Bluetooth dropouts when using stereo speakers

This is a long shot.
I have a pair of Bluetooth 4.1 Minirig speakers that can be set in stereo mode. However when in stereo mode one channel experiences dropouts. Running in mono mode is fine.
The issue is with the Nokia 7+'s Bluetooth transmission as when using other Bluetooth enabled devices to power the speakers the issue does not occur.
Anyone else had this issue when connecting stereo speakers or headphones and know of a solution?
I have checked: System > Developer Options > Bluetooth Audio Codecs and tried changing these setting but the changes did not "stick" and problem remained.
Maybe there is an alternative setting somewhere that can be tweaked.
Thanks in advance.

I'm also having this issue: whenever I'm connecting my N7+ onto the car's audio system via Bluetooth I have to change the codecs to the correct one every single time to make it properly work (have sound/audio at all). The settings also don't stick or are not being saved. Also looking for a solution for this, unless an update miraculously fixes it.

Same problem here when connected to my car by bluetooth. Occasionally there is a dropout. This does not happen when my friends connect with their phones (oneplus 5, samsung, allview. or my old lg g4).
Changing the bluetooth audio codecs does not work as it does not remain selected and it switches to default. This, as i understood, happens on android 8 and has been resolved in the Pie beta and should be ok in the final Pie release.

When I raised the issue with the superbly talented nokia tech support they either act surprised as if its an unique issue to you or send you a list of compatible bluetooth protocols. Are we expected to change our cars and speakers to make the phone work?

I had this issue after installing garmin connect. Theres a thread over in the garmin forums (forums.garmin.com/forum/into-sports/garmin-connect-mobile-application/garmin-connect-mobile-android/1375800-audio-streaming-issues) about it. Also on the nokia forums (community.phones.nokia.com/support/discussions/topics/7000022239/). Seems to affect some phones on 8.1
Anyway, I'm on Pie beta now and the problem has gone away.

Bluetooth issue

Dear all
First post so here goes. Had my 7 plus exactly a week.
Specs as follows:
Model TA 1055
Android 8.1
1st June 2018 Security patch
unrooted but themed with Substratum (Swift Black)
So my phone won't detect either my amazon bluetooth adapter plugged into my bedside radio or my creative bluetooth speakers. My lenovo p2 can find these without issue. Strangely it can connect to my PC's bluetooth which gives a passcode. I've cleared bluetooth cache and still not fixed. Anybody else had bluetooth issues?

TA-1046 here with June patch and I have bluetooth issues as well.
I was not able to connect my Gear S3 smartwatch to my phone, untill I decided to turn off BT and turn it back on again.
Suddenly it worked.
Then I was not able to update my S3 apps from the Samsung App Store, untill I stopped BT and turned it back on again.
It seems to me that there is a BT issues in the June patch.
How it was before, I don't know as I received this phone 2 days ago and it updated automatically to June update.

Sorry for adding more negativity to this forum than assistance.
I am also having similar problem with connecting to my LG sound bar. It picks it up when i search, saves it but does not connect.

BT issues
Well unfortunately I have to say same. BT even can't see any device during scanning. Other devices each between other works. Other devices also see N7+ and can pair with it. Seems like scanning doesn't work for me on N7+.
I tried reset networks, clear BT cache couple of times - didn't changed anything. Still wanna avoid factory reset.
No mods, no root.
I'm bit surprised (in the sad way) by this device :-/

In the meantime BT has worked quite well for a couple of days, untill today.....
I could connect to my Gear S3, but not much later I notice new notifications on my phone but no popup on my watch.
It turned out that BT was not connected anymore.
Manually connected and the same process happens again.
Untill I rebooted my phone. From then on, my watch stayed paired with the phone and didn't loose connection.

I lose the connection to my Gear S3 several times a day.

Try resetting your Gear S3 to factory defaults and remove BT settings on phone.
(also clear BT cache).
I had to set up my watch a couple of times.
Still it disconnects sometimes, but then a normal reboot of the phone helps to get the connection back.

