Bluetooth Headset Not Working

Hi Team,
I installed the ROM update to B853 on my P7 and my Jabra stealth stopped working. It is connecting OK but I cannot hear the caller. I have tested the device with other phones and it is working OK. The Jabra stealth was working when I was on B830. Has anyone experienced this. How can I resolve the issue?
Thanks,
Kabuti

I Tested another Bluetooth headset and the result is the same. The caller can hear me but I cannot hear the caller. This is pointing to the B853 update. Assistenace will be appreciated.
Thanks,

I've the same problem with the car's bluetooth.

I have same problem past year from the beginning I have P7. Actually this is first time I came across same problem through internet.
Not exactly sure what version was phone originally since that still same with B609 and now B852. I was hoping to improve through updates but with no change. Since this thread I was getting to conclude that this is mechanical problem of my device (girlfriend has P7 from another distribution with no problem).
Testing let me know that it is only related to hearing caller. Streaming audio and others sound related bluetooth services works fine. Met this with various headsets headphones and cars. Still same at one time of ten works fine than nothing with no clue on repetition or pattern.
If we can gather more details may be this worth while to post to Huawei

Any solutions for this problem until now?
I have the same bluetooth issue on Huawei P7 (B852). The issue first appeared with upgrading to Lollipop. Before everything was fine.
Now - as CADAC described above - bluetooth connection seems fine: audio streaming, sync with fitness tracker - everything is ok.
But regarding phone calls I can't here the caller, I even can't here it ringing if I call somebody.
After factory reset / wipe data it first seemed ok, but after a second phone call the problem was there again. I've tested on my car (Mercedes A-Class, Audio 20 System of September 2015) and also with a regular bluetooth headset.
Yesterday I've installed the app "Bluetooth Auto Connect" --> https://play.google.com/store/apps/details?id=org.myklos.btautoconnect&hl=de
Just a little configuration inside the app.
It is currently working!!!! Until now ... Let's see for how long.
Anyone else with this bluetooth audio issue who can share experiences???
UPDATE: The no-audio-issue is back again. Bluetooth Auto Connect doesn't resolve the issue!

Google Now is not the problem as I do not have it installed and still cannot call or answer hands free on the P7. Blue Tooth Auto Connect doesn't solve it either.

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.

P20 Pro - Microphone issues

Hello,
I got myself a Huawei P20 Pro and am fairly satisfied with it atm. But there is one issue I have now and that is that apps like Line, Teamspeak 3 and even the phone app is using the wrong microphone when using a Bluetooth headset or even an USB C -> 3,5 mm headset.
One thing that I do remember now that I am writing this, is that I have Boldbeast Recorder installed, which is a call recording app. But I never had these issues with my Samsung S7 Edge.
Anyone else having similar issues?
Update;
I made a call earlier today and had these issues, but using the handset itself. But after a while even calling seems to not be working.
I did a quick reboot and now, huzzaa, everything works again...

I have Huawei P20 Pro and I use Boldbeast call recorder. It works fine with the handset as well as work Bluetooth

Same problems and more....

I have the same problems with my P20 Pro! I can't make calls after a while with apps like messenger och WhatsApp, and after a while even audio when recording video I gone! A restart works for a while but then back to same behavior! This is really bad if they want to compete on the high end market... Hoping for a system update that fixes this ASAP!

Hmm, I think it happens for me whenever I use my Bluetooth headset (Jabra EVOLVE 65 MS). After I stop using it and go back to my USB-C -> 3,5mm headset it has that weird bug again.

For me it all starts working after a reboot :s
I got 3 days more to decide whether to keep it or not :s

So, I ended up returning my phone and got myself a Samnsung S9+ DS....
I am sorry!

I said earlier I don't have problem, but I do have problems with phone calls. The other party cannot hear me well. Maybe it is something to do with using Boldbeast. It records well, but maybe it interferes with phone calls. Can someone confirm this?

