Android 4.3 worse than 4.1 for bluetooth?
 

Anyone else have problems making outgoing calls from their H/U after their phone upgraded? I have the same H/U that is now the base in all '14 Scions.
I loved how well my phone and the car worked together (not so much the music player but that's another thing). But after the upgrade on my phone, I can no longer make calls through the H/U. I can place calls from the phone and they work through the H/U and I can answer incoming calls, but if I try to place a call using the H/U it goes all the way to the point where it is about to dial and tells me that it can't place the call because the phone is not connected.
If I take the time to completely break the link between them and re-add the phone, it will work until the next time I get in/out of the car. Suffice to say that this is not acceptable.
Anyone else have this problem? Got a fix? I would prefer not to revert to 4.1 because there are other changes that I like.

I found another broken function. It used to be that if I was playing something that was stored on my phone by bluetooth then switched to Pandora, the H/U would seamlessly start displaying the new song information. Now bluetooth always displays the last thing I played from the phone's memory, even if I had used other sources in between.

It appears that the problem is that 4.3 upgraded bluetooth to 4.0 from whatever it was before (3.x) and there was some fundamental change that threw the communication off.
I'm looking into downgrading bluetooth on the phone.

Any luck on this?

I've upgraded my phone to 4.4.2 kitkat and the phone capability of the touchscreen head unit is now completely non-existence. I can make and receive calls on the head unit itself over bluetooth, but no sound on both end of the call.

Oddly, I can still bluetooth stream music from phone over to the head unit.

Have tried to unpaired and paired again with no success.

I'm having similar issues with my BRZ. It sometimes helps if I restart the phone (Galaxy S4) but this is not a real solution. Any tips would be appreciated.

Audio sucks on 14 bespoke. Sounds like speakers are blown over Bluetooth streaming

My saga got worse. I went to the Samsung store at the local BestBuy and all they could suggest was doing a reset of my Note2. Now the only phone book the car sees is the damned AT&T one, which I don't use. I open contacts on the phone and they are there (mostly) but I get an empty phone book on the H/U.

4.4 and the second gen of 4.3 bluetooth radios seem to work. (I tried via AoKP on an S3).

I just got a samsung note 3, and the stock hu doesn't even transfer contacts, and don't even make calls... whats going on??

Hey guys, I've noticed under my bt settings in my phone, there is a visibility timeout. It was set to 2 mins. I just set it to never timeout. I'll see if that works

Ok guys it didnt work. I can play pandora and iheart radio just fine. But everytime I try to transfer contacts bluetooth disconnects... sigh

Hmmmm just connected my friend's iPhone via Bluetooth and it sounds amazing

Mine is an AT&T Note 2. It worked fine under 4.1 but as soon as it updated to 4.3 things went south. My original thought was that bluetooth was the problem but I no longer believe that. I think it is just a poorly written implementation by their developers. I just dumped the factory rom and went to a custom one based off Kitkat (the latest) and everything appears to work with the car again.
The only problem I have has nothing to do with the car, and that is that the contacts will only read off the simm and don't download from my Google account.
