Phone Platform Optimization Work Order

Display and graphics

Optimize scanout, framebuffer format, bandwidth, underflow detection, and the Android HAL boundary before any GPU/display product claim.

Camera

Camera work is blocked on sensor selection, CSI, ISP ownership, tuning package, calibration records, privacy indicator policy, and HAL or V4L2 transcripts.

PMIC and platform IO

PMIC, USB, storage, radios, and sensors must be treated as coupled product systems. Each needs selected hardware, firmware ownership, power/reset/wake lines, Android service declaration, SELinux policy, CTS/VTS or equivalent evidence, and negative failure-mode tests.

HAL

HAL work must remain fail-closed until boot logs, VINTF, service dumps, and runtime transcripts show the backing device nodes and services exist.
