Apple’s iOS 17 update, announced at its annual Worldwide Developer Conference (WWDC) in June, didn’t usher in many controversial changes. That is, apart from relocating the end-call button to the bottom right-hand side of the call screen gird.

However, the Cupertino company has now reversed that decision, shifting the end call button back to the center-bottom — similar to where it was in iOS 16. People probably didn’t like the change in the position of the end call button because they might be used to tap that part of the screen to end a call without looking.
