Recommendation: choose models that promise at least 3 major OS upgrades and a minimum of 4 years of security patches; if buying pre-owned, prefer units released within the last 18 months and from manufacturers that publish a clear update schedule and monthly or quarterly patch cadence.
Verify support by checking the manufacturer’s official policy page for the specific model, then open Settings > About phone to read the Security patch level and the platform release number (for example: 13, 14). Cross-reference the model’s launch date with the vendor’s declared upgrade count to calculate the real end-of-life date.
Typical commitments today: Samsung frequently offers 4 major upgrades plus 5 years of security for many flagships and selected mid-range lines; other OEMs such as OnePlus, Xiaomi and Oppo often provide 2–3 major upgrades with 3–4 years of patches. Google’s own handsets vary by generation–always confirm the model page before purchase.
Practical steps: enable automatic patch installation, monitor the security patch level monthly, and set a replacement plan if the vendor’s promise is under three major upgrades (replace within 24–36 months). If official updates stop but longevity is required, consider community builds only after confirming bootloader unlock policy and warranty implications.

If continuous security fixes for at least four years are required, pick a handset with a publicly stated update promise (look for “4 OS releases + 5 years of security patches”) and verify the current security patch date – treat any unit with a patch older than 90 days as insecure for sensitive tasks.
How to verify update eligibility
1) Open Settings → Security → Security patch level to read the patch date; subtract from today to get days since last patch.
2) Find the model name and release year in Settings → About; compare to the manufacturer’s policy page (search “update policy” on the maker’s site) to get the promised count of major OS releases and patch years.
3) If the manufacturer posts a major-release count (e.g., “4 releases”) add that to the launch release number to know the final supported release number for that model.
4) Check community support: LineageOS/GrapheneOS availability and active maintainers often extend life by several years; absence of builds means official updates are the only option.
Actions when the update window ends
Short-term: keep automatic updates for apps on, enable Play Protect, remove banking and password-manager apps from units with outdated patches, use a VPN on public networks, and avoid sideloading unknown APKs.
Medium-term: install an actively maintained aftermarket ROM (LineageOS for broad model support, GrapheneOS for eligible Google models) if security patches are still provided by the ROM community – confirm build dates and signature keys before switching.
Long-term: replace the handset if certified app compatibility or hardware features are required and no official or community updates exist. For purchases, prioritize models released within the last 18 months that include explicit update commitments in writing.

Reference mapping (release → API level, public release year): 14 → 34 (2023); 13 → 33 (2022); 12 → 31 (2021); 11 → 30 (2020); 10 → 29 (2019); 9 (Pie) → 28 (2018). If the handset reports a release older than 11 (API ≤30) or a security patch older than six months, plan for an update path or a handset replacement to maintain app compatibility and security.
