Hello,
When I plug in my Samsung Galaxy tablet, it takes a much longer time than normal to process (the 'Jobs' indicator in the lower right stays at 1 for about 10 minutes before finishing).
After that, no books have an indicator in the 'On Device' column, even though there are a lot of books (EPUB, MOBI) in the BOOKS directory on my storage card.
I has worked fine for a long time and I am not exactly sure when/how things went wrong. I am pretty sure that I have updated Calibre a couple of times since the last time I plugged my tablet in to administer the books on the tablet. Whenever I see an indicator that there is a new version of Calibre, I do the update immediately.
I took a look at the 'metadata.calibre' file in the root directory of the storage card, and it seems to have the names of the books that should be there, but the 'timestamp' and the 'authors' tags all seem to be blank. I dont know if they were blank when Calibre was working properly or not.

Any ideas on what went wrong and how I can fix it?
Thanks in advance.
