Recent reports indicate that legacy applications on the iPhone Duo may not automatically scale across the entire screen. Instead, older apps will run within a centered window, preserving their original layout rather than stretching to fill the display.
This behavior means users can expect black bars or unused space around unoptimized apps until developers issue updates. While this approach avoids distorted visuals or broken interfaces, it places the responsibility on developers to adapt their software to the device's unique screen requirements.
Such transition measures are common when new hardware configurations alter traditional display dimensions, ensuring basic compatibility while the broader app ecosystem catches up.
