BT Connectivity in Car - T-Mobile Samsung Galaxy S II SGH-T989

While others Android devices I use seem to connect (and stay connected just fine), my GS2 T989 will connect to my VW's bluetooth system but, generally, disconnectes after 10-15 minutes. My Bionic stays connected until I release it.
Any settings I need to change?

Mine would do this while the connection tried to use the internet proxying. I have Toyota Entune. However, after this last update, the bluetooth has been rock solid. I'm guessing the driver update fixed a bug. I would do the update if you're on stock.

BT Toyota Problems
I am on Darkside Evolution 2B3 (Beta 03) and love this ROM, my only issue is that occasionally my BT connection will pause and unless I cycle through modes on the Car it will freeze. It works fine on my wife's toyota (Camry) but it locks up in mine. Does anyone else have this issue?

Mine has not done this with my Jawbone Icon, Motorola S10-HD stereo headphones or my Volkswagen Tiguan. Perhaps you might try another bluetooth device?
buletooth issue?
I had try different device and do the same thing, like my audi q7 and jarba headset and the garmin. Can you tell me what buletooth setting you are using?
Mine has intermittent issues as well, I'm using an older Motorola 710 BT earpiece. I'll only turn on BT on the phone when I know I'm going to use the earpiece, such as when driving or needing to be hands-free. I only activate the earpiece after enabling BT on the phone, but there are times when the earpiece does not connect.... the only fix is to reboot the phone. Is that similar to the issue you are having?
I'm having issues connecting to my car. If I reboot the phone and connect it will work. But once it's disconnected and I turn bluetooth off and then back on from the phone, it will not connect. Only way to fix it is to reboot. Don't know how to fix the issue. Never had a problem connecting my Sensation to my car's bluetooth.
My issue is similar in turning bluetooth on and off via the power widget and not being able to re-connect to my bluetooth earpiece after a few cycles. I'm wondering if it may be an issue with it being BT 2.0 versus BT 3.0 on the phone?
I thought it was my car but a lot ppl is having this issue too.
Sometimes it wont connect but it says connected so i have to go to BT settings and click where it says connected n overwrite the connection for it to work if not gotta restart the phone. :/
Tmo Galaxy S2
I'm having problems with a SoundFly FM Transmitter in my car.
At first it took forever to pair. And even when paired & connected it's really glitchy.
I'm using this mainly for GPS turn by turn over the car sound system. But because it is glitchy I can't use it because some of the directions get cut off.
I had a MyTouch 4G before. No problems whatsoever. I don't if it's a hardware or driver or BT device issue.
I'm willing to get a new FM Transmitter but not if it does the same thing.
It didn't work well on stock or rooted w/ Juggernaut rom
this is quite annoying. I wonder why this topic died so quickly, there have to be more people with this problem? Maybe has something to do with a bluetooth power saving sleep feature? Streaming music, pause music for a few minutes, incoming call gets connected but I get no sound through headset.

Bluetooth in Vehicle

I never had this issue with my 2010 VW Jetta when paired with my Droid Bionic - But every time my GS2 is connected, it remains connected for about 5 minutes, at most, and disconnects - It NEVER stays connected, paired, but not connected, and I need to reconnect. any ideas of how to keep this thing connected? Is it the "car's fault"?
What ROM you using?

Has it always performed this way with that car, or did it just start recently?

Bluetooth goes in and out

Got my AT&T Galaxy Note II. Have left the ROM, bootloader, etc. all stock.
Where my Galaxy Nexus would have trouble uploading my phonebook to my 2012 Honda CR-V car stereo without Navigation system, the Note II seems to pair without issue.
HOWEVER, if the phone is unplugged from power... about once every two minutes it drops the BT connection from the car stereo, and about 20 seconds later reconnects. I say if unplugged, because if I plug the phone into a cigarette lighter charger, the BT seems to stay up and stable.
I figure this could be a BT timeout issue, or perhaps some power setting we could adjust? I have disabled the power management functions on the Note 2, but that has not prevented the issue from occurring.
I also have a Sony SmartWatch that I have paired to the phone. The watch doesn't have any issues, but whether I have the watch on or off, I see the same functionality between the phone and the stock car deck.
I'm having the exact same problem, I thought it was an issue with my vehicle's Bluetooth antenna.
I tried calling Samsung about this issue and they were, as expected, pretty unhelpful.
I'm having a similar problem with my Ford Sync Bluetooth connection. Except I'm only using battery power.. The first time I connect for the day, all seems fine. Any subsequent connections during that day are problematic with connect failures or random disconnections.. Must be a gnote2 bug as my gnote1 (stock ROM) worked perfectly in my car.
As soon as I read this, I began to wonder if my issue is somehow related.

same problem here with SGN2 and Veloster...I lose my connection after a few minutes. Before with my HTC, I had no problem .
BT works fine for me in my MDX stereo and on my BlueAnt device. I don't have to plug it in or anything... just turn it on, pair it and go.
My note 2 is bone stock - just rooted so I can use Titanium Backup.

OTA May 2018 Update + Car Bluetooth Music issues

Hi all,
Has anyone experienced any weird Bluetooth issues after installing the latest May OTA update (OPM1.171019.011-RZR-180509.5038)? I've realized that the BT controls on my 2015 Nissan Sentra no longer work properly. It doesn't automatically connect to BT anymore and no track information shows on the head-unit. The weird thing is that I CAN get music to play, at least.
I just wanted to know if I happened to be losing my mind after numerous reboots and re-pairing between the car and the phone.
Same for me. I can delete it. Pair it again and it works. Next time I get in the car it won't reconnect.. worked fine before the update at the weekend.

