Hi all,
I seem to be having all these issues since I updated to 4.4.9344
Additionally, I also have the problem that in the home screen and every time I send the device to sleep or power off, the percentage of the book I have read is stuck at 65% and won't change, and when I open the book it sends me to the chapter that is at the 65% of the book and I have to manually go to annotations to go back to the chapter I was actually at. This is so annoying! I had several books started and it's happening with all of them (but with different progress percentages).
Regarding the other problems... I am manually turning the device off every time I finish reading to keep the battery from draining, since even if I set the light to 0% it seems to go back to 1% on its own, and to set the light to 0% I use the menu at the top of the screen.
The issue about the touch not responding only happened to me once, and after rebooting it seemed to be OK.
I really hope Kobo launches a firmware upgrade that fixes these issues, because apart from them I love my e-reader.
