• Trade‑in mode on Android 16+ speeds device assessment by bypassing setup wizard. • A single adb command (tradeinmode getstatus) pulls full device health data instantly. • Secure evaluation requires factory reset, no cellular service, no connectivity, and non‑debuggable build. • The feature supports Android’s device‑longevity and circularity goals, reducing carbon emissions by up to 90%. • Trade‑in mode cuts processing time from minutes to seconds, boosting secondhand market volume. • Developers can integrate the mode via adb for rapid quality checks during device refurbishment.

Article Summaries:

  • **Android 16+ introduces “trade‑in mode,” a new feature that speeds up the assessment of factory‑reset phones and tablets. By bypassing the setup wizard, the mode allows users to retrieve comprehensive device health data-IMEI, serial number, battery cycle count, storage status, and more-via a single ADB command (tradeinmode getstatus). The feature is designed for secure, offline use on factory‑reset devices without cellular service or connected accounts, ensuring only trusted builds are evaluated. Android claims the faster, automated evaluation will streamline the second‑hand market, where used devices emit 80‑90% fewer carbon emissions than new ones, supporting the company’s circularity goals.
