Global vs Nigeria Rollout: Why Delays Happen in 2025

Globally, the patch hit Pixels on November 12, 2025, with Samsung starting November 4 for flagships. Nigeria's rollout lags 1–4 weeks due to OEM localization (e.g., HiOS for Infinix) and testing on MTN/Glo networks.

Factors:

OEM Prioritization: Samsung leads (US/Europe first, Africa last).
Local Challenges: Power outages delay OTAs; 4G/5G variability in rural areas.
Adoption Stats: Only 25% of Nigerian Androids are on patches within 30 days (NCC 2025 report).

By November 25, 2025, 10% of eligible devices nationwide have it—rising to 40% by December.
