To conclude the talk on the sizes: - Currently only 5.5 inch is considered. I don't find any problem with operations in SFOS on 5.5 inch, and it's generally a great balance overall with battery, screen, camera, a more PC towarded UI. - To get a device like 3.5 inch or 4 inch, it's not possible for now and I don't see any point doing that. - Time to move on.
Because I don't have money to develop 5" or even smaller from scratch...
