[Q] Bluetooth issues - Galaxy S II Q&A, Help & Troubleshooting

Hi,
I have the following problem:
Everytime I pair my Samsung Galaxy SII I9000 with my car (Renault Fluence 2012) and its built in bluetooth System, it says that it's correctly paired (and honestly it doesnt even take a minute to pair correctly), but it plays no music. It just has no sound (even when the song is playing correctly on the phone) but everything else just works perfect. I mean, i can control the music (songs, playlists, etc) from my car, but the sound just wont come out. The only way to make it work is to 'unlock' the sound by calling someone. So when the call starts, then the audio starts working. That is, so far, the only way to make it work. And i have to do it EVERY SINGLE TIME that i turn on the car or that the device stops being paired with my car.
It does EXACTLY the same thing with my bluetooth headphones (Motorola S305), so I realized it was my phone. I have tried other phones with my car and they work just fine. I have tried other things with my headphones too (like my Psvita) and they work smoothly.
The weird thing about it, is that my phone used to work perfectly fine with both things, and just a random day it decided not to work anymore.
I used kies and re-installed android from 0, and that solved the problem for a few days and then it all started again. I have tried cleaning all the bluetooth devices that my phone is paired with. Going back to factory settings in my car, removing the battery on the phone, resetting the phone, taking everything out (including the sim card( everything. And nothing seems to work.
Please, help!
My phone is a Samsung Galaxy SII with Android 2.3.6 (it came with 2.3.3 and i upgrade it twice through kies) I have never rooted my phone or done anything to it, except for upgrading Android through Kies.
Thanks so much!!!

Wow... That's very strange. First off, I'd be looking at compatibility issues. Do you have the BT specs for the car? Maybe they're the same as the headset and not quite 100% compatible with the phone.
Another possibility (although remote) is that the headset and the car are fighting over which gets to talk to your phone because phone services are much different than A2DP (Audio).
You might just have a flaky BT antenna in your device, or a bad (stock) modem/baseband.
I'd try rooting and see if a different modem/baseband clears up the issue. Then at least you'll know what the deal is.
Hey, I also found this on the Renault web site... http://www.renault.co.uk/bluetooth/default.aspx
>> Why does my telephone not reconnect to the system when the vehicle is started?
- In order for your telephone to automatically connect when the vehicle is started, it may be necessary to activate the automatic Bluetooth connection function on your telephone with the hands-free kit. For details on how to do this, please refer to the instructions manual for your telephone.
- Upon reconnection and if there are several telephones paired within the hands-free kit reception area, it is the one that was paired last that will be connected even if it is outside of the vehicle.
So it looks like it might actually be a Renault AND a Motorola problem.
There's also a list of compatibility files at the bottom of that page based on the system you have.

First of all, thanks so much for your help.
The problem with whats going on with my phone, is that it used to work just fine before, with those 2 things (my car and my headphones) Its not like they never worked, they used to work completely fine with my phone.
And i never use them together, like my headphones have never even come close to my car. And since i thought that it could have been a problem with they 'fighting' with each other, even if they werent close, i erased all the cache on my bluetooth settings and unpaired all devices that were ever set with my phone.
So its like if i had never used bluetooth. That obviously didnt work either

It turns out that your car likely keeps up to 5 phones in memory... Is there a way to clear the phone list in the car as well? Then re-pair from scratch on both sides?

well either the blueth is defect or ur doing some wrong settings,root ur device there r plenty of bt apps tht work more powerfull than the default...y possible ur car mus hav a reset buttun for bt so delete all pairs frm phone an reset ur car bt,,,,then start fresh.....hope it helps

I restored my car's settings and deleted every phone paired. That didnt work either... I also tried with a friends phone (iphone 4) and that worked completely fine...

Time for a warranty replacement I think.

Jeez... thats exactly what i was trying to avoid, because my cellphone company will have me waiting for like a month without my phone and will give me in return the ****tiest phone ever while they try to fix it and then realize they cant.

thanks anyway for your help!

Vibrant - Bluetooth connectivity issues?

