Touch screen active when bluetooth device connects. help!!!

Hi had my z2 for about a month now, very pleased with it so far but there is one issue i keep finding that i have narrowed down.

I keep finding my phone will do random things in my pocket when out  and its really frustrating i had tried changing lots of settings todo with the screen as i thought it was when i got a notification it would wake the phone and my leg would simulate screen presses.

That isnt the case however. I have narrowd it down to when i get in my car and the bluetooth connects to my car radio it makes the touch screen active, the screen does not light up but if you touch it as it connects it will wake the phone.

Has anyone heard of this or have a solution (please dont say turn bluetooth off) 

its really annoying me and spoils a otherwise almost perfect phone.

Thank you

The only other thing you can do is change the lock screen security as Swipe to unlock and attatching a bluetooth device like in your car will unlock the phones lock screen
