Severe Bluetooth issues - T-Mobile Samsung Galaxy S II SGH-T989

Hey guys,
I'm having some pretty bad bluetooth issues, and my searches haven't really found a solution. When I attempt to connect my phone to my car headunit, my headunit shows it's connected and my phone also shows connected. But the audio still comes out of the phone speaker. After a few minutes it will disconnect and reconnect a few times, sometimes only showing headset connected and not media. Eventually the bluetooth just locks up saying "connecting...". If I turn off bluetooth on my phone, the stereo still shows it is connected to a bluetooth device. I tried to "forget" my device and re-paired, and the process seems fine except the phone never asks if I want to share my phonebook, so I assume something behind the scenes is already broken at that point.
This is a very new problem for me, and my bluetooth was working fine with this headunit for months now using numerous different ROMs from GB to JB. I was on AOKP JB build 1 when this started. I tried a full wipe and reflashed the ROM and still had the problem. I have tested this on about five other ICS and JB ROMs and am currently on CM9.1 and the problem is continuing. I also tried a different phone to make sure the problem wasn't my headunit and the other phone worked as expected.
Has anyone else had this problem, or does anyone have any direction for me to fix this? Thanks!

I have a similar problem with aokp jb, when it wasn't present before. The head unit shows my phone audio connects but the media audio does not connect sometimes. I would have to reboot my phone or fully disconnect my phone from the head unit and pair them again.. no real solution but it is slight work around and to say that you're not alone

Thanks. I've had to reboot or re-pair in the past every once in awhile, but neither rebooting or re-pairing is fixing the connection anymore. Anyone else had this problem? Are know if there is some sort of log I can find on my phone that might give some clues to why this is happening?

Problem Solved....
I tried my phone in a different vehicle, with a different headunit. No problems at all. I went through my head unit menus and found an option to clear all bluetooth data. I assume this clears all paired device information from the headunit. Everything works perfect now. Phone pairs fast, stays connected, and all functions are perfect. I hope this helps someone at some point.

[Q] CM7 and Tunelink isn't working.

So a friend of mine bought me a TuneLink (for Android) for my birthday. I've been running CM7 Nightlies for quite a long time, and I'm currently using N93. The tunelink is great for the car, if it worked.
I've worked back and forth with support from NewPotato, the makers of the tunelink, and they are stumped. They have sent me multiple devices, thinking it was maybe a hardware issue, but nothing seems to work. At first, the device will pair and connect, and music will start playing, but after about 10 minutes, my phone becomes very slow and will eventually reboot itself. After this, the phone will connect but not pair to the tunelink. No matter what I do after the reboot, the phone refuses its connection.
I also have a Jabra Clipper that works perfectly all the time, without problems, and I haven't seen anyone else complain about the CM7 Bluetooth stack.
Anyone else witnessing any problems with any bluetooth device while running CM7?

Using 7.1-RC1 on an Incredible:
Also having issues with the TuneLink. Worked perfectly on stock ROM, when I switched to CM7 the device will work for about 5 minutes before the BT signal fades out and then I pick up nothing but interference when I play audio. Eventually the device just disconnects from the phone. Then the Bluetooth radio will not reconnect unless I pull the device and then let it sit for awhile.
This is a deal-breaking issue for me now that my iPod Touch is broken. I have to be able to listen to my podcasts in the car. I really don't want to go back to stock.
I should also add that my Bluetooth headphones work just fine with CM7.

no bluetooth calls

Hi
i was wondering if anyone else has had this problem. Two months ago my bluetooth was working fine with my parrott system in the car, but all of a sudden i cannot make any calls with bluetooth though the system, i have tested the parrott system using my sgt and my wifes wildfire s with no problems.
I was suspecting my current rom was causing the problems, but after using 3 different roms, and change the radios / ril a number of times im still unable to make any bluetooth calls.
Im now suspecting i may have an hardware failure but i really dont want to return it to stock then back to htc, does anyone have any ideas what else i could try before i take the plunge?
many thanks.
Are you pairing the devices OK? Set the permissions etc for auto connect?

