Just tested on pixel 7a. When I click the power button 5x, a screen appears with: - A large circle in the middle of the screen, which I have to press and hold for 3 seconds to initiate the call. - A slider to cancel the screen entirely So just hitting the powerbutton 5x does not actually make the call on Pixel 7a, just makes it easier.
