[Q] Headphones not working...

All was working fine this morning then in the afternoon plugged in my headphones (I have the Sony Noise Cancelling headphones made to work with the Z3) and they were not recognized.
Got home, plugged in another pair and not working.
Tried the earbuds that came with the phone and also not working.
Did some research, cleared cache and data of Smart Connect app but no change.
Did a factory reset, still not working.
Updated Smart Connect and got headphone sound but it was VERY quiet. The phone was picking up the headphones as a headset.
Finally, downloaded the third part app Soundabout and I can connect my regular (non-noise cancelling) headphones if I let that program override the phone settings.
So, seems this is not a hardware issue but a software issue? Can't seem to find any info about this anywhere else besides a couple of forums on the sonymobile site, but doesn't offer a fix that is working for me.
Advice or tips?

got worse...
And now the headphones are VERY quiet even when using the Soundabout app...

PIE Update - Car Bluetooth Issue

Received PIE OTA today. Everything seemed great until I got in the car to drove home from work. Phone connects to Bluetooth fine and stayed connected until I tried making a call. When I dialed a contact it started ringing properly over the car speakers then dropped and the status stopped showing on the car display. Phone still said it was connected to BT and phone audio routing through the Handsfreelink. I couldn't hear anything. Switching the call audio to Phone I was able to hear the person through the phone handset.
I've tried repairing to the car and restarting phone. I did not try calling through Android Auto I interface on the car, but will try that tomorrow.
Looking for similar issues I saw some hit for the Pixel devices, but it was on older beta builds of PIE.
Anyone else have this issue?

I don't have your exact issue, but my Bluetooth keeps disconnecting on my car. It worked fine on 8.1.

I also have the problem through the Android Auto app. I cleared cache from recovery and still have a problem. This makes Android 9 unusable for me...

Are you using a Galaxy watch? I used to have the same problem until I reset my watch then everything worked fine.
I would recommend you find out what's disconnecting the bluetooth through bluetooth > Advanced > Bluetooth control history and see if there are any apps turning off the bluetooth. Galaxy Wearable was constantly disconnecting my bluetooth when it was disconnected to my car's bluetooh and that's why I reset it.
I hope that helps.

I recommend you delete your phone 's profile from your car and reestablish it all over again after your reset your phone's bluetooth as well through settings > general management > reset > reset network settings. Bear in mind that this will erase all your bluetooth connections as well as wifi data.
Good luck.

I have already tried deleting my profile in car and clearing Bluetooth and network connections. I dont have a smart watch. The only thing left is a factory reset. But I've been reading the same problem has been reported on Pixel devices on Android Pie. I didnt see a fix though.

I have issues while playing music on Spotify and black player ex via Bluetooth on my pioneer deck in my car. The music will stop playing for like a second or two then resume. Reverting to 8.1 fixed it. I've tried a clean wipe as well.

Reverting will only fix it until the OTA installs it again though.

Wow. Thats definitely a deal breaker for me..Kind of glad Sprint hasnt received it yet! hope they fix it as I know how annoying that is.

I have the same issue, Phone will connect fine initially but after like 5 minutes of playing music or calling Car will lose connection all together to BT in Phone (phone says it still connected for a couple of secs then drops as well) If I leave alone BT will connect again after a minute or so then disconnect again in a couple of minutes
I'm using Android Auto on my phone (My car does not have AAuto so use the phone as a display) so everytime BT connects disconnects AA launches
Tried resetting BT cache and data and repairing but everytime same thing.

Are you using Android Auto on the phone by any chance?
What brand Car do you have?
I tested today after some BT resets and in the morning everything stayed connected so I thought it was fixed but in the drive home it disconnected 3 times while in a call !

I can confirm that this is happening specifically for me as well. Long time lurker/reader.
I'm confident I've isolated the issue to the Pie update. My Google search bringing me back 180° to here supports that.
I have that sinking feeling that this is gonna be an ongoing bugaboo. Let's hope I'm wrong!
I'm not an Android Auto user. The accompanied "drop signal" notification from my Galaxy Watch losing BT signal to phone to every few minutes is slowly eroding my sanity. Most recently on official AT&T CSAA clean wipe.
Cheers!

What's the current version of Pie on our Note 9 at the moment? From the looks of all these posts describing issues, I may have to permanently remain on Oreo for the entire life of this phone.

