Use Apple’s iOS 26 compatibility list as a current-major-OS signal. Do not infer a future support-end year.

Check used-phone OS and security support with exact-model official signals

Across 515 smartphone sales records, this separates Apple current-major-OS compatibility, Pixel long-term update policy, and Samsung current security cadence. It does not guess remaining years from a Japanese carrier release date.

Support life is not inferred from release year alone
A fixed rule such as “a phone is old after a certain number of years” can misrepresent manufacturer policies and exact-model support. This database separates current official OS and security-support signals from the sales records used elsewhere in SolQvia.
Explicitly documented support and fields that still require exact-model confirmation remain distinct. Inability to install the newest OS does not automatically mean the phone is unusable, while OS eligibility alone does not guarantee application support, repair-parts availability or continued carrier functionality.
For a used-device decision, combine this lifecycle check with the current repair route and the condition of the actual device, especially when the phone is expected to remain in service for several years.
Official methodology
Keep vendor signals separate
Google Pixel
Keep the Pixel 8-and-later 7-year policy, Pixel 6/7/7a/Fold 5-year policy, and Pixel 5a-and-earlier ended state separate. The clock starts from first US Google Store availability.
Google source →Samsung Galaxy
Use Samsung’s current monthly/quarterly security scope. Absence from the list is not treated as proof of end-of-support; verify the exact Japanese carrier variant.
Samsung source →Combine this with Phase115 before purchase
OS/security support alone does not decide whether an individual used phone is safe to buy. Check ownership lock, network restriction, SIM/eSIM, battery, damage, water exposure and seller warranty separately in Phase115.