Submitted this to another thread, but I'll copy paste it here.
I recently got Bluetooth headphones and found that playback easily got choppy if a part of my body was in between my headset and phone, or if the phone got locked. I did find a solution to this however, and not sure if it would work for everyone that has Bluetooth issues as well.
It seems as if Bluetooth has its own app on Android 8.1, and due to this, it's getting managed by Doze or the automatic app power saving that's on by default. I switched off battery management using the following steps:
1. Go to Settings
2. Apps & Notifications
3. Tap on the option that says "See all x apps"
4. Tap on the top right hand 3 dots.
5. Tap on "Show system"
6. Scroll down until you find "Bluetooth" and tap on it
7. Tap on Battery
8. Tap on Battery Optimisation
9. Press the blue dropdown that should say "Not optimised", and select "All apps"
10. Find Bluetooth again, tap on it.
11. Optimise should be ticked, tick "Don't Optimise" instead, then press Done.

My Nokia 7 plus cannot find other Bluetooth devices.
I cleared cache, went to battery optimisation settings, ticked on the Bluetooth icon and selected *"Don't optimise"* turned on my Bluetooth to search for other devices and still this same problem persists. Can't find other Bluetooth devices including phones, tablets and headsets. I'm really confused on why there should be such a problem. I don't want to Reset to Factory settings. But I'm not being left with any other choice. I'm so upset that I have to spend so much and yet other cheap phones can search for other devices so easily.. please I need a solution immediately

Audio via Bluetooth stuttering - unusable

Hi all,
The same headphones which used to work perfectly with my Huawei Honor 8 stutter upon Bluetooth music playback to the point of unusuable. It's the kind of stuttering like there's a poor connection/bandwidth issue between the phone and the headphones. It's similar to what happened on my Huawei Honor 8 when I was washing my car and ducked my head under the car
Tried multiple apps:
Google Play Music
Youtube
Youtube Music
Amazon Music
EDIT: ONLY my Philips SHB4405 headphones suffer! Tried different bluetooth devices to eliminate the headphones, same stutter.
Tried setting the special access to the battery use: "Settings", search for "Special access". Select "Ignore battery optimisation". Make sure "All apps" are shown. Select the app you want and set it to "Allow (May drain your battery more quickly)"
Tried setting Battery settings of the app to manage manually then Auto launch, Secondary Launch and Run in background all toggled on.
Any ideas please?

It is likely their hyper-aggressive battery management software, which there seems to be no way to remove.
You may try to go to development mode menu and play around with the BT audio bit rates and codexs. Or, just take it back to the shop and exchange it for a new one.

try turn off WiFi ! - > WiFi + Bluetooth = stuttering

I'm using my phone with two BT device, one is a Jabra device I have in my car, the other one is the Backbeat fit from Plantronics. Honestly say BT communication works very well. EMUI 8.1.0.161 (C432)
Any update available for download?

funnily enough I did have an update apply yesterday but it didn't fix this behaviour. EMUI 8.1.0.159 (C782)
I have an update to my OP though. The bluetooth music streaming actually works perfectly on every bluetooth audio device I have (Radio, AV receiver, 2 x car stereos, bluetooth speaker, another set of bluetooth headphones) so I can only assume that the Huawei P20 Pro is incompatible with the Philips SHB4405 headphones! sounds bizarre to say it but that's my experience!

Bluetooth codec fix
I fixed this on my Honor 8x by changing the bluetooth codec used in the developer settings.
1. Enable developer settings
2. Change the "Bluetooth audio codec" setting value from "aptX" to "SBC"

Hi mate, check the supported codecs on your headsets. Enable developer options in Settings and force SBC codec.

Has the latest 9.0 solved your Bluetooth problem?

I have the same issue with Bose and Jabra headsets... Cheap chinese BT headsets Line taotronic seems to works fine.. I have given up trying to figure out the cause... Thing is I love the p20 Pro but this BT problem is really annoying!

