Text entry can be difficult occasionally wheh I try to enter, and the text in the box collapses, so I can't read the text as it's being entered. This happens always in the Labels boxes relating to Phone Numbers. I also have an issue where I can't see the buttons to accept, or reject a call. This is often hidden in the display. So answering the Phone can occasionally be impossible for this reason. Sometimes the ICON that resides on screen when I'm on a call dissapears, so I can't easily hang up.
