- 2026-10-23 — CarPlay full screen: not possible on this firmware (SWI68). The export from the
car showed CarPlay's window at 1920×720 with both SAIC bars hidden (policy_control on), and its
video SurfaceView at (0,80), 1920×640, with a 1920×640 buffer: the grey strip is the window's own
background above the video. Allgo's `/system/app/AllgoCarplay_EH32` hard-codes it twice:
`CarPlayService` announces `SCREEN_HEIGHT = 640`, `SCREEN_WIDTH = 1920` to the iPhone (it reads
`sys.screen.heightpixel/widthpixel`, then overwrites them with the constants), and
`carplay_screen_layout.xml` places the SurfaceView at `640px` high with `80px` top margin. Both
are in the read-only, signed system image. The export (`dump/`) is gitignored: it holds Allgo's
software.