yep. ive done everything i can think of now, ive even cleared of the pair on both devices and still having no luck. the machine connects fine - it shows the signal strength and battery level fine on my car stereo head unit (parrott), and auto connects with no problems
i managed to make my sgt ring earlier but as soon as it was picked up it was silent then the call was dropped after about 10 seconds.
ive got to try some other bluetooth devices now, i tried it on my samsung home cinema and it streams music fine but the thing i want it for fails.
thanks

[Q] Bluetooth pairing problem

Hi everyone!
I have a strange issue with bluetooth pairing between my Nitro and BlueAnt S1 in my car. Phone doesn't see bluetooth device. The only devices that it finds - it's phones. Does anyone else have a problem with the discovery of a media devices?
So far I haven't had this problem. Mine pairs with my truck for phone or media.

I'm not sure how it was before unbricking, but afterward I cannot start a call with the bluetooth enabled and a device paired.
It was my fault. I found the problem. Memory in car kit device was full, I made reset and phone found and paired to car kit device immediatly.
Well, interesting. I just tried pair phone to a laptop, the phone and laptop showed different auth codes.
After few unsuccessful tries pair from laptop and from phone itself the phone decided to crash and rebooted itself straight to boot animation bypassing the two lg logos. After that it was acting sluggish and I disabled bluetooth and rebooted it.
Then I installed different BT driver on laptop and tried pairing them again, with exact same result. With no phone reboot I left BT enabled and after an hour or so I received a notification message that internal memory is getting low. Opened applications list, nothing out of ordinary, so I rebooted the phone, now it stuck at boot animation, except it's not looping, the animation did just once. I can access phone with adb but no root and can't even list anything besides the / directory, everything else is denied.
BT is f.up?
P.S.
running unbricked 10i
Definitely some oddities epithet this phone. Personally hoping that cm9 will clear most of this up!
I'm on 10i as well. I haven't been able to make a call once with bluetooth. Never tried before I had to unbrick.

After hard reset the BT worked fine, so I suspect it's due to some bloatware freeze I did in the past.
Bluetooth issues as well
I also cannot make successful calls with Bluetooth enabled after I rooted this phone.
- I rooted the Phone.
- I did a full factory reset
Everything works fine until I pair a Bluetooth headset to my device, then everything slows to a crawl and becomes unresponsive.
It takes 3 mins for the phone launcher to pop up when I hit a speed dial to call some one.
Please help. is there a fix for the bluetooth pairing issue?
I actually make phone calls on my phone and I like handsfree when I am driving.
Any Help would be greatly appreciated.....

hey,
was there any solution for the bluetooth headset issue here. really need some help. thanks. pm me if you can please as i don't regularly check nitro threads.

Bluetooth connections problems.

Has anyone encountered issues with connecting with a car bluetooth? My wife phone conntects with no issues.. She can use the cars remotes to make and receive calls.. Mine I have to pick a contact from the phone for it to work, it will not work with the car or my work truck controls.. It seems everytime it ask if my car or truck can access my contacts, I always choose allow, but nothing happens, but it works with the wifes.. This is with the Lollipop update, that we both have...
happened to me I just rebooted my phone and it connected, also check settings for that paired device

