Nexus One Bluetooth issues (short version: it sucks)

Moved from a MT3G to the Nexus One, and I've been very disappointed by the Bluetooth.
The phone pairs fine with my Bluetooth devices, but it rarely transfers the audio. I've tested it on several devices:
Chrysler MyGig: pairs, but doesn't transfer audio. Carkit DOES show incoming and outgoing calls, but audio stays on the phone. Pressing "Bluetooth" in call doesn't do anything.
Garmin Nuvi 855T - pairs and calls work, but it regularly pops up with "phone connection error"
Spracht Bluetooth carkit - pairs, but same audio transfer issues as on the MyGig unit.
These three products worked perfectly with the MT3G, so I'm curious what Google broke and whether any of the other non-stock roms out there can make Bluetooth work correctly.

having issues myself with streaming A2DP in a 2010 VW. Phone works great but music clips almost like it's buffering. Issue doesn't exist with other phones.

My issue with bluetooth is I cant send files to my laptop anything works fine...

Don't know about your issue, but my N1 hasn't had any major BT problems. Occasionally it drops out while running with my Plantronics with A2DP, but that happened with my G1 too. File transfers are no problem for me either, and I never get disconnect problems. Stock rom was fine too with BT before I installed CM5. Maybe you have some app that's interfering with it? Try killing everything.

I have an aftermarket parrot bluetooth car kit and its worked perfectly with every phone ive ever had: sidekick 3, tmobile dash, bb curve, g1, bb 8900, mytouch. and now with the nexus it says it pairs but wont connect. so its completely useless. and i live in california so i have to have handsfree. bummer.

What annoys me most is a) how this wasn't picked up during testing by Google and b) how they managed to break something that worked perfectly on the G1 and MT3G.
It has been submitted as a bug in Google Code, but that doesn't mean they'll fix it. Sad that I have to use an iPhone just to make calls in my car when I paid $563 for the N1

my jawbone prime works great..
sometimes i have to send a file twice to my mac, but it does send, and i can send from mac back to the phone

Really? My first, and ongoing, impression of the N1's blue tooth is that it's really slick.
It pairs with my in dash NAV on my '09 Jetta TDI before I pull out of the driveway, every time. Phone calls always work and the A2DP streaming is flawless, this is the first device I've seen it actually work and play well with -- consistently .
The sound quality is BETTER than my iphone through the apple A/V cable; with the iphone I had to put an audio filter inline behind the dash to suppress engine noise caused by a ground loop. I'm considering removing it now since blue tooth A2DP streaming would obviously be immune to this problem.
I couldn't be happier, personally. I can control playlists from the stereo head unit or the steering wheel while the N1 is in my pocket. It's been very reliable and has performed beyond my expectations... not to mention the "wow factor" when somebody realizes where the tunes in the car are coming from.
For me, the blue tooth performance has been an unexpected bonus... It wasn't a consideration when purchasing the phone but now I feel it's become a "must have" feature.

- Honda Car Kit
- Philips SHB7100
- Gear4 BlackBox
- two Desktop Docks
are working fine.
"Audio Link" sometimes has "clipping".

Pairs fine with my Garmin Nuvi 265WT, however ALWAYS drops a call around the 5 min mark. My G1 did the same thing with my Garmin Nuvi 680.

My N1 won't work with my 08 Nissan Xterra. Pairs just fine but won't transfer audio. This worked fine with my Samsung Blast, G1 and Cliq.
There is a thread about this on the google nexus one help forum but unfortunately I'm not allowed to post external links. I'd recommend voicing your problem over there to let google know this is a widespread issue.

I have problems with my BMW Bluetooth car kit. It connects, phonebook transfers, try and make a phone call and I get no sound. Receivers phone rings but no sound in the car. Once the phone call is cut the Bluetooth disconnect and won't connect until the car Bluetooth is turn off and on.
The Bluetooth on my old iPhone worked perfect every time. I thought Bluetooth had standards and should work with any device if it supports the profile.
How hard is it, especially for a company like Google to get it to work.

My Lexus bluetooth pairs perfectly every time, and usually the call will last a couple minutes before I suddenly get no audio going to the car, or the car may say "check handset". At that point, I have to click the Bluetooth button on the phone to switch to the handset. If I restart the phone it usually works fine for a while, then this happens again. I never had a problem with 3 other phones in this car.

