Phone: End Call button not visible
Voice calls should be able to be terminated at any point of the progress of the call, such as during ringing.
Today I tried calling a friend of mine. It soon became obvious that he wasn't answering, and I wanted to end the call while his end was still ringing. (Mobile to mobile, different providers, if that matters.) However, this proved to be somewhat difficult. The screen remained black apart for short glimpses initiated by a double tap or a press of the power button. During these, it became apparent that the End Call button, wisely placed at the bottom of the phone app, wasn't visible - neither was the pulley menu at the top. In its place was a blank strip of textured "glass" about 15 mm wide, which seemed to "push" or shift the entire main screen down just so. Unfortunately no screenshot, that would have been a miracle, given the finicky nature of the device at the time.
Operation was restored to normalcy as the network finally gave up with the ringing.
