Bluetooth problem after update to lollipop

[Goral08]

Hi,

I've recently updated my 6503 to Lollipop.

Everything went smoothly and is working fine, except 2 issues - one solved, second NOT.

FIRST (solved) - phone after update waked up and logged to 2G network, with no data transmission (despite it was turned ON). What was strange - my operator's network appeared in 'available network list' as separate 3 NETWORKS ( 2g, 3g and LTE) Switching manually to LTE solved it - now phone is switching between technologies automatically, data transmission is working fine.

SECOND AND NOT SOLVED: I'm using the hands-free system built in my car ( mitsubishi lancer, 2008 ) . After update, phone failed to establish connection with it, even hands-free system remained as 'associated device'. OK ... I erased hands-free system from phone, as well as phone from car's memory. Paired devices again - starting procedure from car's side. Nothing better. Erased and paired starting from phone side. Nothing better.

What I've  observed more: phone after try to establish connection , phone in eye blink looses it. On list of available services of hands-free system (in phone menu ofc) , only 'phone sound' appears, while -as I remember but i'm not sure- before update more (2 or 3) services were detected .

 PLEASE HEEELP !

Contact the car manufacturer regarding compatibility with Lollipop.

Its not a problem with car - everything WORKED before update, after - NOT. BT standards haven't changed.My car is the same, too.

Something is WRONG with bluetooth implementation in lollipop for z2.

Similiar problem raised NileEve today, in topic 'connecting to my car'.

Additional information to my issue: yesterday at evening phone connected succesfully to car, i was able to receive and make a call through hands-free system all the time returning home. Today everything returns to the beginning (failure). More over, i tried to manually connect to the hands free sysstem from the phone menu ( as one of the paired devices) - but without success ( in eye blink BT connection lost).

My suspicions: BT stack overflow? Stamina or similiar process cancelling link ?

You suggested contacting Sony Xperia Support - but this is 'support forum', isn't it ? At least 3 users from different countries have same problem , could you help us THERE ?

Any suggestions ? Phone is connecting with hands-free system once per 40-50 trials ...
