SGA5 2017 - disconnecting from BT, when start call - Samsung Galaxy A3, A5, A7 (2017) Questions & Answe

Hi, I tried to find something about the issue, which I have, but nowhere is the same problem, so I tried to create the new thread...
I have the company phone Samsung Galaxy A5 2017 (SM-A520F) with the stock ROM (now with Oreo) and I got the new company car with build-it bluetooth (Volkswagen). I tried to pair the phone with the car and everything looks good. A few first calls were without any trouble. But now happens very ofter (almost in 99% attempts), that I have connected phone to car and
- somebody call me
- I call to somebody (via touch on contact in infotainment in car)
- I call to somebody (via touch on phone application on mobile phone)
the call is starting and in the same time is the BT connection interupted. And there are two possibilities:
- BT on SGA5 is still turned on, but disconnected from car
- BT on SGA5 is turned off (somehow)
You can say, there is trouble with your car, but I tested is with the other mobile phone (Nexus 5X) and everything works properly.
That's why I think, that the trouble isn't in car, but in the phone. And of course I did the wipe of whole phone and after that I tried it again, but with the same results.
Does somebody the same/similar experience? Is there some solution? Because no possibility to call in car is horrible for me and I can only get a new phone in the summer (it is too long time without call from car).
Thank you in advance

[Q] Bluetooth Problems

Hi,
I have a bluetooth phone in my car, when I first connected the HTC Desire HD up, it had no problems, it paired and everything looked fine... around 10 minutes later, I noticed the bluetooth had simply disconnected from the car but was still running on the phone. I tried to reconnect it up to the car but it wouldn't, I then turned it off, and turned it back on.. it struggled to come back on, but after a few attempts it did come on and the car connected again...
About 5 minutes later the same thing happened again. At this point my phone started to really slow down, I looked in watchtower and the bluetooth was at the top of the list, soon as I turned off bluetooth the phone was responding fine again.
I have since tried connecting to the car multiple more times and have contacted HTC about it, but it seems to disconnect at random times.
Has anyone else experienced similar problems? I heard of similar problems with the original desire so wondering whether it could be something similar.

Hi Kev,
I am having similar problems with my Desire HD and Audi in car bluetooth system. I posted on another forum and found others were finding the same...
I pair my phone and within couple of minutes the phone has disconnected and won't re-connect.
Not found any definitive answer as yet, but seems BT in this phone isn't so good. Also read a post saying HTC were aware of this but an update wouldn't be available for sometime.
Hopefully someone else can shed some light!

I also noticed this the last few days with my Bury CC9056 carkit. I have my DHD since October 18th, and up till last friday it connected fine. Since then it connects to the carkit, but within a few seconds the connection is lost...

Me too. My connection to my Jabra car kit is stable once connected... but trying to get it connected in the first place is a total headache.
Never had this problem with my Desire, so why HTC should change the Bluetooth function in the HD is a mystery.

tbh i'm glad its not just me thats experiencing problems meaning it could be a software problem rather than something with my handset in particular.
I have been in touch with HTC about this, and I have just sent them the link to this thread so they can see i'm not the only one with this issue, so if anyone else has this issue it may be good to try and keep it all in here.

Mines also the audi in car system - do you find that you struggle to turn the bluetooth off and on again once it disconnects or that your phone becomes a little laggy until you turn the bluetooth off?
Yeah - I use the bluetooth widget on the home screen and once it disconnects, it will either take ages to turn off and on again, or it takes 2 presses to turn off.
I have just purchased a Plantronics 230 headset as need bluetooth for my job and it works perfectly - it's no where near the quality of the in car one though.
Also booked in my Audi as it's still under warranty - spoke to them on the phone and they said they will try and update the firmware but the Desire HD isn't on their supported phone list. Have seen a copy of this and not many phones are!!
I would of thought though, that as long as the phone does connect to the phone system in the car that it is compatible.
I have had 30mins once out of it before it disconnected and it was absolutely perfect in that time, including the phone book etc.
I do believe its something to do with the bluetooth on the phone as its a bit strange the way it struggles to turn on again once it fails.

That really hacks me off. I mean, BT is a standard. The only reason Audi can give for not supporting a phone that supports at least the same level of BT as them is that they (Audi) do not adhere to the BT standard.
Now, we all know in real life that cars and phones have problems/bugs/whatever BUT unless they can show that there is indeed a *bug* with the phone then the onus should be on Audi to support it.
Dave
Just for the record, it is not just Audi. With me it is together with the Bury carkit, where it first worked fine. (and also works with all other phones...)

