I always use my bluetooth headset when talking to family and friends(due to the length of time, hate holding phone). Since, I switched from my nexus one people have griped about the interference/noise they hear when I'm on my bluetooth headset. It is not my BT headset as I've tried a few(motorola S305, and two smaller bluetooth earpieces), all of which exhibit the noise. I was wondering if anyone else has had this problem ?
Running the Galaxy S I9000 ROM rooted.
Everyone complains about hearing me whenever I try to use a headset. Seems like the stack sucks or the radio is terrible.
Got the same problem. My bluetooth calls are loud and clear on my side, but everyone on the other side complains about static noice and I sound very distant.
I tried the original ATT rom (stock unrooted) and the most current 2.1 that is available for download. No difference.
Any ideas what to try to remedy this?
I haven't noticed anything like this on my Motorola S9-HD headset.
I have noticed sometimes it will cut the music every once in a while, whereas my iPhone never did.

This is a known issue with the I9000 ROM... Bluetooth doesn't work well for some...
I'm running the stock rom... is that the I9000 rom?
None of my friends have mentioned such a problem when i've called them, although I've only made bluetooth calls a couple of times (including on the bus and at home).
Using after-market Nokia BH-503s.
I'm definately seeing the same problem on the stock rom. Not as bad as athe I9000 ROM but still bad enough for them to complain. Seems like it's made worse by the different roms/kernels we've been flashing but there's definately a problem.

I'm seeing similar symptoms, except my music cuts out every 30 seconds or so. My setup is a Kensington iPhone adapter connected through aux input in my car with an Anycom FIPO on the iPhone adapter (it converts the iPhone/iPod adapter into a bluetooth receiver). I then stream from my Captivate to the adapter and it works fine except that it cuts out every 30 seconds. Did you ever figure out how to fix it?
UPDATE: Just wanted to add that I figured out what was causing my problem: having Wifi turned on. Once I turned it off, my bluetooth streaming worked beautifully, with no hiccups.
Still have a problem with this. Stopped using my BT headset completely... sucks having this thing stuck to my head for calls.
I have encountered several problems:
Party can not hear me at all; though I can hear fine.
Party hears tinny sound to my voice.
Headset disconnects while playing music.
Using a Motorokr S9-HD. Works fine with Samsung A-737.
I too have the static problem. This phone sounds wonderful on my end, but everyone complains that that can't hear me! This is so far the only complaint I have.... I hope someone will have a fix, or come up with something.
I have this problem too !
Hey everyone,
Found out my company is ditching Sprint for Verizon which means I have to part with my beloved Nexus 5.
Anyway, from what I've been reading on here it seems like the M8 is really the only Verizon phone that can be rooted. I've had a few HTC phones over the years, including the M7, but they never seem to get along with my car's stereo. The phone part works fine but when I stream music via Bluetooth there is always a great deal of distortion in the high end. Especially on cymbal crashes. This makes it pretty much unlistenable. I'm curious if anyone has experienced anything like with with the M8? I've Googled it a few times and found threads about the One X and One M7 having this problem but have yet to see anything about the M8.
I don't stream to my car often, but on the handful of times I have, I didn't notice any sound issues. This was using Pandora and Google Music, on a Ford (2008 model).

Just got my jaybird x's today and guess what. Filled with static. I could not be more annoyed with this particular phone right now. Three defects in one model I mean come on. Speaker crackle. Screen is creased and looks like you're pressing down on a TV and now Bluetooth has static

I can't say for certain, but I imagine bluetooth audio issues would most likely be due to whatever is actually playing the music, not the phone. Bluetooth audio, in general, is terrible - unless you're using something like the HTC Stereoclip which does not use that same audio codec that just about everything else does. You could have lossless flac files on your phone, and 9/10 times it's gonna sound like crap over bluetooth, no matter what the music is being sent from.
I stream daily over Bluetooth and it sounds amazing. Vzw.

Just plugged mine into my aftermarket JVC GPS stereo on a my truck which gets only occasional use these days. Have to say I was somewhat blown away when I pushed some Comfortably Numb into the 5 speakers (Inc sub) and cranked up the volume. Most impressive...
The wife gets terrific sound from her N7 to some small bluetooth speakers we got last year and has no issues unless she's using TuneIn at which point it goes from OK to awful.
I say this to simply point out that the invariable rule of YMMV seems to hold sway here but I don't think the M8 has any generic systematic failure with bluetooth audio.

This is true. But I'm talking hiss/distortion like a speaker is blown. I'm just streaming Spotify to my cars stereo and not expecting flawless audio but the issues I have with the M7 were unlistenable.