I've got a BMW with a bluetooth kit and have similar issues.
The way I've overcome it is to always keep the bluetooth in the car "on" and on the Nexus "off".
When I get in my car with the key fob in the ignition, enable the nexus one bluetooth and it works.
It's a pain to enable/disable the bluetooth on the handset but it works until there's a proper fix for it.
Also i recently got Modaco's Desire Rom on the handset and found the above procedure works without fail.
One other thing I noticed since having the Modaco Desire ROM is that when you're in a bluetooth call all phone audio comes from the car speakers.
Never used to happen with the stock nexus rom or my previous Touch HD.
It's cool but would be great if there was a way to enable the bluetooth audio so phone sounds came through the car speakers without making a call.

I have a very similar issues with my Nexus One and my Lexus IS350. It pairs OK. But if I make a call, the cars display flashes "check handset" and then puts the call through. I can hear the other end, but they can't hear me.
This is a "deal breaker". Guess I'll be sending my Nexus One back for a refund.

I have been unable to use bluetooth to transfer files OR to tether.
I paired it with my MotoRokr speakerphone, and it paired fine, but I didn't use it to see if it actually works.
Regardless, there are obvious issues with the BT that need straightened out.

how did you that?? i have a 2009 vw

My Nexus one will pair with my computer, but it won't send or receive a file. It won't even go to the trouble of discovering my jawbone earpiece. I'm really disappointed since this should be the simplest of tasks that such a wonderful phone should accomplish. I thought it was just my phone, but seeing this thread makes me sad that that nothing has been done and hopeful that it's more than just my phone and, therefore, there's the possibility it will be addressed in one form or another.

Ok, I played around some more tonight with bluetooth.
It works with my Motorokr speakerphone great. I can talk, make calls, etc... works well.
I got the bluetooth tether working too.
I still have not been able to get file transfers working though. They look like they send, the phone thinks it sent successfully, but the computer says the transfer was interrupted. I'm not as concerned about the file transfer as I was about getting the tether working.

paired the nexus one to my '09 Nissan GTR ... works perfectly fine ... everything works as it should, calls come in perfectly each and everytime ... i do however, leave my BT running 24/7 on both the car and phone

Bluetooth A2DP problem -- not playing through headset

Hi folks, I've been having this very frustrating problem with A2DP that I can't seem to find anywhere else on the forums.
My bluetooth headset (Nokia BH-905i) connects to my nexus 4 just fine, and I've been using it to listen to music since I get my nexus in january. But recently, every time I connect my headset, and I go to play any music or other sounds that play through the media channel, it comes out the speaker on the phone. In addition, when I use the volume slider I get the "speaker" icon instead of the "bluetooth" icon that I used to get.
My bluetooth headset has worked fine since the OTA update, it's just very recently (last week or two) that this issue has been happening.
The first time it happened, a simple reboot would fix it, now I can reboot and re-pair the headset all I want, it just won't work.
Has anyone else had this issue?
PS. I will also add that the next/previous track buttons still work, but the play/pause button DOES NOT! Very strange!!!

Am I seriously the only one with this problem?

What music player app are you using? That could be the problem right there. I sometimes have this problem with my JVC Arsenal head unit, but usually disabling and re-enabling bluetooth does the trick. Don't have to unpair or reboot, just toggle BT on and off.
Anyone know how to get the track info to transmit? It used to work with Apollo and Pandora, but it won't work with Spotify or anything else. In fact, it doesn't work at all on the N4

I use DSub, but I've tried google music, and also any other "media" sounds don't go through the headset as well ie: Youtube, games, etc.

have you checked the device profiles in the bluetooth menu? there is an option for phone audio, and an option for media audio, check them both

Yes I'm sure, I've also toggled them multiple times to try and get it working...

I also have this same problem. I'm using CM 10.1 nightlies
For some reason I able to pair my phone but not the audio.
In the Bluetooth settings though I only have the option for phone audio and not media audio. After checking on a couple of forums, it shows that my radio does support Bluetooth streaming through a2dp, but for some reason I cannot get it to work on my phone...
Edit:
It seems as though A2DP is broken in CM 10.1 as in stock android roms. I'm not 100% about this, but thats what it looks like.

Hi,
I do use AD2P audio a lot, and never had this issue (Sony MW1).
I m using exclusively AOSP or AOKP based roms (never use stock CM 10.1 because of how silly big is the navbar), but I can give it a shot during my next flashing session for testing

I don't have any problem pairing the audio. The checkbox goes and the headset actually beeps. It's connected, android just isn't sending the audio to the headset.