I can confirm the issues with the BT. I have a parrot Mki9000 in my car and the first time when i tried to connect the DHD , the phone stopped to respond and I was forced to restart it. Since then the phone is paired with the car kit and works fine in a2dp mode for playing music, but when i try to make a call it simply not work. Yo better discribe the problem I will give an example:
The phone i properly connected and playing music, then it's ringing, but the ring sound is coming from the phone speaker not from the car. Then If i answer the call the sound comes from the phone (it shows that there is connection to the car kit). I've tried to press the speaker icon and there is a list with output devices (the phone, loudspeaker, and my car kit) I've tried to select the car kit several times , but there was no success. When I close the phone the music start to play from my car's BT system , so I think there is a problem with the handsfree function/protocol only a2dp works great , and I didn't have any issues with it. Also I've tried file transfer via BT, it works fine two.
Mitsubish Outlander carkit
I can confirm the same issue with the Mitsubish outlander carkit. It even happens that it drops the conversation. sometimes it's ok for half an hour, sometimes it disconnects after 1-2 minutes.
I also have a Jabra (bluetooth) headphone and noticed that if you pick up a call on the phone the sounds doesn't route to the headphone. If I pickup on the headphone it works fine.

I have a Pioneer head unit with BT in the car and that seems to work OK, not withstanding the fact that the HU has BT issues of its own (hardware fix needed - I'll get a new unit rather than fix it as I want one with A2DP) but once connected it works fine.
I have a Plantronics headset that seems to exhibit the same problems as your Jabra. At least if I use the phone to answer the call the sound comes through the phone. Also, if I have been using the headset the next call I make goes through the phone speaker which is a pain.
I'm wondering if HTC are routing the sound through the device that's actually *controlling* the call? So even if a headset is paired and connected to the phone, if you use the phone to make the call, as most people would, then it assumes that that's where the sound should get routed. If so, doh .....!!!!!
Just to add, if the sound does get routed to the phone you can use the 'choose speaker' option on the screen to route it to the headset but you shouldn't have to do this.
Anyone reported these issues to HTC and got a meaningful response?
Dave
I did send an email to HTC. Their wonderfull answer was about: "is your phone mentionned in the compatabilylist of the carkit, if not drop the problem there"...
I am still waiting for a response from HTC.
Mines got to a point now where I cant even make a call, it connects to the car, I go through phone book (on car) choose person to call, press call.. it tries for a couple of seconds then comes up disconnected, about 10 seconds later the phone disconnects from the car and will nto reconnect.
My phone then lags like mad until I turn bluetooth off which according to watch tower is taking up about 80% of the CPU.
any updates/solution to all these problems ?
I need it to work with MW600 before buying Desire HD
Last contact I had with HTC is they told me it had been escalted to the software team, so i'm guessing next time a software update comes out it could come about in that, but at the minute no still not fixed.

I've always thought that that's the way it is on all BT headset phones, it makes sense, if the incoming call was for my girlfriend, she can answer from the phone itself, and it automatically routes this through the phones speaker, and if it was answered from the headset, then it routes to the headset.. makes sense to me, I think it's quite good that it does that!
Do any of you have the process com.android.phone crashing when making a phone call through BT?
Ditto my mitsubishi outlander factory bt system. Seemed to work fine first time but then disconnected during first call and would not reconnect for days. Then after connecting not all functions would work ...no incoming call alert on car system, no dialling from car etc. I know the car system is fine as all functions work perfectly with my old nokia xpress music.

I trust that all of you bother to report this to HTC, at least once per instance ?

Bluetooth in Car Not Auto-Connecting

Is anyone else having issues with their 5x connecting to their car's bluetooth automatically (I drive a 2015 Subaru Forester)?
My Nexus 5 would always just automatically connect, but since I switched to the 5x I have to either connect to the car from the phone or vice versa.
I'm sure I could work something out with tasker or whatnot, but that feels to me as though it should not be necessary?
I have yet to get back in my car after pairing to my bluetooth adapter (I just paired this morning) but I will check later.
Do you have a list of saved or prioritized devices in the car? I wonder if the Forester bluetooth is trying to connect to your first device (Nexus 5) unsuccessfully.
I have a 2014 Ford Focus. The bluetooth will connect automatically, but I have noticed weirdness when placing calls. The car will take a while to initiate the call and then display an error saying "call cannot be completed". Then, 2 seconds later the call audio (ringing) will occur.
I am hoping that these are just some initial bluetooth issues that will be ironed out.
I had deleted my old device from the car's memory.
Another thing I am experiencing is that even if my phone IS connected, the calls are going through the device, and not my speakers.
It still pauses the music...
It could be either my car or the device. I've heard of other Subaru owners having issues with multiple devices in their car, just wasn't sure if it was a little of Column A and B. It seems likely enough it's a little bit of both.
No issues at all. I have a 2012 Dodge charger with the 8.4 Uconnect. This phone actually connects quicker than my S6 edge did and the sound is louder at max volume (on the phone) than the S6E. The only thing that doesn't work is the text messaging from the Uconnect, but overall I am very pleased.

My in-laws own a 2015 Forester so perhaps next time I see them I'll try to pair my 5X. May be a while before that happens though so don't hold your breath
2013 Honda Civic here (so cool, I know). I'm getting mixed results on it automatically connecting. Sometimes yes, but other times I need to connect manually. Yesterday, Bluetooth audio got really choppy in the car, and I had to restart in order to stabilize that again. Have not seen the choppiness issue with my other Bluetooth devices.

