I am use ASUS ZenFone z010d. When I purchase my phone then I can't connect my car audio system via Bluetooth. I call to customer care they suggest me for factory reset. Then I try this but the probleme are same. Then go through my nearest service centers but they can not satisfied me. So this phone is very bad.
