This issue has been elusive to detect. See comment here
https://github.com/codenameone/CodenameOne/issues/2317#issuecomment-365372296
It is scheduled for 5.0 unless some major breakthrough occurs.
You can workaround it in the meantime by adding the following to your text
field:
textField.putClientProperty("android.cursorVisible", Boolean.FALSE)
This disables the blinking cursor in the field, which strangely fixes the
issue of disappearing text in some (not all) older versions of android.