Me too

I've got the same issue.
I have tried with both jawbone and jabra headsets, no joy.
If I toggle bt on/off/on, connect the headset and then try playing music immediately I get ~1 second of audio over bluetooth before it goes silent.
I'm currently on PA 3.15 with moles kernel, but am going to try some other kernel/rom combos.
if anyone knows which logs i should be looking at i'm happy to upload them

Not quite the same problem, my music plays out of the phone speaker. Also I'm running stock rom.

If i wait more than 1 or 2 seconds after connecting my headset it comes out of the speaker also, as the bt media connection dies. I only get the little bit of audio if i hit play right after I connect the headset

I managed to find a very strange work around...
I installed this app: https://play.google.com/store/apps/...sImNvbS5tYXhpc3Rhci5tb25vYmx1ZXRvb3RoZnJlZSJd
I turned on the app, and I could listen to music over mono mode (which sounds AWFUL). I then turned the app off, and when I changed the volume with the volume buttons I noticed the volume bar was displaying the bluetooth icon instead of the speaker icon.
My app was playing music, I didn't hear anything, but my headset was still outputting the characteristic 'hiss' of being in mono mode. So I went into the bluetooth settings and turned off mono mode, and now it is playing music through A2DP finally... We'll see if this problem occurs again and I'll see if the same process fixes it again. I'm just glad it's finally working again without resetting my phone.

I just wanted to update my post for anyone else who might have this problem in the future. I've performed this fix once before my last post and I haven't had to do it again, I've also uninstalled that app and everything is still working great.

It worked for me too!
Thanks to PickleHead and his workaround I'm listening again.
Thanks!!!

Media audio VS. Call Audio
Hi,
I have Samsung galaxy S3 with android 4.1.2 connected to my fordAudio BT device.
I am playing music using the original media player that came with the Android.
The BT connects quickly, but I can't hear the media I'm playing.
Recently I have discovered a "workaround":
When I disable the "call audio" (using the BT menu in settings) and leaves only the "media audio" checked, I am able to hear the media play.
If I re-enables the "call audio", the sound mutes immediately.
Does this helps to understand the issue?

I'm having exactly the problem described here, but this solution doesn't work for me. I have a Galaxy S4 and the bluetooth media audio sometimes works when I boot the phone up, but later it doesn't work. I tried this MonoBluetooth app and it doesn't seem to help. When I tell it to turn on the the mono signal, it says the media is disconnected even though the bluetooth module says it is connected to the AD2P device with media audio. On cases where it does connect, it seems to work, but in that case the bluetooth works with out this app fine.
I'm running 4.2.2 and see this on both the MDK and ME7 code base. I'm looking for a good soluton. I tried the Bluetooth Fix Repair on Google Play, but it can't seem to find my bluetooth configuration folders.

I have had exactly this problem for a couple of days with my S4 connected to my Jabra Freeway car speaker. Also in my case, disabling call audio makes the music pass through, but then I can't use the phone via the speaker which is sort of the whole purpose of the thing!
But I just found a simple workaround: I simply called my phone from another phone to check that phone audio passed through with both options enabled. It did. But it also cured the problem: After the call, media audio worked again - with both options checked.

I'd be interested to know if this fixes the problem for any length of time. Occasionally, and usually after a reboot, I can use the media audio, but then it fails when I try it again. Fiddling with the connections and apps sometimes makes it come back on, but usually only for a short while. While it is connected, it seems to stay connected.

Bluetooth Issue ?

i bought a galaxy s6 edge+ yesterday and bought a samsung wireless Level U headphone. i tried to connect it with bluetooth but it was not work. i tried level U on LG G3 and IP6 its work fine. i tried agains on galaxy s6 and s6 edge+ but its not work.
galaxy s6, s6 edge and s6 edge+ have problem with bluetooth ?

I've had bluetooth problems with mine connecting to my car. It will pair and then after 2-3 connections, it will be unable to connect and I have to repair it again. Might be a connected issue that will be fixed in the future.

Do you use a smartwatch too ? There is a known issue with samsung devices when it is connected to Android Wear. Sometimes my bluebux x would stop working and if I press volume up/down, it will start again. Found out that it happens due to Android Wear app. I disconnected the watch from AndroidWear app and never had that problem again!

I am having trouble with my Bluebud X too. They will suddenly stop working even though the music still shows as playing (but it does not play out of the phone speaker either). I have to turn bluetooth off and on, and reconnect again with the headset to make them work (I have not tried the volume trick - will try that next time). I have Android Wear installed but only because I have a Pebble watch - I am not connecting to an Android Wear device. Do I have to uninstall Android Wear? This is a pain - I have not had this issue with any previous phones, including Note 4.

