Omg 100x yes, the answering UI on modern phones is the pinnacle example of why flat-ui needs to die. It should be the easiest UI to create with only two freaking buttons but still everyone fails so miserably bad. Shape of buttons are identical, colors are very faded and the icons to indicate phone up or down have been flattened so much you can hardly even recognize any of them is a phone. Or even worse are those you need to pick up the button and drag it either left or right to answer, without indication which direction means what until you touch.
Not even Apple gets it right, half of the time the answer button is white and placed on the left side of the screen and half of the time it's green and placed on the right! How fucked up is that??! I thought i was going crazy by constantly imagining the button being on the other side last time i answered but it turned out it actually was!