I'm regularly having the same issue.. Occasionally the other person at the start of a call can't hear me..
I have only yet encountered the issue with actual phone calls not whatsapp voice calls etc..
So I'm wondering if it's perhaps a VoLTE bug?
Or the only other thing I can think of is that perhaps the USB-C to 3.5mm headphone adapter plays around with the audio pipeline and doesn't reset.. Just speculation

Microphone error
Same to me here... Is there any solution? My friend can't hear me at all on the phone call... But when I playing PUBG with microphone enable they said my voice just like cartoon....

Private space is the key. I guess
Switching to private space.. ans switching back.. make u lose mic in calls.
I am sure of that.

There seems to be a few causes
Potentially:
1/ going into private space
2/ after using usb-c headphone adapter
3/ after using Bluetooth Audio
Still wondering if it's a VoLTE thing or if it also happens with whatsapp during a microphone. If it's only effecting phone calls and not apps that use the microphone that would point to volte or some other part of the call pipeline rather than the general audio pipeline
The only solution I have is to restart the phone.. That works
..

It seems like a firmware issue connected to the mic. Hope this gets resolved soon.

Same issue here.
I tried turning off VoLTE and WIFI calling. No luck.
This is really giving me a hard time. I can't make calls anymore.
People just don't hear me.

Do you guys have the dual SIM version? How many cards installed?
I removed the Sim in slot 1 yesterday and when I slid the tray back in the phone showed an update for the provider settings (and provider apps etc.)
I run the update and restarted the phone. Some provider apps were installed with the update.
--> first call went without problems.
--> maybe 2 SIM cards interfere?
--> maybe the provider update needed to be forced (by removing one of the SIM cards)
--> maybe it was just the reboot.
I'll keep you posted.

4 calls since last post (no restart since).
--> procedure might have done the trick.

Has anyone managed to fix the problem with update?

No more problems?

im having the same problem, i tried restarting and formating the mobile.
Fixes it temporary only.

Do you have two sims installed or just one? Try taking one out if you have two (see above) to trigger a provider update.

Ok, I have two sims in the phone. But now I deny Google permission for the microphone (I don't use "ok Google" to wake up), and never happens again, microphone works fine all the time.

Bluetooth is not working properly!

I connected my Huawei bluetooth headphone with my P20 pro and than tried to listen music but it interupts every 5 secs! I use the same headphone with my laptop and other mobile and it works perfectly! What could be the problem of the P20 pro? Not transmiting bluetooth signal properly to the headphone or what?

Google navigation too...... Stop the voice in the middle of the text!

I use and have tested my P20 Pro with tons of Bluetooth devices, headphones, speakers,my car and all work fine. I’m using AirPods as I reply to this , no issues. Check out my audio review of the P20 Pro on my website or YouTube channel.

Tried with my pioneer 80prs, with p88rs2, some ford sync 3 models, 2 wireless speaker (anker soundcore 2 and JBL), also with 2 echoes from amazon.
All work fine, no problems with bluetooth connection or disconnects.

I having the same region and model as you. I never try connecting to car so I don't know but other than that everything working fine for me.

Not sure if it's related but I had a problem with several Bluetooth devices (Car, Garmin Watch) suffering connection issues and it was down to a battery saving setting.

Yeah my JBL headset skips all the time on my p20 pro. It's unusable. Really annoying. Can't really find a fix either.

Bluetooth issues Zui 11

Dear XDA-devs,
I am having issues with the stock version of Zui 11 (made possible by SrCDA)
When i connect Bluetooth headphones or in-ears, audio does not come through, no sound at all (i tried several all have the same issue). YouTube also keeps stuttering after connecting headphones.
Can anybody help?
PS the phone is not rooted
Kind regards

Same thing happen to me, no solution yet?

Which issue?

Good point, i forgot to explain the issue
I eventually received notifications for Whatsapp and Gmail, but the phone would not vibrate or ring. I checked the notification settings for the apps and i checked the settings for ZUI security and the vibration settings but nothing worked. The phone would not vibrate or ring when i received an app or email.

I use Sony WH1000XM3, for bluetooth problem I finally solve it by entering developer option and change the bletooth codec to Qualcomm aptX HD

Bluetooth issue is fix on latest ZUI 11 update to Android 10