It's a fire an miss actually. Sometimes it reconnects automatically with the car's unit (alpine aftermarket) and sometimes it doesn't. I had noticed that if I get in the car for the 1st time today (for ex), it won't reconnect back and i have to cycle around the input in order to "kickstart" the reconnecting process. If I make a stop along the way, stop the car, get out (thus interrupting the connection) and getting back after a while, it will reconnect automatically without any issues. I'm not even taking it out of my pocket. But this scenario is happening since day one, not necessarily from the last update.
On the other hand, I got a smartband (coincidentally after the last update) and now, while the smartband is connected via BT, when I turn on my BT wireless headphone adapter, it won't re-connect anymore (simultaneously with the smartband) and if it does, it's without media playback. As a workaround, I have to 1st turn off the smartband, clear the BT of any active connection (And also any other device with media playback capabilities), turn on the BT adapter so it will connect full, then turn the smartband back on. And not always works like this.
So, I do have on an off issues with the BT stability and connections with various devices, not just car unit.
Strangely though my smart watch connects no problem and the stereo in my motorhome was connecting at the weekend. It's just the car ( a Vauxhall Astra) that refuses to connect unless I delete and re pair....

I can't get music to play with Spotify or YouTube. The phone connects fine, shows song info but just won't play no matter what I try.
The weird thing is that calls work perfectly. Sound through car speakers and mic works. Just doesn't want to play music.
I've tried unpairing, re-pairing, deleting, even factory reset on both phone and stereo. Worked fine before the 8.1 Oreo update. (I'm on 3 UK handset).
Im having issues as well, it will connect the first time when I manually connect the phone and stereo to MyLink. It will say connected but (No Media) so i try to pair the media and it disconnects my phone from BT and then i have to delete device and re connect device manually. As well if i leave the vehicle or turn it off then it will disconnect. Not just my vehicle but the other showroom vehicles do that as well. Can someone let me know if there is a bluetooth upgrade or a firmware upgrade that can fix this problem? is there anything that we can do for this let me know. Thanks!!
I am having the same issue in my bmw.
I can delete the phone and re-pair... But it sucks having to do that every thing.
also having issues as well. It connects to my headphones and the after market HU in my truck but it will not connect at all to the factory HU in Genesis Coupe. I have tried to delete and re pair and still nothing.
So currently it all works for me with the latest update. It definitely takes a little bit longer than normal though. Not sure how long some of you waited, but compared to my old phones it feels like an eternity during the time it doesn't connect. I also use a smartwatch and it is always connected to that. If you guys need or want any files, let me know. I'm currently waiting for a usb-c to usb-a cable in the mail, so once that is here I can try to help.
I think this is all more of an Android issue. I was having most of the exact same issues mentioned here on my LG V20 on Oreo.
I just for a Razer Phone 1 off eBay this week. I did the Pie update and within a day, the bluetooth issues have returned. Sometimes phone won't connect to car stereo - sometimes reboot stereo, sometimes toggle phone bluetooth off/on, or sometimes just wait 10-30 seconds. Doing the same showing info on car stereo display, but no audio transmitted. I also had similar issues using a OnePlus 3 with both Dirty Unicorns and Resurrection Remix Pie ROMs. I was beginning to think it was my car stereo until I read the comments on this thread. Seeing so many others having the exact same issues on factory and aftermarket stereos (mine is an aftermarket), and knowing it's happening on different devices and both Oreo and Pie , I'm thinking it's an Android 8 and 9 issue.

Question Phone connection to car Bluetooth

Pixel 6 Pro does not stay connected to the car Bluetooth. 2018 Tacoma. Audio works but the phones keeps cutting out or off. It will disconnect from the radio.
I just paired my P^P to my MB, no drops, works great.
Toyota needs to be upgraded.
Mine is working fine on 2020 Toyota RAV4.
I have to manually connect to my head unit with the 6 pro (use a tasker shortcut to speed it up). Weird. All of my prior phones connected automatically.
Don't have any issues with my watch or pixel buds autoconnecting.
Mine is working fine. Lexus NX300h. Also Android Auto (wired) works fine.
Also working on my Benz SLK 300.
No issue with mine on a few different VWs I've been driving. Also android auto is working fine both wired and wireless, although I have to turn off my adguard VPN to get it to work wirelessly so I tend not to use that.
i am having the same issue in my 2007 tundra my op7p worked perfectly but the p6p is terrible, it will disconnect and get choppy for about a minute then it works perfectly until i turn the truck off then it happens again at next connection. very very aggravating
The bluetooth on my Pixel 6 Pro has been working great with the aftermarket android radio in my F150. I use it with Tasker to fire up the WiFi hotspot so I can listen to Spotify while I drive and haven't had any problems.
My wife was having this issue where the Bluetooth would disconnect after a minute on a phone call with her highlander. Someone else had mentioned that they noticed theirs would only disconnect when the screen was off. I told my wife to plug in her phone so the screen stays on, and it no longer disconnects. I never had the issue on my Camry, but my screen is generally on if I'm on the phone.
Edit: also turn on the A2DP hardware offload in developer settings if you haven't already.

I was seeing this also. It was working for a while and then at some point would just randomly disconnect. I'm using a completely custom IVI based on Dragonboard 820c and Automotive Mezzanine; https://www.aprax.tk/auto/ which is, coincidentally, also in a Tacoma.
I have NOT seen it lately though, likely since the January update. I'm running the January 14th release of Graphene; https://grapheneos.org/releases#stable-channel
