Major problem, Bluetooth music connection to car - Huawei Mate 9 Questions & Answers

Hi, has anyone run into this?
I'm used to play music from my phone to my car (Toyota Auris hybrid) over Bluetooth. Worked good with my LG G4 but with the Mate 9 it miserable fails. BT connects but it won't play anything.
There's loads of forum messages around since nougat came out, it seems to be an android 7.0 problem that seems to be solved in 7.11
Do you guys have successfully streamed in your cars over BT? Please let us know!

I'll test it when mine arrives as I use bluetooth also.

Some other info, it really seems to be widespread and only with cars. Will check if calling actually works, I was so busy with music I forgot to check.
Btw, I have a Pebble time steel and that now has a better and more stable BT connection across a longer distance than with the lg g4.
Update next day:
Car/phone BT connection is fine.
Audio suddenly worked after a few tries but no tags visible. Much in line with what others say. Really erratic behavior.
Same for my BT speaker, perfect connection.

Another update: It played audio only once. After some more digging on other forums it seems that Android 7 is the issue. A lot of cars won't play audio over BT anymore or just handle the stream only now and than. The connection is there, the song is playing on the phone, it streams to the car but there's no sound. Oddly when you receive a phone call there's no prob whatsoever.

My Nexus 6P on RRemix rom rooted with Marshmallow does this with 2017 Audi A4. Only thing that makes it come back is to hit the bluetooth icon in notification tray off and back on, and it syncs back up with sound. Try that? It might be a Huawei bug?

I had a similar issue on my mate 8. Spotify worked but deezer didn't in relation to showing what's playing etc.. it's likely to be nougat 7 as I've got a pixel xl and no issues with 7.1 at all over Bluetooth to my car. Looking at a mate 9 though as I miss the bigger screen

I have had issues with my S7 Edge where everything connects up and all seems normal but when it plays it either delays before sound works right out of car speakers or you have to do a dance of connecting and reconnecting before sounds works properly. Also think I recall similar glitching with my previous car and my previous android phone but maybe it was previous phone (Nexus 6P) and current car (2015 Nissan Murano Platinum). Only regularly ever play podcasts in car from Beyond Pod app, BTW. Occasionally play something off YouTube but don't recall it glitching.

I have a Japanese 2014 Mazda Demio, and my Chinese Mate 9 (MHA-AL00C00B109SP01) connected, played music no problem, over bluetooth. The artist/song name shows up. But it doesn't support browsing the song library like the iPhone or Galaxy S7 did.

I also have issues to connect my mate 9 to my car (Renault Laguna 3 from 2011). I simply do not succeed to connect the phone to the car: when I try to connect, my car gives me a 4 digits pin number to enter into my phone to establish the connection, I try to connect to my car from the mobile, the box to enter the 4 digits opens and closes before I have the time to enter the digits with a connection error message.
I suspect a software bug on the bt connection with pin validation on the mate side. I can connect without issue to a standard Bluetooth speaker.

I think some cars, maybe many, just have suck computer systems. It is why I always laugh at the idea of self driving cars - like these same morons that make these terrible in car computer systems will be worth trusting to drive you around.

I also have issue on Bluetooth with my Renault Megane 2009
I had to choose nomade device to pair my mate and I have some problem on mp3 play-back that suddenly stop where has it continue on music player.
It seems to be better since I install A2DP switcher from playstore but don't know why

So I have had this issue since I got the phone yesterday and just got it working in my 2012 Toyota Tundra.
Settings > Apps > hit the 3 dots > Show system processes > Bluetooth Share > Force stop, clear data. After that try pairing your device, mine has stayed connect with frequent breaks for 5 hours today

No issues with 2 of my vehicles.

I'm having no issues at all. I'm connecting to a Tune2Air bluetooth adapter ('11 A4 doesn't support Bluetooth streaming).

same issue with Pioneer Android Auto unit.
Sometimes it works out of the box, sometimes music plays (as per screen indicators) but no music, sometimes music plays for split second and stops.
disabling/enabling BT helps
no issues when phone is connected over usb with android auto

Same thing with me as well. I have reached out to Huawei but no response. I have a US version

Just got a new Huawei Mate 9 from Optus Australia. It would not connect to my car bluetooth although it would connect to two bluetooth speakers I have. Optus technical support finally resolved the issue by changing the car bluetooth PIN from 1111 to 0000. Looks like a Huawei bug in that it can only connect to devices without a PIN or with a PIN of 0000. Checked my speakers and one has no PIN and the other has 0000 as the PIN. Hopefully Huawei will fix this.

