Help screen capture randomly in my pocket

[Android Question]

I have a samsung galaxy s7. No phone cover.
My phone takes random screen shots in my pocket. I have turned off swipe, I have removed camera from lock screen.
It does it often during a hands free call taking screenshot of the phone number im talking to or it will sometimes take screen shot of lock screen.
It sometimes does it immediately after I get a message notification.
It probably happens anywhere from five to 30 times a day.

Do you use some app or feature that takes a photo after someone enters an erroneous password ?

Some phones (like mine) also can take a photo if one of the volume buttons is pressed twice.
