When an USB hard disk drive is disconnected from an USB port, the hard disk icon on front VFD display does not disappear. Tiny white moving dots can be seen at the right side of the screen when browsing files in MEDIA CENTER app. Some texts are overlapped when 'Font Size' is greater than 'Normal' under Android Advanced Settings. Tested with firmware: 1.4.6. Regards UPDATE: Bug report has changed (changes are highlighted in red). Please see my reply to know changes.
