[Q] Bad echo on Bluetooth car kit (CK-7W) - Galaxy S I9000 Q&A, Help & Troubleshooting

Hi all,
I have installed a CK-7W bluetooth car kit in my car which works fine.
The issue is that the the other side can hear a bad echo when they talk. I thought it was because the volume was loud in the car but it happens even when it is soft. They can hear me perfectly.
I saw a similar thread in the HTC desire section and apparently someone said it was gone after he upgraded to Froyo. Unfortunately mine is still there.
Some other thread had a fix in WM by changing the class from smartphone to normal phone and I tried to edit something in the ETC folder like someone suggested but no luck.
I would like to hear from anyone using a bluetooth car kit and obviously how it can be fixed. I have not tried any other phone but someone did mention that it works fine with non Android phones.

Hello kar200. I have that exact same bt car kit and I have that exact sale behaviour.
When I talk it's fine for receiver, but when receiver talks she complains about bad echo. Nobody complained about echo when I used Nokia E72 with this car kit.
I'm guessing it could be a delay from speaker which goes to microphone and caller hears her own voice from my mic.
Sorry, but I haven't found any solution. I really hope I find though!

Thanks for the reply. Apparently the echo is not due to any lag and it is to do with the phone. Someone even said that he used a bluetooth headset and had the issue (cannot explain this really).
Apparently the phone should filter the incomng voice somehoe but I don't know how. I might do a test and mute my speakers and see if the echo is there. Another thread on the desire HD said that it is only with the HTC Sense Roms. This might be the case with us as well with the Galaxy's? Hopefully we will see Cyanogenmod on i9000 which will give us a good indication if it is only the Galaxy's roms.

Echo with car kit(wired Version)

had a car kit fitted(wired) callers are getting an echo when talking to me. also will not cut radio out when ringing only when i answer. tried various things upgraded ROM etc and radio(1.04.00) had system checked out by installers and works ok with other phones. points to the phone itself anybody any ideas !!!!
THB Bury Echo
had a reply from THB
many thanks for your enquiry regarding our THB product range.
Some PDA´s or mobilephones like the XDA IIi doesn´t support a radiomute
if you only have the ringtone only if you answer the call. This cames
because this phone´s doesn´t give any signal to the carkit so that this
know that it must activeted the radiomute. Also we know for echo
problems for the XDA II i, thats the reasen why our carkits have no
official release for this PDA and the cradle that you use. In the moment
we have not planned to produce here a solution because the are not
enough request for carkits for this typ of PDA.
Independent from this, the echo self can be amplify if you use more then
one carloudspeaker or that the distance between microphone and speaker
are to close.
if anybody else with this problem could e-mail them also hopefully they will be forced into sorting a solution out as nobody else seems to have come up with a suitable answer!!!!
Hi
I have the same car kit, but only sometimes get the echo - have replaced 2 PDA's, and three cradles - no difference? Any other responses?

Mic of IS, Noise Cancellation disorder!

Just like some other models, the famous Noise Cancellation problem arrived IS.
Situation:
When a normal headphone (without mic) plugged in, or
When the handset is plugged to car kit
Problem:
Noise Cancellation activated and the other side cannot hear anything.
Workaround:
Unplug your phone and talk to it direct. Are we using a smartphone or stupidphone?
Solution:
1. Pray someday HTC will release an update, or
2. Pray someone can root IS and release an utility to deactivate Noise Cancellation
For 1, everyone here please test for yourself, and report to HTC support. I am not sure if they will release an update but at least they are polite enough to talk to. For 2, just pray.
all i use is a bluetooth carkit and that doesnt seem to have these problems for me at all...
idk if ur referring to a cabled one... but if thats the case erhm.... sorry idk ^^

Pay attention to the word "plugged". Yeah... bluetooth stereo headphones are fine too.
Hy! i have my IS since a week... i have the same promlems, nobody can hear my on the other side while i am driving....
when i am calling from home its alright. I dont understand how is it possible? please somebody help me!!!!!!!
I called HTC support about this issue and they replied it's a "feature" of the noise cancellation function. I really hope IS can be rooted soon so we can sort out the problem ourselves.
Same here, they gave me the same reply. But then I asked, is the "feature" intends to prevent user from using headphones or car kits, they cannot give me an answer but said they forward the case to the engineerin dept. Hope something can be done next.

