Just press both of button (down vol& power button) BUT NOT too quickly. OR
Hi, same problem here too, after update the screenshot no longer works pressing Vol down and power button, it goes to power off screen, nor can I swipe to screenshot even tho it is turned on in settings . Very annoying as this is probably one of the features I use the most, Please Help !!
My bad, didn't read all the replies, and yes, it works pressing the vol down and power button by quick pressing both not long pressing as it used to
