Flaky Bluetooth not auto connecting to car - Huawei Mate 20 Pro Questions & Answers

Hi folks,
I've seen a few comments on bluetooth on this phone but not this specific one. I have a Kia Optima with bluetooth and when I get in the car I expect my M20P to auto connect to the head unit. It seems very temperamental though, often not connecting at all. Other times it will connect and then randomly drop connection and reconnect. Has anyone else had this or know what might be causing it?
I'm currently testing if it only connects when I wake / screen on / unlock the device which it seemed to do on my commute this morning, but then a second time it still didn't connect doing the same thing.
I'm also checking with Kia if there is a software update for the head unit but i'm expecting them to blame the phone and Huawei to blame the head unit.
Any help appreciated.

Hi, I am experiencing something very similar. Very bad audio quality during calls, and temperamental connections with Bluetooth - disconnecting and re-connecting.
I haven't been able to find any solution, hoping to awaken this forum.

Same issue here - On 9.0.0.187
Volkswagen Golf 7 2016
Voice sounds like its lagging and like metallic treble
Also i notice with Spotify will streaming music that the display unit is out of sync with what i am listening
It shows the title of the previous song that i have listen not the current one

Did you ever figure this out?
My girlfriend just reported to me that her new 6T is not automatically connecting to her car like her old Android did. It's paired, but she gas to manually connect.

I have audio speeding up and slowing down on my Skoda Citigo bluetooth with Mate 20 Pro, its slightly better than my Galaxy S8 which used to continually drop connection.

9.0.0.266, Very flakey Bluetooth since this update applied. Used to be fine before this, now i get random disconnects from my Galaxy Watch,, by VW headunit in the car, and random drops of audio from my Freebuds 2 Pro.
Starting to get rather annoying

[Q] Let's talk Bluetooth problems

Hey everyone,
Has anyone noticed bluetooth issues? I've pointed them out in other threads, but they seem to be glossed over. I hate to seem like a noob by creating new threads, but I fear that the issue is being looked over by most people. I've read a few reports of people having issues with their phones connecting to their cars or headsets automatically. Has anyone else faced these issues?
I specifically cannot get my BT headset to connect unless I unpair and repair it everytime I want to use it. Sometimes even during a phone call the headset will drop connection and wont reconnect unless i turn it off and on a few times. For reference, I've tried multiple BT headsets and they all behave the same way. These headset's also work just fine with my Galaxy S2, just not with my S3 (international on XLE8)
No problems with bluetooth here and I use it a lot (HS3000, Logitech Boombox, PS3 and Wii controllers too).
No issues here. Phone sometimes doesn't pair automatically with the BT kit in my work car, but I've had that issue with my S1 and S2 in the same car so I'd say it's a problem with the headunit.
Works perfectly with the Sony headunit in my own car, and connects to my mate's fine.
ok, what firmware rev are you guys running? im going nuts not being able to use bluetooth here!!
somewhat related.
i often leave my sgs3 connected to my laptop via usb when i fall asleep. at morning, battery's charged 100% obviously and phone isn't hot.
last time around, i was listening to music via hm3700 bluetooth headset. then later turned off the bluetooth headset. i forgot to turn off the bluetooth on sgs3 and again fell asleep while it's still connected via usb to laptop.
when i woke up at morning as usual battery's charged 100% but the sgs3 was hot, not so hot but isn't anywhere the normal hot we're accustomed to.
connects automatically to my car's BT built-in system. Only needed to pair once.
Works very well with my Sennheiser PXC 310 BT.
If I switch on the headphones the phone automatically connects to it.
can everyone please detail their firmware/kernel they are using?
i am on XXALE8, with the stock kernel
I have problems on XXLE8 as well connect it to my car head unit and it acrually crashes the headunit after 5 mins being connected . After the heaf unit crashes 3 times it requires a pin code. Iphone 4, 4s and gs2 connect no issues.

