Notes
Launch/announcement or regional availability month reference: 2025-03. Source: https://en.kalvo.com/ulefone-armor-28-ultra-thermal-128843.html. The official 2026-08-29 statement and OTA list name this SKU on the Android 14 to 16 path: 2 announced steps, not a fixed final OS ceiling. The minimum two-update policy for eligible newly launched models is not retroactively applied to all legacy devices. Rollout varies by region; no universal installed firmware or security end date asserted. Current stage: coming-soon.