I have a recent Japanese Mazda, as well as a gear s3 or a Huawei watch connected at the same time, and no issues with Bluetooth at all with any recent Huawei firmwares.

My Fabia plays over BT just fine, Android Auto plays it fine too.

I previously reported no issues, but now BT is very problematic. For me, it seems, the issue stems from multiple connections. Before I needed two bluetooth connections in my car: one to the car itself for phone calls, and one to a BT adapter to stream music to the car's audio system. A couple months ago, I added a Huawei watch to the mix, and things went south. Typically I'll put my watch on in the morning and it will connect to the phone no problem. But when I get in my car, it doesn't want to connect: the car itself is not connected at all, the phone reports that it's connected to the BT streaming adapter, but no music plays through it. If I turn off BT on the phone and turn it back on, typically that will fix the streaming, but not the phone call connection. The phone will report that both the streaming adapter and the watch are connected, but not the car. If I click on the car connection, it will then connect. The watch connection in the list with then lose the "connected" status, but strangely, it stays connected.
So, I can't get three devices to say "connected" in the BT device list simultaneously, BUT if I turn BT off then back on when all three devices are available, THEN manually connect the car connection, all three will work, even though only two of them will say "connected".

In-car bluetooth won't auto-connect

Running the AT&T Variant and though audio and controls work fine in my car once paired the phone is not pairing upon seeing my car stereo.
My LG V10 worked flawlessly in this regard, usually withing 10 seconds of starting the car.
I've tried bluetooth auto connect and tasker but they only work if I toggle bluetooth while the car is on.
If I toggle bluetooth without either of those installed I just get the pop up showing there is a device available and it has about a 30% success rate at connecting.
There is also an issue every few times where even if it connects the skip buttons do not work and no track title is displayed.

I tried Samsung Music and Play Music. I verified Media Audio under BT was enabled. Mercedes Benz 45 AMG.
I have a Toyota and it connects flawlessly, T-Mobile variant. I can even go to the car while it's in the garage and leave my phone in the house and it's still connected to the car.
Strange, mine connects instantly (Ford Falcon - Aussie car).
Mine will connect with my car (Kenwood unit) flawlessly. I have to fiddle with it in my other car (Jeep with UConnect), while the wife's S7 works with both.
I've yet to figure out how to get it to auto open Pandora or anything when it connects. My Note 4 and LG V20 both did this seamlessly
Appears to be a "known" issue with S8 - see this thread : https://us.community.samsung.com/t5...id/GS8QA/highlight/false/page/1/thread-id/299

I've tried so many times. even reset cache, Bluetooth cache etc. It adding and then disappearing from both- car and phone. I think it is got something to do with contact sharing but this box never pop out.
I had this problem with the S6 and my HTC Stereoclip (BT to AUX adapter for cars), I had to manually pair it every-time and it was one of the reason why I came back to HTC, now I got the S8 and apparently it's the same problem.

Unfortunately, it won't happen. Samsung phones haven't displayed metadata on Civic stereos since the Note4. It's something about Samsung's custom Bluetooth stack when they upgraded it to Bluetooth 4.0; it doesn't offer full backwards compatibility. It will connect and play audio and even respond to controls via BT, but no metadata. And those apps that circumvent the issue by transmitting metadata in an alternate way, none of them work. We Samsung/Civic users have been fighting with this for a few years now to no avail.
And Honda doesn't put out updates for their stereos, so nothing will ever be fixed from their end. The only "solution" is to get a different stereo or a newer car. Or a new phone.
That's the worst part – every other phone works fine. iPhone, LG, Motorola, Pixel... It's just Samsung phones that don't play nice with older Honda stereos.
I am having an issue where call audio and contacts work between my T-Mobile S8 and Kia Optima EX 2012 with the Navigation/Infinity system, but no Streaming audio. There is no option on my phone for it, and I can Enable/Disable Streaming Audio on the car, pair, unpair, try different combinations, even factory reset the head unit and the Bluetooth on the head unit. Nothing so far. My car does show what's playing, but it still only plays through the phone and I can pause, skip, etc. from the car.
Anybody else had/has the same issue?

