This no longer seems to be a problem. I'm not sure if a system update fixed this, but, the options button now works for displaying Description text if it does not fit on the screen. This did not work before. My device is running Version 7.5.1 Build 4111-29. The problem is fixed even though the 'last system update' was in February.