Same problem here.
Fixed by Gingerbread!!! Yay!!!
Are you sure?
Yesterday I've talked to HTC germany and told them what they have to do to disable this crap feature.
Every HTC since Nexus One have this Problem.
It's in the build.prop, you have to change one single line...
On my phone it's now working fine, but I'm S-Off and rooted.
I've told HTC yesterday how-to fix this problem.
They say, that there are to few persons, who told there this problem.
Yes, I can also confirm that the GB upgrade fixes the mic problem with normal headphones.
Besides, I can no longer hear that little echo of my own voice I used to hear during a call. Just hope HTC didn't disable noise cancellation as a solution for this.

[HELP] use internal phone mic on Bluetooth

Hi,
I have samsung vibrant, and have car stereo with bt handsfree, the problem is that the microphone of the car stereo has bad quality, the other side can't hear me.
The vibrant's mic is very good even if the phone is far away
My question is how I can disable bluetooth mic and use the phone internal one? Only the audio from the phone will be routed to the car stereo?
I searched all over the net but nothing, just a lot that searching solution like me.
Searched in android api for microphone disable,there is only mute procedure, no route/disabling.
Maybe some hack, I played with audio service menu of the sgs not found something there
Don't want use aux port for this
Please developers put attention that thing is usefull for a lot of users
Thanks

Htc One Bluetooth issues

Hello Everyone I am here to find some answers (hopefully)...
So I got the HTC One Coming from the Iphone 5. I've had numerous Android devices before, and apple products. I just recently also purchased a subaru wrx, it has bluetooth radio. When I had my iphone 5, i synced perfectly with the radio, hands free worked Awesome. When i got into the car my spotify or pandora would immediately start playing..
Now i get my htc one, and i pair my phone with the car, but my hands free audio sounds terrible, i can barely understand what the other person is saying. On top of that i have to manually connect the phone to bluetooth everytime i turn on my car, its very annoying. I have tried many different roms, and kernels, and i even went back to stock but i can't seem what the problem is. I am about to change the radio in the car thinking its not very user friendly with android devices.
If anyone can point me in the right direction that would be awesome. I am pulling my hairs, i love the htc one, but i miss my handsfree bluetooth functionality. I have tried searching the forums, but i haven't found any answers that worked.
I am having the same issue with having to manually confirm the Bluetooth connection in my car. Mines on a Toyota 86 with the GPS in dash, I believe it's made by eclipse who supply Subaru?

I have to manually connect each time to my bluetooth nakamichi speaker.
I too am having same issues. I also have a 2011 WRX with original radio. With my prior phone (GS2) I connected without problem and automatically every time I started the car. I have to manually connect the HTC one every time. Many others seem to not have this problem with other vehicles, so I'm starting to think it's the Subaru radio not playing nice with the phone. Please post if you find a solution.

I installed an app called Bluetooth file transfer that fixed the issue somehow.

I had similar problems in my car with an alpine radio, but with my galaxy s3.
In fact the thing is that when you register a phone on your radio (in my case) the radio just looks for the first one defined and registered to autoconnect.
Now, if in your radio you clear registered devices list, and try to register your htc, i am pretty convinced that it will autoconnect all the time.
Hope it helps,
Regards,
Nicolas.
My HTCone synched immediately with the OEM bluetooth in my 2011 Kia Forte. No problema, in fact, it is a much better connection (clarity) than with the old EVO 4g, which initially required a bit of fiddling to make work. Hands free phone call system on the KIA works very well too. FWIW.