thanks for your input, i upgraded to XALF5 and still having the same issues. this is frustrating!!!!
Oddly - my phone will automatically connect to my cars in-built BT system, but it won't auto connect to my Jawbone Era without switching BT of and back on....
I also have problems, with my build-in bt in my car. Have XXBLH3. Connect fine, but drop the connection 2-3min after. My SGSII have no problems
No Ringtone through Bluetooth
Okay here is my problem……I want my custom ringtones i have set for contact to play in my Bluetooth headset when a receive a call, not that dumb ring. That way I will know if I want to take the call or not because I can tell by the ringtone who is calling. Why would Samsung disable this feature. my iPhone 4s plays the ringtone I have setup when I get a call. Is there anyway to do this. I ride a motorcycle and I have a device called a Chatterbox that let’s me connect via Bluetooth to my phone so I can hear my music and talk and make calls while I am riding. On my iPhone 4s my music would pause my custom ringtone would play and I could decide it I wanted to take the call or send it to voicemail, then my music would start right back up from where it left off. Right now my Galaxy i717 and my Galaxy i747 (Note and S III) just play this annoying ring and I can’t tell who it is! Any have a fix or work around for this.
Hmmm, the sound on my cars bluetooth gets distorted and only a reconnect will fix, and more worringly sometimes the S3 will not wake up after disconnecting from my car and only a hard reset will solve it.
My S2 did pretty much the same thing.

Bluetooth Media Audio Connectivity Issues W/ T-Mobile V10

I really like this phone but can't figure out why LG Phones have so many problems with their Bluetooth Connectivity....
I have a New 2016 Honda which my V10 when I set it up works fine then.... if I leave the car with my phone and then return, the media audio portion of the bluetooth just goes into a endless loop of disconnecting... Phone calls are fine. But media audio only works the first time you go through the whole pairing process then won't work again until you do the whole process over again... When I had the LG G4, it did the exact same thing with my 2012 Hyundai until LG patched it....
Anyone else having issues with the media audio connection with their bluetooth? I've tried all the tricks like toggling stuff on / off, clearing caches, etc. Just hoping to see that it is not a random case of a bad phone but rather a "known" issues
Thanks! :good:
Exact same problem with a 2015 Silverado. Hopefully it gets fixed soon.
Yep
Same here as well.

I've got a 2013 Civic SI, works great. Must be a different Hondalink platform in the newer models.
This has been my big complaint so far. Every other phone I have automatically connects to my bt receiver when I get in the car, but I have to physically connect with the V10.
So i made a thread about this a couple days ago then no one replied and of course 3 new threads on it popped up.... anyways im having the same issue with verizon. I just purchased the NEX 4100 and phone calls are fine but audio doesnt work nor does android auto which a HUGE issue for me.... Im thinking about returning it because of this. I called lg today and they of course brushed it off onto pioneer which i will call tomorrow. What do you guys think should i get a different phone? I was also thinking of returning it next week and still getting the promo stuff then buying it again on black friday for a better deal? Are these issues normally patched quickly or should i not bother holding onto a phone that doesnt work with my new $1500 sound system that i intentionally got for android auto....

I have a 2015 Accord EX-L. Have not had this problem. Not yet anyway.
However as I mentioned in another thread, the V10 does not continuously update the signal strength meter on the car dashboard. Only when the V10's screen is lit. After it goes out, you can drive through deadspots and think you have 5 bars of signal. Until you press the power button which then updates the display in the car. Since I had the HTC One M9 up until this past Friday, I can tell you that it definitely kept the signal strength meter in the car up to date continuously.
Have a 2015 Chevy SS.. Had a situation where there was no bluetooth audio with the mylink system in the car. Happened once.. Has worked reliably ever since.
Luckily for me on my Subaru system the phone has always connected properly at startup. But the audio regularly skips when playing... not jut on my car, but on my bluetooth headphones I have as well, same thing with skipping issues. On occasion my car's audio will get completely disconnected while I'm driving as well, very annoying.
Used my car's audio and bluetooth headphones with my S6 and had zero issues with them. Must be V10 issues. Hopefully a 6.0 update fixes the problems, otherwise I'm trading in again.
I'm having similar issues, 2014 Kia Optima Hybrid, streaming Spotify via Bluetooth incoming calls don't stop the Spotify music automatically and the person on the other end cannot be heard. I'm coming from the Note 4 and it never had this issue. Any recommendations?
I've got a 2015 VW Jetta TDI manual and this is the first phone I've had that works properly. I've got the LG Tone Pro headphones too, and when I shut the car off it goes to headphones almost immediately. Vice versa too, and this is the only phone I've had that video syncs with audio or is maybe 1ms off.
My thinking is it must be different bt link platforms in the car, but we should all be on BT 4.0 by now. Sorry that it's not working properly for you guys. Keep complaining until they fix it. Customer satisfaction is their goal.
My 2013 Chevy cruze works perfect. Not any issues what so ever