I had no problem with my Mazda 5 connecting to my Moto E on 4.4.4, but since the upgrade to 5.1 I now have to turn bluetooth off then back on every time I get in the car for it to connect. Also, the connection can drop. I tried deleting existing connection data from both car and phone, setting up from scratch, but it hasn't made any difference. Wish I could downgrade by phone's OS back to 4.4.4.
Might depend on the sound system. Reconnects to my 2013 VW Passat every time.

No issues in my Audi or aftermarket radio in the Subie... It sounds like you may not have calls being routed through the phone (based on your comment), maybe that is causing the connection issue? Something like only a phone connection is automatically connected (and the audio comes with it), but an audio connection is not?
I have a 2011 Mitsubishi Ralliart and i don't have any issues with my 5X auto connecting to the factory bluetooth system, my problem is the factory bluetooth is garbage since any time someone calls there is too much interference i can't hear what the other person is saying.

Exact same issue here but with a Kia. As soon as the phone "reacts" to a call being started on the headunit, the headunit says "call was hung up". As soon as the call is answered, it offers to be used for handsfree. It's as if the phone's "CallStatus" messages over bluetooth aren't correct
Subject crosstrek 2014, BlackBerry z10 never had an issue whatsoever, but since I got my 5x, I get half a connection (Bluetooth connects with no audio), with 6.0.1, no automatic connect... Blackberry's reputation may be downhill, but I sincerely miss its reliability and the hub...
Nexus 5X and 6P Uconnect 8.4 Grand Cherokee 2014
I recently started experiencing a similar issue.
I use my 6p for music and audio only, and my 5x for phone calls and sms.
About a week ago, they would stay connected as long as nothing was being streamed. However, as soon as I received a call on the 5X, the phone would lose BT connection to the system, and then connect back after about 30 seconds. It would do that throughout all of the calls, regardless of the length of each call. After the first 2 calls, I started streaming music from Google Play Music on my 6p, and the same thing would happen.
I removed Uconnect from both phones, and both phones from Uconnect. Paired them back again, and it is still doing the same thing.
I will try resetting the Uconnect to factory default later today and see if it has any positive effect, and will post my findings here.
If anyone else has a uconnect system with the same issue, please post it here, and we can try looking for a solution together.
Thank you,

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 Bluetooth issue

Hello since I made the last update I have noticed that there are problems with the Bluetooth. I always keep it active to keep it connected to the smartwatch. I have found that often the phone no longer recognizes it and there is no way until I restart the phone. The problems are accentuated when using the wifi hotspot.
Yep the whole coms system on the 6 is poor. I have disconnection issues with headphones and wahoo cycling computer. Just no fix despite resets .

Yep, my 6 Pro Bluetooth connection to my car has gone backwards in quality in the latest 12.1 stable build
Mine will be fine for an hour and then suddenly disconnects all devices. Then it reconnects on its own. It's not fun when you are on a call or virtual meeting.
Mine is staying connected to my watch without any issues, and when connected to either my car or earbuds I don't get any drop outs at all.
This is on the March update, but I don't use it with a hotspot on the phone though.
I am hearing impaired and have my 6 Pro paired with hearing aids, my car, and my smartwatch. When the phone rings, it is anybody's guess where the phone's sound is going to go. It is so frustrating. In my OnePlus 7 pressing the volume up or down would let you pick where to direct the audio but the pixel doesn't see that as necessary. Boy is it ever!
No issues with the connection to either car, but here's an odd one.
I have a connection to my Samsung Galaxy Watch4 & my Plantronics 5200 headset.
From time to time, if my phone rings, I put on the headset & turn it on, it will connect,'
answer the call, then anywhere from 20-45 seconds later, disconnect the headset and
put the connection back on the phone. Doesn't do it all the time.
Everything is up to date, stock, not rooted.

Question No audio when making calls in the car

My Bluetooth in car works great until I either get a phone call or try to make a call. It only comes through the phone. I've deleted both profiles, car and phone, reconnected, still nothing. When I pick up the phone there is no option to use the cars multimedia system. I'm on the pixel beta program, maybe that's the issue, I don't know. Any help would be appreciated, thank you. 2011 Toyota Camry.
Welcome to Google fixing bluetooth issues, ever since they said they fixed the bluetooth issues (I never had any) they broke them for me, since Feb update my bluetooth connections to every device I own drops the connections. I have repeatedly removed and readded, even at one point my phone lost every connection anyways and had to add them again.
THe call issue you raise happens to me on any bluetooth device, I generally have to switch bluetooth off and on again, or just switch to the phone no bluetooth. My car also looses all the information on the display from bluetooth, music will drop and if I press play it will start to play again with no info until I disconnect the phone and connect again, this happens in two of my cars
My Bluetooth has been fine all along, since the end of October when I got my phone, and is still fine now in the car or with anything else I've paired it with.
I wish I could offer some helpful suggestions. I hope the issue gets fixed for you. On a side note, I wonder which old Bluetooth standard your car is based on and if that has any impact on whether someone has an issue or not.

You could try changing AVRCP to v1.4 (in Developer options), then re-pair phone.
Last option would be to reflash Android using AFT (back to public stable)
That's what I was afraid of, I'll try the first and most likely end up doing the second.
