Are you turning the page with your left hand?
Yes, the page back tap zone problem happens when I hold it with left hand alone. And the reading progress zone problem happens when I hold the device from the bottom with both hands with thums on. The second one is not much of a problem but first one makes me to baffle when the top menu is opened and my thumb doesn't reach out of the menu.
