Bluetooth - Voice calls and Navigation - Galaxy S 4 Active Q&A, Help & Troubleshooting

Hi guys,
In my car, I have a Kenwood Kdc-w4737u radio with bluetooth module Kca-bt100.
Allow me to explain what happens after pairing:
1. Bluetooth ON: When turning bluetooth on, S4 pairs and says "in call" (ghost and muted call), although no call and no app is actually running...
2. Temporary fix: Making a phone call actually solves this problem and S4 starts behaving like it should.
3. After the fix, while on Radio/CD/USB, I receive a phone call that goes through bluetooth, end call goes back to radio/cd/usb.
4. Start Navigon GPS, similar problem like in 1. Navigon seems to open a dedicated audio channel that never goes to sleep. Stays silent when no audio directions are playing instead of going back to Radio/CD/USB.
On my Iphone 4 I do not have any of these issues. Turning Bluetooth on does not start a ghost muted call. While on Radio/CD/USB, receive a phone call activates bluetooth, end call goes back to radio. Same with Navigon GPS, new voice directions activate bluetooth, when voice instructions ends, goes back to radio/cd/usb. Perfect.
I already know that the bluetooth on S4 is the latest chip and version and etc, what I would really like to know is if anyone got a fix for this, I have tried a few apps that control bluetooth in the app market and none works.
Thanks in advance.

If you have an S4 and not the S4 Active, you are in the wrong forum.

Hello,
I have the exact same problem from a few days with my car bluetooth system and my S4 (previously it was working flawlessly), did you solved? or at least found something about it?
Thanks

not really
I have given up on my galaxy S4 and went back to iphone 4. Galaxy over time presented too many random bugs with too many of my daily tasks.
If you make a phone call immediately after connecting the bluetooth, the issue is gone UNTIL you disable bluetooth. Next time you turn bluetooth on you will have to repeat the process.
Over time (after a few weeks) I never got THIS issue back, so I never had to make a quick call for it to behave normally.
Also note that Galaxy S4 has a newer bluetooth version, and most car players have the 2.0, which I believe to be the cause of most issues.

Tilt Goes Silent - I think bluetooth related

Hi everyone. I have had my Tilt for 4months now and it has given me a lot of joy. I have flashed and reflashed with no problems at all. I am currently using Schap's 4.31 Rom with 1.27.12.11 radio.
About a month ago i installed a new car stereo that has bluetooth connectivity with my phone - worked like a charm, paired very easily and generally appeared to be working with no probs.
Then i noticed that if i was in a bluetooth conversation and somebody else was calling (on call waiting), if i switched calls i could not hear anything, and if i ignored the second call, when the person on call waiting hang up, both conversations were terminated. I thought it was odd, but i just deactivated call waiting and thought, "let them try calling me later".
The other, a lot more serious problem, is that sometimes, randomly as far as i realised, the phone will go totally silent - incoming calls won't ring, and when i try to make a call, when i press "talk" then phone does not make that beep that it makes when an outgoing call is initiated. Should the person i call pick up i cannot hear them at all.
A soft reset takes care of this problem, but it has happened to me 3 times already, and i think it was after a bluetooth call.
Has anybody faced this problem before? I need to be available on the phone 24/7 due to my work and i really need to find a solution for this. Yesterday afternoon i took a nap for 45 minutes and had six missed calls that i never heard cause the phone never rang.
The phone is always on "ring" and at full volume.
Any ideas would be welcome.
Thanks

Same issue
I'm assuming since I also am facing this same problem that it is not uncommon. It seems to me that it happens after a bluetooth device is turned off. Somehow it sets the volume on everything to mute. I thought only a soft reset would fix it until I discovered that it was just shutting off the volume. Still annoying, though.
Tilt problems with phone going silent
This problem has occurred with my phone every since upgrading to the WM 6.1 and it is related to a bluetooth device being hooked up. Often when someone calls the ringer will go from vibrate to on, but the volume turns all the way off. It will then cycle to off completely. The cycling occurs when a call comes in or when I hang up. I can stop this problem from happening by disconnecting the bluetooth head set. I have tried three different headsets and the problem occurs with all of them (Jawbone I, Jawbone II, and Plantronics) so I know it is not the brand of headset. HTC said to try a download of a screen dimmer problem, but have not done that yet. Anyone have any better advice?
did u guys ever find a solution to this?
its quite annoying missing calls because my phone decides to go silent for some reason
Same issue with GPS
I have the same issue, even when using software that accesses the GPS via bluetooth port. Muting is irritating, but at least voicemail catches messages. What really bothers me is that sometimes the mute is turned off and the volume up, especially when in a private meeting where we do not want interruptions

