Auto-answering doesn't work while using bluetooth headset

[h7kn]

i have tried it with 15 different applications and 6 different bluetooth headset, this is the most bizzare problem of Z3 compact.

Auto-answering doesn't work while using bluetooth headset. i have tried it even with the original Sony bluetooth headset, there is no solution.

now i have to push answering button on my headset for incoming calls. im a dentist and this problem is my nightmare.

please help me. thanks.

i got the same problem after 5.1 update. i was using bluetooth headset 100% handsfree before the update, even i could reply incoming calls after 2 seconds with my bluetooth headset. this was allowed by phone itself. 

i agree that all the brands have automatic answering functionality except with the Sony.
