I successfully flashed my test device with Tizen 2.2 and installed the graphics drivers. Everything works fine and I have no problem running my apps developed with Tizen SDK 2.1.
However, when navigating the Tizen 2.2 user interface it looks like it has been developed for devices that have several extra hardware buttons like a back button and a menu button. For example, when I go to 'Settings' and then to 'Home Screen' there is no way I can go back to 'Settings' because there is no software back button in the form of a curved arrow at the bottom right corner of the screen and I don't have a hardware back button on the device itself.
I haven't yet installed Tizen SDK 2.2 but I wonder whether the emulator has extra hardware buttons besides the single home button centered below the screen as in Tizen SDK 2.1?
Does anyone know whether the newer Tizen device models will feature extra hardware buttons?