HTC Tytn II bluetooth causes silent setting
I too have had the issue where my phone will go into total silent mode after using my bluetooth stereo hands-free feature. It doen't happen after using my bluetooth headset though.
It happens pretty regular that after using the bluetooth hands-free of my JVC car stereo that when I take the phone elsewhere it is totally silent. no ringer, no alarm (Ptravel alarm is what I use), no audio if I make a call (or receive a call).
It also will cause the phone to be silent on subsequent calls on the bluetooth stereo hands-free: ie: I take a call, hang up and another call will come in and I can answer it but have no audio.
My Tytn II is running the HTC (AT&T) WM 6.1 upgrade. The only thing I have done is use the Advanced configuration manager and the Kaiser tweak to change a few settings for performance and visual enhancements.
I see others are having the same problems.....Has anyone else used the tweaks and maybe that is root of the problem?
Has anyone discovered a fix (really important). My only options are to soft reset every time I get out of the car or not use the JVC bluetooth capability (which is why I replaced the stock radio in the first place).
Thanks
Hi rrackman,
I'd advice for you to look at the following thread:
http://forum.xda-developers.com/showthread.php?t=438457
It's quite long, so better subscribe to it and wait for responses. Several people with Tilt's have the same problem. Myself I have a JVC NX-7000 and an unbranded Kaiser (HTC TyTN II). It works fine with WM6.0, but I have the same issues you mention with WM6.1. First advice while we're searching for the solution: downgrade to WM6.0...
Regards,
Nika.
Is there a solution to this problem?
Try WM6.0 ROM - check out the thread I mention in my sig.
Regards,
Nika.
I did indeed take a look at the thread you linked earlier. Sorry for making the quick post earlier, I should have mentioned that this is regarding the "unexplained volume drop to zero" symptom, not the NSI symptom. Fortunately I don't have the NSI problem, just the drop to zero problem.
Of course downgrading to 6.0 would be the key solution, was just hoping to find a way to avoid doing just that. My phone never had the problem prior to 6.1 and was running the exact same list of applications and settings.

Bluetooth/Phone Call Issues, Anyone?

Has anyone else been unable to make phone calls after connecting to your vehicle's bluetooth? Most of the time, I can make phone calls without issue. Sometimes, I can't even hear the call ring when I'm connected to bluetooth. Occasionally, when I turn my vehicle off, the call goes silent instead of transferring to the earpiece on the phone. The only way I can fix the issue is rebooting the phone. This has become increasingly frustrating for me, since the issue is so inconsistent.
I'm running the stock ROM, rooted and un-encrypted.
Thanks!
Same here
I'm having the exact same problem you are having with my Ford Touch Sync, Bluetooth has work maybe once. At other times only the music over bluetooth has work. But was unable to make hands free calling! I also made my ford touch sync a trusted device, and the problem with connection still continues! Hope someone could provide some suggestions
Stock rooted- TWRP- encryption removed
I am having issues also. Just today, my phone shows I am connected to my Pioneer Navi head unit, and the Pioneer shows connected to my phone. I proceed to make a call. The audio on my radio mutes as it should, and nothing. No ringing, no busy signal nothing. so i hang up and try three more times. on that third retry, i heard the other party faintly, realizing that even though my radio muted and shows BT connected, the call went through the ear speaker on the phone. When I hung up the phone, my radio unmuted.
Last week, I was having issues where i couldnt hear any rings or busy signals. It would be silent for 20 seconds or so, then i hear the other party say "hello".
I honestly thought it was my head unit, since it is about 4 years old. But now I see others with similar issues on other brand bluetooth systems in their cars.

I just got my N6 today and I'm having trouble with My Ford Touch as well. I can get it to pair and play music, but it won't "connect" to my phone. It's odd because my N5 works fine with it. I would assume the N6 wouldn't be different.
We probably have to wait for an update from Ford, which will probably take months...
EDIT: Well I decided to try it again. I deleted the Nexus 6 entry as well as the Nexus 5 entry. Went through the pairing process again and it worked as intended. Not sure what happened the first time.
I ran into the same problem as others where my N5 worked flawlessly with my Ford Sync in my fusion, but the N6 is terrible.
I love the phone, but this is really annoying. I get into the car and sometimes it connects immediately, other times I have to turn off and back on the bluetooth about 3 times for it to finally connect. Very weird. Ford offers an upgrade to my Sync system, but wants $50 to do the upgrade. Pass.
I might try what the other person did and delete all entries for phones and pair it again. Unfortunately, the weather is pretty bad outside, so it might need to wait a short bit.
Has anyone else had luck re-pairing with their car and had reliable connections?
I use Ford Sync.