Hi Guys,
I have a P20 and I love it, but had the BT audio stuttering problem in my car for a while - the radio is fine, my gf's Samsung can stream to it no problem.
9.0 didn't help, the problem persisted until... I changed the display sleep time to 10 minutes and forgot about it.
So after some testing I can 100% confirm that the stuttering happends only when the screen is off.
When I drive with the screen on, the BT music streaming works great. When I turn off the display - within minutes the stuttering starts. Turn on screen again - no stuttering.
Test it.

Happens on my Mate 10 only when screen is off. I already removed PowerGenius and had set battery optimization off to my music app. This is so annoyingly frustrating. Any solution yet?

I think I have the same or a similar issue using Beoplay H9. Changing codec to manual SBC or AAC does not work, but SBC is noticably better.
Closing all open apps or restarting bluetooth often works, but restarting the phone completely alleviates the problem. After an hour or two the problem appears again.

Can you check if the headphones are paired to anything else in the vicinity? Like a tablet or other phone? May be the problem..
Also the codecs in use make a difference too, can be altered in Dev options.
I had problems with calls with a very expensive pair of plantronics on my phone, the v6200's £275 when they were released lol.
Base didn't make a difference either Oreo all the way up to 9.1, in fact it was better on Oreo.
Doesn't affect everyone in the same way.

Paired to stuff yes but I can take them out of the question by wandering away from any of the devices for a 1-2 mile walk

Still experiencing this same problem on EMUI 9.1, even after disabling battery optimization in all music apps.

This worked for me - turn off 'Always on Display'
I was getting brief but regular strutters with my bluetooth headphones (Marley Positive Vibrations 2) but only when the p20 pro was put in my jeans pocket, so walking the dog while listening to Spotify was a pretty glitchy affair. At first I assumed being inside the pocket was degrading the bluetooth signal strength but I recently noticed that whenever the phone sensed it was inside my pocket (or in a pitch black room) it was turning off 'Always on Display' to save battery, so wondered if this was affecting the bluetooth audio connection (especially as people already suggested it was related to either display settings or battery saving options).
I disabled 'Always on Display' and this stuttering problem has been completely resolved for me (EMUI 9.1).

@theToots
Where to find the option 'Always on Display'
edit:
Found

I have this same Issue using a P20 Pro and Sennheiser HD 4.50 btnc.
This annoying audio stuttering started happening only after a software update (EMUI 9.1.0.361).
A fix that works for me is to turn my location off.

XZ1C Bluetooth Dropping.

Bluetooth is dropping within a few minutes every time with this phone which is running the most up-to-date software. I feel like I have tried everything under the sun to fix this including, but not limited to:
Network Reset
Software Repair
Developer Mode Settings
Has ANYONE experienced or managed to fix this issue for themselves?

When I listen to Spotify via bluettoh headphones, sometimes the sounds starts cracking a lot (due to bluetooth interfierence). This happens when wifi is connected to 2.5ghz router + there is a lot of data being downloaded. Most cases restart helps, as after restart wifi data download decreases a lot. If that does not help (may be just few times restart did not help), than I switch off wifi and use celular data. After that bluetooth headphones work well.
PS I am on latest Oreo. Did not update to Pie as call recording does not work anymore without root.

Thanks for your reply Martynas. I have indeed tried using BT with wifi disabled, but it is the same result.
I would actually really like to try downgrading to Oreo to see if that fixes things, but I am new to Android and so I don't exactly know what I am looking for in my hunt for a US image that will work with T Mobile.
Any advice? Thanks for your time.

One more option would be to try different bluettoth settings under "developer" options. Try using different protocols. Mine all are on auto, but try to use manual settings... lower versions, lower bit rate and hz.
As to downgrade to oreo, there was somebody in the forum who has done it and was thinking to make step by step manual... check with him for help.
PS one more possibility - the headphones are broke or simply not very compatible (if it is just earphones you have problems with)...

Takes 2 devices to make a bluetooth connection. Could be your other device. This phone is running bluetooth 5 which is very good. For HD audio you will need very close or line of sight to get constant audio.

I have tried all of the developer settings to no avail. The headphones are not broken and indeed are compatible. The XZ1C just simply doesn't hold a connection with any BT audio device whatsoever.

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.

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.
