djb123: have you tried any of the software-back-button apps? Alternately, have you tried asking Onyx (sales@onyx-international.com), or the Netherlands distributor, how they expect users to emulate the back button on a device lacking the physical button? (I've read through the Kepler manual, and can't remember finding anything on the topic.)
Incidentally, the Android CDD (for 4.0) states the following:
Quote:
7.2.3. Navigation keys
The Home, Menu and Back functions are essential to the Android navigation
paradigm. Device implementations MUST make these functions available to the user
at all times when running applications. These functions MAY be implemented via
dedicated physical buttons (such as mechanical or capacitive touch buttons), or MAY
be implemented using dedicated software keys, gestures, touch panel, etc. Android
4.0 supports both implementations.