I use Ford Sync, and everything works as expected. I am Stock and unrooted. I guess it would come down to what version of Sync. Mine is from 2012. No touch screen. I also delete all other entries on the system and start from scratch making sure that the N6 is the main device.
If I can wake up the screen on my own, outgoing calls work fine

I have a Nexus 6 running Benzo ROM (5.1.1) and I have a GPS Nuvi 3580 bluetooth-enabled which I want to use to make calls while driving. I have added this device to my trusted devices so my phone unlocks as soon as it connected to it.
If my phone screen is on, then I'm able to call anyone from the bluetooth device, no issues. But as soon as my screen goes off, I can't make calls and when I switch on the screen on my own, I see a message "Process system isn't responding. Wait or close?"
Irrespective of what I select on this message, the call goes through. But it totally defeats the purpose of handsfree bluetooth mode. Is there something that is not allowing the bluetooth device to wake my phone up.
Also when I receive an incoming call, I see the notification on my GPS but I can't receive the call in one go. It takes multiple calls for it go through. I have also noticed that my bluetooth device keeps disconnecting and connecting without any change on either the phone or the GPS side.

Since I last made that post you quoted, i purchased and installed a 2015 model of the Pioneer AVIC-8100NEX. It has Android Auto, but can be used with the regular Pioneer UI also. I have had no issues anymore with this new radio. Maybe the BT protocol in the radio is newer? Im not that tech savvy to know. But the 2015 radio had no issues with BT calls anymore, on Pioneer's UI or Android Auto's UI.

[Q] Bluetooth headset issue

Hi,
I've bought a "Jabra Stealth" headset and I'm unable to launch Google Now on my Nexus 6 (Android stock 5.0.1, FrancoKernel r8) with the dedicated button although it's a built-in feature of the headset. I assume that this is an issue of compatibility with Android 5.0. Jabra has answered me that I didn't configure vocal commands well but that's false. Has someone encountered the same problem and has a solution for it?
Thanks

I have a similar issue. I use a Plantronics Voyager Legend. A couple of issues:
1) press and hold of the action button will bring up "voice dialer" instead of "google now". I dont know if you've ever tried to use voice dialer, but i think its more or less deprecated since the nexus 1 was the new kid on the block.
There is an app for bluetooth on the app store that lets you choose what to launch with that button. however, it didnt work that well for me. lots of lag and it blended together with other bluetooth related issues.
2) Bluetooth never seems to "turn off". I have a smart sensor enabled headset. IE the phone should know if i have the headset on or not, and pipe phone calls and notifications and ringtones to the speaker if i dont have it on and to the headset if i do. instead, the phone constantly pipes EVERYTHING to the bluetooth headset. no fix yet.
3) phone connection to my car's bluetooth makes my audiobook start playing. I have no idea why. it is not a setting in the audiobook app. Seems that the fix is to disable streaming media over bluetooth (contacts/messages only)
From what ive witnessed with issues regarding audio, screen brightness, bluetooth, this is yet another half-baked google product with little to no attempt at a proper follow through. just a crap device rushed to market with tons of potential and a complete crap OS and barely any thought or usability effort put into anything except the home screen.
I also have the N6 with the P Legend. I am having issues where the caller can barely hear me. Do you know if you have this issue at all?

When the caller can barely hear you, check your phone. Sometimes, even though my headset is on, the phone doesn't care and attempts to use the phones speaker or mic.

That's my current issue...
I can answer the calls with either my truck or ear piece, but both will randomly not have audio. The phone says it's connected BT, but I have to switch the source to speaker or handset and then click back over to BT. The whole time while I'm begging the person on the other end not to hang up and to hold on a second. Not bad when I'm at my desk with earpiece....let's just say it's a bit more nerve-racking on the highway.