Anyone ever have connectivity/inconsistent connectivity with Bluetooth on the Vibrant?
I never use it, but another XDA user mentioned they were having issues.
If you have had issues, what suggestions can you make?
The only connection problem I have ever experienced is sometimes with my phone, it will connect --- disconnect ---then connect when I first turn on my car (Infiniti m35) but it does that all in a matter of 5-7 seconds then it never has issues after that. Bluetooth is remarkable on this phone....... wish the GPS was as good. Running latest Bi-winning now
Me and my wife have both had the same issue with a paired device not connecting and you have to turn Bluetooth off and then back on and all is well. Doesn't happen often but can be a little annoying when it does. By the way my wife's vibrant is completely stock and I'm on cm7.

I use Jawbone Era and it randomly disconnects even when phone is in my pocket and bluetooth in ear. It reconnects a few times but mostly I have to turn the headset off/on to reconnect. Froyo 2.2.1 is better with Bluetooth than 2.2.0
It might be the headset though, our phonen is one of the FEW devices that has Bluetooth 3.0
Even the new LG G2X has 2.1 and not 3.0
I use bluetooth headset regularly on bionix 1.3.1. No disconnections, but the signal strength seems week as there is lot of distortion if the phone is in my pocket. So I have to always hold phone in my hand.

The issues I have (no matter what ROM I use) are Connect - Disconnect - Connect and then the stack is hosed. Have to reboot the machine to get Bluetooth to reconnect (Using Motorola H117). Also, can't figure out the exact pattern, but if I get a notification while bluetooth is on I turn it off and no more notification sounds... or ringing... or anything. I have to reboot to get sounds back.
I connect to my car stereo and sometimes I hear skipping. With my plantronics headset sometimes the signal gets weak if the phone is in my pocket
Sent from Glensta's phone
It is a weak signal in the phone. I have had several phone over the years and my old nokia flip phone was the only one that could do more then 3 feet without issues. My HTC kieser, HTC Shadow, N1 and my current SGS all have issues with my BT headset if the phone is in my pocket on the opposite side of my body from the headset. My old Nokia would let me use the same headset a room away so go figure.
One thing I have noticed is I if I try and transfere a file to any phone(other then the nokia) the file transfere always fails. It works to and from a PC but not to another phone of any kind(except the nokia).... very odd.
my bluetooth has been inconsistantly connecting since I started using 2.2.1 ROMs. it always worked fine previous to that on all the 2.2 ROMs I used.

After turning bluetooth off on my phone or turning off my headset once or twice I frequently lose all sounds as well. Glad i'm not the only one.
I have the problem of sound not switching back to the speaker if I turn off either the headset or Bluetooth on the device.
How does Samsung screw something as simple as this up and it not be fixed after 4 official updates?
Nothing about Samsung's top notch screen is worth dealing with the headaches that come with their software. I'm trying to wait for the second generation dual core devices but, if I see good reviews on the Sensation, I am jumping off the Samsung emotional rollercoaster.

I have been back and forth with Samsung over the past 6 days attempting to troubleshoot this.
I have used a Motorola H117 and a Rocket Fish Stereo Headset that I have used with the phone. The following *almost* replicates the sound system crash every time.
1. Turn on Bluetooth headset
2. Press button
3. Voice Dial a contact
4. Phone conversation for 25 - 30 minutes
5. Disconnect phone conversation
6. Bluetooth remains connected for another 20 - 30 minutes
7. Turn off Bluetooth headset... no more sounds from phone.
Nothing fixes it short of a reboot of the phone.
I am running STOCK 2.2 KB5 right now. Factory Reset, No root, on the 5th Phone replacement from T-Mobile. I have an open case with 2nd Level support with Samsung however they have given me every excuse from "It's your headset" to "We don't replace phones". I have not asked for a phone replacement and I am earnestly trying to troubleshoot this problem with them.
If anyone has any additional information, please add it to this thread. I have passed the URL for this thread on to Samsung (I do not know if they will bother with hitting it) but I am cross posting at the T-Mobile forums as well as publishing on Twitter.
My only issue is that I have to manually connect bluetooth every time I get in the car. I don't know if this is a problem with my phone or with the bt-fm transmitter our both. otherwise, once I'm connected, music plays great.

