4.3 Bluetooth Issues

Just wondering whether there is any fix for the bluetooth issue on 4.3 roms. I can connect my phone to car without any issues, but cant syn contacts or answer/reject calls via steering wheel. If not, is it possible perhaps to copy bluetooth related files over from 4.2?

Quite the same problem here. I can pair the XZ with my Car's device (ego flash), but I can't synch the phonebook.
I already deleted the Bluetooth setting on both devices, nothing helps
if somebody has a solution??

sorry for my bad english...

I'm having exactly the same problems.
And it seems as if every android update on my xperia z fixes some bluetooth bugs and brings up some new ones. After each update, my phone behaves differently in my car.

I had the exact same issue, (to give a little more detail) it causes you to either drop wifi connection when on bluetooth or vice versa and i had just bought a sony smart watch that ran off of bluetooth.I never found a fix from sony. What i did do to fix it was flash myself the latest eXistenZ rom, it worked perfectly and both my smartwatch and wifi could work at the same time

Same song different dance
My issues with 4.3 update are related to the poor performance of the bluetooth driver on audio connect.
I have downgraded to 4.2 because i use bluetooth headphones and i have 2 bluetooth speakers, that with the 4.3 are almost useless because:
Low volume output over bluetooth, quality of the audio is a bit down, and most important for a heavy sleeper, the bluetooth speakers are working only with music/video soundtracks, they are not ringing anymore on phone calls, alarms, notifications.
Please, anyone, put the 4.2 bluetooth driver somewhere, flashable or i dont know, i tried everything, but i guess the best option is to install the 4.2 bluetooth driver on 4.3. Is it possible?

Now I found an workaround for me. I deleted all the photos inside the contacts ( about 8 or 9 contacts of 331 had a photo inside). Phone-Book sync and sending contacts separately is working now. Not perfect, but OK for the moment.
Could this be a problem with Android 4.3 ? I never had that before with my Defy, Razr i, Wiko Darkmoon or Alcatel OT6040D.

Bluetooth connection to in car entertainment (phone book issue).

Hi XDA'ers.
I've got an Vauxhall (Opel) Astra with in car entertainment / gps / handsfree.
The system allows calls to be taken via a button on the steering wheel.
There's also an option to import address book details into the system, it just doesn't want to work with my Z (latest stock rom, unrooted).
My wife's iPhone (grrrr) paired fine & all contacts present.
There's profiles for 6 device connections. My Z pairs ok but the unit won't bring up any address book & I still can't answer / hang up hands free, I have to do it on the Z.
Is there a setting on the Z I need to enable that I've missed? The only bluetooth options there are connect / disable & use for call audio.
I've looked over all the settings on the head unit & exhausted my options there.
Thanks in advance guys.
Dazza.

That will Not Work Since android 4.3. I have to use rsap to connect to my phone and the phone needs to be rooted for that

Bluetooth Bugs - OOS Open Beta 8

Starting this thread to see how prevalent this bug is, and if it's something fixable or just a bug that will need to be fixed in the next update. It appears to be affective at least a few other users as well (https://www.reddit.com/r/oneplus/comments/5g89wa/oos_beta_8_bluetooth_issue/)
Much like in the linked thread, I have been having issues with BT connectivity with my car, such that BT audio plays but voice search feedback on android auto doesn't play. also noticed that BT subsettings are all unchecked for all paired devices (phone audio/media audio) despite that both work. Anyone else seeing other bluetooth issues on this build?

Yeah, I can no longer even pair my phone to my car (Mitsubishi). It just won't work no matter what I do.
It worked just fine before.

Tested mine tonight, device paired and everything was working well.

Had no problems using various bluetooth devices like speaker, gamepad and BMW car unit

Only issue I am having is with the mi band 2. Notoriously awkward when it comes to BT at the best of times.
Wife's Audi took two attempts my MB worked without issue.
Bose stuff working perfectly.

Got the same issue, pairing well but reading sms function doesn't work anymore even on stable version!

Having problems with vivoactive hr and the Garmin Connect app. Not getting notifications, and have to toggle Bluetooth off and on to sync.

Sometimes having trouble connecting via BT to my JBL sound bar. One time it doesn't connect at all, sometimes my phone connects, but no sound. Now testing again, all works fine. Using Deezer as I type.

