I decided to restore my Voyage to factory settings as I had put too many books on it and the battery was draining every few days (or whatever). I typically do this every 6 months or so with my ereaders.
Always, when I open the cover, there is a cover page and I have to swipe to get to the "last page read." I thought this was because I had advertisements.
The point is that when I was done with the Restore, I loaded a few books (<10!) and started reading. Now, when I open the cover, the "sleep" page flashes for a second and then it automatically returns to the last page read!
This had been my only real complaint about the device, so I am very pleased. I had no idea that I would get this feature, so figured I'd write this post in case anyone else wants to try. The auto-brightness feature seems to be more precise as well. This is a great feature as I read in way-varying lighting conditions each day. Cannot distinguish any other changes, but this is quite enough
I am very pleased with the Voyage after using it for 6 months, reading 2-5 hours every day. I am an older reader with not-so-great eyesight and it is soothing for my eyes, even after many hours reading.
