I had the problem with the backward button.
Each time I used it, i jumped 3 or 4 pages back (instead of one).
No problem with the touchscreen (which i don't really use to flip pages)
I returned it as defective.
The one I have now is OK.
What i would like to know is the firmware version of your reader.
I updated the first reader to the latest firware version.
As I don't have any problem with the new one, I'm staying with the 1.0.00.09270 version
