After I disconnected my smartphone from USB port of my computer without using Unsafe Removal, some programs in internal memory disappeared, including DueToday.
I reinstalled DueToday but now it does not have any tasks.
I haven't synchronized my tasks, so it seems that I will have to restore tasks from the latest backup text file create from within DueToday.
It's a pity that recent tasks will be lost.
What if I root my smartphone? Will I be able to find a file with tasks in internal memory and somehow suggest it to the newly installed DueToday?