I have the same problem. I found an alternative to rebooting your phone to hear your sound again. Just play a visual voice mail message and hit the speakerphone button in the UI. Your sound will return. You can also play a google voicemail message and hit the speakerphone. It's not a fix but it will keep you rom rebooting your phone several times a day.
I use 2 Bluetooth devices on my phone.
Sony bluetooth headset:
Skips a lot, depending on what I have running. It's worse the more apps I have. To get the best performance, I usually need to end task everything that's running, clear all RAM, then run the music app again. I use the stock music app. I have had better performance out of several ROM's. I think it might be tied to the kernal used, depending on how much space is left (i.e. Bullet's 339mb kernal that I'm using with Simply Honey). Almost like there's a buffer issue.
Kenwood headunit:
I only use the bluetooth connection for handsfree while I'm driving. The only issue I've encountered is that the bluetooth connection is not always automatically restored everytime I get in my truck. If I go into Wireless and Network>Bluetooth, I can get the connection working again. It seems to always be a phone issue, not the headunit.
If you want a beta tester for something, let me know. I use both the headphones and headunit quite frequently.
We just got a '12 Honda Odyssey.
My Sensation works perfectly with the car's bluetooth but the wife's Vibrant is crap for connecting. Very disappointing. Came here hoping rooting her phone and installing CM7 would fix the problem, but that appears to not be the case.
Shame.
No more Samsung phones for us....
I use trigger 8/22 and the Bluetooth works better than ever. Stock gave me head aches

+1 for Vibrant bluetooth problems. I have a garmin nuvi in my car and sometimes it works, sometimes I get the connect-disconnect-connect, and sometimes it doesn't even try to connect.
I've tried stock, bionix 1.2, 1.3.1, and NextGen 2 and only bionix 1.2 seemed to work reliably.
When it works it is fine.
When it does the connect-disconnect-connect thing it sometimes works for phone calls be most often the audio is going through my handset even though the phone claims a BT connection has been made.
Finally in the case where the BT stack is so f'ed up that it doesn't even try to connect it seems like there's some serious battery drain that doesn't show up on the battery stats screen. I suspect the BT is stuck in some kind of loop that causes it to fail and burn lots of power.
The inconsistency is probably the most aggravating part of the whole thing...

Car telephone problem. Why won't it work? [FIXED I THINK BUT I STILL HAVE A QUESTION]

I can pair my phone with my car but 90% of the time I cannot hear the other caller and get a lot of distortion and hear myself echoing. The caller can hear me but not too well. A couple of times it worked ok. It seemed to work better when I had lite'ning rom installed, but due to an issue with car mode popping up randomly I have played around with various different roms. Now though my phone whilst pairing fine will just not work audio wise with my car. It is a 2010 BMW z4. BMW site lists the phone as compatible. I have searched high and low but the only problem I can find tends to be contacts not showing up etc. For me this is fine I just can't hear anyone when I make a call.
Is there something I can do with the phone to make it work? I found a root related bluetooth apk file remnaming thing but it didn't work.
Please help as this is driving (literally) me nuts.
Anyone got any ideas on this?
Ok, I investigated more. I have a program called Total Recall installed. It can be set to record all calls. On previous ROM's I think it occasionally crashed or got stopped when I closed stuff with task manager. On this ROM it seems to work constantly. This may be why my car Bluetooth used to work on occasions and not others.
I froze it with MyBackup Pro and voilĂ  my car worked properly with the phone.
So I guess my next question is does anyone know anything about this program and why it would mess up car Bluetooth? If I can't get it to work can anyone recommend an alternative?
EDIT: Seems I can set it not to try and record if BT connected. Shame as that would be useful.

[Q] Galaxy s2 restarts during bluetooth music streaming

I have just received a new S2 after breaking my old one. I need to know if this one needs to go back.
I stream all my music through my Sony car stereo via Bluetooth. Now since getting my new phone. After about 15 minutes of streaming my phone kind of restarts itself. I say kind of, as it doesn't ask for the sim password, but it does go back to the home screen with the music player completely shut down. I loose all BT connection between phone and stereo and I have to find the track i was previously listening to, as though i have opened the player for the first time that day.
When this happens I have no other apps running, and I know the music player has an auto switch off timer in its settings, but i have got this switched off.
I upgraded it to ICS straight away so never tested if this fault occurred whilst my new phone was on Gingerbread.
Is this an ICS fault or the phone? As I didn't get chance to upgrade to ICS before I broke my old phone. So cannot tell.
Hope someone can help.