Hi, Annon here. Here's a real quirk... After receiving the update on my phone, I was happily driving home with music streaming through spotify via bluetooth and my husband decides to call me. The phone rings, I try to answer from the steering wheel and instead of answering the phone, it looks like it's connected the the car is still ringing the phone at me while not connecting to any voice. On my husband's end, he gets this really loud and annoying screeching sound so obviously he hangs up. But it doesn't stop there. Even though the call is disconnected (not that it ever stopped ringing on my end or connected), the phone continues to ring through my car UNTIL I GET HOME AND TURN OFF MY VEHICLE. Even after I turn off blue tooth and the radio console. It was the cherry on top of my crap day.

PIE in the face
I have exactly the same problem with a note9 connecting to a Discovery Sport. The phone connects for a short while then drops completely, then reconnects automatically and cycles like this for 3 or so times then seems to stabilise.
If I am on a call its a total nightmare, thinking of trying to revert to Oreo.

Anybody have a fix yet besides revert to oreo firmware?

Note 9 At&T on latest pie. Can confirm Bluetooth disappears from memory. Happens to car, headset, watch and have to re-pair over and over. Pretty frustrating. Was working perfectly prior to pie.

I chatted with Samsung+ after I told them I already FDR'd my phone and everything else they asked about they recommended I get in contact with the warranty Dept so I can get another phone that will have the same issue once it updates to Pie

same issue here . Before describing issue please e-mail me if anyone has a fix ([email protected]) .
I have Galaxy Watch and a Honda Accord 2017. Everything went fine until upgrading to Pie. Now when phone is connected to the car system it rings but cant answer the call. Not on my steering wheel nor on my touch display. Furthermore if I try calling back It rings until person answers call and then it totally drops the call from my car system. Very annoying . If anyone comes with an answer to that please e-mail me the solution

Flashed back to 8.1 and no issues, I removed system permissions for the software update app and so far it hasn't automatically updated, I just get the persistent notification.

Same here - I just migrated from my oneplus 3t to the Note 9. And as a constant User of Android Auto, this is really a big big issue for me. Any hints besides Re-Odin?

Bluetooth disconnecting in car but not headphone

Bluetooth is working correctly on my headphones, but not on two different cars that I've tried. I get a message on the bottom of the screen that says the car is attempting to access messages, yes / no, but before I could answer it I get 'com.Android.Bluetooth keeps stopping' and my phone is disconnected. Do I just have a bad Bluetooth radio and my phone, or is there some other way I can fix it?

Are you rooted? Have you tried using titanium backup or other app to clear cache of Bluetooth, then try again?
What are you running, WW or CN?
Actually, can you not just go to apps, show system apps then clear cache from there...

Not rooted. US device, stock WW rom PKQ1.190414.001.WW_Phone.16.0631.1908.12
In apps > show system > Bluetooth I can do Force Stop, but not Disable. I cleared cache and data. Hopefully that'll help.
Any ideas on other things I can try if that doesn't fix it? I'm able to listen to bluetooth headphones for hours with no issues, so I don't think it's a hardware problem.

Can you allow access if you went into the Bluetooth settings on your phone for your car?

I used mine for 2 days with a 2014 Toyota Camry, playing my music for about 2 hours of driving with no issues.

its not the bluetooth
seems like the phone triggered the airplane mode on and off randomly, all connections in the phone disconnects randomly.. check your phone, when bluetooth disconnects check the signal bar of your phone its also disconnected, i also have this problem and its not only the bluetooth disconnects randomly, all connections like wifi, and Mobile Network

Bluetooth earbuds can't connect.

Hello, after 2 and a half years using the phone and not having big issues, just the known (red tint screen etc) and saying that the phone itself still stands good, i now have a problem. I just purchased the Creative outlier air v2 earbuds and i simply can't connect them to Nokia 8. Phone hasn't been tweaked , is stock Android 9 with the last October update. The phone discovers them i pair them, i hear the "pair successful" from the earbuds but they don't connect , instantly they appear in "Saved Earbuds" section in Bluetooth settings and the earbuds flash as they supposed to when they are disconnected from a device.
I tried pretty much everything i can find, Bluetooth on-off, developer options on-off restart, clear bluetooth app cache, clear apps settings even clear WIFI/Bluetooh cache (bye -bye wifi ssids) tried to changed the avrcp bluetooth versions to 1.4-1.6, select aptX codec etc but nothing changed. The disable bluetooth a2dp hardware offload is grayed out so i couldn't changed that, but don't know if it will make any difference.
So is there a thing i can do to make them work, tweak/re install firmware or version of bluetooth ? Or i just hit a situation that the two devices just don't go along.
Just for the record, the earbuds pair and work fine in my laptop and even in 2 Xiaomi redmi 5 i tried to.

