Why bluetooth is turning on automatically

[Android Central Question]

I have HTC 10.
When I unlock screen often I see that Bluetooth is on. After the screen is unlocked Bluetooth turns off in few ms or one sec.

Something must be turning on my Bluetooth when the screen is off and turning it off when my screen goes on.

I am trying to figure out why or what is doing this.