Same here. Also have a problem where, when on a call, an incoming call will kill bluetooth. This makes it unusable in my car as it becomes a real safety issue. I have to turn off BT and use the speakerphone which luckily is good enough for the job. Even switching the source and switching back doesn't always work for me.
I regret not sending the phone back for this problem. I'm waiting on v5.1 this month as rumored, hoping that will solve the problem. May just go back to my Lumina 925.
Has anyone tried going into Google settings app -> Search & Now -> Voice and turn on Bluetooth Headset (records audion through bluetooth headset if available).
I have Nexus 5 and Jabra Stealth and I had the same problem. I could solve it thanks to these indications: hackerspace.kinja.com/reassign-your-bluetooth-phone-button-to-open-google-n-1507391132
Same issue with calls not having audio through the car Bluetooth unless I switch to speaker/handset then back. I guess Marshmellow really messed up Bluetooth on a lot of people's phones not just us. Tried different rooms(AOSP, CM, stock) no help even tried updating the radio which helped Bluetooth crashing completely and requiring a restart but the phone issues remain.

Bluethooth Headset Issues

Love the Note 8 and everything about it except how it interacts with bluetooth headsets. I troubleshooted starting with a few bluetooth devices LG HBS1100, Samsung Flex, Motorola earpiece and car audio bluetooth. Here are a few things I encountered:
1. None of answer call buttons on the headsets will answer calls, even the Samsung Flex does not function properly
2. If you using an internet driven app such as Skype, WhatsApp etc, it is the worse. In addition to the buttons not working properly
A. The call waiting feature does not work when using internet audio or video it disconnects those call and allow the other call to come through sometimes unprompted.
B. If you are using Skype, WhatsApp etc, sometimes the call suddenly drops, battery still medium to full on the headsets.
C. A and B only happens with bluetooth headsets, call waiting function as design with car bluetooth calls and traditional BT earpieces
Im am posting this because a phone with this price tags should have overcome these discrepancies , the company should have come across this somehow during testing hmmm. It was almost a deal breaker but I like having a stylus, beautiful screen , phone design and the note taking features. I have friends that I communicate with overseas but I don't call them everyday or I will just use the speaker phone when Im talking to them.
I came from a 7 plus and all features on the BT headsets worked (Not enough to sway me back to Apple but its just confirmation.)
Has anyone experience these and what was the remedy if there was one Thanks..... or dead I get sent a lemon?
Never owned a Bluethooth. ?
Sent from my Galaxy Note8 using XDA Labs
Have been using 2 bluetooth headsets and a Gear S2 watch to answer calls, have been able to make and take calls without a fuss, although I've always used the phone itself or the watch to answer a call. Never used call waiting. I use Viber as well to receive calls and never had a problem and no drops.
I had some odd issues when connected to my Car Blue tooth - I was using Hotspot on my phone to connect my Car's Android Navigation system - listening to I Heart Radio in the car - made a call - call connected - but several times during the call - Blue tooth suddenly disconnected for about 10 seconds and then reconnected.
This happened several times on different calls. I don't know if using WIFI while I was connected to blue tooth had anything to do with this - and I don't have the note any more (I returned it because it was OEM Locked ) should have an unlocked version next week and I will try again. But I saw your post and thought I would share.
My Senheiser MB pro 2 works fine with the Note 8. If there is any tests you want me to perform let me know.
Only thing I noticed today was that if I went out of range, the headset and phone would not auto reconnect when in range again , not sure if this is normal or not.
I have a Plantronic Edge. When I'm on Duo it starts the video call fine and after a few seconds it disconnects and goes to the speaker. So far it only does this in that app or at least that I can tell.
Issue with me is I don't recall how the behavior of my Bluetooth headset was on my other previous phone's, like I mentioned it disconnected when I was out of range then didn't reconnect automatically. Should it reconnect automatically?

Help with bluetooth for calls

I am having a problem getting bluetooth to work with calls. When I pair with a BT device, it will often only connect for audio but not calls. I can go into the bt device settings and tap the Calls switch to turn it on but it will immediately turn right back off. This is happening on two devices that previously had no trouble connecting for calls. If I unpair the bt device then pair again, calls will work for a little while but then the calls option turns off and I have to unpair the device to get it to work again. Very very annoying.
Any idea why this is happening?

i had that same problem on my A8 for a while and out of the blue one day it just stopped doing that and it worked properly ever since that day. I didnt do anything to remedy it, it just stopped effing up on its own somehow. No OTA update or anything like that either. The exact same bt headphones (Tozo 10L's) have worked seamlessly on my S9 since the day i got it. Matter of fact, i never even had to pair them as the info carried over from my A8
