iOS 12 Bluetooth problems

I've just installed iOS 12 on my iPhone 7, and since I cannot get my car handsfree (a Citroen C3 - 2012) to work properly with the phone.

I can pair okay, and all seems correct but less than a minute later, the car loses communication with the phone. That is, it can see the phone as a bluetooth device but does not recognise the phone capabilities. No calls can be made, the battery level cannot be viewed and no media can be accessed. On the iPhone, the car is shown as BT RADIO, and is shown as "Connected".

If I tell the car to connect Telephone or Telephone + Media, it will connect again, but a few seconds later the same occurs.

I have tried the following,

1. Turn Bluetooth on and off on the phone.

2. Forget the connections on the car and the phone, and re-pair.

3. Reboot phone.

4. Hard reboot of phone.

5. Forget the connection on the phone and car, rename the phone and pair again.

6. Reset Network Settings.

Nothing has worked.

This all worked fine and various versions of iOS 11, so my only conclusion is that something has changed in the Bluetooth system in iOS 12.

I don't want to try to wipe my iPhone and downgrade, so I am hoping all the complaints will prompt Apple into looking at what has gone wrong and release a fix

Just as a follow-up, I also have my iPhone connected to my home DECT phones using bluetooth and this seems okay. Perhaps it is a standards issue affecting older Bluetooth systems?

If anyone has had this issue and has managed to find a work-around or fix, please let me know.

Thanks in advance.

iPhone 7, iOS 12

I have and Citroën C4 2012 e-hdiafter ios 11.x and now ios 12 i had the same problem. Worked Well with ios 10

so I do hope that @apple will have a serious look at the bluetooth mode, so we can enjoy handfree speaking again.

My media player connect fine, the Phone connects When i reconnect to the car. Then it disconnect from the telehone, but not the media connection.

hope anyone who has a solution post it here 😉😎

Hey! I just discovered a bug which is a feature I guess.

When I turn on the C4, I'm then activating the google maps app *with voice assistance*. Then I place a call and turn the voice assistance of the map off. The call remains connected for the whole ride!! I've already tried that twice, and both time it worked.

Let me know if this worked for you as well?

Good luck

Hi!

Finally I found you people with the same iOS 12 Bluetooth problems! I have iPhone 7 with 12.1.4 and my car is Peugeot 508 2011. Worked ok before upgrade but now the handsfree function is useless. Stays connected fine for half a minute, then the phone disconnects while the media player is still connected.

I have tried everything! Thinking of buying a separate handsfree speaker for the phone part. But ok, first I may try the suggested voice assistance trick even though I don't use Google maps app, use Apples Maps.

So see you later...

As yen-ki-ya proposed I can stay connected if I place a call directly when my iPhone and car radio connects! I don't have to turn off any voice assistance, just place the call before I loose my phone connection (after 30 sec). The media player connects fine all the time. And I can cancel the call right away, don't have to wait for the signals to go through, the phone stays connected until I leave the car. Next time, same story...so it´s not a permanent solution of course. Still a problem, so I mostly use a handsfree speaker.

After the Bluetooth connection working for years, my Peugeot 508GT year 2011 then had the same problem to my iphone 6 on the previous Apple s/w version.

Version 12.0 arrived and filled with hope I download it - but same problem - Apple STILl have not fixed it.

Ah............I tried the trick mentioned by jen_ki_ya of getting the phone connected properly to the car ( phone, not just media) then immediately calling any number - even one I know is now disconnected. THAT WORKED ! - the phone stayed in Bluetooth contact with the car. I tried both with, and without, Siri turned on, still OK.

So sure, it is a little tedious, but at least a definite work-around - anyway useful for long car trips

I have found a solution that works perfectly. When getting in the car and turning the ignition on. Wait until you see both media and phone connected (denoted by the display of number 2 next to the Bluetooth icon). When this happens activate Siri and say hello (you have to say something and have it respond) once Siri has responded press the power button on the phone to lock the screen or close Siri.

Done me you will have full phone and media until the next time you start your engine.

i do this every time I get into the car without thinking now.

Another workaround is to have a bluetooth headset turned on in the car.

A theory that @Apple should test, it seems like there is an "IsAlive" message send from iphone every now and then, but it is only send from the media connection, not from the phone connection, hence it disconnects after some time.

that would also explain why it works if other headsets are sending the message.

It doesn't explain why Bluetooth works perfectly with most devices on the market.

There has to be something unique going on with the devices that experience a disconnect, but I can't imagine what it would be.

I also have the same problem on iPhone 8 with a Citroen C4. thank you for correcting

Hi Abailey152,

do you have new results. I have the same problems with an C4. Even with iOS12.1. I hope you have good news.

Thank you.

Thanks!

So i'll consider changing to Android if Apple doesnt soon enough - solve the problem.

As one driving 100-200 km / average day, handsfree is pretty important.

I have exact same problem with my citroen c4 2012 and my iPhone xs max. Had the same problem with my iPhone 7 after updating to ios 12. Hope for a fix...

I know this is an old thread, did anyone know if there is a fix for this? As I have a DS4 and Bluetooth disconnects after about 10 Seconds media plays fine.

Have you tried deleting the pairing from both sides and re-pairing?