Thanks for that. I sorted out how to BTconnect my HTCone<--> Macbook, but could only do so, one file at a time. The app you mentioned works great (!) and allows me to push multiple files at ne time. Reviews say it is also a great file manager, that I have yet to determine but if so, an added bonus.
I am also having a problem with the HTC One bluetooth in my car. The phone connects to the car’s bluetooth system, pairs properly, although very slow, it uploads the phone book and call history. The problem is the call quality. The people I am calling complain about the sound, they feel the volume is too high and this distorts the sound, as well as there is too much noise added to the voice, or something like that. As soon as I switch to the phone speaker the sound that they hear gets better. This makes me think the bluetooth on this phone sucks. One person suggested the interaction between the noise canceling and main microphone is mixed up, but if I am using my car's sound system it should not use the phone's microphones anyway, or maybe it does? I guess what I am trying to say is that when I am using the car's stereo it should use only the car's microphones and speakers , but sound like the phone noise canceling microphone is still active.
If anybody has ideas for fixes, or suggestion for further tests, I will do it.
P.S. I didn't have any problems with my car's bluetooth with my iPhone 4 or Nexus 4.
Same for me. Sometimes the problem disappears. I assume the problem comes from the BTstack. In fact, the one is the only Android phone I know that use a different BT stack than blueZ. This stack is HTC one. It allows us having avrcp 1.3 (The name of the song displayed on our car audio). I hope the HTC one Google edition use blueZ stack. I will try a Rom based ion that. If the problem disappears, it will confirm the problem come from HTC stack.

BT problem
Hi,
I'm also having a problem with my BT while paired to the BT in my awesome Volkswagen sirocco.
I don't see any contact or missed calls or recent calls. The log is empty.
Any help will be much appreciated.

I am having the same issue...I had the Motorola Atrix 4g and it paired immediately with my Pioneer deck. That phone always reconnected and like you mentioned, pulled up Pandora etc. Now I have the HTC One, and it paired and connected but it refuses to play audio. Handsfree works (kinda sloppily, also like you mentioned), but the Media Audio portion doesn't work even though the phone reports that it is connected. My stereo says no device detected when I switch to BT Audio. I hope you find a resolution to this issue, I have searched everywhere and of course I saved the best for last and decided to finally check here @ XDA.
I posted earlier in the thread that I was having difficulties pairing my One with my Subaru WRX factory radio. I could not get it to automatically connect with the phone each time I started the car. I could manually get it to connect but that was a pain every time I got in the car. I was able to solve my issue by deleting every other pairing the radio had with other prior phones. I deleted any pairing my One had previously and then paired it with the car radio before any other device. It now connects regularly every time I start the car, and both audio and phone functions work perfectly. I would recommend anyone having blue-tooth issues to try the same. The Subaru radio also had a weird menu system that was different whether I was pairing the phone by using voice commands or trying to do it with physical buttons on the radio. Very confusing but going through the hands free voice command menu seemed to pair both audio and phone functions, where I could only pair audio functions when using the physical buttons on the radio. Seemed like two different systems.
Been having crappy noise issues with my 09 Acura TSX. I emailed HTC regarding this problem but, of course, their response was to 'check with the car manufacturer'. Will try that method and see how it goes.
My problem is a bit different. My htc One connects flawlessly with my JVC unit that too automatically. But it keeps disconnecting and reconnecting. And that is a major issue. The phone also gets insanely hot in this process and today the OS crashed two times and i had to do a Hard Reset.
I am coming from an iPhone 5 on which bluetooth streaming was flawless.
Anyway to stop the auto-disconnect and re-connect going on.
My Bluetooth is mess up.
It can pair up, but the Address Book is not showing up on the car screen menu now. I don't know what happened. When I play music on my phone to the Bluetooth in the car, it is silence.
Does anyone know what is going on?
HTC One Bluetooth Problem in BMW
I am having the same problem.
My HTC One connects, I can make calls from the phone and the calls are clear, but I cannot see my contacts.
I have emailed HTC and they say it is the car (BMW 5 series). I have checked with BMW and there isn't an update for my car available. I am therefore, using the latest software. I previously used the HTC sensation which worked fine in the same car.
I am wondering if one could install an older version of the Bluetooth and A2DP software as the those on the HTC One do not work in my car and I cannot see BMW developing any updates and if they did, the cost could be as much as the phone.
Would appreciate any help

I can now see my contacts after more than a month!
I did many things, some of which I do not believe had anything to do with the process required.So I will stick with the main points and if this does not work I will include all that I can remember.
I unpaired all phones in the car (including the HTC One)
Pair the HTC One
Look out for the message BMW wants......................... contacts
Select yes
Wait for the contacts to load, this took a couple of minutes at least.