Our Bluetooth range is dropped down.
Keep your device closer to Bluetooth receiver.

I have the phone in my pocket so it really cannot be much closer to the headphones. If that range is too far then it is a serious bug! I also experience regular wifi dropouts where the wifi disconnects and then reconnects for no reason.
These two problems are frustrating as they affect the basic functionality of the phone.

Try this... Uninstall your Android Wear app (since you do not use it) and goto Pebble App and disconnect your pebble from the app. Now try with your bluebud x. It should work fine. These new phones have some issue with multi Bluetooth connections..

So I have been trying this for a while now and the issue still happens. The music will just stop playing in the bluebuds for no apparent reason. The bluetooth connection shows 'connected' and the music player shows it is playing (i.e. triangle) but the player is not advancing (i.e. time on track is stuck) and there is no sound from anywhere. Any more ideas? Thanks.

In my case, the player never stopped advancing. It was only the sound transmission which wasn't working and once I click on volume up/down, it would start working again till next time. For me, it was definitely the Android Wear. Once I disconnected, it would work just fine. Try using a different bluetooth headset, if you still see a problem, you can ask for a replacement to Jaybird. I've heard they're good with their warranty!

Does bluetooth connects automatically?

I do love the phone and despite there are very few minor details i would love to be changed by LG (if any update), i have realized something. You know there are some devices that when you are nearby, and if your bluetooth is on and already has paired with that device before, the device connects automatically to the paired device.
I have a bluetooth FM transmitter in my car; eventhought i did pair with it, after turning off and then turning on my bluetooth, i didnt see it got automatically connected. Could it be that LG didn't implemented that feature, thus, making us go to bluetooth settings everytime we want to pair with it again?

I haven't had that trouble yet. It pairs whenever I am near anything I have paired with it.

I mean, is not that it wont allow me to connect. it does connect to the device and it is already paired, but for things such as a bluetooth in the car to be able to do it automatically, well, it doesnt do it automatically, when i turn on the bluetooth it does appear a floating box to select which one do you want to connect, regardless of whether the device is already paired or not. (Maybe it is a good thing ?) I mean, i activated the smart lock and i choosed that when im inside the car with the bluetooth on and paired to my car's bluetooth it will remains unlocked even when i turn off the screen

I hop into my car start the car couple seconds later my device is paired. I don't touch anything other than putting it in my car dock.

And no. I tried to unpair and pair again and see, but it doesnt connect automatically even though it is paired. I also tried to unplug and plug the bluetooth once again but it didnt connect automatically. Which leads me to the following questions: What lockscreens and securities have you implemented on your device? such as: finger print, patter, pin, google voice, face unlock , etc.. ?

I have knock on and fingerprint on. I have voice, and all my Bluetooth devices as trusted.

Maybe i have way too many methods at the same time, i have knock knock, fingerprint, google voice, and pattern? maybe one of them is not allowing the bluetooth to connect because you need to activate some option?
P.S: On the other hand, my computer gets connected in milliseconds .

This box is giving you a choice of what to connect to? This doesn't sound like an issue to me but expected behavior. Somewhere in one of the threads is a photo someone else posted that sounds vaguely like this. Chances are, you've given your phone more than one choice of things to connect to and it's asking what to do.

Yes. It does. However, my samsung galaxy s4 and LG G3 connect automatically to the bluetooth >> "Perhaps is because im using custom roms in all of them, :silly: .

The 'automatically connect' thing isn't dependent on the phone. its determined by the device you're trying to connect to it. Generally a peripheral will be the one initiating the connect, not the phone. For instance, for a car stero, the car stereo turns on and if the bluetooth mode is what turns on first (as in, you had bluetooth mode on when you turned the car off, so when the car is started it defaults to the bluetooth mode) then the radio sends a signal to the 'last paired device' and initiates the connection. Same thing for BT Headphones. If they were already paired to the phone before the headphones were turned off, then when they turn back on, they try to initiate the connection with that last paired device/phone. You can easily test this by simply hopping into your car with everything paired and playing music. Then, you turn the phone off and turn it back on. The connection usually never re-establishes because the phone usually never initiates anything unless explicitly told to by the user. This is a security feature... You dont want your phone actively trying to make connections with things that it 'thinks' is safe when they may really not be.
Now if you perform the same experiment backwards, where you turn the car/stereo off instead of the phone, then turn the car/stereo back on, you'll see it automatically try to connect. This is because its safer for a 'dumby' device like headphones and stereos to broadcast its existence since it contains zero personal info. Even the stereos that ask to sync your contacts. Because every time you connect the phone it resyncs. and most stereos delete their info once the connection is broken and so many seconds/minutes pass by.
So, more than likely, its your fm transmitter that's at fault. your bluetooth fm transmitter might be using an older bluetooth standard which may not function properly with the newer standards implemented in the V20. Ya need to remember that the Bluetooth radio in the V20 is special. Its not your every day BT. There is only one other phone in existence right now that is like it, and that's the G5. It supports a whole slue of different codecs at insanely higher bitrates. Because its either the fm transmitter's BT tech is too outdated for newer standards/codecs, or it isn't set to auto re-connect anymore somehow.