I was thinking of picking up a v10 but this thread makes me hesitate for now. I have a 2014 Honda CRV, and Bluetooth music in the car is very important to me. I hope this gets fixed for us all

I'm having problems connecting to my 2015 GMC Sierra (GMC Intellilink). I can connect, connect automatically, make and receive phone calls, but the bluetooth audio for music DOES NOT WORK. Most of the time, when I try to play a song via google play music or Deezer, the head unit in my truck immediately goes BLACK for about 10 seconds, I hear a whirrr of an internal fan, and it starts back up disconnected from the phone. The phone is causing the head unit to fail & restart. Sometimes it doesn't restart. It'll show the progress bar of the music, as well as on my phone. I can pause, play, next song, etc. but NO AUDIO comes out. It's just dead silent.
I actually have my truck in the shop right this second to see if they can upgrade the software in the head unit, or figure it out. I'm sure they're going to tell me I'm S.O.L. I really don't want to have to return this phone. It's perfect, aside from that 1 issue, but I didn't buy a brand new vehicle to be plugging my phone into a headphone jack like a knuckledragger
It turns out the Bluetooth seems to work fine in my 2014 Honda with Hands Free Link. It takes maybe 10-15 seconds longer than my previous phones to auto- connect when I start the car, but it does it. Music sounds on par.

Same issue with my V10 in a 2013 FR-S. Between the Bluetooth and Fingerprint scanner issues I'm returning this Flag****...I mean Flagship phone.
There seems to be an issue with auto A2DP bluetooth connectivity even if Bluetooth is connected.
After I connect with bluetooth: Oftentimes, I will have to choose the "Chromecast share" app logo on apps and explicitly choose to "connect to a2dp device" - for 8tracks and youtube for example. For apps that don't have that "share" button, I will have to play out of phone speakers first, than go in to the bluetooth details section while connected via bluetooth already, select configure for the bluetooth connected device....than uncheck and check the "Media Audio" box.;The media will than usually switch to play through bluetooth device.
Clunky workaround. I've had to do this with nexus devices too and it seems to be an issue with android OS a2dp audio routing. I believe the blame is with Android versus LG. If a2dp worked on Samsung, it's bc Samsung patched the hole in android.
Have a VW Passat 2013.Was now problem with Bluetooth connection until yesterday. Have a V10 for a week, but yesterday it was looping in connection and unable to connect back did everything what you guys did ,no luck .Very disappointing
I have this issue and it's on every bluetooth device I connect to. I literally had to put the phone less than 2 feet from my head to listen to music... Hope a fix comes out soon