I know you posted this a while ago - but I have never had issues connecting blue tooth to my personal car (BMW X1) - I also travel heavlily and I have never had issues connecting to a variety of different rental cars, Fords, Kias, Toyota, etc.
Hope you found a fix or got it working
Stock stereo in a 2014 Toyota FJ Cruiser. I have no problems connecting, streaming audio, or making phone calls. My audio streaming does play with a lot of cracks, but it still plays. I might mess with EQ settings but I haven't had a chance yet.
2015 WRX with stock stereo (no nav, non-Harmon version). Here are the seemingly random issues I have with bluetooth:
- Connects fine most of the time, but will sometimes connect and the audio will be muted and requires me to pause the track on my phone and then press play.
- Audio will cut out at times and revert to playing through the phone's speakers, but the phone will still be connected and call audio will play through the car speakers and I can still control the track next/previous with my steering wheel controls.
- Audio will not connect sometimes when my wife is in the car wearing her FitBit, even with my phone's auto discovery turned off and nearby devices turned off.
- Track info sometimes gets stuck on the currently playing track and will not change until the car is turned off, the app is closed and process killed, and connection is made again.
Like I said, these issues appear to be random and seem to get worse when someone else is in the car with me or when I'm wearing an Android Wear watch. I've played with every connection setting I can in my phone but I'm sure this all boils down to it being a crappy stereo system. Nothing like being on the freeway during the beginning of a long commute and having my music cut out on me and having to switch back over to the (ugh...) FM radio.

I have the same issue. Sound is clear, music plays fine, wheel commands work fine... even the contact list, which only showed partially (200 contacts or so), now shows all of them...
But Title/Artist/Album do not show up, only says Samsung S8.
How do I enable the metadata?

As I outlined in my post, you can't.
Why not?
I have the same issue, calls work, changing track, music playing, good quality of sound, contact info, full phonebook (on the S2 it was just 200 contacts or so).... but no media metadata! This is software issue and it seems that in other units than the Civic (maybe post AVCRP 1.3) it works...

Connecting to Multiple Bluetooth Devices at Once?

Coming from the Galaxy S8, I was kind of disappointed to find that the Pixel 2 apparently only connects to one Bluetooth device at once. For example the phone will only connect to my car but not my headset at the same time as the S8 did. I like having that because when you don't want to take calls on the car speaker you can just send the calls to the headset without much issue. Is there anyway to get the phone to connect to multiple devices? Any mods that are available to get it working?

I've not figured out a way. In fact, as of the 8.1 update it made my bluetooth worse. When I connect to a BT device, rather its my headphones at the gym, or my car, I have to dial something and hit "dial" on my dialer. When I do that it makes the hangining up sound and then is free to be used for other things. Quite frustrating, really. :crying:
I had my p2 connected to an aftermarket head unit in my vehicle and set it to media only, connected to my Bluetooth ear piece for calls and shared my internet via Bluetooth to my PS vita at the same time. You just have to play with settings for each device.

I have wondered if its an issue with a mismatch between the two bluetooth devices.
It looks like this has been addressed somewhat in Android P. I am running the beta that was released yesterday and the device is now connecting to multiple bluetooth devices. There is a quirk that requires you to go into the bluetooth menu to change the current active device (Think it might have been like that on the Galaxy too) but it does maintain the connection to multiple devices now. It does automatically switch when you turn off one of the devices, such as your car, so this is definitely progress on this front I think.

Is the V10 also experiencing bluetooth problems?

Is anyone else here having a problem where bluetooth switches to loudspeaker when playing music?
I want to find out if this a general EMUI 8 Android 8 problem or if it is specific to the Mate 10/Pro.
For more details, here is the original issue thread for the Mate 10 Pro:

No Problems,Bluetooth works with headphones as long as you hear
Yes, there is such problem.
Wifi and connectivity speed drops even when Bluetooth module is on, without any devices connected, and becomes hardly usable.
Thus if you intend to use any Bluetooth devices together with WiFi, this is hardly a device for you. This is especially the case if you intend to use any of the smart watches of fitness trackers, that become hardly usable due to the repeated disconnections.
I don't know if this is a EMUI related problem, or not (installing Lineage may void my warranty, and i intend to return the phone), but the problem is quite persistent.

