Hi, I just bought PocketBook 602, and having the following issue: whenever I press forward or backward buttons, I am getting the next (or previous) page. But then, 5-10 seconds later, device moves yet another page ahead - in other words it navigates two pages instead of one. It behaves the same way with menus - when I open a menu, 5-10 seconds later device opens the first item listed on the menu, as if it were clicked. There is positively no way to stay on the selected page, and device is practically unusable. I am wondering if it is a known issue, or unit defect. I contacted tech support, but got no response so far.
Note: I haven't update firmware yet since I don't have microSD card at the moment. Can I boot it from USB flash drive?
