Question Bluetooth call dropouts in car - Samsung Galaxy S21 Ultra

Whenever I'm on a call while connected to my car the phone disconnects Bluetooth and routes the call back to the device,later it connects back to the car again. This keeps going on. Any idea why??

Could be caused by different things.
Maybe the bluetooth version of the phone and the car do not match.
Or there might be a kind of energy saving setting. Hard to say.
Best to test with other phones connecting to your car, and connecting your phone to other cars.

[Q] Auto connect A2DP

Is there an app for android to automatically connect A2DP when the handsfree connects?
I used to use an app called autoA2DP on win mobile.
At first pairing it connects both a2dp and handsfree, after that only handsfree connects automatically, any help would be appreciated as it's already driving me nuts....
Thanks!

Go to bluetooth settings, long press on the device in question, then options. Make sure Phone and Media are both checked.
Yep, they are... I can manually connect a2dp from both the car stereo and the phone, it just doesn't happen automatically like the handsfree does, had the same prob with windows mobile, but an xda dev user here developed autoA2DP to watch for a handsfree connection, then activate A2DP.
I don't know why yours is different, but mine auto connects for both every time I turn my Bluetooth headset on.
It does vary between headsets a bit. My Jabra Halo's connect automatically when I power on the phone or the headset. On the other hand my JBL Reference 610's had to be connected manually every time.
Still it seems odd though that is connects in handsfree and not A2DP, I always thought it was all or nothing. When a device connects it gives all available profiles and the phone decides what to accept. I don't know, sorry.
I have the same problem.. it does not auto connect with my car's bluetooth. The only way it auto connects is when I have the discoverable mode on (which has a limit of 116 secs or so). So an app that lets you be discoverable all the time would be great!

Same problem but reverse. My phone connects automatically to my phones music everytime i switch it on, however the more important headset/phone functions do not. I must manually disconnect and reconnect the stereo from within the phones bluetooth settings for both to work. Have looked through hundreds of threads found loads of people eith the same problem, yet no solutions. Would love an app to just disconnect and reconnect the bluetooth the moment it detects a paired device in range.... as yet found nothing...
Well... I'm getting the same.
I have LiquidAUX on my car and to have both phone and a2dp synced, I have to restart phone BT and LiquidAUX every time I go into car. And most of the times I can only have 1 connection each time, or phone is on and a2dp is off or a2dp is on and phone is off. It's really annoying since I had an HTC Hero with Android 2.2 and it used to work with no problems...
Hi guys,
Before one month I buy HTC Desire android and I have problem streaming audio through Bluetooth. I have connected the phone with my car and they are paired. Every time when I go in the car my phone is connected to the car Bluetooth automatic, but I'm not able to run A2DP.
I'm with latest Runney rom, before that I tested with MIUI XJ, but no success with both.
Can some one tell me if there is rom without these 2 issues - bluetooth auto connection and a2dp.
Thanks

Bluetooth and how it works with android

Hey guys got some questions concerning BT.
I have noticed that bluetooth doesnt always reconnect when it should. Or am i missing something here.
I have my phone paired with my stereo receiver in my car.
- I get in my car and turn on bluetooth. After about a minute my phone pairs with my car and everything is good. I can do calls, stream mp3's via BT and use Pandora as well. Now i stop at the gas station to get gas or whatever. I shut the car of there for breaking the bluetooth connection. Bluetooth is still enabled on my android. However when i start the car back up the phone will not connect to the bluetooth in the car unless i turn bluetooth off then on again.
I'm assuming this is do to some time out count in the BT stack? is there a way to edit something in order to make this auto connect? Any one with greater knowledge on the subject school me a little bit here?
Thanks!

Car stereo hijacks bluetooth media connection

I have a Pioneer car stereo with built in Parrot bluetooth and media connection. I had this issue with my previous phone so it must be either an Android issue or problem with my car stereo bluetooth. Every time I connect bluetooth to the car stereo the phone enables media connectivity and I have to manually go in and turn it off again. Sometimes I have to turn it on and off again as it says it's connected even though it isn't (tick box is ticked but if I untick it it connects and I have to untick it again and OK it to verify). Also if I disconnect it then cycle through the sources on the car stereo as soon as I get to bluetooth it enables it again.
I don't want it on because I want to hear media audio through the phone speakers and phone calls through the car stereo.
Android 4.1.2 at present.

