, on and problem solved. believe me this trick saved my money also.

Question Android Auto

Is Android Auto working for anyone? No matter if I connect it to my car or use wireless AA, it starts and disconnects right away and just keeps doing that over and over. I haven't been able to get it to work with anything I found online with past Samsung phones that had connection issues. Any help with this would be greatly appreciated.
Same issue here with my 2019 volvo xc60. Car briefly shows it's going to connect then says "reconnect device". Phone will display the initial setup screen but when you hit next it flickers something and vanishes. Using cable.
All updates installed...
Working just fine in my iX3 wireless. Not tried wired, but then never do. I am running 8.x.x beta though, might be worth trying that
Found The beta and sideloaded the update. No luck, same problem.
This really sucks.
Broken here too. I'm using a JVC head unit in my truck. Works great with my S22 Ultra, Z Fold3 and iPhone 13 Pro Max.
I've tried everything under the sun. No luck. Even reset network connections in case it was a corruption from migration.
Same here, 2021 Tacoma. Fold 2 worked just fine, now nothing.
AA desperately needs an update in general.
iOS carplay is so much better.
BUT! Not working at all is very, very bad.
Early users also reporting July security patch too so perhaps an update is in order. They usually smooth out new devices (aka shakedown) after a few months so fingers crossed.
Just rec'd my G4F today, and also nada for me in my 2015 Mazda 3.
G3F works like a charm. This sucks.
How the fck could Samsung deliver a phone that has broken aa? WTF
Also broken on both my kenwood radios. fold 2 still working like a champ
No issue in france with my peugeot 208
Kia Sportage no issues....
No issue on e208
It's like the AA crashes before it finishes authorizing the permissions for the vehicle. I may try getting everything set up to pull ADB logs this afternoon and see if there's any clues there.
Solved it!
I went into apps, Android Auto, cleared cache + data (again) then I went to the battery option for Android Auto and set it to "Unrestricted". I'd already gone under the central battery options and set it to never sleep for Android Auto previously but that alone didn't do it.
Paired perfectly on next connection. After that I just paired it with my wireless AA dongle and everything is fine with the world again.
AA working fine with my GF4 + 2022 BMW M3.

Hello,
I just wanted to let you know that it worked for me. I was having the same issue. I have a 2020 Hyundai Palisade with the new Fold 4.. Thanks for posting the solution!!!!
Dave
I can confirm that resetting caches and data for Play Services a Play Store did the trick. Also AAWireless is working now.
I was going to reply and tell you all that if you have uploaded apps from the old phone you had to the new Z Fold 4 , there will be some apps that will require a clean start and date and cache probably will require it, especially AA. Getting my phone today (FedEx say it is on the truck to be delivered) and here is my part I am re-thinking the wireless AA.. I drive an Audi A6 with an after market module for Car Play and AA.. That worked fine with my S20+ so far. The screen in the car is not a touch screen , 8.5" lower resolution than the fold 4. I got the new car Qi mount for the fold 4 installed last night and it looks , even with the S20+ much more crisp and clean, not to mention a touch screen. I bet when the Z Fold 4 arrives today and I will have it placed in the mount open, the 950NIT , hi-res , will make my car screen look bad even more.. I truly think of removing AA from my phone, not connecting to the car although I can, connect only Bluetooth to have Spotify/phone use the speakers, and turn off the car's screen.. For less than $50 good car mount, WHY would I need AA? Controlling from the steering wheel ? Meh, I use Google Voice anyways.. Your thoughts, as Z Fold 4 7.6" hi res screen owners? I'll share my comparison between the two options after 2-3 days of driving around with an open phone, vs. Car screen..