You dont want your phone actively trying to make connections with things that it 'thinks' is safe when they may really not be.
Now if you perform the same experiment backwards, where you turn the car/stereo off instead of the phone, then turn the car/stereo back on, you'll see it automatically try to connect. This is because its safer for a 'dumby' device like headphones and stereos to broadcast its existence since it contains zero personal info. Even the stereos that ask to sync your contacts. Because every time you connect the phone it resyncs. and most stereos delete their info once the connection is broken and so many seconds/minutes pass by.
So, more than likely, its your fm transmitter that's at fault. your bluetooth fm transmitter might be using an older bluetooth standard which may not function properly with the newer standards implemented in the V20. Ya need to remember that the Bluetooth radio in the V20 is special. Its not your every day BT. There is only one other phone in existence right now that is like it, and that's the G5. It supports a whole slue of different codecs at insanely higher bitrates. Because its either the fm transmitter's BT tech is too outdated for newer standards/codecs, or it isn't set to auto re-connect anymore somehow.

In other words,,, i need to buy a new bluetooth fm transmitter HAHAHAHA . well. time to sell the old (8 month old though).

It really just depends though. the LG V20 and LG G5 use Qualcomm's special BT chip which allows for "Aptx HD" audio streaming along with some other very high bitrate codecs. So it could be an issue with the FM Transmitter not being compatible with this and thus the V20 just goes 'nope, i dont want you'. While it also depends on the type of BT the transmitter is using. If its using 2.0 it may just not play nice with 4.2. Even though BT is supposed to be backwards compatible and all that jaz, it doesn't mean that 'every thing' is actually compatible sadly... what i'd do, is search "aptx HD" into google. there is what amounts to a 'product page' for it by qualcomm. it lets you see all the devices that are compatible. So once you're there, I'd have a gander at their FM Transmitters. there was I think 2 or 3 there when I looked yesterday. I did alot of research into this thing the past few days cause I'm getting the V20 and thinking about getting the LG Tone headphones that support aptx HD

I just bought the LG V20 and noticed the same thing... BUT instead of going over what BT devices didn't auto connect (none of them auto-connected), I just tried restarting the phone (power off, wait 10 seconds, and turned back on) and now it is automatically connecting to my old Jawbone headset. I have not tested it with my other BT devices that weren't auto-connecting before I restarted (I'll probably go back out to my car tonight to test it). I will report back if they still don't auto-connect.
Update (Fix): I don't think it was the restart, but I got it to work. I had to go into BT settings for each device, and make sure they all were enabled for "call audio". If "call audio" was not enabled, my devices would not auto-connect. I have now tested this with three of my BT devices, and they all auto-connect as long as "call audio" is enabled (media audio setting doesn't matter):
Jawbone Era
Flexsmart x3 BT FM Transmitter
Artic BT Stereo Headset
All of these devices are a few years old and two are ultra inexpensive, so no ultra high-end tech here.
I have not tested to see if I try to use my headset for calls with my BT FM transmitter for media while both having the "call audio" enabled. I hope this is not an issue. I usually listen to the news on my phone through the car's radio, and if I get a phone call I turn on my BT headset. My FM transmitter's mic sucks, so I have to use the BT headset when in the car. I will check this out tomorrow.