From what I understand, it has something to do with HTC setting the bitpool value too low. Which, in itself, might not be a big deal but it might just be a issue with that value combined with my car's stereo. I just don't want to lose root when I move to Verizon.

Maybe the stereo in your car just sucks? Streaming Pandora over BT in my car usually sounds great. I mean granted it's not as good as using headphones, but it sounds pretty damn good.
Also, I streamed some more over this last weekend, and while the quality was still good, it did disconnect once for no apparent reason. And once it happened, I remembered that it happened a few weeks ago as well. Same thing, I was just driving along both times, and my BT just seemed to shut off. I turned BT back on, reconnected Sync (it's damned annoying how Sync never automatically reconnects), and it worked again for the rest of the weekend.

I saw that an OTA for the M8 pushed out today (I think) that was supposed to fix some Bluetooth issues. I won't if the disconnects were addressed.
I'm M8 should be here on Monday. I really hope it works out OK. I don't want to send it back for an iPhone. :crying:
Another OTA? Has anyone else heard this? I am having a really rough time with bluetooth headset outgoing voice quality so some sort of fix would be awesome.

If the phone volume is at max it will distort. When I turn the volume to max while streaming Bluetooth to my car stereo it sounds crackling and distorted. Turning volume down 2 clicks to about 85% on the phone fixes it

It's not a volume thing. I've tried turning it down when I had the M7 and it sounded the same.

Again, sorry, but it may just be your stereo. When Bluetooth streaming to my car I always have my phones media volume maxed and I control the listening volume via the car volume, and it sounds fine.

Do you have an aftermarket stereo? I've had 4 different head units on my car, all high end Sony and clarion and all had same thing with max volume all my previous 3 phones ( rezound, s4, and m8). Just curious if it's just aftermarket decks that have this issue which I really don't consider an issue. I prefer to have the volume lower on the source and let my deck and equalizer provide the output anyway.

No, it's a factory Ford stereo. If you know someone with a factory BT compatible stereo, maybe try pairing your phone to their car and see if streams with or without distortion?
I mean, it's possible your particular phone itself could be bad. I just don't think it's all M8's since I don't have a problem, and because I imagine we would have seen a lot more complaints.
For six months I have been playing music in my car with a one (M7) via Bluetooth, with very annoying vibrations that eventually damaged my car stereo. I just found out that if I launch the media app via the "HTC car" app, the volume is much louder and I don't have those vibrations anymore. By default the HTC car app in the M7 only includes the default "Music" app, but other media apps may be added.
Hope this may help for the M8 too.
By these vibrations detroyed my car stereo, and I had to change it. I am pretty annoyed that HTC doesn't mention this anywhere, and leaves it to the user to find out.
I just got the tmobile variant s6 and immediately went to test the Bluetooth audio stream on my 2015 gs350. I noticed a crackle in the audio. It is minimal but quite noticeable at high volume. This is disappointing as my Sony Z3 had excellent BT audio quality on my gs. Anyone else notice this?

I do not seem to have that issue over my car's bluetooth. T-mobile also.
I'm getting good audio quality via my Sony SBH80 aptx BT headset. Perhaps you can play on the Sound Alive equalizer.
Just wanted to let you know that I am having this same problem. When streaming music in high quality from Google Play, the treble is all crackly and distorted. It's really disappointing. I'm going to do some testing today against my old m8 and using non-streaming music. But never had this issue before.
It's probably the fact you are streaming audio. Try some high quality downloaded music, like from Spotify. I've no issues at all.
I am also having the same issue with the Verizon version of the S6. It sounds terrible over my car Bluetooth when streaming but sounds good through my bluetooth Bose headphones. I didn't have any trouble with my car Bluetooth with my iPhone 6. I really hope Samsung gets this sorted out with a software update.
I too am having issues with streaming bluetooth. I think that my issue with it is amplified, because I normally listen to music only on my Magnavox Turntable, and the sound from that console is unbeatable by any electronic streaming or mini-speaker. My son bought me a bluetooth speaker for my birthday last year, which was very nice of him, but the sound just does not compare to the 1970's technology.
Maybe I'm just old.
Do you happen to have any bluetooth le devices, like a fitbit, attached at the same time? I tried disconnecting my garmin vivosmart and there's a dramatic improvement.

