[Q] Downgrade Bluetooth Software on AT&T S4? - AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin

Hello XDA!
So since I got my Galaxy S4 (NC1 build) I have not been able to use the Bluetooth with my car (ACURA TL 2006). Apparently Samsung has upgraded the Bluetooth so far that it is no longer backwards compatible. There are lots of threads about this on ACURA forums, I am sure other cars have the same issue.
Is there anyway that I could :downgrade" the built-in Bluetooth to a lower version so that it works with older devices? Any upgrade doesn't benefit me anyway.
Any help is appreciated!

Did your old phone connect using BT? I'd delete the old profile and start fresh with a new one.
Make sure BT is on and your phone is discoverable. I'd do the easy stuff before trying to downgrade any BT firmware/drivers.

Moved this thread to the Q&A section where it should have been posted originally. The desire to include the [Q] tag should have been your first hint about this

Thank you for your response.
Yes I removed all the profiles from the car (there were like 5 different ones). The car does not see the phone and vice versa. Of course BT is discoverable. There are many threads about this on ACURAZINE forums, both ACURA and Samsung refuse to help. I think its wrong that BT is not backwards compatible.

Thank you for your comment. I have UNFORTUNATELY taken the OTA and my S4 is now on NJ4. No change in Bluetooth thought. My ACURA TL still doesn't see the S4, neither does the S4 see the ACURA TL. (My 10 year old TMobile T610 worth $0.00 easily connects to car bluetooth). I say unfortunately because now I cant even SIM UNLOCK , my previous versions I guess up to MK2 could easily be unlocked with a couple of clicks.

[Q] Problems with bluetooth

Hi,
I'm havig a very strange problem with my Omnia 7: the bluetooth headsets transmit only noises and/or a "robotic" voice during a call. People on the other side simple can't understand a word a say, although I hear them perfectly. I already tried three different headsets (two bluetooth 2.0 and one older) and the problem is always the same.
Also I noticed that the phone does not find any bluetooth devices if it has wi-fi turned on!
Is anyone experiencing the same problems? Any thoughts on this subject would be very much appreciated. Thanks
Ricardo
I dont know for your problem but I am facing bluetooth issue too...
I am not able to connect it to my car kit (Parot) ... I never had any problem with my preivous phones (HTC HD2, Desire, ...)
I am having exactly the same problem - and have upgraded to official Mango version.. Buetooth Audio is just not working at all. Did you guys ever solve this?

I had same problem with mine , it wouldnt connect to my Parrot minislim car kit. It was sent abck to Samsubg in UK and they replaced the board and now all works fine. I knew the replaced the board because when i git it back it had only 8GB memory; had to send it back a second time to get it changed to 16GB version. So, get on to Samsung and have that board changed!!
Mango update has broken my bluetooth
Thought I'd add my woes to this thread.
On t-mobile uk, omnia 7.
Got bored waiting for official mango so unbranded the phone and updated. All worked fine.
However bluetooth now wont connect to my car! BMW. (will find other peoples bluetooth phones etc.) This was working fine before the update.
Is the bluetooth a product of the firmware revision which is now 2424.11.8.5
or something else?
Is there going to be samsung specific stuff come out? and how does one get it?
Or whould i go back to t-mobile build (anyone know where to get this?) and wait for official update??!
Cheers
Rob

[Q] LG G2 Handsfreelink issue

I just got my new LG G2 from Sprint and have been very excited about the upgrade. One thing that I noticed, however, is that the G2 is not supported by Handsfreelink, commonly used by Honda/Acura for bluetooth connection while driving. Please forgive me if this question has been posted already, but is there any work around to get the G2 to be recognized by my Acura? My old LG Optimus G paired up just find so I can't help but feel that there might be something in that stock rom that can be pulled and made available to flash in the G2 to trick the Handsfreelink software in the car to recognize the phone. TIA.
Update software in car.

Handsfreelink doesn't offer software updates. Acura will tell me that my car is outdated and that I need a new car (or stick with an old phone). Both choices I would rather avoid.

To my understanding, if you have a newer Honda/Acura you shouldn't have any problems pairing with some of the newer phones. The issue here is that my car is an 06 and my phone is from 2013 (hence the incompatibility). I'm hoping that someone has gutted the LG Optimus G (or Galaxy Nexus since that phone paired fine too) and has been able to pinpoint the code/script that allows the older phone to pair with my handsfreelink.

moto x 4.4.4 bluetooth - not fixed

For those anxious to get 4.4.4 you might try liquidsmooth which now incorporates it and runs on most if not all moto-x's. It's been upgraded to 4.4.4. Unfortunately, bluetooth is still not working correctly for me and if I try to pair the phone with my car, the car's system goes into a slow endless loop where the phone is connected and then disconnected. I am going to try to see if there is some way to get the phone working with my car....it's very frustrating because the moto-x has never connected correctly (galaxy nexus was flawless in this regard).
I am guessing that it isn't built on the 444 kernel, so, don't get too discouraged yet

What year make and model do you have? I have a 2011 Ford Edge and 2011 Ford Fusion, both of which use Ford Sync (Suck), and I have no issues with either.
Also, are you stock, or running a custom ROM? You seem to be running a custom ROM, and in that case, all bets are off.