Samsung S8 Crackling Bluetooth audio and Bluetooth Codecs

Hi Guys.
I've seen a number of posts on this subject so here's my story and my experience thus far.
I've been using an iPhone 7 since it came out. I've been very happy playing music in my car (Fiesta with SYNC2 system) all this time. My significant other has been using an S8 for some time, and her music always sounded 'crackly' (for lack of a better word) in the car. I thought this was just her Spotify or something.
2 Days ago I bought my own S8 and I had exactly the same issue.
Now from some research I've been able to deduce that this is down to the Bluetooth Codec the phone uses. I changed mine to aptX yesterday and the music quality was great. Didn't sound like a 200KB MP3 downloaded in the early 2000's anymore.
However...
Last night I had to reboot my phone for reasons, and the developer options reset completely, which I believe is normal behavior. But now I can't set my Bluetooth Codec anymore? I change it, the moment I close the menu, it reverts back to SBC. I tried this with Bluetooth off, Bluetooth on and not connected, Bluetooth on and connected, no joy. It keeps reverting. Same goes for all the other Bluetooth settings (i.e bitrate).
So gentleman I ask you humbly, wtf? Why does the settings not stick and is this normal behavior? Is there a way I can force it to use AAC or aptX once more? I really have come to enjoy this phone but playing music in my car is a very very big factor and since AUX and USB (can't seem to play Apple Music/Google Music via USB) isn't an option, I'm stuck with Bluetooth.
Thanks in advance,

Have you made sure dual audio is disabled???
If not, go to Bluetooth, turn it on, hit the tripple dots in the top right and tap on "Dual Audio"
Make sure it's off and now try changing to AptX or whatever codec works best for you.
Disable / re-enable Buetooth and see if it sticks. (Try rebooting too)
Also, Bluetooth codecs will automatically change if the device you're connecting to doesn't support your choice of codec.
Keep me posted

Hi Corey,
Thanks for the response. Unfortunately, the above didn't work Dual audio was disabled, I enabled it and disabled it again. I tried changing the codec and bit rate but the result is the same, the moment I close the menu or turn on Bluetooth, it reverts back to SBC and Best Effort bitrate. I should mention that when I turn on the Bluetooth, it doesn't connect to anything, the only paired device at this point is my car.
Interestingly enough, if I don't close the menu but just hit the middle button, the settings will stay as is and the audio is great. What I haven't tried yet is closing the menu after a 'good' connection is made to the car. It may be that the setting sticks but the menu says otherwise. But I can definitely confirm that if I close the menu and then connect, the audio is garbage.
As for the compatibility of the car's Bluetooth, well it's a Ford SYNC2 system which from what I can see is actually quite basic. I am starting to this the problem isn't as much the codec, but rather the bitrate at which the phone is playing/sending music across the Bluetooth.

I'm not gonna' lie, I'm not very impressed by the Bluetooth on the S8... or Bluetooth in general.
It's lousy most of the time, mine always distorts and especially around emergency vehicles... (Could be interference from their coms???)
If possible, just stick to good 'ol copper wire
I can't imagine wireless audio not ever being interfered with and will always stay wired.
Also, try a music app called Poweramp.
It has many settings involving latency etc. It has a trial for 2 weeks and is worth EVERY penny if you decide to buy IMHO.
Try the build version first, if that doesn't have settings that you need, try the alpha version.
It has lots of latency settings etc
I'm guessing higher latency = better results as it has more time to be pushed over BT before the sound is reproduced.
I'm probably wrong though.
Can't beat lots of settings tho aye.

Morning Corey,
Yeah so my situation at the moment is to have my old iPhone in the car at all times as a glorified bluetooth player. I've also gone out and bought an auxiliary cable for when the iPhone's battery dies on me (happens more often than one would think). And to have a charger for the iPhone, charger for the Samsung and aux cable for the Samsung all plugged in becomes really messy.
It must be something to do with the Bluetooth 5 feature. I don't know what version the iPhone is (cba to check) but it works like a dream.
Wish we had some form of backwards compatibility or a feature to force an older version with Samsung. Just sucks buying a phone which is really not cheap in ZA just to have the music sound like a 300kb MP3 played on Winamp with the treble bars turned up all the way.
I'll try out the app you suggested mate, thanks!

No worries and if you are referring to a USB cigarette lighter charger/USB charger then try the multi-cables.
Try one of these: https://www.amazon.co.uk/Poweradd-L...coding=UTF8&psc=1&refRID=59QBSADVWM0NKGZGTQ4K

sorry to drag up an old thread, i have the same problem ( sync2 too) and it is same issues. I have noticed that even though its bad its tolerable bad. then i add my samsung watch and becomes awful.
did you ever figure the issue out? i feel its the sync2 causing some kind of problem

I dont know yet I have been using my s8 and bluetooth audio for watch speakers controllers everything and today for the first time my speaker was crackling under bluetooth
I will most def be trying to recreate this and figure it out cause it was very iratating...
