Notes
Launch/announcement or regional availability month reference: 2023-03. Source: https://en.kalvo.com/oukitel-wp21-ultra-85123.html. Manufacturer UK PSTI table explicitly lists WP21 Ultra V01 within its January2024–January2027 minimum security-maintenance window. January2027 is the published minimum-window endpoint, not an exact last-patch day or guaranteed permanent stop; may be extended. UK/V01 reference, not universal across all regions/hardware editions. Not three years computed from launch. Future Android major upgrade count unverified.