It is 4.4.4 kernel. I think I've found the issue and it's unique to "techies". I have a pebble smart watch which uses google...the connection to the car system (2014 MB) uses bluetooth. If I don't wear my watch, the connection to the car works...no loops/etc. When I wear the watch in the car, the car/phone link goes all screwy. I suspect that one of the bluetooth stacks doesn't like to share....and I'd bet it's the moto-x stack which can either use the bluetooth or the car link, but not manage both together, even though everything is paired correctly. I haven't checked to see if pebble and the MB use the same protocols...it may be that they both share txt even though I only need phone on the car link.
I'll post more when I get further into this....I just stumbled on the cause today when I didn't wear the watch and repaired the phone with the 4.4.4 kernel.

I've heard them all, but we've had precisely zero issues with the Fusion, and one with the Edge that was fixed free of charge due to silent recall.
My only issue with Sync is that my Fusion has the Gen 1 version, and the most recent software update removed the key reason I chose this car over the then comparable Sonata. Without that feature, I would have gone with the Sonata.

[Q] Help with Bluetooth

Hi Guys,
i recently upgraded my S4 to a S5
My S4 connected to my car stereo as phone and as multimedia device, but my new s5 just wont connect as multimedia device.
It functions fine as telephone, but i cant get the multimedia option checked.
Is there some hidden option somewhere i'm missing ?.
I didn't have to do anything special for my S4 to connect as multimedia device.

Unfortunately you didn't give us any details of how you tried to pair your stereo to your phone. So we have nothing to work with, no way to point out a missed step or error.
Did you choose the appropriate pairing mode in your stereo menu? If you have continued difficulties, you should tell us what model your stereo is, your S5 firmware version and a detailed description of the steps you tried.

Unless your car stereo is A2DP compliant your phone wont use it for multimedia. Check that out.
This is driving me crazy.
I've spend a couple of hours now in the car trying everything i can think of.
A google search learned that I'm not the only one with this problem.
Clearing the Bluetooth cache didn't help, i installed this app but that didn't work also.
I popped my sim back into my old s4 and it connects perfectly as both phone and multimedia device, allowing me to play music from my phone on the car stereo system.
The car is a Toyota Prius 2012.
I've attached the specs of my new S5.
The S5 only connects as phone and not as multimedia device.
I also experienced BT trouble with S5 in my wife's Prius 2012. My iPhone connects with no problems, phone, multimedia, internet.
I tried to share S5's Internet but after asking/reading here found out that a vital file is missing, /system/bin/pand.
The reason why you don't get MM connection could be similar.

I copied a pand file (and the libbluetoothd.so) from a cyanogenmod image. it didn't help.
doing a logcat |grep bluetooth i noticed the following:
whenever i try to activate a mm connection from the phone to the car i get this line twice in the log file:
V/BluetoothEventManager(12390): Recieved android.bluetooth.a2dp.profile.action.CONNECTION_STATE_CHANGED
Since it's always twice, i think that it activates and immediately deactivates the a2dp connection to the car. looks like a programming error where you cant have 2 active bluetooth connections at the same time.
Hope they fix this really soon.
Not much help to you but I can get my UK S5 to connect fine to my factory car kit. I can connect for hands free, mp3 playback and as a modem for Internet all at once.

I contacted Toyota, there is an update available.
Going to the dealer on Friday, hope it fixes the problem.

You were able to share Internet via Bluetooth?
Yep. You have to enable tethering to get it to work with Command Online through.

Can you explain how in more detail?
Turn on the tethering option (search tethering in settings). Your car will connect to the phone for online access. This is how the 2013 model works.
I have the same problem with my S5 Duos. My Car is a Skoda Yeti. My Android Version is 5.0 Lollipop.
I also spent a couple of hours. Has anyone solved the problem.

S4 i9505 & BMW F30 - E-Mail

Hi All
Just got upgraded to an S4 i9505 for my work phone and I'm happy to have an Android device over the Blackberry I had before.
My phone is already rooted and setup to the way I like it.
The FEAR I had came true when pairing the phone with my car. I have a F30 BMW with extended Bluetooth option, which enables you to have like a mobile office on the iDrive.
With the Blackberry I was able to :
1. See all my Contacts
2. See my SMS/Text messages
3. Able to play music via Bluetooth
4. Able to read e-mails, both my exchange and gmail
With the Samsung S4 I can do all of the the above but can't read my e-mails anymore. This feature are very handy since I drive allot for work and having the iDrive option to read the e-mail back to you helps allot to keep up with whats going on at work.
Have searched via google, XDA and some BMW forums, but have not yet seen an option that works. It appears that it's an android issue with regards to MAP (Message Access Profile) not working the same way in Android as it does with Blackberry.
My phone is running KK 4.4.2 Stock ROM, my car has been updated to the latest Bluetooth software. Do anyone know of any third party App or xposed type framework solution to get the working?
Many thanks for any suggestions in advance.
Any help or suggestions?