Got one to work, in my truck.. The car it worked for a while, then quit.. I will try it agian to see if it will stcik... Most likely caused by the 5.0 update..
I've noticed a Bluetooth problem that suddenly started in the last week or so. I upgraded to Lollipop when it first hit, and didn't have any problems.
Now, however, after Bluetooth works fine for awhile (I can connect to a Pebble watch, Bluetooth speaker, car Bluetooth, etc) all day long - then all of a sudden it can't connect to ANYTHING. Toggling Bluetooth off\on doesn't fix it.
Restart the phone, then everything works just fine for awhile. Until it doesn't, and I have to restart again.
Anyone else experiencing this pattern?
I've actually had the opposite happen. I have a iSimple bluetooth box in my car. I've never been able to auto connect with either VZW Note2 or 4. The CS rep told me it had to do only with VZW phones and he couldn't help me out. On another forum, another member mentioned he didn't have any issues with his older phone, so I dug out my old HTC Incredible. Sure enough, it would auto connect. Something changed with Lollipop, and now my Note4 will finally auto connect to the iSimple box. I tried using a third party Bluetooth app prior, but it didn't fix the problem.
Finally got the one in the car working as well... Because the wife and I have the same phone, I just simply changed the name of my phone and it works fine..
If your talking about the developer edition one rom update.. YES.. What fixed mine was wiping everything and redoing the one rom lollipop, then twrp, then installing Ricks Rom Lollipop, things have been perfect. I even addressed it in the ricks rom thread the week.
I haven't had any issues connecting devices but since Lollipop, when I am connected to a bluetooth speaker (car, bose, other bluetooth speakers) the audio gets choppy randomly.
I have done some searching and found others (LG g3) who had the exact same issue after updating to Lollipop.
I have tried rebooting, using different music apps, unpairing/pairing, forgetting the device ect and nothing seems to work. Anyone else having this problem after updating to lollipop? Anyone know how to fix it?

Bluetooth Car Sync Issue

Is anyone else having issues syncing to your car? Mine connects for 5 seconds and then flashes phone not detected on my phone screen and disconnects. I am running the deluxe standard model, not the special edition. I have checked the easy stuff like making sure Bluetooth is enabled and successful pairing. I can connect to Bluetooth speakers no problem. My Google music app also froze and could not be recovered by powering off or closing apps. I had to uninstall and reinstall. Let me know if anyone has had a similar issue and hire or if you fixed it.
I listen to music in my car via A2DP/BT Audio & have no issues with either listening, or controlling (fwd, rewind, etc...) music apps like VLC via the car controls.
no problem pairing with my car, mobile, music etc etc.

2 ppl confirmed properly working BT;
1: make sure you're on the latest firmware
2: close any other apps which might be using BT (do you have other BT devices on you? They might be conflicting)
3: make sure your music app is whitelisted in battery optimization options
4: try other music apps, like VLC
5: choose balanced power management
6: factory reset & try BT audio as the 1st thing after a fresh boot; this should help you isolate the issue.

I have the same issue sometimes. My Honda Accord had no issues pairing to my Note 7, and connected to it perfectly every time. The car also initially paired quickly to the ZF3D, but when I get in the car I have to manually select the car in the Bluetooth menu. If I try waiting, it will either never connect, or flash like yours. connect for a second then lose connection.
either way, manually selecting it makes the phone keep its connection throughout the entire drive.
Hope it helps!

Thanks all, I tried all of the tips above to no effect. Manually selecting still drops within 5 seconds. Tonight I will try it in a different car to rule out a compatibility issue with mine. I aIso downloaded VLC and made sure everything was white listed. Phone reset had the same issue with no apps installed. My old Note 4 pairs just fine and stays connected. The Buick Bluetooth (2012) system isn't the most up to date either and has limited capability (phone only, no music) so it may be a car issue.
Thanks,
Eric

It is a car compatibility issue. It works fine in other cars apparently just not older Buicks. Thanks for the assistance everyone.

I was never able to pair it with my vehicle even after a reset. It works fine with my other car, and it works fine with everything else I have tried.

I am finding that auto connecting to BT in the car and on my Gear S3 is hit and miss, however i have had no issues when doing it manually, but it is a pain in the ass. hopefully ASUS will fix this when they release the nougat update!
My Zenfone 3 will pair with the car and a number comes up that I have to type into the phone but the keypad flashes up on the phone for 1 second and then disappears too quickly to enter it. I have tryed it about 10 times and always the same result. Anyone have any idears on how to fix it.