I think the answer lies in the question here,, Parrot Bluetooth Media Connection.
The stereo isn't 'smart' enough to determine that what is connecting to it is a Phone/MP3 and as such you wont be able to split the audio to have the phone play music and the Stereo take calls, it'll end up being one over the other.
One way around this would be to test with a completely different Bluetooth Headset to see if this allows music to be played on the Device and Calls to come through on the Headset,, failing that its going to have to be a potential dev jobby to split how the device sends its audio and to what specific device,,, if that lies with HTC and Android/Us or Pioneer/Parrot themselves,, might be worth asking whats the official standpoint on this with the Manufacturer and see if they are getting this same issue from multiple folks

I have the same problem with my HTC One across four different ROMs, two GE and two Sense.
It's NOT an issue with my car stereo (uConnect system) as it works flawlessly on my Nexus 7 and VZW Galaxy Nexus. I prefer to have media (music, Ingress etc...) play over the phone. Only thing I want to play over the uConnect is the actual phone. No matter how many times I unselect media in the bluetooth settings it selects it again.
I see this is an old thread, anyone have any ideas?
Nope. It does not always do it though. I found that if I leave bluetooth on it seems to be OK just as long as I don't switch through from aux to radio to CD and back to USB again on the Pioneer. If I use the automatic bluetooth app to save battery it connects but then connects with the media option enabled. Bummer.

I've just installed Bluetooth Auto Connect have to go run some errands in a little while, I'll let you know if it helps out managing profiles or not.
If it works let me know what settings you used as I don't understand all the options lol.
bluetooth problem
Hi developers: Thanks Team Venom for a great ROM. I have only one problem. Rom 2.7 no problem with Bluetooth in the car. 3.1 Installation of clean and dirty disables bluetooth. Ten seconds connected and then disconnected. Again, connects and disconnects. So it all over again. It is in version 3.6 ... any change BT software? You can install the software separately BT? Or any other advice? Thank you very much
edit: I deleted the original settings in the car. Again the connection and still the same problem.

Bluetooth in car connection issues

There is a Bluetooth car connection issue, if I place a call via my car's bluetooth connection, the phone starts to place the call, I hear a "pop" and the bluetooth connection cuts off. None of the call is handled through my car and the car displays "Unknown Number" for just a couple seconds. The phone continues the call but its now through the handset. So, now I'm not getting anything through my car's system.
Need help in resolving this issue. Have tired clearing Bluetooth cache, resetting the connection in the phone as well as the car but to no avail.

How to switch bluetooth when leaving car to go to headset and back again?

I just got a 2017 honda crv lx. When im on the phone in the car i want it to be able to switch to my headset when i walk away then back to the car once i get back in. Maybe there is a tasker profile for this?
Also why does the HU need bluetooth when the phone is plugged in to usb? Is there any way to not use bluetooth but still use android auto?
I have had some issues man...not totally similar to you but this is my issue.
Every time I start my car, Bluetooth connects as it should because I may not want to use AA (Android Auto) and may want to just listen to radio :silly: . I can listen to music from my phone. I can make and receive calls with no issue. My only requirement is that I have to lower the volume of the phone ringer to silent or else I hear the screech of death from the phone speakers when a call comes in. Not the normal situation or ideal at all. Anyway, i have tried to find a way to 1-Delay the time it takes for AA to connect to the HU or 2-Have the Phone go into Do Not Disturb when connecting to the car. I have not figured out a way to do either.
Well, if I decide to use AA, and click on the image on my HU (JVC-KW-M740BT), the same happens....no calls can come in without some sort of loud noise from the Phone speakers. everything else works.
I am just at a loss as to how to automatically set up the silent ringer on my phone when connected. I have been trying to use Llamalab's Automate app....and i have gotten close but no cigar.
If anyone can contribute solutions, to your problem or mine, that would be great.
I had to put in my phone type and such...
Phone:Nexus 6P
Version:8.1 Stock
Car:2015 Toyota Camry SE
Head Unit:JVC-KW-M740BT