Same here. Lowering the treble help a tiny bit but what's music without treble . I've tried disconnecting my pebble watch but no dice. I really don't want to go back to aux.
In my car, before I disconnected the Garmin, I found that adjusting the toggles in Play Music - edging the first dial two toward Treble and the other dial three toward Instrument helped a bit.
I noticed the crackling on treble as well. As evanl81 suggested, I disconnected my Moto 360 (switched it to airplane mode), toggled the phone's bluetooth to have a fresh connection to the car, and the crackling is gone by at least 90%!
Very disappointing. Didn't have this problem with my Nexus 5. I'd very much prefer to not have to disconnect my watch every time I get in the car

That would be a problem. I'm starting to think that we are wirelessly connected to too many things!!
So it looks like my pebble watch was the problem. Seems i can't have other BT devices connected while connected to my car. Once I put my pebble in airplane mode, then off/on the BT radio and all is good! Sucks but at least it's a workaround.
I'm trying to use AutoInput and Tasker to automate the disconnection and reconnection of my watch when connected to the car bluetooth right now, still working out the kinks though. :\ Endless little things and inconsistent behavior.
It would be fantastic if this gets fixed by Samsung at some point!

No, I have a Nexus 4 with 5.0 and now with 5.1 and its connect to LG g watch, a parrot ck3100 and auki bluetooth reciber and the quality is perfect. With S6 I only connected to my LG g watch and auki and the audio quiality is a ****.
i don't know about bad audio quality for bt but i get audio cut outs and choppiness when using my jaybird bluebuds. it gets really annoying. i noticed it happens in wide open spaces too like when i'm outside but not near any walls or enclosed areas. if i'm indoors, it works perfectly fine. i remember reading about the way bt works and the signal needs to bounce off other surfaces or something like that in order to work properly. i had this same issue way back in my OG Droid days and there was a build.prop edit to boost the signal by giving bt higher priority.
anyone else have this problem? i'm on VZW variant btw.
other than this issue, bt audio sounds perfect. i also use Viper to give the audio volume a major boost.
I'm having the same issue on my car audio.
It was perfect with the Nexus 5, very disappointed to have this with the S6.
I just got my sg6 have a samsung gear live and bluebuds x I get crackling sounding high end, very annoying, coming from an HTC one m7 with the same setup and had zero problems, really hope they are able to fix this!
OK so I enabled the tube amp setting and nothing else, it seems to have made a huge difference. I can now listen to music without cringing. Hope this helps.
Ok, I made a few findings about the issue. I also have a moto 360 connected to the S6 and the crackling is so high that is imposible to hear music with a minimum of quality.So i tried with the watch off or in airplane mode and the crackling is still there but sometimes it dissapears after connect and disconnect the bt devices but not always. Now, the elephant in the room:
I have a Samsung Hs3000 bt stereo headset and the music quality is superb even with te moto 360 connected. The magic is that this particular device has aptx codec included. So if you have an aptx bt device the quality its going to be there. For no aptx devices i'm trying an experiment: i remember from the nexus 7 2013 and other android phones that bluetooth audio quality was bad since kitkat and the problem was bluetooth compression was too high. There are two files that control this behaviour: audio.a2dp.default.so and bluetooth.default.so. If we could edit this two files maybe we could fix this. If someone can help me and tell me what program can i use to edit this files on my computer i'll try to fix it myself.