P10 and Android Auto

Hello,
Today I installed the SONY XAV-AX100. Super. Everything works quite smoothly. I just have a problem with calling through android car. If someone calls me or call me and I connected via android car, so the call does not appear on the radio display only phone which is useless.
When I tested the Nexus 4 with Android CyanogenMod v6, it works well.
Some idea?

Firstly double check your bluetooth settings for that device and make sure all the sliders related to phone calls and Bluetooth audio are enabled, if that doesn't work - try a variation of making your head unit connect to the device and vice versa.
I have a 2014 passat and the Bluetooth works perfectly when connected, first connection on car start is a bit pissy because my smartwatch initially demands all Bluetooth, manually connecting to the VW Phone in Bluetooth just reconnects both devices and it works fine for calling, music and voice control.
If these tips don't work, It might sadly be a lack of support within the head unit itself (some are very picky)

@stevob21
You don't have AA and don't understand the problem, so why did you respond? It's not BT related issue.
@matata86
I have the same problem. AA has all needed permissions, but calls still not show on the unit. Interesting is that with my previous phone, P9 - it was working as long phone has Android 6.0. After update to 7.0 - it has stopped working. So it has to be related with Huawei's 7.0 phone manager. Someone with root access should try to freeze phone manager and check it...

Yeah apologies, I must have got this mixed with another thread I was looking at when writing this related to BT issues when connecting where phone calls/address books aren't operable though they work fine after manually initiating the connection.

Same problem here. I can make calls with "ok google, call John Smith" but the notification doesn't show in order for me to end the call. I can end the call from the phone but usually rely on the other party to end the call from their phone.
Text messaging has similar behavior. I can send text messages from AA using voice commands but cannot receive them on screen nor are they read back to me. Again, they do show up on the phone.
All notifications are allowed for the phone and messaging apps. I've also set the battery manager to NOT turn off those apps to save power during screen off. I've tried other phone apps, though I didn't think this should matter but why not try
The deck is a JVC KW-V930BW and the phone is a P10 plus. All other Android Auto features seem to function correctly. I read in a forum for some other phone brand that exhibits the same behavior that it is due to some security feature in that phone and cannot be changed. I wonder if that is the case with the P10 plus?
Anyone else run into this or have a fix? Thanks all!
PS: not interested in rooting.

follow-up
From a thread in another forum, this appears to be an android auto/huawei compatibility issue that they're working on. A recent update seems to have fixed an sms issue so now text messages are read back to me. Regarding the phone notifications, I've mounted the phone using a magnetic vent mount close the steering wheel so I can end calls easily from the phone itself. I'm going to call that "good enough"

It seems to working now with B171, at least in my A6 from 2015 with the latest MMI-Update.

All of a sudden mine is working too, though still on B170. The only thing that changed that I can recall is I updated Google Messages and was prompted whether I wanted to make it my default messaging app to which I agreed.

In Car Bluetooth Handsfree Issue (No Sound, No Microphone)

Symptoms:
Phone connects to the car just fine. Streaming audio from Spotify works great, with all track metadata showing on the car's screen. However, phone calls will not work. I can place the call using the car's built in controls and the phone responds as expected - the target caller's phone rings. But.....I can't hear anything through the car nor can they hear me when they answer. I have to always re-route the call to the phones speaker which is really frustrating. Same issue if they call me - music mutes ready for the incoming call, I answer, silence..... (until i force the call through the loudspeaker)
Car's Tested (all the same):
Hyundai i30
Audi A6
Land Rover Discovery
ROMS Tested (Cache all wiped between installs):
OOS Nougat (Stock, Locked Bootloader)
LineageOS 14.1
OOS Oero 5.0 (Relocked Bootloader)
OOS Oreo 5.0.1 (Locked Bootloader) - current
Is there a ROM or Kernel that would fix my problem? This used to work when the phone was new, but didn't fancy rolling back to the original firmware if possible - I'm become accustomed to the new features in Oreo

I've had the issue where the music would not play, but phone calls were working correctly. In my case I went to the Device Bluetooth Settings in my car and had to enable the ability for Music Playback. Also had the option to enable/disable calls and Pandora.

Is there a solution by now? I have exact the same issue, tried several Roms and different handsfree. Switched several settings in bluetooth options. A mounth ago I opened a ticket on oneplus support but no solution till now.