Been trying to find out for the longest time the definite set of codecs that the One supports over bluetooth. Besides SBC and AptX, does it also support MP3 and AAC??
The reason I'm asking is that I'm coming from a (company supplied) iphone and have been generally very happy with the bluetooth audio quality to my car's audio system (Audi) and Bose Soundlink Mini speaker. I know for sure the iphone supports AAC and due to the quality suspect it is used in both cases.
The Bose at least does *not* support AptX, however getting a definite codec list for the Bose is also impossible. I only managed to find buried in the offfical bluetooth certification pages that it is a BT2.1 device.
Why do all these manufacturer's hide this documentation?
Very disappointed to find out that the Bose Soundlink Mini negotiates a link with the HTC One using SBC...
These are both premium devices for which top dollars are paid, and they still shovel this **** on me.
I'm not sure on where to place the blame here, HTC for only(???) supporting AptX next to SBC, or Bose for only supporting SBC(???)
As mentioned, both are not transparent in their devices capabilities - isn't there an app to find out these things?
Beats is at least more clear: "Bluetooth 2.1 audio and supports SBC, aptX, AAC Codecs for high quality streaming"

Dialer - Bluetooth Audio Source Switching

My gut tells me this maybe a lollipop issue in general.
*On a call
*Another call comes in
*Nexus 6 switches audio source to handset
*Call is no longer on my Bluetooth earpiece
This can happen too when email / SMS arrives. I read about a lot of car BT based issues...this is just in the headset now.
Anyone out there feeling this too?
There is a problem with Bluetooth in Lollipop or the Nexus 6

Not many people use BT in their car or daily life at this point in time. Can't tell you how many people I see driving around with a phone in one hand and a steering wheel in the other. Kind of like people here in the USA that don't use cruise control on the highway when clearly you know that their car has it. But I've been hands free in cars for over six years in fact since the HTC HD2 came out. I realized at that point, that to be safe one must use BT and have equipment in car to support this. It's becoming a law in most states in the USA but not all and is not enforced by law as much as it should be, but those times are going to change. There are some forums on the web that talk about bluetooth in lollipop and many of them are confused and think they know what the problem is, but none have proved it yet. There are also other sources that claim BT is on it's way out, I don't know about that. But yes, there are some weird things happening with bluetooth if you use it a lot. I don't know what the answer may be to your problem but you might want to try a search on google to find out more information about this issue. Good luck.

Interesting perspective and ty for taking the time to post this.
Back to the point though; anyone out there having these types of specific challenges with Bluetooth on the N6 as I described above? It really makes this phone unusable for me @ work.
Yes, I also use BT in my vehicle. It used to connect through my car speakers automatically, but now im finding that when making/receiving a call, I need to manually tell it to switch to car speakers. I mean, why the hell would my car speakers stop playing regular radio when a call comes in and to make me still use my handset to talk/listen?having to manually switch to car speakers is dangerouse while on the freeway.

I was experiencing something similar.
I had a 2009 model Pioneer AVIC-x910BT headunit in my truck. And bluetooth worked fine until I got my Nexus 6 (coming from a Nexus 5 and Nexus 4). The Nexus 6 would mute my car audio properly, but when I picked up the phone, the phonecall was on the phone and not the car speakers.
I have the same car, but now I have a 2015 model Pioneer AVIC-8100NEX with Android Auto, and have not had one BT issue yet. I am assuming that the issue was either the N6 or Lollipop5.0 was having issues with the older BT technology my old radio used. Now that I have the newer radio, no call issues yet.

Could you share the model and make or the car?
to confirm my understanding,the call audio was on phone speaker and you had to manually select the it every time?
Was this working in the past for you?
Does this happen for every call or only during multiparty call?
I am now using a different BT headset, Jabra, and the model is at least a year old. I think I am going to look for a completely new model of bluetooth headset / earpiece that came on the market much more recently and see if this makes a difference.
I have been using a wired headset to avoid these challenges, but very much miss hands free use for phone calls. Anyone else feeling this issue out there?
Delete
It has happened to me as well. I use a Jabra Tour BT speakerphone, while having music streamed via a BB BT gateway to my car speakers When on the phone and another call / sms /email comes in, the phone connection to Jabra Tour is dropped, I have to manually reconnect (but after reconnecting to Jabra the phone call ends, somehow the media stream switches from BB gateway to Jabra = more manual switching). Unsafe to be doing this on a highway. My Galaxy Note 3 and prior to that Galaxy S3 worked perfectly well with the same setup.
I understand that Nexus 6 takes advantage of the new BT tech, but it should have been made backwards compatible with the older BT devices.
