Official-document review, original concept diagrams, and real-device checks are disclosed separately.

Three verification levels

Official-source review: Primary material from OS providers, device manufacturers, or carriers.
Procedure and risk review: Data impact and safe troubleshooting order are checked.
Real-device screen check: Device, OS, and date are listed only when an actual device was checked.

Images

Images labelled as concept diagrams show diagnostic order. They are not copied manufacturer screens or real-device screenshots.

Current status

Phase28 strengthens official-source and procedure review for 30 priority guides. Real-device images will be added only after a specific device and OS are verified.