Thanks. I have the timeout set to never. Also how do you unpair a device on my S2 ? I am running ICS.
I have tried holding for a number on seconds but no menu comes up. plus the lower left button brings up no menu that offers to unpair.
I'm confused!!!
I have the same problem!
The model of my sony bluetooth car radio is mex-bt5700
The problem began when I began to install ics roms.
The restart is always each 22-23 minutes.
I have tried andyx rom, wanam and others...and always the same.
I have also tried lot of apps, google music, samsung player, player pro, poweramp...
The problem is that I have also bluetooth headset (sony bt-101) and I have no restart with it.
Only with Sony radio.
Hope somebody founds a solution because is very anoying and I wish to stay with ics...I love it!
Thanks!
Well i've tried all but one thing now. Unpairing, repairing, spitting, swearing, apart from stamping on it my last thought is i'm restoring factory settings and trying back on Gingerbread. Just to ensure it is not my phone, and it is ICS.
Once i've done this and tested it i will report back.
Hi Pope, did you have any luck? I am having the same problem with my Galaxy SII. I've tried factory resets, removing the MicroSD card, re-pairing the bluetooth, nothing helps.
I called my provider and they suggested it could've been a bad cell in the battery (been fine with previous Galaxies), or cooking the phone by having navi, music and data on (again, been fine with previous Galaxies).
They're sending me another phone tomorrow, I'll see if it does the same.
Fu..k this is the worst problem i am facing too, dam it why all the **** happens with android and not the iphone, this is when i get teased by how fu..ked android is by my friends when this happens infront of them.
I am fuming now, as it also only happens with my sony car stereo and not with my bluetooth headset ( philips ). Dam Dam, so shall I go back to dam SLOW GB just to solve this grap.
And why exactly after 30 minutes this ****y reboot happens with my sony car stereo when playing music over bluetooth
I am so angry now, as I am sure not many suffer from that problem so no solution will fix that
And for gods sake which controls the sound coming out of the device via bluetooth is it the kernel or the modem, AAHHHHHHHHHHH i am about to throw this mother f___cker out the fu____king window
Galaxy SII bluetooth crash
I also have the Galaxy S2, and also the Bluetooth streaming reboot issue. Seems to have started after the ICS upgrade. Every couple of songs the the track starts to glitch and I know the crash is coming. From my research it seems to commonly affect people streaming to Sony in-car systems. Hope there is a fix soon...:/
I have the very same problem! It started when I updated to ICS and it only happens with my Sony car stereo. Any solutions?
i seem to have fixed my problem, took the sony MEX back and bought a Alpine bluetooth stereo, its ran for over an hour now without a reboot,
if you want to keep the same stereo you need to upgrade to a custom 4.0.4 rom
paranoid android also works. but you will need PlayerPro Music Player to stream track details to the head unit.