Z5 Compact Blueooth disconnection

Hi all,
i use my Z5 Compact for tracking my run with an Android Wear device (LG G Watch R)
I have several problems with Bluetooth. It works for some secs, then crash. After a min re-start works and reconnect....and so on..
When i use a cardio strip also the hr disconnects.
This is a video of the problem:
youtube. com/watch?v=YgA45nP8Nk4
Can you help me? I'v yet Hard reset it 3 times.
Thanks to all
I cannot offer help unfortunately but I am seeing similar things. And I am starting to think (hope, even) it is software.
My Jawbone UP3 disconnects continually and getting a reconnection is very hard, often involving a band reboot. I also have 4 TrackR tags which are randomly but frequently showing a re-paired message (smart lock device) in the status bar for no reason at all.
I've a Pebble Time but that has not been connected too much and seems ok, equally my Jawbone Jambox and MDR-XB950BT Sony headphones have been working without issue.
Possibly then it is only Bluetooth LE that is an issue (your fitness tracker would be that) and the three working devices are regular BT connections.
With luck this is something then that a firmware update will address. I hope so, because I'm bloody sick of buying broken hardware.
I use Bluetooth at various times throughout the day. I've never had a single problem with it! I am communicating with cars and obd2 systems though not low powered items like watches and headphones. Fwiw I'm on .152 firmware.
I am having massive Bluetooth Low Energy issues, I came to post about it but will do so here.
I have the E5823 unlocked in White. Android 6.0 although this started with 5.1. 32.1.A.1.163.
Basically I am concluding BLE is totally screwed on this phone, and I was about to send it back but realise the number of other BT issues people are having means it is likely not hardware on this one unit so perhaps software resolvable.
Jawbone UP3 loses connection continually, it occasionally connects and syncs, but I cannot force this.
TrackR Bravo tags work on occasion, frequently disconnected and randomly 're-pair' to the phone with no interaction (new BT device notification all the time)
Tile same thing.
Parrot Minidrone cannot be seen by the phone most of the time, it works on occasion.
All these devices are Bluetooth Low Energy. On the other side I have a Jawbone Jambox, Sony MDR-XB950BT headphones and Onkyo-NR626 Amplifier with regular old Bluetooth and all of these work, A2DP, atpX.
The only difference I noticed with 6.0 vs 5.1 is that TrackR can now tell the range by signal strength, something that always worked on the LG G4 Android 5.1 and 6.0. So I think the z5c started with issues and has not exactly improved.
Saying this there are known bugs in Android 6.0 and BLE, solved in 6.0.1. But right now I am super angry that yet another phone I buy is broken out the box. It never ends.
had BT issues, using a smartwatch (LG W100 G Watch).. but it was more frequent when used in combo with other accessories.
updating and restoring to MM 6.0 solved any issue.. so i managed to get well working, at the same time, smartwatch, cardio band, earphones and cadence/speed sensor (for bike).. all using BT LE..
before restoring and updating i got disconnections and glitchy music

Vivo 5 Bluetooth Issues with Sony MEX-XB100BT Car Stereo

Trying to find out of anyone else is having problems with their Vivo 5 Bluetooth connection to Sony MEX-XB100BT Car stereo or Sony stereos in general. I have tested my phone on a couple of neighbor cars (a 2013 Prius, and a 2015 Chevy Traverse with stock head units) and it the Bluetooth works fine. I went to Best Buy where I bought my care stereo and they were kind enough to let me swap out my head unit for a brand new one to see if that would work. Still same problem. Problem is....it pairs up just fine, but as soon as the music starts playing, it's sporadic and the music keeps doing this on and off thing like a bad signal to an FM station. I will look for a Sony Forum and post this same question. Just hoping someone has had the same problem and found a solution.
Mine does the same thing. I have a BLU vivo 5 connected to a JVC double din head unit and it acts like it has a bad connection or something because the music keeps skipping in and oit.

It's hit and miss as to whether the pairing from my Vivo 5R to the MediaCenter of my Toyota Aygo lasts 15 seconds or 2,3,4,5 minutes.
Useless!
Also, no texts will download, and incoming texts don't register on the screen.
There's a message "Would you like to add messaging?" which - when answering 'Yes' - returns the useless message :
"You may need to operate your device to allow messaging access."
Thank goodness I kept my trusty Motorola G [1st Gen] !

Bluetooth issue?

Quick question: is anyone having issues with Bluetooth stopping every so often while playing music? It does it on my Klipsch earphones & in my car (my only Bluetooth listening so far). What I've noticed is that it interrupts the music because it thinks it's in a call. If I press the button on my earphones that would end a call (or likewise in my car), the music starts right back up. It seems like an odd bug. Any thoughts?
Haven't seen anything wrong. I don't want to jinx myself but so far, it's actually working much better than my V20 was. Every day I'd have to turn my BT off and back on before starting my car or it might not connect the audio properly. Then, about once a week, a complete restart was needed. Haven't had to do either with the V30 yet.
V30 Bluetooth issues
I've had multiple issues with Bluetooth connectivity for a few of my devices come up recently.
For example, I'm getting delays in receiving notifications for both my smart watches, even though only one of them is active at any given time.
My Snap Spectacles was paid, but suddenly stopped transferring videos to the V30. I paired the glasses to my iPad, and videos transferred seamlessly.
The notification for WiFi Direct keeps popping up abet few minutes. Says something about running Bluetooth, wifi, and wifi direct at the same time can cause issues. Sadly, I couldn't find a toggle to turn wifi direct off. Even when I turn regular wifi off, it turns back on.
I have no issues with BT ... but, the sound issue is likely notifications.
Yup...Bluetooth Issues Here
So I finally have the LG V30. Generally a great phone. But I too have bluetooth issues. I hear static on calls made over bluetooth. Two phones, same issue. My G6 did not have this problem. When I (briefly) had the GS8 and Note8 this was not a problem. The funny thing is, when the phone is in my pocket with the screen off, there is no static. When I remove the phone from my pocket and wake the screen, the static returns. The bluetooth works fine for my podcasts and music. Weird. But reproducible. I use the BT in my car a lot (yes, I actually make phone calls on my phone )
So I was wondering if others have had any bluetooth issues.

