Assessment scope
Desk research as of 2026-10-24; no physical testing. Platform-level controls are distinguished from model-specific exploit evidence. Ratings are qualitative judgments using the form's limited categories, not measured incident rates. Operating system denotes the launch version. Regional memory configurations and update rollout can differ. The release_date field above uses the announcement date (2021-04-08); retail availability differed by market. Current support status is assessed as of October 2026.