I was looking for some answers to my problem and I think this could be related... As you mentioned, when I have bluetooth connected to my earphones, the wifi connection speed drops a lot. It depends on the router though... I have a Virgin SuperHub 2 (UK) and it drops to 4-10 Mbit/s or so... I have done some test at work with a Netgear 6800 and it something like:
No bluetooth: 90 Mbit/s down / 90 Mbit/s up
Bluetooth connected to earphones but not playing anything: 67 Mbit/s / 90 Mbit/s
Bluetooth connected and reproducing music: 27 Mbit/s / 80 Mbit/s
Just checking the speed tests on my phone with the superHub 2 at home, it drops to 7 Mbit/s if it's connected to bluetooth and at around 100 Mbit/s if it's not...
Is there any software fix for this problem or is it a hardware problem?
Thanks!
I've ended up returning the phone, as I use a pebble watch and a fitbit m the time, and a headset in the gym, and then WiFi became intolerable.
I really liked this phone, but after 10 days of looking for a solution I've ended up returning it.
bluetooth phone calls not working
The problem is bluetooth audio for phone calls isnt working, i tested this
in 3-4 vehicles as initially thought this could be problem in the vehicle.
However i noticed the same issue in all vehicles. So this is definitely not
a vehicle issue. the phone audio on calls isnt routed via the vehicles (pairing is fine) -
however if play a song through a music player on phone, it works fine.
i have tried restarting phone several times and also deleted all pairing
and re-pairing the devices, i deleted the bluetooth data/cache as well but
no success..
Anybody have this issue on the honor view 10 ?

I further tried resetting the network settings, still same problem, hi care diagnostics tell me bluetooth is fine..strange!
I am on B160 and no Problems with Bluetooth or Wifi at same time enabled.I test on 2 Vehicles calls works and play Music with the View 10.I test with Youtube over Wifi with Bose Headset over Bluetooth,all working without any Problem!
Hm, I use BLK-L09 and I didn't notice either of those problems. Bluetooth calls work beautifully with my car's built-in bluetooth thingie and I can use WiFi with no problems while using my Mi Band 3. I use Carbon ROM though
I'm on a BKL-L04. I have not experienced any issue at all with bluetooth. I have an LG Urbane connected all the time. I stream music in home and in my vehicle and bluetooth has never caused me any issue - even with wifi on (and wifi does not slow, at least to my perception). Times when I've used my bluetooth headset, I still haven't had any bluetooth issues. (I came from, and still own, an Honor 8. I could barely leave the room with my headset connected to the Honor 8 before the signal would start dropping. No such problem with the View10. In fact, I have much more range in my house on my headset on the View10 than I did on the 8). My View10 is completely stock, no root.

Hi my problem with bluetooth started all of the sudden , it was working fine all the while - it isnt anything to do with using with wifi.
The problem simply put is bluetooth pairing and song streaming works fine, but through bluetooth phone calls audio isnt working - very strange!

Bluetooth issues on Oreo 8.0 & 8.1 update

Hi,
Since the Oreo initial update (8.0), when playing Youtube musics in my car, the title of the videos are not synced with the radio screen (a VW Passat). The first video played, the title is correct but from that point it basically stops updating or shows a previous played video title and not the correct one being played. On Nougat it worked perfectly...
So, I heard that Oreo 8.0 had some Bluetooth issues that Google addressed in Oreo 8.1. (you can imagine my question, right? ). When will Huawei release the update to our Mate 9?
BTW, anyone having Bluetooth issues with Oreo 8.0 that would like to share here?
Txs.
I've been having BT issues since the Oreo 8.0 update as well. For me, I use a BT to FM modulator for my car. Used to connect to it with zero issues before update. Now since, sometimes it won't even connect unless unpair and re-pair the device. This does not happen with any of my other BT devices oddly.

In Developer Options I noticed there were options to change Bluetooth codec and bitrate. I have no idea if this will help, but it might be worth a try.
I get a crackling sound (BT headset), but sometimes also when I'm connected to the car in phone calls only, both ends of the conversation. I think my issue is more with an overloaded system at "quitting time". AT&T doesn't have enough towers in my area.
Had a BT issue with our car today (2014 Kia Rio). It failed to pick up when I told it to connect. ( Phone said connected but car didn't follow suit).Deleting the pair from the phone and the car plus a reboot fixed the issue for me. Sitting on B366 with stock everything.
My experience has been the opposite, running 8.0.0.366 (C432) with no BT issues. No issues now, no issues before under Nougat.
That includes connecting/streaming to cheap whiteline BT speakers, Sony BT speaker, Bosch and Clarion car radios, LG TV Soundbar, Xiaomi BT car lighter adapter, Gear S3 Frontier, Xiaomi Mi Band 2, sending files to a P20, sending files to a 2014 MacBook Air, etc.
All flawless, no disconnections even after extended periods of time (1h30 streaming continuously), no drop in sound quality, same long range.