Weird indeed. No problems here. I'm paired to a 2013 Audi, a 2013 Ford, and a 2017 Chevy, not to mention an older Plantronics earpiece. No problems -- all my calls sound normal, or even crystal clear in Verizon HD.
This is with screen on with Waze, Pandora, even Android Auto running.
No static for me either paired to a 2013 Audi with screen on and Waze running

Thanks for the responses. I can find no one else with the problem. Yet I had no issue with any other phone. I'll keep looking for a fix.
All of you guys with BT issues, do a factory reset and report back.

I did this on my first V30. A factory data reset did not resolve the problem. I am not sure if a reset will help with this one either. But I will give it another try.
I am having similar issues with the Bluetooth on the LG V30. When the phone is too close to the built in navigation screen/Radio in my vehicle, I am getting a lot of static. Only when making/receiving phone calls. When I move the phone 1 foot or more away from the center counsel of the dashboard the static goes away.
Went to the TMobile store where I bought the phone. They produced another LG V30 and connected to my vehicle's bluetooth. Same issue.
No issues when connected to music players.
Quite frustrating as I really like the phone.
I'm having BT problems. Calling is pretty much useless in my car (2015 Subaru), but music works reasonably well.
I'm getting continuous toast notifications about the phone connecting/disconnecting every 30 seconds or so, no matter what device. Very, very frustrating.

I'm wondering if you have the cheaper stereo in the 2015? It's the one with a small monochrome screen and manual knobs?
My wife has issues in her 15 WRX with that stereo and her phones. As soon as my number ports, I'll try mine with my 16 WRX. I have the premium version with the smaller non navigation stereo.

Yup, its the stock version. My S6 Edge before the v30 didn't have any issues. The calling thing is awful on the v30, it's unusable.

Same issue. My S6 never had an issue, however my new LG v30 sounds crystal clear when streaming audio but when I connect to a call, the call is distorted, broken, and static filled. I tried force stopping and clear data & caches of both bluetooth services, but nothing worked.
I also have a 2014 Subaru Outback with the stock radio.
My car is also a subaru (2012 Legacy). Issue is static in calls, however.
I have no problems with BT on my JBL headphones or my 2014 Ford Focus bluetooth but with my motorcycle bluetooth comm (Scala Freerider 1) I get playback of audio at like 75% speed with a lot of crackling and popping. No BT issues on the motorcycle comm with my Pixel C or S8.
I have the same issue. When I connect with my Bluetooth on my car the music plays but it randomly stops in the middle of the song, then starts again. It's like it loses the connection then gets it back right away. Doesn't seem to do it when I use the headphone jack.
In my case something different has happened.
The audio quality for connection inside the car gives a lot to be desired compared to the Galaxy S8 plus. I listen to the music as if it were with some bad quality or grit.
If the bluetooth has apt-x quality, it seems to me that my terminal does not hear how well this compression codec contributes, which theoretically transmits more audio data than bluetooth without apt-x.
Is there someone else who has the same thing?

Guys I'm new to the v30 I came from g4, my issue is that in my yaris 2014 I've connected the v30 but it doesn't recognize the phone, but it pairs as "unregistered" even I've tried to pair it with passcode but the phone just connects, and doesn't ask for any passcode after it connects I can play music but when I turned the car off and then on again v30 doesn't connect back, I have to unpair the car audio system to pair it again with the same problem of the unregistered device thing...
Edit:
Guys I just fix my problem downloading an app from the store that connects the Bluetooth to my car sistem, it recognizes it and connects automatically now, what I believe it is a problem with Bluetooth app from the phone itself