Bluetooth audio in car to phone not working

So, I'm having a strange issue with my new Note that I can't quite determine where the root cause may be, or if it's a known issue.
If I register my Note with my car as both a phone and an audio device (how the Infiniti nav/stereo works) I can use the Note as a phone fine UNLESS I start an audio app, such as Pandora. Once a2dp audio starts the Note will no longer connect as a phone device, but it works fine for audio.
I had the phone paired with the stock ATT rom but only used it as a phone, so unfortunately, without a restore to stock, I can't tell if the problem exists with the stock rom.
I flashed to flappjaxxx's rom (which I love) the same day I setup the phone to run Pandora via Bluetooth and that's when I started seeing the problem.
I also see some random connect/reconnects that seem a bit more than usual.
So, I can't say there's a correlation, or if this is a known ICS beta issue or what, but I'm hoping it is and that it's not a design flaw
Way I see it it's either:
1. Flashing to any ICS beta rom has the problem, currently?
2. It's in flappjaxxx's build (doubtful)
3. It's user error...(possible )
4. It's an app issue (ie. Pandora is causing the problem?)
Anyone have any thoughts, suggestions or insights? I've done some searching but haven't found this exact issue yet on any posts.
Thanks!
I have a Kenwood DNX9960 in my Avalanche. It connects also for phone and for streaming media. I can be streaming media from either the stock music player or an internet site like pandora or TuneIn and my calls will automatically come through. When the call ends it goes right back to streaming.
It autoconnects to both as long as my phone is in range when I turn on the kenwood. I did have an issue at first where it would not autoconnect. I deleted the pairing from both my phone and headunit. Then when I repaired I paid close attention to check any boxes to "Always" allow connection and I haven't had any issues since.
I understand the normal pairing process, I've had several phones before that worked fine prior to the Note. So, I'm thinking that it is probably a corrupt bluetooth db... I'm going to be reflashing to Flaps new rom and we'll see how that does
Is there a way to delete the pairing from the nav? I would try that
Sent from my SAMSUNG-SGH-I717 using xda premium
There is. I've tried it all, on both sides of the pairing.
I've reflashed the phone to the B6 from FJ, still no joy. The pairing db was new (so no chance of corruption on the phone) and the pairing deleted on the device.
It seems to be a problem with the phone switching between a2dp and phone bt. When a call comes in (while playing say Pandora over bt) the audio cuts out and then the car shows "disconnected" and then "connection failed" if trying to reconnect to the Note as a phone (ie hitting the phone button in the car).
I'm hoping it's the current ICS build. Just have no way to really know. Hoping some other folks will have seen the same issue.
Going to run some tests with different audio sources and see if the behavior is the same.
Well things seem to be working now, for no obvious reason I'll have to assume that the reflash resolved the issue, I just can't tell for sure why it didn't work immediately after. I think it's due to deleting the old pairing on the car and not shutting down the vehicle.
Cheers.
BT connections
I have similar problem connecting to van audio system (vauxhall). After some experimentation it appears to be an ICS problem, if I reflash my note with gingerbread I have seamless connections for both audio and phone. As soon as I upgrade even with offical ICS bluetooth connections become problematic, I can pair but not autoconnect. Tried samsung and they just "fob off" with it's an incompatable device. Until a bug fix is issued it appears as though it's a choic of staying with gingerbread and have a working system or ICS and no handsfree.

Phone calls via bluetooth (car and Jaybird X3)

EDIT: I just had this issue with a Jaybird X3 wireless earbuds. So it's not the BMW's issue. Any new ideas?
Hi! Wonder if anyone's encountered this issue and have any idea how to fix it.
Whenever I make or receive a phone call while in the car, the audio will ALWAYS come out of the phone's speaker instead of through the car's bluetooth. I can see the "in-call" screen on the phone and it says that output is BT. I have to push the BT icon to turn that off and on again and the audio will now go to the car. Every single time.
Tried un-pairing and pairing again, tried rebooting the phone. Nothing. Only does this with the car (BMW 3-series, 2017), all my other BT headsets and my wife's car work perfectly fine.
Any ideas?
P.S. I'm very aware that this may be BMW's fault, since they're dicks and suck at software development. Still, if anyone has an idea, it'd be very welcome!!
Hmm, I do not have this issue on my F32 and S9+ Snapdragon. Have you tried factory resetting the phone and iDrive to clear out any other pairings or non-default settings? It is a pain to set everything up again but will be the quickest way to determine if this is an issue with the iDrive. Next would be trying an iDrive update.
How do you reset iDrive? because I'm noticing that it's not syncing all the contacts on the phone... prefer this to doing a factory reset on the phone (paaaainful!)
Bumping because new information added
Haven't gotten any calls while using my Jaybird, but in my Corvette call audio comes through the car speakers, not the phone. Same in my wife's Honda.
Something to look at: When I'm connected to the car BT, there's a notification from Samsung's Smartthings app that I can tap and choose whether audio goes to the car, or to the phone. Might be worth checking that.
Unfortunately, it doesn't seem to remember your selection from one session to the next.
Hola
I use a X3 daily for both work and my workouts. When I drive to work or so I connect to my Toyota Highlander ('17) and thus far absolutely no issues with phone calls. Mind you I make A LOT of calls all the time so I would be peeved no hell if I had such issues. Like mentioned above, resetting your phone might be required. Please keep us informed if resetting does help. Thanks.
No issue with my BMW and I have jaybird as well but only uses it for songs
Well, crap. Will have to reset phone and report back.
Thanks everyone!
UPDATE: Factory reset worked!!!
My guess is that when I moved from the S7 to the S9+, I used the "Smart Switch" app. Something must have transferred over that the new phone didn't like. Took me 2+ hours and it is a pain in the ass, but now I can use my car's BT and the X3 earphones to make calls!