IDK if it helps, but Creative recommends to use the SXFI app (https://play.google.com/store/apps/details?id=com.creative.apps.superxfiplayer&hl).
Install this app
Create your profile
Connect the earbuds to your device
Have you tried it already?

Yeah i tried that, creative suggested some methods mentioned it this site, for different Nokia models, but it was basically what i've done already(clear apps, cache, reset phone) I've given up, the only solution is just use different phone...

Question Bluetooth disconnecting frequently

Got my 21 ultra four days ago. Came from a Note 9. I have a Motorola headset on most of the day. Never had an issue with a disconnect with my Note 9.
About maybe every 1-2 hours I get a notification through my headset that the Bluetooth has disconnected and reconnects fairly quick after. That happens when I'm not on a call.
When I'm on a call it doesn't alert me but I can tell I lose the person I am talking with for about 5-10 seconds.
I have done all the clearing cache, resetting network, etc. Was hoping someone might be able to give me any tips.

Have you tried with another Bluetooth headset? It will help diagnose whether the issue is with your phone or the headset.
I have been using my S21 Ultra with the following bluetooth devices and not lost connection unintentionally even once since I've owned the device (across all software updates so far)
1. Galaxy Buds Live (use them for hands free calls all day)
2. Anker Soundcore 2 BT Stereo speakers (for music)
3. Mi Outdoor BT Speaker (podcasts at night before sleep)
4. OnePlus Wireless Z BT neckband earbuds (for running and other exercise)
5. QCY Airdots TWS earpbuds (general purpose audio)
6. House of Marley BT speakers (Hi-Fi audio streaming)
Please test the connection with another BT headset and check if the problem persists.

Yes I have the Motorola Boom 2 plus which I used with the Note 9. I have three of them and tested them all.

Disable all power management... destroyer of worlds
Developer options>standby apps, all buckets should show as active otherwise power management is active.
Make "save battery" isn't enabled for Wearables or other needed dependencies.

Also I don't see Save Battery in developer options.

That won't do it. It's still active; those buckets represent the ones you can alter and even those may not "take".
You toggled on adaptive battery etc in Device Care*. The only thing that should be enabled is fast charging.
The Power Mode should be Optimized or higher.
Clear the system cache as well.
Hopefully this will cure the cutouts... it worked for me and stopped a lot of other erratic behaviors. Battery Optimization etc was always a dog. Android does fine by itself. However some apps like Brave need to be closed out or they run in the background wasting power.
If you're battery life is bad or gets worse let me know.
*I'm running Pie on a 10+ but they should be similar.

Sometimes apps will interfere with Bluetooth operation and clearing the cache can solve the problem. For Android phones, go to Settings > System > Advanced> Reset Options > Reset Wi-fi, Mobile and Bluetooth

After all power management is disabled clearing the system cache on the boot menu advisable and maybe a network reset.

Edit: Looks like more than one user is having this issue. So could be an issue with the phone itself instead of the headset. I haven't had a similar experience so I don' think I'll be able to add anything of value here. Hence removed my previous suggestions.

It happens to me very often... I use Buds+ and Buds pro. I am connect over bluetooth to my laptop, galaxy watch 3 and buds. During phone call it disconnect and I must connect on py phone again. Mostly I see it just change output to phone. And I have to change phone call output to buds
It is very frustrating. Cos It happens during call. And I have to manualy change to buds during call... Do I have any weird option enabled so buds diconect durring call?

Maybe because of so many bt devices, try using one or two at first.
Make sure Wearables is up to date. Samsung sometimes pusher out updates frequently, it may fix it. Lol, I waited almost a year for the Buds÷ sound fix
Network reset. Then add only what is needed.
Clear system cache.
Hard reboot.
