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

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

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...

Thanks. At least I am not alone!

Just as a follow-up, I have installed iOS 12.0.1 update, but the problem remains.

I have contacted Citroen Customer Support and they have finally go back to me today with a request for details regarding the car. Not sure if I will get anywhere with Citroen, but I will post any results here.

I have exactly the same problem! Bought a Citroen C4 2011 last week and Bluetooth connects fine. But mobile handsfree never does. I connect it and it connects for 10 seconds then disconnects again! So frustrating! Also the car doesn’t recognise the phone when I put it in the USB.. Which again is probably because of the latest update on iPhone. I have to use a AUX as the sound quality is so poor via Bluetooth. Hopefully there will be a solution soon.

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.

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

Nov 4, 2018 1:04 AM in response to Abailey152

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?
