[Galaxy A7] Why does my bluetooth turn off when making and receiving calls?

[AC Question]

My new smartphone is Samsung A7 double SIM. Whenever I make or receive calls bluetooth turns off and all bluetooth connected devices disconnect. After call is ended, bluetooth turns on on its own and devices get connected again. Never happened before with many Samsung double SIM devices. Any explanation/suggestions ?