Just wanted to follow up on this thread - I recently switched to the Note 5 (which I love) and also got a Huawei Watch. When the watch is connected to the phone and the phone is connected to bluetooth, the sound quality is really horrendous. So I'm guessing it's something with the BT smart implementation in Samsung phones or something? It's really annoying. I too tried to work out some stuff with AutoInput, but it's a huge pain. The only real workarounds are to put the watch in Airplane Mode or just disconnect through the Android Wear app. And unfortunately there are no shortcuts through AutoWear. Oh well.
I have a Verizon Note edge and I am having issues with my Bluetooth connection. It’s the same issue I had with my Note 3. When I purchased my Note 3 I purchased some JayBird Bluetooth headphones. If I was sitting still and not moving, they worked great. I could actually leave my phone on the table and walk about 40ft from it and still had no issues. However, if I tried to use my headphones while moving (ie walking, at the gym, riding my bike), the audio would skip horribly. Just about every 2 seconds. So then I bought my Note edge and it was happening with this phone too. I thought it MUST be the headphones. I purchased a new JayBird Bluetooth headphones, new model too and the issue continued. I just returned the Jaybirds and exchanged them for some Beats Wireless2 headphones…. The issue remains. If I’m sitting still they work great. As soon as I put the phone in my pocket and go for a walk the issue starts. While walking I took the phone out of my pocket and put it up to my head about 3 inches away and they work just fine. If I put the phone back in my pocket so that it starts to skip again and then cover my ear and headphone with my hand (cupping it) the audio shuts off completely. This leads me to believe there is something weak about the Bluetooth in the phone. This was an issue with my Note 3 and now my Note Edge on 2 different brands of wireless headphones. What can I do to correct this?
I did some Google'ing and saw many samsung users are having this same issue and the ONLY solution is to leave the screen on? and FYI, this happens with my music on my phone, music on my SD card and Pandora so I know the $100 SanDisk 64GB card I have in the phone is not the issue. I have cleared the cache and data for the 2 bluetooth files in the Applications Manager, I have wiped the cache partition of the phone and I am running stock Android never rooted.
Ladies and Gentlemen,
I am having the oddest issue with my phone. The u11 is 99% amazing, to me. I really like everything about it......
-except-
When paired to my 2013 Dodge Dart (don't ask. big mistake) the music audio plays slow. I don't mean the speed of reaction as far as switching tracks or how long it takes to play the next song... I mean it sounds like the audio is pitched down by about 20%.
Things I know/Have Tried from a troubleshooting perspective..
The phone bluetooth audio works fine.
The audio, when connected to the aux jack, works fine.
The audio, when connected to OTHER bluetooth devices such as my HK Aura plays fine.
My phone and car are updated to the latest firmware.
I realize that the conclusion is going to be "it's your car dude".... but since it's not so easy to get rid of the car... and I don't really want to swap this phone out for a Galaxy......
Is anyone else experiencing this? Has anyone had this and sourced a solution?
Thanks.
I've used my U11 in my 2013 Dodge Grand Caravan (don't ask. big family) and it performed flawlessly.
I imagine they are on similar systems, mine is just the standard UConnect head unit. This happens will all media streaming?

Yes standard head unit. strictly an LED display with knobs.
Yes. It's across the board.
Google Play
Pandora
Tidal
Netflix (it's trippy to watch the video move at regular speed while the vocals are not only behind, but pitched down!)
I've also tried varying bit rates on my personal MP3s.
I have a hunch that this has to do with the audio in the phone being 24bit and the radio converting to 16 bit, but I have nothing to base that on...
Basic suggestion - unpair and re-pair to see if that resets something.
I've connected my u11 to two different cars so far (an Infiniti and a Land Rover), and haven't had that issue.
I've also connected to a plethora of BT speakers, with no issue....
It is probably your car. To be honest, I think it's a UConnect issue that doesn't play nice with HTC phones. My HTC 10 had basically same issue I'm having now where music sounds like garbage, distorted. The U11 is even worse! I believe my head unit is the RHB model in a 2011 Ram. But 2 phones now with same issues, can't be coincidence.

The classic, of course.
I did pair and unpair a few times even going so far as to to completely reset the car radio from any pairings.
no luck, but thank you for the suggestion.

I have yet to test my wife's Samsung s8 to see if the issue carries. Not a good test though since the s8 has Bluetooth 5.0 but it's all I've got ha!

I have a similar issue, my U11 stutters and warbles and is generally unlistenable when using my tunelink (for android). However, when playing music through my Bluetooth headphones it plays perfectly, when playing through my Bluetooth speaker it plays perfectly and finally when playing through my Bluetooth headset it plays perfectly. Tried on my sisters car stereo and it plays perfectly. Its just the tunelink that has a problem. Tried a S8 and it plays perfectly through the tunelink, as does my 10 and my M8.
Edit:
Have bought another adapter to test and this also connects and plays perfectly with my U11. I guess it's just a compatibility thing with the tunelink.
Hey I have the same problem in my U11 and 2012 Dodge Challenger (ask, I love this Car!!)
The only solution I have found is if a restart the app on the phone then the playback is good. but I do wish i could just connect it and it would the playback would run fine like my old HTC M9.
Just to add to the thread. My u11 is slow to connect to my 2014 pilot and 2012 infiniti. Why it does connect it always disconnects. I'm on us unlocked 1.16 firmware.
I've read there is issues with Android 7.1.1 and 7.1.2 is better but searching the internet it does not seem the issue is too wide spread.
Edit. Testing with Wi-Fi on, not connected. So far so good
I have similar issues. I have a Subaru Outback (2015) and while my previous phone (Nexus 5) and my kids' iPhones all sound fine, the U11 sounds terrible when connected via BT. It is very grainy, like a sample rate mismatch. Same result in all audio apps. The U11 sounds find when connected to my Bose BT headphones. It's just some weird incompatibility with the car. Extremely frustrating. Its 2017 people!!
